We present results from a survey of all available radiocarbon determinations (the S2AGES database) which show that when calibrated, and compared to the GRIP stratotype of climatic events, the data can be interpreted as five population events in the 15ka prior to the onset of the Holocene. The fine-grained climate record provides an opportunity to study the impact of environmental factors on a human dispersal process that not only shaped subsequent European prehistory, but also the genetic makeup of modern Europeans. The population events have implications for archaeologists and molecular geneticists concerning the timing, direction, speed and scale of processes in Western European demographic history. The results also bear on the role of climatic forcing on the expansion and contraction of human populations and in particular the correlation of ice core and terrestrial records for the onset of warming in the North Atlantic. IZVLEČEK - Kronometrična pozornost se v poznem glacialu zahodne Evrope odmika od datiranja arheoloških kultur k proučevanju ponovne poselitve kontinenta ob koncu zadnje ledene dobe. Predstavljamo rezultate pregleda vseh dosegljivih radiokarbonskih sekvenc (podatkovna baza S2AGES), ki kažejo, da lahko datume, potem ko jih kalibriramo in primerjamo z GRIP stratotipom klimatskih dogodkov, interpretiramo kot zaporedje petih populacijskih dogodkov v času 15ka pred pojavom holocena. Podrobno strukturiran klimatski zapis nam omogoča proučevanje vpliva okoljskih faktorjev na proces človekove razselitve, ki je sooblikoval evropsko prazgodovino in genetski zapis modernih Evropejcev. Populacijski dogodki so pomembni za arheologe in molekularne genetike, ki se ukvarjajo s časovnim usklajevanjem, smerjo, hitrostjo in obsegom procesov v zahodnoevropski demografski zgodovini. Rezultati kažejo na pomen klimatskih pritiskov pri širjenju in krčenju človeških populacij in še posebej na korelacijo med lednimi in kopenskimi zapisi ob začetku segrevanja v severnem Atlantiku. KEY WORDS - Radiocarbon; Calibration; Late Glacial; Settlement patterns; mitochondrial DNA; GRIP; Archaeological Taxonomic Unit Introduction A major population expansion occurred in Western Europe during the Late Glacial (15-11.5ka CAL BP) as the OIS2 ice sheets retreated and unglaciated areas in the north became available for re-settlement. Phylogeographic analysis using molecular evidence assigns 60% of the European mitochondrial DNA lineages (Richards et al. 2000), and an even higher proportion of West European Y-chromosome lineages (Semino et al. 2000), to a population bottleneck prior to an expansion from southwest to northern Europe (Torroni et al. 1998; Torroni et al. 2001; Achilli et al. 2004; Rootsi et al. 2004; Pe- 1 Clive Gamble, William Davies, Paul Pettitt, Lee Hazelwood, Martin Richards reira et al. 2005). A potential signal of the bottleneck has also been detected in patterns of linkage disequilibrium in the autosomes (Reich et al. 2001). Population estimates (Bocquet-Apel and Demars 2000) based on the changing distribution of archaeological sites indicate an increase in the Western European metapopulation, excluding Iberia, from 9000 to 40 000 persons with the corresponding occupied areas augmented from 0.55Mkm2 to 1.12Mkm2. The demic expansion is associated with the Ma-gdalenian, a time-space archaeological taxonomic unit (ATU), which is found in Western Europe from c.22 to 13ka CAL BP and is known for its abundant cave and mobiliary art. However, the temporal sub-divisions of this ATU, based on artefact type fossils and stratigraphic sequences, remain problematic (Laville et al. 1980; Thevenin 1995) such that the timing, direction and pattern of the Late Glacial de-mic expansion are imprecise. Moreover, estimates of the age of the timing of this expansion derived from a molecular clock model for mitochondrial DNA to be c.16ka BP (Torroni et al. 2001) rely upon a number of assumptions and need to be substantiated by independent radiometric means. To address this imprecision, and to examine the correspondence between archaeological and genetic evidence for a population expansion, we present here results from S2AGES, an OIS2 database of radiocarbon determinations from Europe, the Near East and North Africa. The sub-sample described here comprises 2255 determinations from 1200 archaeo- Fig. 1. Late Glacial Western Europe showing sampling regions, the two geographical refugia and probable expansion routes. logical assemblages in Western Europe (Fig. 1) (Pettitt et al. 2003). Figure 2 presents, using CALPAL (Weninger and Joris 2004), the calibrated radiocarbon determinations against the GRIP 818 curve for Iberia, France and North Central Europe. We interpret the changing frequencies of calibrated determinations as a proxy for the timing and direction of demic expansion as well as relative levels of human activity between regions. This method, using dates-as-data, is an established technique to investigate a process such as population dispersal into un-occupied habitats (Holdaway and Porch 1995; Ross 2001). We recognise five major population events for Late Glacial Western Europe (Tab. 1).

Late Glacial population history of Western Europe as reconstructed from archaeological, radiocarbon and genetic evidence. 2 The Late Glacial ancestry of Europeans> Combining genetic and archaeological evidence Population event 1: Refugium, 25ka-19.5ka BP Existing refugium models for Western Europe predict that the lowest metapopulation and the smallest inhabited area co-incided with the last glacial maximum (= LGM 25-21.8ka) (Soffer and Gamble 1990; Strauss 2000a). By contrast, refugium is used here to describe the geographical distribution of population (G refugium), and the contraction, irrespective of geographic extent, of the size of the metapopulation (M refugium) within Western Europe. Iberia, with radiocarbon determinations predominantly from Cantabria and Portugal (Strauss 2000c), was the major G refu-gium into which population contracted throughout the LGM and continued there until GS-2b (Fig. 2). By contrast, human presence was markedly less in France during this long period even though the Southwest, Aquitaine, has often been proposed as a major G refugium (Jochim 1987; Soffer and Gamble 1990; Demars 1996). North Central Europe was never entirely abandoned as shown for example by the site of Wiesbaden-Igstadt dated to GI-2 in the Rhineland (Terberger and Street 2002) but the calibrated curve indicates a low, probably intermittent, human presence in this region. When the M refugium is examined using the S2AGES data, we find it lasted much longer than the LGM, sensu stricto and into GS-2b. Moreover, a radiocarbon database compiled for the Stage 3 project (van Andel et al. 2003) shows very low human presence in North Central Europe for at least the 10ka preceding the LGM in spite of a further six Dansgaard-Oesch-ger oscillations in this time interval (Walker et al. 1999). The Solutrean has been proposed as the ATU of the LGM re- fugium (Strauss 2000b) (Fig. 3). The typological differences between the Solutrean and Badegoulian ATUs are regarded by archaeologists as too great to derive the latter from the former (Djindjian et al. 1999). As recently demonstrated by Terberger and Street (2002) the Badegoulian is most closely related to ATUs in Central and Eastern rather than Western Europe. This suggests the spatially extensive use of the French reindeer steppes by hunting parties with predominantly dispersed settlement patterns and whose population focus lay to the east, rather than the south. The eastern origins of the Badegou- Fig. 2. Overview of Late Glacial radiocarbon dating probabilities for archaeological sites and assemblages, calibrated using CALPAL. The GRIP data form the stratotype for the Late Glacial-Last Termination event based stratigraphy. This recognises, post the Last Glacial maximum (LGM), two warm events (Greenland Interstadials 1 and 2 and two cold events (Greenland stadials 1 and 2). Currently GS-2 is subdivided into three sub-stages and GI-1 into five. In conventional terms GS-1 broadly corresponds to the Younger Dryas, GI-1e to the B0lling and GI-1c-1a to the Aller0d interstadials. Other authors follow GISP2 for the period 25-16ka CAL BP. N = number of calibrated radiocarbon determinations in the frequency curve. 3 Clive Gamble, William Davies, Paul Pettitt, Lee Hazelwood, Martin Richards lian may be reflected in the distribution of mtDNA haplogroups H and pre-V. These are inferred to have an origin around 20-30ka BP either in eastern Europe or the Near East, and to have re-expanded from southwest Europe circa l6ka BP (Richards et al. 2000; Torroni et al. 2001; Pereira et al. 2005). The Y-chromosome cluster R1 shows a similar pattern (Semino et al. 2000; Kivisild et al. 2003). Settlement type in both Cantabria and Southwest France during Population event 1 is dominated by rockshelters as opposed to open sites. Within Population event 1 we include the relatively short lived population expansions from Cantabria (Solutrean) and Central Europe (Badegoulian) into southern France (Fig. 3). We expect that similar demographic pulses were a regular feature of long-term human refugia. Population event 2: Initial demic expansion 19.5ka-I6ka BP The radiocarbon determinations in Figure 4 form the proxy data to infer significant demographic change during GS-2b and the first half of GS-2a. In all areas this is associated with Magdale-nian ATUs (Fig. 4). The change takes the form of an initial step and plateau (Fig. 2) in all regions outside the Cantabrian G refugium before the major rise in the frequency of calibrated determinations during the second half of GS-2a. This occurs during Heinrich Level 1 (17.6-l4.9ka BP) when very low summer sea surface temperatures (SST) have been recorded in core MD95-2040 125km off the Portuguese coast (de Abreu et al. 2003). In both France and Iberia Population event 2 corresponds (Fig. 4), to a pronounced peak in directly dated cave art. The number of sites is small (N = 14) but it is noteworthy that an earlier peak in France corresponds to the Solutrean population expansion we have identified (Fig. 3) and which also corresponds to low summer SST in the Iberian Atlantic during HL2 (24.3-23.1ka BP) (de Abreu et al. 2003). Therefore, cave art may be associated in some regions with small-scale demic diffusion out of the G refugium. This contrasts with earlier interpretations that linked the appearance of cave art to increased population density as people moved into refugia during the LGM and used art as a means to establish territorial rights to key resources such as salmon runs (Jochim 1983). We favour an alternative, first proposed by Housley et. al. (1997), that this small demographic step inferred from the increased number of radiocarbon determinations represents a stage of pioneer settlement in the process of demic expansion as regions Fig. 3. Population events 1 and 2 (LGM to GS-2b) in Iberia and France. Calibrated curves are shown by ATUs. In Iberia the Solutrean is well represented from the LGM through GS-2c. In France the relative presence of the Solutrean, as indicated by the number of radiocarbon determinations, is substantially less suggesting a small demic diffusion north followed by population contraction back to the Cantabrian refugium. The wider context for the development of the Badegoulian (= Early Magdalenian) is therefore the contraction of population back into Iberia after GI-2. 4 The Late Glacial ancestry of Europeans> Combining genetic and archaeological evidence Fig. 4. Population events 3-5 (GS-2b to GS-1) radiocarbon dating probabilities by ATU. Later Magdalenian = ATU1; Epipalaeolithic = ATU2; Mesolithic = ATU3. It is expected that an audit of the dates by precision, accuracy and their archaeological integrity will reduce the outliers in earlier population events (Pettitt et al. 2003). librated determinations in all regions between l6ka and l4.7ka CAL BP. During this 1300 year period the dominant ATU is the Late Magdalenian. Furthermore, the sequence in the radiocarbon curves (Fig. 5) confirm earlier archaeological studies and the interpretation of genetic evidence that within Western Europe demic expansion was from the south to the north and associated with a rapid increase in the metapopulation (Demars 1996; Hous-ley et al. 1997; Bocquet-Apel and Demars 2000; Strauss 2000a). Phase 3.2 of the main demic expansion is represented in two of the three regional radiocarbon curves (Fig. 4) as a plateau that lasts throughout Gl-le (= B0lling interstadial). These 700 years partly coincide with a small plateau in the calibration curve (Weninger and Jöris 2004). This is not considered significant because at this time in southern Iberia the frequency of determinations continues to rise (Fig. 5). beyond the G refugium were explored, assessed and utilised in a more systematic fashion and on a more regular basis. This settlement pattern occurred over much of Western Europe where the main population focus now included southwest France as well as regions in Iberia outside Cantabria/Portugal. Settlement type now comprises both open and naturally sheltered sites. Population event 3: Main demic expansion I6ka-l4ka BP The principal Late Glacial demic expansion occurred in two phases in Western Europe (Fig. 5) over a 2000 year period in GS-2a and GI-1e. In phase 3.1 (Tab. 1) there is a significant increase in the number of ca- Following Housley et al. (1997), we describe the archaeological settlement pattern in Population Event 3 as residential. Large-size, open-air campsites are known (Strauss et al. 1996) from Lake Neuchatel and the Neuwied and Paris basins and these are matched by substantial rock shelter occupations in the Rhine-Danube watershed, the uplands of Southern Germany, Thu-ringia and Belgium. Smaller-scale rock shelter occupations are known from the periphery in the British Isles (Barton 1999) and are comparable in site scale to the pioneer settlement of earlier Population event 2. No doubt small open settlements extended into other northern areas, such as Doggerland (Coles 1998), now inundated by the North Sea. Archaeological evidence suggests two dispersal corridors for Population event 3 to the west and east of the Massif Central (Thévenin 1995). The eastern cor- 5 Clive Gamble, William Davies, Paul Pettitt, Lee Hazelwood, Martin Richards ridor following the Rhone-Saone-Rhine rivers is supported by evidence for the long-distance transfer of raw materials including Mediterranean shells and Baltic amber (Floss 2000) and is studded with residential settlement sites (Street et al. 2001). Population event 4: Population stasis, I4ka-12.9ka BP The interpretation of this population event as stasis rather than contraction illustrates the importance of combining radiocarbon determinations, when used as proxy data for past demography, with archaeological information on settlement patterns. The face-value interpretation from the calibrated curves (Fig. 5) is that after l4ka CAL BP population declined in most regions of Western Europe. However, Figure 6 shows that when the radiocarbon determinations from Northern Europe (Fig.l) are compared for two classes of sites, open and rock shelter/cave, then the reason for the decline in the proxy population curve becomes apparent. Naturally sheltered locations were dominant in both population events 2 and 3. However, this settlement type did not form a significant part of the continuing occupation of the region. On the contrary, open-air campsites continued in importance throughout GI-1 and remained largely unaffected by climate change until the last sub stage Gl-la. We interpret these frequency data as changes in regional settlement patterns, for example from dispersed to nucleated, rather than a decline in the size of the metapopulation. Fig. 5. Population events 3-5 (GS-2b to GS-1) radiocarbon frequencies by region. ATUs represented are Later Magdalenian, Epi-palaeolithic and Mesolithic. As in Figure 4 the dates are unaudited. Population event 5: Population contraction, 12.9ka-11.5 BP The impact of GS-1 (= Younger Dryas) on population size in northern Europe was considerable (Fig. 6) and is confirmed by archaeological surveys (Strauss et al. 1996). However, this northern area was neither abandoned nor used as infrequently as in Population events 1 and 2 (Fig. 2). This suggests a higher metapopulation for Western Europe than the refugium minimum (Bocquet-Apel and Demars 2000) and from this deme came the Holocene/Meso-lithic recovery and population growth. 6 The Late Glacial ancestry of Europeans> Combining genetic and archaeological evidence Comparison with genetic data and the environmental framework Phylogeographic analysis of modern Europeans indicates a major founder effect in the Late Glacial (Richards et al. 2000), with an age estimated from using the mitochondrial DNA molecular clock to circa 16 000 years ago (Torroni et al. 2001; Pereira et al. 2005). The radiocarbon chronology presented here provides the first independent assessment of this estimate with calibrated determinations (Tab. 1, Fig. 2). However, it is not yet possible to be precise about the duration of the constriction itself, except to suggest from the proxy radiocarbon data for regional demography that the neck of the bottle was particularly elongated. Estimates (Bocquet-Apel and Demars 2000) that the metapopulation increased from 9000 to 40 000 in the Late Glacial of Western Europe, excluding Iberia, now have to be considered as demographic growth, independent of in-migra-tion, which occurred in Population event 3.1 over an estimated 1.3ka. The S2AGES proxy data for demic expansion can be considered in the light of two current interpretations of the Greenland ice-core record and its significance for the North Atlantic (Walker et al. 1999; Lowe et al. 2001). At issue is the role of climate forcing in the expansion of human populations. Ameliorating climate at the end of the European ice ages is believed to drive the process of northward expansion of many species from southern refuges (Hewitt 1996; Hewitt 1999; Willis and Whitaker 2000). For this model to stand for human expansion it is necessary to interpret the radiocarbon and GRIP data as time-transgressive. Multi-proxy environmental evidence from terrestrial locations in northern Europe (Walker et al. 2003) suggest this may be the case. These data indicate warming was underway by 15.5ka CAL BP and that a time-trans-gressive interpretation between palaeoclimate archives at different latitudes is appropriate. If correct, the GRIP 818 signal lags behind climatic warming and human, plant and animal migration in the oceanically controlled clima- tes of Western Europe. Using Population event 3.1 as indicative of the effect of this warming on the distribution of human populations we can estimate the lag between climate change in Western Europe and its register in GRIP. Cross correlation Corr (t) of the climate and radiocarbon curves identifies a positive peak only in the Northern Europe and French data. This indicates a significant response in the frequency of radiocarbon determinations some 700 years before climatic warming took place as indicated by GRIP. The width of the peak makes it difficult to ascertain precisely its statistical significance but its simultaneous occurrence in the two regions strongly suggests that it represents the same population event, probably related to biomass changes under climatic amelioration. Furthermore, the Iberian data show a negative correlation with climate change which is consistent with the continued refugium status for this region. However, an alternative model that expansion is not directly linked to ameliorating climate and that the two records are time-locked is supported by marine evidence. High resolution records from an Iberian ocean core (de Abreu et al. 2003) shows in-phase oscillations with GRIP and GISP2 during the last glacial cycle. Significantly Heinrich Level 1 dated 17.6-l4.9ka BP represents the coldest sea surface temperatures off Iberia in the last 70ka and coincides with the major human expansion during population events 2 and 3 (Tab. 1). Therefore, environmen- Fig. 6. Open and sheltered sites from northern France and North Central Europe (regions 6-9, Fig. 1) in population events 3-5. 1051 Clive Gamble, William Davies, Paul Pettitt, Lee Hazelwood, Martin Richards tal forcing on population expansion was linked instead to colder climatic conditions in Western Europe and the earlier Solutrean pulse (Fig. 3) during HL2 confirms this. One solution to the conflicting evidence over the role of climate in human expansion might rest in the model of southern refuges. Climate modelling using sea surface temperatures (van Andel et al. 2003) and evidence from the palaeobotanical (Willis et al. 2000) and faunal (Stewart 2003) archives points to the existence of cryptic refuges during cold phases north of Europe's continental divide. These refuges may have been small in extent and limited in duration but would have acted as an attractor to human populations with an extensive settlement network. By comparison to human expansion, the contraction we document in Population event 5 appears in phase with the GRIP stratotype but is not related to any Heinrich Level. This association supports Foley's (1994) larger analysis of environmental change and evolutionary events among hominins, where the primary influence of climate is on extinction rather than speciation. We conclude that the expansion and contraction of mobile Late Glacial populations in Western Europe may be responding to fine-scale climate change in similar ways and where, at these smaller temporal and spatial scales, population dispersal and decline are analogous to speciation and extinction (Gamble et al. 2004). -ACKNOWLEDGEMENTS- The compilation of S2AGES was supported by a grant from the Leverhulme Trust (F/00180/I).

Even though the distribution and estimated range expansions of major paternal lineages in Southeastern Europe are consistent with the typical European Y chromosome gene pool, the specific role of this region in the process of structuring the European paternal genetic landscape is evident in prehistoric episodes of significant gene flow that diffused from or into the region. IZVLEČEK - Cilj te študije je preučiti obstoječe podatke, ki so osnovani na visoko resolucijskih filoge-netskih študijah variacije kromosoma Y v populacijah jugovzhodne Evrope in v drugih delih Evrazije, z namenom, da ocenimo vlogo regije v procesu prazgodovinske kolonizacije evropskega kontinenta ter pri strukturiranju modernega moškega genskega sklada. Čeprav sta distribucija in predviden obseg širitve glavnih moških dednih linij v jugovzhodni Evropi skladna s tipičnim Evropskim genskim skladom kromosoma Y, se posebna vloga te regije kaže v procesu strukturiranja evropskega moškega dednega genetskega zemljevida, povezanega z dogodki v prazgodovini in genskim pretokom v regijo in iz regije. KEY WORDS - Human Y chromosome; phylogenetic analysis; Southeastern Europe Introduction The human Y chromosome defines male sex through the action of the sex determining region (SRY). It is an atypical segment of the human genome, since it is haploid in most of its length, escapes recombination with the X chromosome, and undergoes uniparental transmission. These properties make the Y chromosome sequence a valuable tool for the purposes of human history reconstruction and studies focused on the dispersal of anatomically modern humans. The non-recombining region of the Y (NRY) is inherited as a single locus that changes exclusively via mutations accumulating over time, thus allowing the preservation of a relatively simple record of genetic history in comparison to nuclear DNA (autosomes). There has been an interest in studying paternal genetic history since the mid-80s (e.g. Casanova et al. 1985; Hammer 1994; Underhill et al. 2000). A constantly growing number of evolutionary informative polymorphisms provide a deeper resolution of human paternal history and evolution. Currently, there are more than 300 known SNPs (single nucleotide polymorphisms) and small indels (YCC 2002; Jobling and Tyler-Smith 2003). In evolutionary genetics terminology, the set of alleles at different biallelic loci along the chromosome is called a haplogroup. Assuming a 1:1 sex ratio, the effective population size of the Y chromosome in a population would be 11 Marijana Pericic, Lovorka Barac Lauc, Irena Martinovic Klaric, Petra Rajic Sikanjic, Branka Janicijevic, Pavao Rudan about one-quarter of that of any autosome. Consequently, a genetic difference depicted by Y chromosomes, in comparison to autosomes, is more susceptible to the effects of random genetic drift that accelerates geographic clustering and differentiation between different (especially small) populations. The general structure of paternal genealogies is compatible and indicative of the common origin of all non-African contemporary populations from a small subset of Africans. Despite disagreement about the time to the most recent common ancestor (TMRCA) of the Y chromosome, its phylogeny roots in Africa around 100 KYA (e.g. Hammer et al. 1998; Underbill et al. 2001; Underbill 2003). The first extensive studies of European Y chromosome dispersal by Semino et al. (2000) and Rosser et al. (2000) showed clinal patterns for the most frequent European haplogroups. Moreover, Semino et al. (2000) grouped more than 95% of European Y chromosomes into 10 phylogenetically distinct haplogroups, of which 70-80% of the Y chromosome gene pool was represented by R1a, R1b, I and N3, and the remaining 20% by J2, E3b, and G. Palaeolithic haplogroups Haplogroup I is the only autochthonous European haplogroup assumed to have arisen in an Epi-Gravet-tian group among the descendants of people who arrived in Europe from the Near East around 25 KYA Fig. 2. R1a frequency distribution in Europe, Northern Africa and Asia Minor (panel a) as well as in Southeastern Europe (panel b). Frequency distributions surfaces are taken from Pericic et al. (2005). R1a frequency data for different Eurasian populations were generated from literature, as listed in Table 1 in Pericic et al. (2005). Fig. 1.11b*frequency distribution in Europe, Northern Africa and Asia Minor (panel a) as well as in Southeastern Europe (panel b). Frequency distributions surfaces are taken from Pericic et al. (2005). I1b* frequency data for different Eurasian populations were generated from literature, as listed in Table 1 in Pericic et al. (2005). (Semino et al. 2000). This haplogroup is almost entirely restricted to the European continent, where it shows frequency peaks in two areas - Scandinavia and Southeastern Europe (Semino et al. 2000). Further phylogenetic subdivision revealed subclades I1a, I1b*, I1b2, and I1c (Rootsi et al. 2004). The geographical distribution of I1a (the highest frequencies in Northern Europe among Norwegians, Swedes and Saami) is considered to be a result of the recoloni-zation of Europe after the LGM from the Francocan-tabrain refugial area (Rootsi et al. 2004). The origin of the less frequent I1c, that covers a wide range of Europe and peaks in northwest coastal Europe, is in concordance with I1a (Rootsi et al. 2004). A completely different distribution pattern is observed in I1b* Y chromosomes, the most frequent haplogroup I clade in Eastern Europe and on the Balkan Peninsula. I1b* reaches maximum frequencies in Southeastern Europe in Bosnia and Herzegovina (Fig. 1). Our results indicate that the homogenous distribution of elevated I1b* frequency among different populations in Southeastern Europe could support the hypothesis of their having a common paternal history shared over a long period of time (Pericic et al. 2005). Rootsi et al. (2004) estimated that I1b* diverged from I* at 10.7+4.8 KYA, possibly in relation to the post Younger Dryas (YD) climate amelioration in Europe, and that I1b* expansion occurred around the early Holocene at 7.6+2.7 KYA. Our coalescent estimate of I1b* (Pe-ricic et al. 2005) is substantially older (11.1+4.8 KYA). This finding suggests that the I1b* lineages might 12 The role of Southeastern Europe in origins and diffusion of major paternal lineages the current level of resolution it is not possible to determine which of three potential episodes of gene flow might have influenced the estimated age in Southeastern Europe: early post-LGM recolonizations from the direction of the Ukrainian refugium, migrations from the northern Pontic steppe in the period between 3000 to 1000 BC, or Slavic migrations between the 5th and 7th centuries AD. Fig. 3. R1b frequency distribution in Europe, Northern Africa and Asia Minor (panel a) as well as in Southeastern Europe (panel b). Frequency distributions surfaces are taken from Pericic et al. (2005). R1b frequency data for different Eurasian populations were generated from literature, as listed in Table 1 in Pericic et al. (2005). have expanded from Southeastern to Central, Eastern and Southern Europe in a period not earlier than the YD to Holocene transition and not later than the early Neolithic (Pericic et al. 2005). Although not yet supported by archaeological evidence, the I1b* spread in Europe suggests that Southeastern Europe could have served as an LGM refugium, as previously suggested by Semino et al. (2000) and Barac et al. (2003). This scenario could be indirectly supported by the recolonization of Northern Europe from the direction of Southeastern Europe by at least two species - the brown bear Ursus arctos (Taberlet and Bouvent 1994) and the European hedgehog Erina-ceus europeus (Hewitt 2000). Another widespread haplogroup in Europe, R1a, is characteristic of Eastern European populations (Fig. 2a). The age of this haplogroup has been approximated to 15 KYA (Semino et al. 2000; Wells et al. 2001). Kivisild et al. (2003) suggested that Southern and Western Asia might be the source of R1 and R1a differentiation. Present R1a distribution in Europe shows an increasing west-east frequency gradient, with the highest frequencies among Finno-Ugric and Slavic speakers (Fig. 2a). R1a frequency shows a decrease in the north-south direction in Southeastern Europe (Fig. 2b), where its age is estimated at 15.8 ± 2.1 KYA (Pericic et al. 2005). This estimate is consistent with the R1a deep Palaeolithic time depth previously suggested by Semino et al. (2000) and Wells et al. (2001). At Its sister clade, haplogroup R1b, was introduced by or arose in an Auri-gnacian group who entered Europe and diffused from east to west about 40 to 35 KYA (Semino et al. 2000). R1b shows a frequency peak in Western Europe and a decrease in Eastern and Southern Europe (Fig. 3a). Even though R1b frequency decline continues from Western to Southeastern and Southern Europe, two intermediate local peaks are evident in Southeastern Europe (Fig. 3b). According to our data, in Southeastern Europe the coalescent estimate of R1b (11.6 ± 1.4 KYA) closely matches the estimate for the I1b* lineages, pointing to the Younger Dryas to Holocene transition as a possible expansion period of these two major Y chromosome lineages (Pericic et al. 2005). Neolithic haplogroups Approximately 20% of European Y chromosomes belong to haplogroups E3b, J2 and G that, due to their decreasing frequency gradients from the Near East to Europe, have been traditionally considered to re- Fig. 4. E3b1 frequency distribution in Europe, Northern Africa and Asia Minor (panel a) as well as in Southeastern Europe (panel b). Frequency distributions surfaces are taken from Pericic et al. (2005). E3b1 frequency data for different Eurasian populations were generated from literature, as listed in Table 1 in Pericic et al. (2005). 13 Marijana Pericic, Lovorka Barac Lauc, Irena Martinovic Klaric, Petra Rajic Sikanjic, Branka Janicijevic, Pavao Rudan present the male contribution of a demic diffusion of farmers (e.g. Semino et al. 2000; Semino et al. 2004; Cruciani et al. 2004). E3b1 shows a frequency peak in Southern and Southeastern Europe (Fig. 4a). In fact, E3b1 shows a rather continuous frequency decline in Southeastern Europe (Fig. 4a). Populations of the Adriatic-Dinaric complex are distinguished from neighboring populations of the Vardar-Morava-Danube river system by a lower frequency of E3b1 (Fig. 4b), possibly due to its different dispersal modes in two proximate geographic regions. Moreover, the Vardar-Morava-Danube river system could have been one of major routes for E3b1 expansion from South and Southeastern to continental Europe, as evidenced in the archeological record (e.g. Tringham 2000). The estimated age of this haplogroup of 7.3 ± 2.8 KYA in Southeastern Europe accords with the time of expansion of the Neolithic in Europe (Cruciani et al. 2004; Semino et al. 2004). Haplogroup J is subdivided into two major clades, J1-M267 and J2-M172 (Cinnioglu et al. 2004). J2-M172 is more frequent in Europe (Semino et al. 2004). In Southeastern Europe the most frequent is haplogroup J2e, which comprises 5% of all chromosomes (Pericic et al. 2005), while haplogroup J2, the main J2 cluster among Greeks and Italians (Di Giacomo et al. 2004), is present at a frequency of less than 1%. The estimated age of the haplogroup J2e in Southeastern Europe (2.8+1.6 KYA), together with its spatial distribution (two frequency peaks positioned in the Balkans and central Italy, Figs. 5a and 5b), may be explained by the maritime spread of J2e lineages from the southern Balkans towards the Apennines later than is traditionally suggested by the demic expansion model (Pericic et al. 2005).

Balkans, with subsequent R1a and I1b* gene flows between Eastern and Southeastern Europe, and the weaker extent of E3b1 dispersal out of Southern and Southeastern Europe towards Eastern Europe than towards Western (especially Mediterranean) Europe. -ACKNOWLEDGEMENTS- This research was supported by the Ministry of Science, Education and Sports of the Republic of Croatia grant for project 0196005 to P.R. Concluding remarks Even though the distribution and estimated range expansions of major paternal lineages in Southeastern Europe are consistent with the typical European Y chromosome gene pool, the specific role of this region in the process of structuring the European paternal genetic landscape is evident in the following prehistoric episodes of significant gene flow: the post-LGM R1a expansion from Eastern to Western Europe, the YD-Holocene I1b* diffusion out of the 14 The role of Southeastern Europe in origins and diffusion of major paternal lineages REFERENCES BARAC L., PERICIC M., MARTINOVIC KLARIC I., ROOTSI S., JANICIJEVIC B., KIVISILD T., PARIK J., RUDAN I., VILLEMS R., RUDAN P. 2003.

The analysis of Hg IY chromosomes revealed several sub-clades with distinct geographic distributions. Sub-clade I1a accounts for most of Hg I in Scandinavia, with a rapidly decreasing frequency towards the East European Plain and the Atlantic fringe; but microsatellite diversity reveals that the Iberian Peninsula/Southern France refugial area could be the source region of the early spread of both I1a and the less common I1c. I1b* extends from the eastern Adriatic to Eastern Europe, and declines noticeably towards the southern Balkans, and abruptly towards North Italy. This cladeprobably diffused after the Last Glacial Maximum from a homeland in the Balkans or Eastern Europe. In contrast, I1b2 most probably arose in southern France/Iberia, underwent a post-glacial expansion, and marked the human colonization of Sardinia about 9000 years ago. IZVLEČEK - Da bi raziskali, kateri aspekti sodobne človeške variacije kromosoma Y v Evropi so značilni za primarno kolonizacijo, pozno glacialno širitev iz refugijev, neolitske širitve in bolj recentne dogodke v genskem zapisu, smo analizirali haploskupine I. Analize kromosoma Yhaploskupine I, so pokazale sub-klade z jasnimi geografskimi porazdelitvami. Sub-klad I1a označuje Hg I v Skandinaviji, s hitrim pojemanjem v smeri proti Vzhodnoevropski ravnici in obrobju Atlantika. Mikrosatelit-ska raznolikost je pokazala, da je bil Iberijski polotok/južna Francija verjetni refugij in izvorno področje, iz katerega sta se razširila oba sub-klada I1a in manj pogosti I1c. I1b* se razteza od vzhodnega Jadrana do vzhodne Evrope in opazno pojema v smeri proti južnemu Balkanu ter strmo upade v smeri proti severni Italiji. Ta klad se je verjetno razširil po zadnjem glacialnem maksimumu iz domovine na Balkanu ali v vzhodni Evropi. I1b2 najverjetneje izhaja iz južne Francije/Iberije in kaže post-glacialno širitev in človekovo kolonizacijo Sardinije pred okoli 9000 leti. KEY WORDS - phylogeny of Y-chromosomal markers; haplogroup I sub-clades; late-glacial expansions; Neolithic dispersals Introduction Although there is sound evidence that the majority of present-day European genes descend from indigenous Palaeolithic ancestors, it is to be expected that the pre-LGM landscape of the spread of genetic variation was profoundly re-shaped during and after the LGM - Late Glacial Maximum (Richards et al. 2000; Semino et al. 2000). The aim of this investigation was to apply the phylogeographic approach to Y-chromosomal haplogroup I, the only known Y-chromoso- mal haplogroup that probably arose in Europe in Palaeolithic times, and which is still common and widespread there, whilst being virtually absent elsewhere. The distribution of haplogroup I was intriguing, with its two high frequency peaks in distant parts of Europe (the Balkan region and Scandinavia); and the further large-scale I haplogroup study by Rootsi et al. (2004) concentrated on achieving a better phylo- 17 Siiri Rootsi genetic and phylogeographic resolution of this hap-logroup, informative for the reconstruction of longdistance gene flows in space and time. Results and Discussion It has been shown earlier that the high frequency of hg I is characteristic of two distant and distinct regions - around the Dinaric Alps (Semino et al. 2000; Barac et al. 2003) and in Nordic populations of Scandinavia (Semino et al. 2000; Passarino et al. 2002; Tambets et al. 2004). In a study by Rootsi et al. (2004), concentrating on haplogroup I phylogeography and phylogeny, more than seven thousand individuals from Europe and the surrounding regions were assessed for the marker M170, which defines hg I. 1104 Y chromosomes from 48 European and 12 populations from surrounding regions which showed the derived M170 C- allele were further genotyped with a set of markers (M253, P37, M26 and M223) that define distinct sub-clades of I, respectively I1a, I1b, I1b2 and I1c. Thanks to the new informative markers used, the improved resolution of phylogeny of hg I enabled to reveal distinct phylogeographical patterns of sub-clades I1a, I1b and I1c, which jointly cover about 95% of hg I individuals. Sub-clade I1a is widely distributed in northern Europe, with its highest frequencies in Scandinavia: in Norwegians, Swedes and Saami, accounting for 88-100% of hg I individuals in these populations and showing rapidly decreasing frequency towards both the East European Plain and the northwestern coastal areas of Europe. Combined analysis of STR diversity and a relative portion of I1a sub-clade among all I lineages suggests that France or possibly more precisely - the Franco-cantabrian refugial area - could have been the source region of the spread of I1a during the post-LGM re-colonization of Europe. The same may apply to the spread of the less common sub-clade I1c. This scenario is also supported by a high positive correlation (0.75) between the geographic distributions of I1a and I1c. I1c covers a wide range in Europe, with the highest frequencies in north-west coastal Europe, and a lower frequency elsewhere (Fig. 1). A totally different distribution pattern can be seen for I1b*, which is the most frequent haplogroup I clade in Eastern Europe and the Balkans. It reaches its highest frequencies in Croatian and Bosnian po- pulations, encompassing almost 80-90% of hg I there. When comparing frequencies in different regions of Croatia (Barac et al. 2003), clear and significant differences between the three southern islands with higher frequency and the mainland and the northerly island of Krk with lower frequency, became apparent. More than half of Croatian hg I sampled individuals - 126 out of 221 (57%) - share an identical STR haplotype, which was named the Dinaric Modal Haplotype. This haplotype was not present in 102 hg 2 chromosomes (according to Job-ling's nomenclature) as reported by Helgason et al. (2000); the most frequent among them was labeled as the Nordic Haplotype (Barac et al. 2003). The phylogenetic network of hg I STR haplotypes points to characteristic haplotype patterns in different sub-clades, which allows us to identify possible founder haplotypes for the different sub-clades, and calculate their possible expansion times according to the method described in Zhivotovsky et al. (2004). The estimates for possible expansion times suggest that the expansion phase of I1a and I1b occurred around the early Holocene and only the less frequent sub-clade I1c shows an earlier age for its STR variation, suggesting that the corresponding mutation arose earlier. High frequency combined with the high diversity of sub-clade I1b in the Croatian population (both mainland and island populations) suggests that during the LGM there might have been a refugium nearby. According to our knowledge, placing of the western Balkans on the list of human refugia during the LGM has not been confirmed so far unambigously by archaeologists. However, the northern part of the Adriatic Sea, including the Dalmatian Islands, was at that time a part of dry land, being covered by water only much later, at the boundary of Holocene (references within Barac et al. 2003). Therefore, one may speculate that the wealth of the traces of human occupancy of the area lies submerged. Nevertheless, it is justified to suggest that the present-day western Adriatic was the reservoir of M170 (I1b) lineages, as well as a starting point for the spread of these lineages during the post-glacial re-colonization of Europe. Meanwhile, the star-like pattern of both, I1a and I1b* STR haplotypes, might be explained by simultaneous re-colonization of Europe from different refugia. I1b* sub-clade dissipates very rapidly west of the Balkans, being virtually absent among Italian, French and Swiss populations, but extending eastwards at i8 Y-chromosome haplogroup I prehistoric gene flow in Europe Fig. 1. A - Median-joining network of combined haplotypes of six STR loci (DYS19, 388, 390,391,392,393) in 25 populations/584 individuals (Norwegians, Estonians, Saami, Swedes, Hungarians, Czechs and Slovaks, Poles, Ukrainians, Croats, Bosnians, Macedonians, Albanians, Greeks, Moldavians, Gagauz, Turks, Italians, Sardinians, French, Dutch, Andalusians, Bearnais, Basques and Swiss). Only haplotypes with frequency >1 were used. Nodes indicate ha-plotypes with sizes proportional to their frequency (smallest node corresponds to 1 individual - only in case of overlap between subclades, otherwise haplotypes with frequency >1 are presented). Haplotypes of different sub-clades are indicated with different patterns. The most frequent haplotype of I1a sub-clade (14-14-23-10-11-13) corresponds to the earlier named Nordic Haplotype and the dominant in I1b* haplotype is the so-called Dinaric Modal Haplotype (16-13-24-1111-13) according to Barac et al. (2003). The possible founder lineage for the third sub-clade, I1c (15-1323-10-12-14), was revealed in Rootsi et al. (2004). B - Median joining network of I1b(xI1b2) and I1b2 lineges based on seven STRs (DYS19, 388, 390, 391, 392,393 and YCAIIa,b). I1b* (YCAIIa,b mostly 21,21 alleles) andI1b2 (YCAIIa,b; 21,10 alleles) lineages are clearly separated from each other by the difference inYCAIIa,b haplotypes. They differ by 10 repeats in YCAIIb allele length that is probably a result of one single mutational event rather than step-by step deletions - in particular because no intermediate repeat variants have been detected. notable frequencies, mostly in the north Balkans and among Slavic-speaking populations, including more eastern Ukrainians. This finding suggests that I1b* may have expanded from a glacial refuge area, which may have been located in the Balkans. As indicated above, there is only limited archaeological evidence for such a refugium in this region at present. Nevertheless, data on the re-occupation of northern Europe from the Balkan region by mammals such as the brown bear Ursus arctos (Taberlet and Bouvet 1994) and European hedgehog Erinaceus europeus (Hewitt 2000), birds such as the European great tit Parus major (Kvist et al. 1999; Kvist 2000) and insects such as the meadow grasshopper Chortippus parallelus (Hewitt 2000), supports its existence indirectly. It seems somewhat less likely though not impossible that I1b* was preserved during the LGM in an area of much better documented Periglacial refugium in the present-day Ukraine. It appears less likely because (a) not only its frequency, but also diversity is higher in the Adriatic region; (b) a branch of I1b* -I1b2-M26 - has a clearly western pattern of distribution, being totally absent in Ukrainians. On the other hand, a clearly visible difference that can be observed in the distribution patterns of I1b* and an outshoot of it - I1b2 - suggests that their separation may have occurred even before the LGM, whereas isolation, genetic drift during the LGM, re-colonization and an unknown number of putative more recent demographic events created the pattern that one observes among extant populations. Meanwhile, the extremely high incidence of I1b2 among Sardinians (about 40%) can be explained by the presence of carriers of I1b2 lineage among the first inhabitants of the island early in Holocene and by the influence of genetic drift thereafter. Certain extent of similarity in distribution patterns of some mtDNA haplogroups, in particular V (Tor-roni et al. 1998; Torroni et al. 2001), with Y-chromosomal hg I sub-branches has been suggested by Rootsi et al. (2004). These findings show that distribution patterns characteristic to Y-chromosomal ha-plogroup I sub-clades are supported by parallel evidence from other genetic markers and probably indicate more general patterns in human past demographic movements. 19 Siiri Rootsi REFERENCES BARAC L., PERICIC M., KLARIC I.

The first stages of these complex investigations were based on observations of numerous phenotype markers. The following phase, which was relatively brief, was dominated by the use of different cytogenetic markers. Finally, at the beginning of this century, the molecular-genetic diversity of the BiH population became the focus of modern research. Autosomal and Y-STR markers, together with mitochondrial haplogroup (Hg) diversity were initially used in the examination of isolated groups, as well as the whole population of modern Bosnia and Herzegovina. The most recent study describes the distribution of Y-chromosome haplogroups in the three main ethnic groups in Bosnia and Herzegovina, and suggests a preliminary hypothesis for the process of peopling this area.

KEY WORDS - molecular markers; Y-chromosome; Last Glacial Maximum; Paleolithic; Neolithic Bosnia and Herzegovina: from the most ancient times to the present Because of its great number of small, more or less isolated, indigenous populations, Bosnia-Herzegovina represents a very interesting area for population-genetic surveys of different levels and approaches. The fascinating diversity of local human populations (obvious even in phenotype characteristics of individu- als), as well as various levels of reproductive isolation can be attributed to the simultaneous and interactive effects of a vast number of factors (geographical, ethnic, religious etc.). Within those areas, each local population exhibits a different degree of openness and isolation and has unique relationships with 21 D. Marjanovic, N. Pojskic, B. Kalamujic, N. Bakal, S. Haveric, A. Haveric, A. Durmic, I. Kovačevic, K. Drobnič, R. Hadžiselimovič, D. Primorac ancestral populations. The results of previous studies show that classic "islands in the land" exist in some regions (Marjanovic et al. 2004). Migration played a very important role in shaping recent conditions, such as, in particular, those relating to the peopling of central Balkan, as well as small regional movements, which were rather frequent because of the geographical position of this area (Malcolm 1994). Archaeological finds indicate that the territory of modern Bosnia-Herzegovina was continuously settled since the Palaeolithic (Imamovic et al. 1998). Stone tools found in north Bosnia date to more than 50 000 years ago (Imamovic et al. 1998). However, the most interesting prehistoric traces of civilization date from the Neolithic. At the beginning of the second millennium BC, the discovery of considerable sources of various kinds of metals attracted new settlers to the Balkan region, including Bosnia-Herzegovina as its central part. In this period the area was inhabited by Illyrian tribes. At the same time, Gals' invasions caused the Illyrians to migrate and settle in the eastern parts of modern Bosnia (Wilkes 1992). By the end of the first century BC, after a hundred-year war, the Romans had defeated all the Illyrian tribes. The Illyrian province was under Roman rule for over 500 years. This was of great importance for this region that, after the construction of military roads and opening of numerous mines (silver, gold, copper, iron etc.), became once again the destination for many adventurers from all parts of the Roman Empire (Klaic 1990). The final division of the Roman Empire made the Balkans an unstable borderland and the crossroads of civilizations, peoples and religions. Two crucial, relatively recent events, along with a number of more minor historic episodes, laid the foundations for the current population structure of region. The first event was the great migration in the sixth and seventh centuries AD that caused the final fall of, first, Western then the Eastern Roman Empire. Documentary evidences suggest that the Goths were the first immigrants to this region (Malcolm 1994); shortly thereafter the Avars and Slavs arrived. In spite of the numerous invaders, there are reasons to believe that the first invasions were blunted by the resistance of well-armed resident Illyrians and the specific landscape, and that the local inhabitants probably completely assimilated most of the first immigrants (Imamovic et al. 1998). According to some authors, this situation persisted for the next couple of decades, when the total 'slavization' of this area began with the arrival of two new Slavic tribes and the foundation of their powerful neighboring countries (Imamovic et al. 1998). The present territory of Bosnia-Herzegovina is located between the areas inhabited by Croats (to the west) and Serbs (to the east). The first document mentioning this region was written by Constantine Porphyrogenitus in 958 (1967). It mentions that Bosnia, being a political and geographical subject, is located in a narrow area along the river. This part of history, in the absence of detailed written documents, is something of a 'twilight zone' for the interpretation of the political situation of that time. Principally, different understandings and presentations of historical facts have been dictated by ideology and politics. However, great mysteries such as the Bosnian heretical church, the term 'Bogomils' (Racki 1931) and the origin of isolated Bosnian populations remain issues for the future. A key fact is that the territory of Bosnia-Herzegovina at that time was the border, or the crossroads of two religious philosophies, Orthodox and Catholic. The second important historical moment for this region was the expansion of the Ottoman Empire in the fifteen century. The conversion to Islam of a large part of the population was a fundamental process in the creation of modern Bosnian history. It was a long-term process, which took 150 years before Muslims were the majority in the former Bosnian sandzak (Malcolm 1994). This process is somewhat controversial, and the only thing that can be refuted with certainty is the hypothesis of forced mass conversion of the indigenous population. Unfortunately, historical dilemmas about some stages of establishing modern Bosnia-Herzegovina society have provided opportunities for various ideological, political, national, even nationalistic manipulations and distortions of the facts. Modern Bosnia-Herzegovina is a multi-ethnic and multi-religious country, with a very stormy recent history. In various public and scientific media, many recent conflicts were sought through different interpretations of some parts of its history. Therefore, every population-genetic study based on the analysis of molecular markers suitable for detecting migration and micro-evolutionary phenomena, with 22 Most recent investigation of peopling of Bosnia and Herzegovina: DNA approach utterly reliable and exclusively scientific result presentation, can create new perspectives, but also raise questions about the structuring demographic characteristics of this area. The development of population genetic studies Fundamental genetic studies of different human, animal or plant populations are based on a preliminary understanding of the nature of molecular marker variations in observed populations. This universal rule, applicable to a wide range of organisms as potential research subjects, is especially important when Homo sapiens is the focus of study. Modern population-genetic studies have changed significantly, especially in the last two decades. Previous studies were based on the observation of classical phenotypic markers. Population-genetic studies that simultaneously analyze the diversity of numerous, carefully selected, phenotypic characteristics can result in interesting information about micro-changes in the genetic structure of observed populations over a certain period. However, many of the informative phenotypic markers are limited by a lack of clarity in defining the heritable and non-heritable components that form most of the phenotypic attributes of an organism, especially those which are easiest to detect. Human population genetics often uses intra- and inter-population distributions of genetic molecular markers in and between analyzed parts of population in order to elucidate their demographic and migration history (Wells et al. 2001). The development of new molecular-biological techniques has improved the molecular markers system. Among these markers, of primary importance are the STR (short tandem repeats) sequences, located on autosomal chromosomes (Bowcock et al. 1994), and SNP (single nucleotide polymorphisms) haplotypes (Jin et al. 1999). Even nowadays, these two kinds of markers can significantly contribute to a better understanding of the demographic and migration processes that affected the gene pool of now living populations. Polymorphic markers, such as biallelic and STR, located in the non-recombining part of Y-chromosomes (NRY), are also known as holiandric markers, because of their transmission from father to son. The absence of recombination, as well as patrilocal marriage in approximately 70% of modern societies, makes this unique item of human chromosomal sets exceedingly useful in the study of large-scale evo- lutionary events in human history and population genetics phenomena in large and small, relatively isolated communities. In the past few years a substantial amount of population data regarding the non-recombining part of Y-chromosomes has appeared (YCC 2002 and references therein). The spate of surveys in this field began with papers in the mid-1980's (Casanova et al. 1985) Markers located in this part of the human genome have an important role in evolutionary studies (Hammer et al. 1996; Poloni et al. 1997; Rosser et al. 2000), as well as in forensic (Jobling et al. 1997) and medical genetics (Jobling and Tyler-Smith 2000). The most frequently used markers at that time were RFLP (restriction fragment length polymorphism) or STR loci (YCC 2002). A historic breakthrough was made by the utilization of the DHPLC (denaturing high-performance liquid chromatogra-phy) method in the investigation of binary markers from the non-recombining portion of Y-chromosomes (NRY) (Underhill et al. 1997). As reported in some papers (Underhill et al. 2000; Shen et al. 2000; Hammer et al. 2001), over a short period of time, this method allowed the identification of over 200 SNPs and short insertion/deletion (indel) positions (YCC 2002). A very low mutation rate characterizes these polymorphisms' (named for this reason Unique Event Polymorphisms - UEP), making them suitable for the identification and detection of parental lineages stretching back thousands of years (YCC 2002). In order to set up a more flexible nomenclature system and to provide a complex NRY binary haplo-group tree, Y Chromosome Consortium (YCC), established by leading experts in Y-chromosome analysis, suggested a universal system in 2002 that is widely accepted today (YCC 2002). According to this system, Y-specific binary haplogroups (often denoted simply as haplogroups) refer to chromosome clusters characterized by the deepest UEPs. These clusters are more stable, but at the micro-evolutionary level, less informative than haplotypes defined by the more variable STR markers (Jobling and Tyler-Smith 2003). On the whole, a total of 16 major haplogroups (denoted by letters: A-R) were identified and the study of their distribution (phylogeography) provided important information about the peopling of different geographical areas, post-glacial and Neolithic expansions (Underhill et al. 2001). As to Europe, more than 90% of the Y-chromosomes belong to a few (E-SRY4064, I-M170, G-M201, J-12f2, R-M17and R-269) principal haplogroups (Semino et al. 2000; 2004; Cruciani et al. 2004; Rootsi et al. 2004). 23 D. Marjanovic, N. Pojskic, B. Kalamujic, N. Bakal, S. Haveric, A. Haveric, A. Durmic, I. Kovacevic, K. Drobnic, R. Hadziselimovic, D. Primorac Overview of population-genetic studies in Bosnia and Herzegovina during the last three centuries Anthropo-genetic studies in Bosnia-Herzegovina were begun by the Austro-Hungarian government (Hadziselimovic 1984). The first known bio-anthropological analyses of the population conducted by Austro-Hun-garian army doctors can be considered an initial phase in determining its genetic structure (Himmel 1887). It is important to stress that all of the studies were based primarily on the observation of phenotypic traits such as blood groups (Kalic, Kostic 1934; Berberovic et al. 1973), color blindness (Berberovic 1969), the shape of lobules (Hadziselimovic 1970), PTC sensibility (Berberovic et al. 1973), thumb flexibility (Hadziselimovic & Brdar 1979), or analysis of the effect of some factors that disturb genetic equilibrium (Hadziselimovic 1983). The first steps were taken in investigating the variety of the fundamental, molecular-nuclear and mitochon-drial DNA markers for diversity analyses of isolated Bosnia-Herzegovina populations at the beginning of this century (Marjanovic et al. 2004; Kapur et al. 2004; Marjanovic et al. 2005). Following analysis of STR marker variation, autosomal (Marjanovic et al. 2006), and Y-chromosome markers (Marjanovic et al. 2005a) were studied in order to establish a reference sample and to incorporate data about the molecular biodiversity found in BiH in a regional database (REBID-a). Finally, the most interesting and controversial results were obtained trough the observation of 28 Y-chromosome biallelic markers within 256 males (90 Croats, 81 Serbs and 85 Bosniacs) from Bosnia-Herzegovina (Marjanovic et al. 2005b; 2005c). The Y-chromosome approach (summary of published articles) The people of Bosnia-Herzegovina display European specific haplogroups that probably appeared in different glacial refuge areas of Europe (I-M170, R-M17 and RM269 from Balkan, Ukrainian and Fran-co-Cantabrian refuges, respectively), and haplogroups considered to have originated in Africa (E-SRY4064) and the Middle East (J-12f2) and to have arrived in Europe through a prolonged gene flow. However, the presence of the HgI sub-haplogroup I-P37 in more than 50% of the examined Y chromo- somes sets the population of Bosnia-Herzegovina apart from the majority of other European regions. Taking into account that a Palaeolithic origin for the P37 mutation in this Balkan district has been suggested (Rootsi et al. 2004), it is possible that the postglacial expansion of a population with a high frequency of I-P37 from one of the refuges in the Balkans played a major role in the creation of the gene pool of modern Bosnia-Herzegovina. HgE is the second most frequent haplogroup in Bosnia-Herzegovina; its presence in Europe has been attributed to multiple migrations from the Middle East and North Africa during and after the Neolithic (Cruciani et al. 2004; Semino et al. 2004). HgE is almost exclusively represented by the sub-clade E-M78. It is worth mentioning that the clinal distribution in Europe of E-M78 and its internal micro-satellite variance have been attributed to dispersals in Neolithic and post-Neolithic times from the Balkans to all directions, as far as Iberia to the west and, probably also to Turkey in the southeast (Cinnioglu et al. 2004; Cruciani et al. 2004; Semino et al. 2004). In this framework, our data suggest that this expansion would have significantly affected the gene pool of Bosnia-Herzegovina. Haplogroup J is another haplogroup that arrived in Europe from the Middle East, and its sub-clades probably marked complex migration processes during and after the Neolithic period (Cinnioglu et al. 2004; Di Giacomo et al. 2004; Semino et al. 2004). In the Bosnia-Herzegovina population this haplogroup, with almost all of its known sub-clades, is found mainly in the Bosniacs. The detected J sub-clades are J-M267, which has been associated with Arab expansion; J-M92, which suggests genetic links between Anatolia and southern Italy; J-M67, which is frequent in the Caucasus; and finally J-M102, which shows frequency peaks in the southern Balkans and central-southern Italy. R-M17 is the prevalent sub-haplogroup of Hg R, as previously observed in other eastern European populations (Semino et al. 2000; Passarino et al. 2001; Wells et al. 2001). Its frequency perfectly fits the expected distribution of R-M17, which is found almost exclusively in Eastern Europe, with a decreasing gradient from northeast to south-west. This gradient, initially attributed to expansion(s) from a Ukrainian glacial refuge (Semino et al. 2000), could also be due to infiltrations of Indo-European speaking peoples from southern Russia about 2000 years ago (Jovanovic 1979; Barac et al. 2003), as well 24 Most recent investigation of peopling of Bosnia and Herzegovina: DNA approach as to the arrival of Slav clans during the 6th and 7th centuries. However, to evaluate this latter hypothesis, detailed analyses of R-M17 and internal STR diversity in the Bosnia-Herzegovina population are required. The presence of the R-M269 sub-haplogroup in the sample is of interest. Despite the relatively low frequency of this marker, it indicates that the gene pool of the ancestral population(s) of the Franco-Canta-brian refuge area also contributed to some extent to this region of the Balkans, as additionally attested by analyses of the mtDNA (Achilli et al. 2004). The first PC analysis (Marjanovic et al. 2005c) suggests that the three ethnic groups are genetically extremely close to each other, and closely related to other populations of the Balkans. However, the second PC tends to separate the Croat group from other populations, probably as a result of the aforementioned effects of genetic drift and founding events on this ethnic group. On the whole, our data suggest three main factors in the gene pool foundation of modern Bosnia-Herzegovina: (a) post-LGM expansion - possibly from a LGM refuge area in the Balkans, (b) complex migratory processes from Central Asia and Eastern Europe and (c) the numerous Neolithic and Post-Neolithic migration events that contributed haplogroups considered to be of African and Middle Eastern origin. The main objectives of possible future studies of the peopling of Bosnia and Herzegovina The outcome of this study is a possible account of the pattern of settlement in the area of modern Bosnia-Herzegovina. For the purpose of further elaboration it is necessary to insist on more of the basic parameters in future studies. A multi-disciplinary approach is required in order to investigate fully all the pre-historic and historical events relative to the peopling of Bosnia-Herzegovina and the Balkans. All historical, archaeological and other findings relevant to determining migratory factors and modern micro-migratory processes should be analyzed. The results of this study should be compared to those of previous population-genetic studies based on observations of a wide range of both classic and molecular markers. Presented scenario, based on the results of holandric marker variation analysis, could benefit from such an approach. The second parameter, which points to the dating of primary mutations in samples of the Bosnia-Herzegovina population, is highly notable. With the intention of estimating the possible time of mutation occurrence, analyses of Y-chromosome STR markers, and their frequencies and correlations within the detected haplogroups can be of great value. The results of these analyses would facilitate the precise reconstruction of regional migration patterns. Preliminary results based on the observation of 100 males from Bosnia and Herzegovina, have already yielded interesting results (Marjanovic et al. 2006). Eighty-one different Y-STR haplotypes (from a total number of 100 samples obtained) were detected: 69 of them were unique, 7 appeared twice, 4 appeared three times, and 1 five times. Six of twelve not singleton haplotypes were shared by different population groups: two of them by Croats and Bosniacs, two by Bosniacs and Serbs, and the last two by Serbs and Croats, thus testifying almost certainly to recent gene flows between groups. Most importantly, the results must be evaluated with an expanded sample. The sample of 256 individuals is larger (in European proportions and for such a relatively small population as Bosnia-Herzegovina) than many other samples investigated so far. Also, sample size for each of the three major ethnic groups completely meets the standards for this type of investigation, and is larger than those used in previous European studies of much larger populations than this one. The fact that the subjects are from more than 50 different locations in Bosnia-Herzegovina speaks in favor of a representative sample. However, regarding the high specificity and close relations of the ethnic groups, their common historical development, specific micro-migrational paths and the specific historical circumstances under which these groups developed, it is important to examine the intra-population diversity of regional subpopulations. For instance, the Croat population could be analyzed including sub-samples from Herzegovina, Middle Bosnia and Posavina; the Serbs through Herzegovina, Eastern Bosnia and Krajina groups; while the Bosniacs could be typed by comparing Herzegovina, East-Middle Bosnia and Western Bosnia groups. However, all the other demographic-genetic characteristics of the local groups of these populations can be taken into consideration. This approach can resolve the question of whether differences observed through this study are due to inter-populational (ethnical) or, more probably, intra-populational (regional) characteristics. 25 D.

Primorac Until these complex studies are conducted, it is important to state that all findings, implications, hypotheses, reconstructions and models of this study are based on the results of the analyses of a screening-sample of the Bosnia-Herzegovina population and its relation to previously studied Eurasian populations. Recent scientific studies from this field (Semino et al. 2000; Barac et al. 2003, and others) offer one truly interesting and completely new scenario. However, extreme caution is required in presenting these scientific results in the public media in order to avoid misinterpretation of the facts and unscientific speculation that could have unforeseeable consequences. -ACKNOWLEDGEMENTS- All Y-chromosome SNP analyses and results were obtained at the Dipartimento di Genetica e Microbiologia 'A.

Dating the CCR5-A32 bp deletion to the Mesolithic in Sweden and its implications for the Meso/Neo transition Kerstin Liden1, Anna Linderholm1, Anders Götherström2 1 Archaeological Research laboratory, Stockholm University, 106 91 Stockholm, Sweden kerstin.liden@arklab.su.se, anna.linderholm@arklab.su.se 2 Department of Evolutionary Biology, Norbyvägen 18D, 751 05 Uppsala, Sweden Anders.Gotherstrom@ebc.uu.se ABSTRACT - Genetic variation in the chemokine receptor gene CCR5 has received considerable scientific interest during the last few years. Protection against HIV-infection and AIDS, together with specific geographic distribution are the major reasons for the great interest in CCR5 32bp deletion. The event for the occurrence of this mutation has been postulated by coalescence dating to the 14th century, or 5000 BP. In our prehistoric Swedish samples we show that the frequency of 32pb deletion in CCR5 in the Neolithic population does not deviate from the frequency in a modern Swedish population, and that the deletion existed in Sweden already during the Mesolithic period. IZVLEČEK - Med znanstveniki je bilo v zadnjih nekaj letih precej zanimanja za genetsko variacijo na kemokinskem receptornem genu CCR5. Glavna razloga velikega zanimanja za zdrs 32bp na CCR5 sta zaščita proti okužbi z virusoma HIV in AIDS ter specifična geografska porazdelitev. S pomočjo 'datiranja zlitja'je bilo predpostavljeno, da se je ta mutacija pojavila v 14. stoletju AD ali pa 5000 BP. Na švedskih prazgodovinskih vzorcih pokažemo, da ni bistvenega odklona v frekvenci zdrsa 32pb na CCR5 med neolitsko in moderno švedsko populacijo in da je mutacija na Švedskem obstajala že v mezolitiku. KEY WORDS - CCR5-A32; Bubonic plague; Smallpox; Mesolithic; Neolithic Introduction The product of the CCR5 gene is a member of a se-ven-transmembrane G-protein-coupled receptor family, and is important for the cell entry of the human immunodeficiency virus HIV-1 (Alkhatib et al. 1996; Choe et al. 1996; Deng et al. 1996; Doranz et al. 1996; Trkola et al. 1996). In 1996 a 32bp deletion in the CCR5 gene was reported which truncates the protein and appears to provide almost complete protection against infection by HIV-1 (Liu et al. 1996; Samson et al. 1996; Dean et al. 1996; Omet-to et al. 1999). In homozygotes for 32bp deletion the protection is well documented, but there are different opinions about the protective effect of heterozygosity against HIV-1, although it seems to delay the outbreak of AIDS (Samson et al. 1996; Dean et al. 1996; Huang et al. 1996; Michael et al. 1997). The CCR5 32bp deletion seems to be restricted to Caucasian populations. However, the frequency of the mutation varies widely among European populations. Whereas the frequency is quite high in St. Petersburg, Russia (0.166), and in Sweden (0.143), it is considerably lower in the southern parts of Europe, e.g., in Spain (0.050) and Greece (0.041) (Lucotte 2001). However heterozygosity for the deletion was found at a frequency of 0.23 in a Swedish HIV positive group (Bratt et al. 1998). Since that study was cross- 29 Kerstin Liden, Anna Linderholm, Anders Götherström sectional and not prospective, this frequency may represent a population subjected to a different selection pressure than an ordinary Scandinavian population. In cases where the deletion has been found in non-Caucasian populations, there has usually been continuous contact and a likely admixture with Caucasians (Liu et al. 1996; Samson et al. 1996; Dean et al. 1996). The geographic distribution of 32bp deletion in Europe has been explained in several ways, as e.g., genetic drift (Martinson et al. 1997) or positive selection due to resistance to a major disease (Dean et al. 1996). Based on coalescence, 32bp deletion has been estimated to have appeared approximately 700 years ago (Stephens et al. 1998). Consequently, it has been speculated that the Black Death (Yersinia pestis) caused a positive selection (Stephens et al. 1998; O'Brien 1998). The basis for this hypothesis is that CCR5 may be involved in the mechanism of Yersinia-induced macrophage apoptosis (Stephens et al. 1998). If the Black Death, believed to be caused by Yersenina pestis, resulted in a positive selection, this has to be a fairly recent process, since the outbreak of this disease was in the mid 14th century. However, according to Galvani and Slatkin (2003), the bubonic plague, although severe, could never have driven the frequencies to over 10% in the short time span of 700 years. In another study, it was postulated that the mutation originated about 2000 years ago, somewhere in north-eastern Europe (Libert et al. 1998). In later publications, smallpox is thought to be a more likely candidate, where the selective pressure from this virus would have pushed the frequency of 32bp deletion across Europe into today's figures (Klitz et al. 2001; Galvani and Slat-kin 2003). In a recent publication Sabeti et al. (2005), has pushed back the estimate of the occurrence of the CCR5-A32 allele to over 5000 years ago. There are also several articles suggesting that the deletion was dispersed by the Vikings along its present gradient across Europe (Lucotte 2001 and Lucotte and Die-terlen 2003). In 2005 the CCR5-A32 was detected in human Bronze Age skeletons from Germany by Hummel et al., and this is the first evidence that the mutation existed before thel4th century plague outburst. Although there are disagreements about the time for the first occurrence of 32bp deletion, the cause of the event, and the distribution of the deletion all seem to agree on the fact that the deletion originated from a single historical mutation event. Here we want to address the question regarding the deletion's first occurrence and distribution by extracting DNA from well-known and well-dated prehi- storic human and animal bones and teeth. Of specific interest is a date for the occurrence of the deletion that precedes 5000 BP, i.e. approximately the Mesolithic-Neolithic transition in Scandinavia. In Scandinavia the Mesolithic stretches from around 8300 to 4000 BC. It is a period connected to the end of the last glaciation, and marks a shift in climate towards a warmer period. During this period people began to colonise southern Sweden, both along the coasts and inland. In this study we have included samples dating to the Mesolithic from Skateholm in the south, and Huseby Klev from the west coast. The Neolithic period began in Sweden with the introduction of farming around 4000 BC, and it ended around 1800 BC with the introduction of the Bronze Age. During the middle Neolithic in Sweden, there were three main cultures: the Funnel Beaker (TRB), the Pitted Ware (GRK) and the Battle Axe (STY) cultures. We have analysed human and animal bones and teeth from two of these cultures, the Funnel Beaker culture complex that is believed to be connected with the introduction of farming and cereal cultivation, and the GRK-complex that consists mainly of a set of hunter/gatherer dwelling sites and cemeteries along the Scandinavian Baltic coast and the major Baltic Islands. The GRK are represented by samples from the islands of Gotland and Aland, and the TRB samples are represented by two passage graves in central Sweden (Fig. 1). The individuals from Dragby represent the last phase of the Neolithic in Sweden, thus this case study encompasses more than 5000 years. Materials and methods Bones and teeth from two Mesolithic and six Neolithic sites were chosen for this study. The two Mesolithic sites used in this study are Hu-seby Klev, radiocarbon dated to 7000-6500 BC, and Skateholm, radiocarbon dated to 5250-4900 BC (Fig. 1). Four individuals were analysed from Huseby Klev (Hkl, Hk2, Hk3 and Hk4), a Preboreal/Boreal site that was subjected to a rescue excavation in 199394 by Bengt Nordqvist (Nordqvist 2000). Next we analysed six individuals from the Skateholm site (burials 4, 5, 7, 12, 63a and 63b) that was excavated in the early 1980s by Lars Larsson (Larsson 1988). The first Neolithic site, Ire on the island of Gotland (Fig. 1), is a cemetery belonging to the Pitted Ware culture complex (GRK) which was excavated in diffe- 3° Pushing it back.

The A32 mutation of CCR5 was found in human material from Skateholm, Rossberga, Visby, Ire, and Dragby, indicating that the mutation is at least as old as these sites. We added a bone from a cow deposited in this passage grave, for the same reason as stated above. The last samples are from Dragby, a passage grave excavated by Marten Stenberger in 1958/59 (Gejvall 1963). The dating of this tomb is complicated, since it was superimposed by a Bronze Age mound. However, the 14C dates, 2290-1690 cal BC (Roumelis 2002), imply that this site was in use during the late Neolithic. Four individuals were analysed (H4/A, F15/44, F8/44 and F2f2/45). rent periods after its discovery in 1914 (Janzon 1974). Five individuals (burials 6b, 6c, 7a, 7b and 7c) were analysed from this site, which has been 14C dated to 3000-2100 cal BC (Janzon 1974). We also extracted DNA from a horse deposited in the settlement layers connected to the burials, in order to control for contamination and bone preservation. The other GRK site on Gotland, Visby (Fig 1.), is a cemetery that was last excavated in 1960-62 by Erik Nylen (Janzon 1974). Here 12 individuals were selected for analysis (burials 2/09, 2/24, 2/39, 3b, 13, 19, 19/37, 23, 27, 30b, 31 and 33). They have been 14C dated to 3000-2500 cal BC (Janzon 1974). The next site to be analysed is Jettböle (Fig 1.), also a GRK settlement on an island in the archipelago of Aland, excavated by Björn Cederhvarf from 1905 until 1911 (Cederhvarf 1912). From this site, 3 individuals were analysed (J1, J2 and J3). They have been radiocarbon dated to 3370-2910 cal BC (Liden et al. 1995). The other samples are from two passage graves, Rös-sberga and Hjelmars Rör (Fig. 1), both from Väster-götland in central Sweden and belonging to the Funnel Beaker culture complex (TRB). Five different individuals from each passage grave were analysed. Fourteen out of sixteen 14C samples date Rössberga to 3506-2143 BC; the other two samples date Rössberga to the late Bronze Age (Persson & Sjögren 1995). Rössberga, which was excavated in 1962 by Carl Cullberg, will be treated here as a middle Neolithic passage grave (Cullberg 1963). Eight 14C samples date Hjelmars Rör to 3350-2700 BC. The passage grave was first excavated in 1868 by Bror Emil Hildebrand, but was revisited in the 1990s by Tony Axelsson and Per Persson (Persson & Sjögren 1995). Most publications on DNA from prehistoric material concern mitochondrial DNA (e.g. Hagelberg & Clegg 1991; Krings et al. 1997; Krings et al. 1999; Handt et al. 1994, Torroni et al. 2000, Hofreiter et al. 2002, Forster 2004, Starikovskaya et al. 2005). However, a number of studies have also been performed on nuclear, single copy markers from ancient tissue (e.g. Beraud-Colomb et al. 1995; Zierdt et al. 1996; Ovchinnikov et al. 1998; Göther-ström et al. 1997; Greenwood et al. 1999; Noonan et al. 2005; Poinar et al. 2005). We designed a suitable (<150bp) primer system for the part of CCR5 that carries the 32 bp deletion, i.e. in this study we use a single copy nuclear marker applied to ancient DNA. In all cases, except for the cow, teeth were used as the source material for DNA extraction. Samples were extracted and prepared for PCR according to Liden et al. (1997) and Anderung et al. (2005). This study was conducted in two stages, and because of this the DNA extraction methods varied. Part one was done using a guanidium thiocyanate and silica extraction (Liden et al. 1997), and the second part was done using an extraction method called fishing (Anderung et al. 2005). A set of three primers was designed to give an easily detectable indication of the presence or absence of the 32bp deletion (Tab. 1), i.e., a system that amplifies fragments of different length depending on whether the 32bp deletion is present or not, and to amplify highly degraded DNA. This primer system was used in both set-ups. DNA was amplified with Amplitaq gold™ (Perkin El-mer)/HotStarTaq (Qiagen) to receive the hot start 31 Kerstin Liden, Anna Linderholm, Anders Götherström and time-release effect (Gotherstrom et al. 1997). The 25 |l reactions contained 50 mM KCl, 10 mM Tri-HCl pH 8.3, 2.25 mM MgCl2, 0.2 mM of each dNTP, 0.5 |M of each primer, 1 U Taq-polymerase (Amplitaq gold™, Perkin Elmer, HotStarTaq, Qiagen), 10/9 |l template DNA and 2% glycerol/none. Hot start was performed automatically, due to the enzyme used. The amplification cycles were initiated by a 45 sec/5 min. denaturation step at 95° C to activate part of the enzyme and save the rest for later cycles; this was then followed by 45/30 sec. at 94° C, 1i/2/1min. at 50° C and 1 min/30 sec. at 72° C. This cycle was repeated 55/45 times. Finally, an extension step at 72° C for 7/5 min. followed. The result was detected on a 3%/1.5% ethidium bromide stained agarose gel exposed to 40 V for 1h. One primer (CCR5:1) anneals upstream the sequence, one (CCR5:2) anneals downstream on the other side of the 32bp deletion, and the third primer (CCR5:3) anneals within the 32bp deletion. Thus, an individual homozygous for the deletion will have one fragment (91bp) amplified, an individual homozy-gous for the wild type will have two fragments (105bp and 123bp) amplified, and a heterozygous will have three fragments (91bp, 105bp and 123bp) amplified. The result was confirmed by sequencing on a Pharmacia ALF express™ with an Amersham Pharmacia Biotech Cycle Sequencing kit. A short mtDNA fragment, 16131-16303, according to the reference sequence from Anderson et al. (1981), was amplified and sequenced from a part of the material to confirm that the DNA was from Primer name Primer sequence CCR5:I 5'TCCTTAGTAGAAATGGTCTAG3' CCR5:2 5'GTCGGGGTTCTACTGATAG3' CCR5>3 5'GAAATTACAGACCTTTAAGAAG3' L16131 5'CACCATGAATATTGTACGGT3' H16303 5'TGGCTTTATGTACTATGTAC3' HBB:i 5'GATATAAAAAAGAAGACCCAGTAG3' HBB:2 5'TACCTGAGTCATATGTAATATTCC3' HTGIO:I 5'GAATTCCCGCCCCACCCCCGGCA3' HTGIO:2 5'TTTTTATTCTGATCTGTCACATTT3' Tab. 1. Primer name and primer sequences used in the study. The system used to detect presence of the 32bp deletion of the CCR5 gene is based on three primers CCR5:1, CCR5:2, CCR5:3. The D-loop system is a simple two-primer system L16131 & H16303 (Anderson et al. 1981). The primers used for the horse were HTG10:1 and HTG10:2 (Mark-lund et al. 1994) and for the cow HBB:1 and HBB:2 (Steffen et al. 1993). different individuals in the first set-up. If authentic DNA was extracted, there should among all samples be several haplotypes present based on this short HVR1 sequence, but only one haplotype in each sample. The same protocols, with minor changes, used for CCR5 amplification and sequencing were used for the amplification and sequencing of the mtDNA fragment. However, only 45 cycles were used, and L16131 and H16303 (Tab. 1) replaced CCR5:1, CCR5:2 and CCR5:3. The primers used for the horse and cow were HBB:1 and HBB:2 (Marklund et al. 1994) and HTG10:1 and HTG10:2 {Steffen et al. 1993) respectively. In the second part of the study, all replications were performed in an independent laboratory, Centro Mixto UCM-ISCIII de Evoulcion y Comportamiento Humanos (Madrid) in order to detect contaminations and prove the authenticity of the ancient DNA (Hofreiter et al. 2001). One tooth permits one extraction, which gave enough material for ten PCRs. Whenever possible, at least two samples were taken from each individual, but only one extraction could be carried out on each individual from the passage graves due to the problem of separating individuals in a passage grave. However, thanks to high reproducibility within the extraction, we could trust the results from the ten individuals from the passage graves. Moreover, a robust protocol including extraction blanks, carrier effect blanks, PCR blanks, UV irradiation of reagents, fragment size control etc was applied (Gotherstrom & Liden 1998). To further test the state of preservation, we extracted another large bone protein, collagen, according to Brown et al. (1988) on both human and animal samples. Here the extracted amount of collagen, the absolute amounts of carbon and nitrogen, as well as their ratio provide information on the state of preservation (DeNiro 1985). We also tried to amplify DNA extracted from the horse and the cow with the primers used for the humans, to test for contamination. Results and discussion The collagen data were all in accordance with bones that are well preserved. In bones positive for DNA, no samples contained less than 0.66% of collagen, calculated on total bone, and the C/N ratios were all within the accepted limit of 2.9 - 3.4 (except for 3 samples), as well as the absolute values of carbon and nitrogen (Tab. 2) (De Niro 1985). It is therefore reasonable to believe that DNA was also well pre- 32 Pushing it back. Dating the CCR5-A32 bp deletion to the Mesolithic in Sweden and its implications for the Meso/Neo transition served in the samples (Gotherstrom et al. 2002). There is also a correlation with previously published quantitative data (Malmstrom et al. 2005), where good preservation has been indicated on the Baltic island of Gotland. That the extracted DNA is authentic was further proved by the result of the mtDNA, where we have four different haplotypes distributed over two cemeteries, and that no products were obtained from the extracted animal DNA amplified with the human primers (Tab 2.). We were able to extract DNA from 19 out of 50 samples, representing in total 46 individuals, i.e. a 38% success rate (Tab. 2). We were also able to extract and sequence DNA from two different teeth from the same individual in two of the burials from Ire. Of the 19 samples, now representing 17 individuals, one individual was dated to the Mesolithic and came from Skateholm, and 16 individuals were dated to the Neolithic. Of the Neolithic samples, six individuals can be attributed to the pitted ware culture, nine to the funnel beaker culture, and one to the late Neolithic. The complete sample is in Hardy-Weinberg equilibrium (p = 0.661), and does not differ in frequencies (17.1%) of the CCR-A32 mutation from a modern Swedish population (14.3%). It could be argued that the small sample size, 17 individuals or 34 alleles, is not statistically significant. A further argument could be that the five individuals from one megalith tomb could be related i.e., providing a smaller number of alleles than we calculate. This is also obvious in the case of Ire, where the individuals were sampled from one burial, and one individual proved to be a heterozygous, while the others proved to be ho-mozygous for the mutant allele. Two alternative explanations for the specific distribution of the CCR5 32bp allele have been suggested, where one is a selection process related to a specific disease within a population; alternatively, the appearance of a higher gene frequency could be related to the migration of individuals already having the deletion. One such migration that has been discussed and that is of interest here is the transition from the Mesolithic to the Neolithic. Traditionally, this is connected to a change in economy from a hunter-gatherer way of life to pastoralism-farming. This change in economy is most often explained by three major themes, of which immigration is one. Subsistence during the Mesolithic was based on hunting and gathering, as we can see in the individuals analysed from Skateholm and Huseby Klev (Liden et al. 2005). This lifestyle continued during the Neolithic for the Pitted Ware culture. Their main economy seems to have been based on maritime hunting and fishing, as seen in the sites studied here: Ire, Visby and Jettbole (Liden 1995). The Funnel Beaker culture is partly differentiated from the GRK by the change in subsistence towards an economy based on agro-pastoralism, and this pattern is clearly visible in the passage graves analysed here: Rossberga and Hjelmars Ror (Liden 1995). In the late Neolithic, agro-pastoralism continued, as seen in the Dragby samples (Roumelis 2002). However, since we only have one individual from whom it was possible to extract DNA dating to the Mesolithic, we cannot draw any conclusions relating to the migration hypothesis. However, the sample allows for testing the frequencies between the two Neolithic cultures, GRK and TRB, and when using Fishers's exact test (p = 0.005), we do find a significant difference. This difference is in itself interesting, in that these cultures represent different economies, and where the "farming culture" has the lower frequency of the deletion. Does this mean that the hunting GRK culture could be regarded as original, and that the TRB were the newcomers? We cannot say. The second explanation for the distribution of the CCR5-A32 gene was connected to a selection process due to a specific disease. It is, however, obvious that the 32bp deletion in the CCR5 gene had spread and reached a relatively high frequency in Scandinavia at least during the Neolithic, and that selective advantage due to the plague is evidently not a likely cause of the present day allele distribution. Previous studies also suggest that this is an unlikely hypothesis, as the short period during which the plague ravaged Europe would not have caused a selection pressure strong enough to alter frequency to any greater extent (Galvani and Slatkin 2003). Consequently, we will have to seek other explanations for the spread of the 32bp deletion in the Mesolithic and thereafter in Scandinavia. Galvani and Slatkin (2003) proposed that the more continuous smallpox mortality that afflicted European children since the origin of the allele could have provided the necessary selective pressure to generate the rise of CCR5-A32 deletion to current frequencies of 10%. Our evidence pushes the dating of the CCR5 32 bp deletion back to around 5000 BC, which supports the suggested date for the deletions first occurrence to more than 5000 years ago (Sabeti et al. 2005). 33 Kerstin Liden, Anna Linderholm, Anders Götherström Site # extract.

Dating the CCR5-A32 bp deletion to the Mesolithic in Sweden and its implications for the Meso/Neo transition Conclusions The CCR5-A32 results indicate that the frequency of 17.1% in our samples corresponds to the frequencies of CCR5-A32 mutation in present-day Sweden. Thus there seems to be no difference in the occurrence of the deletion from the Neolithic and onwards in Sweden. The mutation occurs in two different Neolithic cultures, both the GRK and the TRB, despite differences in subsistence and lifestyle. This indicates that the selective pressure that caused this deletion to evolve had nothing to do with subsistence or way of life. There is also evidence for the mutation having oc-cured in one of the Mesolithic populations, although the sample size is small and no definite conclusions can be drawn from this. The fact that the CCR5-À32 is present during the Mesolithic is interesting in itself, and pushes the date of the first occurrence back to around 5000 BC. -ACKNOWLEDGEMENTS- We thank Birgit Arrhenius, Göran Bratt, Lars Beck-man, Helena Hedelin, Jan Stora, Torbjörn Ahlström, Per Persson, Anders Angerbjörn, Gunilla Eriksson, Annica Olsson, Kjell Persson, for help in different ways, The Laboratory of Molecular Systematics in Stockholm for lab space, and the Swedish Natural Science Research Council and The Royal Swedish Academy of Sciences for funding.

Archaeology and genetics Mark Pluciennik University of Leicester, UK M.Pluciennik@le.ac.uk ABSTRACT - This paper examines the ways in which genetic data have been used to interpret the transition to agriculture in Europe over the past two decades, and the relationship of these interpretations to more strictly archaeological explanations. It is suggested that, until recently, those working within the two disciplines have been using not only different data sets and methodologies, but also working within different disciplinary traditions which have inhibited communication and collaboration, and the production of a genuinely integrated field of 'archaeogenetics'. IZVLEČEK - V članku analiziramo pristope, ki so v zadnjih dveh desetletjih uporabljali genetske podatke pri interpretaciji prehoda na poljedelstvo v Evropi ter odnos med temi interpretacijami in striktno arheološkimi razlagami. Ocenjujemo, da so raziskovalci v okviru teh dveh disciplin do nedavna uporabljali različne metodologije in serije podatkov ter delali znotraj različnih raziskovalnih tradicij. To je preprečevalo komunikacijo in sodelovanje ter izdelavo pristno integriranega področja 'ar-heogenetike'. KEY WORDS - Genetics; archaeology; Neolithic; rhetoric Introduction Archaeology has often had a strange and occasionally fraught relationship to science; the discipline is often described as straddling the humanities-science divide, and many of us would not be averse to being described as social scientists. Nevertheless, on occasions and especially, perhaps, in Anglo-American archaeology, academics have sometimes tried to urge archaeological practice more forcefully in the direction of harder science, or alternatively and perhaps in reaction towards the 'softer' humanities. Such arguments have tended to be about philosophical and epistemological positions rather than methodological ones, and have their basis in the nineteenth century. For example, in 1858 Johann Droysen proposed that there were three types of systematic knowledge: the speculative, which related to the kind of knowledge produced by philosophy and theology; the mathematical or physical, grounded in logic and in empirical facts; and the historical. He suggested that these three realms of knowledge had what he called three 'essences' or characteristics: respectively, to know (Wissen), to explain (Erklären) and to understand (Verstehen). The last two roughly equated respectively to the 'hard sciences' - physics, chemistry, biology and so forth - and the 'humanities'. The social sciences including archaeology can, however, be seen to partake of both 'essences'. Archaeology is an unusual discipline in drawing on both types of 'knowledge' and their associated theories more or less equally and in an internally-integrated manner; other disciplines such as geography, for example, have ended up with divisions which more or less equate to these distinctions, with physical and human geography. The history of archaeological theory and indeed its disciplinary culture and even status can thus in part be characterised as leaning towards one side or the other - towards science or the humanities for its inspiration. 39 Mark Pluciennik As usual, though, the picture was and is more complicated: archaeologists are perhaps better described as theoretical magpies. Archaeologists of any persuasion routinely use statistical analysis and scientifically obtained environmental data, for example. In the Anglo-American world, 'scientific' New and pro-cessual archaeologists were interested in social and cultural phenomena, and not just in explaining energy extraction from the environment. Scientific methodologies and procedures and data are important to all of us; the necessity to be something of a jack-of-all-trades, having to be aware of isotope analysis and cultural theory, Bayesian modelling and social anthropology, is what makes the discipline particularly challenging. It has therefore been interesting to observe disciplinary reactions when a new and undoubtedly scientific technique from a hitherto unrelated discipline, which I shall here call 'genetics', came to impinge on archaeological understandings of the past. This seems to have been a particularly divisive area, particularly in addressing the question of the Meso-lithic-Neolithic transition, primarily in Europe, and which I shall use as my case study in this paper. By and large, archaeologists were hostile to the outcomes and apparent implications of relevant genetic research: very few archaeologists embraced the genetic data (and controversial 'evidence' from linguistics) with fervour. Equally, geneticists often appeared as though they considered archaeological data irrelevant for studying the prehistoric past. Why should this be? After all, this particular relationship started as collaboration. In this paper I will mainly examine some of the rhetoric and practices associated with this debate as a way of considering whether there are, despite archaeology's hybrid position, fundamentally different disciplinary cultures involved. I shall conclude by looking at some of the implications for methodologies - not for genetics or molecular biology, which I am totally unqualified to offer - but rather ways of collaboration and means of approach. Genetics and archaeology Thirty five years ago (and subsequently elaborated in detail), Albert Ammerman and Luigi-Luca Cavalli-Sforza (1971; 1973; 1984) presented an interesting idea relating to a potential new source of evidence about the spread of farming in Europe. Discussing the apparent rate of spread of the Neolithic, and explaining this through an initially exogenous population expansion associated with early farming in Eu- rope, they mentioned the 'possible genetic implications of the model'. "The population wave of advance accompanying the spread of early farming should be reflected, if this [demic diffusion] explanation is the correct one, in the genetic compositions of the resulting populations." (Ammerman and Cavalli-Sforza 1971.687) This was - and is - a powerful idea. Since that time there has been a huge amount of genetic data and analysis published which is often stimulating, which has undoubtedly raised new questions and perhaps offered new insights, through looking not just at overall genetic frequencies of classical markers such as blood proteins, but subsequently also at different regions and sites within the genome, and suggesting genetic histories - phylogenetics - and putative dates for mutations and haplotypes, and consequently histories of haplogroups; and of differences between female-inherited (mtDNA) and male-inherited (Y-chromosome) genetic material, for example. For the purposes of this paper, though, it is worth noting that the question as posed initially by Ammerman and Cavalli-Sforza was primarily an archaeological question: genetic information, it is suggested, may be able to illuminate the process of transition, given certain primarily demographic conditions. The demographic modelling was in part based on ethnographic data relating to hunter-gatherer and small-scale farming societies. Since then, and especially since the 1990s, the discipline of what some call 'archaeogenetics' (Renfrew 2000.3) has seen the production of large numbers of datasets and numerous interpretations in relation to the transition to and spread of farming, especially in Europe, as well as much evidence related to migratory population movement elsewhere - Polynesia and the Americas in particular (see e.g. Jones et al. 1999; Renfrew and Boyle 2000). So far, these datasets have been derived primarily from modern populations, and the information explored in terms of their phylogenies - the genetic histories - and modern spatial distribution. Ancient DNA, which would appear to offer much more specific information from individuals and groups of individuals who can be placed, culturally-situated and dated archaeologically, is rarely sought, mainly because of the potential problems of identifying contamination (but see e.g. Chandler et al. 2005; Haak et al. 2005). This is not the place to explore the use (and abuse) of such data in detail: but see Mirza and Dungworth 1995; Fix 40 Clash of cultures? Archaeology and genetics 1996; Pluciennik 1996, Sims-Williams 1998; Mac-Eachern 2000; Zvelebil 2000; Bandelt et al. 2002). There has been a persistent and major problem of the conflation of genetic, linguistic and cultural 'entities' and (pseudo-)archaeology, with the assumption that these forms of biology, culture and identity almost inevitably go together (see Moore 1994; Terrell and Stewart 1996), at least until 'modern' times. I would suggest that archaeologists already 'knew', and certainly by the 1980s, that the process of the Mesolithic-Neolithic transition in Europe was complex socially, culturally and therefore almost certainly, biologically. However, one gets little sense of this from looking at the genetic literature, until very recently. And even here the methodology seems, to many archaeologists, rather upside-down. 'We would argue that it would be worthwhile to turn the scientific procedure around', argued Pinhasi et al. (2000. 55). That is, the apparent injunction to start with a simple model - even though obviously, archaeologi-cally-speaking, wrong - is presented as a methodological necessity. In the case examined here, it is that the spread of farming represents either population expansion by genetically-distinct farmers, or the adoption of farming by genetically distinct foragers. To be fair, a few later publications - led by archaeologists - have asked whether the genetic and other biological signatures supported archaeological interpretations on a regional scale (e.g. Lalueza Fox 1996; Jackes et al. 1997; Pinhasi and Pluciennik 2004; Chandler et al. 2005). Another and arguably more productive approach would be, for example, to model the relevant genetic histories in terms of archaeological understandings of the processes involved (in the plural!), and at least ask what kinds of genetic outcomes we might expect. Yet after 20 and more years of research, this kind of question is apparently only now beginning to be asked. It is these kinds of intellectual propensities and resistances which suggest that at least some of the tensions between 'archaeological' and 'genetic' explanations of the Meso-lithic-Neolithic transition are best explained as matters of disciplinary preferences and traditions of thought and practice; that is, of culture. The great divide One of the striking aspects of the relevant literature is that for a very long time the 'archaeology' was swept aside and the debate was very largely driven by the genetic data - and hence, de facto, by the geneticists. This was so even though we had here a po- tentially powerful new set of techniques for saying something about the past, although exactly what they 'say' certainly is not yet clear. Thus in relation to the Neolithic in Europe (the area where many of the best data sets tended to come from), the approach in the publications basically became a question of supporting (or much more rarely disagreeing with) this model of 'demic diffusion'. Even in a recent review, this is still how the question is characterised: 'The primary issue remains whether agriculture spread by contact or by farmers moving into Europe' (Armelagos and Harper 2005.109). So powerful was this drive that some archaeologists, too, decided that the 'truths' of genetics were more plausible than those suggested by the archaeology. The debate became strongly polarised: in general, geneticists (and a few others) accepted the 'fact' of demic diffusion and published evidence which apparently supported it. Meanwhile, many archaeologists had been moving just as strongly away from demic diffusion models and were increasingly arguing for the Mesolithic-Neolithic transition as a highly variable socio-cultural phenomenon (including demographic and other biological processes) on the regional, let alone the continental scale (Zvelebil 1986a; Price 2000). But they were not - and I include myself here - engaging with geneticists through collaboration and joint publication; instead, there were critical papers and conference sessions in which archaeologists were primarily talking to archaeologists, in the same way that geneticists were primarily writing for and speaking to other geneticists. Thus there were a series of papers, referred to above, critical of genetic interpretations which by and large ignored the archaeology and continued to confuse and conflate biological constructs - genetic histories - with social entities, including linguistic and ethnic groups and names. This polarisation is seen in Table 1. Here some papers by geneticists and published primarily in journals in that discipline in the 1980's and 1990's are summarised. The fact that these are generally multi-authored is, of course, itself an aspect of disciplinary culture: the convention is for entire laboratory teams to be named as authors. More interesting, perhaps, is the fact that archaeologists were rarely involved in producing these papers: their 'contribution' was limited to a very few items (and those often out of date) cited in the bibliographies. There were notable exceptions: I would single out Martin Richards (see this volume), and also note that where archaeologists were involved (such as Colin Renfrew) appropriate archaeological and other citations were frequent, various and up-to-date. Nevertheless, the widespread 4i Mark Pluciennik Authors Date Geneticists Archaeologists (linguists) Subject Archaeology references (n) Torroni et al. 1998a 11 - Late Paleolithic re-colonization 1990 (1) Wilkinson-Herbots et al. 1996 4 - Late Palaeolithic re-colonization 1986> 1995 (2) Sajantila et al. 1995 13 Genes & languages 1987, 1988 (2) Torroni et al. 1998b 11 - Late Palaeolithic re-colonization 1990 (1) Sokal & Menozzi 1982 2 - Neolithic diffusion ^71 1973 (2) Richards et al. 1996 10 - Palaeolithic & Neolithic diffusion 1983-1995 (10) Semino et al. 1996 5 - Neolithic diffusion 1889, 1943, 1989 (4) Pult et al 1994 6 - Modern humans in Europe - Rendine et al. 1986 3 - Neolithic diffusion 1953-1984 (8) Barbujani et al. 1994 3 1 Neolithic diffusion 1971-1992 (17) plus linguistics Jones 1991 1 - Neolithic diffusion - Sokal et al. 1991 3 - Neolithic diffusion 1953-1991 (7) Tab. 1. problem amongst geneticists of their ignorance of socio-cultural processes and archaeological interpretations and debates - or perhaps the failure to see their possible relevance - is best epitomised by the astonishing paper by Robert Sokal and colleagues. Rather than seeking archaeological advice, he preferred to use a 'European ethno-history database, developed in our laboratory' which 'documents the known locations and movements of 891 ethnic units over the last 4000 years' (Sokal et al. 1993.56). The database purported to 'list the name of a "gens" or tribe (or that of an archaeological horizon in the case of prehistoric records...)' (Sokal et al. 199357). Thus, even though Renfrew (2000.3) claimed that the new discipline of archaeogenetics involved 'the study of the human past using the techniques of molecular genetics', it tended to be a very partial view. Renfrew continued: 'In practice this is likely to involve the collaboration of molecular geneticists with archaeologists, anthropologists, historical linguists and climatalogists'. But so far and despite the inte-grative work of Renfrew and other grand theorists such as Peter Bellwood (Bellwood 2001; 2004; Bellwood and Renfrew 2002; Renfrew 1992; 1996; 1997) and indeed Cavalli-Sforza himself (1996), such collaboration has not been substantiated, at least in terms of joint authorship, with rare exceptions (e.g. Barbujani et al. 1994). Indeed, even in the volume Archaeogenetics itself, the division between papers by archaeologists, and papers by geneticists, is as strong as elsewhere. Many other similar papers have been published, of course: those summarised in Table 1 are merely a selection of those claiming to deal explicitly with an archaeological issue, namely the transition to farm- ing in Europe, or occasionally, the late Palaeolithic recolonisation of post-Last Glacial Maximum northern Europe. These latter are included because they often discuss the 'Mesolithic' and 'Neolithic' input as compared with 'Palaeolithic' contributions to gene pools. Also excluded are those papers which only allude to possible 'prehistoric scenarios' in passing, and are primarily methodological or papers descriptive of genetic data, and for which the audience will be other geneticists. Other papers not included here examine the supposed relationships between genes and languages. While one could show a similar table for relevant papers written by archaeologists, it would not be so informative. Inevitably, there were up-to-date references for genetics papers (because that is what they were criticising), but (apart from those of Am-merman and Cavalli-Sforza) there were virtually no joint cross-disciplinary papers in the 1980s and very few in the 1990s, but more in the last five years and other evidence of efforts to bring archaeologists and geneticists together (e.g. Bentley et al 2003; ESF 2004; Gamble et al. 2005; this volume). Apart from the methodological and epistemological facts of the matter, we should also be interested in this as a socio-political phenomenon. Why did the 'debate' unfold in the way that it did? Where are we now? And where we might realistically look for synergies between archaeology and genetics? Rhetoric and politics There are other contexts for this, which perhaps also suggests that other more subtle socio-politics are playing a role here. First of all, we can note that of the broadest set being examined, the most high profile archaeogenetics papers and the greatest volume 42 Clash of cultures? Archaeology and genetics of work related to either big issues (the origins of modern humans and Neanderthal DNA; origins and spread of agriculture; origins of contemporary peoples such as Polynesians or Native Americans): apparently foundational episodes, rather than the implications of day-to-day demographics and genetic exchange - sex - across or within group boundaries. Overall there are three major groups of relevant papers in order of volume: O Papers describing the structure of genetic material and distributions both phylogenetically and geographically: this is basically about genetic data production; © Papers dealing with methodologies and model building; © Papers dealing with histories: these tend to be stated in terms of 'Neolithic', or 'Indo-European' contributions; only recently have geneticists started to model admixtures. The emphasis in the last group seems to me to demonstrate the well-known prevalence of historical questions dealing with origins - what led to 'us' (e.g. Piazza 1993). Were this archaeology, one might argue that this focus also relates to the continued influence of stadial social evolution, and hence on apparent moments of transition understood as radical change. In archaeology these biases have at least been considered and critiqued, while geneticists, in a different tradition, typically, are not necessarily au fait, or used to dealing with such political and critical issues of structures of thought and narratives. However, it seems that within genetic studies the more likely explanation is that, to begin with, at least, the methodological need to distinguish between populations led to and maintained the focus on the 'new' or distinctive, genetically speaking. Other factors In the late 1980s Ammerman (1989) and Zvelebil (1989) exchanged views on how to approach the Mesolithic-Neolithic transition in Europe, and what was structuring those views. Ammerman suggested, broadly, that the bias towards and interest in processes of cultural diffusion and adoption of Neolithic traits by indigenous forager populations á la Zvele-bil was a result of post-colonial guilt within Europe (see also Keeley 1992). Whatever one's view about the influence of politics on archaeological interpretations, no such doubts assailed many looking at demic diffusion from the genetic point of view. The important thing about the Mesolithic-Neolithic tran- sition was the incoming, novel populations: the interest was in the 'contribution' of farmers, a bias which has been noted in the construction of modern European identities (Zvelebil 1996). Thus presentations tended to be couched in terms of Neolithic (or Indo-European) immigrants, rather than of mixing, or hybridism. This was so when estimates of the 'Neolithic contribution' through a 'wave of advance' were higher than the consensus is now - in Cavalli-Sforza et al's famous map obtained from Principal Components Analysis it was suggested that the Neolithic contribution to the gene pool might be of the order of 28% (Cavalli-Sforza etal. 1994.291). Subsequently revised downwards, most genetic models now suggest a 'Neolithic' genetic contribution of perhaps 15%-20% on the continental scale (Richards 2003; but see Barbujani and Dupanloup 2002; Chikhi 2002). This initial estimate was in marked contrast to archaeological interests and, indeed, models developed over the same period (e.g. Zvelebil 1986b; Gro-nenborn 1990; 1999; Skeates 1994; Zilhao 1993), all of which suggest marked variation in the nature of 'Neolithic' distribution, although authors do not necessarily agree on the form that it took). Nevertheless, even on the the basis of the earlier figure it is clear that the overall 'Neolithic' contribution was a minority, regardless of whether other 'contributions' derived from earlier or later demographic and genetic events and processes. It is less certain whence this apparent bias towards farmers derives. One argument would be that from a genetic point of view researchers were, as a matter of practical methodology, necessarily looking for markers of change (understood as some form of colonisation), and that the underlying substrate (equated with indigenous and relatively static Mesolithic populations) was simply less interesting. Work on mtDNA, in fact, subsequently raised the question of the genetic impact of late Palaeolithic re-colonisation. Nevertheless, it is interesting to note (assuming the 20% figure is roughly correct) that, inadvertently or not, such a focus on the impact of the 'new' is a continuation of long-established culture historical interpretations: the role and identification of colonisers and invaders assumes priority over processes of cultural hybridism and mixing. More generally, for archaeologists, periods of non-migration or colonization (or demographic or other forms of stability) are just as interesting as any other. The present scenario It seems to me that in relation to the Mesolithic-Neo-lithic transition, the way that this source of informa- 43 Mark Pluciennik tion has been utilised has not been a happy one: there appear to have been a series of lost opportunities especially throughout the 1990s. Unfortunately, I am unable to engage in debates about the best way to model and (re)construct phylogenies, and the relationship they have to demographic processes. But it is noticeable that from the 1980s onwards, the consensus in archaeology about the Mesolithic-Neo-lithic transition has been that this process, or rather this set of processes, was highly variable in time, space, tempo and nature; and that demic diffusion as originally defined was probably always only part of the answer in specific locales. Thus it is arguable that archaeologists and others should collaborate in modelling the production of genetic diversity relating to this period by • Identifying relevant demographic, biological, social, and cultural processes on a variety of regional and temporal scales; • Identifying potential variability in parameters; • Considering the problem of equifinality (and lack of resolution in genetic data); • Discussing the limits of resolution, and identifying appropriate techniques and modelling; • Modelling potential genetic outcomes. It is surprising that no-one was doing at an earlier stage in the development of 'archaeogenetics' what Ammerman and Cavalli-Sforza set out to do in their initial model: namely, this is what the archaeology (in their case, the radiocarbon dates) suggests might be happening in this period; these are the kinds of cultural (and demographic, and social, and biological) processes: what might the genetic outcomes of these kinds of small-scale, regionally variable biological and demographic processes be like? A similar plea was made by three archaeologists (or physical anthropologists) at the conference from which the Renfrew and Boyle Archaeogenetics volume derived: "Instead of generating historical hypotheses from the present genetic patterns, and trying to fit the archaeological record onto these, it would be useful to build hypotheses from the actual record of the past in time and space, which could then be tested with genetic data." (Pinhasi et al. 2000.55) But although many of us were critical of many of the assumptions associated with the wave of advance -or at least its continent-wide application - none of us went on (or was able to) develop [in collaboration!] the kinds of models that were actually requi- red to make 'sense' of much of the genetic data. Zve-lebil (2000) described the variety of relevant potential processes and problems with genetic approaches, but could not be expected to deal with the genetic aspects of population modelling. Perhaps one reason for this lack of explanation (or interpretation) of the genetic data as the result of complex processes is simply the difficulty of conceiving and producing such models. It is also part of a wider disciplinary cultural difference: the use of binary logic to begin an explanation or modelling process (either p or not-p; either demic diffusion or adoption). But even though much has changed in attitude at least over the last five years or so, the underlying problems remain. For example: Currat and Excoffier (2005) examine some of the reasons for contradictory signals from different types or sources of genetic data (e.g. Y chromosomes, mtDNA, 'classical' markers). They build a model which simulates various scenarios of genetic exchange between indigenous 'Palaeolithic' and exogenous 'Neolithic' populations. But this, archaeologically well-informed, paper also notes: "Our simulations were performed in a homogenous environment with g [a measure of forager-farmer genetic interaction] identical in every deme, regardless of its location. While this assumption may seem unrealistic at a regional scale, it is quite reasonable at a continental scale... It would be interesting to test... the influence of some heterogeneity of the migration wave, and to incorporate, with considerable additional work and computer power, more realism in the simulation... It, however, appears necessary to understand the genetic signature expected under a relatively simple demographic scenario, before considering more complex ones" (Currat & Excoffier 2005.684) We find very similar phrases used by Dupanloup et al. (2004), but again working on the effects of 'admixture' on a continental scale: "In the future, it will be important to incorporate detailed archaeological information into the population models, so that the assumptions will become both more complicated and more realistic." (Dupanloup et al. 2004.1370) It is a rather sad commentary on academic communication that it appears to have taken some twenty years to reach this conclusion. 44 Clash of cultures? Archaeology and genetics Discussion This raises a whole series of other questions. One of which is: even if such detailed archaeological information were incorporated, what effect might it have on our archaeological interpretations? That in turn suggests another: what is it that we, as archaeologists, are interested in, what kinds of phenomena? Clearly, demographic processes per se are only a part of the answer - it is cultural and social process (which, of course, incorporates demographic and other biological factors and outcomes). There remain, as described above, marked cultural differences between 'sciences'; as a social science looking at and interested in primarily social phenomena, archaeology always deals with the already complex; to apply 'harder' science criteria to cultural processes is often unhelpfully reductionist. "When historians look back on the 21st century, they may well conclude that this was the moment when the biological and medical sciences finally began to appreciate the multi-layered complexity of all living things... As Francis Crick put it: "While Occam's Razor is a useful tool in the physical sciences, it can be a very dangerous implement in biology. It is thus very rash to use simplicity and elegance as a guide in biological research." (Weatherall 2006) Archaeology is very much a mixture of disciplines, methods, techniques and approaches. Pinhasi & Plu-ciennik (2004) also examined the mesolithic-neoli-thic transition in southern Europe using relatively 'hard' data (skeletal morphometrics), which is partly related to genotypes and gene frequencies. However, we suggested that such data are rather another point of triangulation in the complex debate about some aspects of the demographic and cultural processes in this period of prehistory. It is a necessarily woolly picture. In that paper we wrote: "Neither skeletal, nor genetic, nor archaeological [nor linguistic] data alone will provide "solutions" to questions about the nature of the Mesolithic-Neo-lithic transition. Different data sets address a variety of processes at different scales and chronological and geographical resolutions." (Pinhasi &Pluciennik 2004.74) What does seem to tell us much more of interest as archaeologists is when we can start talking with some degree of certainty about regional and local processes, whether through excavation, dating, or combinations of such things as genetic and skeletal isotope and archaeological information (e.g. Bentley et al. 2003). This is because larger continental or even global phenomena are emergent from and dependent on the local. The global usually does not necessarily tell us that much of interest on its own, although it may also give us a framework; we need at least to tack back and forth between the local and 'global' to answer the kinds of questions about cultural shift and social change with which many of us are concerned. Genuine archaeogenetics must be informed by the archaeological, just as the archaeological should draw on the genetic. There remain problems of chronological resolution and scale. For much of prehistory we are often constrained to discuss general, structural, relatively long-term change (in settlement patterns, in modes of exploitation, in patterns of material culture, in belief systems as evidenced in burial practices, and so on); however, we can and often do illuminate these structural shifts by tightly-constrained contexts (in duration and location) which act as snapshots of practices at a particular place and time. We have the macro-scale and we have the micro-scale; what archaeology often finds difficult is the meso-scale, at which much social change could be argued to manifest itself most clearly. When, however, we look at the dating of events - demographic or genetic - drawing on strictly genetic data, we are even less likely to be able to discuss meaningfully events or processes in socio-cultural terms, simply because the standard deviation associated with such 'molecular clocks' is much greater even than that associated with radiometric dating. And in any event, even if, say, mutations can be dated, it does not necessarily help an understanding of the subsequent process of geographical and biological dispersal on the kinds of scales with which we are concerned for socio-cultural processes. Similar issues arise from the lack of spatial resolution. I would suggest that it is still the case that we cannot discuss prehistoric demographic 'events' in a meaningful social scientific (rather than biological) way, certainly not from modern genetic data. The kinds of resolution which might help us as archaeologists to discuss the socio-cultural and biological processes in the past might be available from palaeogenetic data (especially if allied with other techniques such as isotope analysis), but so far there are simply insufficient surviving samples of old DNA, and I suspect that (archaeo)geneticsts have also found it easier and more profitable in the academic sense to work 45 Mark Pluciennik through the much more accessible modern data. This perhaps suggests that we have sometimes asked the wrong questions, and that we should be able to use this new data source in more illuminating ways than simply in terms of the old dichotomies of colonisation and adoption in which both geneticists and some archaeologists seem to be entrapped. The potential use of genetic data in conjunction with archaeological, and in this case other palaeoclimatic evidence is admirably demonstrated by Gamble et al. (2005) discussing the archaeology of Late Glacial (re)colonization. Although the methodologies will not be the same for the early Holocene and the Meso-lithic-Neolithic transition, there are equally relevant 'databases' which can be used to investigate questions of population history and human and cultural dispersals and shifts. Conclusion There has been a welcome shift from the description and exploration of genetic data sets (e.g. genetic structure of Europe) to interpretations of 'real world' history. But this is still a limited focus, from an archaeologist's point of view, on demography and biological history and structure, which is perfectly understandable, and also interesting and relevant, but also only part of the kinds of histories we are interested in. For various reasons, the intellectual investment by some (archaeologists and geneticists) in modelling or explaining 'the Neolithic' as demic diffusion has proved a hindrance. As Gamble et al. note (2005.218): " When the genetic data were first suggested to support Late Glacial expansions in the mid-1990s, the dominant view in population genetics was that the major signal was Neolithic. This came as something of a surprise and seems to have been resisted by some ever since." This paper has been an attempt to understand why genetic data have been presented in the way that they have in the debate on the Mesolithic-Neolithic transition; and to discuss some problems of cross-disciplinary communication and the effects of different disciplinary aims and cultures. Is it just that genetics is too large, too self-sufficient, too complex a field? Or is it that 'archaeogenetics' was initially an interesting sideline to most geneticists, and the historical (or socio-cultural) side was simply not worth the intellectual investment? Or is it that (anthropologically-trained) archaeologists have in the main found it difficult to engage with the data and impli- cations of the methodologies - such as the modelling of population genetics and molecular biology -at the level of detail required? If geneticists may have been disappointed in the inability of most archaeologists to be able to engage at the technical/methodological level, on the archaeological side such frustration and even resentment was compounded by the lack of consultation from geneticists and the minimal or dated use of archaeological data, publications and relevant theory. Equally, geneticists may have found the comparatively slow productivity of archaeologists and relevant archaeological data irritating: anecdotally, Cavalli-Sforza was said to want to stop working with archaeologists because they took so long to produce results, as compared with genetic analyses. National and international disciplinary expectations (surely compounded by exercises such as the UK government's system of measuring and rewarding research output, or similar systems in other countries such as citation counts), really do structure different norms of activity, especially across very different disciplines, and what it is intellectually worth 'investing' in. Such barriers are likely to be particularly high at the inception of a new and initially unrelated technique/approach. Nevertheless, we have to find ways of not just talking to, but communicating with each other in meaningful ways in which we can all start to understand the challenges and limitations as well as possibilities of new methods and ideas. Genetics is, of course, also a continually changing field, with new data and new techniques continually being produced, explored and refined. We certainly have not reached the limit of what genetics can tell us about some past processes. Such studies also often act to stimulate new archaeological approaches and interpretations, or suggest boundaries to existing explanations, and this will continue to happen. Archaeology is an especially multi-disciplinary practice; genetics will for the foreseeable future be one of a battery of techniques, approaches, ideas and datasets that we will incorporate into our interpretations. 46 Clash of cultures?

However, there sometimes seems to be a degree of disjunction between the patterns revealed by genetic analysis and the increasingly complex social and economic processes that archaeology is starting to identify. In this contribution, I point to the multiplicity of identities, subsistence regimes and patterns of social interaction involved in the introduction of the Neolithic into northern and western Europe, and consider the implications for genetic research. IZVLEČEK - Genetske informacije so v zadnjih štirih desetletjih igrale pomembno vlogo pri študiju mezolitsko-neolitske tranzicije v Evropi. Včasih se zdi, da prihaja do odstopanja med vzorci, ki jih razkrivajo genetske analize in med kompleksnimi socialnimi in ekonomskimi procesi, ki jih proučuje arheologija. V tem prispevku poudarjam mnogoterost identitet, prehrambenih režimov in vzorcev socialne interakcije, ki so bili vpleteni v uvajanje neolitika v severni in zahodni Evropo in ocenim, kakšne so implikacije za genetske raziskave. KEY WORDS - archaeogenetics; demic diffusion; agency; frontiers; cultural hybridity Scales and units of analysis Over the past forty years, a fascinating dialogue has been developing between archaeology and genetics, specifically in relation to the question of the dispersal of domesticated plants and animals into Europe and its relationship with the movements of human populations. This debate has often been marked by a degree of mutual confusion, owing largely to the different temporal and spatial scales at which the two disciplines operate, and the different questions that they address (Brown and Pluciennik 2001. 101). While genetics generally concerns itself with the global or continental scale, archaeology is often more focused on the regional and the local, with the result that phenomena that are described at different levels of magnitude may appear to contradict each other. Some common ground is now beginning to emerge, but from an archaeological point of view it is especially interesting to ask whether the fine- grained patterns that we think we can discern in the evidence can be accommodated by the broader sweep of the genetic information, or whether there is a degree of dissonance between the two, whose investigation might prove fruitful. We are indebted to Albert Ammerman and Luca Ca-valli-Sforza (1971; 1973) for initially stimulating debate with their discussion of the expansion of agriculture into Europe through demic diffusion, developed in the first instance in relation to radiocarbon dates from Neolithic sites, and later used as a means of explaining the distribution of genetic markers across the continent. The model of farming communities gradually expanding as their population rose, fuelled by the productivity and reliability of their subsistence base was explicitly differentiated from migrationary arguments, in which communi- 51 Julian Thomas ties are imagined to leave one area in order to settle in another (Cavalli-Sforza 2002.82; Bellwood 2002.17). None the less, subsequent debate has generally been framed in terms of the contrast between demic and cultural diffusion; the physical spread of farming societies versus the transmission and adoption of Neolithic innovations amongst indigenous hunting societies. While Ammerman and Cavalli-Sforza have been careful to acknowledge the diversity of the processes that might have been involved in the Neolithic transition in Europe, and to recognise a role for indigenous peoples in that process, some of the geneticists who have followed in their wake have tended toward a more categorical view (Cavalli-Sforza 2003.303). Recent publications by Barbujani and Dupanloup (2002), and by Chikhi (2002), seem to imply that demic and cultural diffusion are polar opposites, and that if the presence of substantial Near Eastern genetic material attributable to a post-Palaeolithic horizon can be identified in Europe, the Neolithic must have spread into the continent primarily, or exclusively, by population movement. At a philosophical level, many of the difficulties that we encounter in trying to reconcile archaeological and genetic evidence arise from the ways in which we conceptualise past human communities and populations. Here, archaeology must take much of the blame for developing and perpetuating the image of human groups as self-contained and bounded entities. It is instructive to remember that Gordon Childe formalised the notion of the archaeological culture precisely in the context of his study of the early agricultural societies of south-east and central Europe, in work that led up to the publication of The Dawn of European Civilisation (Childe 1925) and The Danube in Prehistory (Childe 1929). While Childe was adamant that culture and race did not coincide (1950.1), and even though he was an enthusiastic proponent of cultural diffusion, he none the less instituted the expectation that a variety of different aspects of human identity should be congruent, so that definable distributions or assemblages of artefacts could be identified as the material signatures of 'peoples' who existed in the past (Jones 1997.17). I would argue that this is an understanding that arises from the modern experience of living within the nation-state, where political, ethnic, linguistic and expressive entities are generally bounded at the same level. This, then, grounds our expectation that in prehistory we should be dealing with neatly bounded social units (Thomas2004a.Ch. 5). Of course, such an emphasis on bounded and inter- nally homogeneous social wholes was by no means exclusive to culture-historic archaeology: it was also a hallmark of much processual archaeology (Brum-fiel 1992). Indigenism and evolutionism One of the most innovative and attractive aspects of Ammerman and Cavalli-Sforza's work was that it challenged both the culture-historic image of bounded ethnic groups in prehistory, and the processual vision of autonomous communities in parallel evolution, influenced only by environmental selective pressures. As they point out, their initial papers were written at the high point of anti-diffusionist sentiment in archaeology, the time of 'the autonomy of the south-east European copper age' and of 'Wes-sex without Mycenae' (Cavalli-Sforza 2003.299). More recently, Albert Ammerman has explicitly juxtaposed the internationalist aspect of a perspective based on demic diffusion, spreading agriculture across the continent in a wave of advance, with what he calls 'indigenism' (Ammerman 2003.4). Indige-nism holds not only that each society is independent and autonomous, but also that its development can be attributed to internal processes, or to its specific relationship to its environment. As such it chimes with the culture-historic image of the bounded cultural unit, and shares its affinity with nationalistic approaches, which often hark back to a mythical golden age of ethnic homogeneity (Gellner 1983.57). Each nation has its own tribal ancestors, who were responsible for their own independent domestications, and their own rise to statehood. So at a time of heightened friction between the western and Islamic worlds, Ammerman is absolutely correct to emphasise the importance of a Near Eastern contribution to the European genetic inheritance. But on the other hand, there is the equal and opposite danger of a crude social evolutionism which presents hunters and farmers as representatives of different stages of cultural development (Boric 2005; Warren 2005; etc.). While demic diffusion is a population model, the peril is of casting hunters and gatherers as passive and powerless in the face of the oncoming Neolithic steamroller, while the farmers are active and dynamic, even if only in demographic terms (a position apparently adopted by Rowley-Conwy 2004.97). Mesolithic populations are thus understood as being 'absorbed', 'incorporated' or 'recruited'. Here again, we are faced with a problem of scale, for while there is a virtue in describing and explaining a pattern at a pan-European level, it 52 Gene-flows and social processes> the potential of genetics and archaeology leaves little space for any consideration of agency and contingency: outcomes that could have been otherwise, and decisions made in the context of inherited historical conditions. So the fate of hunting and gathering groups appears determined and unavoidable. Similarly, by discussing the change from Mesolithic to Neolithic at a continental scale, such models run the risk of relying on stereotypical and over-generalised models of hunters and farmers. Yet as we are well aware, prehistoric Europe contained colossal variation, between mobile and sedentary hunter-fisher-gatherers, and between tell-based, longhouse and broad-spectrum forms of the Neolithic (Zvelebil 2004.45). It may be that in the near future the questions that genetic information will be able to help us unravel are ones concerned with the kinds of interactions that took place between these diverse communities. Of course, most authorities now maintain that the Neolithic transition in Europe involved some combination of population movement and acculturation, as in the framework that Marek Zvelebil describes as 'integrationism' (2002.397). Zvelebil suggests that we should imagine a mosaic of different processes, ranging from demic diffusion to leap-frog colonisation, frontier mobility, contact and exchange. I would very much concur with him, but would wish to add a further element to the argument. Zvelebil described a series of different mechanisms by which agro-pastoral farming expanded. I would like to question whether it was necessarily the same thing that was expanding throughout, or whether the Neolithic did not undergo a series of fundamental transformations in the course of its translocation (see, for example, Arias 1999.445). The key question is whether there Fig. 1. Synthetic map of the first principal component of variation in 95 classical genetic markers (from Cavalli-Sforza et. al. 1994, copyright Princeton University Press). was a single, constant causal motor for change throughout, such as population growth. I am inclined to doubt this. While in some areas a strong argument can be made for density-driven expansion (cf. Van Andel and Runnels 1995.498), in others it may be that processes were at work to which agriculture was no more than incidental. That is to say, in some parts of Europe the Neolithic may have represented as much an identity process as an economic package. The indigenous component One of the original reasons why the demic diffusion model was considered pertinent to the spread of the Neolithic was that the process was evidently so slow, apparently progressing at around 1.1 kilometers per year over a period of more than two and a half millennia (Ammerman and Cavalli-Sforza 1971.684). By contrast, the cultural transmission of innovations might be expected to have proceeded much faster. But again, this neglects the agency of hunter-gatherers, who appear to have resisted the adoption of agriculture under some circumstances. In order to spread from one community to another, a cultural innovation needs to confer some perceived advantage on the recipient. Agriculture is somewhat ambivalent in this respect: it brings the advantages of higher yield and lower risk, but it might easily be recognised as corrosive of a hunter-gatherer way of life in restricting mobility and personal autonomy, imposing greater labour investment, and transforming property relations. There is certainly good ethnographic evidence of communities resisting economic and technological change for social and cultural reasons (e.g. MacCormack 1978). Now, of course, the first principal component of protein genetic markers shows a gradient across Europe, from south-east to north-west (Fig. 1), and Cavalli-Sforza explains this in terms of the combination of demic diffusion and recruitment or acculturation, so that as the wave of advance swept westwards the expanding Neolithic population would have been characterised by a greater and greater proportion of indigenous genes (Cavalli-Sforza 2002.82). At the peripheries, Neolithic people would have been largely 'Mesolithic' in genetic terms, and there appears to be a level of agreement between classical markers, mitochondrial DNA 53 Julian Thomas and the Y-chromosome in suggesting roughly a 20% Near Eastern Neolithic contribution to the overall European gene pool (Underhill 2002; Richards 2003). However, this is another instance in which the broad picture of human genetics and the fine grain of archaeology rub up against one another, because for a specialist in the study of the British Neolithic the critical issue is that of what transpired when these population processes washed up against the Atlantic façade. At this point the Near Eastern genetic inheritance becomes so etiolated as to be virtually invisible. Neither classical markers nor Y-chromosomes detect any 'Neolithic' presence in Britain, yet it is of considerable importance to consider what this non-presence represents, and what the processes might have been that gave rise to it. For instance, in proposing a 'staged population interaction' wave of advance, Colin Renfrew (2002.100) argues that a process of demic diffusion and the incorporation of hunter-gatherers might have continued uninterrupted beyond the point where any of the genes of Near Eastern framers were present. Martin Richards, however, indicates that this is not compatible with the mitochondrial DNA evidence (2003.153). On the other hand, there is the suggestion that the classical marker plots represent palimpsests of a series of north-westerly population movements throughout pre- and proto-history, which potentially reduces the impact of Neolithic population movement (Zvelebil 2002.385). Perhaps most interesting is Richards' suggestion that mitochondrial haplogroups J1a and J1b may relate to the very swift dispersals of the Cardial complex and the Linearbandkeramik, at speeds swifter than those predicted from demic diffusion (2004.152; Sykes 2003.323). This is significant because it harmonises both with the idea of the Neolithic transition as a patchwork of diverse population processes, and with that of alternating phases of rapid expansion and prolonged standstill. Some of these episodes of expansion may represent so-called leap-frog colonisation, which I take to be comparable with the modified form of demic diffusion described by Van Andel and Runnels (1995.495) in the earliest Neolithic of Greece: the selective and targeted colonisation of optimal areas. However, we should be wary of assuming that such processes were homogeneous, for while there may be a case for such colonisation in Thessaly, sites like Franchthi Cave may indicate a degree of continuity from Mesolithic to Neolithic, although the extent of this is open to debate (Thissen 2000). Similarly, the very particular locational preferences demonstrated by LBK settlements in central and western Europe, and the extensive unoccupied areas between settlement cells might be indicative of swift expansion into favourable landscapes rather than slow, population-driven movement (Luning 1982.14; Bakels 1982). Recently, Chris Scarre (2002.400) has suggested that the Villeneuve-St-Germain sites of Normandy and the Loire might represent small and dispersed pioneer agricultural groups, who moved into areas of the landscape which complemented those occupied by hunters and gatherers (Fig. 2) (although other authorities argue that the VSG groups were themselves indigenous, and that their somewhat disparate long-houses represent copies of Danubian prototypes: Jeunesse, pers. comm.). Scarre implies that these communities were effectively absorbed by the Mesolithic population, but it is arguable that both groups contributed the subsequent formation of the Cerny group (Cassen 1993; Scarre 1992). Similarly, in east-central Europe, Nowak (2001.582) describes a situation in which distinct enclaves of Neolithic settlement existed in the period between 5600 and 4800 BC. These were migrant Linearbandkeramik groups and their successors, who settled on areas of highly fertile soil, creating 'small islands of farmers in the immense sea of foragers' (Nowak 2001.590) (Fig. 3). In a process analogous to that in western France, it was only when the indigenous communities began to make extensive use of domesticates and Neolithic artefacts that a more culturally homogeneous landscape began to develop, with the formation of the TRB. In Britain, similar arguments have been made concerning the arrival of pioneer Neolithic groups (Sheridan 2000; 2003; 2004, for example), but it is arguable that they are far less convincing. In contrast to the west French or east European examples, there is no clear evidence for the coexistence of Mesolithic communities and Neolithic enclaves, and the start of the Neolithic was abrupt and uniform. Indeed, it is the complete and sudden disappearance of the Me-solithic assemblage in Britain that is the most remarkable aspect of the period, and it is my belief that it can only be explained by a transformation that the Mesolithic population were themselves instrumen-tally engaged in. While this may not have involved the movement of entire population groups as distinct entities from the continent to Britain, it is extremely likely that the exchange of personnel between groups took place both during and prior to the transition. For, while the manufacture of new stone tool types 54 Gene-flows and social processes> the potential of genetics and archaeology and conceivably aspects of animal husbandry might have been learned by indigenous people, the techniques of potting and cereal cultivation are more likely to have been transmitted by inter-marriage or prolonged visiting and apprenticeship. While it has conventionally been maintained that Britain and Ireland had no contact with the European continent during the later Mesolithic (e.g. Jacobi 1976), this argument has been made on the basis of the morphological distinctiveness of microlithic assemblages. Yet the degree of similarity of artefacts cannot be taken as an index of the degree of interaction between social groups, while there is now evidence of the presence of domesticated cattle in Mesolithic Ireland (Woodman and McCarthy 2003), demonstrating that indigenous hunter-gatherers did have some dealings with continental Neolithic groups (see Thomas 2004b for more detailed discussion). This means that the transfer of domesticates and Neolithic material culture into Britain is likely to have taken place in the context of long-established relationships with continental communities. In this connection, it is important to remember that most of the Neolithic groups that existed along the Atlantic coasts facing the British Isles by 4000 BC (in Brittany, Normandy, the Low Countries, Northern Germany, Denmark and southern Sweden) were most likely indigenous peoples who has adopted a new way of life through acculturation or appropriation (Arias 1999.432). Their connections with British hunter-gatherer societies are therefore likely to have been long-established. Frontiers, interaction and hybridity These arguments suggest that our investigation of the genetics of prehistoric communities in Europe needs to take more account of what happens when personnel are exchanged between spatially juxtaposed communities which are not bounded but permeable. After all, recent strontium isotope analysis by Bentley et. al. (2003) on skeletons from Vaihingen and other LBK sites in Germany suggests that between 30 and 50% of the burials there were of non-local origin, putatively Mesolithic people who had married in to the community. This was happening not in the context of expansion, but of a period of prolonged stasis in which some form of interaction took place between Mesolithic and Neolithic communities. It is these extended periods during which the Neolithic did not expand that I want to emphasise. Recently, Dusan Boric (2005) has offered a cogent critique of the post-colonial assumptions implicit in the notion of a 'frontier' between Mesolithic and Neolithic groups in Europe. He argues that such a model reinforces a dichotomous relationship between two essentialised and ahistoric ideal types, hunters and farmers, and that it implies a social evolutionary scheme in which the replacement of foraging by farming is an inevitable outcome. As an alternative, Boric presents an account of Lepenski Vir in which multiple, complex identities existed side by side (2005.99). Undoubtedly, Boric is correct to reject the view that the Mesolithic and the Neolithic re- Fig. 2. Villeneuve-Sain-Germain longhouses in northern France (from Scarre 2002/ 55 Julian Thomas presented two fixed and opposed entities. However, it may still be worth retaining the terminology where we acknowledge that sixth-fourth millennium BC Europe was a patchwork of different kinds of Mesolithic and Neolithic societies, each of whose social and economic arrangements were continually open to transformation. Wherever formally 'Mesolithic' (that is, indigenous hunter-fisher-gatherer) and 'Neolithic' (having access to domesticates, ceramics and polished stone tools) communities came into spatial juxtaposition, the potential was created for social interaction and cultural innovation. The 'frontier' between such groups is best seen as a zone in which unpredictable social and cultural exchanges might take place: possibly violent (Gronenborn 1998), but also potentially creative and transformational. It is unhelpful to think of such interactions as taking place under the sway of a 'law of cultural dominance' (Sahlins and Service 1960.69), in which the 'inferior' Mesolithic was always influenced or dominated by the 'superior' Neolithic. Rather, the encounter might affect either group equally, through a process of hybridization or creolization of cultural repertoires that were never 'pure' to begin with. Thus, while hunter-gatherer groups in central and northern Europe adopted ceramics and other Neolithic innovations, it is arguable that in the post-Bandkeramik era, the various forms of Neolithic that emerged incorporated elements of a Mesolithic cultural inheritance (Arias 1999.445). Simply because societies that used ceramics, polished stone tools and domesticates eventually replaced ace-ramic hunting and gathering groups across much of Europe, we should not accept the teleological argument that this was the only possible outcome. I suggest that through these episodes of interaction at relatively long-lived 'frontiers', indigenous groups acquired and assimilated new cultural and material resources, but in addition the Neolithic was itself repeatedly transformed. There are a series of reasons why such situations of contact and interaction might persist over lengthy periods: where pioneer farmers operated under conditions in which land and re- Fig. 3. Poland at the time of the formation of the TRB, showing 'enclaves' of SBK/Lengyel Neolithic settlement in relation to Late Mesolithic sites (from Zvelebil 2004). sources were plentiful, and had no need to expand further; where populations of hunter-gatherers were dense, and operated elaborate subsistence regimes; where physical circumstances restricted the expansion of farming economies; and where economically diversified Mesolithic groups would have perceived no benefit in adopting new resources and technology or being incorporated into different cultural or symbolic regimes. There are at least three distinct areas in which we can identify such phases of standstill and interaction. The first would be following the following the establishment of the Neolithic in the northern Balkans, where Esther Banffy (2004.57) points to prolonged contact between Starčevo farmers, Koros communities who may have been of indigenous origin but who combined the use of wild and domesticated resources, and Mesolithic hunters in Transdanubia during the earlier sixth millennium BC (see also Whittle 2005). Out of this interaction emerged the earliest Bandkeramik, which combined elements of the Starčevo ceramic tradition with timber long-houses. The longhouse implies the formation of an entirely new mode of sociality: not the imposition onto central Europe of a Balkan model, but something that developed in the protracted negotiation 56 Gene-flows and social processes> the potential of genetics and archaeology between hunters and farmers, and which facilitated the subsequent pioneer expansion into the loess country of Europe north of the Alps and Carpathians (Gronenborn 1999). Similarly, in the period following the Bandkeramik expansion we can identify parallel processes in western France and the North European plain which began with the exchange of ceramics, stone tools, livestock, furs, and presumably also personnel between Neolithic and Mesoli-thic communities, and culminated in the formation of hybrid forms of sociality which drew on both traditions, with Cerny and the earliest TRB (Doman-ska 2003; Nowak 2001; Zvelebil 2004.51). Just as the formation of the LBK introduced an entirely new social focus and forum in the shape of the longhouse, so with Cerny and TRB it was monumental funerary architecture that was central to a new kind of social life (Midgley 2005.36). Again, I would stress that this was a transformation of the Neolithic, arising out of interaction, and introducing elements which had simply not been there before. It was the development of a new form of Neolithic, in which kin relations were expressed through mortuary monuments as much as in the domestic context, that facilitated the final phase of the Neolithic expansion in Europe: into Scandinavia and the British Isles. Here the process was more thoroughly one of acculturation than elsewhere (Price 2000. 299). It is important to note that the significance of domesticated species altered subtly at this point. Where agriculture spreads by population movement, we might expect domesticated plants and animals to form an integrated food-production system, and to represent staples. However, where we have populations of hunter-gatherers who have a stable economic base of their own, the initial occurrence of domesticates beyond the 'agricultural frontier' is likely to be as exotica and novelties. Interestingly, there is a growing pattern of the identification of domesticated cattle in pre-Neolithic contexts in southern Scandinavia, southern Brittany, the Rhine Basin, the Alpine foreland, northern Poland and Ireland (Zvelebil 2004.49; Woodman and McCarthy 2003). In the Mesolithic context, the acquisition of a single domesticated cow and its slaughter for communal consumption might have had an appreciable impact on local social relationships, in terms of status, prestige and personal obligation. It is arguable that the penetration of north-west European Mesolithic societies by Neolithic systems of consumption and prestige was one of the mechanisms that led to their transformation. But as we have stressed above, it should not be presumed that this was a one-way process, for the acquisition of goods and raw materials, and the incorporation of personnel from Mesolithic communities would have held a transformative potential for Neolithic societies. Clearly, the societies that inhabited northern and western Europe between the sixth and fourth millennia BC were diverse in terms of their various combinations of hunting, gathering, fishing, herding and horticulture, their material culture, and their social organisation. The contacts and relationships between these groups will have been more complex still. The articulation of social reproduction and social interaction will, under these circumstances, have resulted in elaborate sequences of non-reversible historical change. I have dwelt on all of this complexity because each of these processes will have had their own demographic consequences and correlates. The patterns that we observe in the DNA evidence are the outcome of these processes, overlaid with four millennia of further developments. There remains a massive contribution that human genetics can make to the study of this period, but it may be that it is now time for it to address a finer-grained picture of the Neolithic transition. 57 Julian Thomas REFERENCES AMMERMAN A.

Archaeogenetic studies, which examine contemporary geographical variations in the frequencies of various genetic markers have not succeeded in addressing the complex Neolithisation process at the required level of spatial and temporal resolution. Moreover, these studies are based on modern populations, and their interpretive genetic maps are often affected by post-Neolithic dispersals, migrations, and population movements in Eurasia. Craniometric studies may provide a solid link between the archaeological analysis ofpast events and their complex relationship to changes and fluctuations in corresponding morphological and thus biological variations. This paper focuses on the study of craniometric variations between and within Pre-Pottery Neolithic, Pottery Neolithic, and Early Neolithic specimens from the Near East, Anatolia and Europe. It addresses the meaning of the observed multivariate morphometric variations in the context of the spread of farming in Europe. IZVLEČEK - Vedno več je dokazov, da širjenje poljedelstva v Evropi ni bil enkraten, enoten proces, temveč je obsegal kompleksen niz procesov, kot so demska difuzija, migracije ljudstev, mobilnost meja in kolonizacija na način žabjega skoka. Arheogenetske študije, ki preučujejo sodobne geografske variacije in pogostost različnih genskih označevalcev, niso uspele pojasniti kompleksnost prostorske in časovne strukturiranosti procesa neolitizacije. Ker te študije temeljijo na modernih populacijah, na njihove interpretativne genetske zemljevide pogosto vplivajo post-neolitske razpršitve, migracije in premiki prebivalstva v Evraziji. Kraniometrične študije lahko preskrbijo trden člen med arheološkimi analizami preteklih dogodkov in njihovimi kompleksnimi razmerji s spremembami in nestalnostmi v ustreznih morfoloških in bioloških variacijah. Ta članek se osredotoča na preučevanje kraniometričnih variacij med in znotrajpredkeramičnih in keramičnih neolitskih ter zgodnje neolitskih populacij na Bližnjem vzhodu, v Anatoliji in v Evropi.

KEY WORDS - neolithisation of Europe; Early Neolithic; craniometric analysis; multivariate statistical methods; sex-specific variability Introduction The Neolithic period in the Near East and Anatolia was a period of experimentation, innovation and change. It was particularly demarcated by the 'cultural explosion' during the pre-pottery Neolithic B period (Aurenche and Kozlowski 1999) in the Levant, Mesopotamia, Iran and Anatolia. Preliminary analy- ses of the space-time dynamics of these cultures indicate that observed changes in the Levant's settlement patterns, population density and size, and cultural aspects such as architectural style, lithic typological attributes, etc. are possibly associated with a diffusive process to island and mainland Greece dur- 61 Ron Pinhasi ing this period (Perles 2001). It is not clear, however, whether this process was for the most part cultural, demic, or a combination of both, and nor if it combined with a process of overland dispersal from western Anatolia to southeast Europe (Ozdo-gan 1997). It is clear that the Neolithisation process in Europe varied by region/culture and that it comprised a series of complex processes involving population fusion, fission, leapfrog colonisation, dispersals and migrations. Analyses of radiocarbon dates (Pinhasi et al. 2005), and craniometric data (Pinhasi & Plu-ciennik 2004; Pinhasi 2003), highlight the complexity of the Neolithic transition in the various regions, and stress the need to examine its spatiotemporal, archaeological and biological aspects in greater scope and resolution. Some analyses of the craniometric data set, utilising skeletons from Pre-Pottery and Early Neolithic occupational phases from Near Eastern, Anatolian and European sites, have demonstrated a high degree of morphological heterogeneity between and within populations. In particular, a high degree of morpho-metric heterogeneity has been detected and reported for the Near Eastern/Anatolian Pre-Pottery Neolithic specimens (Pinhasi 2003). This heterogeneity contrasts with the morphological homogeneity among the Central Anatolian Catalhoyuk skeletal population and that of mainland Greece, the Balkans and southern Hungary. But what does this observed craniometric pattern tell us about the nature of the Neolithisation process in the various regions of the Near East, Anatolia, and Europe? Ammerman & Cavalli-Sforza (1971) suggested that the 'Wave of Advance' (WOA) of the Neolithic farmers progressed at an averege speed of 1 km/yr, but that it was twice as rapid along the coasts of the Mediterranean (Cardial Neolithic and associated cultures). At present, however, the mosaic chronomet-ric pattern of the Neolithisation of Italy (Skeates 2003; Forenbaher and Miracle 2005) does not support a straightforward linear demic diffusion, but points to the involvement of other processes, specifically the maritime colonisation of certain parts of the peninsula. A recent analysis of the wave of advance, using radiocarbon dates from 735 early Neolithic sites in Europe, the Near East, and Anatolian sites (Pinhasi et al. 2005), has demonstrated high correlation coefficients (R > 0.8) for some of the Mesopotamian, southeast Anatolian and Levantine Probable Centres of Diffusion (POAs) and thus supports both in magnitude and average speed (km/year) the original approximation of Ammerman & Cavalli-Sforza (1971). In fact, the obtained average rate of the Neolithic spread over Europe was 0.3-0.6 km/yr, which is consistent with the prediction of the demic diffusion model. Pinhasi et al. (2005) examined whether the chronometric correlations between early Neolithic occupation in Europe and the Near East/Anatolian zone allow the interpolation of a best-fit geographic region in the Near Eastern/Anatolian from which a WOA probably originated. They reported that the most likely region was the northern Levant/Mesopotamia. This observation is in disagreement with results obtained from the craniomentric study, which suggests a centre of dispersal in Central Anatolia (Pinhasi & Pluciennik 2004). At this stage, it is not clear whether or not the slow rate of overall spread and its essentially linear character, as shown by the above-mentioned analysis, is a true reflection of a single historical process which was for the most part demic in nature, or perhaps is merely an artefact - possibly the outcome of a series of movements and transitions that, when combined (i.e. when examining pan-continental trends), appear to be linear. Another possibility is that the chronological cline reported by Ammerman & Cavalli Sforza (1971) is the outcome of cultural diffusion, and thus that the Neolithisation process involved for the most part an economic/cultural transformation of in situ Mesolithic populations. It is therefore evident that we are now entering a new phase in the study of the Neolithic transition, one that requires greater attention to details and a finer focus on the application of specific archaeological and morphometric methods to tackle the process of Neolithisation on a regionallevel. It appears that a Neolithic dispersal from the Near East/Anatolia to Europe may have occurred at least twice: once as a PPN maritime expansion from the Levant/southern Anatolia, and later on during the Pottery Neolithic period as an overland dispersal from Central/Western Anatolia to southeast Europe (Perlés 2001; Ozdogan 1997). This means that more than one founder Neolithic population dispersed out of the Near East/Anatolia to Europe, and that each dispersal event must have left certain demographic and genetic signatures on modern Europeans. At the same time, the rise of regional variations in cultural 62 Neolithic skull shapes and demic diffusion> a bioarchaeological investigation into the nature of the Neolithic transition aspects, as one can deduce from the certain differences in artefact styles, and the like, may have been the outcome of a period of fragmentation and isolation of certain communities, possibly associated with the severing of existing trade and exchange networks. Processes of fission, fusion, consolidation and isolation should therefore leave biological traces that to a certain extent correspond to those that can be read from the material record. A demic diffusion process involves gene flow, which in general reduces the genetic and morphological difference between populations. In contrast, cultural diffusion will not have a direct effect on the morphological attributes of these populations, so that new artefacts, domesticates, and architectural features may appear in a given period in a certain region without any apparent change in the morphology of the skeletons from this period. Genetic studies have not provided the required resolution to address this question (Pluciennik 1996). In particular, the time resolution applied in most genetic studies is too vast to recognise archaeological/ historical processes of the scale involved in Neolithic studies (Brown & Pluciennik 2001). Craniometric studies may provide the 'missing link' between genetic studies, which for the most part examine geographically-based variations in a given marker among modern populations, and the Neolithic archaeological record. But can craniometric studies 'translate' observed biological affinities and variability among skeletal populations from various archaeological sites to corresponding historically-based population variations between archaeological cultures? The answer to this question requires examination of the relationship between 'archaeological cultures' and past human populations, whereas the latter is assumed to correspond to past ethnicity. Thus, the question may be rephrased, and one should ask whether the appearance of specific 'archaeological cultures' defined according to certain non-functional characteristic elements of their archaeological toolkit (such as pottery style) is directly associated with a corresponding biological process such as population differentiation, admixture, isolation and the like. This paper will attempt to take an initial step towards furthering our current understanding of this complex polemic by systematically examining mor-phometric relationships and variations between Near Eastern, Anatolian and European Neolithic populations from specific sites that were allocated to a specific group on the basis of their archaeological attributes (e.g. Cardial, Starcevo-Koros-^ris, etc.). Morphometric variations and similarities between the groups should therefore shed some light on the relationship between archaeological entities and the corresponding biological attributes of past populations. Materials and Methods The skeletal sample is described in Table 1. It consists of Pre-Pottery Neolithic specimens from the sites of Zawi Chemi, Hotu, Abu Hureyra, and ^ayo-nu in the Near East and Anatolia; Pottery Neolithic specimens from ^atalhoyuk-Turkey; Early Neolithic specimens from Nea Nikomedeia-Greece, Vlasac and Lepenski Vir-Danube Gorge; various specimens from the Cardial Neolithic, Starcevo-Koros-^ris (SKC) complex; and the Linienbandkermik (LBK) sites of Visen-hauser Hof, Sonderhausen and Schwetzingen. The sample is first analysed by groups (Tab. 1) which are defined according to either specific archaeological cultural entities (e.g. "Cardial") or site/culture (e.g. "Sondehausen-LBK"). The following set of standard craniometric variables that best define the gross moprphological shape and dimensions of the craniofacial complex are utilised: • Vault height: BBH; • Vault length: GOL; • Vault breadth: minimal- MFB and maximal- XPB; • Facial dimensions: Nasal height- NLH and breadth- NLB; • Orbital height- OBH; • Upper face height-NPH; • Bizygomatic breadth- ZYB. Three statistical methods are then applied to the samples: 1. Squared Mahalanobis Distances The generalised distance, D2 is a statistic that is often applied in the estimation of group differences between biological populations. It has been extensively applied in craniometric studies of prehistoric populations (see, for example, Howells 1973; Keita 1990; 1992). 2. Discriminant Function Analysis The method is used in order to discriminate between groups, and to derive posterior probabilities for the correct classification of cases to one of the existing groups (thus indicating the degree to which it is possible to correctly assign a give case to a given group on the basis of the derived discriminant functions). 63 Ron Pinhasi Another important use of discriminant function analysis is the actual positioning of populations and the interpretation of functions (Howells 1973). The b coefficients of each function can be interpreted in a similar manner to factor loadings - that is, the larger the coefficient, the greater the contribution of the respective variable to the discrimination between groups. However, these coefficients do not tell us between which of the groups the respective functions discriminate. This can be quite effectively achieved, however, by plotting group centroids and individual discriminant function scores (per case for the first two discriminant functions). 3. Principal Components Analysis Principal Components Analysis (PCA) is a data reduction technique. It reduces dimensionality by calculating a series of uncor-related factors, or PCs, whose total number should be significantly less than the total number of variables. PCA is for the most part an exploratory method, which is therefore to a certain extent subjective. However, its strength lies in the fact that it can be applied directly to the data set without the need to assign each case to a given group. The first PC explains the largest amount of the total variation, and in most biological studies it mostly covers size-related variation. The second PC explains even less of the variation, and so on in descending percentages. It is therefore usually sufficient to examine only the first few PCs (depending on the percentage of variation that each one explains). Each case has a set of factor scores corresponding to each PC. By plotting bivariate graphs of the factor's scores (usually for the first vs. second component) it is then possible to assess any detectable relationship between the cases (in this specific case, Neolithic specimens). Furthermore, each PC contains a set of factor loadings for each variable, and it is therefore pos- Location Latitude Longitude N M F Period Group code Abri De Pendimoun 43.48 7.30 1 Cardial 6 Arene Candide 38.33 16.12 1 Cardial 6 Arma Dell'aguila 42.37 1337 2 1 1 Cardial 6 Castellar 43 48 7.30 1 1 Cardial 6 Chateau neuf 43.24 512 1 1 Cardial 6 Condeixa 40.06 8.30 26 11 15 Cardial 6 Finale Ligure 44.12 8.18 2 1 1 Cardial 6 Grotte Sicard 43.24 512 1 1 Cardial 6 Sabassona 41.38 2.18 1 1 Cardial 6 Salces 42.54 254 2 1 1 Cardial 6 Çatalhöyük 37.10 32.13 16 7 9 Pottery Neolithic 2 Lepenski Vir 44.33 22.03 5 4 1 Danube Gorge 5 Vin;a 44.48 20.36 3 2 1 Danube Gorge 5 Schwetzingen 49.38 8.58 10 7 3 LBK 7 Sonderhausen 51.12 10.54 12 5 7 LBK 8 Viesenhäuser Hof 48.50 9.-13 17 9 8 LBK 9 Nea Nikomedeia 40.65 22.30 10 3 7 Greek Neolithic 3 Abu Hureyra 35.87 3840 2 2 PPN 1 Çayönü 38.23 39 65 3 2 1 PPN 1 Hotu 35.81 53.90 PPN 1 Zawi Chemi 37.08 43 87 1 1 PPN 1 Deszk 46.22 20.25 2 1 1 SKC 4 Devetaïkata Peïtera 43.23 24.95 1 1 SKC 4 Endröd 46.94 20.78 1 1 SKC 4 Gura Bacului 46.48 23.36 1 1 SKC 4 Kasanlak 42.36 25 24 1 1 SKC 4 Vészto-Mágori 46.94 20.23 6 6 SKC 4 Tab. 1.

It is then possible to interpret the relationship between the reduced set of variables and the obtained PCs, or in other words, to see if there is a meaningful biometric relationship between the variable set and the obtained PCs. Results The following is a description of the results obtained by analysing the same set utilising each of the above methods. a. Squared Mahalanobis Distances Results of the analysis are provided in Table 2. The largest Square Mahalanobis Distances (D2) between a single site/culture, and the remainder are detected 64 Neolithic skull shapes and demic diffusion> a bioarchaeological investigation into the nature of the Neolithic transition in the case of the Pre-Pottery Neolithic set and the rest with the exception of the Starcevo-Koros-^ris (SKC) and the Cardial Neolithic complexes. The second cultural complex with large D2 distances is the Danube Gorge Neolithic (comprising specimens from the sites of Lepenski Vir and Vlasac). The group has large D2 distances from all other sites/complexes. The third site with large D2 distances from the remainder is the south-western LBK site of Viesenhau-ser Hof. Surprisingly, the specimens from this site have large D2 distances not only from most other Neolithic complexes, but also from the two other LBK sites of Schwetzingen and Sonderhausen. Small D2 distances (< 4.0) are observed in the case of three sites/complexes: Catalhoyuk, Nea Nikome-deia and SKC. The D2 distances between the three complexes are all below 3. Furthermore, Catalhoyuk shows small distances from all other complexes except PPN, Danube Gorge and Viesenhauser Hof. Exactly the same trend is noticed in the case of Nea Nikomedeia. The SKC complex differs from the other two only by having a slightly lower D2 value for its distance from Viesenhauser Hof (3.98). In sum, the following trend is apparent from the Square Maha-lanobis Distances analysis of the sites/complexes: the largest distances between a given complex/site and the remainder is indicated in the case of the PPN complex, the Danube Gorge complex and the site of Viesenhauser Hof. Small D2 distances are observed between Catalhoyuk, Nea Nikomedeia and SKC, Cardial Neolithic and two out of the three LBK sites. The small distances point to minimal morpho-metric differences between the crania from each of these sites/complexes. It therefore suggests minimal morphological differentiation between these groups. The sharp contrast in D2 distance trends between the LBK site of Viesenhauser Hof and the LBK sites of Schwetzingen and Sonderhausen is intriguing. b. Discriminant Function Analysis i.) Discrimination In general poor discrimination is achieved between the various groups (Tabs. 3a-b). The lack of discrimination between most groups does not indicate a flaw in the data, but points to the fact that there are minimal inter-group morphometric differences and maximal intra-group differences. In other words, the selected groups are not biometrically (and hence biologically) distinct enough on the basis of the utilised craniometric set to facilitate group-based discrimination. This leads us to the next question, which is why there is no sufficient difference between these groups. And what does the lack of difference indicate? It is now necessary to focus on the range of variability in each group by looking at the contours that delimit some of the groups in relation to the centroids for each group (numbered black squares, Fig. 1). It is evident that the second discriminant function (the Y axis in Fig. 1) in fact manages to differentiate between the PPN group and the others. It therefore indicates that differences in the morpho-metric dimensions of the PPN specimens and the rest of the groups allow one to discriminate between them. It also suggests that if we apply this function to new specimens, it will allow us to successfully discriminate and classify PPN and "non-PPN" specimens on the basis of their craniometric dimensions. It therefore follows that the PPN specimens as a group share a distinct set of craniometric dimensions, reflecting a distinct skull vault/face shape. The position of Catalhoyuk within the Nea Nikomedeia group boundaries further point to the lack of biome-tric differentiation between them. A great degree of variability is evident in the case of the Cardial Neolithic complex, and the LBK groups. The latter show a pronounced degree of differentiation.

Squared Mahalanobis distances between the samples. Distances greater than 4 D2 units are in bold. 65 Ron Pinhasi centroid. As only three specimens from this group were included (due to missing data), it is not possible to draw any conclusions based on the sample. The large degree of morphome-tric variability within the Cardial Neolithic group suggests that it may in fact include several biological populations. Thus, both the PPN and the Cardial groups comprise specimens from various sites that span a large geographical range (see Tab. 1). a.

Discriminant Function Analysis ii) Classification Table 4 provides the results of the classification of the various specimens for each group. Only 44.6% of the cases were correctly classified. The highest percentage of correct classification was in the case of Sonderhausen (75%), Viesenhauser Hof (66.67%), and PPN (60%). Poor classification was noted for the SKC, Danube Gorge, Cardial Neolithic and LBK-Vie-senhauser Hof. C. Principal Components Analysis i.) Total sample (pooled sexes) The principle components analysis examined the specimens from the above-mentioned groups using the same craniometric variable set. However, the method does not require the assignment of specimens to groups, thus allowing a 'natural' pattern of group differentiation to appear. The analysis shows no clear differentiation between the groups (Tabs. 5a-c). Figure 2 is a scatterplot of the factors scores Fig. 1. Discriminant function analysis of craniometric measurements of skulls from 9 Early Neolithic cultures/sites. values of the various skulls on the first and second principal components. The SKC, Cardial and LBK complexes display the most extensive range of variability. It therefore appears that it is not possible to detect clear morphometric differences between groups on the basis of this method when using the craniometric set provided. Also, note that most of the variability is accounted for by PC1 (55.67%), while only 12.29% of the variability is accounted for by PC2. It therefore seems that as PC1 is unipolar (factors loadings of all variables are positive), it mainly accounts for size-related variability. The positive factor loadings of the second component are for facial height measurements - more specifically, upper facial height, nasal height, and orbital height load positively on PC2, while the other variables have negative loadings. It therefore appears that the Danube Gorge Neolithic specimens have particularly low faces, while some of the SKC, LBK and Cardial specimens have long faces. ii.) Sex-specific patterns A fair degree of overlap is expected when running a PCA on pooled rather than sexed samples (i.e. when male and females of each group are combined). A sex-specific analysis may allow one to differentiate between some of these groups. Figure 3 is a scatterplot of the same PCs, but indicating the values of each case (i.e. skull) by sex. Good separation is indicated between male and females: female specimens for PC1 < -0.8 values and male specimens for PC1 > 1. However, males and females overlap for -0.8 < PC1 < 1. About 2/3 of the males and 2/3 of the females fall on the overlapping range. It therefore means that a sexed analysis of the same set will only partially reduce the overlap between the groups, as only a third or so of 66 Neolithic skull shapes and demic diffusion> a bioarchaeological investigation into the nature of the Neolithic transition 01 < oj -1 CN a CL the overlap is directly related to sexual dimorphism. Discussion The Squared Mahalanobis Distance analysis clearly indicates that D2 distances between ^atalhoyuk, Nea Nikomedeia, SKC, Cardial Neolithic, and two out of the three LBK sites are small. These distances indicate minimal inter-group morphometric differences in crania from each of these sites/complexes. The sites/cultures with the largest distances from the rest are PPN, Danube Gorge, and the LBK site of Viesenhauser Hof. The large D2 distance between the LBK sites of Viesenhauser Hof and the LBK sites of Schwetzingen and Sonderhausen shows extensive craniometric variation between these LBK populations. The LBK culture dispersed across Central Europe in less than 500 years (Bogucki 2003). Considering the rapid speed of this dispersal and the extensive gene flow between LBK communities (as there were no major geographic barriers to prevent it), it is necessary to rule out the possibility that the observed morphological differences between the LBK populations analysed were the outcome of selection and/ or stochastic changes to the genetic structure of these populations due to drift. It therefore appears that the only plausible explanation is that one or more of these populations either mixed with local Mesoli-thic hunters, or even that some of these populations were indigenous hunters that adopted farming. However, these hypotheses can only be tested with the analysis of Mesolithic populations, which is beyond the scope of this article (see Pinhasi 2003).The Discriminant Function analysis did not discriminate well between the groups. However, discrimination was achieved between PPN on the one hand and Nea Nikomedeia and ^atalhoyuk on the other. Moreover, the function discriminated between Sondehausen, Viesenhauser Hof and Schwetizngen. The Principal Components Analysis (PCA) did not provide any additional information about the relationship between the specimens in relation to their archaeological cultures. However, it has been shown that differentiation between populations is hindered to a fair extent by the pooling of male and female samples. It is possible that sex-specific PCA will result in better differentiation between the groups. Furthermore, it is evident that specimens from some of the archaeological cultures, such as LBK and Cardial Neolithic, vary greatly in their morphologies, while others, such as the Danube Gorge Neolithic, are more / / \ 1 / /•' \ \ • //• *« * / • •••• • / A • » // \m rA— V Z/ \ Culture/Site SKC PPN • Nea Nikomedeia • LBK • Danube Gorge Neol • Qatalhoyuk • Cardial PC1 (55.67%) Fig. 2.

Ozdogan (1997) points out that the Neolithic communities of the Central Anatolian plateau form a distinct entity which differs from the south-eastern Anatolian, Levantine and Mesopotamian contemporaneous cultures in settlement pattern, architecture, lithic technology, bone tools, and other archaeological aspects. There is no simple corollary between specific cultural-archaeological entities and biological populations. However, in the case of the above analyses, the population of ^atahoyuk differed biologically from the populations of the Near East and southeast Anatolia and were similar to the SKC and Nea Neikomediea cultures. Indeed in a previous publication (Pinhasi 2003), it was demonstrated that the Squared Mahalanobis Distance between ^atalho-yuk and ^ayonu is twice to three times the average distance between the former and any of the Early Neolithic southeast or central European Early Neolithic populations. The above analysis therefore confirms the archaeological observations made by Ozdo-gan (1997) and reaffirms in this specific case a correspondence between cultural boundaries that define a prehistoric culture and its biological basis. A similar factor may explain the position of the Danube Gorge specimens. Pinhasi and Pluciennik (2004) pointed out that the craniometric analysis of the Danube Gorge Mesolithic and Neolithic specimens indicate a possible continuity in cranial morphology in this micro-region that contrasted with the Mesoli-thic-Neolithic morphometric discontinuity in the case of other regions in southeast Europe. This observa- 67 Ron Pinhasi tion is also in accord with that made by Tringham (2000), who asserts that it is "...unjustifiable to assume that the complexities of hunter-gathering society and the scenarios of their contact with agriculturalists that have been developed in the Danube Gorges sites also apply to southeast Europe outside the Danube Gorges".

According to Perles (2001; 2003) the first pioneer colonisers of Greece were Near Eastern PPNB farmers who brought with them the 'Neolithic package', minus pottery. She then asserts that Nea Nikomedeia and other mainland Early Neolithic Greek sites are not associated with a westward 'wave of advance' of Anatolian populations Tab. 4. Results of the classification of cases to each of the nine groups* (in percentages) on the basis of the discriminant functions. However, the craniometric analysis indicates no morphological differences between Nea Nikomedeia and the ^atalhoyuk populations, which contrasts with the differences between these and the PPN Levantine/ Anatolian samples. There are no grounds for believing that the settlement of mainland Greece, either by land or sea, can be compared with the slow movements of populations characteristic of the Cardial or Danubian 'waves of advance'. On the contrary, it seems to relate to these long-distance expeditions, well exemplified in the Mediterranean by the colonisation of Crete, Corsica and the Balearic Iislands, for instance" (Perlès 2001). ? 9 + 6 ♦ .6 • ♦ • • ♦ ♦ < A A • ♦ » ? ♦ * » ♦ ♦ * f *♦ ♦ ♦ • • ♦ * ♦ * • • -?-•— ♦ » • ♦ « ♦ -»- PC1 (55.67%) SEX • Mite ♦ Female Fig. 3. Sexual dimorphism in craniometric measurements. The left and right sections comprise females and males only, respectively, while the middle section shows the range of PC1 scores in which the two sexes overlap. The morphometric relationship between the LBK populations and those of southeast Europe and Anatolia appear to be complex. The separation between the sites of Viesenhauser Hof, Sonderhausen and Schwetzingen (Fig. 1) points to pronounced morpho-metric differences between these populations. This finding is in accord with Jochim's assertion (2000) that new archaeological evidence indicates greater regional differentiation within the LBK area than was previously assumed. It also supports the observation made by Bentley et al. (2002) using strontium isotope analysis which indicated that about 25% of the Schwetzingen individuals were non-local migrants, thus pointing to extensive mobility and mate exchange among LBK populations, possibly also involving local Late Mesolithic hunters. The position of the Cardial Neolithic in the above-mentioned analyses is unclear. Perhaps the large range of variability observed in the sample utilised reflects the fact that we are dealing with several biological populations spread across a vast geographical region. Only more analyses with a finer geographical and archaeological resolution will allow one to examine the biological nature of this cultural entity.

By applying three specific methods to the same set of specimens, it investigated not only the affinities and differences between these specimens, but also the type of answers that one may obtain from the interpretation of biometric data. Furthermore, some specimens were categorised according to archaeological units of vast spatiotemporal scope, such as 'Cardial Neolithic', while others had a much narrower spatio-temporal scope (such as LBK- Viesenhauser Hof). This categorisation scheme was applied in order to see whether groups that share a given archaeological culture and are from a relatively narrow spatio-temporal range (LBK sites) are biologically more similar to each other than to other groups from different archaeological contexts. The results show that this was not the case, and therefore reaffirmed the previous observations (Pinhasi 2003; Pinhasi and Plucien-nik 2004) that while biological differences between specimens relate to the specific archaeological culture-specific context, the relationship is complex. Nevertheless, the similarities between SKC, Nea Niko-medeia and Catahoyuk, and the differentiation between the PPN and other Early Neolithic groups show that craniometric studies can shed more light on the nature of the Neolithisation process in various regions, and provide an essential link between genetic studies and archaeology.

The first was posed originally by Robert Braidwood more than fifty years ago, and concerns why farming was adopted in southwest Asia early in the Neolithic, and not earlier. The second concerns the usually opposed processua-list and post-processualist approaches to the Neolithic. The paper seeks to model the processes at work through the Epi-palaeolithic and early Neolithic, showing how the trend towards sedentism and storage offood resources coincided with the emergence offully symbolic cognitive and cultural faculties. The former fed more mouths, and led to the adoption of farming practices that further intensified food productivity. The latter made possible and desirable the symbolic construction of large, permanently co-resident communities. The spread of farming may then be understood as the expansion of a complex way of life that involved communities living together in larger groups, with denser, richer cultural environments, controlling not only the built environment of their own settlements, but also the productivity of the agricultural environments that surrounded them. IZVLEČEK - Razpravljamo o dveh vprašanjih, za kateri se je izkazalo, da sta povezani. Prvo je zastavil Robert Braidwood pred več kot petdesetimi leti in se ukvarja s tem, zakaj je bilo poljedelstvo sprejeto v jugozahodni Aziji v zgodnjem neolitiku in ne prej. Drugo pa se nanaša na nasprotujoče se pro-cesualne in post-procesualne pristope v neolitiku. V članku skušam modelirati proces, ki je deloval v času epi-paleolitika in zgodnjega neolitika. Pokažem, kako je trend v smeri sedentizma in shranjevanja hrane sovpadal s pojavom čisto simbolnih, kognitivnih in kulturnih zmožnosti. Prvo je nasitilo več ust in je pripeljalo do sprejema kmetijskih praks, ki so pospešile proizvodnjo hrane. Drugo pa je oblikovalo takrat mogočo in željeno simbolno strukturo velikih, sobivajočih in stalno naseljenih skupnosti. Širitev kmetovanja lahko tako razumemo kot ekspanzijo kompleksnega načina življenja, ki je vključevalo življenje velikih skupnosti druge ob drugi, bogato kulturno okolje in nadzor vasi in polj ter pašnikov, ki so jih obkrožali. KEY WORDS - Epi-palaeolithic; Neolithic; cognitive archaeology; cultural evolution; origins of farming Introduction There are two problems in the Neolithic of southwest Asia that have proved resistant, and neither have been the central concern of those working on the Neolithic. One of them has persisted since the middle of the twentieth century, while the other appeared more recently. I shall attempt solutions to those problems. The process of Neolithisation as I will model it in a sketchy outline leads to the conclusion that the early Neolithic societies had evolved minds and symbolic cultures that were for the first time in human history recognisably like those that we enjoy. In that sense, the Neolithisation process in southwest Asia was the path to modernity. At the end of the period with which this essay is concerned, around 7000-6500 BC, there are archaeological indications of increases in the form, extent and density of settlement around the southwest Asian core area. These indications may suggest that there was demographic growth (together with other factors) within the region that required expansion of the set- 71 Trevor Watkins tied area. However, the rest of southwest Asia was by no means an empty quarter. I suggest that expansion from the core area produced a ripple effect as societies in other parts of the region began to feel demographic pressure expanding from the core area, and were themselves also adopting the new, dynamic symbolic cultural package that included mixed farming, and beginning to experience population growth. The pressures within southwest Asia thus expanded in whichever directions were possible, and may have provided the initial pulse of Neolithic cultural forms and farming economies into southeast Europe. The persistent question that has hovered over us since the middle of the twentieth century was that posed by Robert Braidwood when he sought to unravel and understand what we would now call the process of Neolithisation on the basis of his multi-disciplinary research programme in northeast Iraq (Braidwood 1960 is a simple, direct and accessible statement of his views). Following the conclusions of the early work by his environmentalist collaborators, Braidwood dismissed climate and environmental change at the end of the Pleistocene period (Gordon Childe's hypothesised driver) as the pressure that prompted early Neolithic societies to adopt crop cultivation and animal herding. His collaborators found no evidence of significant climatic or environmental change in the final Pleistocene and earliest Holocene. In any case, Braidwood reasoned, similar sequences of cold phases followed by warming had occurred frequently during the Pleistocene without prompting human societies in southwest Asia to adopt farming. If the context of the initial adoption of farming was not one of environmental pressure, then there must be some cultural reason; the vulnerability of Braidwood's proposals were his inability to suggest in what way culture might have been 'ready' 12 000 years ago, at the end of the Pleistocene, and unready at earlier times. The second question is how to integrate two views of the Neolithic that have been completely opposed to one another, each claiming to be the only proper way to approach the problems to the exclusion of the other. The first view, the processualist, ecological view, was first articulated in the later 1960s. Two American scholars, Lewis Binford and Kent Flannery, took quite a different view from that of Braidwood (Binford 1968; Flannery 1969). Lacking evidence of a driving force in climatic and environmental change, they opted for an ecological process in which an increase in population growth became the environ- mental pressure that pushed certain groups of hunter-gatherers. For our purposes, the processualist view may be characterised by Ofer Bar-Yosef, who has great authority within the field and international respect, and who has co-authored a more sophisticated synthesis in the light of the great volume of recently available data (Bar-Yosef & Meadow 1995). The other view may be characterised by the figure of Jacques Cauvin, who would shudder at the idea that he might be thought a post-processualist, but whose dismissal of processualist explanations puts him in the same camp (Cauvin 1994; 2000). Cauvin's account stresses the priority of the emergence of symbolic culture in a psycho-cultural transformation of the human mind. I am attempting to relate these two approaches to Neolithic phenomena, the adoption of farming economies, and what I call the facility for the symbolic construction of complex, multi-layered concepts of community, by relating them back to a single prior cause. In the terms used by Bruce Trigger in his essay on the rival epistemologies underlying schools of archaeological explanation, there is an epistemologi-cally based opposition between the processualist Jerf el-Ahmar. A vertical view of the subterranean communal building 1 at the centre of the early settlement, among houses of various shapes. 72 Neolithisation in southwest Asia - the path to modernity Jerf el-Ahmar. Communal building 1 was more than two metres deep and about 9 metres across. At least part of it had been roofed, presumably the cells, symmetrically arranged about an axis. At the end of the structure's use, a body was placed face down on the floor of the open area to the left, and the empty building was set on fire before the void was filled with soil. (positivist) and the post-processualist and other idealists' camp (Trigger 1998). And I am perhaps attempting a realist synthesis that follows Trigger's proposed solution. In that regard, I find that I am following a similar path to that recently outlined by Marc Verhoeven in his essay proposing 'a holistic approach to domestication' (Verhoeven 2004), and I shall return to this major paper when I have proposed my own synthesis. The prior cause to which I refer above will be described as a complex of interacting cognitive, social and economic factors. Key aspects of the complex are the emergence of larger social groups resident in permanent village communities, and the emergence of fully symbolic culture and cognitive faculties in human minds to match. It will be apparent that this complex of factors includes one that is universal (the co-evolutionary process of mind and culture) with others that are regional (how societies in southwest Asia constituted themselves and how they operated at the level of strategies of subsistence economics within the resources of the natural environment). Braidwood's killer question We can go right back to Robert Braidwood's work in the 1950s and early 1960s. Based on his multi-dis- dplinary research, he rejected the idea that Neolithic farming was a response to environmental pressures brought about by climatic change. Similar climatic and environmental changes had occurred repeatedly in the Pleistocene without bringing about the human response of adopting farming. He concluded that there must have been some cultural factor involved. Jacques Cauvin labelled that factor psycho-cultural, but was still unable to explain why such a psychological revolution in the use of symbols occurred at the end of the Pleistocene and the beginning of the Ho-locene. Finally, he published his proposed explanation as a hypothesis that would need to be debated and, discussed, and for which further evidence would need to be sought (Cauvin 1994; 2004). Lewis Binford's essay on Post-Pleistocene adaptations (Binford 1968) modelled a process that was not grounded in the archaeology of southwest Asia. But Kent Flannery drew upon his field research experience in southwest Iran, when he developed a closely comparable processualist model which he called the broad spectrum revolution (Flannery 1969). His ideas about the importance of the change to a broad spectrum hunting strategy and his neglect of the significance of stored plant foods mean that the model needs some modification, but it can be 73 Trevor Watkins made strong in the context of our current knowledge, mostly derived from Epi-palaeolithic sites in the southern Levant. For Flannery, the revolutionary moment occurred when hunter-gatherers began to focus on broad spectrum hunting and gathering (which we can redefine somewhat as harvesting and storing nutritious, hard seed plant species together with broad spectrum hunting), which implied the adoption of a more sedentary life. I prefer to call them hunter-harvesters. From that time in the Epi-palaeolithic, it only required pressure on finite wild food resources, and both Binford and Flannery argue for population growth as the force exerting pressure to adapt. Both Bar-Yosef, and Gordon Hillman with Andrew Moore depend upon the Younger Dryas reversal in the last millennium of the Epi-palaeolithic as the environmental force pushing communities to adopt cultivation and thus to initiate plant domestication (Bar-Yosef & Belfer-Cohen 1989; Bar-Yosef & Meadow 1995; Hillman 1996; Moore & Hillman 1992; Moore, Hillman & Legge 2000). Moore and Hillman are concerned essentially with the final Epi-palaeo-lithic period and the impact of the Younger Dryas, whereas Bar-Yosef, taking a deeper perspective starting from the end of the LGM, employs a push-and-pull model, in which there were alternating environmental phases that encouraged expansion or offered opportunities, followed by phases that exerted pressures requiring urgent adaptation. Bar-Yosefs model adds a social factor to the economic-ecological and environmental factors. Thus, the recovery from the LGM encouraged groups to focus on the increasingly available plant foods such as cereals and pulses. But then the Younger Dryas reversal pressed on final Epi-palaeolithic communities which had become larger sedentary groups, unable to opt for the flexibility of small-group mobility because the environment was Jerf el-Ahmar.

When the first communal building was destroyed, posts were removed and in one of the post-sockets a human skull was buried. too packed with other groups. But once again, similar climatic and environmental oscillations had happened earlier in the Pleistocene, and Braidwood's killer question still applies. Processualists like Bar-Yosef would probably respond that an inevitable process was set in motion when Epi-palaeolithic hunter-harvesters adopted the trend towards sedentism; at least in Bar-Yosef's view, the hunter-gatherer population had tended to concentrate at a higher density in the Levant in consequence of the LGM, and there was a trend among Epi-palaeolithic hunter-harvesters to live in larger, more permanent groups. Although the hypothetical concentration of hunter-gatherer populations in the Levant in the LGM remains speculative, the size and number of Epi-palaeo-lithic open sites and the expansion of the occupied area around the mouths of caves and rock-shelters in the Levant seems real. But this only pushes Braid-wood's question back to an earlier stage. Instead of asking why some groups began to engage in cultivation when they did, we now ask why they began to engage in harvesting and storing nutritious, hard-seeded crops, or why they sought to exchange their traditional mobility and fluidity of group membership for a trend towards sedentary life in permanent village communities. Once again, the opportunities offered by the recovery from the LGM (greater availability of wild cereals and pulses) would have occurred several times earlier in the Pleistocene, without the consequences that we observe in the Epi-palaeolithic. As far as concerns the adoption of cultivation leading to plant domestication, the force that exerted pressure to invest in the added labour of clearing the ground, digging and planting is contested. Some appeal to population growth leading to population pressure, while others believe that the Younger Dryas exerted a climatic-environmental pressure. In 74 Neolithisation in southwest Asia - the path to modernity truth it is practically impossible to decide between them, and one could add another hypothetical force in the shape of environmental degradation brought about by over-exploitation by intensive hunter-harvesters who were (semi-) sedentary. Whatever the source of the pressure for societies that had been practising the hunter-harvester way of life for millennia, living in relatively large and socially coherent communities, there was no way back to small-group mobility. The response of further intensification (cultivation) in the production of their food resources sooner or later resulted in domestication. The adoption of agriculture was the end of a process, not the beginning, as Flannery emphasised almost forty years ago. The questions of why and how Epi-palaeolithic communities were drawn or pushed to develop a way of life that was so different from that of their Palaeolithic predecessors remains. The nexus of Epi-palaeolithic social and subsistence strategies and the inevitability of farming We can agree that the Epi-palaeolithic was a critical period, and we should note that it was a long period. Many who write with a central concern for the beginnings of farming use the final Epi-palaeolithic of the Levant (the Natufians) as a prelude to their main period of interest. In the Epi-palaeolithic period, new kinds of social group emerged, and new subsistence strategies were adopted. We should not under-esti- Jerf el-Ahmar.

It was also subterranean, and the cavities where wooden posts that supported the roof have decayed can be seen behind the mud plaster of the wall. The interior had six large timber posts in a circle, and a series of large kerb-stones between the posts. mate the significance of the new, permanently sedentary communities that were an order of magnitude (approximately ten times) larger than earlier Palaeolithic groups. The new subsistence strategies involved storage of food resources, and the management and allocation of those resources required major changes in society and the development and adoption of new concepts. Ohalo II illustrates the Epi-palaeolithic process particularly well, and shows how early it began (Kislev, Nadel & Carmi 1992; Nadel, Carmi & Segal 1995; Nadel & Hershkovitz 1991; Nadel & Werker 1999; Piperno et al. 2004). It is a very early Epi-palaeoli-thic site, dating to the boundary between the Upper Palaeolithic and the Epi-palaeolithic (around 20 000 years ago in uncalibrated radiocarbon terms). It may represent a precocious group, but there is no reason to think that they or the ecological niche that they chose were unique. The site emphasises that the characteristics that are frequently associated with the final Epi-palaeolithic (Natufian) of the Levant were already effectively present or presaged at the very beginning of the Epi-palaeolithic period, many millennia earlier. The site of Ohalo II is usually submerged in shallow water at the southern side of the Sea of Galilee, but is partly exposed at times when water levels drop. There has been little or no subsequent erosion or disturbance, and there are extraordinary conditions of organic preservation. Ohalo II was a cluster of brush huts and hearths. There were also occasional burials among the huts. There is heavy stone equipment for grinding and pounding plant foods, and 120 species of plants, including cereals, large-seeded grasses, lentils, and vetches are evidenced. Traces of starch recovered from the surface of a grinding slab set in the floor of one of the huts have been identified as derived from the grinding of cereal (Piperno et al. 2004). The evidence of seasonality from the plant and animal and bird remains indicates year-round occupation. By the middle of the Epi-palaeolithic in the Levant there are examples of large, semi-sedentary or sedentary groups. In the last phase of the Epi-palaeo-lithic in the Levant (the Natufian) there were sedentary village communities numbering around 250 living 75 Trevor Watkins in the same place for many centuries, for example Abu Hureyra in north Syria (Moore, Hillman & Legge 2000), and Eynan ('Ain Mallaha) in north Israel (Valla 1991). Some of the phenomena that are so dramatic in the early Neolithic can be seen developing in the last phase of the Epi-palaeolithic period, and to a lesser extent in the earlier millennia. Situating the process in the context of cognitive and cultural evolution In response to what I called Braidwood's killer question - why then, why not earlier? - I want to situate these developments in new forms of social organization and new subsistence strategies in the context of the longer term evolution of human cognitive faculties. In particular, I am sure that the critical factor in long-term human cognitive evolution has been - and still is - the co-evolution of mind and culture. What I shall go on to argue here is that a particular stage in the co-evolution of mind and culture was essential if human social groups were to grow in size and permanence beyond the scale of earlier Palaeo- Jerf el-Ahmar.

One of the carved kerb-stones in communal building 2. lithic mobile, flexible hunter-gatherer groups. That stage was marked by the emergence of human minds fully capable of managing systems of symbolic representation beyond language, using symbolic material culture as a mode of 'external symbolic storage' (a key phrase from Merlin Donald, see below). That stage having been reached, over the last ten thousand years or so, the rich cultural environment has become the essential environment within which further (increasingly rapid) cultural evolution has taken place, rather than the physical environment, or much slower biological evolution. Before developing that case, I will very briefly outline some of the background in cognitive and evolutionary psychology and its application in archaeology and prehistory. Ahead of and separate from the recent explosion of publication on cognitive and evolutionary psychology and neuro-science, we should note the remarkable work of Peter Wilson on what he calls the domestication of society (Wilson 1988). Wilson, an anthropologist with a seemingly encyclopaedic acquaintance with the ethnographic literature, has written about hunter-gatherer settlement without apparently recognizing the relevance of his ideas for the prehistoric sedentary hunter-gatherers in southwest Asia. He differentiates between open and domestic societies. He argues that the adoption of a built environment had a profound effect on people's evolved social psychology. People's perception of their social selves was challenged. Buildings introduced privacy for interior space, as distinct from life in the public space. While challenging the evolved social psychology, living in what Wilson calls domesticated circumstances also offered exciting opportunities to use the built environment for symbolic representation (see Watkins 2004 or 2005 for a fuller discussion of Wilson's ideas, and a general survey of anthropologists, architects and social theorists on the symbolic potential of architecture). 76 Neolithisation in southwest Asia - the path to modernity Lesley Aiello (anthropologist at UCL) and Robin Dunbar (psychologist at Liverpool University) have been interested in the long-term evolution of the hominid mind, and the emergence of language (Aiello & Wheeler 1995; Aiello & Dunbar 1993; Dunbar 1992). They point to the unique trajectory of hominid evolution in developing a brain that supports larger social groups of inter-dependent individuals. Their studies conclude that the evolved human brain is biologically adapted for operating with social groups of a maximum number of 120 people. Dunbar has developed the theory that language evolved to facilitate gossip as a more efficient mode of communal grooming than the one-to-one grooming that serves in other sociable primate species (Dunbar 1996; 2004). Larger group sizes require advanced cognitive and cultural symbolising skills in order to frame the concepts that make large human societies work. Dunbar is one of a number of biologists, ethologists and psychologists who have worked on the question of how human societies overcome this biological barrier by using cognitive and cultural symbolising skills to formulate the powerful abstract concepts that underpin all modern social life (see, for example, Dunbar 1999). Boyd and Richerson, another anthropologist-psychologist team, have been working and writing on the theme of the co-evolution of mind and culture for a number of years (Boyd & Richerson 1982; Richer-son & Boyd 2005). They are just one example of those who work on the principle of mind-culture co-evolution. By means of culture, humans have learned how to build up, communicate and share huge bodies of information. By means of language and symbolic culture in general, human minds have developed extraordinarily and quite uniquely complex modes of storing abstract information. Merlin Donald is a Canadian psychologist, whose first major book, Origins of the Human Mind, has had a major impact on the thinking of a number of archaeologists (Donald 1991). Donald argues that humans evolved new modes of cultural communication, each of which has changed the way that human minds work. The emergence of a full, modern language faculty, in Donald's view, was the second stage in that evolution. The third and most recent stage was the emergence of what he calls 'external symbolic storage', by which he means the ability to read and write, to store and communicate accumulated knowledge, information, stories, music, or mathematics. In his more recent book, Donald has developed his theories much further, elaborating the argument that the very consciousness that we contemporary (western) humans enjoy depends completely on the cultural environment within which we have grown up from infancy (Donald 2001). Homo sapiens symbolic representation and the emergence of external symbolic storage Let us recapitulate the situation then. Homo sapiens emerged in Africa 160k years ago. Before 100k years ago, some Homo sapiens were present in modern-day Israel, and by 60k they had spread as far as SE Asia, colonising Australia by 50k. Some time around 100-50k years ago, a full modern language faculty evolved. Homo sapiens had therefore evolved the capacity for conceptualising systems of symbolic representation. And by 70k years ago the first buildingblocks of emergent symbolic material culture, such as incised pieces of red ochre, were present at Blom-bos and other sites in South Africa. A fully modern language capability is the second of Merlin Donald's three stages in 'the evolution of cul- Nevali (ori. One of the T-shaped monoliths from the "shrine" at the centre of the village. Some of these monoliths show that they were anthropomorphic, having arms, bent at the elbows, and hands with clearly indicated fingers. 77 Trevor Watkins ture and cognition' (Donald 1991). It is important to recognize that our modern languages - and their predecessors for the last few tens of thousands of years - are complex systems of symbolic representation (Deacon 1997). The definition of words as arbitrary signifiers for things signified is only a small part of the story, and the addition of grammar and syntax takes us only a certain distance further towards understanding the extraordinary cognitive complexity of symbolic representation that underpins the actual linguistic skills of all modern humans. Language does more than make indexi-cal links between signifiers and signified. In a system of symbolic representation, the tokens take their meaning in relation to one another. A sentence makes sense because statements take their meaning from the way that words are combined and interrelated. Language is a complex system of symbolic representation, but it is only one such system. Symbolic material culture offered people further opportunities for communication and storage. Now it is time to relate cognitive and cultural evolutionary theory to the prehistory of southwest Asia. In the Upper Palaeolithic, which is the sole territory of Homo sapiens, there are distinct changes from the Middle Palaeolithic. We can note that cultural phases that have been distinguished by archaeologists studying chipped stone industries follow one another at a very much more rapid rate than in the almost static Middle Palaeololithic. Now that radiocarbon dating is available, and sufficient dates assembled, it has become clear there were parallel and different cultural traditions within the Levant that were for the most part synchronous. In the Epi-palaeolithic period in the Levant, the pace of cultural change, and the Gobekli Tepe. The site is an artificial mound 300 m in diameter set on a bare mountain ridge. Each of the large structures was excavated into the mound and equipped with a pair of stones in the open centre, and more stones set into a "bench" around the sides. The oldest structures are the large, circular structures in the lower part of the plan, and they have each been rebuilt once or twice, each time on a smaller diameter. extent to which material culture was used to differentiate contemporary cultural groups, increases further. The early Epi-palaeolithic, for example, lasted a few thousand years, while the late Epi-palaeolithic was only two thousand years in duration, and three sub-phases have been distinguished by those specialising in the study of Natufian lithics. In short, we can begin to see how Homo sapiens was learning to use material culture to construct and maintain social identity. Indeed, the cognitive and cultural environment was becoming the evolutionary environment rather than the biological environment. 78 Neolithisation in southwest Asia - the path to modernity When we reach the early Neolithic, I have argued elsewhere that architecture became the means that communities used to make concrete their concepts of their village societies, their structure and their central focus on corporate rituals and shared ideology and iconography (Watkins 2004a; 2004b; 2006). In addition to its structural representation of a community, architecture can provide the arena within which people play out the dramas of social life, as well as the enactment of rituals that are concerned with the community's relationship with higher powers. In communities that numbered several hundreds and even several thousands, shared religious beliefs and practices were essential because what Susan Black-more (Blackmore 1999) calls religious 'memeplex-es', developing the idea of memes and meme-plexes as the cognitive equivalents of genes and gene-complexes that was first articulated by Richard Dawkins (Dawkins 1976; 1986), incidentally provide the justification for altruistic behaviours (Watkins 2003). We do not need to be concerned with the controversy over whether memes constitute another form of replicator in another evolutionary process of selection, as that is simply a vocabulary for articulating the results of Blackmore's social psychology research. The important point is that shared religious ideas go beyond shared beliefs and communal rituals, because they promote norms of behaviour and commend altruism. In communities that numbered several hundred and even several thousand individuals, the cognitive and cultural capacity to create and reproduce Gobekli Tepe. View down into structure D, the largest and earliest so far investigated. The two main monoliths remain embedded in the fill of the enclosure, but it is clear that they must be at least 5 m tall. Around the sides of the structure, T-shaped monoliths are set radially in the retaining wall. At the far side, the excavations have reached a stone "bench". Traces of the walls of earlier, larger forms of the enclosure can be seen at the far side. such abstract concepts as 'community' and 'neigh-bourliness' were essential. I have written elsewhere (Watkins, in press (a)) about the complexity of symbolic construction of community, a subject on which the anthropologist Anthony Cohen has concentrated over a number of years of study and thought (see Cohen 1985 for a succinct account). Epi-palaeolithic, and even more so early Neolithic, co-resident communities (I hesitate to call them villages) extended beyond kin-groups and beyond the scale for which the biologically evolved human brain were capable of managing the exponentially complex social relations (Watkins in press (b)). At a higher level, co-resident communities participated in active networks of similar communities, or some kind of interaction sphere (Watkins in press (a)) seeks to take up and modify Renfrew's idea of the peer polity interaction sphere - Renfrew 1986). In this kind of system of multi-layered networks, we can see how individual communities exchange items through a wider network (obsidian, marine shells, attractive stone or objects made of attractive stone), and share cultural ideas and practices. However, each community may articulate those ideas and practices in their own way. There were no text-books in circulation that defined how houses should be designed or how dead bodies should be treated. General observations of widespread cultural phenomena, such as the "the PPNB culture" (which I have criticized at some length in Watkins, in press (a)) or "the skull cult", break down as soon as they are examined in detail, because practices are usually not precisely replicated from site to site. There are domestic architectural forms that are found from site to site across a region. For example, Brian Byrd and Ted Banning have written about the pier-house in the later aceramic Neolithic of the southern Levant (Byrd & Banning 1988). And in southeast Anatolia, settlements had very large and substantially built houses, constructed from mud brick on stone and mud mortar foundations (Schirmer 1990). At one time, the foundations may consist of a series of square cells; at another time, they consist of clo- 79 Trevor Watkins sely set parallel walls. It appears that the sequence of architectural changes - from grids to sleeper walls - is replicated at different sites across the region. Intramural burials of bodies are found at many sites among or under the houses, in a special purpose building (as at ^ayónü Tepesi), or in clusters closely associated with the settlement. It was a practice that began with the first open village settlements of the Epi-palaeolithic period, but in the early Neolithic it became widespread and common. There was a parallel practice, especially in the Levant, of secondary removal of skulls, which were then curated, some with facial features modelled in clay or plaster, before being re-buried in caches. But there is a lack of systematic regularity; what has been found at one site is not quite the same as has been found at others. Across the Levant the intramural burial of certain people, and the removal and curation of skulls took place within the architecture and design of the settlement. The ceremonies and rituals and symbolism were designed to find their place within the already rich symbolism of the architecture, the burial ceremonies perhaps being played out within kin-groups, while secondary ceremonies with retrieved skulls may have involved the wider co-resident community (Kuijt 2000a; 2000b). There is now good evidence that settlements and their constituent buildings were laid out in accordance with some overall design. And there is now a series of settlements of the early Neolithic period that possessed monumental, non-domestic, specialpurpose, communal buildings, especially in southeast Anatolia and the north of the Syrian Euphrates valley (see Watkins 2004a or 2005 for a fuller discussion with extensive references). The first to be recognized was at a salvage archaeology site, Nevali ^ori, close to the Euphrates (Hauptmann 1988; 1999). In the centre of a quite small village of houses very similar to those of contemporary ^ayónü Tepesi (Ozdogan 1999) there was a sub-rectangular, sub-terranean structure (Hauptmann 1993; 1999). It had a stone "bench" around its walls, a lime plaster floor, and, in the centre of the floor area, a pair of tall stone pillars, only one of which was preserved. Similar stone pillars were set all around the perimeter in the bench. Through their lightly carved arms, bent at the elbows, and clasped hands the pillars reveal themselves as highly schematised anthro-pomorphs. With hindsight, it is now clear that there was a similar, subterranean building at ^ayónü, which also had a pair of tall, stone pillars. In southeast Anatolia we are beginning to see a regional in- Gobekli Tepe. One of the carved T-shaped monoliths from the earliest structure so far investigated.

Equally dramatic is the succession of communal, special purpose structures in the heart of the village at Jerf el Ahmar, on the Euphrates in north Syria, close to the border with Turkey. The settlement belongs to the earliest aceramic Neolithic period. In an open space at the centre of the community, there existed large-scale, fully subterranean buildings, which the excavator, Danielle Stordeur, calls 'communautaire, communal or public buildings (Stordeur et al. 2000, and see Watkins 2004a or 2005 for fuller references). The first in the series was by far the largest construction in the village, and it was certainly not a house. Stordeur believes that it was a communal 80 Neolithisation in southwest Asia - the path to modernity food storage facility that also accommodated ritual activities. At the end of its life, it was emptied, its roof was removed, a human head was placed in an empty post-socket, and a decapitated body was placed face down in the central area. Finally, the structure was destroyed by fire, and the void that it left was obliterated. The village shifted its topographic focus, and that first structure was succeeded by a second large, circular, subterranean building. This one had a bench all around its interior, and the bench had a decorated stone kerb in which the horizontal stones were articulated with large juniper posts, sheathed with elaborate plaster cylinders, supporting the roof. Even more remarkable is the site of Gobekli Tepe, near Urfa in southeast Turkey (Schmidt 2000; 2002; 2005 and see Watkins 2004a; 2004b for fuller references). It is a man-made mound of cultural debris mixed with stones and earth, constructed over many centuries on top of a bare limestone ridge. Large circular or sub-rectangular structures were built in cavities excavated in the mound. Each structure contained an axial pair of huge limestone pillars, exactly like those at Nevali gori. The largest structure so far investigated has the tallest pillars, which are at least 5 m tall. Around the perimeter of each structure is a stone-built "bench", and more pillars are set at right angles into the bench. Some of the pillars, like those at Nevali gori, have details that make clear that they are anthropomorphic. On their surfaces there are carvings in raised relief of a range of mammals, birds, reptiles, scorpions. Because of the lack of normal domestic settlement at the site or in its immediate vicinity, and because of the common features in the iconography at Gobekli Tepe and a number of other contemporary settlements, Schmidt has begun to discuss the idea that Gobekli Tepe was a ceremonial "central place" for communities living over a very wide area, an idea quite similar in general terms to that of Colin Renfrew in relation to the great Neolithic ceremonial structures of southern England (Renfrew 1973). What we are seeing in all sorts of forms, but particularly in the form of the architecture of buildings and the design of settlements, is external symbolic storage. Like language, it is a complex system of symbolic representation, but in material form. As remarked earlier, Donald originally defined the full emergence of external symbolic storage, the third and latest stage in the evolution of the human mind and culture, as being achieved with the development of alphabetic writing in the hands of the Greeks of the eighth and seventh centuries BC (Donald 1991). If he thought that the adoption of alphabetic writing in Greek constituted a significant point in the evolution of culture and cognition, it is not clear why other and earlier alphabetic writers (the Phrygians, the Phoenicians, or those who used alphabetic cuneiform at Ugarit, or other Semitic speakers using alphabets ancestral to the Phoenician in the second half of the second millennium BC) are passed over. For that matter, it is not at all clear what users of alphabetic scripts could write that those using hieroglyphic or hieratic scripts in Egypt, or the many peoples who used the cuneiform writing system developed in Mesopotamia, could not. The answer probably lies in what uses Greek writers soon began to find for their new writing system. But that is beside the point, for the real issue is whether non-language based systems of symbolic representation can be classed as external symbolic storage in Donald's definition of the term. Gobekli Tepe. Two of the monoliths. The stone on the left stood in a rectangular enclosure, the latest so far investigated. At a conference held in Cambridge, where Merlin Donald's ideas on the evolution of culture and cognition were tried and tested by invited archaeologists, Donald opened with a succinct account of the theme of his book (Donald 1998a). In his contribution Colin Renfrew proposed that Donald's third stage involving external symbolic storage was achieved in terms of systems of symbolic representation involving material culture among the early farmers of the Neolithic, some millennia before the earliest known effective writing systems (Renfrew 1998). At the end of the conference Donald responded to 8i Trevor Watkins what he had heard, and significantly modified his view on external symbolic storage in the light of Renfrew's contribution (Donald 1998b). Renfrew has developed his ideas about 'materiality' and 'the engagement of mind with the material world' (for example, Renfrew 2005). My own recent work has been concerned with the symbolising role of architecture in providing an arena for rich and complex multi-mode symbolic representation in communities of the early Neolithic in southwest Asia (Watkins 2004a; 2004b; 2006). Our modern academic preoccupation with books, journals, publications, and text should not blind us to the enormous significance of (non-verbal, non-literate) visuo-symbolic representation. In recent years, anthropologists, philosophers, social theorists, semiologists, and, of course, architects have all written enthusiastically about the capacity of architecture in particular to embody ideas, and to inspire, suggest and constrain human behaviour. It is easy to add to the cursory survey of the widespread recognition of the importance of architecture as symbolic representation in Watkins 2004a. For example, the distinguished architect Renzo Piano, in a recent interview in The Guardian newspaper (21 November 2005), said, "Architecture in some way has the duty to suggest behaviour. Places are the portraits of communities..." For those who wish to see how many twentieth-century philosophers, cultural theorists and semiologists have written about the cognitive importance of architecture, Neil Leach has collected pieces by twenty-three (Leach 1997). Building the Neolithic synthesis In the preceding sections I have argued that in the Epi-palaeolithic period the adoption of sedentary life in permanently co-resident communities coincided with and depended upon the development of a human cognitive and cultural facility with material systems of symbolic representation. For the first time in human history there emerged communities that were conspicuously larger than the biological human brain could cope with. Their size and stability depended on their ability to construct and maintain a variety of entirely novel, abstract concepts, and to concretize these in terms of the structure and architecture of their settlements. These communities were the first to realize the potential of the built environment to act as a complex system of material representation of symbolic information. Unlike books on the library shelf, the built environment is not a work of reference, but a world that we inhabit. It provides arenas for the rich symbolic representation of com- munity in all sorts of cultural modes. People had learned to create 'theatres of memory', cultural means of proclaiming continuity and memorialising the past that had formed them. Domestication had proceeded in other ways than that referred to by Peter Wilson (1988). I am sure that the major innovations to which Christian Jeunesse draws attention in his contribution to this volume, all consisting of the transformation of materials such as ceramics, lime plaster and heat-treated copper, are a part of the control and manipulation of the world in which early Neolithic communities delighted to explore and live. As Jeunesse says, these were further means of demonstrating control in a "technical system of domestication". And, as Hodder (1990) seems to intend, plant cultivation in fields and animal husbandry were further extensions of domestication, the bringing of elements (food plants and animals) of the natural world within the orbit and control of the domus. An expert survey of the most recent evidence (Nesbitt 2002) indicates that plant cultivation and intensive harvesting, leading to the recognizable domestication of several cereal species and a suite of pulses was practised in central parts of the hilly flanks of the Fertile Crescent by about 8500 BC (at the transition from the early ace-ramic Neolithic to the later aceramic Neolithic). We are now learning that, at almost the same time, animal husbandry was producing morphological signs of domestication in sheep, goat and cattle (Helmer et al. 2005). In short, the classic mixed farming economy, based on a suite of cereals and pulses and at least three ruminants, whether in response to some external pressure or as part of the assumption of control and management of their world, came into being in short order, and was embraced throughout the hilly flanks zone and beyond, into central Anatolia, in the following centuries. The combination of fully symbolic culture, permanent, large, sedentary communities, networking maintaining complex, multi-layered communities at different levels and scales, the control and transformation of natural materials, and the mixed farming economy were the foundations of a way of life that we can recognize as so like our own that we can call it 'modern'. The spread of the full Neolithic The term Neolithic has become problematic. It was associated with the appearance of people who lived in village-communities dependent on a farming economy. But in the Levant the Neolithic was also given specific material culture markers, in particular chip- 82 Neolithisation in southwest Asia - the path to modernity ped stone traditions that were different from those of the previous Epi-palaeolithic period. As we have seen here, the various components of society, economy, technology and culture that characterize the later aceramic Neolithic appeared at different times. And it deserves to be mentioned that the timing of the various components remains contentious. For our purposes, 'the full Neolithic' is the whole package that comes together in the later aceramic Neolithic period. After a relatively slow start over the several millennia of the Epi-palaeolithic period, when larger, sedentary hunter-harvester communities came into existence, the revolution in symbolic culture, the growth in co-resident community size, and the adoption of a number of transformative technologies, including the domestication of plants and animals, gathered pace in the early Neolithic period. The climax in the Levant is what is called the MPPNB (Middle PPNB) phase, about 8500-7600 BC. By that time, there was a human population that had colonised the island of Cyprus (Peltenburg & Wasse 2004; Swiny 2001), and they had introduced from the mainland the full suite of cultivated cereals and pulses, and sheep, goat, cattle, pig and fallow deer. These are the first signs of the expansive capacity of the Neolithic. In the final phase of the later aceramic Neolithic, between 7600 and 6900 BC, there began a major cultural and settlement dislocation that took different forms in different regions within southwest Asia. In the eastern part of the arc of the hilly flanks zone, settlement continued in the intermontane valleys of the Zagros, between Iraq and Iran, but remained on a relatively small scale. In the piedmont of eastern Iraq, and particularly on the alluvium in southwest Iran, the few early agricultural villages spawned a greater and greater number of settlements through the ceramic Neolithic and on through the Chalcoli-thic and Bronze Ages. The alluvium of southwest Iran has been fairly intensively surveyed, and Hole and Flannery chart the expansion of settlement in the Deh Luran plain, starting from the unique small village of Ali Kosh (Hole & Flannery 1968; Hole, Flannery & Neely 1969). Aceramic Neolithic settlements in the northeast segment of the arc of the hilly flanks zone (N Iraq) were confined to the hill country of the Jebel Sinjar (e.g. Qermez Dere or Maghza-liyeh - Watkins 1992) or the piedmont (e.g. M'lefaat - Kozlowski 1998). From the beginning of the ceramic Neolithic, however, farming villages sprang up in great numbers across the rain-fed plains of the Je-zirah, between the Euphrates in north Syria and the Tigris in north Iraq. The process in the north Levant is unclear, beyond stating the obvious - the aceramic Neolithic settlements in the Euphrates valley in north Syria were abandoned, and their immediate successors have not yet been identified. At least we can be reasonably sure that people moved away from the valley, because the accidents of salvage archaeology that located the aceramic Neolithic sites did not produce ceramic Neolithic settlements. In the southern Levant, the classic PPNB settlements of the Mediterranean woodland zone of inner Israel, the west bank and Jordan valley, and its southern extension beyond the Dead Sea into the Wadi Arabah, all failed during the late phase of the PPNB period. For a while, in that late PPNB phase and for a couple of centuries beyond, there was what has been labelled the 'megasite' phenomenon (Bienert, Gebel & Neef 2004). Certain settlements in highland Jordan (the best documented is 'Ain Ghazal) saw rapid expansion to 10 or even 15 hectares of dense domestic occupation. Rollefson has argued that the rate of expansion was too fast to be accounted for by natural population growth, and he therefore inferred inward migration from abandoned settlements in the Jordan valley and further west {Rollefson 1989; 1997; 2004). At the end of the late PPNB period and beyond, there was a trend towards small settlements, with quite ephemeral archaeological signatures, in the margins of the semi-arid interior. At the same time, the 'megasites' imploded and were abandoned, or, as at 'Ain Ghazal, continued only as a very small settlement of a quite different character. These new settlements are interpreted as small communities dependent more on herding than on cultivation, where a part of the population remained resident, while another part spent part of the year as nomads, pasturing large flocks of goats and sheep over extensive ranges. The picture in Anatolia (other than southeast Turkey, which is part of the central arc of the hilly flanks zone) is still unclear due to a lack of information across such a wide and environmentally varied region. In central Anatolia, there is the beginning of a cultural sequence covering the later aceramic Neolithic, pivoting about the famous site of ^atalhoyuk in the early ceramic Neolithic, and continuing on into the Chalcolithic. But there is a gap, both geographically and culturally, between the Konya plain and Cappadocian sequence and the next known sites to the southeast. Some have tried to claim the central Anatolian Neolithic as part of the expansion of the Levantine PPNB culture (e.g. Bar-Yosef & Meadow 1995 or Cauvin 1994, though somewhat modified in Cauvin 2000), but it is a case that does not stand 83 Trevor Watkins up to scrutiny. It is at least as likely that there was a parallel cultural tradition in central Anatolia that came more and more within the orbit of an intensely active Levantine and southeast Turkish interaction sphere as time progressed. The extent to which local domestication took place, or domesticated plants or animals were introduced from the Euphrates zone in southeast Turkey or north Syria remains unclear at present. The same problems beset the relationship between central and western Anatolia. There is no case for supposing that there was a spread of people practising farming from central to western Anatolia, since cultural traditions seem to be quite strongly regional. The Neolithic package of village-sized communities, with shared systems of symbolic representation, shared transformative technologies, and established mixed farming seems to spring into existence fully formed, only shortly after a different-looking cultural package had been put together in central Anatolia. In conclusion, there is evidence from various parts of southwest Asia of the spread of pastoralist/parttime farmers, or the rapid expansion of village societies across lands that were suited to mixed farming. But, if Anatolia is considered as the land-bridge between the heartlands of the southwest Asian early Neolithic and the Aegean islands, Greece and the Balkans, there is no plausible evidence of either demic expansion or cultural diffusion into central Anatolia, or from there to its western shores. The spread of the Neolithic to western Anatolia and into southeast Europe has a time-dimension in relation to the assemblage of the Neolithic package in the heartland of southwest Asia, but the mechanisms and processes involved in that apparent spread are likely to be quite complex. It seems possible that people in early Holocene communities (I am seeking a term that avoids the Mesolithic-Neolithic divide) were rapidly evolving the same cognitive and cultural facility with fully symbolic material culture that their neighbours in the heartland of southwest Asia had developed only a few centuries earlier. In some parts of southwest Asia, particularly in Anatolia, it is going to be difficult to disentangle exactly which elements of the Neolithic package were home-made, which were acquired by cultural borrowing and emulation, and which may have been carried by demic expansion. As far as the (Indo-European) language-and-farming hypothesis, or the 'wave of advance' model of demic diffusion are concerned, the lack of a simple, homogeneous pattern of spread from the Levant across Anatolia towards southeast Europe gives them a poor starting-point. Concluding discussion The main purpose of this contribution was to see if it was possible to bring together into a single account two components of the Neolithic that have tended to be viewed as exclusive of each other. The classic component of the beginning of the Neolithic has long been thought to be the adoption of mixed farming, and a large body of research over half a century has been devoted to identifying the domestication of plants and animals. In recent years, a very different approach has been proposed by archaeologists who argue for the Neolithic as a 'révolution des symboles', or a cognitive-cultural phenomenon involving the domus. I have argued that the trend towards sedentary village-communities and the trend towards dependence on stored plant food resources in the Epi-palaeolithic are two sides of a single coin. While these new strategies of settlement and subsistence may have been very well suited to the ameliorating environmental conditions after the Last Glacial Maximum, I made a point of showing that the trend had begun at the transition from the Upper Palaeolithic to the Epi-pa-laeolithic in the Levant. Thus, environmental opportunity cannot have been the driver of the trend. Rather, I have suggested that we should view the remarkable changes that mark the Epi-palaeolithic period as evidence of the way in which the cultural environment was becoming the ecological arena within which human cognitive evolution was developing. Throughout hominid evolution, the predecessors of Homo sapiens had tended towards larger social group size and greater social coherence and inter-dependence as adaptations to their biological environment. Once Homo sapiens had begun to master the cultural use of systems of symbolic representation (starting with language), they had the potential to construct and articulate the abstract concepts essential to the formation and maintenance of larger, more permanent and richer communities. In seden-tism, they found a fortunate conjunction between the symbolic construction of communities, and architecture and the built environment as the means to concretize their novel concepts. Sooner or later, as permanently co-resident communities grew in size and density in the landscape, for any of a variety of reasons, a greater investment of labour and intensification of food production became necessary. The growth in size of aceramic Neolithic communities contradicts the ergonomic view of the most ef- 84 Neolithisation in southwest Asia - the path to modernity ficient and economic use of labour when set against the resources gained. If ergonomics and efficiency were setting the parameters of co-resident community size, we would not find settlements of several hectares, representing populations counted in thousands. Rather, we would find small clusters of houses representing communities of minimal size scattered across the landscape. There were large settlements even before intensive cultivation and animal herding were adopted. But towards the end of the aceramic Neolithic, the very large settlements emphasise that it was the rich and intensive cultural environment that constituted their raison d'être and the engine of their further growth. Efforts to define some kind of settlement hierarchy have failed, and attempts to identify any kind of social hierarchy within settlements have remained at a purely hypothetical level. Finally, the end of small-group, hunter-gatherer mobility required a replacement for the social role of seasonal congregations and the occasional exchange of members and information; no small community is an island, whether it is a hunter-gatherer band of 25 or a sedentary community of 250. The formation of peer community interaction spheres allowed communities of whatever size to create higher-level commu- nities. Within southwest Asia the developed acera-mic Neolithic landscape consists of autonomous communities, the larger of which presumably had forms of internal social organization that were segmentary and non-hierarchical. And these communities participated in wide-ranging networks of cultural, social and economic interaction in which the non-competitive emulation of symbolic practices and symbolic entrainment tended to promote the intensification of exchange and convergence in systems of symbolic reference (cf. Renfrew 1986, and see Watkins in press (a)). In the last section of this paper, something of the complexity of the processes involved in the spread of the Neolithic package within southwest Asia was outlined. There is no room for a simple hypothesis of demic diffusion from the heartland of southwest Asia across Anatolia towards southeast Europe. Rather, it appears that indigenous communities with their own regional cultural traditions acquired the various elements of the Neolithic package partly on their own initiative and partly through their becoming increasingly engaged with already existing and very attractive peer community interaction spheres.

Several lines of evidence suggest that immigration played a major role in the process. It involved, however, both the actual movement of people and the active participation of the local population, and probably unfolded somewhat differently in different parts of the region. There is provocative evidence that the transition to farming occurred in a two-stage process. There was an initial stage of very rapid dispersal, perhaps by exploratory parties along the coast in the southern Adriatic. During the second stage, the eastern Adriatic littoral was probably colonized by farming communities, while the hinterland remained an agricultural frontier zone. IZVLEČEK - Začetek poljedelstva na področju Jadrana je tema, ki omogoča diskusije in nove sinteze. Predstavljamo dokaze, da je glavno vlogo pri procesu igralo priseljevanje. V regiji se je proces odvijal različno, vključeval je tako selitve ljudi, kot tudi aktivno udeležbo lokalnega prebivalstva. Dokazujemo, da se je prehod h kmetovanju odvijal v dvostopenjskem procesu. V prvi stopnji je prišlo do hitre razpršitve, morda izvidnikov, vzdolž obale južnega Jadrana. V drugi stopnji so skupine kmetovalcev verjetno kolonizirale obalne predele vzhodnega Jadrana, medtem ko je zaledje ostalo mejno področje kmetovanja. KEY WORDS - Neolithic; farming; Croatia; Adriatic; colonization Introduction Recent years have witnessed major advances in our understanding of the spread of farming in Europe, through the refinement of theoretical models (e.g. Price 2000; Thomas 1999; Whittle 1996; 2003), through the integration and comparison of archaeological, linguistic, and genetic evidence (e.g. Bellwood & Renfrew 2002; Ammerman & Biagi 2003), and through the characterisation of human diets and population movements by studying stable isotopes in human bones (e.g. Milner et al. 2004; Richards et al. 2003; Price et al. 2002). The eastern Adriatic coast lies along a major route into Central Europe from the southeast, but our state of knowledge about the spread of farming in the region remains relatively undeveloped. Maps offering sophisticated mo- dels for the spread of farming into Europe can leave the eastern Adriatic region blank (Barker 1985.Fig. 21; Renfrew 1987; Tringham 2000.Fig. 2.1; Whittle 1996.Fig. 8.2; Zvelebil & Lillie 2000.Fig. 3.1) or merge it with one of the neighbouring regions (e.g. Zvelebil & Lillie 2000.Fig. 3.4). In this brief paper we hope to put the eastern Adriatic region 'on the map' through a summarized review of the available evidence and the presentation of a new model of the spread of farming in the region (Fig. 1). Models for the transition to farming The transition to farming in Europe has been explained by a wide variety of models, ranging from a com- 89 Stašo Forenbaher, Preston T. Miracle pletely autochthonous process where local foragers turn to farming, to a completely exogenous process where foreign farmers migrate into Europe and replace the indigenous population (Barker 1985; Perles 2001; Price 2000). Claims for a completely independent domestication of plants and animals in Early Neolithic Europe have been thoroughly refuted on genetic (Jones 2002.94, 107, 130), morphological (Rowley-Conwy 1995; Zohary 1996.143-144) and taphonomic grounds (Zilhdo 1993), while models that rely primarily on migrating farmers (e.g. Am-merman & Cavalli-Sforza 1973; 1984) are now thought to underestimate the contribution of Meso-lithic foragers to the process, whether considered in terms of the modern-day gene pool (e.g. Richards et al. 1996; Richards et al. 2002; Jones 2002.160-161) or the indigenous adoption and transmission of parts of the 'Neolithic package' (e.g. Price 2000; Tringham 2000; Zilhao 2000; Zvelebil 1986; 2002). The Meso-lithic-Neolithic transition can no longer be considered in terms of a simple dichotomy between indigenous adoption and foreign migration. The major early domesticates were introduced into Europe at the start of the Neolithic. Since the crops could not have spread naturally into Europe, and domestic animals are very unlikely to have done so, we must consider at least some form of population transfer. Zvelebil and Lillie (2000.62) have recently listed six different forms of population transfer that may have been important in the transition to agriculture in Europe. We use these processes to frame our discussion of the transition to farming in the Eastern Adriatic; their definition and archaeological signatures are listed in Table 1. Much of the Adriatic literature still tends to see population change - that is, migration -lurking behind every major change in pottery style, let alone the introduction of the earliest pottery (e.g. Benac 1979-1987; Dimitrijevic et al. 1998). The migrationist view is echoed in syntheses by Chapman et al. (1996.259) and Biagi & Starnini (1999), who note the rarity of Late Mesolithic occupation in the region and an abrupt shift from wild to domestic animals at the Mesolithic-Neolithic transition. Others have undermined the unity of the 'Neolithic package' in the region, arguing that there is no necessary association between the appearance of ceramics and domestic plants and animals (Tringham 1971; Trump 1980). Tringham (1971) makes the strongest case for continuity of economic practices and lithic use from Late Mesolithic to Impressed Ware, citing evidence of wild fauna associated with impressed ceramics. More recently, Budja has proposed a model of 'Neolithisation' in the region that acknowledges the acceptance by the autochthonous population of a limited number of innovations, while rejecting any form of migration (Budja 1993.177; 1996.69; 1999).

Piecemeal adoption of Neolithic package by socially peripheral individuals. Leapfrog colonization Selective colonization of areas only marginally exploited by indigenous foragers, creating enclave settlements from which further dispersal of farming proceeds. Often movement by seafaring. Full Neolithic package moves; new settlements separate from Mesolithic; little interaction with indigenous people; abrput change; rapid spread Individual frontier mobility Individuals or small groups linked in social/economic exchanges between forager and farming communities. Direction and pace of change depends on existing social frameworks and communication routes and/or those established between forager and farming communities. Piecemeal adoption ofNeolithic package; innovations adopted within existing Mesolithic settlements; much interaction between indigenous and colonizing peoples Tab. 1. Expectations of different models of the Neolithization Process. Descriptions and expectations based on Barnett (2000); Zvelebil and Lillie (2000). Zvelebil and Lillie (2000.68-71) have recently suggested that 'Neolithisation' in Dalmatia involved the introduction of pottery into local forager communities during an 'availability phase' along the agricultural frontier. Similar models have been proposed by others, although each puts a different degree of emphasis on population movement and local adoption (Barfield 1972.204; Skeates 2000.171-172; Zvelebil 2001.2-6). Zvelebil's 'integrationist' model remains the most elaborate, taking into account social contexts of exchange (subsistence and otherwise) and intermarriage, and their effects on the movement of populations across agricultural frontiers. Before developing a new model for the 'Neolithisation' process in the eastern Adriatic, we summarize evidence about the pattern of change in the region. Farming and pottery in the eastern Adriatic The recognition of prehistoric farming sites in the eastern Adriatic region traditionally relies on the presence of pottery (e.g. Bagolini & von Eles 1978. 46; Batovic 1979; Chapman & Müller 1990.128, 132; Müller 1994; Skeates 2000.171; Sordinas 1969. 407), although such a simplified approach overlooks the possibility of hunter-gatherer groups obtaining pottery through exchange or adoption (Budja 2001. 40, 41). Over a decade ago, Chapman and Müller (1990.132) concluded that in Dalmatia, an integra- ted Neolithic 'package' consisting of four critical innovations - domesticated plants and animals, ceramics, and polished stone - was identifiable only at lowland open air sites. However, a reduced version of the Neolithic 'package' - domesticated animals, pottery and prismatic blade technology - is well attested at a much larger number of sites, many of which are caves, throughout the eastern Adriatic region. By contrast, convincing evidence of domesticated animals or pottery in Mesolithic contexts is extremely rare. It follows that, although far from perfect, pottery is still the most useful 'proxy measure' for exploring the spatial and temporal spread of farming in the eastern Adriatic. Recent work in caves shows some variety in the type of contact. The appearance of pottery may be associated with assemblages dominated by wild taxa (Cr-vena Stijena, Odmut, Zelena pecina, Mala Triglavca); in other caves there is a fairly even representation of wild and domestic taxa (Edera, Konispol, Azzura, Zingari), while domestic animals dominate the assemblages in a third group of caves (Pupicina, Mi-treo, Podmol, Vela spila, Spila Nakovana; for references and detailed discussion, see Forenbaher & Miracle 2006; Miracle & Pugsley 2006). Seeds of domesticated plants have not been reported from any of the recently excavated caves where the use of flotation to recover plant remains was standard prac- 91 Stašo Forenbaher, Preston T. Miracle tice. This holds true not only for Early Neolithic levels of those sites, but also for all later periods, when the cultivation of domesticated plants is not in doubt. Caves are rarely located near major tracts of arable land, but are often conveniently positioned for herders - either at, or on the way to, seasonal pastures. Such a contrast between open-air and cave sites has important implications for the process of 'Neolithisa-tion' in the region. The Mesolithic/Neolithic 'gap' A number of well-documented and dated northern Mediterranean sequences show a hiatus between the Mesolithic and Neolithic occupations of at least several centuries, if not several millennia (Biagi and Spataro 2000.48; Pluciennik 1997). The timing and duration of this Mesolithic-Neolithic gap is not synchronous, but varies widely from site to site. To examine this pattern in greater detail, we briefly discuss sequences from six sites in the Eastern Adriatic (Fig. 2, Tab. 2). In the Triestine Karst and Istria, the age difference between the youngest Mesolithic and oldest Neolithic dates at Pupicina Cave, Edera, and Ciclami is from 1100 to 1800 years. The similarity in timing and duration of the stratigraphic gaps is striking, at first glance suggesting that caves were not being visited by Late Mesolithic bands in this area, because of a change in settlement pattern, depopulation, or both. Other evidence, however, argues against a simple demographic explanation. Nine sites from the Triestine Karst are reported to contain evidence of Late Mesolithic occupation (Montagnari Kokelj 1993.74). Furthermore, at Benussi, there is a sequence of three radiocarbon dates associated with Late Me-solithic assemblages (Montagnari Kokelj 1993.70), the youngest of which overlaps the oldest Neolithic dates from Edera and Pupicina at 2 s.d. Late Mesolithic people were clearly in the region immediately prior to the first appearance of Neolithic pottery. In the south, only three sites have dated Late Meso-lithic and Early Neolithic components. Taken at face value, dates from Odmut Cave (Markovic 1985; Sre-jovic 1974) show a continuity of occupation from the latest Mesolithic to the earliest Neolithic. There are, however, problems with both the dates and the stratigraphy of Odmut (Forenbaher & Miracle 2006), and there may, in fact, be a gap between those layers with pottery and those without pottery of at least 300 years. At Konispol Cave, the dates suggest a gap of some 130 years between the latest Mesolithic and earliest Neolithic dates (Harrold et al. 1999), but the stratigraphy and fauna fill this gap (Russell 1998; Schuldenrein 1998). The open air site of Sidari provides provocative evidence of an in situ adoption of ceramics by indigenous Mesolithic people (Perles 2001). There is no stratigraphic break between the latest Mesolithic and the earliest Neolithic horizon, and the latter contains abundant plain ceramics, stone tools made using a 'Mesolithic' technology, and some sheep/goat. There is, however, a significant sterile layer between this 'earliest Neolithic' and 'Early Neolithic' (Impressed Ware) occupation of the site (Sordinas 1969). To summarize, three of six sites with dated sequences (Ciclami, Pupicina, and Odmut) show a stratigra-phic break and temporal gap between the Mesolithic and Neolithic. At Edera there is a temporal gap of about 1100 years, but not a stratigraphic break. The two sites (Konispol and Sidari) with dated stratigra-phic evidence of continuity come from the southern Benussi Edera Ciclami Pupicina Odmut Konispol Sidari 5000 5500 _ 6000 o m 6500 u ? 7000 7500 a o ! —n-0- 1 i Y ¿¿Hi 1 1 i Y i i , l'l [1 M 1 IN M II 1 t ii1 'iS 1 r ■ | !

How might we explain the recurrent gap in cave stratigraphies? Its time-transgres-sive nature, as well as the thick Late Mesolithic levels at several sites in both the northern and southern Adriatic, argue against a climatic cause of region-wide reduced sedimentation or erosion. In the Northern Adriatic the first pottery users visited caves that had long been abandoned. This abandonment more likely reflects a shift in settlement pattern (from caves to open air sites) than a decrease in population during the Late Mesolithic. In the two dated sequences from the south, in contrast, there appears to be a continuity of occupation from the Mesolithic to Neolithic; and pottery use appears to have been incorporated into a pre-existing strategy. We suspect that this geographic contrast in the continuity of occupation from the Mesolithic to Neolithic may correlate with a contrast in the processes involved in the adoption of pottery and farming in the two regions. The introduction of pottery into the Adriatic Since Chapman and Muller's (1990) discussion of the pattern of radiocarbon dates for the Eastern Adriatic Neolithic, there has been a slow but steady accumulation of radiometric dates from secure contexts (Fig. 3, Tab. 3). The basic pattern that they identified still holds; after the initial appearance of pottery on Corfu at the mouth of the Adriatic at ca. 6500 Cal BC, dates become progressively younger as one moves up the coast towards the northeast to the head of the Adriatic, where pottery makes its first appearance 1000 years later at about 5500 Cal BC. Poorly fired, mostly plain pottery appears just south of the Straits of Otranto around 6500 BC (Sordinas 1969. 401, 406, note 14). It is roughly contemporaneous with, or only slightly later than, the earliest pottery found elsewhere in Greece (Perles 2001.9495). Around (or soon after) 6200 BC, a characteristic pottery style known as Impressed Ware emerges somewhere on the northern Ionian coast (possibly, on Corfu), and then spreads rapidly into the immediate hinterland (Albania), up the Adriatic to southern Dalmatia, and to southeastern Italy (Sordinas 1969; Skeates 2000). Over the next few centuries, Impressed Ware spreads deeper into the Adriatic, reaching northern Dalmatia by around 5900 BC, 93 Stašo Forenbaher, Preston T. Miracle and southern Istria by around 5750 BC. By that time it also reaches the deep hinterland of the eastern Adriatic (Marko-vie 1985). On the Italian side of the Adriatic its spread is somewhat delayed, reaching Abruzzo by 5750/5650 BC and Eastern Romagna by 5300 BC (Skeates 1994). Impressed Ware was the earliest pottery to appear almost throughout the length of the eastern Adriatic (Batovic 1979; Müller 1994). It seems, however, that it never reached the extreme north-western part of that region - northern Istria and the Triestine Karst (Forenbaher et al. 2004; Veluscek 1997). Some time around 5600 BC, a new style known as Danilo (or Danilo/Vlaska) emerges in the eastern Adriatic, where it soon replaces the Impressed Ware. Only at that point does Danilo-like pottery reach the interior of Istria and the Triestine Karst, and as far to the northwest as Sammardenchia in Friuli (Pessina & Rottioli 1996. 85, Fig. 6), where it merges with pottery styles derived from western Adriatic traditions. Calibrated radiocarbon dates allow us to consider the rates at which the pottery was spreading (Fig. 4). It took about 1000 years for pottery technology to move from Corfu to the Triestine Karst, a straight-line distance of roughly 875 km. This gives a rate of spread of about 0.9 km/year, which is close to the 1 km/year rate of the 'wave of advance' proposed by Ammerman and Cavalli-Sforza (1973). If, however, these were sea-faring people, for whom there is good evidence (Bass 1998; Forenbaher 1999), 1 km/year seems like a fairly leisurely pace. If, on the other hand, we consider the spread of Impressed Ware in some detail, a somewhat different pattern emerges. It took only about a century for Impressed Ware to move from Corfu to Korcula, a straight-line distance of roughly 460 km. This gives a considerably quicker rate of spread of about 4.5 km/year. Moving further to the north, it took about 300 years for Impressed Ware to move from Korcu- Fig. 3■ Calibrated radiocarbon dates associated with Early and/or Middle Neolithic pottery from sites from Corfu, the Tavoliere, Albania, Montenegro, Dalmatia, Istria, and the Triestine Karst.

The rate of spread has fallen to only 1 km/year. Furthermore, the early dates from southern Dalmatia come from caves only, while those from northern Dalmatia and Istria come from both caves and open-air sites. From these admittedly scanty data, we suggest that the spread of the Neolithic along the eastern Adriatic was not a smooth and continuous process. There may also have been a shift in settlement from short-term visits to caves in the very earliest phase to the longer-term occupation of open-air sites in the later phase. The processes of change The archaeological record thus testifies to temporal and spatial variability in the cultural practices associated with the first pottery and the apparent speed with which it moved up the Adriatic, whether piecemeal or as part of a package. It suggests that several different processes were important across the Meso-lithic-Neolithic transition along the eastern Adriatic. Beginning with the southern edge of the Adriatic, Si-dari and Konispol provide the most compelling evidence of the adoption of pottery and domestic animals by small groups of seasonally mobile 'Mesoli-thic' hunter-gatherers.

Radiocarbon dates associated with Neolithic pottery assemblages from Corfu, the Tavoliere, Albania, Montenegro, Dalmatia, Istria, and the Triestine Karst. 95 Stašo Forenbaher, Preston T. Miracle unique to the region. The presence of only parts of the 'Neolithic package' and their appearance within an existing Meso-lithic site suggests adoption through social interaction and exchange - probably 'individual frontier mobility' (Tab. 1). These cultural novelties were not moving between Mesolithic populations. Neither pottery nor domestic animals are present only 35 km away across the Strait of Corfu in Late Meso-lithic layers dating to ca. 65006200 BC at Konispol Cave. It is only with the appearance of Impressed Ware that the Neolithic starts to move in the region. The earliest radiometrically dated Impressed Ware appears at Sidari Layer C top at about 6200 BC. There is little indication, however, of cultural continuity between this and the underlying Layer C base; there is a major stratigraphic and chronological gap (ca. 300 years) between them. Impressed Ware at Sidari is associated with the full suite of domestic animals and other changes in lithic technology and typology (Perles 2001.49-50). The identity of the inventors of Impressed Ware style remains elusive. Were they from the indigenous population, who perhaps acquired or invented new pottery making techniques during the several centuries when they were not occupying the site, or were these new immigrant agropastoralists from the southeast, who brought pottery with them? We doubt that there will be a satisfactory answer to this question any time soon. Rather, we think it is more productive to try to understand how and why Impressed Ware started to move. The coastal distribution of Impressed Ware sites and their presence on most of the eastern Adriatic islands, including a number of isolated islets far from the mainland (Bass 1998; Forenbaher 1999), indicates clearly that maritime communication was the key ingredient of its dispersion. Seafaring was not necessarily a Neolithic invention. There is indirect evidence of pre-Neolithic (11th Millennium BC) seafaring from Franchthi Cave (Perles 2001.28, 35), as Fig. 4. Model of the spread of farming and herding in the Eastern Adriatic region. Black, solid lines: first phase of rapid 'leapfrog colonization' associated with Impressed Wares. Grey lines: second phase of slow 'agropastoral expansion' associated with Impressed Wares. White lines: third phase of 'agropastoral expansion' associated with Danilo/Vlaska pottery. Black, dashed lines: adoption of herding and farming through 'individual frontier mobility'. well as the Mesolithic colonisation of Corsica and other Mediterranean islands during the early Holo-cene (Costa et al. 2003). The radiocarbon dates indicate that Impressed Ware and domestic animals took less time to move almost 500 km up the Adriatic to the Middle Dalmatian islands than they took to move 35 km across the Strait of Corfu to Konispol Cave. The former pattern is compatible with the model of 'leapfrog maritime colonisation' by small seafaring communities (Zilhao 1993 37, 50; Zvelebil 2001.5), although the lack of dated open-air sites (permanent villages) associated with the earliest Impressed Ware in the southern Adriatic undermines the fit. We may have early Neolithic 'colonists' without evidence of their colonies. Without more information about the Late Mesolithic in the coastal region it is difficult to exclude an alternative hypothesis: that local Mesolithic foragers acquired pottery and other innovations, and then dispersed them by sailing up and down the Adriatic. 96 The spread of farming in the Eastern Adriatic Beyond the coastal strip in the southern Adriatic and Albania, Impressed Ware and other innovations were introduced through contact between agricultural and hunter-gatherer groups. Radiocarbon dates suggest a piecemeal adoption of parts of the 'Neolithic package' at Konispol, Odmut, Crvena Stijena, and Zelena pecina, slightly after the initial spread of Impressed Ware up the Adriatic. Some of these sites are located in areas unsuitable for agriculture, in remote parts of the hinterland separated from the coast by high mountain ranges; others overlook valleys with good agricultural potential. Only at Konis-pol do we have detailed enough data to discuss the process of adoption of pottery and domestic animals. Russell (1998.149) suggests that cattle were relatively important in the transitional assemblages at Konispol and that these animals may have been provided to the hunter-gatherer inhabitants as bride-wealth. Cattle and other domestic animals may have also been important in feasts. Without further information about the social contexts of consumption and use of food and pottery, the process by which these novel resources were adopted by the Mesoli-thic hunter-gatherers remains vague. For the time being, a variant of Individual Frontier Mobility would appear to be the most likely process. After 6000 BC, Impressed Ware made its way up the northern Adriatic, reaching southern Istria by ca. 5750 BC. Along the way, our Impressed Ware potters started to live in open-air sites that look like more permanent villages. Faunal assemblages, whether from caves or open-air sites, are dominated by domestic animals. Direct evidence about plant foods is scarce, although site locations show a preference for land suitable for agriculture. Although the evidence is patchy at best, we suggest that it is only at this time that we have the assembly of the entire 'Neolithic package'. Why did the pace of pottery adoption change after 6000 BC? The northern Adriatic may have supported larger and more successful groups of native hunter-gatherers, who resisted the immigration of farmers. Some evidence for this model comes from the large number of Mesolithic sites at the head of the Adriatic, and the delay in the appearance of agriculture in the region. On the other hand, the relative population densities might have been reversed (relatively lower in the north and higher in the south), suggesting that social leveling mechanisms in relatively small indigenous populations in the northern Adriatic undermined the acquisition and spread of prestige items like pottery and domestic animals. Re- gardless of whether Impressed Ware was carried by migrating farmers or passed among resident hunter-gatherers, the density and social organization of Late Mesolithic people is key to our understanding of the process. A two-stage model of dispersal We are thus proposing a two-stage model for the dispersal of Impressed Ware, in which there is an initial stage of pioneer exploration followed by a later stage of colonization (Fiedel & Anthony 2003). The first stage occurs rapidly and is limited to the islands and the coastal strip of the southern Adriatic. Rather than establishing permanent settlements, these people may have made short-term, seasonal camps in caves and the open-air. They apparently brought domestic animals with them, and may have seeded islands with flocks in anticipation of future visits. The Impressed Ware 'pioneers' rapidly explored the southern Adriatic, establishing contacts with indigenous hunter-gatherer groups in the hinterland, and probably relying on these native groups as a source of information and perhaps marriage partners. The initial Impressed Ware occupations at Vela Spila and Gudnja may be evidence of these first 'scouts'. During the second phase of Impressed Ware expansion, settled farmers became established. There was less reliance on native hunter-gatherers for information and other resources, and in any case, those that held on in the region had probably been decimated by the loss of personnel to farming, disease, through marriage, or conflict. Exceptions might have been the hinterland of Montenegro, where important elements of the foraging lifestyle continued into the Middle Neolithic (Crvena Stijena) or even Late Neolithic (Odmut). Farming eventually reached the head of the Adriatic about 5600 BC, now associated with Middle Neolithic Danilo/Vlaska pottery. Conclusion Archaeological evidence suggests that immigration played a major role in the introduction of farming into the eastern Adriatic. This is not to say that this was a one-sided affair in which indigenous foragers were passive recipients. It must have been a complex process that involved both the actual movement of people and the active participation of the local population. There is no reason to believe that this process unfolded along identical lines throughout the region. There is provocative evidence that the transition to farming occurred in a two-stage pro- 97 Stašo Forenbaher, Preston T. Miracle cess. An initial stage of very rapid dispersal, perhaps by exploratory parties along the coast in the southern Adriatic, was followed by a second stage, during which the eastern Adriatic littoral was probably colonized by enclave-forming farming communities. The hinterland, and perhaps also parts of the coast, remained an agricultural frontier zone for a while. -ACKNOWLEDGEMENTS- This research was supported in part by the Ministry of Science and Technology of the Republic of Croatia, project MZT-0196004.

Early jar burial development in south-east Europe displays two distinct chronological levels: an early Neolithic core area in the Struma and Vardar valleys and the western Rhodope, and later, late/final Neolithic and/or early Chalcolithic - depending on local terminology - manifestations 'scattered' in various places in the study area. It is the early chronological level of jar burial distribution that will be considered here in relation to the first expressions of these mortuary practices in Central Anatolia, in order to throw some light on the specifics of their origins and variability. IZVLEČEK - Tipičen element zgodnjega simbolizma poljedelcev, pokop v posodi, se je pojavil na začetku procesa neolitizacije jugovzhodne Evrope. Zgodnji razvoj teh pokopov kaže dve kronološki stopnji: zgodnje neolitsko jedrno območje v dolinah rek Strume in Vardarja ter zahodnih Rodopih in mlajse, pozno/končno neolitske in/ali zgodnje bakrenodobne pokope - odvisno od terminologije, razpršene v regiji. V razpravi analiziramo najstarejše žarne grobove in jih v kontekstu izvora teh grobnih praks, primerjamo s pokopi v centralni Anatoliji. KEY WORDS - jar burials; early chronological level; southeast Europe; Central Anatolia Introduction: grave pit interpretations The ordinary pit is reasonably conceived as the single archetype of burial structure. It is obviously the simplest, but sufficiently definite form of fulfillment of the idea of disposing of human remains through burial, which developed after the original covering of the deceased on the ground with grass, tree branches or hides, and later with soil and/or stones. Many of those who have explored southeast European Neolithic burials believe that the grave pit and hence the very burial of the dead has not been paid special attention; they illustrate their case with examples of refuse pit usage favanavic 1967.13; Gara-sanin1973-27; Brukner 1974). It was even proposed that intramural burials had not belonged to local community members, but to their defeated enemies, and that the dead of the respective Neolithic community were buried in extramural cemeteries. In my opinion, the main reason for the wide circulation of this thesis in one form or another is the fact that most Neolithic burials lack grave goods and that the pits' backfill is the same soil of the cultural deposit, which contains various artifacts. Hence the seemingly reasonable conclusion that the dead were 'thrown away', but not buried. Such an argument is unacceptable, especially if one considers the fact that, at least for the area of southeast Europe, it is based on the incorrect interpretation of grave pits as refuse pits. Certainly their backfill is often identical with that of refuse pits, and the difference between them is rather 'archaeologi-cally elusive'. The presence of a great number of sherds and animal bones does not automatically transform pits into refuse pits, as is obvious, for in- 101 Krum Bacvarov stance, from two 'ritual pits' from Parta I (Resch 1991; see also the analysis of the so-called structured deposition in Chapman 2000). Moreover, there is the case with the re-use of already existing pits, for instance pits left from clay digging, as at Ajmana in the Danube Gorges (Stalio 1992.65-66), and of silos, as at Nea Nikomedeia in western Macedonia (Rodden 1962.286). On the other hand, there are unquestionable examples of 'rejection' or 'isolation' of the deceased, as at Vaxe-vo in the Struma Valley, where the situation unambiguously demonstrated that the dead body had been thrown into the pit (Cholakov 1991.231-232, Fig. 1; Chohadzhiev 2001.170-171, Fig. 10). Quite instructive in this respect is burial 285 at ^atalhoyuk, which is the only one outside the buildings. Anthropological analysis shows pathological changes suggesting that the deceased young man probably suffered all his life from a serious disease which was the cause of his external deformities (Molleson et al. 1998). And last, but not least, the 'refuse pits' interpretations always fail to consider burials beneath house floors, which are especially valuable as arguments against these allegations. These burials' position does not allow one to suppose that they belong to 'rejected' individuals; neither are they limited to infants and children only in order to be explained as 'sacrifices', although it is not very clear either why these so-called sacrifices should be related to children. In this sense, it is worth remembering that the burials in the Anatolian Neolithic and early Chalco-lithic are most often not interpreted as belonging to marginal members of the local communities, and they generally correspond to the southeast European burials, both culturally and formally. The grave pit was considered in the same semantic context as the contracted position of the dead body. If the symbolic meaning of the body position is generally assumed as embryonic, it is completely reasonable to view the pit as the womb of the female divinity, even though this 'Mother-Goddessist' interpretation would probably be considered by many as outdated. The later megalithic tombs in northern Europe had similar significance; their entrance was viewed as a divine vagina, and the bringing of the dead body into the tomb imitated the act of impregnation (Grdslund 1994.22-24). Of course, burial structures of a semantically similar plan existed as early as the Starcevo period at Zlatara in Srem and at Vinca-Belo Brdo (Vasic 1936.9-17; Lekovic 1985. 159-161), and are a logical development from or- dinary pits. It is clear that, as a whole, the mortuary rituals reproduced the mythological act of creation, and the burial features played a fundamental role in them. Jar burials: early types and distribution An additional argument here is the group of graves in southeast Europe where the human remains were buried in clay pots. This practice was common in the Levant, both in earlier and contemporary contexts. The clay pot itself was also considered as a womb, but this symbolic aspect had been secondarily stressed in burial contexts, as is the case with the later Alishar Huyuk, where two of the urns were modelled with conical 'breasts' (Schmidt 1932.72). In its symbolic aspect of container, the womb of the female divinity or the mother goddess, if one should use the convenient term, the pot - without respect to the material - played a significant role in many rituals, all the more so in historical times. One specific feature of the burial in clay pots in the Neolithic, which differentiates it from the evolution of this practice in later periods, is the re-use of vessels, which originally had a different function and had not been made especially for burial. The original purpose - both real and symbolic - of clay pots from Neolithic sites remains unknown, but the tradition of burying in silos can be traced back to the Levant. It is worth considering the burials at Ajmana and Nea Nikomedeia once again and especially the original purpose of the grave pits: the former was a pit left from clay digging, and the latter was an old silo. Certainly one should not belittle the expedient aspects of re-using pits but it is evident that there is a semantic similarity to the clay pot on the one hand, and to grain, on the other. The burial in a vessel/pit - which is a container/womb - obviously reproduced the mythological act of creation; it confirms again the symbolic relationship between grave/death/burial and grain/fertility/rebirth (Bacvarov 2003.129133). In this sense, on a practical level, these clay pots were originally used as food containers, as cooking pots or for other purposes, and were later re-used in burials as death-containing vessels; on a symbolic level they were originally used as containers of culturally transformed or transforming matter, or matter prepared for transformation in the future, and were later re-used in burials as 'birth-giving' vessels. All these were different aspects of the same concept in the religio-mythological beliefs of early farmers. Nevertheless, burials in clay pots do not constitute a homogenous group, but can be separated into 102 Early Neolithic jar burials in southeast Europe> a comparative approach three different types, each with specific features. I will consider them here with respect to their origins and territorial distribution. A total of four cases of individual formal inhumation in a clay pot - or typical jar burials - have been found in southeast Europe: two at Kovačevo in the Struma Valley, one at Rakitovo in the Rhodope and one at Anza in the Vardar Valley (Lichardus-Itten et al. 2002.116, 127, Pl. 9, 1-2; 10, 1; Raduncheva et al. 2002.35,150-151, obr. 24/2,12; 81/3; Gimbutas 1976.397, Fig. 242, Pl. 47). All four complexes date back to the early Neolithic: the first three burials belong to the Karanovo I culture, and the fourth belongs to the Kremenik-Anzabegovo culture. The burial from Rakitovo was found near the western wall of a house, beneath the floor, and the other three graves were discovered between houses. All vessels were pots, one of which - that from Kovačevo - had a clay lid. The globular pithos from Anza had four broken handles and a broken bottom, most probably intentionally. Grave goods were found only in the Rakitovo burial: a flint tool and lumps of red ochre. The skeletal remains belong to newborn or stillborn infants buried in a contracted position. Only one of the Kovačevo skeletons was explored in situ by an anthropologist and in this case the position was found to be contracted on the right side, with the head aligned to the north. It is worth mentioning that a total of seven infant or children burials were excavated at the same site, and only two of them, belonging to stillborn/newborn babies, were interred in clay pots, whereas the rest belong to children buried in ordinary pits. In one case the dead child was wrapped in a thick cover, probably a mat or possibly a sack. As far as I am concerned, this practice had no parallels in the neighbouring areas, neither culturally nor chronologically. The closest analogies are three jar burials from Kosk Hoyuk and Pinarbasi-Bor in Central Anatolia, which were also found beneath house floors like the Rakitovo grave, and belong to the Anatolian late Neolithic/early Chalcolithic (Yakar 1991. 192). On the other hand, however, this tradition probably originated in the Levant, where it had already become quite common and was related, for instance, to the archaic Hassuna culture and the Tell Sotto culture. Six jar burials at the eponymous site at Tell Sotto and one burial at Tell Hazna II are especially instructive (Bader 1989.132-135, Tab. 47/1-2; Munchaev et al. 1993.27-34). The strong influence of Levantine traditions on the life and culture at Kosk Hoyuk, especially on mortuary practices, manifested itself in the local variant of the 'skull cult' which was observed at that Anatolian site. The earliest 'decorated' skulls of this kind were found at Jericho. The skull from Kosk Hoyuk, however, was found in Layer III, which resembles the late Neolithic at ^atalhoyuk, whereas the skulls from Jericho are of a much earlier date. The second type comprises only one Neolithic grave related to a secondary collective burial. It was discovered in Layer III at Tell Azmak in Thrace and belongs to the early Neolithic Karanovo I culture. The clay pot contained several skulls (the excavator does not give the exact number) as well as separate bones (Georgiev 1966.9-10). This find remains unique and could be related only to the secondary collective burials in ordinary pits, from Layer II and IV of Tell Ka-ranovo, for instance (Bacvarov 2000). This is not the case with the last type, known from as many as six sites in southeast Europe and related to cremation burial. A large clay pot containing the burnt bones of a child was found close to the oven in a house from the early Neolithic layer at Tell Az-mak. The pot was very probably buried beneath the house floor, but this is not explicitly stated in the only source available: the ground plan of the house published in 1972 (Georgiev 1972.17, Abb. 4). This burial is not unique in the southeast European early Neolithic, although it is the only one found in Thrace. Cremation burials in clay pots were found in the late Starčevo layer at Vinča-Belo Brdo and at the Koros site of Gorza in the Tisza Valley (Vasic 1936.182; Ga-zdapusztai 1957). The burials from Vinča and Gorza formally correspond to the Azmak complex; the calcined bones were interred in clay pots. Cremation was known as a ritual practice as early as the Upper Palaeolithic, but the bones were often only burnt superficially (Binant 1991.145-146). Such burials were also found at Epipaleolithic sites, although rather occasionally. However, it is possible that the separate burnt human bones were not recognized and collected together with the animal bones, as is the case with the Franchti cave, where skeletal remains of about thirty individuals were recovered after careful sieving of the soil and analysis of the animal bones (Cullen 1995.274). More numerous examples of cremation burials in pots come from the late Neolithic layers at Souphli Magoula and Plateia Mago-ula Zarkou in eastern Thessaly (Gallis 1975; 1996a; 1996b). At Souphli, besides the charred skeletal remains buried in round pits with grave goods and belonging to the early Neolithic Protosesklo culture, 103 Krum Bacvarov seven pots containing charred bones were found to the south of the Magoula, belonging to the Tzangli-Larissa phase of the Dimini culture. The cemetery of Plateia was excavated at less than five hundred meters from the site; it contained more than seventy cremation burials in clay pots covered with other vessels, in one case a zoomorph. The grave pits were surrounded with stones, or in some cases the bottoms of the pits were covered with a layer of pebbles. Smaller vessels were buried as grave goods. There are many different interpretations of the Neolithic cremation burials, ranging from purification to ways of releasing the spirit. Ina Wunn assumes that the burials from Souphli and Plateia are clear indicators of a belief in the existence of a soul which detaches from its earthly shell through cremation, thus facilitating its transformation into another existential form (Wunn 2001.134-137). I cannot agree with the idea that these practices were the result of the elaboration of concepts of an afterworld, because they appeared too early. It is rather that the cremation burial was considered in the same religio-mytho-logical context as inhumation in a contracted position, but in an aspect more closely related to fire. This conclusion is supported by the fact that in most cases the cremated human remains were interred in clay pots, whose symbolic meaning has already been considered here. The position of the Azmak burial near the oven should be viewed in the same light. Certain additional hints to the interpretation of the symbolism of cremation burials in clay pots are found in the fact that the complexes at Tell Azmak and Gorza are earlier, whereas the graves at Vinca, Souphli and Plateia are of later date. Moreover, the Azmak burial - and probably the burial from Gorza -was of a child, which perhaps relates it more closely to formal individual inhumations than to the typical late Neolithic cremation burials; it should be noted also that it was found beneath a house floor. Instead of a conclusion: Late/Final Neolithic and Chalcolithic development Jar burial continued to be practiced in the late/final Neolithic and the Chalcolithic of southeast Europe. Six more burials were found beneath house floors or outside houses. A new element here was the use of bowls to contain or cover the infants' bodies, while in the early Neolithic cases, only pots had been used. Such a burial of a neonate, covered by a deep, dark-burnished bowl with channelling was found at Tell Ezero in Upper Thrace and date back to the late Neo- lithic Karanovo III period (Georgiev etal. 1979.46). They are similar to the final Neolithic cases at the tells at Mandalo in northern Greece and Lerna in Argolis, where two more burials were uncovered under house floors, in an open undecorated bowl and a patterned beaker, respectively (Caskey 1957.159). However, the old tradition of burial in pots also survived in the same areas it had been practiced before, as is suggested by the infant burials at Polgar, site 7 (Alfold Linear Pottery Culture) in the Great Hungarian Plain, and in the Kouveleiki cave in Laconia, Greece (Papathanassopoulos 1996), as well as the burials at Rachmani in Thessaly (Wace and Thompson 1912). Nine more jar burials were found in the cemeteries at Moragy-Tuzkodomb (southern Transdanubia), Du-rankulak (Dobruja), and Kephala on the Cycladic island of Keos, which belong to the late Neolithic Leng-yel culture, Hamangia III and the final Neolithic, respectively (Zalai-Gaal 2002; Todorova 2002; Fowler 2004). -ACKNOWLEDGEMENTS- An early draft of this paper was presented in 2003 at the international symposium in Stara Zagora, Bulgaria, and was later published in its proceedings.

Full, non-hostile interaction between hunter-gatherers and farmers in the Iron Gates region is proposed for the mid- 7th millennium calBC, followed by hunter-gatherer encapsulation at the end 7th millennium calBC. The lack of archaeological records on the Central Balkan Postglacial and Early Holocene hunter-gatherers is highlighted as a major obstacle to fully understanding cultural transformations, including the Neolithic transition, in this region. IZVLEČEK - V luči sodobnih arheoloških raziskav smo ponovno preučili kontakt med lovci in nabiralci ter poljedelci na območju Železnih vrat in socialno dinamiko, populacijske premike ter interakcije majhnih družb. Predlagamo, da je med lovci in nabiralci ter poljedelci na območju Železnih vrat v sredini sedmega tisočletja calBC obstajala popolna, nesovražna interakcija, ki ji je sledila kapsula-cija lovcev in nabiralcev na koncu sedmega tisočletja calBC. Poudarili smo, da je glavna ovira pripo-polnemu razumevanju kulturnih transformacij, tudi neolitske tranzicije v tej regiji, pomanjkanje arheoloških zapisov o centralno balkanskih post glacialnih in zgodnje holocenskih lovcih in nabiralcih. KEY WORDS - Balkans; Mesolithic; Neolithic; Lepenski Vir; hunter-gatherer/farmer; interaction; migration; landscape learning Introduction The idea of the potential contact between hunter-gatherers and early food producers during the 7th and early 6th millennium calBC emerged because of the contemporaneity of the Central Balkan Early Neolithic sites with the Iron Gates Mesolithic, along with the occurrence of items and features traditionally related to the 'Neolithic package'1 in Mesolithic contexts (Garasanin and Radovanovic 2001; Jova-novic 1972; Kaczanowska and Kozlowski 2003; Pdunescu 1987; Radovanovic 1996c; Voytek and Tringham 1989). Apart from the Danube Iron Gates Gorges, the existing archaeological record does not imply any straight- forward evidence of contact between hunter-gatherers and early food producers elsewhere in this region. A few sites in the Morava valley, all of them Early Neolithic, may only indicate the possibility of such contact, since the time of their occupation overlaps with the time of the Late Mesolithic and Early Neolithic in the not so distant Danube Gorges. On these grounds, a patchy distribution of rare 'last hunter-gatherers' who co-existed with regional Early Neolithic groups has been proposed (Chapman 1989; Radovanovic 1996c; Tringham 2000; Voytek and Tringham 1989). Confirmed contact of the Iron Gates Mesolithic with the Early Neolithic, based on the presence of various material culture elements assumed 1 In the Balkans, the classic 'Neolithic package' items and features, although marked by important regional variability, may include all or only some of the following: monochrome and/or painted pottery, fired clay objects, rectangular structures constructed from wattle-and-daub, macro-blade chipped stone industries, polished stone objects and grinding stones, domesticated plants and animals (sheep, goat, cattle, pig, wheat, barley, lentils, peas), intramural human burials in contracted position, etc. 107 Ivana Radovanovic to be a part of the 'Neolithic package', goes back at least to 6300 cal BC. It is unlikely that the demographics of the Central Balkans were marked at that time by a proportion of food-producing groups so large as to lead to the encapsulation of the remaining hunter-gatherers. The situation may more accurately be described as a mosaic of diverse hunter-gatherer and early food producing groups having settled different niches, or even sharing them to a certain extent. The early food producers were more probably surrounded by the hunter-gatherers at that time, than vice-versa. The beginning of this contact -preceding 6300 calBC - could be imagined with small 'pioneer' Neolithic groups who had entered this area, but were not able to begin pursuing their established mode of production, based on domesticated plant and animal exploitation, without co-operation with local hunter-gatherers (for a variety of reasons discussed below). This possibility cannot be ruled out only because the diagnostic 'Neolithic package' elements preceding 6300 calBC are absent from Iron Gates Mesolithic contexts. It should initially be explored by identifying changes in a number of different aspects of the IGM hunter-gatherers' material culture, and by investigating whether they could be a direct or an indirect result of that contact (see also Radovanovic 2006a; Tringham 2000.44). The encapsulation of hunter-gatherers' may be probable only in the final stages of the Neolithic settlement of the Danube Gorges and elsewhere over several centuries following 5900 calBC, during the Middle Neolithic Starcevo. The goal of this paper is to discuss such contacts and their impact on different groups living in the area at that time. Late Pleistocene and Early Holocene research bias in the Central Balkans Regrettably, we still know very little about prehistoric hunter-gatherers in Central Balkan areas other than the Danube Gorges. Only in the past few years have a more intensive survey and test excavations targeting the Late Pleistocene sites in this region begun to yield very promising results (Mihailovic D. and Mihailovic B. pers. com), providing further evidence that the Central Balkans is not a Palaeolithic/ Mesolithic void, as has been assumed (but see Tringham 2000.32) (Fig. 1). It is quite unlikely that the Late Palaeolithic and Early Mesolithic hunter-gatherers, or their Palaeolithic predecessors, who frequented the Danube Gorges were the only groups present in the region. It is even less likely, since the Balkan Peninsula was an important refugium for the European living world during the Ice Ages (Kozlow- ski 1999, Misic 1981; Taberlet and Cheddadi 2002; Tzedakis et al. 2000), with no indication of living conditions worsening to such a degree as to force all hunter-gatherers to abandon the entire region at any time during the Pleistocene or later. Some of the evidence could indeed be missing due to the erosive and accumulative processes responsible for the destruction and deep burial of sediments containing a potential Pleistocene and Early Holocene archaeological record (Dolukhanov 1979; Montet-White 1999). However, recent research in Serbia indicates that such explanations are not applicable to the entire Central and/or Eastern Balkans. Therefore, the scarcity of fully explored geological, palaeontological, and archaeological record from the Late Pleistocene and Early Holocene can be noted as the main cause of the inadequate knowledge of and, hence, questionable interpretations regarding the cultural change and transformations that took place during earlier prehistoric periods in the Central Balkans. No wonder that the scarcity of this record influenced so strongly, for example, some versions of the Neolithic demic diffusion model, which portray a relentless population 'wave' advancing from the Middle East over the Central Balkan 'void', circumventing only the Danube Gorges' coastal areas which were settled by the solitary hunter-gatherers. Why is the Palaeolithic/Mesolithic evidence so scarce? The most important reason is the very low priority that Palaeolithic and Mesolithic explorations had in the archaeology of the Central Balkans (principally Serbia) during most of the 20th century. Prehistoric archaeology in Central and South-East Europe was, and to a great extent still is, practiced within the long tradition of the cultural-historical approach, with a significant penchant for the study of the Neolithic and later prehistoric periods. In contrast to neighbouring areas (Hungary, Romania and, much later, Bosnia and Herzegovina, Montenegro, Bulgaria, Greece, and Albania), the Pleistocene and Early Holocene hunter-gatherer settlements in Serbia were of only peripheral interest for most local scholars. The lack of systematic archaeological surveys and scarcity of regional quaternary studies was a recognized fact, but it did not initiate any substantial revision of the 'mainstream' agenda. The belief that the Central Balkans was devoid of human settlement during the Late Pleistocene and Early Holocene was, albeit illogically, reinforced. No wonder that the results of the survey and rescue excavations on the right banks of the Danube Gorges and downstream areas in the mid 1960s, which brought to light evi- 108 Further notes on Mesolithic-Neolithic contacts in the Iron Gates Region and the Central Balkans Fig. 1. Balkan Peninsula with locations of Mesolithic (■) and Early Neolithic sites (•o) (after Tringham 2000). dence of Early and Late Mesolithic camp sites, came as a complete surprise. It is true that the Childean perception of the Balkans as a 'bridge' and/or a 'buffer-zone' between the Near East and Europe influenced the research goals of scholars in both regions, in the past and today (Kot-sakis 2003.217; Tringham 2000.19-56). A significant emphasis was on topics such as the origins of food production, metallurgy, social complexity, and the ensuing processes of their diffusion over the Balkans through population movements, acculturation and exchange, believed to be directly reflected in the spatial and temporal variability of material culture (especially pottery). The study of hunter-gatherers and its potential in the Central and Southern Balkans our topic. While the distribution and density of Central Balkan Mesolithic settlements is still largely unknown, the Greek record shows an uneven geographical distribution, with hunter-gatherer sites in the Epirus, Argo-lid, and on the coasts. Other parts of the country, according to the results of extensive survey, were virtually uninhabited between 13 000 BP and the beginning of the Holocene (Runnels 2003.128). Kotsakis (2001.66; 2003.218), however, does not see this hiatus in occupation as a demographic reality, but rather as another preconception caused by insufficient research (especially evident after the discovery of the Mesolithic in the Theopetra cave in NW Thessaly), coupled with the archaeological invisibility of the sites situated on the now submerged coasts, or in locations buried under alluvium. Perles (2003.103) concurs with Runnels that Greece was extensively surveyed, arguing that it was "sparsely populated during the Palaeolithic and Mesolithic", with the additional setback of the low visibility of Meso-lithic open air sites (in contrast to caves) which were occupied for brief periods of time, thus leaving no substantial material record. She supposes that "if a local dynamic towards more complex and more sedentary societies had taken place, the settlements would have become all the more important and ar-chaeologically visible...exemplified not only by the Near and Middle East with the Natufian and Querme-zian settlements, but also, for instance the Iron Gates Mesolithic or Erteb0lle complex." Perles' note on the subject of hunter-gatherers' shift to greater complexity and/or sedentism driven by 'local dynamics' may be a good opportunity to clarify the term 'hunter-gatherers', either simple, complex or sedentary. Similarly to the Central Balkans, the Palaeolithic and Mesolithic were understudied in Greece in comparison to other parts of Europe. This situation began to change in the 1970s, and Palaeolithic-Mesolithic research has steadily intensified ever since (for recent reviews see Bailey et al. 1999; Galanidou and Perles 2003). However, some questions remained open, particularly in regard to the Post-glacial and Early Holocene human occupation that is of interest for In the early ethnographic literature, hunter-gatherer groups were portrayed as self-sufficient, practicing a pure foraging economy, timeless and stuck in a developmental cul-de-sac. They were marked by "...little personal property and an egalitarian social system; sporadic gathering of the bands, and much mobility of individuals between bands; fluid organization involving no territorial rights; no food storage and no group strongly attached to a parti- 109 Ivana Radovanovic cular area..." (Rowley-Conwy 2001.40). Deviations from this description such as territoriality, trade, social hierarchy, restricted mobility and/or sedentism, and other traits associated with greater complexity, were seen not as genuine behaviours, but as by-products of recent acculturation (Bird-David 1995.17; Layton 2001.293). However, anthropological understanding of the term has been redefined over the past five decades, based both on the observations of hunter-gatherer variability in the modern ethnographic and ethno-histori-cal record, and a diversity of analytical approaches marked by emphasis on one or another aspect of hunter-gatherer existence: economy, behavioural ecology, technology, society, or ideology. A variety of more refined classifications of hunter-gatherers resulted from this work, such as Binford's foragers or collectors, groups with residential or logistic mobility, or Woodburn's groups with immediate- or delayed-return. In terms of social organization they were commonly described as egalitarian and 'simple' or non-egalitarian and 'complex' - (for comprehensive reviews and discussions see papers in Ingold, Riches and Woodburn 1995; Panter-Brick, Layton and Rowley-Conwy 2001). These studies had a different impact on archaeologists and anthropologists, caused, among other things, by the different time-scale of their research. Socio-cultural anthropologists' synch-ronic approach led to a greater awareness of the hunter-gatherers' variability, which encompasses numerous culturally specific economic, technological, social, and ideological responses to local environmental and demographic conditions. The archaeologists' diachronic approach leaned towards progressivist assumptions about hunter-gatherers: that there is a trend from 'simple' to 'complex' groups, that a greater social complexity of hunter-gatherers automatically implies that it had to emerge from a prior simple form, such as the 'Original Affluent Society' described by Sahlins (1972), that a change toward complexity occurs slowly, leads to agriculture as its logical outcome, and that such change is irreversible. Yet, based both on the analyses of ethnographic and archaeological record, each of these assumptions was shown to be incorrect (Rowley-Conwy 2001.44-52; 2004.86). The above noted differences in approaches are certainly simplified, since not all archaeologists are progressivist, and those who are would not subscribe to all these common assumptions. In relation to my topic here, they may help understand the roots of a major disagreement among scholars about the relationship (or a lack of it) between the Iron Gates Mesolithic and Early Neolithic of the Central Balkans. The main split between archaeologists interpreting the same evidence from the Danube Gorges occurred along the line which divides (often implicit) progressivist approaches from their alternatives, which were more concerned with hunter-gatherer responses to the local environmental and social conditions and their historical trajectories (for the history of research in the Danube Gorges area since the 1960s and the effects of these approaches on interpretation, see Radovanovic 1996a). Having argued for a non-progressivist, 'local dynamics' approach, Rowley-Conwy classifies the ethno-graphically observed varieties of hunter-gatherer groups into four types (2001.42): "© the OAS [Sahlins' "Original Affluent Society" type]: groups with little or no logistic movement of resources or food storage, found mostly in tropical regions (e.g. the Aborigines); some occur in higher latitude areas, where resources are available throughout the year and people can move from one resource to the next, exploiting them in sequence without the need for much storage; © logistic groups that do not defend territories, such as most Inuit; © logistic groups that do defend territories - many of Woodburn's delayed return groups; © sedentary groups who invariably defend territories and store resources, forming a continuation of type 3." These types do not develop from one another following a path beginning with type 1 (i.e., 'simple', egalitarian, OAS, foragers, residentially mobile, immediate-return groups) and ending with type 4. All but type 1 can be defined as complex (i.e., non-egalitarian, collectors, logistically mobile or sedentary, de-layed-return groups). Further discussion on type 1 will show that labelling it as 'simple' is yet again questionable. In the complex, delayed-return small-scale societies (pastoral, agricultural and hunter-gatherer), "the binding commitments and dependencies are most often those of kinship and affinity: we may find lineages, clans and other kinship groups (...) marriage alliances between groups (...) and other sorts of formal contractual bonds to which people are committed" (Woodburn 1995.34). In contrast to these, the social organization of groups with immediate-return systems (Rowley-Conwy's type 1) are marked by "flexible social groupings, often no Further notes on Mesolithic-Neolithic contacts in the Iron Gates Region and the Central Balkans changing their composition, individuals that have a choice whom they associate with in residence, in the food quest, in trade and exchange and in ritual contexts; people are not dependent on specific other people, whether relationship of kinship or other relationships, stress sharing and mutuality, but do not involve long-term binding commitments of the sort that characterize delayed-return systems; distinctions - other than those between sexes - of wealth, power and status are systematically eliminated" (Woodburn 1995.34). One among many other examples is the south Indian Nayaka's egalitarian hunter-gatherers' view of kinship, which "was primarily made by recurring social actions of sharing and relating with, not by blood or by descent, not by biology or by myth or genealogy", also a person is sensed as one "with whom we share with" (Bird-David 1999.73). The systematic elimination or discouraging of socially unacceptable behaviours in egalitarian hunter-gatherer groups implies a collective consensus, but it also implies social control and pressure to maintain it; but who is in control and where does the pressure come from? Since egalitarian groups "place enormous emphasis on creating and maintaining communal consensus", this often sparks "a kind of equally elaborate reaction formation" of "the extreme forms of symbolic violence"2 (Graeber 2004.25 and also Clastres 1997). The consensus is thus maintained by re-affirming internalized cultural tradition through various aspects of symbolic conflict (Chamberlain 2006.42). The qualification of theses societies as 'simple' does not make much sense, knowing that such symbolic means of control and pressure act in order to uphold the egalitarian system. Even if the symbolic means are 'imaginary' from the etic standpoint, they are not less real and powerful in the emic view. Along with various types of non-egalitarian hunter-gatherer societies, and "from the perspective of the flexibility, mobility and social equality", egalitarian hunter-gatherer society "may be the most remarkable and specialized social form that humans have ever evolved. It has no claim to be the original human condition" (Rowley-Conwy 2001.65). Furthermore, ethnographically known egalitarian hunter-gatherers were not found in situations of 'pristine isolation', but in interaction with other groups (including ethnographers), with whom they co-operate through relationships of symbiosis, or dependence and subordination (Layton 2001.299302, 306; Pennigton 2001.178; Woodburn 1995. 35). The ethnographic record shows that many of these groups were versatile, switching between foraging and horticulturalist or herding modes of production to suit current conditions (Layton 2001.303). These oscillations between the 'genuine' simple hunter-gatherer mode and more complex ones underline the significant role of the local environmental and social dynamics that perpetuated them. The ethnographic record also shows that egalitarian groups are not pre-existing cultural entities, but special alliances of individuals created in opposition to the internal social dynamics of their 'parental' group and/or to the external pressure of neighbours. This is why they are marked by great fluidity, establishing their 'kinship', in Bird-David's words "not by blood or by descent, not by biology or by myth or genealogy" (l.c.). Such observations are important for archaeologists, especially when they study prehistoric hunter-gatherers' interaction with other groups, either hunter-gatherers, food producers or both. In this respect I agree with Perles' comment above about the importance of local dynamics in the formation of prehistoric hunter-gatherer settlement patterns which directly determines the visibility of the archaeological record. The assumed low visibility of Mesolithic open-air sites in Greece may indeed be the consequence of greater hunter-gatherer mobility (type 1) at that time. Previous discussion also points to a fact that most of the ethnographically known egalitarian groups (i.e., residentially mobile or immediate-return groups) were, at the time anthropologists studied them, surrounded or encapsulated by other small- or large scale societies with whom they may have co-operated. The high mobility (and egali-tarianism) of the Greek Mesolithic groups could therefore have been a result of the interaction with the neighbouring, complex (logistic) hunter-gatherer groups, but the settlements of such logistic groups have yet to be found (along the now submerged coasts or deep under the alluvium, according to Kot-sakis). We have also seen that egalitarian groups could be formed through avoidance of co-operation, 2 Drawing these ideas about symbolic violence, which is reflected in these societies' cosmologies, myths and rituals, from P. Clastres, Graeber continues "...there is a striking contrast between the cosmological content, which is nothing if not tumultuous, and social process, which is all about mediation, arriving at consensus. None of these societies are entirely egalitarian: there are always certain key forms of dominance, at least of men over women, elders over juniors. (...) It is hardly a coincidence that when larger, more systematically violent forms of domination do emerge, they draw on precisely these idioms of age and gender to justify themselves." Ivana Radovanovic provided that the resources they foraged were available all-year round and distributed in niches different from those used by logistic, delay-return groups. In both cases, egalitarian, consensus based groups are created in response and opposition to surrounding groups. They cannot emerge and exist without 'the other'. Woodburn (1995.63) states that "oppositional egalitarian solidarity" may have been repeatedly "invented and re-invented" where "economic circumstances were appropriate" without the need to be triggered by outside pressure. One can also argue that the 'invention' of oppositional egalitarian solidarity may be a response to internal social pressure: social tensions growing inside the parental de-layed-return group (which then becomes 'the other'). The low archaeological visibility of highly mobile hunter-gatherer groups in the Mesolithic in Greece may apply to the period when farming communities were established and attained greater population densities. Some local hunter-gatherer groups (egalitarian or otherwise) were then assimilated, while others could have remained encapsulated for some time, leaving a 'simple' mobile hunter-gatherer signature in the archaeological record. The above discussion on hunter-gatherer variability based on the ethnographic record was interspersed with my comments on recent research in Greece. They served as a 'proxy' to better understand the circumstances of the early to mid-Holocene hunter-gatherer research in the Central Balkans and its potential. Apart from geographical proximity (although not a geographical resemblance), such an alternative was also chosen because of the historical similarities in the mainstream research agendas in both regions which resulted in a considerable dearth of studies of the prehistoric hunter-gatherer record. It not only delayed research of hunter-gatherer variability in this part of the world, but also impeded better understanding of the 'Neolithisation process' which for a long time was, and still is, the main focus of the regional archaeological explorations. This research was heavily biased toward only one side of the 'Neo-lithisation' coin: that of established food producing groups. This process cannot be known without a much better grasp of the local hunter-gatherers' way of life, settlement patterns, ways in which they interacted with other groups, long- and short-distance exchange networks and routes and, in relation to these, the effects of long- and short- distance (small or large scale) population movements; and last but not least, the effects of changing environmental conditions. A brief reminder of the solitary Late Post-glacial and Holocene hunter-gatherer archaeological evidence until the time of contact with early food producers from the Central Balkans, i.e., the Danube Gorges now follows. Late Post-glacial and Early-Mid Holocene in the Danube Gorges The process by which settlement intensified in the Late Post-glacial and Early Holocene in the Danube Gorges is well documented, including the ongoing process of settlement and reinforcement of distinct local cultural identity markers observed in the standards of material culture production (Radovanovic 1996b) (Fig. 2). The Iron Gates region witnessed extensive settlement in this period at the Climente II cave, the rock shelter at Cuina Turcului, and at the open air sites of Padina (layer A1) and the earliest occupation at Vlasac (Koziowski 1999; Radovanovic 1981; 1996a). While the caves and rock-shelter sites in the Iron Gates area of this period are marked by activities such as the specialized hunting of ibex (Cuina Turcului) or red deer and wild boar (Climente II), the open air camps at Padina A, Vlasac and probably a number of other sites, specialized in fishing. These sites were not all-year-round settlements, but locations belonging to a broader network of sites used by local hunter-gatherer groups. The full territorial extent and complexity of this network is still unknown. The local hunter-gatherers' inclination of establishing and frequenting fishing camps along the Danube, both in the Iron Gates Gorges and downstream, continued to intensify in the Early Holocene through inter-group competition, sometimes resulting in hostile interactions (Lourandos 1995.150; Radovanovic 2006b; Roksandic et al. 2006). These camps were regularly revisited, with the material culture record reflecting the presence of logistic, territorial and complex hunter-gatherer groups who established permanent structures and formal disposal areas at Padi-na, Vlasac, Proto-Lepenski Vir, Icoana, Hajducka Vodenica, Schela Cladovei, Kula (Radovanovic 1996a) (Figs. 3 and 4). The growing significance of aquatic resources in the subsistence of these communities was confirmed both by the predominance of fish in the faunal remains and palaeodietary analyses revealing a strong aquatic signature (Bonsall et al. 1997). A trend toward greater social complexity, permanence of settlements and the territoriality of coastal hunter-gatherers whose subsistence was based on aquatic resources (either from the sea, lakes or large 112 Further notes on Mesolithic-Neolithic contacts in the Iron Gates Region and the Central Balkans Fig. 2. Mesolithic sites in the Iron Gates Gorges (after Radovanovic 1996a;. rivers) is a well explored phenomenon in archaeology and ethnography (for example, see Palsson 1995.194 ff on the strong correlation between dependence on coastal resources and permanence of settlement). However, there was a major shift from aquatic resources to mixed a terrestrial diet around the mid-7th millennium calBC (Bonsall et al. 1997). Several other lines of evidence also mark a considerable change in the Iron Gates Mesolithic community's way of life at that time. Studies of the material culture from the entire region imply a restriction of the size of territory settled by Iron Gates Mesolithic hunter-gatherers in this period, and the abandonment of the entire left bank and parts of the right bank of the Danube with downstream areas (for the abandonment of sites implied by stratigraphic gaps and discontinuities in traditional technologies see: Antono-vic 2006; Radovanovic 1996a; 1996c). This assumption was supported by Bonsall and his collaborators' (2000) discussion on the lack of continuity in 14C dates for the period between ca 6300-5900 calBC at Vlasac, Icoana, Ostrovul Banului, Ostrovul Corbului, and Schela Cladovei, and the later re-occupation of these locations at 5900 cal BC. Post 6300 calBC, massive site abandonment coincides with the establishment of a new series of permanent structures in only two (explored) settlements in the Upper Gorges: Padina B and Lepenski Vir I-II. Traditional forms of settlement organization, architectural elements and burial practice were modified, and new material, such as pottery and other artefacts of local Early Neolithic provenance was incorporated (Garasanin and Radovanovic 2001; Radovanovic 1996c; 2000; 2006a). There is evidence confirming continuity at the Lepenski Vir settlement between 6300 and 5900 calBC (Bonsall et al. 2004), and a conti- nuity of the settlement at Padina has also been proposed (Boric and Miracle 2004). The presence of new material culture elements has led archaeologists to assume the co-existence of Lepenski Vir and Padina communities with the regional Early Neolithic groups. Among the main elements indicating direct contact with Early Neolithic groups are diagnostic raw materials and technologies (see also different arguments, but the same general idea, in Boric 1999; Jovanovic 1987; Kaczanowska and Koztowski 2003; Kozlowski 1982; Koztowski and Koztowski 1984; Pdunescu 1987; Radovanovic 1996a; Voytek and Tringham 1989). The question of the presence of pottery between 6300 calBC and 5700 calBC in the Iron Gates Mesolithic in the Upper Gorges has been explored (Garasanin and Radovanovic 2001; Radovanovic 1996a) in view of the stratigraphically secure evidence from Lepenski Vir phases LV I/2-3 and Padina B/I-III. In order to clarify which Neolithic group came into contact with the Mesolithic community at Lepenski Vir and Padina, this evidence was correlated with the Early Neolithic of the Central Balkans (see Tab. 2 in Garasanin and Radovanovic 2001). A conclusion very similar to Srejovic's (1966b) first interpretation of the Lepenski Vir stratigraphy was reached, that is: Lepenski Vir I represents phase I of the Starcevo culture in terms of pottery presence, while Lepenski Vir IIIa and IIIb correspond to Star- Fig. 3. Sculptures from Lepenski Vir structures (Institute of Archaeology, Belgrade). 113 Ivana Radovanovic čevo IIa and Starčevo lib respectively. Effectively, 'Proto-Starčevo' and Starčevo I would represent one and the same initial phase in the Starčevo cultural sequence, strongly marked by early elements of the Balkan-Anatolian complex of the Early Neolithic (Fig. 5). The Danube Gorges will be reoccupied at a later date, after 5900 calBC. These settlements (apart from Pa-dina and Lepenski Vir, where the Mesolithic 'cultural identity' markers still endured) were built according to 'classic' Neolithic standards: irregular dugout dwellings and/or above ground huts, with rectangular ground-plans furnished with circular hearth constructions, such as at Razvrata II, Ostrovul Mare km. 873, Ostrovul Corbului II/hor.VII, Hajdučka Vodenica II, Donje Butorke, Ajmana, Pesak-Vajuga, Velesnica, Usee kameničkog potoka, Knjepiste, and Alibeg at the entrance of the Danube to the upper gorges (Radova-novic 1996c.43-44). Bonsall et al. (2000) hypothesized that the abandonment of a large number of the Iron Gates Mesolithic sites in the period 6300-5900 cal BC could have been triggered by the global climatic oscillation at 8250-7900 BP (cca 6300-5950 calBC). This event was marked by cooler and wetter conditions, and may have resulted in extensive periodical flooding of the Danube banks. In their view, the exception would be the settlement of Lepenski Vir, which the Iron Gates Mesolithic community probably regarded as a sacred site, and therefore chose not to abandon. The duration of this climatic oscillation corresponds to the construction of the Lepenski Vir I structures, with floors made of a heavy-duty mixture of limestone and sand unique in the whole Iron Gates area (Fig. 6). These sturdy floors have been interpreted as protection against the structures being washed away by flooding (see also Chapman 2000.195). Borie and Miracle (2004) opposed this interpretation because of the lack of evidence of sediments that may correspond to floods. The palaeo-climatological record on the effects of the '8200 BP cold event' in South-Eastern Europe is still inconclusive. In contrast to North-western and Central Europe where a highresolution record about this event was assembled, its magnitude and effects farther east in Eurasia are unknown (Davis et al. 2003; Morrill and Jacobsen 2005; Veski, Seppa, and Ojala 2004) Although the abandonment of the Iron Gates Mesolithic sites cannot be explained only in terms of climatic deterioration, some floods and their impact on local groups cannot be excluded. Srejovic (1966a) observed 'a Fig. 4. Early Mesolithic burial, from Proto-Lepenski Vir (Institute of Archaeology, Belgrade). thin layer of brown loessic sand' at places between the LV I and LV II settlements, and supposed that the site could have been abandoned for some time. In my view, the lowermost parts of this site might have been abandoned: according to my 1996 phasing of LV I settlements, the latest phase of Lepenski Vir I (LV I/3, corresponding roughly to Srejovic's phases LV Id-e) consists of somewhat overcrowded rows of houses located on a steep slope in the rear of the settlement (Radovanovic 1996a.Figs. 3.17, 322, 3.23 and especially 3 36). It is therefore likely that the retreat of the entire settlement higher up the slope might have been related to an increased danger of flooding at the lower elevations. Therefore the structures in these elevated parts of the site could have avoided periodical flooding. A similar trend of 'retreat up the slope' of the chronologically latest houses has also been observed at Padina, another Mesolithic site that continued to be used over a considerable time during the VI millennium calBC (Radovanovic 1996a.Fig. 3.5). Contacts and transitions The internal relationships within a small-scale society that constitute their social organization are often separated in anthropological literature (for analytical purposes) from external relationships with neighbours, traders, newcomers, etc. This external relationship is usually termed 'contact' (for a critique of this analytical division see Bird-David 1995.17), 'coexistence' and 'interaction' that ranges from the sym- 114 Further notes on Mesolithic-Neolithic contacts in the Iron Gates Region and the Central Balkans Fig. 5.

The following discussion focuses on contact between hunter-gatherers and farmers. Although it is another analytical division that may be criticized (we only need to remember the above-noted oscillations in the production mode of 'egalitarian' small-scale societies), Rowley-Conwy (2004.97) stated that the hunter-gatherer:farmer dichotomy is analytically and empirically valid. He compared three phases (availability, substitution, consolidation) of the model of transition to agriculture (Zvelebil and Rowley-Conwy 1986) to the results of Hunn and Williams' (1982) study of the economic practices of 200 ethnographi-cally known small-scale societies. Zvelebil and Row-ley-Conwy's availability phase predicts that a small- Fig. 6. Lepenski Vir I structures (Institute of Archaeology, Belgrade). scale society depends on less than 5% of agricultural products in their diet; the substitution phase would include 5%-50%, and the consolidation phase more than 50%. Hunn and Williams' study has shown that in ethnographically known small-scale societies, agricultural products contribute either less than 5% to the diet (these are hunter-gatherers, corresponding to Zvelebil and Rowley-Conwy's availability phase) or more than 45% (agriculturalists, corresponding to the consolidation phase). Statistically negligible percentage reflected 5%-50% participation of agricultural products (substitution phase), implying that this phase is unstable and probably of very short duration, and would probably be difficult to detect in archaeological record. According to these data the small-scale societies would consist of either hunter-gatherers or farmers, not likely to linger in the intermediate substitution phase (Rowley-Conwy 2004. 97). This brings us to the topic of current palaeo-die-tary studies in the Iron Gates Mesolithic A new and larger series of radio-carbon measurements of the remaining and still datable archaeological record from the Iron Gates Mesolithic sites has been vital for further clarification of the duration, continuities and actual contemporaneity of particular settlements. The combination of dating human bones with the use of 5-13C and 5-15N dietary analyses has produced a powerful (although not entirely conclusive) tool for the understanding of burial record, deposition processes and habitat in the area (Bonsall et al. 2006). According to the initial study of Bonsall et al. (1997), there was a shift from a considerable intake of aquatic resources to a broad-spectrum diet, with emphasis on terrestrial resources, based upon the values of ii5 Ivana Radovanovic 513C and 515N in the collagen extracted from human bones from the sites of Lepenski Vir, Vlasac and Schela Cladovei. Another explanation was offered, relying upon Schulting's model (1998), emphasizing a shift from a marine/aquatic to a mixed diet, with a considerable intake of freshwater fish. It was pointed out (Radovanovic 2000) that regardless of the differences between these two models, they both imply that a significant dietary change took place in the Iron Gates Gorges after the mid-VII millennium cal BC and, for the convenience, the diets were marked as 'Early' (before the dietary shift at the mid-VII millennium cal BC) and 'Late' (after the dietary shift). In further discussion on the stable isotopes and food resources in the Iron Gates area, Bonsall et al. (2000) rejected the suggestion that anadromous fish (which may contribute to the "marine aquatic" signature) could be a source of the high 515N values in some Mesolithic skeletons - which were higher than those expected for a diet based on freshwater fish only -"because there was no corresponding enrichment in 513C values, and because average 515N and 513C for Mesolithic adults in Schela Cladovei (where there is abundant evidence for Mesolithic exploitation of sturgeon) appeared very similar to those of their counterparts at Lepenski Vir and Vlasac where no sturgeon remains were identified..." Part of this argument would be contested by a later report stating that sturgeon remains were identified in the faunal assemblage collected from and/or beneath Lepenski Vir house floors, apparently missed in the course of S. Bokonyi's initial analysis of this material in 1960s (Boric et al. 2004). Nevertheless, this new information does not substantially affect the argument of Bonsall and collaborators, since the Danube Acipen-seridae were in fact freshwater fish until 5600 calBC, when the Black Sea became a marine environment after rejoining the waters of the Mediterranean (Bon-sail et al. 2000; Ryan et al. 1997). On the basis of stable isotope analyses Bonsall and collaborators proposed palaeo-dietary groupings of the skeletal remains from Lepenski Vir, Vlasac and Schela Cladovei into two periods - Mesolithic and Neolithic - the former marked by high 515N values, and the latter with these values depleted. These data were then imposed on Srejovic's (1969; 1972) phasing of occupation at these two sites. However, after the new AMS dates were correlated to Srejovic' phases LV Ia-d, LV IIIa1-a2 and LV IIIb, they appeared to be inconsistent both with the phasing and the known radiometric measurements of the charcoal samples from Lepenski Vir structures. A problem emerged, since the AMS dates from bone samples seemed to be older than the radio-carbon measurements of charcoal samples from the concurrent contexts. Cook et al. (2001; 2002) succeeded in overcoming this problem, having found that the AMS dates from the bone collagen have to be corrected for a freshwater reservoir effect (FWR), based on the premise that "human diet may have included material from a reservoir that differed in 14C specific activity from the contemporary atmosphere". The AMS dates of individual human bones were corrected for the corresponding FWR, and this procedure resulted in a series of radio-carbon dates that were, at this time, more satisfactorily correlated with known 14C dates obtained from charcoal samples at Lepenski Vir and other sites. Nevertheless, the problems of the inconsistency of human burial dates with those of the house phases at Lepenski Vir remained (Bonsall et al. 2006; Radovanovic 2006b) (Fig. 7). Further analyses of the stable isotope signatures from the Iron Gates Mesolithic ensued. Grupe et al. (2003) provided additional information about stable isotope signatures from Lepenski Vir and Vlasac, noting that the "younger human finds at Lepenski Vir are not only morphologically totally different from the older finds, but tend at the same time to have the lowest 515N values". Similarly to Bonsall et al. (2000), their analysis implies a diachronic change in palaeo-dietary habits at this site. Bonsall et al. (2000; 2002) maintain that the "younger" sample has a strong "terrestrial" isotopic profile, based on the increase of 513C in the isotopic signature, which corresponds to cattle rather than to deer. It remained less clear why they refer to this type of signature as the signature of domestic cattle only (see also Grupe et al. 2003). Bonsall et al. (2000) provided two possible scenarios for the palaeo-dietary change in the Iron Gates Mesolithic: either the adoption of a food producing economy, or exchange for agricultural products with neighbouring farmers (see also Tringham 2000; Voytek and Tringham 1989). Other scenarios proposed that a decrease in the importance of fish as a staple food resource was triggered by contact with first farmers (Radovanovic 1996a; 1997), or excluded the possibility of a diet based on agricultural products, since the lack of domesticated faunal remains at Lepenski Vir does not support such a possibility, along with the fact that the Danube Gorges are quite unsuitable for agriculture (Boric et al. 2004). These two scenarios imply that the local hunter-gatherers switched to the mixed broad spectrum diet (based on hunting and fishing) 116 Further notes on Mesolithic-Neolithic contacts in the Iron Gates Region and the Central Balkans Lepenski Vir phases Ranges of FWR corrected and calibrated AMS dates Number of occurrences Proto-Lepenski Vir 9320-9190 BC 8310-8180 BC 2 Lepenski Vir I/i none Lepenski Vir I/2-3 6380-6200 BC 6080-5970 BC 12 Lepenski Vir II Lepenski Vir IIIb 6010-5810 BC 5720-5550 BC 5 Fig. 7.

Archaeologists have never viewed it as just another fishing camp, but as a probable aggregation site that may have witnessed intense ritual activities3 since its Early Mesolithic (Proto-Lepenski Vir) phase, and which continued to play an important social and ritual role in the lives of local communities in later periods, both during and after the above-noted abandonment of sites on the left Danube bank and the Lower Gorges. According to this third scenario, if the structure of faunal remains at Lepenski Vir contradicts the palaeo-dietary signature of the individuals buried at this same site, it is clear that Lepenski Vir could not have been a hunter-gatherer residential site, since it does not reflect the everyday subsistence activities of the group who used it. at the time of contact with the Early Neolithic. I have earlier (Radovanovic 1996a.314; 1997) attempted to explain the contradiction between the faunal record in the post 6300 calBC Lepenski Vir (reflecting the significance of .-selected resources and the ensuing greater mobility of hunter-gatherers) and the perpetuation of settlement's permanency and symbolic displays (in spite of the diminished importance of r-selected resources i.e, fish) in terms of the local Mesolithic population's social and ideological resistance to contact with Early Neolithic groups. I will here add yet another potential scenario that does take into account an intake of domestic food resources (as proposed by Bonsall et al. 2000) by the individuals interred at Lepenski Vir after 6300 calBC. These individuals could in fact have been affiliated to the early farming communities who lived in areas outside the Danube Gorges, at least during the past 10 years of their lives. The settlement of Le-penski Vir is usually, and with very good reason, taken to be quite dissimilar to other sites in the Danube Gorges, because it is the only site with substantial durable structures containing sculptures and other symbolic artefacts, a record of complex burial procedures, a strong demographic bias of burials in favour of males, along with a large number of newborns and infants beneath the trapezoid structure The question, therefore, is not if Mesolithic hunter-gatherers interacted with the Early Neolithic groups, but how were these groups affected by this interaction. Do Lepenski Vir settlements I and II reflect the availability phase (a hunter-gatherer diet, based on the faunal remains and a palaeo-dietary signature interpreted as wild resource intake), or consolidation phase (farmer's diet, based on the pa-laeo-dietary signature interpreted as domestic resource intake) in terms of Zvelebil and Rowley-Conwy's agricultural transition model. Before exploring these scenarios further, let us first revisit briefly the concept of migration, since it has had an important role in archaeological interpretations of the Meso/Neolithic transition in South-east Europe. Migrations and landscape learning Anthony's (1990) comprehensive review of this concept describes the causes for migration in terms of push (economic and/or social tension in the home region) and pull (attraction in the destination region) factors. He distinguishes long and short distance migrations with the likelihood of a long-distance migration to occur "much more rapidly among societies with focal economies, since they were likely to deplete critical resources within a given unit 3 Ritual performances at residential and aggregation camps in the ethnographic record involve visits by supernatural beings who appear through trance and dance, or make their voices heard, for example 'shaking tent ritual' among the Cree, the !Kung 'medicine dance', the Hadza's 'sacred epeme dance, the Batek 'fruit season's singing session' and the Palyan and Pandaram 'spirit possesion'. These ritual performances may be held as frequently as weekly among the !Kung, monthly among the Hadza, and "whenever need arises" among the Pandaram, and they could include up to one third of the community (Bird-David 1999.78). 117 Ivana Radovanovic area more rapidly than societies practising diffuse or broad-spectrum subsistence strategies..." i.e., among farmers, and "given the proper mix of home negatives, destination positives, and low transport cost, focally adapted farmers might be considered more likely to migrate long distances than broad spectrum hunter-gatherers. Local moves would have only subtle effects on material culture, and would therefore be difficult but not impossible." (ibid. 901) Short-distance migration will consist of slow gradual moves and is generally distinctive for hunter-gatherers. The migration process begins with movements of a few people ('scouts'), often along known, previously used routes in long-distance exchanges. Such small groups are goal-oriented, since migration is unlikely if there is no information about the destination region. Scout movements can be rapid (leap-frog migration), reaching quickly and deep into the new lands, and they are archaeologically detectable as 'islands', separated by less desirable (either settled or unsettled) territory. A secondary flow (chain or stream migration) of larger groups will follow, "which is quite different in goal orientation and composition from the initial migrant group" (Anthony 1990.902), moving along the known route and establishing the 'residential' phase of more substantial land use (Runnels 2003.126127). Migrants will move along mega-patches, such as easily traceable geographic features, rivers, linear mountain chains, clear ecological zones, i.e. landscapes more easily internalized into a cognitive map (Kelly 2003.54). This brings us to an explanation of the concept of landscape learning, which describes the consistent process of developing knowledge about a new environment. It is a "social response to situations in which there is both a lack of knowledge of the distribution of natural resources in a region and a lack of access to previously acquired knowledge about that distribution" (Rockman 2003.12), which is precisely the situation that the pioneer colonizers had to confront. Drawing upon Rockman (2003), Meltzer (2003) offers a model that takes the factor of new landscape learning and its speed, curve and mode, as an important part of colonizing success, which may contribute significantly to our understanding of the process of settling in unfamiliar environments. He proposed a basic division: landscape learning with no resident population, and landscape learning with a resident population. Since there was a resident population in the Balkans, I will note only the part of 118 his model regarding the modalities of interaction between the resident population and the colonizers: no interaction; limited or hostile interaction; and full (non-hostile) interaction. In all cases the newcomers would have to learn about the environment from landscape cues and the indigenous population. The mode of learning would have been copying in the case of 'no interaction', and tutorial in cases of 'limited' and 'full interaction'. However, the speed of learning is greatest and the learning curve steepest only in the case of full and non-hostile interaction. Landscape learning is slow, and includes not only building personal experience, but also incorporating those of preceding generations. Its slow rate stands in contrast to the fast pioneer colonization (or rapid directional dispersal) model established for the Early Neolithic colonization of Southeast Europe (Perles 2003; Zvelebil 2001). This model is supported by a number of recent studies of ancient and modern DNA (Bentley, Chikhi, and Price 2003.63; Haak et al. 2005.1017; Richards 2003.159) and the latest series of the Final Mesolithic and Early Neolithic radio-carbon dates from the Central Balkans (Bonsall et al. 2004; Boric and Miracle 2004; Whittle et al. 2002). Kelly (2003.54) explains, when discussing the fast rate of colonization process that ".people are not able to learn landscapes, since learning requires personal experience that is gathered from an early age and that is encoded in folklore that requires some time depth in development" and adds "that this means, coincidentally, that the nature of the adaptation brought with a colonizing population will have a strong influence over the initial choices made." Since the new environment cannot be learned quickly, migrants need to rely upon a more generalized knowledge, choosing to settle areas ecologically and topographically similar to those in their homeland or, in the absence of these, in areas with less than optimal conditions for their traditional mode of production. The colonizers' choice of particular ecological niches is detectable in the archaeological record, since they preferred to settle in the flood plains where they could practice agriculture optimally, in Thessaly, for example, and later in the Pannonian basin (van Andel and Runnels 1995.481). A preference for such niches is reflected in the establishment of long-term settlements. It cannot be explained only in terms of topographical, hydrographical, and ecological conditions and how well they seemed to fit the migrants' expectations. Such choices of niches may also imply an awareness of the fixed inter-group bounda- Further notes on Mesolithic-Neolithic contacts in the Iron Gates Region and the Central Balkans ries separating farmers from the surrounding niches exploited by the local hunter-gatherers. In the Thes-salian Early Neolithic, for example, such boundaries are reflected in a deliberate avoidance of exploitation of the wild resources, local lithic raw materials and use of caves and rock-shelters, which is interpreted as an implication of a possible cultural prohibition (Perles 2001.5; 2003.106; see also Thomas 2003.69). Discussing the faunal record from the Balkan Early Neolithic sites south of the Morava/Vardar watershed and Sredna Gora mountains in Bulgaria, Tringham (2000.25) also notes that wild food resources in the local rich micro- and macro-environment were under-utilized, but she wonders if it was "through ignorance or through resistance to venturing far in space or concept into the unknown." Both scenarios are viable, since the niche separation could initially have been the result of 'non-interaction' or 'limited interaction", or, basically a hostile interaction with local hunter-gatherers. A slow pace of landscape learning is therefore implicated ('a resistance to venturing in space'). The encapsulation of the local hunter-gatherers at a time when a greater population density in the Early Neolithic of Southern Balkans was reached, may have led to the introduction of such 'cultural prohibitions', and this brings to mind similarities with more recent examples of the hunter-gatherer/farmer social interaction from the ethnographic record (Woodburn 1995.37-40)4. However, following Meltzer's model, learning a new landscape may also have been a fairly rapid process, due to a completely non-hostile interaction with the local population. In the case of the Central Balkans and the Iron Gates region, one can easily recognize the archaeological signature of the initial Neolithic as a 'rapid directional dispersal', including the Meso/ Neolithic 'mix' that occurred in the Lepenski Vir settlements. The very first Early Neolithic settlers in the Central Balkans were individuals or smaller groups that actually needed the support of the indigenous hunter-gatherers in order to gain crucial information about a variety of factors such as the local topography, short-term seasonal climatic, hydrographic and ecological fluctuations, long-term changes in the availability of resources and the likelihood of catastrophic events - information that otherwise has to be learned over several generations. As stated at the beginning of this paper, we know almost nothing about these hunter-gatherers outside the Iron Gates region. However, we can see that the archaeological signature of the Early Neolithic settlements in the Central Balkans stands in contrast to those in the South. The settlements are short-term, tactical, and 'opportunistic', and there is no clear 'niche separation' (local lithic raw materials are used along with exotic ones; caves and rock-shelters were utilized; wild game exploitation is practiced), in contrast to the above discussed Thessalian and Bulgarian record (Tringham 2000.25). In the Danube Gorges case, learning about the new landscape may have required learning/rom the resident population and within the framework of the resident population's tradition - understood here as the totality of "the socially and culturally defined normative rules for the transmission of knowledge and practical skill from one generation to another" (Zvelebil 2001.1). The archaeological signature of the Meso-Neolithic contact in the Danube Gorges, for example, implies that encounters with the local Me-solithic population were not marked by conflict, quite in contrast to the local inter-group or inter-personal violence during the Early Mesolithic reported at Vlasac and Schela Cladovei (Boroneanf 1973; Roksandic et al. 2006). Ensuring this support necessitates very close social links with a resident group, including exchange and inter-marriage. Regardless of their knowledge of plant cultivation and stock breeding from their homeland (and in spite of bringing some or all of the 'Neolithic package'), the newcomers could not have been self-sufficient, either economically or socially, for some time in the novel and unfamiliar surroundings (Tringham 2000.49, Zvelebil and Lillie 2000.64-65). In this respect I agree with Tringham (ibid. 47) that the (Mesolithic) "fora- 4 Such cultural prohibitions targeted at the hunter-gatherers are conceivable in the circumstances of their encapsulation. Woodburn (1995.34, 40) notes that "...nomadic hunting and gathering as a way of life does offer so many patterned contrasts to the cherished values of successful farmers that it is readily represented as alien and unintelligible; for farmers, it simply cannot be a 'real' coherent way oflife at all and must be a bastardized form" These cultural prohibitions would justify a farming community's pressure on the hunter-gatherers, which may include some or all the following: "attempts to kill or injure them or to coerce them using violence; to classify them as inferiors and to treat them as such; to seize and entice them (especially their women and children) to work as slaves, servants or clients; to dispossess them of their land or the natural resources of their land; to seize their artefacts, or wild resources they have harvested; to divert them from working to meet their own needs into working to obtain furs, ivory, honey, meat, or other goods required by outsiders; to proselytize them and incorporate them, often in subsidiary roles, into outsider religious and ritual systems." 119 Ivana Radovanovic gers in the Danube Gorges would have been the more dynamic partners in that interaction", because "they had greater access to exchange relations with agriculturalists, along with ceremonial paraphernalia and social complexity that such status might imply." The post-6000 calBC farmers and stock-breeders in the Morava and Middle Danube valley would actually represent a part of the "secondary flow", a further north-westerly move of the south-east European agricultural frontier (van Andel and Runnels 1995; Zvelebil 2001; Zvelebil and Lillie 2000). This possibility has been supported by the recent radio-carbon dating for a number of these settlements, along with the palaeoecological evidence (Whittle et al. 2002; Willis and Bennett 1994). The groups spinning off that population were those that re-occupied the Iron Gates Gorges, establishing classic Starcevo-type settlements in the previously abandoned locations (Vla-sac, Schela Cladovei etc.) and in locations that were still in use, enduring since the mid 7th millennium calBC, at Lepenski Vir and Padina. Conclusion The Mesolithic-Neolithic contact - preceding 6300 calBC - in the Danube Gorges was initiated by small 'pioneer' Neolithic groups. They were not self-sufficient economically and socially upon their arrival, and in order to subsist, had to co-operate with the resident population within the local framework of cultural traditions. Their 'signature' in the Iron gates Mesolithic include some elements of the Early Neolithic 'package', but may also be seen in some other aspects of the Late Mesolithic archaeological record (reflected in modifications of architectural standards and burial procedures). Based on the Early Neolithic record in the Central Balkans, a similar scenario of non-hostile interaction with local population may be expected. During this still unclear process of the early interaction between hunter-gatherers and farmers or stock-breeders around 6300 calBC, the Iron Gates Mesolithic sites were abandoned, except for Lepenski Vir and Padina, either as a result of climatic deterioration, increasing colonizers' pressure, or both. These factors did not allow Mesolithic hunter-gatherers to continue the intensive exploitation of aquatic resources. Since the intensification of aquatic resources and more permanent settlement among coastal hunter-gatherer groups is primarily triggered by inter-group competition, the abandonment of almost all fishing camps implies that this kind of competition ceased. The palaeo-dietary signature of this population confirms that aquatic sources ceased to be a staple food resource. These Late Mesolithic hunter-gatherers switched to a more mobile way of life, implied by the .-selected species in the faunal record. However, they continued to use the only two remaining locations - Lepenski Vir and Padina - probably as seasonal fishing camps and aggregation sites. On the one hand, the interaction with Neolithic groups was non-hostile and fully cooperative. On the other, the perpetuation of these locations' use and symbolic displays in material culture probably reflect the above described 'symbolic conflict', especially at Lepenski Vir. In spite of the diminished importance of r-selected species (i.e., fish), this situation is interpreted in terms of the local Mesolithic population's ideological, but not economic and social, resistance to contact with the Early Neolithic groups. According to another scenario, the mixed terrestrial signature in the palaeo-dietary record of the Lepenski Vir population is interpreted in terms of subsistence based on domestic food resources (but then, this population can no longer be a hunter-gatherer population). The end of the cold and wet climatic oscillation at 5900 calBC corresponds to a more substantial Neolithic settlement of the Central Balkans, including the Iron Gates and neighbouring areas, as indicated by the increasing number of recorded Middle Neolithic archaeological sites. This secondary flow would correspond to larger farming population moving and settling in the Central Balkans, establishing longer-term settlements and more extensive land-use in the Morava and the middle Danube basin. The Danube Gorges sites were re-occupied, but this time by Neolithic groups displaying a full range of the 'Neolithic package' elements. The increase in Neolithic population density (which included the second wave of 'colonizers', descendants of early colonizers and local residents, and the assimilated groups of local hunter-gatherers) outside of the Danube Gorges, probably triggered the encapsulation of the remaining hunter-gatherers in the Upper Gorge. They continued for some time to re-affirm their cultural traditions by maintaining and revisiting the long-established Lepenski Vir and Padina aggregation camps, until in the mid-6th millennium when they were finally abandoned - but the surrounding Middle Neolithic settlements in the Danube Gorges were soon to be abandoned too. In their discussion on the Iron Gates Mesolithic, Fiedel and Anthony (2003) captured very well a probable reason for such development: "...the Neolithic farmers were less concerned with securing a good local fishing place than with winning control of this nexus of indigenous social 120 Further notes on Mesolithic-Neolithic contacts in the Iron Gates Region and the Central Balkans and ideological resistance. Once they accomplished their goal, they had little further interest in this agriculturally marginal area". Recent studies in the Meso/Neolithic transition based on, for example, genetic models (Barbujani and Chikhi 2006), population dynamics (Davison et al. 2006), and radio-carbon data (Gkiasta et al. 2003. 48) were not discussed here at great length. They all emphasize the 'overall process' and 'continent-wide patterns' which could not, so far, contribute substantially to a topic that attempted to explore local social (and demographic) dynamics, which we have seen to be of the outmost importance in the understanding of any kind of 'transition'.

In the last few years it has become clear that at least three different types of transitions can be distinguished in the Eastern Plain (Alfold) region: one in the Jdszsdg area with authentic Mesolithic sites, one in the northern, one in the northeastern fringes of the Koros distribution area, and a further one in the southern part of the Danube-Tisza Interfluve where the impact of the formative Vinča culture must also be reckoned with. All regions differ from each other, concerning the contacts with Mesolithic population and the phases of neolithisation. Regarding Transdanubia, the picture becomes even more complex. The transition to the Neolithic obviously differed in each region: in the Drava valley where the Starčevo presence was very intensive, in the marshland around Lake Balaton, in the Rdba valley lying close to the Alpine foreland, in the northern Transdanubian Danube valley and in the Little Hungarian Plain. Rejecting the simplifying model the assumption of a mosaic-like series of variations in the neolithisation process is offered. The process of Neolithisation is thus is far from being unified in the various regions. This short study tries to seek different models of neolithisation behind the differences. IZVLEČEK - Do nedavnega so Karpatski bazen smatrali za enotno področje neolitizacije. V zadnjih nekaj letih pa je postalo jasno, da lahko na področju Vzhodne ravnice (Alfold) ločimo vsaj tri različne tipe tranzicije: prvega na področju Jdszsdg, s prvotnimi mezolitskimi najdišči, drugega na severnem in tretjega na severovzhodnem obrobju področja Koros, še enega pa na južnem delu Donavsko tiškega porečja, kjer je potrebno računati tudi z vplivom kulture Vinča. Regije se v procesu neoliti-zacije med seboj razlikujejo tudi v odnosih med mezolitskimi in neolitskimi populacijami. V Trans-danubiji je ta podoba še bolj kompleksna. Tu je neolitizacije v vsaki regiji potekala drugače: v Dravski dolini, kjer je bila močno navzoča kultura Starčevo, na močvirnatem področju okrog Balatonske-ga jezera, v dolini Rabe, ki leži blizu alpskega predgorja, v severni Transdanubijski donavski dolini in na Mali madžarski ravnini. V članku zavrnemo poenostavljen model neolitizacije in ponudimo domnevo o mozaični seriji regionalnih procesov neolitizacije. KEY WORDS - Carpathian Basin; Neolithic transition; Koros, Starčevo; early and developed LBKgroups The Pre-Neolithic period in the Great Hungarian Plain (Alfold) In Hungary, there is only one region where a settlement niche, a series of authentic Mesolithic sites, has been found, researched and proceeded. This is the Jaszsag area, east of the Danube (Fig. 1) Here, two phases were distinguished by the excavator, Kertesz: besides the older Mesolithic Jaszbereny phase, a set- tlement of the latest period was also identified at Jasztelek. (Kertesz 1994a; 1994b). The environmental and historical reconstruction of this phase has given basic new information about the phase immediately preceding the Neolithic (Kertesz-Sümegi 1999; Sümegi 2003). 125 Eszter Banffy The north-eastern part of the Alfold (Fig. 2) shows a fairly different picture from the mid-northern fringes, at least in the present state of research. The catchments of the rivers Berettyo, Sebes and Fekete Koros form a complex, articulated landscape frequently dotted with marshes and swamps. Although stone artifacts of the Late Mesolithic - preceding the times of permanent settlements - are known from as far as Western Romania, no archaeological evidence of any settlements has been found. The palaeo-environmental analysis, however, was able to show up some evidence for pre-Neolithic clearing and forest burning activity from around 8400 cal BC, paths in the woodland e.g. in the Batorliget marsh region as well as near the village of Csaroda in a marshy area, the 'Nyires lap' (Sumegi 2003.21-22, Fig. 1; Sumegi-Gulyds 2004. Ch. 3.8: Pollen and charcoal analysis). Around 8400 calBC Tilia lost its dominace and Quercus became more typical (Willis et al. 1995), indicating closed forestation due to a milder climate with more precipitation. Dates for the mollusk fauna allow similar inferences (Sumegi 2003.21). Given space for sunlight, the growth of berries and especially hazelnut in the bushy-shrubby undergrowth were enhanced. Favorable changes in the landscape were further intensified by small-scale bush clearing, as findings from several European localities have indicated (Gronenborn 1999; Zvelebil 1986; 2000). Pre-Neolithic "Tardenoisien" groups of people may have only temporarily settled in small homesteads, and moved on with the shifts of the seasons accompanied by the migration of wild herds along the constantly shifting riverbeds. Maxim (1999.27-30, 221-222) thus concluded from her examination of the li-thics from Transylvania and the Par-tium area that the river valleys and the upland areas must have been inhabited by a local population before the first farmers reached this region. Paul regarded the indigenous contribution important enough to speak of a "Pracrig" culture, based on analogies with the Balkans (Paul 1995.62-67). Fig. 1. The Northern part of the Duna-Tisza interfluve area (The Jaszsag), with sites mentioned. at the turn of the 7-6th Millennium BC. From this time onwards there was a decrease in the ratio of tree pollen in the profiles. This refers to a drop in woodlands, accompanied by a wide-scale extension of furrow-weeds, signifying human activities in the landscape (Willis et al. 1995; Gdl-Juhdsz-Sumegi 2006). Besides forest clearings, traces of forming "hunters' paths" in the woodland, as well as hints of foddering animals with vegetation can also be observed in the region (Sumegi 1998; 1999). Quite obviously, and as radiocarbon dates of archeological finds testify, this was a time when the first immigrants from South-East Europe settled on the waterlogged soils stretching between the rivers Szamos and Berettyo. The flint assemblage from the pre-Neo-lithic site at Tarpa-Marki Tanya can be considered as The north-eastern part of the Alfold underwent significant transformations Fig. 2.

The process of Neolithisation in regions of the northern Great Hungarian Plain (Alfold) Studying the main characteristics of Neolithic distribution in the Balkan area, several archaeological traces point to the inference that the Neolithic infiltration into Moldavia through the Banat, and the Olt valley, and Transylvania took a different path than the variant advancing westward from the Mid-Balkans, via the mouth of the Morava River. It seems that the Alfold region has much in common with the eastern type of Neolithic transition. In recent decades, contradictory opinions have emerged about the Alfold Neolithisation. First, it was generally accepted that there were no people living in the area in the late Mesolithic; thus the first farmers arrived in a "vacuum" (Gdbori 1981). In 1982 Mak-kay came up with an entirely new idea. He ascribed the peculiar northern frontier of the Koros and Starčevo cultures in the Carpathian Basin that contradict any natural geographical obstacles, to the hostile behaviour of a local forager population (Makkay 1982. 23). In the late 80's the discovery of a real Mesolithic niche (mentioned above) in the Jaszsag area between the Danube and the Tisza created the impression that Makkay was generally right in his postulating an indigenous population, although at that time he was not able to bolster his idea with any arguments. It is also possible that this population was not equally distributed in each Alfold region, not to speak of the different activity in contacting the newcomers. Up until now the Jaszsag is the only region where the presence of this Mesolithic population could be proven. Concerning the early Neolithic development of Eastern Hungary, research was intensive in the mid-20th century, so that the first reports and evaluating studies appered in 1976 and thereafter (Kalicz, Makkay 1977; Raczky 1988; Kurucz 1989; Nagy 1998). Many decades ago, Kalicz and Makkay had already noted that the sites of the old 'Szatmar group' in North-Eastern Hungary at Nagyecsed, Tiszabezded, Tiszavalk, Tiszacsege, Ebes, ibrany and Ciumesti (Csomakoz) in the Berettyo and Szamos valley, in the Ermellek area and in the Upper Tisza region can hardly be understood without assuming intensive contacts with Transylvania (Kalicz, Makkay 1972. 1 This nomination is now out of use. 78; 1977; Makkay 1982). At some sites (e.g. Nagye-csed-Peterzug, Tiszabezded-Servapa), Koros elements were more dominant than the Linear Pottery traits in the early Alfold LBK (Szatmar II) assemblages (Kalicz, Makkay 1977.20). Based on these features, Kalicz and Makkay assigned these sites to their 'Szatmar I' group,1 together with the easternmost-lying Mehtelek, and close to it, the Romanian Homorodul de Sus (Felsohomorod) (Kalicz, Makkay 1972.92; 1977.22). Following his excavation of the Kotelek-Huszarsarok site, Raczky noted that the assemblages of the Szatmar II group "contained many formal and ornamental elements whose origins could only be explained through the Transylvanian branch of the Koros culture" (i.e. the Cri§ culture) (Raczky 1983; 1986.31; 1988.27). Thus the idea was raised that the Szatmar II group as the earliest phase of the Alfold LBK would go back to the contact between late formations of the early Neolithic: the Koros in the Alfold and the Cri§ culture arriving from the East. This hypothesis was then reinforced by analyses of smaller regions, such as Nyirseg in North-Eastern Hungary (Kurucz 1989; Starnini 1994). Early Alfold Linear Pottery sites are lacking between this area and westwards to Hortobagy. Kurucz noted that the finds from the early sites on the Szatmar plain (up to the Szamossalyi site) differed from the assemblages in more westerly areas to the extent that "any genetic relations between the two seem very doubtful" (Kurucz 1989.15). The later development in this region definitely confirms this observation. In the Middle Neolithic, this is the sole region occupied by the "Esztar-Szamos region Painted Pottery group", which is the only painted sub-group of the immense LBK culture. Between North-western Jaszsag and the North-Eastern part of the Alfold, in the Upper Tisza region, there is a contact area between the lowland and the Matra and Bukk Mountains extends. (Fig. 3) Here, the strong genetic relation between the early Alfold LBK settlements and the Koros culture can be seen. Domboroczki came to the conclusion that the LBK formulation i.e. the Neolithic transition in this area took place with practically no participation of groups other than late Koros (Domboroczki 2001; 2005). Domboroczki completed his observations by hypothesising that local forager tribes that might have lived on the edge of the Alfold most probably withdrew to the mountains, and it was only in a later 127 Eszter Banffy phase of the East Hungarian Neolithic that these groups began to merge with LBK: namely, their traces would be observed in the Tiszadob and Szil-meg groups of the developed LBK (Domboroczki 2003). Again, this inference could be reinforced by the anthropological analysis of some graves belonging to these groups (Zoffmann 2000). In connection with these ideas, it is to be noted that the original northern border of the Koros distribution along the Szolnok - River Berettyo line seems to collapse: new Koros sites are found north of this region, even in the Upper Tisza area; moreover, most recently one site, obviously connected with obsidian mining, was detected at the foot of the Tokaj Mountains.2 Again, this is data that seem to bolster Domboroczki's postulations. The later Alfold LBK groups, the Tiszadob, Szilmeg and also the Bukk formations set out from the Northern Mountains. The location of their possible local Mesolithic roots is a highly relevant assumption, which claims good arguments. Before drawing any conclusion on this question, however, some fields should be considered in detail. Such questions are signs of isolated development in pottery types and decoration. Some decorative features seem to be alien to the LBK heritage, while other new features can also be found in southern Alfold groups, like the Szakalhat, thus making their isolated highland origins questionable. Besides the basic studies and report already mentioned (Kalicz, Makkay 1977; Ku-rucz 1989; Nagy 1998; 2006), the proceedings of some further new sites along the M3 motorway, such as at Fuzesabony, Mezoszemere, Mezokovesd and Kompolt, have yielded some complementary information (Domboroczki 1997; 2003; Kalicz, Koos 1997a; 1997b; 2000; Banffy, Biro, Vaday 1997; Banffy 1999). For the earliest and developed LBK phase, however, real highland sites are also known (Csengeri 2003; 2004; Banffy 2000a). The other relevant point is the exchange system which is seen as the basis for contacts between the Alfold and the assumed highland population. On this question the research work by Bacskay and Biro are essential, shedding new light on the raw material, provenance and the typological features of chipped stone imple- Fig. 3. The Northern part of the Alfold with the adjacent Bukk, Matra mountains. a) Koros sites; b) Early Alfold LBK (Szatmar II) sites. ments within the LBK groups. (Bacskay 1976; 1982; Bacskay, Biro 1983; 1987). A further link with the Koros roots of Alfold LBK in this region is the development of cult objects. In recent excavations of the northern Alfold, plenty of peculiar animal figurines and those depicting fabulous creatures (centaurs) have come to light (Fuzesabony: Domboroczki 1996; 1997; Mezokovesd: Kalicz, Koos 1997a; 1997b). These early LBK finds can be directly traced back to the Koros culture (Dom-boroczki 2003.39). This view seems to be completed by earlier cross-cultural cultic depictions, such as bull figurines or four-legged altarpieces, that had already been considered to have lived on as Koros influences on the Alfold LBK (Kutzian 1944; Kalicz, Raczky 1981). The famous flat figurines from Meh-telek also seem to confirm the connections between the south-east European type figurative art and the early Alfold LBK, where flat, close to rectangular figurines also occur. It can be assumed that the survival of cult object types may also involve the survival of certain elements in the ritual tradition and cult life. Further important indications of characterising different ways within the Alfold development can be found when reviewing architectural traditions. The Early Neolithic houses of South-East Europe were small buildings. They were usually constructed on a square, rather than a rectangular ground plan, and they lacked an internal post structure, thus sugges- 2 I thank Pal Raczky's kind oral communication here. Janos Dani, archaeologist to the Déri Muzeum Debrecen also reported about a northernmost lying Koros site. 128 Eastern, Central and Western Hungary - variations of Neolithisation models ting a light roof. Clay was used more abundantly than wood (Lenneis 1997; 2000). The spaces outside the houses were at least equally important as the undivided intramural interior spaces, which rarely contained a hearth. East of the Tisza River, the Koros communities followed exactly this South-East European tradition in house construction. Although it has been claimed that the Koros houses actually represent the earliest, central section of Linear Pottery houses (Meier-Arendt 1989), I have found no evidence to confirm this. The Szajol-Felsofold type houses or those from the north (Krasznokvajda) differ both in their form and in their orientation from the north-oriented and heavy wood long houses of the Central European LBK (Raczky 1977; Horvath 1989; Losits 1980). Besides architecture, pottery, physical anthropological analyses and similarities in cult objects, there is one more set new results which make a direct Koros impact on the formulation of Alfold LBK groups very probable: this is new information on absolute chronology. The new dates for the latest Koros and early Alfold LBK (Szatmar II) period show a definite overlap (Whittle et al. 2002; Domboroczki 2003), thus making direct contacts possible in this part of Eastern Hungary. In sum: on the Northern fringes of the Alfold there are three regions where the phases of the Neolithic transition have been cursorily examined. In the northwestern part: at Jaszsag, there is direct evidence for late Mesolithic groups, but contact with the Koros culture has remained hypothetical as yet. In the Upper Tisza region, where the Alfold meets the Matra and Btikk Mountains, traces of a dynamic Koros expansion have been observed. According to recent data, no considerable Mesolithic participation formed the early Neolithic in this region. The forager groups may have withdrawn into the highlands, contacting LBK groups only in their developed phases - a working hypothesis which requires further research. On the North-Eastern fringe of the Alfold, the existence of a Mesolithic population could be partly shown by data from the natural sciences (i.e. by anthropogenic impacts), and partly by flint assemblages from different sites. Direct contact with early Neolithic tribes is probable, yet this still lacks direct evidence. In this case, the ear- liest Neolithic impact consisted much more of the eastern, Cri§ branch of Koros culture, rather than its Alfold variant. According to recent research, the three areas mentioned here constitute three variants of the Neolithisation process. Preneolithic Period in Transdanubia (Figure 4.) In case the existence of any pre-Neolithic (i.e. late Mesolithic) hunter-gatherer groups are assumed in Transdanubia, then these groups definitely had to face wholly new ecological circumstances in the mid-centuries of the 6th Millennium BC. In some periods, Lake Balaton split into two or three smaller lakes, with clear, cold water; when the climate turned warmer and wetter, natural dams were breached and even the northern Tapolca Basin and valleys south of the lake also became part of the lake. During these periods, the lake flooded the north to south valleys, to its south down to the Kapos River, occasionally as far as the Drava valley (Cserny 1999). At these times the Sarret bog, somewhat east of Lake Balaton became a one-meter-deep lake (Juhasz, Sumegi, Zaty-ko 2006, in press; Banffy, Juhasz, Sumegi, in press). The water level of the lake was fairly low at the end of the Mesolithic, rising significantly around 55005400 calBC. The wetter climate and the rise in the water level meant that lake shore inhabitants were forced to move away from the lowest stream shores and river terraces, and to follow the growing water level along the shores of Lake Balaton (see also: Ju-hasz, Sumegi, Zatyko 2006, in press). Despite the lack of well researched Mesolithic sites in the region, their presence in Transdanubia is partly reflected by some evidence. Such a hint is the registration of pre- Fig. 4.

Traces of this activity were observed at Szentgyorgyvolgy, near the Pityerdomb site. The soil samples taken from the waterlogged, marshy banks of the Szentgyorgy stream flowing by the site indicated intentional forest burning around 8771 BP (7936-7821 cal BC) (Cserny, Nagy-Bodor 2006). The burnt organic matter and the low level of erosion in the area suggest that forest burning was repeated fairly often, about every 15-30 years. This phenomenon is also shown in pollen data (Med-zihradszky 2001; Fuzes 1989; Zolyomi 1980; Nagy-Bodor 1988; Juhdsz 2002). The pollen profiles for the Balaton Basin and the marshland of the Little Balaton region indicate that there was a sudden increase of hazel in the mid-6th century BC, and that over one-half, 55 per cent of the ligneous species, was hazel around 5600 calBC, i.e. in the period immediately preceding the LBK (Juhdsz 2002, see also Juhdsz, Sumegi, Zatyko 2006, in press). Botanical analyses have shown that south-western Transdanu-bia was a hazel refugium during the last glaciation, and that it spread to other parts of the Carpathian Basin from this area. Still, the sudden, large-scale expansion of the species can hardly be explained without assuming active human manipulation of the environment (Bdnffy, Juhdsz, Sumegi in press). It seems likely that the growth of hazel was encouraged by forest clearance, by the creation of small clearings where this warmth-loving species yielding storable fruit with a high nutritional value could thrive. A comparison of the frequencies of hazel and cereals in the pollen diagrams is most instructive: the two are inversely proportional. The increase of cereal pollens is accompanied by a decline of hazel in the sediments. As a further hint of a Mesolithic presence, there was a pre-Neolithic boat find near Keszthely, which was no doubt used when the shoreline ran in that area, presumably still in the Mesoli-thic (Bakay, Kalicz, Sdgi 1966.76). As evidence closer to archaeology, microlithic trapezes and other types of the late Mesolithic tool-kit, collected during field surveys, have long been known from Transda-nubia. Their dating, based on their typological traits, has never been challenged (Meszdros 1948; Pusztai 1957; Dobosi 1972; Biro 1991). Most recently, a thorough excavation was begun at the Regoly Meso-lithic site, south of Lake Balaton. The preliminary results have yielded a great amount of stratified lithic instruments, although intact settlement features have not been found yet (Eichmann, Kertesz, Marton, in press). The Kapos valley and the Vazsony basin, lying north of Lake Balaton near the Szentgal mine, are especially rich in finds of this type. The stone tools examined to date were almost all made from red ra-diolarite from the Bakony Mountains. Most recently, a new project has the task of investigating some especially promising sites south of Lake Balaton, and to clarify the late Mesolithic-Starčevo interaction and LBK cultural development by excavation.3 The process of Neolithisation in Western Trans-danubia Recent research into the Neolithic of Western Trans-danubia and the findings of three micro-regional research projects made it more than probable that western Transdanubia and the Balaton region were part of a frontier zone in the mid-6th millennium BC, the setting of the long interaction between indigenous hunter-gatherer groups and immigrant Starčevo communities from the south. The probably already existing late Mesolithic horticulture (see above) was expanded with the cultivation of domestic plants after contact with Starčevo groups (Berzsenyi, Dalnoki 2006), and indigenous people also began to copy the immigrants' vessels. The result of the interaction between the two groups was the emergence of a genetically mixed population that soon colonized northern Transdanubia along the Marcal, Raba and Danube valleys, and later migrated farther along the Danube to eastern Austria, south-western Slovakia, southern Moravia and the heartland of Central Europe, where they played an active role in the transplantation of a sedentary, food-producing lifestyle. Adaptation to the changed circumstances was both an option and a bitter necessity for each. The adaptation to the cool and wet Alpine-Atlantic climate of Transdanubia, with is heavy snows in winter, must have posed a serious challenge to the Balkan immigrants. Pityerdomb, Andrashida, and perhaps Brunn II near Vienna, finds from which are rooted in the Starčevo tradition, indicate that they were capable of adapting (Banffy 2004; Simon 2002; Stadler 2005). On the other hand, a few Starčevo groups also settled in the marshland around Lake Balaton and on islets in the marshland, in an environment that meant a similar challenge for farmers of southern origin. The settlements at Gellenhaza, Vors-Ma-riaasszonysziget, Balatonlelle, and Tihany-Apati re- 3 The Kapos and Koppany valleys in southern Transdanubia are the primary targeted areas.

Kustar. 130 Eastern, Central and Western Hungary - variations of Neolithisation models fleet this different type of adaptation (Simon 1994; 1996; Kalicz, Virag, Biro 1998; Kalicz, Biro, Virag 2002; Regenye 2006, in press; Biro 2006). It follows from the rise of the Balaton water level that the one-time late Mesolithie settlements along the lakeshore are now all submerged. A closer look at the location of the plentiful early Neolithic sites around the lake reveals that they lie direetly along the changed shoreline of the period, when the water level was higher than the present one, in the marshland or on islets in the marshland (Fig. 5). This settlement pattern broadly corresponds to the Mesolithic one. These settlements all lay in close proximity to the water, in areas that were unsuited to agriculture. It is therefore possible that the majority of the settlements lying directly on the shore in the marshland had in fact been occupied by adapting Mesolithic hunter-fisher communities and those smaller groups of Balkan immigrants chose to settle in this area under their influence. If this was the case, it also implies that relations between the Starcevo groups and the indigenous population were essentially peaceful. In spite of the fact that the settlements lay in an environment that was unsuited to cultivation, macro- botanical finds from the earliest phase indicate a surprising variety of species. As to the samples from Pityerdomb, the number of remains was low for each species, never exceeding twenty specimens (Ber-zsenyi, Dalnoki 2006). The surprising variety (einkorn, spelt, common wheat, barley and edible goose-foot), but low number of cereal grains would suggest that the extent of cultivation in western Transdanu-bia and the Balaton region did not exceed that of Mesolithic horticulture - the range of plants cultivated and tended in the open areas between the houses and in the narrow zone along the shore was simply broadened with the species adopted from the Starčevo communities, together with the art of cultivation. Thus, in the formative Neolithic phase, domesticated plants may not yet have become the basis of subsistence; instead, they seem to have been a complementary source. Mesolithic impact may well be assumed in early architecture. In the northern and western Starčevo distribution, new features appear which already form a link to LBK buildings. In spite of the lack of houses on the Starčevo sites in Transdanubia, the presence of burnt daub fragments suggest that these communities lived in small- or medium-size houses (Kalicz 1993.87). Fig. 5. The Western Balaton region (satellite photo) indicating the ancient shorelines and the earliest LBK sites along. 131 Eszter Banffy In the earliest phase, early Central European LBK houses were single roomed, with a southern and northern part added at some later date. Extramural activates were performed in pits, many of which had some sort of protective roofing, especially in the northern part. These phenomena can primarily be explained by the climate, with cultural traditions playing a secondary role only. It would appear that the central section of the Central European Linear Pottery houses evolved first. Timber played an increasingly important role in the construction of these buildings. The size of the two houses excavated at Szentgyorgyvolgy-Pityerdomb (Banffy 2000b; 2004), the combined use of timber and clay, and the northern orientation appear to have been adopted from the pre-Linear Pottery period. The long pits flanking the longitudinal walls are first documented at this site. We may therefore assume that both Mesolithic and Starčevo influences played a role in the emergence of Linear Pottery houses, as did the environment and climate. Contacts can also be analysed by examining early pottery in Transdanubia. Significant differences can be noted between the pottery assemblages from the late Starčevo settlements in western Transdanubia and the Balaton region, and those from southern Transdanubian and more southerly sites. This difference, reflected in the finds from Szentgyorgyvolgy-Pityerdomb and a number of other settlements, can most likely be attributed to the cultural impact of indigenous hunter-gatherer groups (Simon 1996; 2002; Banffy 2004). The examination and interpretation of cult finds leads to a similar conclusion (Banffy 2005). The appearance of the cult objects of the South-East European Neolithic in transitional assemblages, such as the one from Pityerdomb, and, later, of their copies, again indicates some form of interaction between the two populations. There was no trace of the rich diversity of the Early Neolithic statuary of the Balkans either at Pityerdomb. This would suggest that some of the cult paraphernalia were adopted and used by the formative Linear Pottery communities, while others were discarded. Neither can we reject the possibility that certain elements of the cult inventory were adopted or copied for prestige reasons, as in the case of other Neolithic innovations, perhaps as the reflection of an incipient social ranking in these indigenous communities. It is my belief that the local copies of cult objects and the drastic decline in statuary can be explained by the cultural impact of indigenous hunter-gatherer groups in the mixed po- pulation forming the early Linear Pottery communities. The survival of the Mesolithic lifestyle in the transitional period can also be traced in the chipped stone inventory. The rich lithic assemblage found near Vo-rosto and Mencshely, two Linear Pottery sites in the Vazsony basin by the northern shore of Lake Balaton, is in the late Mesolithic Tardenoisien microlithic tradition. A closer examination of the stone artefacts reveal traces of sickle gloss on a few samples. There are two possible explanations: the sickle gloss can be attributed to their use in Mesolithic horticulture, or the lithics came from an early Linear Pottery settlement preceding the occupation in the classical phase (Biro 2001; 2002b). An interesting observation is that the disappearance of this tool-kit coincided with changes in settlement patterns and subsistence at the beginning of the developed Transda-nubian LBK, the Keszthely phase - the very period when the occupants of the Transdanubian settlements began to use the more simple range of tools generally characterizing Linear Pottery cultures, restricted to sickle blades and a few other types (Biro 1991; 2001; 2002a; 2002b). The indigenous Mesolithic groups were clearly part of the mobile hunter-fisher-gatherer population whose stone tools and other remains have been found in the Vazsony basin in the Balaton Uplands, in the Little Balaton region, and in the Szentgyorgyvolgy area. The interaction between the two populations probably meant that the two distinct lifestyles and sets of values acted as a stimulus, while their mutual reliance on each other no doubt contributed to mini-malizing conflicts, promoting peaceful co-existence, or even the joint occupation of settlements. This long-running process of gradual change suggests that the statement that the so-called "Neolithic revolution" i.e. the radical change in subsistence did not happen in the initial phases of the West Transdanu-bian Neolithic, but one phase later. In Transdanubia the major change in lifestyles and subsistence patterns occurred not at the beginning of the Neolithic, as earlier believed, but some three or four generations later. The problems of Neolithisation in Eastern and Northern Transdanubia (Figure 6) Among the fairly intensive LBK sites from County Fejer, North-Eastern Transdanubia (Makkay 1970; 1978), the fairly intensive presence of only the deve- 132 Eastern, Central and Western Hungary - variations of Neolithisation models loped phases can be confirmed. Among these, the Bicske site is the only exception dated to the older phase. It was named as the eponymous site for the older Transdanubian LBK by Makkay. However, it seems that it may not represent the initial, oldest phase of the culture (Banffy, Oross in press). There are several regions in Transdanubia where both the oldest, Sarmellek-Pityerdomb typed pottery, and also the slightly later Bicske typed pottery, are present. First, the possibility had to be maintained that this phenomenon may well be treated as a geographical difference, since there has not been abundant data for assuming the opposite. In north-eastern Transda-nubia, for decades the Bicske typed material had been the only representative of the old LBK, before a new site was excavated in by Kalicz-Schreiber and Kalicz (Kalicz-Schreiber, Kalicz 1992; Kalicz, Ka-licz-Schreiber 2002). Budapest-Aranyhegyi Road, lying in the marshy plain of the Danube bank in Aquincum, northern Buda. It was dated to the older LBK phase. Interestingly enough, older LBK sites did not grow with time and increasing research intensity. The topographic description of the region of Esztergom and Dorog (north-west of Budapest) contains no hints of LBK sherds that could be dated to the older phase (Horvath, Kelemen, Torma 1979). As we shall see, along the northern banks of the river i.e. in South-western Slovakia, the situation is the same. Pavuk himself was unable to present sites of this type either along the Danube, or in the Csal-lokoz area on his most recent, 1994 map (Pavuk 1994.147). The reason for this hiatus remains enigmatic. The contacts of the Linear Pottery sites in the Burgenland and Lower Austria with Transdanubia suggest that the main route of migration led through the Danube valley. It is to be hoped that future investigations will resolve this issue. In connection with these observations, Pavuk's hypothesis of Neolithi-sation in South-western Slovakia is worth mentioning. These views, essentially unchanged for long decades,4 can be rejected on the basis of the following arguments. While accepting J. Lichardus' earlier "proto-Li-nienbandkeramik" theory (Lichardus 1972), Pavuk made two claims (Pavuk 1962; 1972; 1980a; 1980b; 1994). The first of these was that Linear Pot- tery society and lifestyle developed in south-eastern Slovakia. The other, the more bizarre aspect of his thesis, concerned the date of the emergence of Linear Pottery. Pavuk dissociated Linear Pottery development from the cultural and ethnic influence of the Balkans, both in the Great Hungarian Plain and in Transdanubia, the latter being the more interesting of the two areas, owing to its proximity to Slovakia. In his opinion, the transition and the first use of pottery were not only entirely independent of the Ko-ros-Starčevo culture and its possible effects on the Nitra Basin, but actually began much earlier than the generally accepted late Starčevo period, namely, in the period corresponding to the early/classic Starčevo phase. Pavuk attributed the undeniable similarities between late Starčevo and Linear Pottery to the later, southern expansion of groups from the Nitra Basin, during the course of which the Linear Pottery groups interacted with the Starčevo communities of the Spiraloid B phase in Transdanubia. He distinguished four sub-phases in the early Linear Pottery phase of western Slovakia - the Nitra, the Hurbano-vo, the Bina and the Milanovce phases - in order to demonstrate the complexity and long duration of the process (Pavuk 1980a.40-47). This categorization is uncertain and controversial, to say the least, since it is based exclusively on the manufacturing technique and the (rather rare) ornamental motifs of the pottery. Only at Bina were fine, biconical wares found; the pottery from the other sites is dominated by thick-walled household pottery. Fig. 6. North-Eastern Transdanubia with the adjacent Godollo hills and Jdszsdg region to the east with early LBK sites mentioned. 4 Most recently in Zvelebil M., Lukes A. (eds.), LBK dialogues. Oxford 2004. 133 Eszter Banffy It is very difficult, if not downright impossible to set up a finer typological classification and to distinguish chronological horizons on the basis of coarse pottery, a handful of mostly surface finds.5 Most of the pottery in question was admittedly recovered from smaller soundings and a handful of pits uncovered during small-scale excavations; very few represent closed assemblages and the "Hurbanovo phase" is exclusively based on a few surface finds. The Nitra type pottery can best be linked to the early Linear Pottery in the Balaton region; indeed: the absence fine wares and ornamentation can also be observed in assemblages of the type found in several sites, e.g. Sarmel-lek, Revfulop, Balatonszepezd, Tapolca-Plebaniakert (Banffy 2004.334-344). The Nitra Basin groups were unlikely to have invented pottery making on their own; a more likely possibility is that they adopted this innovation together with other elements of the Neolithic package from groups on the fringes of the Starcevo distribution, or rather from those groups born from the (intermarriage) mixing of southern immigrants and indigenous groups. It would seem that as a result of the cultural influences affecting Transdanubia, the indigenous groups inhabiting the northern part of the Little Hungarian Plain, too, tried their hand at pottery making. In a recent study, Petrasch (2001) examined the problem of the Linear Pottery 'homeland' from a demo-graphically. According to his estimates, northern Transdanubia, south-west Slovakia, the Burgenland and Lower Austria, could at the most have had a population of five thousand at the dawn of the Neolithic. Petrasch concluded that this region was more probably the first stop in the Linear Pottery expansion, rather than its point of departure. He also noted that Linear Pottery probably evolved in the Zala and Bakony region and the southern part of the area around Lake Ferto, i.e. western Transdanubia (Petrasch 2001.17). Most recently, it occurred also east of the Danube that assemblages very similar to those from Buda-pest-Aranyhegyi Road have been found. Apart from very dense settelment in the developed LBK phases, the site at Galgaheviz contained pottery fragments of the oldest LBK phase (Kalicz, Kalicz-Schreiber 2002.29-30). Similarly, the oldest LBK vessel profile comes from Ipolydamasd, unfortunately a surface find (Torma 1993.111, site 9/4 and Pl. 1). Even with the help of these scattered finds it is not possible to answer questions about Neolithisation in north-east Transdanubia. These data, on the contrary, raise some new questions about the hypothetical contacts of Transdanubian LBK and the Late Mesolithic/Early Neolithic of the Jaszsag area, and also possible connections to the Szatmar II group, i.e. the earliest LBK in the Matra-Bukk fringes of the Alfold. When contrasting this peculiar phenomenon to the intensive Koros occupation of the Southern part of the Duna-Tisza heartland, which suddenly stopped south of the Jaszsag, a very new model of various Neolithisation types start to form. Certainly, much more data will be necessary even to make the questions more adequate, not to speak of the answers. The possible causes of the differences The first and most adequate answer for the different modes of Neolithic transition, in other words, Neoli-thisation models within a rather small geographical area, could be found in the different ratios and communication with local tribes (Fig. 7). There are two regions, the Drava Valley and the fringes of the Al-fold at the Bukk-Matra Mountains, where intensive Southern immigration dominated over the possible indigenous population, whose participation in the Neolithic package was weak. The Jaszsag area represents the other pole, according to our present knowledge. Here the indigenous groups are clearly present, but it seems that the real Koros sites, as well as transitional settlements that could represent contacts between the groups of different subsistence, are scarcely present. We found two regions: Western Transdanubia, including Lake Balaton and the northeastern edge of the Alfold (the Nyirseg), where it is highly probable that indigenous foragers came into contact with Starčevo groups in the first case, and Cri§ groups, in the second case. There are no real ideas as yet about the Neolithisation process in the north-eastern Transdanubian and the Budapest area, including the problem that the sporadic earliest Transdanubian (Central European) LBK sites are geographically very close to the Jaszsag, but this only compounds the problem. The second type of answer should be sought in the ecological barrier hypothesis (Sumegi, Kertesz 2001, Sumegi, Kertesz, Hertelen-di 2002). In spite of the total misunderstanding valuations of this idea (Makkay 2003.34-37), this hy- 5 In contrast to the few dozen sherds categorized by Pavuk, Otto Trogmayer examined tens of thousands of pottery fragments and was still unable to establish the internal chronology of the Koros culture (Trogmayer 1968). The lack of an internal chronology for the Koros culture is one of the great debts of Hungarian prehistoric research. M. Cladders' analyses of Linear Pottery wares yielded a similar result: in her opinion the differences can be traced to regional, rather than chronological differences (Cladders 1995). 134 Eastern, Central and Western Hungary - variations of Neolithisation models pothesis about a Central European Agro-Ecological Barrier (CEB AEB) is not a frontier dividing the two groups of different subsistence modes from each other. On the contrary, this barrier means that the climatic situation would make the migration of Balkan farmers increasingly slower, until reaching an area in which for some species of the Neolithic package, including floral and faunal elements, it became hard or impossible to survive. Such species could be e.g. caprinae (sheep and goat) in the Western Trans-danubian Atlantic climate, where in the wet winters, with high and long-lasting snow; short-legged animals would sink into the snow, dying before the spring of pneumonia and other disease. This all means that people who migrated from the South would have had to stop or move north or west much more slowly than earlier. This is the negative impulse. The ecological barrier also has a positive impact on the Neolithisation process. This lies in the longer time spent in one area, thus making it possible for small indigenous to come into closer personal, cultural and exchange contacts with the newcomers. A typical area for this longer-lasting process is the Balaton region, where co-existence is shown by several direct and indirect archeological and other evidence (Bdnffy 2000b; 2004; 2005). A further, significant difference in the Neolithic transition can be observed between the two major regions, the Transdanubian and the East Hungarian, Alfold area. This difference can be more easily observed when examining their persistence in the Middle Neolithic, which was caused by divergent modes of Neolithisation. During the whole life of the LBK, the distribution area remained roughly the same in the East, with no extension during the developed phases: from the Tisza to the Koros River regions and the Partium. The process in Transdanubia was just the opposite. Within a few generations, 80-120 years, the Transdanubian early LBK groups, i.e. a genetic and cultural mixture of indigenous foragers and Balkan farmers, had occupied a vast area covering a major part of Europe between the Paris Basin and south-east Poland. There must be diverse strategies hidden behind these major differences. The eastern group chose an inceasingly intense settlement pattern, and agriculture that led to the formations of real tell settlements. This process must have happened together with an intensifying social stratification, hereditary social ranking, the intensive development of symbols and ritual life, and practically with the formation of a pre-urban society very similar to the Near Eastern model. Not unimportantly, it shows considerably more complexity than the economy of the previous periods. Agriculture, stock breeding played the main role, and, according to the social rank that must have been formulated by the Late Neolithic, all these activities must have been organised to a formerly unknown level. The Alfold Linear pottery groups had every opportunity to exploit their rich soils and they were also in a position to develop intensive exchange relationships with their eastern neighbours. In other words, they were able to keep their settlements flourishing without migrations. This could be a prime reason for intensive internal expansion and social development without any changes in the Alfold distribution area. Thus, the Alfold region may have had the function of a "central site" from the Middle to the Late Neolithic. Nevertheless, this process seems to have had an end in its gestation stage (Banffy 2002). The uppermost layers on numerous tell settlements show clearly how the mounds were abandoned at the dawn of the Copper Age (roughly around 4400 BC). In Transdanubia, the keys to finding a reason behind the rapid distribution of the Western LBK are probably longdistance exchange and cultural contact. The causes behind the expansion and the survival of the contact networks may have been based on similar reasons, but the position of Trans-danubia was determined by the lack of the Alfold conditions on the one Fig. 7. Key areas of studying the neolithic transition within Hungary. Regions marked in yellow: stronger Koros/Starcevo impact; regions marked in blue: stronger Pre-Neolithic impact. 135 Eszter Banffy hand, some pressing contingencies and waves of migration on the other. The expansion into the heartland of Central Europe was so rapid that it left no typological differences in the archaeological record (Quitta 1960; 1971), nor can the successive phases be pinpointed with radiocarbon dates (Gläser 1991; Lenneis, Stadler, Windl 1996; Bánffy, Oross in press). One obvious explanation was to invoke rapid population growth for this swift expansion, based on the examples from the ancient Near East. In his quoted study on the demographic data for the Early Neolithic, Petrasch shattered any illusions about this theory, arguing that early LBK population growth could have been no more than 0.1 per cent (Petrasch 2001.18). Another probable explanation is offered by Anthony, when he writes of some positive triggers for migration, such as low population density, fertile soil, proximity to water, good climate etc. (Anthony 1992. 898). 'Push' forces, such as over-population or climatic deterioration, can be rejected in the case of the LBK expansion. In contrast, there is evidence for each of the "pull" forces. If exchange relations can also be created and maintained, an area of this type usually attracts settlers. "Migration is a social strategy" (Anthony 1997.22). Justifying this idea, the evidence for communication and contact networks between Transdanubia and the regions to its northwest can be reflected e.g. in the presence of Szentgál ra-diolarite in Moravia, and in Germany, being only modest indications of these networks in the archaeological records. Since there had to be a mutual interest forming the basis of these contact relations, the pre-historian would search for something the early Trans-danubian farmers could be in need of, since north of Bosnia there is no source of salt in the whole region (Tasic 2000.39). This is not to say that the commodity in return may not have been salt. This idea occurs when examining the Bad Nauheim-Niedermörlen settlement north of Frankfurt/Main (Schade-Lin-dig 2002a; 2002b). The finds from this site reflected surprisingly strong ties with Transdanubia. Bad Nauheim lies in an area rich in salt. Saile argues for the early Neolithic exploitation of salt mines in Westphalia and Lower Saxony (Saile 2001. 150-151). It is therefore possible that this easily transportable and valuable commodity, essential to diet, for food preservation, and for animal husbandry, was exchanged for various articles from the Danube valley. One could certainly object that the rich salt area at Hallstatt near Salzburg in the Upper Austrian region lies much closer. However, the distribution of Early Neolithic sites indicates that the migration route led along the northern Danube bank, through the Munich basin to southwest Germany. In this way, the salt mines in Hallstatt were unknown and can thus be rejected as a possible source. LBK communities of Transdanubia sought to acquire salt from regions with which they were familiar, in part as a result of their pre-Neolithic contacts, and in part from the knowledge acquired during their primary migrations - in other words, from the northwest. This probably enhanced the importance of the Wetterau and Aldenhoven region. In spite of the many differences, some similarity can also be noted between Neolithization in Transdanubia and the Upper Tisza region. It has been repeatedly noted that riverside settlements in the area between the Great Hungarian Plain and the mountainous region to its north acted as a kind of 'marketplace' for the interaction: the possible co-existence and mixing of groups with different lifestyles during different periods of the Neolithic and the Copper Age in Hungary (Kalicz 1994; Raczky et al. 1994; Banffy 1999). In this respect the northern Alfold fringes resemble western Transdanubia and the Balaton region, where interaction between different groups was stimulated by the trade in Szentgal radiolarite. In the Northern Mountain Range, the most valuable raw materials were limnoquartzite from the Matra Mountains and obsidian from Tokaj. The stone tools found on early Alfold Linear Pottery sites and also on Koros sites were predominantly manufactured from these two rocks (Kalicz-Makkay 1976.23; Star-nini 1994; 2000; 2001; Biro 2001; 2002b; Maxim 1999). If we accept the Mesolithic presence in the mountains, it is not to exclude the possibility that these precious raw material sources were controlled by these groups both in Transdanubia and in the Northern Mountain Range, and that the main cause and incentive for the interaction was the trade in these lithics. The indigenous groups presumably received Neolithic technologies in exchange for the li-thic raw material in the Great Hungarian Plain, too, similarly to the situation assumed for Transdanubia. In this sketch of the Mesolithic-Neolithic transition and early Neolithic formations, which appeared so differently in small regions within Eastern and Western Hungary, it seems that working hypotheses with question marks are more numerous than answers. Nevertheless, beforehand there were hardly any questions put. This stage is, in my opinion, a step forward that reflects the present state of research. 136 Eastern, Central and Western Hungary - variations of Neolithisation models REFERENCES ANTHONY D. W. 1992.

They consisted in the emergence and expansion of new systems of circulating information ('communicative communities'). The majority of these were connected with the Neolithic. The process involved a constant clash between foreign and local patterns. The latter, over time, prevailed. Hence the ultimate dominance of Neolithic communicative communities in the eastern part of Central Europe around the middle of the fourth millennium was essentially a local development. Nonetheless, a considerable portion of the territory continued to remain outside their influence. Therefore, throughout the three millennia, Mesolithic communicative communities not only gradually merged with or evolved into Neolithic ones. They also embraced such transformations, mainly concerning the material culture and ideology, which were completely independent from the advances of the Neolithic, or could have been competitive in relation to them. IZVLEČEK - V šestem, petem in četrtem tisočletju BC so se ob Visli in Odri dogajale izjemno kompleksne ekonomske, socialne in ideološke spremembe. Vključevale so pojav in širjenje novih sistemov distribucije informacij ('skupnosti, ki komunicirajo'). Večina jih je bila povezanih z neolitikom. Proces je vključeval stalna nasprotja med tujimi in lokalnimi vzorci. Slednji so sčasoma prevladali. Zato je bila dokončna nadvlada neolitskih 'skupnosti, ki komunicirajo' v vzhodnem delu srednje Evrope okoli sredine četrtega tisočletja v bistvu lokalni razvoj. Vendar je ostal velik del omenjenega teritorija še naprej izven njihovega vpliva. Zato se mezolitske 'skupnosti, ki komunicirajo' skozi tri tisočletja niso le postopoma zlile z neolitskimi ali razvile v njih. Vključevale so tudi transformacije materialne kulture in ideologije, ki so bile popolnoma neodvisne od neolitskega napredka ali so mu bile celo konkurenčne. KEY WORDS - East-Central Europe; Late Mesolithic; Neolithic; Neolithisation; foreign and local patterns Introduction The topic of this paper is the transformations that took place in the eastern part of Central Europe between 6000 and 3000 BC. My general thesis is that foreign influences and foreign systems in circulating information that were certainly present during that period caused indigenous reactions leading to the creation of such systems at the local level which consisted of indigenous elements, as well as select- ed external ones. I took the liberty of calling these systems, both foreign and local, 'communicative communities' (Verkehrsgemeinschaft), using the term applied by a Polish philologist Ludwik Zabrocki (1963), whose work focused on German historical and geographical dialectology. It must be strongly stressed that his term is not, or in any case does not have to be, equivalent to a linguistic community. 3 Marek Nowak "It is not necessary for a communicative community to have at its disposal only one medium of communication. A communicative community may use various media of communication, that is various languages. (...) every linguistic community is or was also a communicative community, but not every communicative community is a linguistic community." (Zabrocki 1963.27-28 translated by M. Kapera) It appears that a communicative community may embrace a number, large or small, of linguistic communities. Basically, Zabrocki's approach pertained to the dimension of language, which is obviously connected with the fact that the quoted study discussed exclusively philological matters. However, it is my conviction that it is worthwhile transplanting the term 'communicative community' to other, non-linguistic fields (Parczewski 2000), although it remains debatable whether it should be actually linked with the traditional notion of archaeological culture. Such a correlation is problematic even due to the meanings embedded in material culture (Hodder 1992.12-14; 1995.16; Tilley 1999; Thomas 1996. 59). Yet this term should refer to the above mentioned system of circulating information, and strictly speaking to those parts of it whose meanings were understood and approved of (or perhaps also imposed on) particular people. It is to be concluded then that the term 'system of circulating information' is a more general one and, in a sense, more comprehensive than the term 'communicative community': thanks to circulating information, members of a community may become aware of things and behaviours which are not understood by them, the hidden meaning of which cannot be grasped by them. So, let me emphasise once again, a 'communicative community' would include this part of the system of circulating information that is understood and approved of, even subconsciously, as metaphorical meanings have to be taken into account, as well1. Usually the nature of the problem is concealed from us, and a given communicative community embraces a multitude of phenomena and meanings of various kinds. In the discussed period of time and area, there may have been very many such communities, not entirely overlapping from the point of view of chorology and chronology. I will also argue that the communicative communities present in East-Central Europe between 6000 Fig. 1.

From 6000 to 4800 BC There are perhaps hundreds of Mesolithic sites, especially in northern and central Poland, that can be dated to the sixth millennium BC. They are grouped into two main division: the so-called Janistawice Culture and post-Maglemosian Complex (Fig. 1), comprising several smaller archaeological groupings. There are also relics of an older Duvensee archaeological tradition, which in Poland was distinguished as Komornica Culture (Galinski 2002; Kobusiewicz 1999; Koztowski 1989; Koztowski, Koztowski 1986). Whereas Neolithisation is the most important aspect here, one should also briefly mention the site of D^by 29, in the region of Kuyavia (Fig. 1), which caused much controversy (Domanska 1989; 1990; 1998). In the fossil soil, under sand cover, numerous flints were found, as well as roughly two thousand animal bones. Among them, Lasota-Moskalewska 1 Of course it is an open question whether such term is the most accurate, and reflects the essence of the problem. One can come across a variety of similar terms which in my view have approximately the same connotations: 'interaction sphere' (Caldwell, after Tabaczynski 2000.260), 'interpretative community' (Mamzer 2004.120-4), 'homologous lineages' (Shennan 2000.833), 'system of circulating cultural information' (Czebreszuk 2001.15), 'communication systems' (Raczky, Anders 2003.171). 144 Transformations in East-Central Europe from 6000 to 3000 BC> local vs. foreign patterns Fig. 2. LBK-like pottery from the site of Podgaj 11 (Kuyavia, district Aleksandrow Kujawski); after Czerniak 1994. (1998) identified several tens as bones of domesticated animals. However, the site findings aroused an extremely lively discussion. Opponents argued that there was no proof of homogeneity of the fossil soil, and consequently, the bones of domesticates may have been an admixture from the humic soil. Besides, there were also some doubts as to whether the bones were actually from domesticated animals (Czerniak 1994.8-10; Kozlowski 1991; 1998; Nie-siolowska-Sreniowska 1998b). To sum up, I would say that the site even to date is still open to interpretation. At the same time, it provides a good example of the serious problems involved in the homogeneity of sand sites. The first Neolithic sites in Poland (of Linear Band Pottery Culture, i.e. LBK) can be dated back to the beginning of the second half of the sixth millennium BC (Bogucki 2000; 2001; 2003; Czerniak 1994; Kul-czycka-Leciejewiczowa 1988; 2000). They appear in southern Poland, as well as in the lowlands of Ku-yavia and the Chelmno Land (Fig. 1). It is my belief, perhaps somewhat old-fashioned, that their appearance was a result of direct migrations by LBK farmers from the south, mainly from Moravia. From 54/53 centuries BC onwards, there was a considerable increase in the number of the LBK sites and of the LBK territorial range; however, the most of the sites were still concentrated within enclaves. All these enclaves comprise the most fertile soils. Certainly, there are also single sites of the LBK outside these enclaves, which reflect a relatively frequent penetration of less fertile areas in mountain, upland and lowland zones (Fig. 1). Very interesting in this respect are the recently discovered sites of this culture in Eastern Pomerania (Bojarski et al. 2001.56; Bokiniec et al. 2003.36; 2004.30; Paner et al. 2003), e. g. Brody Pomorskie and Koscielna Jania (Paner 2001.40; Paner et al. 2004.25), because they belong to the northernmost sites of the LBK. Equally interesting seem to be sites of the Podgaj 32 type that contain Mesolithic-like flint tools and LBK pottery, but only its coarse variety (Fig. 2) (Czerniak 1994.54-58; Domanska 2003). These sites are located on sands, yet on the outskirts of a central Kuyavian patch of black soils (Fig. 1). Generally speaking, in this case two interpretations are applicable: i) this was a Mesolithic group, with selected LBK pottery; ii) this was an LBK group, with Mesoli-thic flints. Consequently, I am of the opinion that in the case of Podgaj 32 sites, we are dealing with a r- -— tM -v_Ja r fS-1 - 3 -4 A -5 (\J\) -6 4-7 9.... 5° 100."" Fig. 3.

Moreover, I would like to underline that there are a large number of Mesolithic sites that can be dated to the period between 5500 and 4800 BC (Bagniew-ski 1979; 1987; 1996; 1999; 2000; Koziowski 1989; Kobusiewicz 1999), some of them either right within LBK enclaves or on their outskirts, like in the region of Kuyavia (Fig. 1) (Domanska 2003). One site of this kind is a recently excavated one at Glanow (Pazdur et al. 2005; Zajqc 2001): a very large, multi-period settlement, actually located close to an LBK settlement area. The late Mesolithic phase of the settlement partly overlapped with the LBK. From 4800 to 4000 BC When the LBK disappeared, the situation still remained bi-modal (Fig. 3). We have the same Mesoli-thic units, namely post-Maglemosian groups, including the so-called Bobr group in Lower Silesia, Jani-slawice Culture, and the remnants of Komornica Cul- ture (Bagniewski 1998; 2001; Kobusiewicz 1999; Koziowski 1989). As regards Neolithic units, in theory, we have Stroke Band Pottery Culture in the aforementioned enclaves in western Poland and the Lengyel-Polgar Complex in south-eastern Poland. However, in practice, we observe very distinct stroke elements in the latter groups, as well as Lengyel-Pol-gar elements in a Stroke Band context (Czerniak 1994; Kaczanowska et al. 1986; Kaczanowska, Koziowski 1994; Kadrow, Zakoscielna 2000; Ka-mienska, Koziowski 1990; Kirkowski 1994; Koziowski 2004; Kulczycka-Leciejewiczowa 2002; Prus 1977). These phenomena sometimes lead to terminological disorientation. One of the suggested solutions to this problem was the term 'Late Band Pottery Culture', introduced and used by pre-historians of the Poznan school of Neolithic archaeology (Czerniak 1980; 1994). This term refers to lowland, post-LBK Neolithic communities, although the main reason it was introduced was a belief in the direct con- Fig. 5.

Luckily, after ca. 4500 BC, the situation becomes clearer, because Stroke Band Pottery ceased to exist, replaced by the Lengyel-Polgar. There are also single Neolithic, post-LBK sites outside early Neolithic enclaves (Bagniewski 2002; Bojarski et al. 2001.55; Felczak 1998; 2005; Jankowska 1999; 2001). Of particular interest in this case are the recently discovered northernmost sites at Barlozno (Paner 2001.38-42; Paner et al. 2004.22-24) and Rownina Dolna (Fig. 4) (Rybicka, Rzepecki 2001; Rybicka, Wysocki 2004). Most probably, in this period there appeared also groupings that can be included in the para-Neolithic formation, i.e. foraging populations that produced and used their own, unique pottery. They generally knew agriculture, but did not apply it in practice in any greater measure (Dolukhanov et al. 2005; Ri-mantiene 1992; Werbart 1998; Zvelebil 1993). Referring to the "Polish" para-Neolithic in the fifth millennium, we can speak of the early stages of Neman Culture and Zedmar Culture (Fig. 3) (Guminski 1998; 1999a; 2003b; Jozwiak 2003; Kempisty 1986; Kem-pisty, Sulgostowska 1991; Kempisty, Wiqckowska 1983). There are also single Mesolithic sites with pottery outside the scope of the aforementioned units dated to the period under consideration. Four of them (D^bki, Koszalin-Dzierz^cino, Tanowo, Chobienice) contain pottery (Fig. 5) that is similar to the pottery of Erteb0lle Culture (Galinski 1987; 1988; 1992; Il-kiewicz 1989; 1997; Kabacinski 2001; Kobusie-wicz, Kabacinski 1998); therefore they are very often considered as the south-easternmost sites of this culture. As a matter of fact, they belong to Erte-b0lle Culture only as regards ceramics. The flint assemblages are of purely local, that is post-Maglemo-sian, type (ibid.). So, overall, we can again notice here a blend of local and foreign elements. From 4000 to 3000 BC After ca. 4000 BC the situation changed significantly (Fig. 6). The Lengyel-Polgar tradition was gradually vanishing, whereas a new Neolithic unit had appeared: Funnel Beaker Culture (i.e. TRB) (Burchard et al. 1991; Czerniak et al. 1990; Midgley 1992; 2002). This unit is the first Neolithic phenomenon that was Fig. 7. Early Linin pottery (with TRB traits), from the territory of Masovia; after Kempisty 1972.1 -Dqbrowa (district Wolomin), 2 - Wiqzowna (district Otwock), 3 - Grzegorzewo (district Wolomin), 4 - Dzialy Czarnowskie (district Wolomin). 147 Marek Nowak Fig. 8. East-Central Europe from 6000 to 4000 BC; flint perspective. 1 - Early Neolithic flint industry (LBK, SBK and early Lengyel-Polgar), 2 - Late Me-solithic type of flint industry (late Mesolithic and para-Neolithic), 3 - selected, single Early Neolithic sites, K - the latest sites of the Komornica Culture. present literally everywhere, and not only within small enclaves (Kruk 1980; Kruk, Milisauskas 1999; Nowak 1993; 2001; Pelisiak 2003; Rybicka 2004). Therefore, we can consider the spread of this culture as the second stage of Neolithisation of East-Central Europe. There are also differences between the spatial layout of the LBK, post-LBK and TRB in the aforementioned enclaves of early Neolithic settlement. Relatively few LBK and Lengyel-Polgar sites tend to be concentrated in clusters. As to TRB sites, there are much more of them, usually scattered throughout the area (Czer-niak 1994; Kruk et al. 1996; Milisauskas, Kruk 1984; Sosnowski 1994). The genesis of the TRB is one of the most disputed and controversial issues in European prehistory (Bo-gucki 1996; 1998; Czerniak 1994; Czerniak, Kosko 1993; Domanska 1995; Galinski 1991; Gebauer 1995; Jankowska, Wislanski 1991; Jennbert 1998; Keeley 1992; Kukawka 1997; Price 1996; Price, Gebauer, Keely 1995; Rzepecki 2004; Sherratt 1990; Whittle 1996.204-10; Wislanski 1979; Zvelebil 2001; Zvelebil, Dolukhanov 1991). Although many Polish archaeologists would surely argue against this statement, I think that we should seek the roots of 'Polish' TRB pottery outside, in Schleswig-Holstein and the area of the lower Elbe. This does not imply northwestern migration, but a very extensive and relati- vely quick spread of a new ceramic fashion among both farming and foraging populations in East-Central Europe. Certainly, with time, 'Polish' TRB pottery acquired more and more unique features, as compared to pottery from the areas of primary origin. Thus the TRB in Poland, in its entirety, is in fact a combination of foreign patterns, as well as many local traditions in pottery-making. At about 4500 BC, the last Lengyel-Polgar groups disappeared, but a new southern factor emerged, Baden Culture (Fig. 6). It was probably a result of direct migration from south-western Slovakia to Little Poland (the region of Krakow) (Zastawny 1999; 2000). Again, an intense process occurred through which Baden pottery stylistics were adopted by some TRB populations. This blend was very strong in western Little Poland (Kruk, Milisauskas 1983; 1990; 1999), Upper Silesia (Bukowska-Gedigowa 1980) and Kuyavia (Kosko 1989; Wislanski 1979.194197), and it is noticeable in some other regions, albeit in a weaker form. The mid-fourth millennium BC was also, in my opinion, the starting point of the next pottery style of local origin, that is Globular Amphorae Culture, although, according to Marzena Szmyt (1996), its beginnings are even earlier. Fig. 9. Flint tools of the LBK; after Balcer 1983. 148 Transformations in East-Central Europe from 6000 to 3000 BC> local vs. foreign patterns Fig. 10. Late Mesolithic flint tools from Dqbrowa Krqpnica (Lower Silesia, district Boleslawiec); after Bagniewski 1982. Fig. 11. Late Mesolithic (with para-Neolithic elements) flint tools from Sosnia (Podlasie, district Grajewo); after Kempisty, Wi^ckowska 1983. Another fascinating phenomenon is the widespread presence of para-Neolithic pottery in the basins of the Vistula and the Oder (Fig. 6). It is connected mainly with Neman Culture and Zedmar Culture and, to some extent, with Comb Pottery Culture (Cyrek 1990; Cyrek et al. 1985; Galinski 1991; Guminski 1998; 1999a; 1999b; 2003a; 2003b; Jozwiak 2003; Kempisty 1986; Kempisty, Sulgostowska 1991; Kempisty, Wiqckowska 1983; Kobusiewicz, Kaba-cinski 1993). In my opinion, pottery of this kind was taken by local Mesolithic communities from their eastern foraging neighbours and incorporated into their information system. Traces of possible eastern migrations can be seen only on the north-eastern fringes of today's Poland. To make the picture of the fourth millennium BC complete, it must be added that some Mesolithic sites that do not include pottery are radiocarbon-dated to that period (Fig. 6) (Bagniewski 1982; 1990; Niesiolowska-Sreniowska 1990; 1998a). However, this is not the end of the story of mergers. There is also para-Neolithic pottery that contains some Neolithic, Funnel Beaker features, and perhaps also Globular Amphorae features (Figs. 6, 7). In Poland, pottery of this kind is respectively defined as Fig. 12. East-Central Europe from 4000 to 3000 BC; flint perspective. 1 - 'macrolithic' Middle Neolithic flint industry (late Lengyel-Polgar and part of the TRB), 2 - 'Late Mesolithic' type of flint industry (the latest Mesolithic, para-Neolithic, and part of the TRB), 3 - Middle Neolithic flint industry based on local raw materials (part of the TRB). 149 Marek Nowak Fig. 13. Late Lengyel-Polgar flint tools; after Balcer 1983. Linin types A and B, according to Elzbieta Kempisty (1986). In fact, the pottery of Zedmar Culture also displays distinct Neolithic characteristics, as claimed by Witold Guminski (1999b; 2003b). Flint perspective The previously presented transformations referred to traditional archaeological units; they were distinguished mainly on the basis of pottery in the Neolithic, and of flints in the Mesolithic. So, in my view, an inconsistency occurs here: flints did not dema-terialize in the Neolithic period. Quite the contrary, flint working still flourished. Let us look then at the discussed period solely from a generalized flint perspective. The picture is different. First of all, we have early Neolithic industry that joins LBK and early post-LBK units (Fig. 8), which Bogdan Balcer calls 'mediolithic' (Balcer 1983; 1988). This kind of industry is based on medium-sized blades, with end-scrapers, truncations, and borers as main tools (Fig. 9). On the other hand, in point of fact, there is only one important late Mesolithic industry with a highly unified character, with just a few regional modifications (Fig. 8). It contains primarily trapezes, long truncations, end-scrapers and side-scrapers as the main tool types (Fig. 10). Actually Fig. 14. Macrolithic flint tools and cores of the TRB; after Balcer 1983. Fig. 15. Flint industry based on local raw materials from site of the TRB at Kawczyce (Little Poland, district Busko-Zdroj); after Nowak 1994. 150 Transformations in East-Central Europe from 6000 to 3000 BC> local vs. foreign patterns BC Fig. 16.

As to the Neolithic, the most important change took place in the middle of the fifth millennium BC as a result of contacts with Cucuteni-Trypole Culture (Fig. 12). Macrolithic industries, based on very long blades made of the best raw materials (Figs. 13, 14), appeared within later Lengyel-Polgar communities and this continued within the TRB (Budziszewski 2000; Balcer 1983; 1988; Maiecka-Kukawka 1992; Zako-scielna 1996; 2000). However, this type of industry did not amount to the entire TRB Culture. Northern groups used late Mesolithic flints, just like para-Neolithic and the last Mesolithic groups (Fig. 12) (Do-manska 1995; Jankowska 1990). To make the matter more complicated, we can discern a third type of flint manufacturing connected with some TRB groups. This industry is in a sense a little primitive. It is based mainly on local raw materials; it uses splintered technique very frequently, so the blade blanks are mostly small and irregular (Jankowska 1980; Nowak 1994; Swiderski, Wierzbicki 1995; Wierz-bicki 1992; 1999). I am not sure how we should label this kind of industry; the description 'based on local raw materials' seems to be the best solution at the moment. Conclusion 'Communicative communities' were units where information circulated without serious obstacles, and where the information package was accepted and understood consciously or even unconsciously. I think that in the period under discussion it is possible to discern at least four such units (Fig. 16). The first should be called Mesolithic. The second I would call 'foreign Neolithic'; it appeared in the mid-sixth millennium, then gained in significance a little, but in the fourth millennium it declined considerably. The third is 'local Neolithic', which for me embraces most of the TRB. In my view, this community was the main local response to earlier foreign impul- BC Fig. 17.

Importantly, this was not the only version of 'northern' Neolithisation; there was also an alternative form, the para-Neolithic. It was also a reaction to foreign influences, but of a different kind: para-Neolithic groups used elements that did not originate in Neolithic agro-pastoral communities, but in foraging, east European ones, which mentally were perhaps much closer to 'our' foragers. However, this picture does not correspond with the gene pools in the territories under discussion. Taking into account, inter alia, much less varied flint industries that I regard more resistant to the quick changes in fashion which are visible in pottery, I think that there were only two general genetic units (Fig. 17). From the very beginning of the Mesolithic, there existed a local gene pool. In the mid-sixth millennium, as a result of migration, a foreign one appeared, and grew in later periods, but never became predominant. In archaeological terms, this can be connected with the LBK, SBK, Lengyel-Polgar and with part of the TRB. To proceed one step further, let us consider the linguistic situation (Fig. 18). The linguistic variety did not exactly mirror the genetic variety, i.e. the two basic gene pools. If we accept Marek Zvelebil's hypothesis about Creolisation (Zvelebil 1995), the range of influence of foreign languages must have been greater than the extent of the foreign gene pool. Strictly speaking, I would perceive the majority of TRB groups as affected by the Creolisation process. Finally, it must be underlined that the date of 3000 BC is not the absolute time limit for the existence of foraging people in Polish territories. Their existence BC Fig. 18.
