The Middle Neolithic is known to mark the westward expansion of Comb Ware and related cultures in North-Eastern Europe.
Mathieson et al. (2017 and 2018) had this to say about the Middle Neolithic in the Baltic:
At Zvejnieki in Latvia, using 17 newly reported individuals and additional data for 5 previously reported34 individuals, we observe a transition in hunter-gatherer-related ancestry that is opposite to that seen in Ukraine. We find that Mesolithic and Early Neolithic individuals (labelled ‘Latvia_HG’) associated with the Kunda and Narva cultures have ancestry that is intermediate between WHG (approximately 70%) and EHG (approximately 30%), consistent with previous reports34–36(Supplementary Table 3). We also detect a shift in ancestry between Early Neolithic individuals and those associated with the Middle Neolithic Comb Ware complex (labelled ‘Latvia_MN’), who have more EHG-related ancestry; we estimate that the ancestry of Latvia_MN individuals comprises 65% EHG-related ancestry, but two of the four individuals appear to be 100% EHG in principal component space (Fig. 1b).
Other samples and errors on Y-SNP calls
The truth is, this is another sample (Latvia_MN_dup.I4627.SG) from the same individual ZVEJ26.
There is another sample used for the analysis of ZVEJ26, with the same data as in Mathieson et al. (2018), i.e. better coverage, and Y-DNA R1b1a1a(xR1b1a1a2).
Most samples in the tables from Wang et al. (2018) seem to be classified correctly, as in previous papers, but for:
Blätterhöhle Cave sample from Lipson et al. (2017), wrongly classified (again) as R1b1a1a2a1a2a1b2 (I am surprised no R1b-autochtonous-continuity-fan rushed to proclaim something based on this);
Mal’ta 1 sample from Raghavan et al. (2013) as R1b1a1a2;
Iron Gates HG, Schela Cladovey from Gonzalez Fortes (2017) as R1b1a1a2;
Oase1 from Fu (2015) as N1c1a;
samples from Skoglund et al. (2017) from Africa also wrongly classified as R1b1a1a2 and subclades.
It seems therefore that the poor coverage / SNPs hit on autosomes is the key common factor here for these Y-SNP calls, and so it is in the Zvejnieki MN1 duplicated sample. Anyway, if all Y-SNP calls come from the same software applied to all data, and this is going to be used in future papers, this seems to be a great improvement compared to Narasimhan et al. (2018)…
EDIT (25 JUN 2018): I have been reviewing some more papers apart from Mathieson et al. (2018) and Olalde et al. (2018) to compare the reported haplogroups, and there seems to be many potential errors (or updated data, difficult to say sometimes, especially when the newly reported haplogroup is just one or two subclades below the reported one in ‘old’ papers), not only those listed above.
The sample accession number in the European Nucleotide Archive (ENA) is SAMEA45565168 (Latvia_MN1/ZVEJ26) (see here), in case anyone used to this kind of analysis wishes to repeat the Y-SNP calls on both samples.
EDIT (25 JUN 2018): Added that it is another sample with lesser coverage from the same ZVEJ26 individual.
As expected, the first Y-DNA haplogroup of a sample from the North Pontic region (apart from an indigenous European I2 subclade) during its domination by the Yamna culture is of haplogroup R1b-L23, and it is dated ca. 2890-2696 BC. More specifically, it is of Z2103 subclade, the main lineage found to date in Yamna samples. The site in question is Dereivka, “in the southern part of the middle Dnieper, at the boundary between the forest-steppe and the steppe zones”.
There is no data on this individual in the supplementary material – since Eneolithic Dereivka samples come from stored dental remains – , but the radiocarbon date (if correct) is unequivocal: the Yamna cultural-historical community dominated over that region at that precise time. Why would the authors name it just “Ukraine_Eneolithic”? They surely took the assessment of archaeologists, and there is no data on it, so I agree this is the safest name to use for a serious paper. This would not be the first sample apparently too early for a certain culture (e.g. Catacomb in this case) which ends up being nevertheless classified as such. And it is also not impossible that it represents another close Ukraine Eneolithic culture, since ancestral cultural groups did not have borders…
NOTE. Why, on the other hand, was the sample from Zvejnieki – classified as of Latvia_LN – assumed to correspond to “Corded Ware” (like the recent samples from Plinkaigalis242 or Gyvakarai1), when we don’t have data on their cultures either? No conspiracy here, just taking assessments from different archaeologists in charge of these samples: those attributed to “Corded Ware” have been equally judged solely by radiocarbon date, but, combining the known archaeological signs of herding in the region arriving around this time with the old belief (similar to the “Iberia is the origin of Bell Beaker peoples” meme) that “only the Corded Ware culture signals the arrival of herding in the Baltic”. This assumption has been contested recently by Furholt, in an anthropological model that is now mainstream, upheld also by Anthony.
We already know that, out of three previous West Yamna samples, one shows Anatolian Neolithic ancestry, the so-called “Yamna outlier”. We also know that one sample from Yamna in Bulgaria also shows Anatolian Neolithic ancestry, with a distinct ‘southern’ drift, clustering closely to East Bell Beaker samples, as we can still see in Mathieson et al. (2018), see below. So, two “outliers” (relative to East Yamna samples) out of four samples… Now a new, fifth sample from Ukraine is another “outlier”, coinciding with (and possibly somehow late to be a part of) the massive migration waves into Central Europe and the Balkans predicted long ago by academics and now confirmed with Genomics.
I think there are two good explanations right now for its ancestral components and position in PCA:
How many generations are needed for ancestral components and PCA clusters to change to that extent, in regions where only some patrilocal chiefs but indigenous populations remain, and the population probably admixed due to exogamy, back-migrations, and “resurge” events? Not many, obviously, as we see from the differences among the many Bell Beaker samples of R1b-L23 subclades from Olalde et al. (2018)…
b) That this sample shows the first genetic sign of the precise population that contributed to the formation of the Catacomb culture. Since it is a hotly debated topic where and how this culture actually formed to gradually replace the Yamna culture in the central region of the Pontic-Caspian steppe, this sample would be a good hint of how its population came to be.
This could then be not ‘just another West Yamna outlier’, but would actually show meaningful ‘resurge’ of Neolithic Ukraine ancestry in the Catacomb culture.
It could be meaningul to derive hypotheses, in the same way that the late Central European CWC sample from Esperstedt (of R1a-M417 subclade) shows recent exogamy directly from the (now more probably eastern part of the) steppe or steppe-forest, and thus implies great mobility among distant CWC groups. Although, given the BB samples with elevated steppe ancestry and close PCA cluster from Olalde et al. (2018), it could also just mean exogamy from a near-by region, around the Carpathian Basin where Yamna migrants settled…
How to know which is the case? We have to wait for more samples in the region. For the moment, the date seems too early for the known radiocarbon dating of most archaeological remains of the Catacomb Culture.
An important consequence of the addition of these “Yamna outliers” for the future of research on Indo-European migrations is that, especially if confirmed as just another West Yamna sample – with more, similar samples – , early Palaeo-Balkan peoples migrating south of the Danube and later through Anatolia may need to be judged not only in terms of ancestral components or PCA (as in the paper on Minoans and Mycenaeans), but also and more decisively using phylogeography, especially with the earliest samples potentially connected with such migrations.
Even without express confirmation of its presence in the steppe, the alternative model of a Balkan origin seems unlikely, given the almost certain continuity of expanding Yamna clans as East Bell Beaker ones, in this clearly massive and relatively quick expansion that did not leave much time for founder effects. But, of course, it is not impossible to think about a previously hidden R1b-L151 community in the Carpathian Basin yet to be discovered, adopting North-West Indo-European (by some sort of founder effect) brought there by Yamna peoples of exclusively R1b-Z2103 lineages. As it is not impossible to think about a hidden and ‘magically’ isolated community of haplogroup R1a-M417 in Yamna waiting to be discovered…Just not very likely, either option.
As to why this sample or the other Bell Beaker samples “solve” the question of R1a-Z645 subclades (typical of Corded Ware migrants) not expanding with Yamna, it’s very simple: it doesn’t. What should have settled that question – in previous papers, at least since 2015 – is the absence of this subclade in elite chiefs of clans expanded from Khvalynsk, Yamna, or their only known offshoots Afanasevo and Bell Beaker. Now we only have still more proof, and no single ‘outlier’ in that respect.
Not that radiocarbon dates or the actual origin of this sample cannot be wrong, mind you, it just strikes me how twisted such biased reasonings may be, depending on the specific sample at hand… Denial, anger, and bargaining, including shameless circular reasoning – we know the drill: we have seen it a hundred times already, with all kinds of supremacists autochthonous continuists who still today manage to place an oudated mythical symbolism on expanding Proto-Indo-Europeans, or on regional ethnolinguistic continuity…
Computing D-statistics for each individual of the form D(Baltic LN, Yamnaya; X, Mbuti), we find that the two individuals from the early phase of the LN (Plinkaigalis242 and Gyvakarai1, dating to ca. 3200–2600 calBCE) form a clade with Yamnaya (Supplementary Table 7), consistent with the absence of the farmer-associated component in ADMIXTURE (Fig. 2b). Younger individuals share more alleles with Anatolian and European farmers (Supplementary Table 7) as also observed in contemporaneous Central European CWC individuals2.
My interpretation of the Zvejnieki sample ca. 2880 BC (and thus also of the only Baltic LN sample forming a close cluster with it) as ‘outlier’ seems thus reinforced as more samples come in. My explanation based on exogamy is one possibility for the region. After all, great mobility and exogamy practices are universally accepted for the Corded Ware territory, and Yamna migrants had settled up along the Prut precisely around this period (ca. 3100-2900 BC), so this kind of relation between Yamna and Baltic samples is to be expected.
Plinkaigalis 242, >40 year old female (OxA-5936, 4280 ± 75 BP, 3260–2630 calBCE). The burial site is located in the plains of central Lithuania on the eastern bank of the river Šušvė on the outskirts of the Plinkaigalis village, approximately 400 m southeast of an Iron age hill fort and settlement. The burial site was discovered in 1975 when local residents started digging for gravel in the western part of the hill. The same year site was granted a legal protection with archaeological excavations carried out for eight straight years in a row (1977-1984). During the eight years of fieldwork a total of 373 graves (364 inhumation and 9 cremation graves) with all but two of them dating to 3rd to 8th c. AD were uncovered. The two exceptional graves (no. 241, 242) were uncovered in the northern part of the burial site and C14 dated to the Late Neolithic.
Gyvakarai 1, 35-40 year old male (Poz-61584, 4030 ± 30 BP, 2620–2470 calBCE). The burial site is located in the northern part of Lithuania on the steep gravelly bank (elevation up to 79 m a. s. l.) of the rivulet Žvikė, 500 m to the south from where, in the wet grassland valley, it meets the main stem river Pyvesa. The site was discovered in 2000 when local residents started digging for gravel in the central part of the gravelly bank. The same year rescue excavations were conducted in the surrounding area of the highly disturbed grave resulting in discovery of a single grave C14 dated to the Late Neolithic.
EDIT (16 FEB 2018): A commentator noted that Gyvakaray1 was also studied for Yersinia pestis, a disease which appears to have expanded first to the west from the steppe, and then to the east, so it is possible that its position in PCA related to Plinkaigalis242 shows a connection to late Yamna settlers or East Bell Beaker migrants.
NOTE: I haven’t had the time and patience to work with my virtual computer on the PCA of these new samples – my CPU is reaching everyday its limit and my fans work half the time – , so I don’t know exactly which of them is Plinkaigalis242 and which Gyvakarai1, I just made a wild guess (based on ADMIXTURE) that the earlier Plinkaigalis242 forms a common ‘outlier’ group with Zvejnieki; if they are reversed or otherwise wrong in the image, please correct me. It will be much appreciated.
If we take the most recent reliable radiocarbon analyses of material culture, and interpretations based on them of Corded Ware as a ‘complex’similar to Bell Beaker (accepted more and more by disparate academics such as Anthony or Klejn), it seems that the controversial ‘massive’ Corded Ware migration must have begun somehow later than previously thought, which leaves these early Baltic samples still less clearly part of the initial Corded Ware culture, and more as outliers waiting for a more precise cultural context among Late Neolithic changes in the region.
However, if traditional Uralicists are right in supposing a loose Neolithic community in the Forest Zone, and Kristiansen is right in supposing long-lasting contacts in the Dniester-Dnieper region, we might actually be seeing with these ‘outliers’ the first proof that Neolithic samples from the forest-steppe and Forest Zone of the 4th millenium – unrelated to the Corded Ware culture – clustered closely to Khvalynsk, Sredni Stog, or Yamna samples, which is compatible with Piezonka’s accounts of intercultural contacts.
Acceptance of the results of radiometric dating meant that the concept of the so called ‘A-Horizon’ also had to be reformulated. If we are dealing with such a phase at all, it is not a classic typological period that is defined by a uniform material culture inventory, but rather a set of types which show a wide distribution, but which are always integrated into a locally specific and thus regionally variable context.
The situation resembles that of the Bell Beakers, where a few supra-regional types are associated with local forms of ‘Begleitkeramik’ (i.e. pottery that accompanies Bell Beakers: Strahm 1995; Besse 1996).
The distribution data indicate that this set of forms (namely the A-Beaker, ‘A-Amphora’, and A-Battle Axe, as well as Herringbone-decorated Beakers) was to be found over much of Europe around 2700 BC, and that the currency of these forms was not short: they seem to have been used continuously during the Final Neolithic, perhaps even until 2000 BC (Fig. 3; Furholt 2004). Analysis of the radiometric and dendrochronological determinations also indicates that the A-Horizon is not the earliest Corded Ware phase. Instead, it appears to follow an apparent earlier phase in Poland during which Corded Ware pottery was in use from as early as 2900 BC (Furholt 2003; 2008a; Wödarczak 2006; Ullrich 2008).
Corded Ware and Yamna/Bell Beaker
While widening networks and a change in the mechanism of exchange appears to have contributed to the emergence of the Corded Ware archaeological phenomenon, and also the contemporaneous Yamnaya graves (Harrison & Heyd 2007) and the following Bell Beaker and Early Bronze Age phenomena, it remains to be seen exactly what factors contributed to the development of these systems. It may be that there were changes in subsistence practices, perhaps involving a rising importance of animal herding that subsequently required higher mobility (for a discussion see Dörfler & Müller 2008), but considering the obvious diversity in subsistence patterns present in different Corded Ware groups, such an explanation would seem appropriate for the transformation in some regions, but surely not for the eastern hunterfisher-gatherer groups of the Baltic (Bläuer & Kantanen 2013). Also, trade with amber and copper might have played its role, but there are so far no indications for a significant rise in quantity or reach of these two materials in connection with Corded Ware graves or settlements (Furholt 2003, 125–7).
The impacts of animal traction and the wagon are also to be taken into account, as they are present since 3400 BC (Mischka 2011) but does at least not play any visible role in Corded Ware burial rituals, very much in contrast to the previous periods (Johannsen & Laursen 2010). There is no evidence for horse riding, but the domesticated horse seems to be present in central Europe since before 3000 BC (Becker 1999) and have also been found in Corded Ware settlements (Becker 2008), but again the evidence of domesticated horses is much more abundant in the period before 3000 BC.
So, concerning amber and copper exchange, or the impact of the wheel and animal traction, there is the recurrent motive of stronger evidence for the period before 3000 BC than during or in connection to Corded Ware finds after 2700 BC.
The evidence strongly points towards a long period of coalescence from 3000 to 2700 BC, when several innovations in burial customs, pottery, and tool types sprung forth from different places and subsequently spread via different networks of exchange and interaction. These surely showed a significant rise in scale, reach, and impact on local practices, but the same is true for the contemporary Globular Amphora and Yamnaya ‘Cultures’. This exchange resulted, roughly spoken, in a phenomenon like the A-Horizon.
Thus, it seems reasonable to explain the wide regional reach of those Corded Ware elements as the result of a general increase in mobility and thus an increase in the spatial extension of regional networks, triggered by the long-term effects of technological innovations and connected economic and social transformations in Europe since 3400 BC. It is the increase in mobility and regional networks that is new to the European Neolithic Societies after this time, and it is not only the Corded Ware elements, that are spread through these channels but also Yamnaya, Globular Amphorae, Bell Beaker ‘Cultures’, and copper and bronze artefacts in later periods. Those are archaeological classification units, heuristic tools for the ordering of finds, while brushing over variability and overlapping traits, and so they should not be confused with real social groups.
Important excerpts for the Indo-European question (emphasis mine):
Mesolithic to Neolithic
In the archaeological understanding, the transition from Mesolithic to Neolithic in the Eastern Baltic region does not coincide with a large-scale population turnover and a stark shift in economy as seen in Central and Southern Europe. Rather, it is signified by a change in networks of contacts and the use of pottery, among other material, cultural and economic changes. Our results suggest continued admixture between groups in the south of the Eastern Baltic region, who are more closely related to WHG, and northern or eastern groups, more closely related to EHG. Neolithic social networks from the Eastern Baltic to the River Volga could also explain similarities of the hunter-gatherer pottery styles, although morphologically analogous ceramics might also have developed independently due to similar functionality. The genetic evidence for a change in networks and possibly even a large-scale population movement is most pronounced in the Middle Neolithic in individuals attributed to the CCC. The distribution of this culture overlaps in the north with the Narva culture and extends further north to Finland and Karelia. Its spread in the Eastern Baltic is linked with a significant change in imported raw materials, artefacts, and the appearance of village-like settlements15.
Neolithic to Chalcolithic
We see a further population movement into the regions surrounding the Baltic Sea with the CWC in the Late Neolithic that was accompanied by the first evidence of extensive animal husbandry in the Eastern Baltic. The presence of ancestry from the Pontic-Caspian Steppe among Baltic CWC individuals without the genetic component from north-western Anatolian Neolithic farmers must be due to a direct migration of steppe pastoralists that did not pick up this ancestry in Central Europe. It suggests import of the new economy by an incoming steppe-like population independent of the agricultural societies that were already established to the south and west of the Baltic Sea. The presence of direct contacts to the steppe could lend support to a linguistic model that sees an early branching of Balto-Slavic from a Proto-Indo-European language, for which the west Eurasian steppe was proposed as a homeland. However, as farmer ancestry is found in later Eastern Baltic individuals, it is likely that considerable individual mobility and a network of contact throughout the range of the CWC facilitated its spread eastward, possibly through exogamous marriage practices. Conversely, the appearance of mitochondrial haplogroup U4 in the Central European Late Neolithic after millennia of absence could indicate female gene-flow from the Eastern Baltic, where this haplogroup was present at high frequency.
There obviously was exogamy – which may in fact justify the findings in PCA close to Yamna (like the Zvejnieki sample), although researchers obviate that.
Also, as expected, no R1b-M269 in the Baltic (during the Corded Ware period), most are R1a with the majority showing subclade R1a-Z645 (and others poor SNP coverage), which support the reduction in haplogroup diversity to this very subclade during the expansion of Corded Ware peoples, as I predicted it would happen.
Local foraging societies were, however, not completely replaced and contributed a substantial proportion to the ancestry of Eastern Baltic individuals of the latest LN and Bronze Age. This ‘resurgence’ of hunter-gatherer ancestry in the local population through admixture between foraging and farming groups recalls the same phenomenon observed in the European Middle Neolithic and is responsible for the unique genetic signature of modern-day Eastern Baltic populations.
We suggest that the Siberian and East Asian related ancestry in Estonia, and Y-haplogroup N in north-eastern Europe, where it is widespread today, arrived there after the Bronze Age, ca. 500 calBCE, as we detect neither in our Bronze Age samples from Lithuania and Latvia. As Uralic speaking populations of the Volga-Ural region show high frequencies of haplogroup N, a connection was proposed with the spread of Uralic language speakers from the east that contributed to the male gene pool of Eastern Baltic populations and left linguistic descendants in the Finno-Ugric languages Finnish and Estonian. A potential future direction of research is the identification of the proximate population that contributed to the arrival of this eastern ancestry into Northern Europe.
It is funny to see how people keep trying to identify R1a with ‘Yamnaya’, now ‘steppe’, but always Indo-European (an ethnolinguistic term, mind you) supposedly because of the ‘Yamnaya’ (now ‘steppe’) admixture, but the only ‘mark’ of Uralic languages for the same researchers in the same paper using this very concept is nevertheless, paradoxically, haplogroup N, with an assumption explicitly based on prevalence in modern populations…
This admixture vs. haplogroup questionfor language and culture identification in genetic papers is really gettting messed up with new data, now in a contortionist-like way…

The following is a selection of articles I deem more interesting, but almost all are.
In the late 5th, 4th, and early 3rd millennia BC, different archaeological units are visible in western Lesser Poland. According to traditional views, local branches of the late Lengyel-Polgár complex, the Funnel Beaker culture, and the Baden phenomena overlap chronologically in great measure. The results of investigations done with new radiocarbon dating show that in some cases a discrete mode and linearity of cultural transformation is recommended. The study demonstrates that extreme approaches in which we either approve only those dates which fit with our concepts or accept with no reservation all dates as such are incorrect.
This article brings new data against David Anthony’s new IECWT model, suggesting later dates for the Corded Ware Culture group of Lesser Poland, and thus an earlier origin of their nomadic herders in the steppe, forest-steppe or forest zone to the east and south-east.
This paper presents an analysis of human and animal remains from Verteba cave, near Bilche Zolote, western Ukraine. This study was prompted by a paucity of direct dates on this material and the need to contextualise these remains in relation both to the transition from hunting and gathering to farming in Ukraine, and their specific place within the Cucuteni-Trypillia culture sequence. The new absolute dating places the remains studied here in Trypillia stages BII/CI at c. 3900–3500 cal BC, with one individual now redated to the Early Scythian period. As such, these finds are even more exceptional than previously assumed, being some of the earliest discovered for this culture. The isotope analyses indicate that these individuals are local to the region, with the dietary stable isotopes indicating a C3 terrestrial diet for the Trypillia-period humans analysed. The Scythian period individual has δ13C ratios indicative of either c. 50% marine, or alternatively C4 plant inputs into the diet, despite δ18O and 87Sr/86Sr ratios that are comparable to the other individuals studied.
The first ceramic complexes appeared in the forest-steppe and forest zones of Eastern Europe at the end of the 7th–5th millennium BC. They existed until the first half of the 5th millennium BC in the Don River basin. All these first ceramic traditions had common features and also local particularities. Regional cultures, distinguished nowadays on the basis of these local particularities, include the Karamyshevskaya and Middle Don cultures, as well pottery of a new type found at sites on the Middle Don River (Cherkasskaya 3 and Cherkasskaya 5 sites).
So far, four different cultural-chronological groups of sites have been identified in the North-eastern Azov Sea and Lower Don River areas, including sites of the Rakushechny Yar culture, Matveev Kurgan culture, Donets culture, and sites of the Caspian-Ciscaucasian region. An analysis of all known dates, as well as the contexts and stratigraphies of the sites, allowed us to form a new perspective of the chronology of southern Russia, to revise the chronology of this region, and change the concept of unreliability of dates for this area.
During excavations of burials at Zvejnieki in northern Latvia, it transpired that the grave fill included occupation material brought to the grave. It contained tools of a type that could not be contemporaneous with the grave. This is confirmed by the dating of bone tools and other bone finds in the fill. The fill was taken from an older settlement site a short distance away. The fill also included skeletal parts of humans whose graves had been destroyed with the digging of the grave for a double burial. This provides an interesting view of the mortuary practice of hunter-gatherers and an insight into the use of the past in the past.
I keep expecting that more information is given regarding the important sample labelled “Late Neolithic/Corded Ware Culture” from Zvejnieki ca. 2880 BC. It seems too early for the Corded Ware culture in the region, clusters too close to steppe samples, and the information on it from genetic papers is so scarce… My ad hoc explanation of these data – as a product of recent exogamy from Eastern Yamna -, while possibly enough to explain one sample, is not satisfying without further data, so we need to have more samples from the region to have a clearer picture of what happened there and when. Another possibility is a new classification of the sample, compatible with later migration events (a later date of the sample would explain a lot). Anyway, this article won’t reveal anything about this matter, but is interesting for other, earlier samples from the cemetery.
We present the results of a paleogenetic analysis of nine individuals from two Early Iron Age mounds in the Baraba forest -teppe, associated with the Sargat culture (ﬁ ve from Pogorelka-2 mound 8, and four from Vengerovo-6 mound 1). Four systems of genetic markers were analyzed: mitochondrial DNA, the polymorphic part of the amelogenin gene, autosomal STR-loci, and those of the Y-chromosome. Complete or partial data, obtained for eight of the nine individuals, were subjected to kinship analysis. No direct relatives of the “parent-child” type were detected. However, the data indicate close paternal and maternal kinship among certain individuals. This was evidently one of the reasons why certain individuals were buried under a single mound. Paternal kinship appears to have been of greater importance. The diversity of mtDNA and Y-chromosome lineages among individuals from one and the same mound suggests that kinship was not the only motive behind burying the deceased people jointly. The presence of very similar, though not identical, variants of the Y chromosome in different burial grounds may indicate the existence of groups such as clans, consisting of paternally related males. Our conclusions need further conﬁ rmation and detailed elaboration.
