Złota a GAC-CWC transitional group…but not the origin of Corded Ware peoples

Open access Unraveling ancestry, kinship, and violence in a Late Neolithic mass grave, by Schroeder et al. PNAS (2019).

Interesting excerpts of the paper and supplementary materials, about the Złota group variant of Globular Amphora (emphasis mine):

A special case is the so-called Złota group, which emerged around 2,900 BCE in the northern part of the Małopolska Upland and existed until 2,600-2,500 BCE. Originally defined as a separate archaeological “culture” (15), this group is mainly defined by the rather local introduction of a distinct form of burial in the area mentioned. Distinct Złota settlements have not yet been identified. Nonetheless, because of the character of its burial practices and material culture, which both retain many elements of the GAC and yet point forward to the Corded Ware tradition, and because of its geographical location, the Złota group has attracted significant archaeological attention (15, 16).

The Złota group buried their dead in a new, distinct type of funerary structure; so-called niche graves (also called catacomb graves). These structures featured an entrance shaft or pit and, below that, a more or less extensive niche, sometimes connected to the entrance area by a narrow corridor. Local limestone was used to seal off the entrance shaft and to pave the floor of the niche, on which the dead were usually placed along with grave goods. This specific and relatively sophisticated form of burial probably reflects contacts between the northern Małopolska Upland and the steppe and forest-steppe communities further to the east, who also buried their dead in a form of catacomb graves. Individual cases of the use of ochre and of deformation of skulls in Złota burials provide further indications of such a connection (15). At the same time, the Złota niche grave practice also retains central elements of the GAC funerary tradition, such as the frequent practice of multiple burials in one grave, often entailing redeposition and violation of the anatomical order of corpses, and thus differs from the catacomb grave customs found on the steppes which are strongly dominated by single graves. Nonetheless, at Złota group cemeteries single burial graves appear, and even in multiple burial graves the identity of each individual is increasingly emphasized, e.g. by careful deposition of the body and through the personal nature of grave goods (16).

Correspondence analysis of amphorae from the Złota-graveyards reveals that there is no typological break between Globular Amphorae and Corded Ware Amphorae, including ‘Strichbündelamphorae’ (after Furholt 2008)

Just like its burial practices, the material culture and grave goods of the Złota group combine elements of the GAC, such as amber ornaments and central parts of the ceramic inventory, with elements also found in the Corded Ware tradition, such as copper ornaments, stone shaft-hole axes, bone and shell ornaments, and other stylistic features of the ceramic inventory. In particular, Złota group ceramic styles have been seen as a clear transitional phenomenon between classical GAC styles and the subsequent Corded Ware ceramics, probably playing a key role in the development of the typical cord decoration patterns that came to define the latter (17).

As briefly summarized above, the Złota group displays a distinct funerary tradition and combination of material culture traits, which give the clear impression of a cultural “transitional situation”. While the group also appears to have had long-distance contacts directed elsewhere (e.g. to Baden communities to the south), it is the combination of Globular Amphora traits, on the one hand, and traits found among late Yamnaya or Catacomb Grave groups to the east as well as the closely related Corded Ware groups that emerged around 2,800 BCE, on the other hand, that is such a striking feature of the Złota group and which makes it interesting when attempting to understand cultural and demographic dynamics in Central and Eastern Europe during the early 3rd millennium BCE.

Książnice (site 2, grave 3ZC), Świętokrzyskie province. This burial, a so-called niche grave of the Złota type (with a vertical entrance shaft and perpendicularly situated niche), was excavated in 2006 and contained the remains of 8 individuals, osteologically identified as three adult females and five children, positioned on limestone pavement in the niche part of the grave. Radiocarbon dating of the human remains indicates that the grave dates to 2900-2630 BCE, 95.4% probability (Dataset S1). The grave had an oval entrance shaft with a diameter of 60 cm and depth of 130 cm; the depth of the niche reached to 170 cm (both measured from the modern surface), and it also contained a few animal bones, a few flint artefacts and four ceramic vessels typical of the Złota group. Książnice is located in the western part of the Małopolska Upland, which only has a few Złota group sites but a stronger presence of other, contemporary groups (including variants of the Baden culture).

Wilczyce (site 90, grave 10), Świętokrzyskie province. A rescue excavation in 2001 uncovered a niche grave of the Złota type, which had a round entrance shaft measuring 90 cm in diameter. The grave was some 60-65 cm deep below the modern surface and the bottom of the niche was paved with thin limestone plates, on which remains of three individuals had been placed; two adults, one female and one male, and one child. Four ceramic vessels of Złota group type were deposited in the niche along with the bodies. Wilczyce is located in the Sandomierz Upland, an area with substantial presence of both the Globular Amphora culture and Złota group, as well as the Corded Ware culture from 2800 BCE.

Image modified to outline in red GAC and Złota groups.

To further investigate the ancestry of the Globular Amphora individuals, we performed a supervised ADMIXTURE (6) analysis, specifying typical western European hunter-gatherers (Loschbour), early Neolithic Anatolian farmers (Barcın), and early Bronze Age steppe populations (Yamnaya) as ancestral source populations (Fig. 2B). The results indicate that the Globular Amphora/Złota group individuals harbor ca. 30% western hunter-gatherer and 70% Neolithic farmer ancestry, but lack steppe ancestry. To formally test different admixture models and estimate mixture proportions, we then used qpAdm (7) and find that the Polish Globular Amphora/Złota group individuals can be modeled as a mix of western European hunter-gatherer (17%) and Anatolian Neolithic farmer (83%) ancestry (SI Appendix, Table S2), mirroring the results of previous studies.

zlota-steppe-ancestry-cwc
Table S2. qpADM results. The ancestry of most Globular Amphora/Złota group individuals
can be modelled as a two-way mixture of Mesolithic western hunter-gatherers (WHG), and early Anatolian Neolithic farmers (Barcın). The five individuals from Książnice (Złota group) show evidence for additional gene flow, most likely from an eastern source.

The lack of a direct genetic connection of Corded Ware peoples with the Złota group despite their common “steppe-like traits” – shared with Yamna – reveals, once more, how the few “Yamna-like” traits of Corded Ware do not support a direct connection with Indo-Europeans, and are the result of the expansion of the so-called steppe package all over Europe, and particularly among cultures closely related to the Khvalynsk expansion, and later under the influence of expanding Yamna peoples.

The results from Książnice may support that early Corded Ware peoples were in close contact with GAC peoples in Lesser Poland during the complex period of GAC-Trypillia-CWC interactions, and especially close to the Złota group at the beginning of the 3rd millennium BC. Nevertheless, patrilineal clans of Złota apparently correspond to Globular Amphorae populations, with the only male sample available yet being within haplogroup I2a-L801, prevalent in GAC.

NOTE. The ADMIXTURE of Złota samples in common with GAC samples (and in contrast with the shared Sredni Stog – Corded Ware “steppe ancestry”) makes the possibility of R1a-M417 popping up in the Złota group from now on highly unlikely. If it happened, that would complicate further the available picture of unusually diverse patrilineal clans found among Uralic speakers expanding with early Corded Ware groups, in contrast with the strict patrilineal and patrilocal culture of Indo-Europeans as found in Repin, Yamna and Bell Beakers.

Once again the traditional links between groups hypothesized by archaeologists – like Gimbutas and Kristiansen in this case – are wrong, as is the still fashionable trend in descriptive archaeology, of supporting 1) wide cultural relationships in spite of clear-cut inter-cultural differences (and intra-cultural uniformity kept over long distances by genetically-related groups), 2) peaceful interactions among groups based on few common traits, and 3) regional population continuities despite cultural change. These generalized ideas made some propose a steppe language shared between Pontic-Caspian groups, most of which have been proven to be radically different in culture and genetics.

Furthermore, paternal lines show once again marked bottlenecks in expanding Neolithic cultures, supporting their relevance to follow the ethnolinguistic identity of different cultural groups. The steppe- or EHG-related ancestry (if it is in fact from early Corded Ware peoples) in Książnice was thus probably, as in the case of Trypillia, in the form of exogamy with females of neighbouring groups:

The presence of unrelated females and related males in the grave is interesting because it suggests that the community at Koszyce was organized along patrilineal lines of descent, adding to the mounting evidence that this was the dominant form of social organization among Late Neolithic communities in Central Europe. Usually, patrilineal forms of social organization go hand in hand with female exogamy (i.e., the practice of women marrying outside their social group). Indeed, several studies (11, 12) have shown that patrilocal residence patterns and female exogamy prevailed in several parts of Central Europe during the Late Neolithic. (…) the high diversity of mtDNA lineages, combined with the presence of only a single Y chromosome lineage, is certainly consistent with a patrilocal residence system.

Since ancient and modern Uralians show predominantly Corded Ware ancestry, and Proto-Uralic must have been in close contact with Proto-Indo-European for a very long time – given the different layers of influence that can be distinguished between them -, it follows as logical consequence that the North Pontic forest-steppes (immediately to the west of the PIE homeland in the Don-Volga-Ural steppes) is the most likely candidate for the expansion of Proto-Uralic, accompanying the spread of Sredni Stog ancestry and a bottleneck under R1a-M417 lineages.

The early TMRCAs in the 4th millennium BC for R1a-M417 and R1a-Z645 support this interpretation, like the R1a-M417 sample found in Sredni Stog. On the other hand, the resurgence of typical GAC-like ancestry in late Corded Ware groups, with GAC lineages showing late TMRCAs in the 3rd millennium BC, proves the disintegration of Corded Ware all over Europe (except in Textile Ceramics- and Abashevo-related groups) as the culture lost its cohesion and different local patrilineal clans used the opportunity to seize power – similar to how eventually I2a-L621 infiltrated eastern (Finno-Ugrian) groups.

Resurge of local populations in the final Corded Ware culture period from Poland

poland-kujawy

Open access A genomic Neolithic time transect of hunter-farmer admixture in central Poland, by Fernandes et al. Scientific Reports (2018).

Interesting excerpts (emphasis mine, stylistic changes):

Most mtDNA lineages found are characteristic of the early Neolithic farmers in south-eastern and central Europe of the Starčevo-Kőrös-Criş and LBK cultures. Haplogroups N1a, T2, J, K, and V, which are found in the Neolithic BKG, TRB, GAC and Early Bronze Age samples, are part of the mitochondrial ‘Neolithic package’ (which also includes haplogroups HV, V, and W) that was introduced to Europe with farmers migrating from Anatolia at the onset of the Neolithic17,31.

A noteworthy proportion of Mesolithic haplogroup U5 is also found among the individuals of the current study. The proportion of haplogroup U5 already present in the earliest of the analysed Neolithic groups from the examined area differs from the expected pattern of diversity of mtDNA lineages based on a previous archaeological view and on the aDNA findings from the neighbouring regions which were settled by post-Linear farmers similar to BKG at that time. A large proportion of Mesolithic haplogroups in late-Danubian farmers in Kuyavia was also shown in previous studies concerning BKG samples based on mtDNA only, although these frequencies were derived on the basis of very small sample sizes.

y-dna-poland

A significant genetic influence of HG populations persisted in this region at least until the Eneolithic/Early Bronze Age period, when steppe migrants arrived to central Europe. The presence of two outliers from the middle and late phases of the BKG in Kuyavia associated with typical Neolithic burial contexts provides evidence that hunter-farmer contacts were not restricted to the final period of this culture and were marked by various episodes of interaction between two societies with distinct cultural and subsistence differences.

The identification of both mitochondrial and Y-chromosome haplogroup lineages of Mesolithic provenance (U5 and I, respectively) in the BKG support the theory that both male and female hunter-gatherers became part of these Neolithic agricultural societies, as has been reported for similar cases from the Carpathian Basin, and the Balkans. The identification of an individual with WHG affinity, dated to ca. 4300 BCE, in a Middle Neolithic context within a BKG settlement, provides direct evidence for the regional existence of HG enclaves that persisted and coexisted at least for over 1000 years, from the arrival of the LBK farmers ca. 5400 BCE until ca. 4300 BCE, in proximity with Neolithic settlements, but without admixing with their inhabitants.

Principal component analysis with modern populations greyed out on the background (top), ADMIXTURE results with K = 10 with samples from this study amplified (bottom).

The analysis of two Late Neolithic cultures, the GAC and CWC, shows that steppe ancestry was present only among the CWC individuals analysed, and that the single GAC individual had more WHG ancestry than previous local Neolithic individuals. (…) The CWC’s affinity to WHG, however, contrasts with results from published CWC individuals that identified steppe ancestry related to Yamnaya as the major contributor to the CWC genomes, while here we report also substantial contributions from WHG that could relate to the late persistence of pockets of WHG populations, as supported by the admixture results of N42 and the finding of the 4300-year-old N22 HG individual. These results agree with archaeological theories that suggest that the CWC interaction with incoming steppe cultures was complex and that it varied by region.

Some comments

About the analyzed CWC samples, it is remarkable that, even though they are somehow related to each other, they do not form a tight cluster. Also, their Y-DNA (I2a), and this:

When compared to previously published CWC data, our CWC group (not individuals) is genetically significantly closer to WHG than to steppe individuals (Z = −4.898), a result which is in contrast with those for CWC from Germany (Z = 2.336), Estonia (Z = 0.555), and Latvia (Z = 1.553).

Włodarczak (2017) talks about the CWC period in Poland after ca. 2600 BC as a time of emergence of an allochthnous population, marked by the rare graves of this area, showing infiltrations initially mainly from Lesser Poland, and later (after 2500 BC) from the western Baltic zone.

Since forest sub-Neolithic populations would have probably given more EHG to the typical CWC population, these samples support the resurge of ‘local’ pockets of GAC- or TRB-like groups with more WHG (and also Levant_Neolithic) ancestry.

The known presence of I2a2a1b lineages in GAC groups in Poland also supports this interpretation, and the subsistence of such pockets of pre-steppe-like populations is also seen with the same or similar lineages appearing in comparable ‘resurge’ events in Central Europe, e.g. in samples from the Únětice and Tumulus culture.

About the Bronze Age sample, we have at last official confirmation of haplogroup R1a1a (sadly no subclade*) at the very beginning of the Trzciniec period – in a region between western (Iwno) and eastern (Strzyżów) groups related to Mierzanowice – , which has to be put in relation with the samples from the final Trzciniec period in the Baltic published in Mittnik et al. (2018).

EDIT (8 OCT 2018): More specific subclades have been published, including a R1a-Z280 lineage for the Bronze Age sample (see spreadsheet).

This confirms the early resurge of R1a-Z645 (probably R1a-Z282) lineages at the core of the developing East European Bronze Age, a province of the European Bronze Age that emerged from evolving Bell Beaker groups in Poland.

I don’t have any hope that the Balto-Slavic evolution through BBC Poland → Mierzanowice/Iwno → Trzciniec → Lusatian cultures is going to be confirmed any time soon, until we have a complete trail of samples to follow all the way to historic Slavs of the Prague culture. However, I do think that the current data on central-east Europe – and the recent data we are receiving from north-east Europe and the Iranian steppes, at odds with the Indo-Slavonic alternative – supports this model.

I guess that, in the end, similar to how the Yamna vs. Corded Ware question is being solved, the real route of expansion of Proto-Balto-Slavic (supposedly spoken ca. 1500-1000 BC) is probably going to be decided by the expansion of either R1a-M458 (from the west) or R1a-Z280 lineages (from the east), because the limited precision of genetic data and analyses available today are going to show ‘modern Slavic’-like populations from the whole eastern half of Europe for the past 4,000 years…

On the origin and spread of haplogroup R1a-Z645 from eastern Europe

indo-european-uralic-migrations-corded-ware

In my recent post about the origin and expansion of haplogroup R1b-L51, Chetan made an interesting comment on the origin and expansion of R1a-Z645. Since this haplogroup is also relevant for European history and dialectal North-West Indo-European and Indo-Iranian expansion, I feel compelled to do a similar post, although the picture right now is more blurry than that of R1b-L51.

I find it interesting that many geneticists would question the simplistic approach to the Out of Africa model as it is often enunciated, but they would at the same time consider the current simplistic model of Yamna expansion essentially right; a model – if anyone is lost here – based on proportions of the so-called Yamnaya™ ancestral component, as found in a small number of samples, from four or five Eneolithic–Chalcolithic cultures spanning more than a thousand years.

The “75% Yamnaya ancestry of Corded Ware”, which has been given so much publicity since 2015, made geneticists propose a “Yamna → Corded Ware → Únětice / Bell Beaker” migration model, in order of decreasing Yamnaya proportions. Y-DNA and solid archaeological models suggested that this model was wrong, and recent findings have proven it was. In fact, the CWC sample closest to Yamna was a late outlier of Esperstedt in Central Europe, whose ancestry is most likely directly related to Yamna settlers from Hungary.

These wrong interpretations have been now substituted by data from two new early samples from the Baltic, which cluster closely to Yamna, and which – based on the Y-DNA and PCA cluster formed by all Corded Ware samples – are likely the product of female exogamy with Yamna peoples from the neighbouring North Pontic region (as we are seeing, e.g. in the recent Nikitin et al. 2018).

NOTE. There is also another paper from Nikitin et al. (2017), with more ancient mtDNA, “Subdivisions of haplogroups U and C encompass mitochondrial DNA lineages of Eneolithic-Early Bronze Age Kurgan populations of western North Pontic steppe”. Link to paper (behind paywall). Most interesting data is summarized in the following table:

yamna-corded-ware-mtdna

Even after the publication of Olalde et al. (2018) and Wang et al. (2018) – where expanding Yamna settlers and Bell Beakers are clearly seen highly admixed within a few generations, and are found spread across a wide Eurasian cline (sharing one common invariable trait, the paternally inherited haplogroup, as supported by David Reich) – fine-scale studies of population structure and social dynamics is still not a thing for many, even though it receives more and more advocates among geneticists (e.g. Lazaridis, or Veeramah).

NOTE. I have tried to explain, more than once, that the nature and origin of the so-called “Yamnaya ancestry” (then “steppe ancestry”, and now subdivided further as Steppe_EMBA and Steppe_MLBA) is not known with precision before Yamna samples of ca. 3000 BC, and especially that it is not necessarily a marker of Indo-European speakers. Why some people are adamant that steppe ancestry and thus R1a must be Indo-European is mostly related to a combination of grandaddy’s haplogroup, the own modern ethnolinguistic attribution, and an aversion to sharing grandpa with other peoples and cultures.

In the meantime, we are seeing the “Yamnaya proportion” question often reversed: “how do we make Corded Ware stem from Yamna, now that we believed it?”. This is a funny circular reasoning, akin to the one used by proponents of the Franco-Cantabrian origin of R1b, when they look now at EEF proportions in Iberian R1b-L23 samples. It seems too comic to be true.

R1a and steppe ancestry

The most likely origin of haplogroup R1a-Z645 is to be found in eastern Europe. Samples published in the last year support this region as a sort of cradle of R1a expansions:

  • I1819, Y-DNA R1a1-M459, mtDNA U5b2, Ukraine Mesolithic ca. 8825-8561 calBCE, from Vasilievka.
  • I5876, Y-DNA R1a, mtDNA U5a2a, Ukraine Mesolithic 7040-6703 calBCE, from Dereivka.
  • I0061, hg R1a1-M459 (xR1a1a-M17), mtDNA C1, ca. 6773-6000 calBCE (with variable dates), from Yuzhnyy Oleni Ostrov in Karelia.
  • Samples LOK_1980.006 and LOK_1981.024.01, of hg MR1a1a-M17, mtDNA F, Baikalic cultures, dated ca. 5500-5000 BC.
  • Sample I0433, hg R1a1-M459(xM198), mtDNA U5a1i, from Samara Eneolithic, ca. 5200-4000 BCE
  • Samples A3, A8, A9, of hg R1a1-M459, mtDNA H, from sub-Neolithic cultures (Comb Ware and Zhizhitskaya) at Serteyea, although dates (ca. 5th-3rd millennium BC) need possibly a revision (from Chekunova 2014).

NOTE. The fact that Europe is better sampled than North Asia, coupled with the finding of R1a-M17 in Baikalic cultures, poses some problems as to the precise origin of this haplogroup and its subclades. While the first (Palaeolithic or Mesolithic) expansion was almost certainly from Northern Eurasia to the west – due to the Mal’ta sample – , it is still unknown if the different subclades of R1a in Europe are the result of local developments, or rather different east—west migrations through North Eurasia.

Y-Full average estimates pointed to R1a-M417 formation ca. 6500 BC, TMRCA ca. 3500 BC, and R1a-Z645 formation ca. 3300 BC, TMRCA ca. 2900 BC, so the most likely explanation was that R1a-Z645 and its subclades – similar to R1b-L23 subclades, but slightly later) expanded quickly with the expansion of Corded Ware groups.

The presence of steppe ancestry in Ukraine Eneolithic sample I6561, of haplogroup R1a-M417, from Alexandria, dated ca. 4045-3974 calBCE, pointed to the forest steppe area and late Sredni Stog as the most likely territory from where the haplogroup related to the Corded Ware culture expanded.

However, the more recent Y-SNP call showing R1a-Z93 (L657) subclade rendered Y-Full’s (at least formation) estimates too young, so we have to rethink the actual origin of both subclades, R1a-Z93 (formation ca. 2900 BC, TMRCA ca 2700 BC), and R1a-Z283 (formation ca. 2900 BC, TMRCA ca. 2800 BC).

Contrary to what we thought before this, then, it is possible that the expansion of Khvalynsk-Novodanilovka chieftains through the steppes, around the mid-5th millennium BC, had something to do with the expansion of R1a-Z645 to the north, in the forest steppe.

We could think that the finding of Z93 in Alexandria after the expansion of Khvalynsk-Novodanilovka chiefs would make it more likely that R1a-Z645 will be found in the North Pontic area. However, given that Lower Mikhailovka and Kvitjana seem to follow a steppe-related cultural tradition, different to forest steppe cultures (like Dereivka and Alexandria), and that forest steppe cultures show connections to neighbouring northern and western forest regions, the rest of the expanding R1a-Z645 community may not be related directly to the steppe at all.

Adding a hypothetical split and expansion of Z645 subclades to the mid-/late-5th millennium could place the expansion of this haplogroup to the north and west, pushed by expanding Middle PIE-speaking steppe peoples from the east:

The Złota culture

I have already written about the Podolia-Volhynia region: about the North Pontic steppe cultures in contact with this area, and about the chaotic period of migrations when Corded Ware seem to have first emerged there among multi-directional and multi-ethnic migrants.

This is what Włodarczak (2017) says about the emergence of Corded Ware with ‘steppe features’ after the previous expansion of such features in Central Europe with Globular Amphorae peoples. He refers here to the Złota culture (appearing ca. 2900-2800 BC) in Lesser Poland, believed to be the (or a) transitional stage between GAC and Corded Ware, before the emergence of the full-fledged “Corded Ware package”.

So far, to the north of the Carpathian Mountains, including Polish lands, no graves indicating their relationship with communities of the steppe zone have been found. On the contrary, the funeral rites always display a local, central European nature. However, individual elements typical of steppe communities do appear, such as the “frog-like” arrangement of the body (Fig. 20), or items associated with Pit Grave milieux (cf. Klochko, Kośko 2009; Włodarczak 2014). A spectacular example of the latter is the pointed-base vessel of Pit Grave culture found at the cemetery in Święte, site 11 near Jarosław (Kośko et al. 2012). These finds constitute a confirmation of the importance of the relationships between communities of Pit Grave culture and Corded Ware culture. They are chronologically diverse, although most of them are dated to 2600-2400 BC – that is, to the “classic” period of Corded Ware culture.

funnelbeaker-trypillia-corded-ware
Map of territorial ranges of Funnel Beaker Culture (and its settlement concentrations in Lesser Poland), local Trypillian groups and early Corded Ware Culture settlements (◼) at the turn of the 4th/3rd millennia BC.

However, when discussing the relationships with the steppe communities, Polish lands deserve particular attention since part of the groups inhabiting it belonged to the eastern province of Corded Ware culture (cf. Häusler 2014), which neighboured Pit Grave culture both from the east and south. In addition, there was a tradition of varied relationships with the north Pontic zone, which began to intensify from the second half of the 4th millennium BC (Kośko, Szmyt, 2009; Kośko, Klochko, 2009). These connections are especially readable in Małopolska and Kujawy (Kośko 2014; Włodarczak 2014). The emergence of the community of Globular Amphora culture in the north Pontic zone at the end of the 4th and the beginnings of the 3rd millennium BC (Szmyt 1999) became a harbinger of a cultural closening between the worlds of central Europe and the steppe.

The second important factor taking place at that time was the expansion of the people of Pit Grave culture in a westerly direction, along the Danube thoroughfare. As a result of this, also to the south of the Carpathian Mountains, e.g., along the upper Tisza River, a new “kurgan” cultural system was formed. As one outcome, the areas of central Europe, above all Małopolska, found themselves in the vicinity of areas inhabited by communities characterized by new principles of social organization and a new funeral rite. Around 2800 BC these changes became evident in different regions of Poland, with the most numerous examples being documented in south-eastern Poland and Kujawy. The nature of the funeral rite and the features of the material culture perceptible at that time do not have straight forward analogies in the world of north Pontic communities. In this respect, the “A-horizon” is a phenomenon of local, central European origin. The events preceding the emergence of the said horizon (that is, the expansion of the people of Pit Grave culture into the area north of the arc of the Carpathians) are nowadays completely unidentifiable and remain merely an interesting theoretical matter (cf. e.g., Kośko 2000). Therefore, analysis of the archaeological sources cannot confirm the first archaeogenetic analysis suggesting a bond between the communities of the Pit Grave culture and Corded Ware culture (e.g., Haak et al. 2015).

Artefacts of the “A-horizon”, i.e., shaft-hole axes, amphorae (Fig. 21), beakers, and pots with a plastic wavy strip (Fig. 7) are found in different funerary and settlement contexts, sometimes jointly with finds having characteristics of various cultures (e.g., in graves of Złota culture, or at settlements of Rzucewo culture). Hence, they primarily represent a chronological phase (c. 2800-2600 BC), one obviously related to the expansion of a new ideology.

Eastern CWC expansion

Before continuing tracing the Corded Ware culture’s main features, it is worth it to trace first their movement forward in time, as Corded Ware settlers, from Poland to the east.

Circum-Baltic CWC

According to Klochko and Kośko (1998):

The colonizing Neolithic waves are continued by the Circum-Baltic Corded Ware culture, closely related to the traditions of the Single Grave culture and traditions of the Northern European Lowlands. After ca. 2900 BC, certain cultural systems with ‘corded’ traits –genetically related to the catchment area of the south-western Baltic – appear in the drainages of the Nemen, Dvina, Upper Dnieper, and even the Volga. These communities are considered the vector of Neolithisation in the Forest Zone.

The picture in the Baltic (Pamariu / Rzucewo) and Finland (Battle Axe) is thus more or less clearly connected with early dates ca. 2900-2800 BC:

There is a clear interaction sphere between the eastern Gulf of Finland area – reaching from Estonia to the areas of present-day Finland and the Karelian Isthmus in Russia –, evidenced e.g. by the sharp-butted axes, derived from the Estonian Karlova axe.

Interesting in this regard is the expansion of the Corded Ware culture in Finland, into a far greater territory than previously thought, that is poorly represented in most maps depicting the extent of the culture in Europe. Here is summary of CWC findings in Finland, using images from Nordqvist and Häkäla (2014):

Middle Dnieper and Fatyanovo

The earliest Middle Dnieper remains are related to CWC graves between the Upper Vistula and the Bug, containing pottery with Middle Dnieper traits, dated probably ca. 2700 BC, which links it with the expansion of the A-horizon. In fact, during the period ca. 2800-2400 BC, the area of Lesser Poland (with its numerous kurgans and catacomb burials) is considered the western fringe of an area spreading to the east, to the middle Dniester and middle Dnieper river basins, i.e. regions bordering the steppe oecumene. This ‘eastern connection’ of funeral ritual, raw materials, and stylistic traits of artefacts is also identified in some graves of the Polish Lowlands (Włodarczak 2017).

From Szmyt (2010)

The Fatyanovo (or Fatyanovo-Balanovo) culture was the easternmost group of the Corded Ware culture, and occupied the centre of the Russian Plain, from Lake Ilmen and the Upper Dnieper drainage to the Wiatka River and the middle course of the Volga. From the few available dates, the oldest ones from the plains of the Moskva river, and from the late Volosovo culture containing also Fatyanovo materials, and in combination they show a date of ca. 2700 BC for its appearance in the region. The Volosovo culture of foragers eventually disappeared when the Fatyanovo culture expanded into the Upper and Middle Volga basin.

The origin of the culture is complicated, because it involves at its earliest stage different Corded Ware influences in neighbouring sites, at least on the Moskva river plains (Krenke et al. 2013): some materials (possibly earlier) show Circum-Baltic and Polish features; other sites show a connection to western materials, in turn a bridge to the Middle Dnieper culture. This suggests that groups belonging to different groups of the corded ware tradition penetrated the Moscow region.

The split of subclades Z93 – Z283

If we take into account that the split between R1-Z93 and R1a-Z283 must have happened during the 5th millennium BC, we have R1a-Z93 likely around the middle Dnieper area (as supported by the Alexandria sample), and R1a-Z283 possibly to the north(-west), so that it could have expanded easily into Central Europe, and – through the northern, Baltic region – to the east.

Where exactly lies the division is unclear, but for the moment all reported Circum-Baltic samples with Z645 subclades seem to belong to Z282, while R1a samples from Sintashta/Potapovka (including the Poltavka outlier) point to Abashevo being dominated by R1a-Z93 subclades.

We have to assume, then, that an original east-west split betwen R1a-Z283 and R1a-Z93 turned, in the eastern migrations, into a north-south split between Z282 and Z93, where Finland and Battle Axe in general is going to show Z282, and Middle Dnieper – Abashevo Z93 subclades.

copper-age-early-cwc
Early Copper Age migrations ca. 3100-2600 BC.

I can think of two reasons why this is important:

  1. Depending on how Proto-Corded Ware peoples expanded, we may be talking about one community overcoming the other and imposing its language. Because either
    • clans of both Z93 and Z283 were quite close and kept intense cultural contacts around Dnieper-Dniester area; or
    • if the split is as early as the 5th millennium BC, and both communities separated then without contact, we are probably going to see a difference in the language spoken by both of them.
  2. In any case, the main north-south division of eastern Corded Ware groups is pointing to an important linguistic division within the Uralic-speaking communities, specifically between a Pre-Finno-Ugric and a Pre-Samoyedic one, and potentially between Pre-Finno-Permic and Pre-Ugric.

These may seem irrelevant questions – especially for people interested only in Indo-European migrations. However, for those interested in the history of Eurasian peoples and languages as a whole, they are relevant: even those who support an ‘eastern’ origin of Proto-Uralic, like Häkkinen, or Parpola (who are, by the way, in the minority, because most Uralicists would point to eastern Europe well before the Yamna expansion), place the Finno-Ugric expansion with the Netted Ware culture as the latest possible Finno-Ugric immigrants in Fennoscandia.

The Netted Ware culture

The image below shows the approximate expansion of Corded Ware peoples of Battle Axe traditions in Finland, as well as neighbouring Fennoscandian territories, from ca. 2800 BC until the end of the 3rd millennium. A controversial 2nd (late) wave of the so-called Estonian Corded Ware is popular in texts about this region, but has not been substantiated, and it seems to be a regional development, rather than the product of migrations.

Mapped (black dots) are finds of typical stone battle axes, used as a proxy (data from [8]). The red isolines indicate average permanent snow cover period from 1981 to 2010 (data from [9]). A recent study estimates the snow cover period ca 4500 years ago would have been 40–50 days less than today [10]. Overlying coloration refers to the lactose persistance (LP) allele gradient in modern northeastern Europe (see the electronic supplementary material, appendix B: Material and methods and table 1, for details); lozenge dots specify the dataset mean points for the triangulation. From Cramp et al. (2014).

As we have seen, Fatyanovo represents the most likely cultural border zone between Circum-Baltic peoples reaching from the Russian Battle Axe to the south, and Middle Dnieper peoples reaching from Abashevo to the north. In that sense, it also represents the most likely border culture between north-western (mainly R1a-Z282) and south-eastern (R1a-Z93) subclades.

With worsening climatic conditions (cooler seasons) at the end of the 3rd millennium, less settlements are apparent in the archaeological record in Finland. After ca. 2000 BC, two CWC-related cultures remain: in the coast, the Kiukainen culture, derived from the original Circum-Baltic Corded Ware settlers, reverts to a subsistence economy which includes hunting and fishing, and keeps mainly settlements (from the best territories) along the coast. In the inland, Netted Ware immigrants eventually appear from the south.

discussed here alongside actual sherds sampled and typical vessel forms (after [26–28]) (latter not shown to scale). Distribution maps show the geographical range of (f) Typical Comb Ware, (g) Corded Ware, (h) Kiukainen Ware and (i) Bronze Age cultures in the region (after [10,20,29]).”

The Netted Ware culture emerged in the Upper Volga–Oka region, derived from the Abashevo culture and its interaction with the Seima-Turbino network, and spread ca. 1900-1800 BC to the north into Finland, spreading into eastern regions previously occupied by cultures producing asbestos and organic-tempered wares (Parpola 2018).

NOTE. Those ‘contaminated’ by the Copenhagen fantasy map series may think that Volosovo hunter-gatherers somehow survived the expansion of Fatyanovo-Balanovo and Abashevo, hidden for hundreds of years in the forest, and then reappeared and expanded the Netted Ware culture. Well, they didn’t. At least not in archaeological terms, and certainly not with the genetic data we have.

If we combine all this information, and we think about these peoples in terms of Pre-Finno-Permic and Pre-Ugric languages developing side by side, we get a really interesting picture (see here for Proto-Fennic estimates):

  • The Battle Axe around the Baltic Sea – including the Gulf of Finland and Scandinavia – would be the area of expansion of Pre-Finno-Permic peoples, of R1a-Z283 subclades, which became later concentrated mainly on coastal regions;
  • the southern areas may correspond to Pre-Ugric peoples, which expanded later to the north with Netted Ware (see image below) – their precise subclades may be dependent on what will be found in Fatyanovo;
  • and Pre-Samoyedic peoples (of R1a-Z93 subclades) would have become isolated somewhere in the Cis- or (more likely) Trans-Urals region after 2000 BC, possibly from the interaction of the latest Balanovo stages and the Seima-Turbino phenomenon.

These communities in contact would have allowed for:

  • the known Indo-Iranian loanwords in Finno-Ugric to spread through a continuum of early dialects formed by Abashevo – Fatyanovo – Battle Axe groups;
  • the Finno-Saamic substrate of Germanic to be associated with Battle Axe groups in Scandinavia;
  • the important Palaeo-Germanic loanwords in Finno-Saamic spreading with long-term contacts (from Pre-Germanic to the Proto-Germanic, and later North Germanic period) through the Baltic Sea, between Scandinavia and the Gulf of Finland;
  • and Tocharian contacts with Samoyedic (although limited, and in part controversial), which point to its early expansion to the east of the Ural Mountains.

On the other hand, if one is inclined to believe that R1a and steppe ancestry do represent Indo-European speakers… which language was spoken from the Gulf of Finland well into the north, the inland, and Karelia, and in Northern Russia, by Corded Ware peoples and their cultural heirs (like Kiukainen or Netted Ware) for almost three thousand years?

Because we know that no other peoples of different haplogroups dominated over eastern Fennoscandia until the Iron Age, and N1c and Siberian ancestry expanded separately, and probably due to late bottlenecks, especially with Fennic peoples expanding recently to the north at the expense of the Saami population.

After the expansion of Bell Beaker peoples, the geographic distribution of late Corded Ware groups in the second half of the 3rd millennium, just before their demise – and before the expansion of Netted Ware to the north – , can be depicted thus as follows:

bronze_age_early_cut
Early Bronze Age Europe.

Territories in cyan must then represent, for some people who believe in an archaic Indo-Slavonic of sorts, the famous Fennoscandian Balto-Slavic to the north (before they were displaced by incoming Finno-Saamic peoples of hg N1c during the Iron Age and up to the Middle Ages); and the also famous Tundra-Forest Indo-Iranian in the Upper Volga area, a great environment for the development of the two-wheeled chariot…

But let’s leave the discussion on imaginary IE dialects for another post, and continue with the real question at hand.

A steppe funerary connection?

Back to Złota as a transitional culture, we have already seen how the corded ware vessels characteristic of the Classic CWC are related to Globular Amphora tradition, and show no break with this culture. It is usually believed that the funerary rites were adopted from steppe influence, too. That is probably right; but it does not mean that it came from Yamna or other coeval (or previous) steppe culture; at least not directly.

NOTE. A similar problem is seen when we read that Mierzanowice or Trzciniec show “Corded Ware” traits from a neighbouring CWC group, when CWC groups disappeared long before these cultures emerged. For cultural groups that are separated centuries from each other, an assertion as to their relationship needs specifics in terms of dates and material connection, or it is plainly wrong.

These are the funerary ritual features from Złota (later specialized in Corded Ware), as described by Włodarczak (2017):

  • Single burial graves; along with the habit of interring the deceased in multiple burial graves, but emphasizing their individual character by careful deposition of the body and personal nature of the grave goods.
  • Grave goods with materials and stylistiscs belonging to an older system (e.g. amber products); and others correlated to the ‘new world’ of the CWC, such as flint products made of the raw materials tipical of Lesser Poland’s CWC, copper ornaments, stone shaft-hole axes, bone and shell ornaments, and characteristic forms of vessels like beakers and amphoras.
  • Military goods, which would become prevalent in later periods, are present in a moderate number, compatible with their lesser importance.
  • There are also cases of the characteristic catacomb (“niche”) graves – with an entrance pit, a more extensive niche, and a narrow corridor leading to a vault – , as well as some individual cases of application of ochre and deformation of skulls.

It seems that the Złota funerary tradition was also “transitional”, like corded ware vessels, into the classical Corded Ware ideology. But “transitional” from what exactly? Yamna? Probably not.

The Lublin-Volhynia culture

One needs not look for a too distant culture to find similarities. Włodarczak (2017) points to CWC in south-eastern Poland and Kuyavia showing, by the time of the Yamna expansion, a funeral rite and features of the material culture without straightforward analogies in the world of north Pontic communities, and thus suggests that the “A-horizon” is a local phenomenon of central European origin.

This assertion is interesting, in so far as most Corded Ware samples investigated to date seem to come precisely from an East-Central territory near the Ukraine forest steppe, with a cluster already established by the end of the 5th millennium:

The following text is from Stanisław Wilk (2018), about the Lublin-Volhynian (and related) cemeteries at Wyciąże and Książnice:

lublin-volhynia-culture
A reach of the Wyciąże-Złotniki group and Lublin-Volhynian culture in the south-eastern Poland and western Ukraine: 1. Area of the Wyciąże-Złotniki group; 2. Area of the Lublin-Volhynian culture. A.

Wilk based on Zakościelna 2006 and Nowak 2014, on a background downloaded from https://maps-for-free.com/).

Regardless of the differences between the two necropolises (such as the number of burials, the area which has been explored, the orientation and layout of burials), it seems that they have several key elements in common:

  • concentration of graves in separate cemeteries;
  • differentiation of burials with regard to sex (the principle of the ‘left ̶ right’ side, different burial goods for males and females);
  • stratification of graves with regard to the richness of their inventories (this mainly applied to copper artefacts);
  • occurrence of indicators of the richest male burials (a copper dagger in Wyciąże, a copper battle axe, a small axe and a chisel in Książnice);
  • allocation of a separate area for elite burials (the eastern burial area in Książnice, and the southeastern and north-central part of the necropolis in Wyciąże), as well as one for egalitarian burials (the western area in Książnice, and the south-central and western part of the cemetery in Wyciąże).

Plan of the Lublin-Volhynian culture cemetery at site 2 in Książnice: 1. female graves; 2. man graves; 3. copper traces; 4. cenothap; 5. cremation grave; 6. partial grave; 7. estimated area of the L-VC cemetery; 8. estimated area of an elite and poor burial fields; 9. area of burials containing copper artefacts (drawing by S. Wilk).

The above-mentioned characteristics prove that the patterns of social and religious behaviours from areas lying beyond the Carpathian Mountains exerted a strong influence on the two societies living in Lesser Poland.

Anna Zakościelna, while describing the similarities between the burial ritual of the late Polgár groups and cultures from areas on the Tisza river and the Lublin-Volhynia culture, claimed that:

a characteristic feature of the burial ritual of both cultures was practicing various group norms, which required different treatment of the deceased depending on their sex, age and social rank. As in the Lublin-Volhynia culture, the opposition ‘male – female’ can the most clearly be observed ̶ particularly, in the consistent positioning of males on the right, and females, on the left side. And, there is much indication that this ritual norm divided the deceased from early childhood (Sofaer Derevensky 1997: 877, Tab. 1; Lichter 2001: 276- 280, 322-323) (Zakościelna 2010: 227-228).

It seems that these observations can also be extended to the Wyciąże-Złotniki group.

Another question is whether the evidence of the influences of the copper civilization observed in both cemeteries emerged as a result of the literal copying of patterns from the south, or whether the latter were only a source of inspiration for local solutions.

Looking at this problem form the perspective of the details of burial ritual, between the Carpathian Basin and Lesser Poland, we can observe clear differences, among others, in the size of cemeteries and orientation of burials. While, in the Carpathian Basin there were large necropolises, consisting of several dozen burials located in rows, with the dominant orientation along the SE-NW and E-W axis (Lichter 2001: Abb. 123, 143; Kadrow 2008: 87); in Lesser Poland there were small cemeteries of several to a dozen or so burials, mostly oriented along the S-N axis (in the Lublin-Volhynia culture; Zakościelna 2010: 66), as well as S-E and NE-SW (in the Wyciąże-Złotniki group; Kaczanowska 2009: 77). Similarly, there are differences in the details of the burial goods. North of the Carpathians, there is a much smaller frequency of copper artefacts, particularly in the group of prestigious, heavy items (battle axes, axes and daggers), as well as a complete lack of objects made of gold. Want is more, the pottery found in the graves has a distinct local character, only supplemented by imitating or imports from areas beyond the Carpathians (Zakościelna 2006: 85; Nowak 2014: 273; a different opinion Kozłowski 2006: 57). Therefore, the suggestion made by Nowak seems right ̶ namely, that these influences were not caused by migrations of groups of the population living on the Tisza river to Lesser Poland, but were rather due to processes of selective cultural transmission (Nowak 2014: 273).

Therefore, the sharing of a similar funerary rite (as happened later between Lublin-Volhynia and Złota), although it shows a strong cultural connection with autochthonous cultures, is obviously not the same as sharing ancestors; and even if it were so, they would not need to be paternal ancestors. But it shows that important Corded Ware cultural traits are local developments, and it disconnects thus still more supposed CWC ‘steppe traits’ from steppe cultures, and connects them with the first steppe-related cultural wave that reached central Europe in the 5th millennium BC.

Prehistoric Pontic—Caspian links

How would a Lublin-Volhynia culture be related to the North Pontic area ca. 4500-3000 BC? We can enjoy the map series of Baltic—Pontic migrations by Viktor Klochko (2009), and make a wild guess:

baltic-pontic-routes
Pontic—Baltic routes of migrations during the Eneolithic. Top left: Linear Pottery expansion. Top right: Funnel Beaker expansion. Bottom left: late Trypillia expansion. Bottom right: GAC expansion.

And then read the account of Sławomir Kadrow, in Exchange of People, Ideas and Things between Cucuteni-Trypillian Complex and Areas of South-Eastern Poland (2016):

In the second half of the 5th millennium BC (horizon 1), communities of the Tripolye culture, phases BI-BII, had contacts with the population of the late (IIa) phase of the Malice culture. The areas settled by both cultural complexes were located at a great distance from each other. The communities of the Tripolye culture adopted selected features of Malice ceramic production (fig 2). This seems to have resulted from marital exchange: on a moderate scale, Tripolye men sought out their wives in the area of the Malice culture and, according to patrilocal marriage customs, the women then moved to the Tripolye settlements, sporadically transferring ready-made ceramic products, so-called imports, to the Tripolye culture. Thus, the wives were responsible for the considerably more numerous imitations of the Malice ceramics and the long-lasting, though selective, traditions of Malice pottery passed down in their new environment. The patrilocal marriage customs involving the Malice women and the Tripolye men (never the other way round), and the fact that pottery was women’s domain, led to the unidirectional transfer of vessels, technology and norms of ceramic production from the Malice culture to the Tripolye culture.

The turn of the 5th and the 4th millennia and the early 4th millennium BC (horizon 2) witnessed the deepening interaction between the populations of the youngest (IIb) phase of the Malice culture and the classic (II) phase of the Lublin-Volhynia culture on the one hand and the communities of phase BII of the Tripolye culture on the other. The Danube and the Tripolye settlement complexes came into contact on the upper Dniester and between the Styr and the Horyn rivers in Volhynia. This helped to continue the previous forms of marital exchange, which resulted in further popularisation of the ceramics and the traditions of ceramic production typical of the Danube cultures, i.e. the Malice and the Lublin-Volhynia cultures, and also the Polgár culture, in the areas settled by the Tripolye cultural complex.

As the civilizational norms of the Eneolithic (Copper) Age became widespread in that period, the forms of interaction described above acquired new elements. The deepening internal diversification of the early Eneolithic communities of the Lublin-Volhynia culture led to a growing demand for prestige objects, which was met with import or imitation of copper artefacts, mainly those from the Carpathian Basin, and with flint tools produced from long blades. That type of flint production depended largely on new technologies derived from the Tripolye culture, as proven by such borrowings as troughlike retouch or the very idea and technology for the production of long flint blades in the Lublin-Volhynia culture. It seems that the influx of Tripolye settlers into flintbearing areas in Volhynia and on the upper Dniester, adjacent to the settlement centres of the late phase of the Malice culture and the Lublin-Volhynia culture, created sufficient conditions for the expanding influence of the Tripolye flint working on the communities of the Eneolithic Lublin-Volhynia culture.

In the mid-4th millennium BC (horizon 3), those forms of interaction between the Danube communities (the late phase of the Lublin-Volhynian culture) and the Tripolye communities (phase CI)were continued. Elements of the Danube pottery still grew in popularity in the Tripolye population, while selected features of the Tripolye flint working were adopted by the Lublin-Volhynia culture.

In that period, the population of the Funnel Beaker culture of the pre-classic and early classic phases (the beginnings of Gródek 1 and Bronocice III), until then absent from those areas, quite quickly drove out and replaced the Danube population in western Volhynia and the upper Dniester basin. This caused significant changes in the forms and intensity of the intercultural interaction, which became fully apparent already in the 2nd half of the 4th millennium BC.

In the following period (horizon 4), the population of the classic phase of the Funnel Beaker culture (Gródek 1, Bronocice III) settled more and more intensively the upper Dniester basin, up to the Hnyla Lypa river, and western Volhynia, up to the Styr river. East of those rivers, the Funnel Beaker settlers created considerable areas where they mixed with settlers from early phase CII of the Tripolye culture. Their coexistence, lasting there for many generations, resulted in deepening the interactions between members of both cultural complexes and in developing entirely new forms of relationships.

(…)

The intensifying interaction between the communities of the Funnel Beaker culture and the Tripolye culture, early phase CII, in the 2nd half of the 4th millennium BC (horizon 4) was an introduction to, and perhaps a condition for, even more frequent contacts in the next period, the first centuries of the 3rd millennium BC (horizon 5). In that case, the interaction was mainly triggered by multidirectional migrations of larger human groups, involving a significant part of the population of all cultures from the areas discussed here. The Tripolye communities of younger phase CII settled Volhynia, its eastern areas in particular, from the south and the south-east, while groups representing the younger phases of the Funnel Beaker culture (Gródek 2), often with Baden features (Bronocice IV and V), moved increasingly into the western part of that region. The Yamna communities expanded along the lower and central Danube to the west, whereas the populations of the late phase of the Baden culture took the opposite direction, reaching as far as Kiev in the northeast, and contributed to the cultural character of the Sofievka group.

The communities of the Globular Amphora culture migrated from the north-west, from eastern Poland, towards the Danube Delta and as far as the Dnieper in the east, while the multicultural population from the areas around the mouth of the Danube moved in the opposite direction, carrying with them cultural elements from Thrace, or even from Anatolia. Some of them returned to the starting point (to south-eastern Poland), bringing with them a new form of pottery, so-called Thuringian amphora, borrowed from the late Trypillian Usatovo group. This resulted in origins of the Złota culture, a cultural phenomenon that gave beginnings to the oldest Corded Ware culture. Inventories of both cultures contained the already mentioned Thuringian amphorae.

Here is a more recent assessment (2017) of the latest radiocarbon analyses of the available settlements of cultures in the area, published by Marek Novak (announced in a previous post), which gives the following data on Wyciąże-Złotniki, Lublin-Volhynia, and Wyciąże/Niedźwiedź:

This scheme unambiguously suggests both the overlapping and contiguous nature of cultural development in western Lesser Poland within the Middle Neolithic. The basic elements of this development are: 1) the Wyciąże-Złotniki group and the Lublin-Volhynian culture, until c. 3650–3550 cal BC; 2) the Funnel Beaker culture proper, which appeared c. 3750–3700c al BC, and existed until c. 3300–3250 cal BC, perhaps accompanied by the Wyciąże/Niedźwiedź materials from c. 3650–3550 cal BC; and 3) the Baden culture and the Funnel Beaker/Baden assemblages from 3100 and 3300–3100 cal BC, respectively, until 2850–2750 and 2850 cal BC, with – possibly – later Funnel Beaker culture and Wyciąże/ Niedźwiedź materials, existing until c. 3100 cal BC.

The final scheme shows that the Lublin-Volhynian culture could have coincided with the Wyciąże-Złotniki group. In view of the territorial relationship between them, relations from the point of view of material culture, primarily in the field of pottery, become particularly interesting. It is relatively easy to see clear similarities between these units. However, the most evident similarities apply only to some categories of ceramics, including, for example, vessels with Scheibenhenkel handles. What is more, in the period between the late 38th and early 36th centuries BC, the early Funnel Beaker and possibly early Baden influences are superimposed on this Lublin-Volhynian/Wyciąże-Złotniki ‘mix’.

[About Corded Ware: The] development of this unit in central Europe, including western Lesser Poland, [] usually point to c. 2800 cal BC (Włodarczak 2006a). (…) the calibration curve makes it possible to alternatively refer several dates earlier than c. 3100 to c. 2850–2800 cal BC.

Conclusion

There is no direct archaeological link of Lublin-Volhynia-related groups with Corded Ware, beyond the fact that they shared homeland and Central European (‘steppe-related’) traits, as found in the Złota culture. But there is no direct link of Yamna with Corded Ware, either, whether in terms of culture or population.

So, given the evident link of R1a-Z93 and steppe ancestry with the forest steppe ca. 4000 BC, the surrounding North Pontic areas in contact along the Dniester, Dnieper, Bug, and Prut are the best candidates for the appearance of R1a-Z283: steppe cultures to the south and south-west; sub-Neolithic (Comb Ware) groups to the north in the forest zone; and Eneolithic groups to the west and north-west.

Seeing how ‘ancestral components’ and PCA cluster can change within a few generations, the question of the spread of R1a-Z645 subclades is still not settled by a single sample in Alexandria. However, based on the explosive expansions we are seeing from small territories, it would not be surprising to find R1a-Z93 and R1a-Z283 side by side in the same small area within the forest steppe.

NOTE. An archaeological link may not mean anything relevant in genetics, especially – as in this case – when no clear migration event has been traced to date. We have seen exactly that with Kristiansen’s proposal of a long-term genetic admixture of Yamna with Trypillia and GAC to form Corded Ware, which didn’t happen. The cultural and ideological connection of CWC peoples with Lublin-Volhynian tradition may be similar to the already known connection with GAC, and not mean anything in genetic finds; at least in terms of Y-DNA haplogroup.

We believed in the 2000s that Corded Ware represented the expansion of Late Proto-Indo-European, because the modern map of haplogroup R1a showed a distribution similar to how we thought the European and Indo-Iranian languages could have expanded. This has been proven wrong, and that’s what ancient DNA is for; not to confirm the own ideas or models, or to support modern ideologies.

It is impossible to know if R1a-Z645 comes from the steppe, forest steppe, or forest zone, until more samples are published. I don’t think there will be any big surprise, no matter where it is eventually found. By now, adding linguistic reconstruction to archaeological traits, and to the genetic data from Yamna and Corded Ware settlers, the only clear pattern is that patrilineal clans expanded, during the Final Eneolithic / Chalcolithic:

  • Late Proto-Indo-European with Yamna and R1b-L23 subclades, given the known genomic data from Khvalynsk, Yamna, Afanasevo, Bell Beaker, Catacomb, and Poltavka—Sintashta/Potapovka.
  • Uralic with Corded Ware and R1a-Z645 subclades, given the known genomic data from Fennoscandia and the Forest Zone.

Everything else is just wishful thinking at this moment.

Mitogenomes show likely origin of elevated steppe ancestry in neighbouring Corded Ware groups

west-yamna-corded-ware

Open Access Mitochondrial genomes reveal an east to west cline of steppe ancestry in Corded Ware populations, by Juras et al., Scientific Reports (2018) 8:11603.

Interesting excerpts (emphasis mine, references have been deleted for clarity):

Ancient DNA was extracted from the Corded Ware culture individuals excavated in southeastern Poland (N = 12) and Moravia (N = 3). Late Eneolithic (N = 5) and Bronze Age human remains (N = 25) originated from western Ukraine and came from the Yampil barrow cemetery complex located in the north–western region of the Black Sea. Bronze Age individuals were associated with different archaeological cultures, including Yamnaya (N = 14), Catacomb (N = 2), Babyno (N = 4) and Noua (N = 5).

The PCA results described 50.62% of the variability and were combined with the k-means clustering (with the k value of 5 as the best representation of the data, at the average silhouette of 0.2608). Based on these results individuals associated with the western and eastern Yamnaya horizon (YAE and YAW in Fig. 2) were grouped within a cluster consisting of populations from central Eurasia and Europe (blue cluster) including people associated with eastern Corded Ware culture (CWPlM) and Baltic Corded Ware culture (CWBal). This cluster did not contain any populations linked with early Neolithic farmers (red), or hunter-gatherers (green and yellow). On the other hand, k-means clustering linked the western Corded Ware culture-associated population (CWW) with Near East and Neolithic farmer ancestry groups from western and central Europe.

Loading vectors, representing mitochondrial haplogroup contributions, are highlighted as grey arrows. Populations are grouped into four clusters according to k-means.

Pairwise mtDNA-based FST values, visualized on MDS using the raw non-linearized FST (stress value = 0.099) (Fig. 4), also supported the PCA results and indicated that western and eastern Yamnaya horizon groups (YAW and YAE) were closer to people associated with the eastern Corded Ware culture (CWPlM) (FST = 0.00; FST = 0.01, respectively; both p > 0.05) and Baltic Corded Ware culture (CWBal) (FST = 0.00; FST = 0.00, respectively; both p > 0.05), than to populations associated with the western Corded Ware culture (CWW) (FST = 0.047 and FST = 0.059, respectively; both statistically significant p < 0.05). Western and eastern Yamnaya horizon groups also showed close genetic affinity to the Iron Age western Scythians (SCU) (FST = 0.0022 and FST = 0.006, respectively, both p > 0.05). The most distant populations to the Yamnaya horizon groups were western hunter-gatherers (HGW) (FST = 0.23 and FST = 0.15, p < 0.001). The FST-based MDS reflected the general European population history in the post-LGM period as the three highest FST scores were detected between western hunter-gatherers (HGW) and people associated with Linear Pottery culture (LBK) (FST = 0.33, p < 0.001), between eastern hunter-gatherers (HGE) and Baltic hunter-gatherers (HGBal) (FST = 0.35, p < 0.05), and between western (HGW) and eastern hunter-gatherers (HGE) (FST = 0.36, p < 0.05). The Yamnaya horizon groups (YAE and YAW) were placed centrally between northern hunter-gatherers (HGN) and Neolithic farmers (LDN), in direct proximity to the Bronze and Iron Age populations from Eastern Europe (SCU, BARu, SRU) and close to individuals associated with eastern and Baltic Corded Ware culture.

Among the analyzed samples, we identified two Catacomb culture-associated individuals (poz220 and poz221) belonging to hg X4. They are the first ancient individuals assigned to this particular lineage. Haplogroup X4 is rare among present day populations and has been found only in one individual each from Central Europe, Balkans, Anatolia and Armenia.

Moreover, we have reported mtDNA haplotypes that might be associated with the migration from the steppe and point to genetic continuity in the north Pontic region from Bronze Age until the Iron Age. These haplotypes were assigned to hgs U5, U4, U2 and W3. MtDNA hgs U5a and U4, identified in this study among Yamnaya, Late Eneolithic and Corded Ware culture-associated individuals, have previously been found in high frequencies among northern and eastern hunter-gatherers. Moreover, they appeared in the north Pontic region in populations associated with Mesolithic (hg U5a), Eneolithic (Post-Stog) (hg U4), Yamnaya (hgs U5, U5a), Catacomb (hgs U5 and U5a) and Iron Age Scythians (hg U5a), suggesting genetic continuity of these particular mtDNA lineages in the Pontic region from, at least, the Bronze Age. Hgs U5a and U4-carrying populations were also present in the eastern steppe, along with individuals from the Yamnaya culture from Samara region, the Srubnaya and the Andronovo from Russia. Interestingly, hg U4c1 found in the Yamnaya individual (poz224) has so-far been found only in two Bell Beaker- associated individuals and one Late Bronze Age individual from Armenia, which might suggest a steppe origin for hg U4c1. A steppe origin can possibly also be assigned to hg U4a2f, found in one individual (poz282) but not reported in any other ancient populations to date, and to U5a1- the ancestral lineage of U5a1b, reported for individual poz232, which was identified not only in Corded Ware culture-associated population from central and eastern Europe, but also in representatives of Catacomb culture from the north Pontic region, Yamnaya from Bulgaria and Russia, Srubnaya and Andronovo-associated groups. Hg U2e, reported for Late Eneolithic individual (poz090), was also identified in western Corded Ware culture-associated individual and in succeeding Sintashta, Potapovka and Andronovo groups, suggesting possible genetic continuity of U2e1 in the western part of the north Pontic region.

Hgs W3a1 and W3a1a, found in two Yamnaya individuals from this study (poz208 and poz222), were also identified in Yamnaya-associated individuals from the Russia Samara region and later in Únětice and Bell Beaker groups from Germany, supporting the idea of an eastern European steppe origin of these haplotypes and their contribution to the Yamnaya migration toward the central Europe. The W3a1 lineage was not identified in Neolithic times and, thus, we assume that it appeared in the steppe region for the first time during the Bronze Age. Notably, hgs W1 and W5, which predate the Bronze Age in Europe, were found only in individuals associated with the early Neolithic farmers from Starčevo in Hungary (hg W5), early Neolithic farmers from Anatolia (hg W1-T119C), and from the Schöningen group (hg W1c) and Globular Amphora culture from Poland (hg W5).

Some comments

The most recent radiocarbon dates show that Early Yamna expanded to the west with Repin settlers of the Lower Don ca. 3350/3300 BC. At the end of the 4th millennium, then, these settlers dominated over groups whose population had in turn also elevated ‘steppe ancestry’ (at least from ca. 4000 BC, as shown by Ukraine Eneolithic samples from the forest-zone), and probably replaced the male population completely, as evidenced by other Yamna and Poltavka, and later Bell Beaker, Catacomb, and Sintashta samples.

The ‘second wave’ of expansion of Yamna settlers to the west, into east-central European steppes, began probably ca. 3100/3000 BC, and – based on material culture – stemmed mainly from the North Pontic area. The Yampil Barrow Complex on the Dnieper (which I recently wrote about) seems to be part of one of the groups of western Yamna migrants: those who migrated westward from the left bank of the Dniester to the west into the Prut-Siret region, and north along the Prut.

This region is the key for population movements that gave rise to the Corded Ware culture (see another recent post on Corded Ware origins). It is quite likely that we will see a dance of late Trypillia / Usatovo, GAC, (Proto-)Corded Ware, and Yamna samples in this area. Judging by the clear-cut Y-DNA bottlenecks we are seeing in Neolithic populations, especially among steppe pastoralists, the difference between groups in recovered ancient samples will not only be clear from their culture, but also from their male lineages.

Based on the number of burials studied from the different settlement regions for West Yamna migrants, the Prut-Siret group was one of the smallest new Yamna ‘provinces’ in south-eastern Europe, and was probably overrun early, although – since kurgan findings continued into the Catacomb culture in the Yampil complex – the Dnieper region was well-enough connected to the core North Pontic area to be kept into its retreating territory by 2500 BC, as was the Danube delta, in contrast with other east-central European areas.

steppe-chalcolithic-migrations
Steppe-related migrations ca. 3100-2600 BC with tentative linguistic identification.

Taking into account that the earliest Corded Ware burials are from ca. 2900 BC (in the Single Grave culture), and that the earliest A-horizon pottery expanded from Lesser Poland (a syncretic pottery based on the previous GAC-type) a century later, it is likely that what this paper shows for Corded Ware in eastern Europe and the Baltic is what I have suggested many times (see here, or here) as the most likely reason for elevated steppe ancestry (and close PCA cluster) of the Baltic LN ‘outliers’: the exogamy of Corded Ware groups with females from Yamna or a North Pontic steppe culture with similar ancestry.

If Proto-Corded Ware populations of the North Pontic region did not have an identical “steppe ancestry” to these eastern CW groups already during the Eneolithic (which is the other possibility), I might be right in their more recent exogamy, and this could be seen in this study by the close cluster of east Corded Ware (especially Baltic) mtDNA to GAC and Yamna West groups, and distant from previous hunter-gatherer populations of the area, which suggests that expanding males from the Volhynia/Podolia region practiced exogamy mainly with southern groups.

I think this is probably related to demographic pressure imposed on other populations by the explosive expansion of pastoralists with their new subsistence economy (part of the “Secondary Products Revolution”), which the hunter-gatherer and farmer population of Europe could not keep up with (as seen later in the admixture of expanding East Bell Beakers), although studies on European prehistoric demography are scarce and too general to tell us anything relevant for this precise period and region.

Corded Ware culture origins: The Final Frontier

corded-ware-yamna-bell-beaker

As you can imagine from my latest posts (on kurgan origins and on Sredni Stog), I am right now in the middle of a revision of the Corded Ware culture for my Indo-European demic diffusion model, to see if I can add something new to the draft. And, as you can see, even with ancient DNA on the table, the precise origin of the Corded Ware migrants – in spite of the imaginative efforts of the Copenhagen group to control the narrative – are still unknown.

Corded Ware origins

The main objects of study in Corded Ware origins are necessarily the region where the oldest Corded Ware vessels appeared, Lesser Poland, as well as the adjacent (traditionally considered Proto-Corded Ware regions) Volhynia, Podolia, and upper Dniester river basin. These are some relevant points, continuing where I left the Eneolithic steppe developments (following Szmyt 1999, Rassamakin 1999, Kadrow 2008, Furholt 2014):

gac-trypillia-yamna-usatovo
Kadrow (2008). Cultural interactions around Carpathians at the beginnings of the 3rd millennium BC: 1 – Globular Amphora culture; 2 – Sofievka group of Trypillia culture; 3 – Funnel Beaker culture; 4 – Baden culture; 5 – Kostolac culture; 6 – Coţofeni culture; 7 – Cernavoda II culture; 8 – Yamnaya culture and Usatovo group of Trypillia culture (apud Kadrow, 2001).
  • More frequent contacts were seen ca. 3500-3000 BC, with an interaction showing multidirectional migrations of larger human groups in the centuries around 3000 BC, involving a significant part of the population of central-east Europe.
  • The easternmost area of the Funnel Beaker culture had become more Baden-like with the expansion of the Baden culture in its western area ca. 3300-2900 BC (with findings up to 2600 BC), and these younger groups with Baden features moved increasingly into the western part of Volhynia.
  • The influence of the neighbouring Trypillian culture is seen in the eastern parts of Volhynia, from ca. 3000 BC, either from a younger phase CII (cf. Troyaniv, Koshilivtsy, Brînzeni, Zhvaniets, or Vychvatintsy) or later groups (cf. Gorodsk, Kasperivtsy, Sofievka, Horodiştea-Folteşti, Usatovo).
  • In the forest-steppe zone, herding and hunting activities intensified, while agricultural traditions were preserved, as shown by the Sofievka, Kasperivtsy, and Gorodsk groups. From the end of the 4th millennium BC mobile parts of the late Trypillian populations moved to the steppe zone, absorbing more and more steppe elements; among others, cord ornamentation (in Vykhvatintsy, Troyaniv, and Gorodsk groups), pottery forms (Vykhvatintsy, which served as prototype for the Thuringian Apmphorae, dispersed along the Dniester river, too), flat burials with bodies in contracted position on the left or right side (Vykhvatintsy, reminding of Polgár culture different male-female position, and later Corded Ware burials, and also Lower Mikhailovka, under a mound without stone constructions). At the end of the Trypillia culture, its agricultural system collapsed completely.
gac-trypillia-usatovo-corded-ware
Globular Amphorae culture „exodus” to the Danube Delta: a – Globular Amphorae culture; b – GAC (1), Gorodsk (2), Vykhvatintsy (3) and Usatovo (4) groups of Trypillia culture; c – Coţofeni culture; d – northern border of the late phase of Baden culture;red arrows – direction of Globular Amphora culture expansion; blue arrow – direction of „reflux” of Globular Amphora culture (apud Włodarczak, 2008, with changes).
  • Slash and burn techniques of agriculture – especially those practiced by Trypillian and Funnel Beaker populations – must have intensified effects of natural growth of humidity (ca. 3400-2400), increasing fluvial activities in west Ukrainian river valleys, and increasing deforestation processes, which favoured pastoralism and nomadisation of the settlement system, and a consequent change of the social structure
  • At the same time, Yamna communities expanded along the lower and central Danube to the west, while the populations of the late phase of the Baden culture took the opposite direction and reached as far as Kiev in the north-east, contributing to the culture of the Sofievka group.
  • Globular Amphora communities migrated from the north-west, from eastern Poland, towards the Danube Delta and as far as the Dnieper in the east, destroying the primary structures of the communities in the supposed cradle territories of the Corded Ware culture. These communities found refuge and conditions for further development in south-eastern margin zone of the Funnel Beaker culture territories, penetrating at first the upper parts of the loess uplands like typical Funnel Beaker sites, but on the margins of their range, and also on areas avoided by Funnel Beaker settlement agglomerations. They brought with them the so-called Thuringian amphora up to Lesser Poland, borrowed from the late Trypillian Usatovo group. This resulted in the Złota culture, which eventually gave rise to the A-Amphorae.

In the end, we are left with this information about the oldest CWC (Furholt 2014):

  • The earliest radiocarbon-dated groups associated with the Corded Ware culture come from new single graves from Jutland in Denmark and Northern Germany, ca. 2900 BC. This Early Single Grave culture is associated with the appearance of individual graves (some time after the decline of the megalithic constructions), composed of a small round barrow and a new gender-differentiated burial practice emphasising male individuals orientated west-east (with regional exceptions), combined with the internment with new local battle-axe types (A-Axe). However, there is no single type of burial or burial custom in Corded Ware:
    • In southern Sweden the prevailing orientation is north-east – south-west, and south-north, contrary to the supposed rule male individuals are regularly deposited on their left and females on their right side.
    • In the Danish Isles and north-eastern Germany, the Final Neolithic / Single Grave Period is characterized by a majority of megalithic graves, with only some single graves from typical barrows. In south Germany, west-east and collective burials prevail, while in Switzerland no graves are found.
    • In Kujawia (south-eastern Poland), Hesse (Germany), or the Baltic, west-east orientation and gender differentiation cannot be proven statistically.
corded-ware-regions-main
Furholt (2014). Map of the Corded Ware regions of central Europe. The dark shading indicates those regions where Corded Ware burial rituals are present regularly
  • The oldest Corded Ware vessels (the A-Amphorae, which define the A-Horizon of the CWC) come probably from the Złota (or a related) group in Lesser Poland, where a mixed archaeological culture connecting Funnel Beaker, Baden, Globular Amphorae and Corded Ware appears ca. 2900-2600 BC. No cultural (typological) break is seen between earlier Globular Amphorae and the first Corded Ware Amphorae, but rather a continuum of traits and characteristics among the recovered vessels. This strengthens the connection of Corded Ware with Globular Amphorae peoples. The A-horizon expanded thus probably from Lesser Poland ca. 2800-2600, as seen in local contexts.
  • And of course we have a third way of defining Corded Ware individuals, which is the presence of herding, and thus a transition from hunter-gatherers to agropastoralists. This is how some Baltic Late Neolithic individuals with no archaeological data have been classified as members of the Corded Ware culture: Even though no cultural remains were extracted with the two ‘outlier’ individuals, their haplogroup and ancestry point to a direct origin in or around the steppe and forest-steppe region (yes, that risks circular reasoning).
globular-amphorae-corded-ware-zlota-amphorae
Correspondence analysis of amphorae from the Złota-graveyards reveals that there is no typological break between Globular Amphorae and Corded Ware Amphorae, including ‘Strichbündelamphorae’ (after Furholt 2008)

Corded Ware peoples in genetics

So, no clear origin of Corded Ware migrants, a lot of data pointing to intense migrations and interaction among GAC, Trypillia and the western steppe population (remember Kristiansen’s ‘long-lasting GAC-CWC connection’, now ignored to favour their Yamnaya admixture™ concept), and also three ways of defining Corded Ware culture…

Maybe genetics can help:

Ukraine Neolithic cultures – mainly from Dereivka – show haplogroups R1b-V88, R1a1, and R1b-L754 (xP297, xM269), which is similar to the haplogroup distribution found in Ukraine Mesolithic, but apparently with an expanding group marked by haplogroup I2a2a1b1 (possibly I2a2a1b1b).

The first thing that stands out about Ukraine Eneolithic samples is that only two of them can be said to be really Ukraine Eneolithic (i.e. from “Sredni Stog”-related groups):

  • I5876 (Y-DNA R1a-Z93(Y3+), mtDNA U5a2a), from Alexandria, 4045-3974 calBCE (5215±20BP, PSUAMS-2832)
  • I4110 (mtDN AJ2b1), from Dereivka, 3634-3377 calBCE (4725±25 BP, UCIAMS-186349), J2b1

The other two samples are quite late, and in fact one of them is clearly too late (maybe from the Catacomb culture):

  • I5882 (mtDNA U5a2a), from Dereivka, 3264-2929 calBCE (4420±20BP, PSUAMS-2826)
  • I3499 (Y-DNA R1b-Z2103, mtDNA T2e), from Dereivka, 2890-2696 calBCE (4195±20BP, PSUAMS-2828)

Corded Ware samples from Mittnik et al. (2018) offer very wide radiocarbon dates, so it is unclear which of them may be the oldest one. Most of them cluster closely to the older Ukraine Eneolithic sample I5876, but also to later steppe_MLBA samples i.e. Sintashta, Potapovka, and especially Srubna and Andronovo). This points to a genetic continuity from Pre-Corded Ware to Classic and late Corded Ware peoples. Therefore, much like Khvalynsk-Yamna and apparently many other Neolithic cultures, these peoples did not really admix; at least not with the male population.

pca-mittnik-late-neolithic
File modified by me from Mittnik et al. (2018) to include the approximate position of the most common ancestral components, and an identification of potential outliers. Zoomed-in version of the European Late Neolithic and Bronze Age samples. “Principal components analysis of 1012 present-day West Eurasians (grey points, modern Baltic populations in dark grey) with 294 projected published ancient and 38 ancient North European samples introduced in this study (marked with a red outline).

Lucky for us, even though the culture remains undefined, haplogroup R1a-Z645 seems like a unifying trait, as I said long ago, so we only have to wait for more samples to trace their origin. Nevertheless, it is clear that Corded Ware may not have been as genetically homogeneous as Khvalynsk, Yamna and Yamna-related cultures, further supporting its archaeological complexity:

  • Jagodno1 and Jagodno2 (Silesia), dated ca. 2800 BC, show haplogroup G? and I/J? – compatible with an origin of CWC in common with Trypillia (which shows 3 samples of haplogroup G2a2b2a, and one E) and Ukraine Neolithic (showing the expansion of I2a2a1b1 subclades).
  • I7272, from Brandýsek (Czech Republic), dated ca. 2900-2200 BC shows haplogroup I2a2a2 (compatible with an origin in Ukraine Neolithic peoples – this haplogroup is also found in Yamna Kalmykia and in the Yamna Bulgaria outlier, i.e. late western samples from the Early Yamna culture).

NOTE. This precise subclade is only present to date in Chalcolithic samples from Iberia, which points (possibly like the Esperstedt family) to local Central European haplogroups integrated in a mixed Proto-Corded Ware population. The upper subclade I2a2a is found in Neolithic samples from Iberia, the British Isles, Hungary (Koros EN, ALPc), and also south-east European Mesolithic and Neolithic samples.

  • RISE1, from Oblaczkowo (Greater Poland), ca. 2865-2578 BC, shows haplogroup R1b1.
  • The Esperstedt family samples have been analysed as R1a-M417 (xZ645), although the supposed ‘xZ645’ has not been confirmed – not even in the risky new Y-calls from Wang et al. (2018) supplementary materials.

Network analysis based on the quantitative occurrence of Corded Ware pottery forms, pottery ornamentation styles, tools,

Maybe this heterogeneity is a problem of better defining the culture, but from what we can see the oldest CWC regions and the unifying ‘Corded Ware province’ – formed after ca. 2700 BC by Jutland and Northern Germany, the Netherlands, Saale, Bohemia, Austria and the Upper Danube regions – are for the moment not the most genetically homogeneous groups.

Homogeneity comes later – which we may tentatively identify with the expansion of the A-horizon from the northern Dnieper-Dniester and Lesser Poland area – , as seen around the Baltic (like the Battle Axe culture) with R1a-Z283 subclades, and around Sintashta (i.e. probably Abashevo – Balanovo) with R1a-Z93 subclades, which is compatible with the late spread of different Z645 groups (and potentially a unifying language) .

The time and place of European admixture in Ashkenazi Jewish history

Open access The time and place of European admixture in Ashkenazi Jewish history, by Xue, Lencz, Darvasi, Pe’er, & Carmi, PLOS Genetics (2018).

Abstract (emphasis mine):

The Ashkenazi Jewish (AJ) population is important in genetics due to its high rate of Mendelian disorders. AJ appeared in Europe in the 10th century, and their ancestry is thought to comprise European (EU) and Middle-Eastern (ME) components. However, both the time and place of admixture are subject to debate. Here, we attempt to characterize the AJ admixture history using a careful application of new and existing methods on a large AJ sample. Our main approach was based on local ancestry inference, in which we first classified each AJ genomic segment as EU or ME, and then compared allele frequencies along the EU segments to those of different EU populations. The contribution of each EU source was also estimated using GLOBETROTTER and haplotype sharing. The time of admixture was inferred based on multiple statistics, including ME segment lengths, the total EU ancestry per chromosome, and the correlation of ancestries along the chromosome. The major source of EU ancestry in AJ was found to be Southern Europe (≈60–80% of EU ancestry), with the rest being likely Eastern European. The inferred admixture time was ≈30 generations ago, but multiple lines of evidence suggest that it represents an average over two or more events, pre- and post-dating the founder event experienced by AJ in late medieval times. The time of the pre-bottleneck admixture event, which was likely Southern European, was estimated to ≈25–50 generations ago.

The analysis was performed using SmartPCA [25] with default parameters (except no outlier removal). The populations included within each region are listed in Table 1 of the main text. The PCA plot supports the partitioning of the European and Middle-Eastern populations into the broad regional groups used in the analysis. https://doi.org/10.1371/journal.pgen.1006644.s001

Interesting excerpts:

(…) AJ genetics defies simple demographic theories. Hypotheses such as a wholly Khazar, Turkish, or Middle-Eastern origin have been disqualified [4–7, 17, 55], but even a model of a single Middle-Eastern and European admixture event cannot account for all of our observations. The actual admixture history might have been highly complex, including multiple geographic sources and admixture events. Moreover, due to the genetic similarity and complex history of the European populations involved (particularly in Southern Europe [51]), the multiple paths of AJ migration across Europe [10], and the strong genetic drift experienced by AJ in the late Middle Ages [9, 16], there seems to be a limit on the resolution to which the AJ admixture history can be reconstructed.

Historical model and interpretation

Under our model, admixture in Europe first happened in Southern Europe, and was followed by a founder event and a minor admixture event (likely) in Eastern Europe. Admixture in Southern Europe possibly occurred in Italy, given the continued presence of Jews there and the proposed Italian source of the early Rhineland Ashkenazi communities [3]. What is perhaps surprising is the timing of the Southern European admixture to ≈24–49 generations ago, since Jews are known to have resided in Italy already since antiquity. This result would imply no gene flow between Jews and local Italian populations almost until the turn of the millennium, either due to endogamy, or because the group that eventually gave rise to contemporary Ashkenazi Jews did not reside in Southern Europe until that time. More detailed and/or alternative interpretations are left for future studies.

Recent admixture in Northern Europe (Western or Eastern) is consistent with the presence of Ashkenazi Jews in the Rhineland since the 10th century and in Poland since the 13th century. Evidence from the IBD analysis suggests that Eastern European admixture is more likely; however, the results are not decisive. An open question in AJ history is the source of migration to Poland in late Medieval times; various speculations have been proposed, including Western and Central Europe [2, 10]. The uncertainty on whether gene flow from Western Europeans did or did not occur leaves this question open.

Paths from the Middle-East into AJ are indicated with red arrows; paths from YRI to Western or Southern Europe with green arrows. The f4 statistic is proportional to the total overlap between these paths (black bars). Whereas panel (B) (f4(South-EU,YRI;AJ,ME)) has more overlapping branches than in (A), migration from the Middle-East into Southern EU introduces a branch where the arrows run in opposite directions (patterned bar). Hence, the observed f4 statistic in (B) may be lower (depending on branch lengths) than in (A), even if Southern EU is the true source of gene flow into AJ. https://doi.org/10.1371/journal.pgen.1006644.s005

The concept of “Outlier” in Human Ancestry (III): Late Neolithic samples from the Baltic region and origins of the Corded Ware culture

corded-ware-regions-main

I have written before about how the Late Neolithic sample from Zvejnieki seemed to be an outlier among Corded Ware samples (read also the Admixture analysis section on the IEDDM), due to its position in PCA, even more than its admixture components or statistical comparison might show.

In the recent update to Northern European samples in Mittnik et al. (2018), an evaluation of events similar to the previous preprint (2017) is given:

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.

NOTE: Information on the Late Neolithic burial of Zvejnieki is scarce, since it is an isolated find in radiocarbon analysis, among Mesolithic burials. You can read more about it from Ilga Zagorska’s studies, such as The use of ochre in Stone Age burials of the East Baltic (2008), The persistent presence of the dead: recent excavations at the hunter-gatherer cemetery at Zvejnieki (Latvia) (Antiquity 2013), or Dietary freshwater reservoir effects and the radiocarbon ages of prehistoric human bones from Zvejnieki, Latvia (J. Archaeol. Sci. 2016).

Samples of Baltic “Late Neolithic / Corded Ware culture”

The only two samples clustering more closely to Yamna cluster also closely to the three previous samples from Khvalynsk in Samara (labelled ‘Steppe Eneolithic’ in the paper), which makes one wonder how strongly connected were cultures from the forest and forest-steppe zones before the expansion of Corded Ware and Yamna settlers.

NOTE: Apart from the scarcity of samples available, which is common in genetic studies, the description of both additional ‘outlier’ samples of the Baltic Late Neolithic – isolated finds based mainly on radiocarbon analysis – leaves a lot to the imagination, because of the lack of cultural context and potential problems with dating methods:

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.

We can see from the additional samples in Mittnik et al. (2018) that the common cluster formed by most Baltic LN samples in PCA (most of them with clear cultural context among Late Neolithic or Corded Ware material, unlike the two ‘outliers’ and Gyvakarai1) is among Ukraine Eneolithic samples, European Corded Ware samples, and also Mesolithic-Neolithic samples from the Baltic. This is a logical find in light of the mainstream opinion that the expansion of the third horizon of the Corded Ware culture seems to have begun in the Dnieper-Dniester region (a corridor of steppe, steppe-forest, and forest zones) ca. 3300 BC.

Corded Ware culture origins

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.

Their situation in PCA among Khvalynsk (Samara), Baltic Mesolithic, East Hunger-Gatherer samples, Yamna and Eneolithic Ukraine leaves us without enough information to understand their actual origin.

EDIT (3 FEB 2018): In the first edition of my IEDDM paper I based the potential expansion of the Corded Ware culture mainly on Piezonka’s detailed analyses of the evolution of Mesolithic and Neolithic cultures in the forest-steppe and Forest Zone, and on later phylogeographic finds, since there were no samples from these regions in this interesting period. I revised it in the second edition to accomodate the model to the Indo-Uralic proto-language supported by the Leiden school, and identified it with a a close Neolithic-Chalcolithic steppe community based on common language guesstimates and – after the latest revision of Mathieson et al. (2017) – on the appearance of steppe admixture in the steppe.

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.

Martin Furholt‘s assessment of the origin of the A-horizon of the Corded Ware culture would put the early dates of Late Neolithic in the Baltic coinciding with or just before the initial expansion of Corded Ware migrants. For example, here are some excerpts (emphasis mine) from Re-evaluating Corded Ware Variability in Late Neolithic Europe (2014), in Proceedings of the Prehistoric Society (you can read it free at Academia.edu):

Radiocarbon analysis

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.

Note that the definitions of those units are far from consistent or comparable, because they derive from different national and regional research traditions. Bold letters indicate a unit connected to the Corded Ware phenonomenon

Conclusion

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.

As a summary, we can say that there is still much work to be done on the origins and expansion of the Corded Ware culture, and that speculative interpretations of recent genetic papers (especially since 2015), based solely on scarce genetic finds, are not doing much in favour of sound anthropological models by connecting directly Yamna to Corded Ware (and the latter to Bell Beaker), as the multiple new anthropological ‘steppe’ models (and their unending revisions due to the gradual corrections from ‘Yamnaya’ to ‘steppe’ admixture in genetic papers) are showing.

Recent archaeological finds near Indo-European and Uralic homelands

eneolithic-forest-zone

The latest publication of Documenta Praehistorica, vol. 44 (2017) is a delight for anyone interested in Indo-European and Uralic studies, whether from a linguistic, archaeological, anthropological, or genetic point of view. Articles are freely downloadable from the website.

The following is a selection of articles I deem more interesting, but almost all are.

On the Corded Ware culture

Do 14C dates always turn into an absolute chronology? The case of the Middle Neolithic in western Lesser Poland, by Marek Novak:

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.

baden-corded-ware-culture
Territory of western Lesser Poland and the main archaeological units in the late 5th, 4th and early 3rd millennia BC: 1 borders of the area discussed in the paper; 2 sites of the Lublin-Volhynian culture; 3 the Wyciąże-Złotniki group; 4 the Funnel Beaker culture (a dense settlement typical of ‘loess’ upland; b more dispersed settlement typical of foothills, alluvial plains/basins and ‘jurassic zones; c highly dispersed settlement typical mainly of mountainous zone); 5 sites with the Wyciąże/Niedźwiedź materials; 6 the Baden culture, 7 the Beaker/Baden assemblages; 8 Corded Ware culture (a relatively dense settlement typical mainly of ‘loess’ upland; b highly dispersed settlement typical of other ecological zones).

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.

On the Pontic-Caspian steppe and forest-steppe

First isotope analysis and new radiocarbon dating of Trypillia (Tripolye) farmers from Verteba Cave, Bilche Zolote, Ukraine, by Lillie et al.:

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.

Chronology of Neolithic sites in the forest-steppe area of the Don River, by Smolyaninov, Skorobogatov, and Surkov:

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).

Radiocarbon chronology of Neolithic in the Lower Don and North-eastern Azov Sea, by Tsybryi et al.:

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.

On the Forest Zone

The past in the past in the mortuary practice of hunter-gatherers: an example from a settlement and cemetery site in northern Latvia, by Lars Olof Georg Larsson:

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.
