The latest papers from Ning et al. Cell (2019) and Anthony JIES (2019) have offered some interesting new data, supporting once more what could be inferred since 2015, and what was evident in population genomics since 2017: that Proto-Indo-Europeans expanded under R1b bottlenecks, and that the so-called “Steppe ancestry” referred to two different components, one – Yamnaya or Steppe_EMBA ancestry – expanding with Pro-Indo-Europeans, and the other one – Corded Ware or Steppe_MLBA ancestry – expanding with Uralic speakers.
NOTE. As in the Corded Ware ancestry maps, the selected reports in this case are centered on the prototypical Yamnaya ancestry vs. other simplified components, so everything else refers to simplistic ancestral components widespread across populations that do not necessarily share any recent connection, much less a language. In fact, most of the time they clearly didn’t. They can be interpreted as “EHG that is not part of the Yamnaya component”, or “CHG that is not part of the Yamnaya component”. They can’t be read as “expanding EHG people/language” or “expanding CHG people/language”, at least no more than maps of “Steppe ancestry” can be read as “expanding Steppe people/language”. Also, remember that I have left the default behaviour for color classification, so that the highest value (i.e. 1, or white colour) could mean anything from 10% to 100% depending on the specific ancestry and period; that’s what the legend is for… But, fere libenter homines id quod volunt credunt.
Anthony (2019) agrees with the most likely explanation of the CHG component found in Yamnaya, as derived from steppe hunter-fishers close to the lower Volga basin. The ultimate origin of this specific CHG-like component that eventually formed part of the Pre-Yamnaya ancestry is not clear, though:
The hunter-fisher camps that first appeared on the lower Volga around 6200 BC could represent the migration northward of un-admixed CHG hunter-fishers from the steppe parts of the southeastern Caucasus, a speculation that awaits confirmation from aDNA.
The typical EHG component that formed part eventually of Pre-Yamnaya ancestry came from the Middle Volga Basin, most likely close to the Samara region, as shown by the sampled Samara hunter-gatherer (ca. 5600-5500 BC):
After 5000 BC domesticated animals appeared in these same sites in the lower Volga, and in new ones, and in grave sacrifices at Khvalynsk and Ekaterinovka. CHG genes and domesticated animals flowed north up the Volga, and EHG genes flowed south into the North Caucasus steppes, and the two components became admixed.
To the west, in the Dnieper-Dniester area, WHG became the dominant ancestry after the Mesolithic, at the expense of EHG, revealing a likely mating network reaching to the north into the Baltic:
Like the Mesolithic and Neolithic populations here, the Eneolithic populations of Dnieper-Donets II type seem to have limited their mating network to the rich, strategic region they occupied, centered on the Rapids. The absence of CHG shows that they did not mate frequently if at all with the people of the Volga steppes (…)
After approximately 4500 BC the Khvalynsk archaeological culture united the lower and middle Volga archaeological sites into one variable archaeological culture that kept domesticated sheep, goats, and cattle (and possibly horses). In my estimation, Khvalynsk might represent the oldest phase of PIE.
(…) this middle Volga mating network extended down to the North Caucasian steppes, where at cemeteries such as Progress-2 and Vonyuchka, dated 4300 BC, the same Khvalynsk-type ancestry appeared, an admixture of CHG and EHG with no Anatolian Farmer ancestry, with steppe-derived Y-chromosome haplogroup R1b. These three individuals in the North Caucasus steppes had higher proportions of CHG, overlapping Yamnaya. Without any doubt, a CHG population that was not admixed with Anatolian Farmers mated with EHG populations in the Volga steppes and in the North Caucasus steppes before 4500 BC. We can refer to this admixture as pre-Yamnaya, because it makes the best currently known genetic ancestor for EHG/CHG R1b Yamnaya genomes.
Three individuals from the sites of Progress 2 and Vonyuchka 1 in the North Caucasus piedmont steppe (‘Eneolithic steppe’), which harbour EHG and CHG related ancestry, are genetically very similar to Eneolithic individuals from Khvalynsk II and the Samara region. This extends the cline of dilution of EHG ancestry via CHG-related ancestry to sites immediately north of the Caucasus foothills
NOTE. Unpublished samples from Ekaterinovka have been previously reported as within the R1b-L23 tree. Interestingly, although the Varna outlier is a female, the Balkan outlier from Smyadovo shows two positive SNP calls for hg. R1b-M269. However, its poor coverage makes its most conservative haplogroup prediction R-M343.
The formation of this Pre-Yamnaya ancestry sets this Volga-Caucasus Khvalynsk community apart from the rest of the EHG-like population of eastern Europe.
Anthony (2019) seems to rely on ADMIXTURE graphics when he writes that the late Sredni Stog sample from Alexandria shows “80% Khvalynsk-type steppe ancestry (CHG&EHG)”. While this seems the most logical conclusion of what might have happened after the Suvorovo-Novodanilovka expansion through the North Pontic steppes (see my post on “Steppe ancestry” step by step), formal stats have not confirmed that.
In fact, analyses published in Wang et al. (2019) rejected that Corded Ware groups are derived from this Pre-Yamnaya ancestry, a reality that had been already hinted in Narasimhan et al. (2018), when Steppe_EMBA showed a poor fit for expanding Srubna-Andronovo populations. Hence the need to consider the whole CHG component of the North Pontic area separately:
NOTE. Fits for WHG + CHG + EHG in Neolithic and Eneolithic populations are taken in part from Mathieson et al. (2019) supplementary materials (download Excel here). Unfortunately, while data on the Ukraine_Eneolithic outlier from Alexandria abounds, I don’t have specific data on the so-called ‘outlier’ from Dereivka compared to the other two analyzed together, so these maps of CHG and EHG expansion are possibly showing a lesser distribution to the west than the real one ca. 4000-3500 BC.
Anatolia Neolithic ancestry clearly spread to the east into the north Pontic area through a Middle Eneolithic mating network, most likely opened after the Khvalynsk expansion:
Regarding Y-chromosome haplogroups, Anthony (2019) insists on the evident association of Khvalynsk, Yamnaya, and the spread of Pre-Yamnaya and Yamnaya ancestry with the expansion of elite R1b-L754 (and some I2a2) individuals:
3. Early Bronze Age
Data from Wang et al. (2019) show that Corded Ware-derived populations do not have good fits for Eneolithic_Steppe-like ancestry, no matter the model. In other words: Corded Ware populations show not only a higher contribution of Anatolia Neolithic ancestry (ca. 20-30% compared to the ca. 2-10% of Yamnaya); they show a different EHG + CHG combination compared to the Pre-Yamnaya one.
Yamnaya Kalmykia and Afanasievo show the closest fits to the Eneolithic population of the North Caucasian steppes, rejecting thus sizeable contributions from Anatolia Neolithic and/or WHG, as shown by the SD values. Both probably show then a Pre-Yamnaya ancestry closest to the late Repin population.
EBA maps include data from Wang et al. (2018) supplementary materials, specifically unpublished Yamnaya samples from Hungary that appeared in analysis of the preprint, but which were taken out of the definitive paper. Their location among Yamnaya settlers from Hungary is speculative, although most uncovered kurgans in Hungary are concentrated in the Tisza-Danube interfluve.
The Y-chromosome bottleneck of elite males from Proto-Indo-European clans under R1b-L754 and some I2a2 subclades, already visible in the Khvalynsk sampling, became even more noticeable in the subsequent expansion of late Repin/early Yamnaya elites under R1b-L23 and I2a-L699:
Maps of CHG, EHG, Anatolia Neolithic, and probably WHG show the expansion of these components among Corded Ware-related groups in North Eurasia, apart from other cultures close to the Caucasus:
The following maps show the most likely distribution of Yamnaya ancestry during the Bell Beaker-, Balkan-, and Sintashta-Potapovka-related expansions.
4.1. Bell Beakers
The amount of Yamnaya ancestry is probably overestimated among populations where Bell Beakers replaced Corded Ware. A map of Yamnaya ancestry among Bell Beakers gets trickier for the following reasons:
Expanding Repin peoples of Pre-Yamnaya ancestry must have had admixture through exogamy with late Sredni Stog/Proto-Corded Ware peoples during their expansion into the North Pontic area, and Sredni Stog in turn had probably some Pre-Yamnaya admixture, too (although they don’t appear in the simplistic formal stats above). This is supported by the increase of Anatolia farmer ancestry in more western Yamna samples.
Later, Yamnaya admixed through exogamy with Corded Ware-like populations in Central Europe during their expansion. Even samples from the Middle to Upper Danube and around the Lower Rhine will probably show increasing contributions of Steppe_MLBA, at the same time as they show an increasing proportion of EEF-related ancestry.
To complicate things further, the late Corded Ware Espersted family (from ca. 2500 BC or later) shows, in turn, what seems like a recent admixture with Yamnaya vanguard groups, with the sample of highest Yamnaya ancestry being the paternal uncle of other individuals (all of hg. R1a-M417), suggesting that there might have been many similar Central European mating networks from the mid-3rd millennium BC on, of (mainly) Yamnaya-like R1b elites displaying a small proportion of CW-like ancestry admixing through exogamy with Corded Ware-like peoples who already had some Yamnaya ancestry.
NOTE. Terms like “exogamy”, “male-driven migration”, and “sex bias”, are not only based on the Y-chromosome bottlenecks visible in the different cultural expansions since the Palaeolithic. Despite the scarce sampling available in 2017 for analysis of “Steppe ancestry”-related populations, it appeared to show already a male sex bias in Goldberg et al. (2017), and it has been confirmed for Neolithic and Copper Age population movements in Mathieson et al. (2018) – see Supplementary Table 5. The analysis of male-biased expansion of “Steppe ancestry” in CWC Esperstedt and Bell Beaker Germany is, for the reasons stated above, not very useful to distinguish their mutual influence, though.
Based on data from Olalde et al. (2019), Bell Beakers from Germany are the closest sampled ones to expanding East Bell Beakers, and those close to the Rhine – i.e. French, Dutch, and British Beakers in particular – show a clear excess “Steppe ancestry” due to their exogamy with local Corded Ware groups:
Only one 2-way model fits the ancestry in Iberia_CA_Stp with P-value>0.05: Germany_Beaker + Iberia_CA. Finding a Bell Beaker-related group as a plausible source for the introduction of steppe ancestry into Iberia is consistent with the fact that some of the individuals in the Iberia_CA_Stp group were excavated in Bell Beaker associated contexts. Models with Iberia_CA and other Bell Beaker groups such as France_Beaker (P-value=7.31E-06), Netherlands_Beaker (P-value=1.03E-03) and England_Beaker (P-value=4.86E-02) failed, probably because they have slightly higher proportions of steppe ancestry than the true source population.
The exogamy with Corded Ware-like groups in the Lower Rhine Basin seems at this point undeniable, as is the origin of Bell Beakers around the Middle-Upper Danube Basin from Yamnaya Hungary.
To avoid this excess “Steppe ancestry” showing up in the maps, since Bell Beakers from Germany pack the most Yamnaya ancestry among East Bell Beakers outside Hungary (ca. 51.1% “Steppe ancestry”), I equated this maximum with BK_Scotland_Ach (which shows ca. 61.1% “Steppe ancestry”, highest among western Beakers), and applied a simple rule of three for “Steppe ancestry” in Dutch and British Beakers.
NOTE. Formal stats for “Steppe ancestry” in Bell Beaker groups are available in Olalde et al. (2018) supplementary materials (PDF). I didn’t apply this adjustment to Bk_FR groups because of the R1b Bell Beaker sample from the Champagne/Alsace region reported by Samantha Brunel that will pack more Yamnaya ancestry than any other sampled Beaker to date, hence probably driving the Yamnaya ancestry up in French samples.
The most likely outcome in the following years, when Yamnaya and Corded Ware ancestry are investigated separately, is that Yamnaya ancestry will be much lower the farther away from the Middle and Lower Danube region, similar to the case in Iberia, so the map above probably overestimates this component in most Beakers to the north of the Danube. Even the late Hungarian Beaker samples, who pack the highest Yamnaya ancestry (up to 75%) among Beakers, represent likely a back-migration of Moravian Beakers, and will probably show a contribution of Corded Ware ancestry due to the exogamy with local Moravian groups.
Despite this decreasing admixture as Bell Beakers spread westward, the explosive expansion of Yamnaya R1b male lineages (in words of David Reich) and the radical replacement of local ones – whether derived from Corded Ware or Neolithic groups – shows the true extent of the North-West Indo-European expansion in Europe:
There is scarce data on Palaeo-Balkan movements yet, although it is known that:
Yamnaya ancestry appears among Mycenaeans, with the Yamnaya Bulgaria sample being its best current ancestral fit;
Interestingly, Potapovka is the only Corded Ware derived culture that shows good fits for Yamnaya ancestry, despite having replaced Poltavka in the region under the same Corded Ware-like (Abashevo) influence as Sintashta.
Srubnaya ancestry shows a best fit with non-Pre-Yamnaya ancestry, i.e. with different CHG + EHG components – possibly because the more western Potapovka (ancestral to Proto-Srubnaya Pokrovka) also showed good fits for it. Srubnaya shows poor fits for Pre-Yamnaya ancestry probably because Corded Ware-like (Abashevo) genetic influence increased during its formation.
On the other hand, more eastern Corded Ware-derived groups like Sintashta and its more direct offshoot Andronovo show poor fits with this model, too, but their fits are still better than those including Pre-Yamnaya ancestry.
The bottleneck of Proto-Indo-Iranians under R1a-Z93 was not yet complete by the time when the Sintashta-Potapovka-Filatovka community expanded with the Srubna-Andronovo horizon:
At the end of the Afanasevo culture, at least three samples show hg. Q1a2-M25 (ca. 2900-2500 BC), which seemed to point to a resurgence of local lineages, despite continuity of the prototypical Pre-Yamnaya ancestry. On the other hand, Anthony (2019) makes this cryptic statement:
Yamnaya men were almost exclusively R1b, and pre-Yamnaya Eneolithic Volga-Caspian-Caucasus steppe men were principally R1b, with a significant Q1a minority.
Since the only available samples from the Khvalynsk community are R1b (x3), Q1a(x1), and R1a(x1), it seems strange that Anthony would talk about a “significant minority”, unless Q1a will pop up in some more individuals of those ca. 30 new to be published. Because he also mentions I2a2 as appearing in one elite burial, it seems Q1a (like R1a-M459) will not appear under elite kurgans, although it is still possible that hg. Q1a was involved in the expansion of Afanasevo to the east.
Okunevo, which replaced Afanasevo in the Altai region, shows a majority of hg. Q1a2-M25, and at least one Q1a1-B284, but also some R1b-M269 samples proper of Afanasevo, suggesting partial genetic continuity.
NOTE. Other sampled Siberian populations clearly show a variety of Q subclades that likely expanded during the Palaeolithic, such as Baikal EBA samples from Ust’Ida and Shamanka with a majority of Q1a2-M25 (in particular Q1a2-L712), and hg. Q reported from Elunino, Sagsai, Khövsgöl, and also among peoples of the Srubna-Andronovo horizon (the Krasnoyarsk MLBA outlier), and in Karasuk. Q1a-M25 was earlier found in a Baltic hunter-gatherer, which supports a widespread distribution of Q1a2 and Q1a1 in North Eurasia during the Neolithic and Bronze Age.
(…) in contrast to the lack of identifiable admixture from Yamnaya and Afanasievo in the CentralSteppe_EMBA, there is an admixture signal of 10 to 20% Yamnaya and Afanasievo in the Okunevo_EMBA samples, consistent with evidence of western steppe influence. This signal is not seen on the X chromosome (qpAdm P value for admixture on X 0.33 compared to 0.02 for autosomes), suggesting a male-derived admixture, also consistent with the fact that 1 of 10 Okunevo_EMBA males carries a R1b1a2a2 Y chromosome related to those found in western pastoralists. In contrast, there is no evidence of western steppe admixture among the more eastern Baikal region region Bronze Age (~2200 to 1800 BCE) samples.
Haplogroup diversity seems to be common in Iron Age populations all over Eurasia, most likely due to the spread of different types of sociopolitical structures where alliances played a more relevant role in the expansion of peoples. A well-known example of this is the spread of Akozino warrior-traders in the whole Baltic region under a partial N1a-VL29-bottleneck associated with the emerging chiefdom-based systems under the influence of expanding steppe nomads.
Surprisingly, then, Proto-Tocharians from Shirenzigou pack up to 74% Yamnaya ancestry, in spite of the 2,000 years that separate them from the demise of the Afanasevo culture. They show more Yamnaya ancestry than any other population by that time, being thus a sort of Late PIE fossils not only in their archaic dialect, but also in their genetic profile:
The recent intrusion of Corded Ware-like ancestry, as well as the variable admixture with Siberian and East Asian populations, both point to the known intense Old Iranian and Old/Middle Chinese contacts. The scarce Proto-Samoyedic and Proto-Turkic loans in Tocharian suggest a rather loose, probably more distant connection with East Uralic and Altaic peoples from the forest-steppe and steppe areas to the north (read more about external influences on Tocharian).
Interestingly, both R1b samples, MO12 and M15-2 – likely of Asian R1b-PH155 branch – show a best fit for Andronovo/Srubna + Hezhen/Ulchi ancestry, suggesting a likely connection with Iranians to the east of Xinjiang, who later expanded as the Wusun and Kangju. How they might have been related to Huns and Xiongnu individuals, who also show this haplogroup, is yet unknown, although Huns also show hg. R1a-Z93 (probably most R1a-Z2124) and Steppe_MLBA ancestry, earlier associated with expanding Iranian peoples of the Srubna-Andronovo horizon.
All in all, it seems that prehistoric movements explained through the lens of genetic research fit perfectly well the linguistic reconstruction of Proto-Indo-European and Proto-Uralic.
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).
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.
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.
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.
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.
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.
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:
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.
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:
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.
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.
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).
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.
I can think of two reasons why this is important:
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.
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.
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.
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 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?
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:
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:
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).
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:
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.
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.
Researchers involved in the investigation of the Yampil Barrow Complex are taking the opportunity of their latest genetic paper to publish and upload more papers in Academia.edu.

Here are some of them, with interesting excerpts (emphasis mine):
The particular interest in this group stemmed from its specific location within the “Yamnaya cultural-historical entity”: its exposure to Central European Corded ware culture (further as CWC) on the one hand, and discernible contact with communities representing the Globular Amphorae culture (GAC), expanding to the south-east, on the other [e.g. Szmyt 1999; 2000]. The location on the fringes of the north-western variant of the Yamnaya culture (YC) [acc. to Merpert 1974; cf Rassamakin 2013a; 2013b; Rassamakin, Nikolova 2008] opened up an interesting perspective for tracing the transfer of Central European cultural patterns to the North Pontic area, and for determining the specificity of the cultural model of steppe communities, which due to their geographic location seemed somehow predestined for westward expansion.
Podolia kurgans originate from various stages of the Eneolithic and Early bronze ages, and this chronological diversity is reflected in differences in construction of mounds and central graves for which kurgans were originally built (being burials of the “kurgans’ founders”). These oldest burials link with various Eneolithic and YC communities, and the taxonomic attribution of some of the phenomena discussed here poses difficulties. This stems from the nature of the finds, which are sometimes only slightly distinctive and often retrieved from contexts difficult to interpret (e.g. from kurgans damaged to a significant degree). Another reason for the high discordance and ambiguity of opinions lies in the nature of the problem itself, since taxonomic definitions can be no more than proxies for cultural processes which are both fluid and multi-directional. This is particularly evident for phenomena associated with the Eneolithic and the very beginnings of the Bronze Age in steppe and forest-steppe areas [e.g. Rassamakin 2013; Manzura 2016], while later stages (the classic and late YC) are marked by much more regularity in terms of funeral rituals. Funerary behaviours displayed by Eneolithic steppe groups were the outcome of intercultural relationships and often combined elements borrowed from different milieus [e.g. Rassamakin 2008: 215, 216]. One consequence of this is the multitude of approaches to the description of Eneolithic phenomena proposed in the literature, with the controversies the situation creates. This is also true for the Podolia kurgans discussed here, where chronology is relatively easy to interpret while taxonomical attributions are much more difficult. A good example in this context is a recently published complex at Prydnistryanske, which has been linked either with the late Trypilia group of Gordinești [Klochko et al 2015d] or with the Eneolithic steppe formation known as Zhivotilovka-Volchansk [Manzura 2016], or recently with the Bursuceni group [Demcenko 2016].
A distinct feature of Podolia kurgans having YC burials is the multi-phase nature of their mounds, a feature recorded throughout the North Pontic area. It is particularly evident in the cases of sequences of burials (typically two burials) placed in the central parts of kurgans and connected with separate stages of the mound’s construction. In this context, the temporal and cultural relationship between the older and younger burial becomes a very interesting issue. Younger burials typically revealed traits characteristic of the YC complex, while older ones were often different and distinguished by a different shape of the grave pit and sometimes a different arrangement and orientation of the body as well. In the most evident cases, older pits held a body in the extended position, reminiscent of the Postmariupol/ Kvityana tradition (…). In such cases, the older grave often stands out with a funerary tradition diverging from model YC behaviours, in terms of orientation, body position, and constructional features.
Kvitjana and Trypillia
The Pre-Yamnaya (Eneolithic) phase came to be distinguished in kurgan cemeteries from the Podolie region after the discovery of burials in extended position (i.e. of the Kvityana/Postmariupol type) at Ocniţa (Fig 10: 2, 3) [kurgans 6 and 7; Manzura et al 1992] and Tymkove (Fig 10: 1) [Subbotin et al 2000, 84, ris 3: 4]. In all these three cases the burials marked the oldest phase of mound construction, and later YC burials were dug into the central part of the kurgan, which entailed the remodelling and considerable enlargement of the mound. Both the chronological and taxonomic positions of extended burials in the North Pontic area are subjects of debate [e.g. Manzura 2010; Rassamakin 2013; Ivanova 2015, 280-282] (…)
The chronological position of graves with burials in extended position can be narrowed down thanks to stratigraphic observations made in kurgans at Bursuceni, between the Dniester and Prut rivers [Yarovoy 1978]. Graves from this site were younger than the burials representing the Zhivotilovka-Volchansk tradition and older than those linked with the early phase of YC based on a relatively compact series of radiocarbon dates obtained for graves of the Zhivotilovka-Volchansk group, the chronology of burials in extended position can be determined as the very close of the 4th – beginning of the 3rd millennia BC (most likely around 3100-2800 BC).
Early and late Yamna
A model ceremonial-funerary complex created by a YC community is a group of kurgans in Pysarivka village [harat et al 2014: 104-165]. Nine mounds have been explored there, of which eight (1, 3-9) yielded central burials of YC sharing a number of similar features (Fig 13). The deceased were placed in regular, rectangular pits having vertical walls Vykids (mounds of soil extracted while digging grave pits) formed regular narrow walls surrounding each grave, and seem to have been integral elements of sepulchral architecture. Chambers were covered with 5-7 timbers/planks arranged parallel to the grave’s longer axis. Another characteristic element was that of wooden stakes driven symmetrically into the bottom along grave chamber edges, recorded in four cases. The deceased were laid on their backs, in a contracted position with the knees up. The head was as a rule turned to W, with possible deflections towards NW or SW Skeletons bore traces of painting with ochre.
The role of south-eastern connections at the early stage of YC development can also be seen in grave IV/4 at Prydnistryanske. This is indicated by a combined (wood and stone) roof construction involving stela-like slabs, and by the skull of the deceased characteristically painted with red pigment. The absolute date obtained for grave IV/4 (ca 3100-3000 bC) suggests its early provenance [Goslar et al 2015]. The grave was most likely connected with the oldest stage of enlargement of the Eneolithic barrow [Klochko et al 2015].
The middle phase of YC is quite clearly evident in Podolia kurgans, it is marked by burials dug into the existing mounds. These are either single burials inserted into different parts of the mounds, or groups of graves forming arches around a central part. Graves with steps leading to the burial chamber are typical of that stage, and they were wider than those in the centres of kurgans. Chambers were typically roofed with planks or timbers placed perpendicularly to the grave’s longer axis burials on one side and burials on the back but leaning to either side become more numerous, and upper limbs were most often placed in A, G, H, or I arrangements ceramic vessels become more common in graves, including forms indicative of contacts with GAC and CWC milieus.
Based on the anatomical properties of the structure of a human body, the histological structure of the skin and location of the dye used for tattooing, having conducted an analysis of postmortem changes occurring within the skin after death, and having taken into consideration the continuous and regular nature of the pattern on the ulnae of the individual from grave no. 10, an interdisciplinary team of researchers has concluded that there is no possibility of a transfer of tattoo dye from the skin onto the surface of an individual’s bone.
The analysis of two ulnae documented in this article indicates that the patterns were made using tree tar, postmortem and directly onto the skeletonised human remains. The placement of the individual’s ulnae in grave no. 10 (Fig. 10), and the location of patterns on the upper skin surface, that is, on surfaces accessible without changing the arrangement of the body, may suggest that the patterns were created on the skeletonised remains without the need to change their placement in the pit (= in situ).
The present conclusions ought to see the beginning of a wider research programme focused on the analysis of the techniques used to create decorations on bones in “kurgan cultures” communities in the context of the Pontic-Caspian Region.
Foxtail millet caryopses are used to make primarily flour, groats and pancakes [lityńska-zając, wasylikowa 2005: 109]. Grains and flour are easily digestible and as such, they are recommended to infants and the elderly. Grains are also fed to fowl and poultry in Asia, foxtail millet is used to make beer and wine, while in China it is also used for medicinal purposes [Hanelt 2001 (Ed )]. Various dishes and beverages made from broomcorn and foxtail millet caryopses in Eurasia are listed by Sakamoto [1987a]. Detailed ethnobotanical studies of the cultivation, crop processing and food preparation in the Iberian Peninsula were presented by Moreno-Larrazabal et al. .
The geographical area under discussion can be related to historical and ethnographic data indicating the use of grits and groats in the diet. They had been known in the menus of European societies since the ‘pre-agrarian’ times. The isotope finding of millet domination in the diet of middle Dniester Yampil Barrow Complex, complemented by bioarchaeological data from the upper steppe Dniester area (from the similarly ‘early-barrow’ Usatovo group/culture with strongly marked ‘eastern’ civilization influences), makes it reasonable to consider the possibility that already in the prologue of late Eneolithic-Early bronze barrow culture (3300- 2800 BC) development there was a clear dividing line of millet groats use – or millet presence – that is, so-called yagla groats (yagla, yagly = millet in Old Slavic languages).
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):
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.
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.
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).
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):
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.
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.
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) .
So let’s cut to the chase and see where Corded Ware peoples (mainly of R1a-Z645 subclades) got their so-called “steppe admixture” different from that of Yamna. Because, as you might have realized by now, Sredni Stog – and consequently Corded Ware – remains nowadays an undefined (archaeological) mess.
Rassamakin explains it quite well, in the chapter Eneolithic of the Black Sea Steppe; In Levine M., Rassamakin Yu., Kislenko A. and Tatarintseva N., 1999. Late Prehistoric Exploitation of the Eurasian Steppe. McDonald Institute Monographs, University of Cambridge.
NOTE. These are only certain relevant excerpts. The whole chapter is worth a thorough read, whatever position you hold regarding steppe expansions. In fact, he supports the Skelya cultural (macro-)group instead of Khvalynsk-Novodanilovka vs. Sredni Stog, he does not believe in significant expansions from the east (but in local movements and a ‘general evolution’ of Pontic-Caspian steppe cultures to Early Yamna), and offers e.g. the presence of copper and trade from the west (and its poor presence in the east) as an example of the importance of the North Pontic area vis-à-vis Khvalynsk/Repin. Not an interested party in supporting Gimbutas or Anthony, then, if you fear that.
Cultural groups in the North Pontic area
Telegin divided the Sredny Stog culture into three local variants – the Dnepr Culture variant, the Oskol-Donets (Aleksandriya) Culture variant, and the Lower Don (Konstantinovka) Culture variant. He elaborated a periodization based on the evolution of decorative motifs in the pottery assemblages.
At first, the internal contradictions of the Sredny Stog culture were not accorded particular prominence, despite clear intimations of problems when, for example, sites like the settlement of Konstantinovka on the Lower Don, was identified as actually belonging to another, independent culture (Kiyashko 1974). The first real blow to the integrity of the Sredny Stog culture was dealt by Telegin himself, when he removed five Novodanilovka-type sites, and accorded them the status of an independent cultural phenomenon (Telegin 1985a). Until that point, sites of this type had were customarily considered to be within the framework of the late group of Sredny Stog cemeteries, despite having been for long regarded by some as representative of an earlier, independent cultural group (Movsha & Chebotarenko 1969; Zbenovich 1973, 74-5; Gimbutas, Merpert and Danilenko passim). Indeed, it was unclear why these cemeteries had initially been assigned to the Late, rather than the Early, Sredny Stog culture. Now these sites were mechanically stripped out of the one system, but their place in the new system was not clearly defined.
Thus a paradox arose. Sites that had served to a considerable extent as the initial basis for the Sredny Stog culture, for the elaboration of its periodization and chronology, were now accepted as forming the core of an essentially different culture. Because of this, by the mid 1980s, both the Sredny Stog culture and the Eneolithic systematization as a whole were becoming rather amorphous. Essentially, the Sredny Stog culture was associated in the minds of many researchers solely with the settlement site at Dereivka, while they had only a confused and indistinct idea of the nature of early Sredny Stog sites. (…) Ultimately a situation developed where all attempts to view new evidence, new local groups, or even cultures through the prism of the Sredny Stog culture were futile, since researchers were unclear about of the essence of the culture itself, and often qualified themselves in footnotes with references to ‘preCorded Ware’ or ‘Corded Ware’ stages, or by relating their observations back directly to the specific sites of Sredny Stog II or Dereivka.
Thus, in the Middle Eneolithic, a number of independent cultures (Kvityana, Repin, Konstantinovka, and, to some degree, Dereivka, Cernavoda and Lower Mikhailovka) emerged in the region that had in the Early Eneolithic been occupied by the Skelya culture, either as lineal successors to this culture or under its influence. But the principal stimuli in this period were the Tripolye tribes, direct imports from whom reach the southern zone of the Dnepr left bank.
It is apparent that, for all their conceptual differences, if we remove Danilenko’s subdivisions, Telegin’s and Danilenko’s models are identical in terms of site periodization and sequence: first Kvityana, then Sredny Stog II, and finally Dereivka.
The North Pontic area in the Eneolithic (4000-3500 BC)
Tripolye influence is seen most clearly in the development of the Lower Mikhailovka culture and a new burial rite which spread as far as the Molochnaya. Changes are apparent in kurgan architecture; that is, in the construction of stone chambers, sanctuaries comprising upright elements, and ring-shaped ditches (Rassamakin 1990; 1993; 1994; Pleshivenko & Rassamakin 1994 ). Lower Mikhailovka sites in the northwestern Black Sea coast region are known by a whole series of different designations, one of which, as I have already noted above, is ‘the Bessarabian variant of the Cernavoda I culture’ (Manzura 1993).
The formation of the Kvityana culture should be considered both in the context of the development of the Lower Mikhailovka culture, and in terms of the influence of the Sredny Stog II pottery assemblage. The first is manifested in the development of the kurgan ritual itself, with such structural elements as cromlechs, orthostats and stone cists. These are most apparent to the south, in the zone of contact with the Lower Mikhailovka culture. The second is apparent in the similarity between Kvityana pottery and Sredny Stog II pottery, notably in a number of shared compositional and technical elements, despite the fact that the shapes, techniques and style are all quite different.
As a whole, the Kvityana culture is notably conservative and archaic in appearance; this is manifest both in the preservation of a burial rite involving a supine position, and in the appearance of the pottery which, on the basis of the absence of corded or caterpillar track decoration, was until recently considered the earliest Sredny Stog ware.
(…) we still lack sufficient evidence to trace in detail the path by which the Kvityana culture spread from the Dnepr into the Dnestr-Danube region. The southern steppe route is excluded, but Kvityana sites are recorded on the Southern Bug, in the Dnestr region, and even along the forest-steppe boundary on the Prut Gudging by the numerous excavations of kurgans in this belt. This route in some respects repeats that along which the Skelya elite groups moved. Southward movement along the Southern Bug and its tributaries into the steppe zone is indicated only by isolated sites, the number of which is far smaller than in the Dnestr-Danube region, despite the intensive excavation of kurgans in this region. Evidence for Kvityana penetration into the northwestern Black Sea coast is provided by the appearance in Usatovo assemblages of typical Kvityana figural tubular bone beads, with diagnostic lateral notches on the sides (Malyukevich & Petrenko 1993).
[The Dereivka] culture is currently only known only from settlement material, notably from sites in the Dnepr region (Dereivka and Molyukhov Bugor), but also from typologically distinctive pottery in the Eneolithic layer of the settlement of Aleksandriya on the Oskol. Dereivka culture pottery has also been recorded at a number of locations in the forest-steppe Dnepr region and the Seversky Donets, at Tetyanchino, Kamennye Pataki, and Minevsky Yar. The ceramic assemblage is well-defined and easily recognizable: vessels consistently display a weak profile and slightly elongated proportions, with high, straight mouths, evenly cut off at the rim, and conical bases (Fig. 3.23). The Dereivka culture occupies the southern part of the forest-steppe region and is bounded to the south by the Kvityana culture.
Telegin rightly noted that Dereivka and Kvityana pottery bore some resemblance to one another. Several fragments of the latter were found in the Dereivka assemblage, and provide evidence for the contemporaneous existence of the two cultures. The Molyukhov Bugor pottery assemblage stands out in terms of a prevalence of pottery with corded decoration, which only occurs in insignificant amounts at Dereivka and Aleksandriya. However, artefactual analysis has not produced any clear guidance for a chronological organization of these sites, as was postulated by Telegin.
Late Phase and Final Eneolithic (3500-3000 BC)
In the Dnestr region, southward pressure from Tripolye led to the formation of, firstly, Vykhvatinsk-type sites, and then, in the steppe zone, Usatovo-type sites, which had undoubtedly absorbed some features of the Lower Mikhailovka culture. In the Prut and Middle Dnestr regions, sites of the Gordineşti (Kasperovkao) types are formed (these correspond, in the Romanian Prut region and on the Siret, to sites of the Horodiştea-Erbiceni type, and on the Lower Danube to the Cernavoda III culture: Morintz & Roman 1968; Dinu 1980; 1987). Movsha considers that sites of this type (Kasperovkao in her terminology) also occur in the Southern Bug region.
Sofievka-type sites emerge in the forest-steppes of the Middle Dnepr. A number of researchers (Zbenovich, Dergachev, and Sorokin), taking account of the change in the Tripolye culture at stage C2, propose a special division, considering sites of this period alone as ‘Late Tripolye’. In their view (with which I agree), stage Cl in culture-historical terms still corresponds to ‘Middle Tripolye’.
(…) existing evidence allows us to put forward the following scheme (Fig. 3.49:2). To the east of the Usatovo sites, from the lower reaches of the Southern Bug to the Azov region, encroaching on the Crimean steppes, the Lower Mikhailovka culture remains intact. To the north, upstream along the Dnepr and its tributaries, the Kvityana culture survives in its initial core zone. Between the Southern Bug and the Dnepr, in the contact zone between the three cultures (Tripolye, Lower Mikhailovka and Kvityana) the Dnepr-Bug group of sites emerges, displaying mixed features (Nikolova & Rassamakin 1985; Rassamakin 1988) Tripolye influence on the Dereivka culture appears to increase, as manifested in the appearance of late cultural elements (corded decoration, plastic art, bowls). The fate of the Pivikha culture is unclear. On the Lower Don, the late phase of the Konstantinovka culture (corresponding to the settlements of Konstantinovka and Razdorskoe I: Level 7) continued.
The final stage
The final stage of this period is characterized by two waves of migration, which properly speaking conclude the development of the Eneolithic.(…)
The first migration is connected with the breakdown of that system of Late Tripolye forest-steppe sites of the Prut-Dnestr and Southern Bug regions, dealt with by Movsha within the framework of the Kasperovo local group (and termed Gordineşti by others such as Dergachev, Manzura, and Petrenko). Almost all researchers into the Tripolye culture note the widespread occurrence of diagnostic elements of this group in the south, in the zone of the Usatovo sites and, in the east and southeast, towards the Dnepr and its left bank (Movsha 1984; 1990; 1993; Subbotin & Petrenko 1986; Manzura 1990a). (…)
The migrational wave that left Zhivotilovo-Volchanskoe-type burials in the steppe also linked up the forest-steppe Bug, Dnestr, and Prut regions with the Lower Don region, and, possibly with the North Caucasus, where the late stage of the Maikop culture (the Novosvobodnaya sites) continued. The identical rites of the Maikop culture and Zhivotilovo-Volchanskoe sites makes it difficult to establish the direction of migration, or which was the active side in the process. A number of researchers have given precedence to the Maikop culture. But the spread of the Tripolye assemblage unambiguously indicates the active involvement of the Tripolye tribes.
The second migration, at the very end of the Eneolithic, is connected with the spread of the Repin culture (in its second phase) from the Middle Don. Sinyuk defined three main directions: north, to the Upper Don; southwest, into the Dnepr region; and south, to the Lower Don and the Lower Volga. Trifonov considers this broad expansion of the Repin culture to be colonization (Trifonov 1996). The Repin culture level at Razdorskoe I (Razdorskoe I: Level 8) overlies the Konstantinovka levels (Levels 6 and 7), signalling that the Konstantinovka culture had apparently ceased to exist (Kiyashko 1994, 80). It seems that the expansion of the Repin culture is also associated with a reduction in the territorial extent of the Kvityana and Dereivka cultures. Repin burial assemblages, settlements and temporary camps appear in the Seversky Donets basin and in the Eastern Azov region (at Trekhizbenka, Kapitanovo, Aleksandriya, and Razdolnoe). The same complexes are also widely distributed towards the Dnepr (Marina 1992). The most striking western manifestation of Repin elements is seen in the upper horizon of the middle level of the Mikhailovka settlement (Lagodovska et al. 1962, 39-46).
Khvalynsk-Yamna and Sredni Stog-Corded Ware
We already know that Ukraine Eneolithic samples showed steppe ancestry and had apparently began a process of convergence coinciding with (or after) the first Khvalynsk-related migrations. It is unclear what had happened before (i.e. how much “CHG ancestry” was absorbed by Ukraine Neolithic groups in their transition to the Eneolithic before ca. 4500 BC), although in principle we can assume that all Caucasus-related admixture received by North Pontic cultures ca. 4500-4000 BC was mediated by westward movements from Khvalynsk-related peoples.
Contacts with (and later absorption of) Khvalynsk-Novodanilovka-related migrants, as well as heir cultures, like those in the steppe adjacent to the Black Sea coast, and also direct contacts with Caucasus-related populations through Zhivotilovo-Volchanskoe can justify a greater contribution of CHG ancestry ca. 4000-3500 BC. Close contacts with Cucuteni-Trypillia (through Mikhailovka and maybe Kvityana, possibly with WHG and CHG admixture related to Khvalynsk-Novodanilovka) and GAC peoples to the north are the obvious source of further similarities with Yamna. Distinct similarities, that is, if we take into account the different sources and timing of such ancestral components, and Y-chromosome bottlenecks…
Therefore, after a process of convergence ca. 4500-4000 BC, and potentially more contacts with late Eneolithic North Pontic steppe cultures ca. 4000-3500 BC, Proto-Corded Ware peoples must have finally spread from the northernmost (forest-steppe) areas previously occupied by Dereivka, Pivikha, or Sofievka groups from ca. 3300 BC onwards – a date roughly coincident with the expansion of late Khvalynsk/Repin to the west developing the Early Yamna culture, with which it likely entered in contact (hence potentially a source for further admixture convergence ca. 3500-3000 BC).
Only later happened the great migration ca. 3000-2800 BC of Classical Corded Ware culture migrants, at the same time as Early Yamna migrants expanded to the west, and some groups also to the north along the Prut (possibly directly connected to the admixture found in the two Baltic LN/CWC ‘outliers’).
We didn’t know much about Sredni Stog or Corded Ware, and we still don’t. I can’t see the future, and I don’t have access to information from Reich-Jena or Copenhagen groups, and never have. But I just don’t see the need to explain Corded Ware as derived from (coeval) Early Yamna, and I haven’t since the 2015 papers. It was not the best explanation for the data that was published, and the more information we receive, the less sense this theory makes.
However, I guess we will see some groups still resorting to the good old Yamnaya ancestral component™ = Indo-European no matter what, consciously ignoring that a proportion of ancestral components (some combination of EHG:CHG:WHG in this case) means nothing without a proper explanation of their precise temporal and regional origin, and how they connect with Yamna; just like the CHG ancestry = Indo-European trend we are living right now does not make any sense.
Publishing only selected results after trying every possible combination of samples with bioinformatic tools does not help strengthen this connection, either.
The concept of ‘Kurgan peoples’ is a general idea whereby ‘kurgan builders’ are identified with Indo-European speakers. It is a consequence of the oversimplification of Gimbutas’ theory, and is still widespread among linguists, archaeologists, geneticists, and amateurs alike.
NOTE. On the already simplistic assumptions of Gimbutas regarding the so-called ‘kurgan’ burials, see e.g. Häusler’s early criticism.
However, as more ancient DNA studies appear, many ancient cultures once held as ‘kurganized’ are becoming more and more clearly disconnected from Proto-Indo-Europeans: So for example Varna, Cucuteni-Trypillia, Maykop, or Northern Iranian kurgan builders.
NOTE. As you may know, Rassamakin supports a ‘Skelyan’ (macro-)culture encompassing every group from the North Pontic steppe and steppe-forest, where (therefore) Novodanilovka or Suvorovo would be just rich elites among Sredni Stog and related ‘commoners’. So he can hardly be described as interested in supporting Khvalynsk over Sredni Stog influence…
The first period of development (ca. 4550 – 4100/4000 BC) is marked as a period of emergence of the first burial symbols.
Gimbutas – like later her pupil Mallory -, Merpert, or Danilenko believed that the first mark of emerging kurgans were precisely the presence of constructions above burials, such as simple, small, stone henges, dolmens, cists, or cairns. Hence the traditional connection of ‘kurgans’ with Sredni Stog. This Sredni Stog connection is currently still a widespread belief, that is kept alive because it appears in many secondary sources (e.g. the much beloved as it is outdated and simplistic reference book Encyclopedia of Indo-European Culture).
These first constructions described as from Sredni Stog were nevertheless found solely among Sredni Stog ‘elites’. That is, burials from Novodanlilovka-type cultural sites. So, following the initial assessments of this culture by Soviet archaeologists (like Telegin), for Gimbutas (1956) they were among ‘Sredni Stog’ burials, and for Merpert (1959) they might have been due to an “initial, genetic basis” originally from Khvalynsk, and thus (what was described as) Sredni Stog seemed to have been formed under “strong eastern influences”.
NOTE. From Rassamakin’s own account: Gimbutas’ model was later corrected, when in the mid-1980s Telegin judged that the cemeteries in fact represented an independent cultural type (Novodanilovka-type sites), developing over two stages (Telegin 1985a, 311-20; 1991). These were the same burials which Danilenko thought reflected a distinct pastoralist culture among the early Yamnaya tribes, which Gimbutas attributed to the first kurgan wave, and which Merpert, in part, ascribed to the first chronological period of the early Yamnaya culture-historical province.
These early constructions, however, are not found anywhere else in the North Pontic region except for those ‘Sredni Stog elites’:
Rooves made from separate slabs with cairns are known in the Dnieper and Volga regions: In the Khvalynsk I culture, 17% of burials were superimposed with stone cairns or had a single stone marker.
Cists with cairns are known from Severskii Donets and Azov areas.
A unique cromlech is described from the Dniester-Danube area (Suvorovo).
In the remaining cases, especially for the Volga area and pre-Caucasus steppe, there are some specific variants:
Use of natural hills as a burial marker
Presence of smalll earthen or wooden constructions.
If we accept that these constructions are the first rudimentary kurgans or proto-kurgans, and that kurgans were a mark of expanding Indo-European culture, let’s see who built them first and why:
The emergence of kurgans
In his book Рождение Кургана (2012), The Emergence of the Kurgan, Sergei Korenevskiy makes a thorough analysis of the first kurgan finds.
The Novodanilovka group (ca. 4500-4000 BC), coincident with the Trypillia B1 stage, is characterized by the presence of ochre (in great quantity) in burials, as seen in Khvalynsk, as well as stone constructions in burials.
NOTE. Similarly to Rassamakin, Korenevskiy believes in the unity of North Pontic cultures, and specifically of Novodanilovka chiefs among Sredni Stog commoners, and of all of them with Khvalynsk in a Khvalynsk-Sredni Stog cultural-historical region, because of their “chronological and regional coincidence” and similar pottery, in spite of differences in burial and symbolism. So, hardly an interested party in supporting the expansion of Khvalynsk to the west, either.
Obviously, for those of us who believe that symbolism and burials do mean something beyond similar pottery decoration, in the instances where Sredni Stog appears in his text, it should be read Novodanilovka (and Khvalynsk-Sredni Stog should be read Khvalynsk-Novodanilovka) instead; because he is not referring to the older Khvalynsk – Sredni Stog community of the beginning of the 5th millennium, but to a very distinct group of sites related to the Khvalynsk expansion with horse symbolism at the end of the 5th millenium.
For the early Eneolithic time and the existence of the Khvalynsk-Sredni Stog community, on the problem under consideration, the main source [of knowledge for the first kurgans] may be the Nalchik and Khvalynsk burial grounds.
The kurgans themselves were not simple pits filled with earth. There was a belief that the funerary structure was the place where the buried moved to another world. Most likely, such a place could be considered to be a generic collective cemetery.
The second important point may be that the Eneolithic era was the time of development of a prestigious economy that created its values in the form of different things. Among them were items requiring high skills or manufacturing techniques (different woolen tools, scepters, stone bracelets), as well as tools that occupy an important role in labor, war and industry (stone flat axes, arrowheads, knife-like plates and chips of flint). The decorations of the burial costume included certain iconic objects – bone plates from canine fang, pins, bone sticks with a hole- “zurki”).
Presented were a variety of beads from bone, stone, shell. Bead washers could be collected in whole garlands, thus acquiring a special value. Prestigious cult things, presumably, were copper jewelry: beads, rings, bracelets. They, like the shells, were products of the gift exchange and reflected the direct or indirect involvement of the owners.
Khvalynsk and Nalchik first marked burials
[The Nalchik burials:] with respect to the reconstruction of social relations, data are few. In general, the funerary practice of this necropolis does not reflect the position of any fighting tools in the grave. (…)
Judging by the rare ornaments from the burials of the necropolis, the population that left it was implicated in the prestigious values of the Khvalynsk-Sredni Stog community. A more detailed picture of the era of early Eneolithic reflects the data of the Khvalynsk-type burial ground.
(…) the Khvalynsk burial ground was characterized by a system of age groups and a forming social structure based on the hierarchy of estate groups. The social organization of Khvalynians can be characterized by the stage of evolution of a small-family variant of the development of a primitive society, in which the social status of a man and a woman became closer. The role of the married woman / mother was accentuated. Archaeological signs of this process can be considered joint burials of old people and children and as part of burials with same and mixed genders.
In summary, one can arrive at the following conclusions. It is unlikely to be a mistake if we assume that the Khvalynsk burial ground was abandoned by a local community that lived on the basis of the tribal collective. Their economic activities were connected with hunting, fishing, homestead cattle breeding with an obvious acquaintance with the horse (it is not known if the object of hunting or domestication). In the mythology of the afterlife and the funerary traditions of the Khvalynians, the same egalitarianism of the forms of funerary buildings was dominant, but signs of the personification of graves began to appear, with marks in the rarest of cases with stones.
Unlike the Nalchik cemetery, in the Khvalynsk and Khlopkovsky burial grounds, new trends in assessments of the suitability of implements for funerary practice are clearly discernible. So, they expressed themselves in the appearance of rare graves with scepters, axes – buggers, stone adzes, harpoons and fishing hooks. Basically, all these symbols of the rite are associated with male burials. The least saturated with burial items with stone adzes, and they are represented in small forms. But the fact is important. Society began to pay attention to these categories of objects, linking their symbols with mythological ideas about the things of the afterlife and their functions in the “other dimension of reality” specifically as tools of war and symbols of military power or valor (axes with trunnions), spiritual power (scepters), as well as woodworking (adzes). In terms of “wealth”, these complexes were not particularly distinguished from other inventory sets.
The population that left the Khvalynsk burial ground had to do with the deficit of the era, which was copper products. The latter emphasized, apparently, the age status of some men from 40 to 60 years old and adult women. Another scarce raw material could be a sea shell (item 38) from the burial of a man aged 25-35 years.
As a result, it can be concluded that the complexes of funerary ritual of the Khvalynsk burial ground indicate the existence of ideas about a person at the time of his transition to another world, as a member of the collective of the clan (community) with the admitted individual prestige of things that emphasize his age or social status, but in the framework of the common egalitarian tradition of a collective necropolis. At this time, presumably, views were developing on the relationship of the things put in the grave with the “property” of the buried.
The aftermath of the kurgan expansion
The most important phenomenon in the Weltanschauung of the late Eneolithic population in the steppes of Eastern Europe and Ciscaucasia was the spread of the religious tradition, relatively new in comparison with the time of the Mariupol cultural and historical community, according to which the deceased began to go to another world in a position on his back, crocheted, in the company of ochre magic.
This position appears to be dominant in the materials of the Khvalynsk cemetery, and as a very significant – but not dominant – feature of the materials of the Nalchik cemetery. The posture on the back is crocheted, becoming typical for the Sredni Stog culture, as well as the bearers of the oldest Kurgan traditions in the Ciscaucasia and the Volga-Don region.
Our position on this issue is as follows. I can fully adhere to the opinion of B. Govedaritsa and I.V. Manzura that the transition of the population of the Khvalynsk – Sredni Stog community to the tradition of the burial crouched on their backs looks like the most important ideological innovation in the mythology of death among the local population of Eastern Europe and Ciscaucasia in relation to the earlier time of the Mariupol cultural and historical community.
In the funerary practice of this cultural education there is much in common with the traditions of the funerary practice of the Balkan-Danube region. At the same time, the posture pose on the back is spread more widely in the Neolithic and Eneolithic than only Western Europe. It was recorded in the necropolis of Kul-Tepe I in Azerbaijan (Abibulaev, 1982), the necropolis of Tepe Gissar in Iran (Schmidt, 1933, 1937), in burials 1, 2 in the settlement of Poylu II of Leleatepin culture in Azerbaijan (the Kura valley) (Museibli , 2010. P. 208). In other words, it is the same universal way of inhumation, like a pose on one side or a burial on the back, although not so widespread on a global scale.
From where and how such ritualism could appear in its specific carriers, it definitely cannot always be established. But let us pay attention to the fact that the peculiarity of the posture of the deceased population of the Khvalynsk – Sredni Stog community on the back is that the deceased was not simply placed on his back, he was often heavily sprinkled with ochre. The last detail of the ritual clearly has a prototype for the carriers of the Mariupol community of the Northern Black Sea Region. This suggests that such funerary practice of the Khvalynsk – Sredni Stog community was formed on the spot, as an internal transformation of the ritual of a stretched-out body with a copious sprinkling of the bone with mineral red paint. The idea of innovation was to set the feet on the ground, which caused the knees to rise.
The consequence for the Proto-Indo-European homeland
So, from now on, when someone says “the oldest known kurgans come from Sredni Stog”, you know what that means: first, these are not the oldest ‘kurgans’, but rather ‘proto-kurgans’ (after, all, some of the first radiocarbon dates of full fledged steppe kurgans come from the Repin culture, if we don’t take the rich Maykop variant into account); and second, they were not really from Sredni Stog, but from Khvalynsk-related cultures, because the first rudimentary kurgans can be clearly traced back to Khvalynsk, Novodanilovka, Northern-Caucasus, and Suvorovo sites.
The latest genetic research on Khvalynsk- and Yamna-related migrations should have been a party for all involved in a quest to know the truth about Proto-Indo-Europeans, as it is becoming clear that their language and culture expanded from the eastern Pontic-Caspian steppe. This is a short checklist of relevant facts:
✅ Khvalynsk formed from EHG + local steppe Neolithic groups: checked.
✅ Kurgan origins and expansion from Khvalynsk: checked.
✅ Expansion of horse domestication and horse symbolism from Khvalynsk: checked.
✅ Arrival of steppe ancestry in the Balkans with Suvorovo: checked.
✅ Expansion of Khvalynsk as Early Yamna and Afanasevo: checked.
✅ Expansion of Yamna Hungary as East Bell Beakers: checked.
✅ Y-DNA bottlenecks of expanding Bell Beakers: checked.
✅ Expansion of East Yamna (and admixture with CWC) in Sintashta/Potapovka: checked.
✅ Y-DNA bottlenecks of expanding Andronovo/Srubna: checked.
✅ Yamna in the Balkans and steppe ancestry in Mycenaeans (in contrast with Minoans): checked.
✅ Bell Beaker expansion over Europe and later resurge of R1a-Z645 in Central-East Europe: checked.
All this combined is giving a clear-cut image of how Proto-Indo-Europeans expanded. More importantly, it shows – as I have said many times already – that Proto-Indo-European was a real language, spoken by an evolving and expanding community (with radical language changes beautifully coupled with archaeological expansions). The implications of this are huge, if only because we can finally get rid of all naysayers in linguistics and archaeology, who wanted to speak about ‘constellations of languages’ and ‘pots not people’.
So why would some of those who describe themselves as interested in Prehistory not accept this as the most likely picture right now? I can just think of one tiny item of the checklist, among many that are left unchecked or have been unchecked due to the latest genetic research:
❌ ‘MY haplogroup’ was involved in the expansion of ‘MY people’: Unchecked.
It is not just that this isn’t checked. It was checked by many in the 1990s and in the 2000s, and some stupid magical meaning was attributed to it. But now it has been unchecked for most Europeans, and this has caused an absurd unrest among some of them, who are now joining those who already opposed mainstream theories (e.g. supporters of the Anatolian homeland, the Iran homeland, the Indus Valley homeland, etc.) with a common aim: to spread reactionary views against the mainstream theories.
If all samples from Khvalynsk, Yamna, Afanasevo, and Bell Beaker had been R1a-Z645; most European Neolithic samples had shown R1b-L23 subclades; and results from Sredni Stog, Corded Ware and part of the Indo-Iranian community were of haplogroup N1c-L392 (although eventually R1a-Z645 had expanded with Indo-Iranians)… Would these people doubt all those facts from the checklist? I don’t think so.
Interesting excerpts (only introduction and conclusions, emphasis mine):
Archaeological setting at the site of Maidanetske, Ukraine
From ca. 4800 to 3350 BCE, Trypillia settlements were widespread over parts of eastern Romania, Moldova and Ukraine (Menotti and Korvin-Piotrovskiy, 2012; Müller et al., 2016; Videiko, 2004). Maidanetske (Fig. 1B) is one of the so-called “mega-sites” which developed during ca. 3900–3400 BCE in central Ukraine, in the Uman region (Cherkasy district) (Müller and Videiko, 2016; Müller et al., 2017). In this region, nine of these “mega-sites” have been found. Mega-sites are characterized by a regular plan with concentric rings of houses around a large empty central space, additional quartiers, with radial and peripheral track ways (Fig. 1B). The three mega-sites Maidanetske, Taljanky and Dobrovody, lay ca. 15 km apart from each other (Fig. 1A); other mega-sites are located within a 50 km radius around Maidanetske. Archaeologically, these mega-sites consist of the remains of buildings most of them burnt, although a minority of unburnt buildings is known of as well (Burdo and Videiko, 2016; Müller and Videiko, 2016; Ohlrau, 2015). Most of these buildings have a standardized regular size (average 6×12 m) and architecture including domestic installations and a standardized assemblage of artifacts. At Maidanetske beside normal sized houses there are few larger rectangular buildings that are located regularly along the main pathways. Further archaeological contexts include pits, pottery kilns, and peripheral ditches. A huge variety of mostly painted pottery (including many with figurative animal and plant motives), some flint artifacts, rare copper objects, querns, adzes and a broad range of anthropomorphic and zoomorphic figurines are attested within houses and mega-structures. In terms of organic remains, animal bones are fairly common, while botanical macro-remains appear to be scarce and poorly preserved (Kirleis and Dal Corso, 2016; Pashkevich and Videjko, 2006).
Environmental setting at Maidanetske
The Trypillia sites in central Ukraine, including Maidanetske, are located in a semi-arid forest-steppe ecozone, a mosaic-like ecosystem stretched between the dry steppe grasslands in the south and temperate woodland biomes in the north (Fig. 1A). In this transitional zone the natural vegetation is supposed to be patchy and sensitive to climate and topography (Feurdean et al., 2015; Molnàr et al., 2012; Walter, 1974). Since most of the accessible plateaus are converted to agricultural land and the scarce broadleaf woodlands are managed, the natural landscape heterogeneity is difficult to trace within the current landscape (Kuzemko et al., 2014). Besides agricultural fields and villages, narrow river valleys incised into the loess plateaus are present, with riparian vegetation and artificial lakes. This western Pontic area has a humid continental climate with wet winters and warm summers (Köppen and Geiger, 1939), which corresponds to a semi-arid 0.2–0.5 aridity index value according to UNEP (1997). Nevertheless, the reconstruction of past climatic as well as environmental conditions is not straightforward, since undisturbed archives for pollen analysis are lacking in the region and published climatic reconstructions combine evidences from peripheral areas (Gerasimenko, 1997; Harper, 2017; Kirleis and Dreibrodt, 2016). In the Transylvanian forest-steppe region, palynological investigations suggest that dry grasslands have expanded since the end of the 4th millennium BCE, fostered by Bronze Age forest clearance, while before this the area was largely forested (Feurdean et al., 2015). In the Hungarian forest-steppe, the mixed oak forest on Loess almost disappeared by the end of the 18th century AD, hampered by factors such as fragmentation, slow regeneration, spread of invasive species and lowering of the water table due to increased aridity (Molnàr et al., 2012). It is clear that forest-steppe environments are very sensitive to aridity and land use practices. To understand whether similar landscape change can have occurred in central Ukraine already at the time of Chalcolithic mega-sites, an understanding of the extent of crop growing and deforestation is crucial.
The site of Maidanetske is situated on a plateau covered by Loess deposited during the Last Glaciation. This plateau is dissected by valleys of different sizes with perennial rivers present within the large valleys. One of these rivers passes the site in a distance of less than 500 m. The soils that are present nowadays are Chernozems. They show dark greyish-brown A-horizons of thicknesses between 30 and 50 cm and a texture dominated by silt. Numerous filled crotowinas indicate an intensive bioturbation during the formation of these soils. The Chernozems cover the archaeological record. The variations in thickness of the A-horizon are probably reflecting post-depositional soil erosion processes. Buried soils discovered at lower slope positions below colluvial layers show properties of Cambisols, thus pointing towards a forested past of the surrounding landscape (Kirleis and Dreibrodt, 2016).
At the site of Maidanetske, the phytolith record from different contexts including multiple houses, was studied, which confirmed cereal cultivation as part of the subsistence economy of the site. Furthermore, phytoliths gave information about wild grasses, whereas dicotyledonous material was scarce. For the house structures cereal byproducts, chaff and straw were identified as material selected for tempering daub for the wall construction. Ash layers in a pit filled with house remains show similar pattern. Daub fragments and pit filling are the most promising archives for further phytolith work on cereals at Trypillia sites. The sediment inside four burnt houses and the areas outside two houses, where also grinding stones were sampled, showed little presence of the remains of final cereal processing, suggesting that either the surfaces were cleaned and the chaff was collected after dehusking, or the cereal processing activity took place somewhere else. Specific archaeological contexts, such as vessels and grinding stones, did not differ much from the control samples from archaeological sediment nearby, suggesting disturbance of the record.(…)
