A very “Yamnaya-like” East Bell Beaker from France, probably R1b-L151

bell-beaker-expansion

Interesting report by Bernard Sécher on Anthrogenica, about the Ph.D. thesis of Samantha Brunel from Institut Jacques Monod, Paris, Paléogénomique des dynamiques des populations humaines sur le territoire Français entre 7000 et 2000 (2018).

NOTE. You can visit Bernard Sécher’s blog on genetic genealogy.

A summary from user Jool, who was there, translated into English by Sécher (slight changes to translation, and emphasis mine):

They have a good hundred samples from the North, Alsace and the Mediterranean coast, from the Mesolithic to the Iron Age.

There is no major surprise compared to the rest of Europe. On the PCA plot, the Mesolithic are with the WHG, the early Neolithics with the first farmers close to the Anatolians. Then there is a small resurgence of hunter-gatherers that moves the Middle Neolithics a little closer to the WHGs.

From the Bronze Age, they have 5 samples with autosomal DNA, all in Bell Beaker archaeological context, which are very spread on the PCA. A sample very high, close to the Yamnaya, a little above the Corded Ware, two samples right in the Central European Bell Beakers, a fairly low just above the Neolithic package, and one last full in the package. The most salient point was that the Y chromosomes of their 12 Bronze Age samples (all Bell Beakers) are all R1b, whereas there was no R1b in the Neolithic samples.

Finally they have samples of the Iron Age that are collected on the PCA plot close to the Bronze Age samples. They could not determine if there is continuity with the Bronze Age, or a partial replacement by a genetically close population.

PCA-caucasus-yamna
Image modified from Wang et al. (2018). Samples projected in PCA of 84 modern-day West Eurasian populations (open symbols). Previously known clusters have been marked and referenced. Marked and labelled are interesting samples; In red, likely position of late Yamna Hungary / early East Bell Beakers An EHG and a Caucasus ‘clouds’ have been drawn, leaving Pontic-Caspian steppe and derived groups between them. See the original file here. To understand the drawn potential Caucasus Mesolithic cluster, see above the PCA from Lazaridis et al. (2018).

The sample with likely high “steppe ancestry“, clustering closely to Yamna (more than Corded Ware samples) is then probably an early East Bell Beaker individual, probably from Alsace, or maybe close to the Rhine Delta in the north, rather than from the south, since we already have samples from southern France from Olalde et al. (2018) with high Neolithic ancestry, and samples from the Rhine with elevated steppe ancestry, but not that much.

This specific sample, if confirmed as one of those reported as R1b (then likely R1b-L151), as it seems from the wording of the summary, is key because it would finally link Yamna to East Bell Beaker through Yamna Hungary, all of them very “Yamnaya-like”, and therefore R1b-L151 (hence also R1b-L51) directly to the steppe, and not only to the Carpathian Basin (that is, until we have samples from late Repin or West Yamna…)

NOTE. The only alternative explanation for such elevated steppe ancestry would be an admixture between a ‘less Yamnaya-like’ East Bell Beaker + a Central European Corded Ware sample like the Esperstedt outlier + drift, but I don’t think that alternative is the best explanation of its position in the PCA closer to Yamna in any of the infinite parallel universes, so… Also, the sample from Esperstedt is clearly a late outlier likely influenced by Yamna vanguard settlers from Hungary, not the other way round…

Unexpectedly, then, fully Yamnaya-like individuals are found not only in Yamna Hungary ca. 3000-2500 BC, but also among expanding East Bell Beakers later than 2500 BC. This leaves us with unexplained, not-at-all-Yamnaya-like early Corded Ware samples from ca. 2900 BC on. An explanation based on admixture with locals seems unlikely, seeing how Corded Ware peoples continue a north Pontic cluster, being thus different from Yamna and their ancestors since the Neolithic; and how they remained that way for a long time, up to Sintashta, Srubna, Andronovo, and even later samples… A different, non-Indo-European community it is, then.

Different Bell Beaker clines have been drawn, to represent approximate source of expansions from Central European sources into the different regions. In red, likely zone of Yamna Hungary and reported early East Bell Beaker individual from France.

Let’s wait and see the Ph.D. thesis, when it’s published, and keep observing in the meantime the absurd reactions of denial, anger, bargaining, and depression (stages of grief) among BBC/R1b=Vasconic and CWC/R1a=Indo-European fans, as if they had lost something (?). Maybe one of these reactions is actually the key to changing reality and going back to the 2000s, who knows…

Genetic landscape and past admixture of modern Slovenians

slovenes-snp

Open access Genetic Landscape of Slovenians: Past Admixture and Natural Selection Pattern, by Maisano Delser et al. Front. Genet. (2018).

Interesting excerpts (emphasis mine):

Samples

Overall, 96 samples ranging from Slovenian littoral to Lower Styria were genotyped for 713,599 markers using the OmniExpress 24-V1 BeadChips (Figure 1), genetic data were obtained from Esko et al. (2013). After removing related individuals, 92 samples were left. The Slovenian dataset has been subsequently merged with the Human Origin dataset (Lazaridis et al., 2016) for a total of 2163 individuals.

Y chromosome

First, Y chromosome genetic diversity was assessed. A total of 52 Y chromosomes were analyzed for 195 SNPs. The majority of individuals (25, 48.1%) belong to the haplogroup R1a1a1a (R-M417) while the second major haplogroup is represented by R1b (R-M343) including 15 individuals (28.8%). Twelve samples are assigned to haplogroup I (I M170): five and two samples belong to haplogroup I2a (I L460) and I1 (I M253), respectively, while the remaining five samples did not have enough information to be further assigned.

pca-slovenes
PCA of Slovenian samples with European populations (Slovenian_HO_EU dataset). For details regarding the populations included, see Supplementary Table 1.

PCA

Considering the unbalanced sample size of the Slovenian population compared to the other populations included in the dataset, a subset of 20 Slovenian individuals randomly sampled was used.

All Slovenian samples group together with Hungarians, Czechs, and some Croatians (“Central-Eastern European” cluster) as also suggested by the PCA. All Basque individuals with few French and Spanish cluster together (“Basque” cluster) while a “Northern-European” cluster is made of the majority of French, English, Icelanders, Norwegians, and Orcadians. Five populations contributed to the “Eastern-European” cluster including Belarusians, Estonians, Lithuanians, Mordovians, and Russians. Western and South Europe is split into two cluster: the first (“Western European” cluster) includes all Spanish individuals, few French, and some Italians (North Italy) while the second (“Southern-European” cluster) groups Sicilians, Greeks, some Croatians, Romanians, and some Italians (North Italy).

Admixture Pattern and Migration

admixture-slovenians
Modified image, from the paper (Central-East Europeans marked). Unsupervised admixture analysis of Slovenians. Results for K = 5 are showed as it represents the lowest cross-validation error. Slovenian samples show an admixture pattern similar to the neighboring populations such as Croatians and Hungarians. The major ancestral components are: the blue one which is shared with Lithuanians and Russians, followed by the dark green one that is mostly present in Greek samples and the light blue which characterizes Orcadians and English. For population acronyms see Supplementary Table 1.

All Slovenian individuals share common pattern of genetic ancestry, as revealed by ADMIXTURE analysis. The three major ancestry components are the North East and North West European ones (light blue and dark blue, respectively, Figure 3), followed by a South European one (dark green, Figure 3). Contribution from the Sardinians and Basque are present in negligible amount. The admixture pattern of Slovenians mimics the one suggested by the neighboring Eastern European populations, but it is different from the pattern suggested by North Italian populations even though they are geographically close.

Using ALDER, the most significant admixture event was obtained with Russians and Sardinians as source populations and it happened 135 ± 9.31 generations ago (Z-score = 11.54). (…) When tested for multiple admixture events (MALDER), we obtained evidence for one admixture event 165.391 ± 17.1918 generations ago corresponding to ∼2620 BCE (CI: 3101–2139) considering a generation time of 28 years (Figure 4), with Kalmyk and Sardinians as sources.

We then modeled the Slovenian population as target of admixture of ancient individuals from Haak et al. (2015) while computing the f3(Ancient 1, Ancient 2, Slovenian) statistic. The most significant signal was obtained with Yamnaya and HungaryGamba_EN (Z-score = -10.66), followed by MA1 with LBK_EN (Z-score -9.7) and Yamnaya with Stuttgart (Z-score = -8.6) used as possible source populations (Supplementary Figure 5).

We found a significant signal of admixture by using both pairs as ancient sources. Specifically, for the pair Yamnaya and Hungary_EN the admixture event is dated at 134.38 ± 23.69 generations ago (Z-score = 5.26, p-value of 1.5e-07) while for Yamnaya and LBK_EN at 153.65 ± 22.19 generations ago (Z-score = 6.92, p-value 4.4e-12). Outgroup f3 with Yamnaya put Slovenian population close to Hungarians, Czechs, and English, indicating a similar shared drift between these population with the Steppe populations (Supplementary Figure 6).

admixture-events-slovenes
Admixture events identified with ALDER and MALDER. The gray dots represent significant admixture events detected with ALDER using Slovenians as target, the solid line represents the single admixture event detected using MALDER, dashed lines represent the confidence interval. Only the significant results after multiple testing correction are plotted. For ALDER results see Supplementary Table 5.

Not that any of this would come as a surprise, but:

  • R1a-M458 and some R1a-Z280 (xR1a-Z92) lineages (found among Slovenes) were associated with the Slavic expansion, likely with the Prague-Korchak culture, originally stemming probably from peoples of the Lusatian culture. Other R1a-Z280 lineages remained associated with Uralic peoples, and some became Slavicized only recently.
  • PCA keeps supporting the common cluster of certain West, South, and East Slavs in a “Central-Eastern European” cluster, distinct from the “North-Eastern European” cluster formed by modern Finno-Ugrians, as well as ancient Finno-Ugrians of north-eastern Europe who were only recently Slavicized.
  • Admixture supports the same ancient ‘western’ (a core West+South+East Slavic) cluster, and the admixture event with Yamna + Hungary_EN is logically a proxy for Yamna Hungary being at the core of ancestral Central-East population movements related to Bell Beakers in the mid- to late 3rd millennium.

The theory that East Slavs are at the core of the Slavic expansion makes no sense, in terms of archaeology (see Florin Curta’s dismissal of those recent eastern ‘Slavic’ finds, his commentary on 19th century Pan-Slavic crap, or his book on Slavic migrations), in terms of ancient DNA (the earliest Slavs sampled cluster with modern West Slavs, distant from the steppe cluster, unlike Finno-Ugrians), or in terms of modern DNA.

I don’t know where exactly this impulse for the theory of Russia being the cradle of Slavs comes from today (although there are some obvious political trends to revive 19th c. ideas), but it was always clear for everyone, including Russians, that East Slavs had migrated to the east and north and assimilated indigenous Finno-Ugrians, apart from Turkic-, Iranian-, and Caucasian-speaking peoples to the east. Genetics is only confirming what was clear from other disciplines long ago.

The complex origin of Samoyedic-speaking populations

uralic-turkic

Open access Siberian genetic diversity reveals complex origins of the Samoyedic-speaking populations, by Karafet et al. Am J Hum Biol (2018) e23194.

Interesting excerpts (emphasis mine):

Siberian groups

Consistent with their origin, Mongolic-speaking Buryats demonstrate genetic similarity with Mongols, and Turkic-speaking Altai-Kizhi and Teleuts are drawn close to CAS groups. The Tungusic-speaking Evenks collected in central and eastern Siberia cluster together and overlap with Yukagirs. Dolgans are widely scattered in the plot, justifying their recent origin from one Evenk clan, Yakuts, and Russian peasants in the 18th century (Popov, 1964). Uralic-speaking populations comprise a very wide cluster with Komi drawn to Europe, and Khants showing a closer affinity with Selkups, Tundra and Forest Nentsi. Yenisey-speaking Kets are intermingled with Selkups. Interestingly, Samoyedic-speaking Nganasans from the Taymyr Peninsula form a separate tight cluster closer to Evenks, Yukagirs, and Koryaks.

pca-siberian-uralic
Principal component analysis (PCA) using the “drop one in” technique for 27 present-day (N = 424) and 6 ancient populations (N = 20). PCA was performed on 281 093 SNPs from the intersection of our data with publicly available ancient Siberian samples

ADMIXTURE and the “Siberian component”

Among Siberians, the Komi are primarily Europeans, while Nganasans, Evenks, Yukagirs, and Koryaks are nearly 100% East Asians. At K = 4 finer scale subcontinental structure can be distinguished with the emergence of a “Siberian” component. This component is highly pronounced in the Nganasans. Outside Siberia, this component is present in Germany and in CAS at low frequency. Within ancient cultures, this component has the highest frequency in three BA Karasuk samples. It is also found in Mal’ta, ENE Afanasievo and BA Andronovo, but not in Ust’-Ishim and BA Okunevo. At K = 5, the “Siberian” component is roughly subdivided into two components with different geographic distributions. The “Nganasan” component is frequent in nearly all Siberian populations, except the Komi, Kets and Selkups. The newly derived “Selkup-Ket” component is found at high frequencies in western Siberian populations. It is observed in BA Karasuk and in Mal’ta. At K = 6, the western Siberian “Nentsi-Khant” ancestry component was developed in Forest and Tundra Nentsi, Khants. This component is also present at low levels in EUR, CAS, Tibet, and southern Siberia.

Identity-by-descent

The Dolgans share more segments with the Nganasans than within themselves (54.13 vs 41.72, Mann-Whitney test, P = .000000000001562546). The result is not surprising as the demographic data showed that the Nganasans were subjected to intense assimilation by the Dolgans in the second half of the 20th century (Goltsova, Osipova, Zhadanov, & Villems, 2005). Tundra Nentsi share more IBD with Forest Nentsi than within themselves (83.96 vs 50.3, P = .000055) possibly due to the common origin and long-term gene flow. The Ket and Selkup populations allocate significantly more IBD blocks between populations than with individuals from their own population (121.2 cM vs 85.9 cM for Kets, P = .000008, and 121.2 cM vs 114.9 cM for Selkups, P = .043).

Haplogroup N in Siberia

Although Siberia exhibits 42 haplogroups, the vast majority of Siberian Y-chromosomes belong only to 4 of the 18 major clades (N = 46.2%; C = 20.9%; Q = 14.4%; and R = 15.2%). The Y-chromosome haplogroup N is widely spread across Siberia and Eastern Europe (Ilumae et al., 2016; Karafet et al., 2002; Wong et al., 2016) and reaches its maximum frequency among Siberian populations such as Nganasans (94.1%) and Yakuts (91.9%). Within Siberia, two sister subclades N-P43 and N-L708 show different geographic distributions. N-P43 and derived haplogroups N-P63 and N- P362 (phylogenetically identical to N-B478* and N-B170, respectively) (Ilumae et al., 2016) are extremely rare in other major geographic regions. Likely originating in western Siberia, they are limited almost entirely to northwest Siberia, the Volga- Uralic regions, and the Taymyr Peninsula (ie, do not extend to eastern Siberia). Conversely, clade N-L708 is frequent in all Siberian populations except the Kets and Selkups, reaching its highest frequency in the Yakuts (91.9%).

Surprisingly, not a single sign of the proposed reindeer pastoralist horde led by Nganasans into north-eastern Europe. This is strange because “Siberian” migrants hypothetically imposed their language over Indo-Europeans quite recently, apparently after the Iron Age

Interesting comparisons among Siberian groups, though.

Minimal gene flow from western pastoralists in the Bronze Age eastern steppes

jeong-steppes-mongolia

Open access paper Bronze Age population dynamics and the rise of dairy pastoralism on the eastern Eurasian steppe, by Jeong et al. PNAS (2018).

Interesting excerpts (emphasis mine):

To understand the population history and context of dairy pastoralism in the eastern Eurasian steppe, we applied genomic and proteomic analyses to individuals buried in Late Bronze Age (LBA) burial mounds associated with the Deer Stone-Khirigsuur Complex (DSKC) in northern Mongolia. To date, DSKC sites contain the clearest and most direct evidence for animal pastoralism in the Eastern steppe before ca. 1200 BCE.

Most LBA Khövsgöls are projected on top of modern Tuvinians or Altaians, who reside in neighboring regions. In comparison with other ancient individuals, they are also close to but slightly displaced from temporally earlier Neolithic and Early Bronze Age (EBA) populations from the Shamanka II cemetry (Shamanka_EN and Shamanka_EBA, respectively) from the Lake Baikal region. However, when Native Americans are added to PC calculation, we observe that LBA Khövsgöls are displaced from modern neighbors toward Native Americans along PC2, occupying a space not overlapping with any contemporary population. Such an upward shift on PC2 is also observed in the ancient Baikal populations from the Neolithic to EBA and in the Bronze Age individuals from the Altai associated with Okunevo and Karasuk cultures.

Image modified from the article. Karasuk cluster in green, closely related to sample ARS026 in red. Principal Component Analysis (PCA) of selected 2,077 contemporary Eurasians belonging to 149 groups. Contemporary individuals are plotted using three-letter abbreviations for operational group IDs. Group IDs color coded by geographic region. Ancient Khövsgöl individuals and other selected ancient groups are represented on the plot by filled shapes. Ancient individuals are projected onto the PC space using the “lsqproject: YES” option in the smartpca program to minimize the impact of high genotype missing rate.

(…) two individuals fall on the PC space markedly separated from the others: ARS017 is placed close to ancient and modern northeast Asians, such as early Neolithic individuals from the Devil’s Gate archaeological site (22) and present-day Nivhs from the Russian far east, while ARS026 falls midway between the main cluster and western Eurasians.

Upper Paleolithic Siberians from nearby Afontova Gora and Mal’ta archaeological sites (AG3 and MA-1, respectively) (25, 26) have the highest extra affinity with the main cluster compared with other groups, including the eastern outlier ARS017, the early Neolithic Shamanka_EN, and present-day Nganasans and Tuvinians (Z > 6.7 SE for AG3). Main cluster Khövsgöl individuals mostly belong to Siberian mitochondrial (A, B, C, D, and G) and Y (all Q1a but one N1c1a) haplogroups.

(B) The top 15 populations with the most extra affinity with each of the three Khövsgöl clusters in contrast to Tuvinian (for the main cluster) or to the main cluster (for the two outliers), measured by f4(Mbuti, X; Tuvinian/Khövsgöl, Khövsgöl/ARS017/ARS026). Ancient and contemporary groups are marked by squares and circles, respectively. Darker shades represent a larger f4 statistic.

Previous studies show a close genetic relationship between WSH populations and ANE ancestry, as Yamnaya and Afanasievo are modeled as a roughly equal mixture of early Holocene Iranian/ Caucasus ancestry (IRC) and Mesolithic Eastern European hunter-gatherers, the latter of which derive a large fraction of their ancestry from ANE. It is therefore important to pinpoint the source of ANE-related ancestry in the Khövsgöl gene pool: that is, whether it derives from a pre-Bronze Age ANE population (such as the one represented by AG3) or from a Bronze Age WSH population that has both ANE and IRC ancestry.

The amount of WSH contribution remains small (e.g., 6.4 ± 1.0% from Sintashta). Assuming that the early Neolithic populations of the Khövsgöl region resembled those of the nearby Baikal region, we conclude that the Khövsgöl main cluster obtained ∼11% of their ancestry from an ANE source during the Neolithic period and a much smaller contribution of WSH ancestry (4–7%) beginning in the early Bronze Age.

khovsgol-shamanka-sintashta
Admixture modeling of Altai populations and the Khövsgöl main cluster using qpAdm. For the archaeological populations, (A) Shamanka_EBA and (B and C) Khövsgöl, each colored block represents the proportion of ancestry derived from a corresponding ancestry source in the legend. Error bars show 1 SE. (A) Shamanka_EBA is modeled as a mixture of Shamanka_EN and AG3. The Khövsgöl main cluster is modeled as (B) a two-way admixture of Shamanka_EBA+Sintashta and (C) a three-way admixture Shamanka_EN+AG3+Sintashta.

Apparently, then, the first individual with substantial WSH ancestry in the Khövsgöl population (ARS026, of haplogroup R1a-Z2123), directly dated to 1130–900 BC, is consistent with the first appearance of admixed forest-steppe-related populations like Karasuk (ca. 1200-800 BC) in the Altai. Interestingly, haplogroup N1a1a-M178 pops up (with mtDNA U5a2d1) among the earlier Khövsgöl samples.

I will repeat what I wrote recently here: Samoyedic arrived in the Altai with Karasuk and hg R1a-Z645 + Steppe_MLBA-like ancestry, admixed with Altai populations, clustering thus within an Ancient Altai cline. Only later did N1a1a subclades infiltrate Samoyedic (and Ugric) populations, bringing them closer to their modern Palaeo-Siberian cline. The shared mtDNA may support an ancestral EHG-“Siberian” cline, or else a more recent Afanasevo-related origin.

Mongolian tribes cluster with East Asians, closely related to the Japanese

New paper behind paywall Whole-genome sequencing of 175 Mongolians uncovers population-specific genetic architecture and gene flow throughout North and East Asia, by Bai et al Nature Genetics (2018).

Interesting excerpts (emphasis mine):

Genome sequencing, variant calling, and construction of the Mongolian reference panel. We collected peripheral blood with informed consent from 175 Mongolian individuals representing six distinct tribes/regions in northern China and Mongolia, including the Abaga, Khalkha, Oirat, Buryat, Sonid, and Horchin tribes.

Mongolians fill a large, less characterized gap between Admixed/Native Americans and other East Asians in the 1000G project. b, PCA of Mongolians and East Asians of 1000G. The abbreviations of EAS populations were used from reference 11.

The fixation index (FST) was used to estimate pairwise genetic differentiation among our Mongolian samples and 26 modern human populations selected from 1000G (…) the Mongolian tribes cluster with East Asian groups. The Mongolian populations show the smallest differentiation from the CHB, and FST values increase relative to the magnitude of geographical separation. The Buryat are the most differentiated tribe compared with other East Asians (1.82–2.97%), while the Horchin are the least (0.25–1.35%). All tribes are closer to the Japanese (JPT) than the CHS with the exception of the Horchin. Among the tribes, the Abaga, Khalkha, Oirat, and Sonid show the least differentiation from one another (FST < 0.15%)

A PCA places the Mongolians in close genetic proximity to a group of North Asian Siberians, including Altaians, Tuvinians, Evenki, and Yakut, indicating that the Mongolian whole-genome variation panel could be a better proxy for these groups than any populations currently in the 1000G panel

The most common Y-chromosome haplogroups are from the C3 sublineage (41.67%), including C3c (29.17%) and C3b (12.50%), followed by haplogroup O (23.61%), and haplogroup N (18.06%) (…) While haplogroups C and O are primarily restricted to Asia, haplogroup N is present at high frequency in Finns (60.5%), at low frequency in non-Mongolian East Asians (< 1%), and virtually absent throughout the remainder of European and African samples in 1000G

Comparison with Finns

Distribution of D-values from D-test under the model of [EAS, Mongolians, X, chimpanzee], where X represents the test population and chimpanzee serves as an outgroup. The positive D-value (Z > 3) indicates that the test population (X) is closer to Mongolians than to EAS. The whiskers correspond to range, and the dots to individual data points, box limits are the upper and lower quartiles. The n in each boxplot is 30. All abbreviations of populations in the figure were used from reference 11.

Of the populations included in our study, Mongolians share the second-highest level of IBD with the Finnish people (FIN), behind only Northern Han Chinese (CHB). While Mongolians share more IBD with Europeans (EUR) as a whole compared with other non-EAS people (Fig. 4b), removal of Finns from the Europeans drops the level of sharing to as low as that with South Asians (SAS) or Admixed American (AMR).

There is considerable geographic separation between modern-day Mongolians and Europe. The positive D-statistic that reveal gene flow between Mongolians and Europeans (Fig. 4c), and the high degree of IBD sharing with Finnish people in particular suggest that complex admixture may have occurred throughout northeastern Europe and Siberia. To see whether Mongolians represent the ethnic group in East Asia with the highest level of gene flow with Finnish people, we calculated a D-statistic for each set of populations [Mongolians, X, FIN, Yoruba (YRI)], where X represents a population from Siberia or Northern Canada. Most of the populations reveal an imbalance in allele frequencies that suggests gene flow with Finns (D >0, Z >3), but the greatest imbalance is observed between Siberians/Northern Canadians and Finnish, rather than between Mongolians and Finns. This pattern indicates that northern Asian populations interacted across large geographic ranges.

I guess the 1000G does not have northern Eurasian groups, because the IBD map and values would be lightening up with Palaeo-Siberian peoples

Corded Ware—Uralic (IV): Hg R1a and N in Finno-Ugric and Samoyedic expansions

haplogroup-uralians

This is the fourth of four posts on the Corded Ware—Uralic identification:

Let me begin this final post on the Corded Ware—Uralic connection with an assertion that should be obvious to everyone involved in ethnolinguistic identification of prehistoric populations but, for one reason or another, is usually forgotten. In the words of David Reich, in Who We Are and How We Got Here (2018):

Human history is full of dead ends, and we should not expect the people who lived in any one place in the past to be the direct ancestors of those who live there today.

Haplogroup N

Another recurrent argument – apart from “Siberian ancestry” – for the location of the Uralic homeland is “haplogroup N”. This is as serious as saying “haplogroup R1” to refer to Indo-European migrations, but let’s explore this possibility anyway:

Ancient haplogroups

We have now a better idea of how many ancient migrations (previously hypothesized to be associated with westward Uralic migrations) look like in genetic terms. From Damgaard et al. (Science 2018):

These serial changes in the Baikal populations are reflected in Y-chromosome lineages (Fig. SA; figs. S24 to S27, and tables S13 and SI4). MAI carries the R haplogroup, whereas the majority of Baikal_EN males belong to N lineages, which were widely distributed across Northern Eurasia (29), and the Baikal_LNBA males all carry Q haplogroups, as do most of the Okunevo_EMBA as well as some present-day Central Asians and Siberians.

The only N1c1 sample comes from Ust’Ida Late Neolithic, 180km to the north of Lake Baikal, which – together with the Bronze Age sample from the Kola peninsula, and the medieval sample from Ust’Ida – gives a good idea of the overall expansion of N subclades and Siberian ancestry among the Circum-Arctic peoples of Eurasia, speakers of Palaeo-Siberian languages.

eurasian-n-subclades
Geographical location of ancient samples belonging to major clade N of the Y-chromosome.

Modern haplogroups

What we should expect from Uralic peoples expanding with haplogroup N – seeing how Yamna expands with R1b-L23, and Corded Ware expands with R1a-Z645 – is to find a common subclade spreading with Uralic populations. Let’s see if it works like that for any N-X subclade, in data from Ilumäe et al. (2016):

haplogroup_n1
Geographic-Distribution Map of hg N3 / N1c / N1a.

Within the Eurasian circum-Arctic spread zone, N3 and N2a reveal a well-structured spread pattern where individual sub-clades show very different distributions:

N1a1-M46 (or N-TAT), formed ca. 13900 BC, TMRCA 9800 BC

   N1a1a2-B187, formed ca. 9800 BC, TMRCA 1050 AD:

The sub-clade N3b-B187 is specific to southern Siberia and Mongolia, whereas N3a-L708 is spread widely in other regions of northern Eurasia.

     N1a1a1a-L708, formed ca. 6800 BC, TMRCA 5400 BC.

The deepest clade within N3a is N3a1-B211, mostly present in the Volga-Uralic region and western Siberian Khanty and Mansi populations.

         N1a1a1a1a-L392/L1026), formed ca. 4400 BC, TMRCA 2800 BC:

           N1a1a1a1a1a-CTS2929/VL29, formed ca. 2100 BC, TMRCA 1600 BC:

In Europe, the clade N3a3-VL29 encompasses over a third of the present-day male Estonians, Latvians, and Lithuanians but is also present among Saami, Karelians, and Finns (Table S2 and Figure 3). Among the Slavic-speaking Belarusians, Ukrainians, and Russians, about three-fourths of their hg N3 Y chromosomes belong to hg N3a3.

In the post on Finno-Permic expansions, I depicted what seems to me the most likely way of infiltration of N1c-L392 lineages with Akozino warrior-traders into the western Finno-Ugric populations, with an origin around the Barents sea.

This includes the potential spread of (a minority of) N1c-B211 subclades due to contacts with Anonino on both sides of the Urals, through a northern route of forest and forest-steppe regions (equivalent to the distribution of Cherkaskul compared to Andronovo), given the spread of certain subclades in Ugric populations.

NOTE. An alternative possibility is the association of certain B211 subclades with a southern route of expansion with Pre-Scythian and Scythian populations, under whose influence the Ananino culture emerged -which would imply a very quick infiltration of certain groups of haplogroup N everywhere among Finno-Ugrics on both sides of the Urals – , and also the expansion of some subclades with Turkic-speaking peoples, who apparently expanded with alliances of different peoples. Both (Scythian and Turkic) populations expanded from East Asia, where haplogroup N (including N1c) was present since the Neolithic. I find this a worse model of expansion for upper clades, but – given the YFull estimates and the presence of this haplogroup among Turkic peoples – it is a possibility for many subclades.

           N1a1a1a1a2-Z1936, formed ca. 2800 BC, TMRCA 2400 BC:

The only notable exception from the pattern are Russians from northern regions of European Russia, where, in turn, about two-thirds of the hg N3 Y chromosomes belong to the hg N3a4-Z1936—the second west Eurasian clade. Thus, according to the frequency distribution of this clade, these Northern Russians fit better among other non-Slavic populations from northeastern Europe. N3a4 tends to increase in frequency toward the northeastern European regions but is also somewhat unexpectedly a dominant hg N3 lineage among most Turcic-speaking Volga Tatars and South-Ural Bashkirs.

Frequency-Distribution Maps of Individual Subclade N3a4 / N1a1a1a1a2-Z1936, probably with the Samic (first) and Fennic (later) expansions into Paleo-Lakelandic and Palaeo-Laplandic territories.

The expansion of N1a-Z1936 in Fennoscandia is most likely associated with the expansion of Saami into asbestos ware-related territory (like the Lovozero culture) during the Late Iron Age – and mixture with its population – , and with the later Fennic expansion to the east and north, replacing their language.

           N1a1a1a1a4-M2019 (previously N3a2), formed ca. 4400 BC, TMRCA 1700 BC:

Sub-hg N3a2-M2118 is one of the two main bifurcating branches in the nested cladistic structure of N3a2’6-M2110. It is predominantly found in populations inhabiting present-day Yakutia (Republic of Sakha) in central Siberia and at lower frequencies in the Khanty and Mansi populations, which exhibit a distinct Y-STR pattern (Table S7) potentially intrinsic to an additional clade inside the sub-hg N3a2

The second widespread sub-clade of hg N is N2a. (…):

   N1a2b-P43 (B523/FGC10846/Y3184), formed ca. 6800 BC, TMRCA ca. 2700 BC:

The absolute majority of N2a individuals belong to the second sub-clade, N2a1-B523, which diversified about 4.7 kya (95% CI = 4.0–5.5 kya). Its distribution covers the western and southern parts of Siberia, the Taimyr Peninsula, and the Volga-Uralic region with frequencies ranging from from 10% to 30% and does not extend to eastern Siberia (…)

     N1a2b2a-Y3185/FGC10847, formed ca. 2200 BC, TMRCA 800 BC:

N2a1-L1419, spread mainly in the northern part of that region.

     N1a2b2b1-B528/Y24382, formed ca. 900 BC, TMRCA ca. 900 BC:

N2a1-B528, spread in the southern Volga-Uralic region.

Haplogroup R1a

We also have a good idea of the distribution of haplogroup R1a-Z645 in ancient samples. Its subclades were associated with the Corded Ware expansion, and some of them fit quite well the early expansion of Finno-Permic, Ugric, and Samoyedic peoples to the east.

r1a-z282-z280-z2125-distribution
Modified image, from Underhill et al. (2015). Spatial frequency distributions of Z282 (green) and Z93 (blue) affiliated haplogroups.. Notice the potential Finno-Ugric-associated distribution of Z282 (especially R1a-M558, a Z280 subclade), the expansion of R1a-Z2123 subclades with Central Asian forest-steppe groups.

This is how the modern distribution of R1a among Uralians looks like, from the latest report in Tambets et al. (2018):

  • Among Fennic populations, Estonians and Karelians (ca. 1.1 million) have not suffered the greatest bottleneck of Finns (ca. 6-7 million), and show thus a greater proportion of R1a-Z280 than N1c subclades, which points to the original situation of Fennic peoples before their expansion. To trust Finnish Y-DNA to derive conclusions about the Uralic populations is as useful as relying on the Basque Y-DNA for the language spread by R1b-P312
  • Among Volga-Finnic populations, Mordovians (the closest to the original Uralic cluster, see above) show a majority of R1a lineages (27%).
  • Hungarians (ca. 13-15 million) represent the majority of Ugric (and Finno-Ugric) peoples. They are mainly R1a-Z280, also R1a-Z2123, have little N1c, and lack Siberian ancestry, and represent thus the most likely original situation of Ugric peoples in 4th century AD (read more on Avars and Hungarians).
  • Among Samoyedic peoples, the Selkup, the southernmost ones and latest to expand – that is, those not heavily admixed with Siberian populations – , also have a majority of R1a-Z2123 lineages (see also here for the original Samoyedic haplogroups to the south).

To understand the relevance of Hungarians for Ugric peoples, as well as Estonians, Karelians, and Mordovians (and northern Russians, Finno-Ugric peoples recently Russified) for Finno-Permic peoples, as opposed to the Circum-Arctic and East Siberian populations, one has to put demographics in perspective. Even a modern map can show the relevance of certain territories in the past:

Summary of ancestry + haplogroups

Fennic and Samic populations seem to be clearly influenced by Palaeo-Laplandic peoples, whereas Volga-Finnic and especially Permic populations may have received gene flow from both, but essentially Palaeo-Siberian influence from the north and east.

The fact that modern Mansis and Khantys offer the highest variation in N1a subclades, and some of the highest “Siberian ancestry” among non-Nganasans, should have raised a red flag long ago. The fact that Hungarians – supposedly stemming from a source population similar to Mansis – do not offer the same amount of N subclades or Siberian ancestry (not even close), and offer instead more R1a, in common with Estonians (among Finno-Samic peoples) and Mordvins (among Volga-Finnic peoples) should have raised a still bigger red flag. The fact that Nganasans – the model for Siberian ancestry – show completely different N1a2b-P43 lineages should have been a huge genetic red line (on top of the anthropological one) to regard them as the Uralian-type population.

We know now that ethnolinguistic groups have usually expanded with massive (usually male-biased) migrations, and that neighbouring locals often ‘resurge’ later without changing the language. That is seen in Europe after the spread of Bell Beakers, with the increase of previous ancestry and lineages in Scandinavia during the formation of the Nordic ethnolinguistic community; in Central-West Europe, with the resurgence of Neolithic ancestry (and lineages) during the Bronze Age over steppe ancestry; and in Central-East Europe (with Unetice or East European Bronze Age groups like Mierzanowice, Trzciniec, or Lusatian) showing an increase in steppe ancestry (and resurge of R1a subclades); none of them represented a radical ethnolinguistic change.

finno-ugric-haplogroup-n
Map of archaeological cultures in north-eastern Europe ca. 8th-3rd centuries BC. [The Mid-Volga Akozino group not depicted] Shaded area represents the Ananino cultural-historical society. Fading purple arrows represent likely stepped movements of subclades of haplogroup N for centuries (e.g. Siberian → Ananino → Akozino → Fennoscandia [N-VL29]; Circum-Arctic → forest-steppe [N1, N2]; etc.). Blue arrows represent eventual expansions of Uralic peoples to the north. Modified image from Vasilyev (2002).

It is not hard to model the stepped arrival, infiltration, and/or resurge of N subclades and “Siberian ancestries”, as well as their gradual expansion in certain regions, associated with certain migrations first – such as the expansions to the Circum-Arctic region, and later the Scythian- and Turkic-related movements – , as well as limited regional developments, like the known bottleneck in Finns, or the clear late expansion of Ugric and Samoyedic languages to the north among nomadic Palaeo-Siberians due to traditions of exogamy and multilingualism. This fits quite well with the different arrival of N (N1c and xN1c) lineages to the different Uralic-speaking groups, and to the stepped appearance of “Siberian ancestry” in the different regions.

The aternative

It is evident that a lot of people were too attached to the idea of Palaeolithic R1b lineages ‘native’ to western Europe speaking Basque languages; of R1a lineages speaking Indo-European and spreading with Yamna; and N lineages ‘native’ to north-eastern Europe and speaking Uralic, and this is causing widespread weeping and gnashing of teeth (instead of the joy of discovering where one’s true patrilineal ancestors come from, and what language they spoke in each given period, which is the supposed objective of genetic genealogy…)

Since an Indo-Germanic branch (as revived now by some in the Copenhaguen group to fit Kristiansen’s theory of the 1980s with recent genetic data) does not make any sense in linguistics, the finding of R1a in Yamna would not have led where some think it would have, because North-West Indo-European would still be the main Late PIE branch in Europe. Don’t take my word for it; take James P. Mallory’s (2013).

mallory-adams-tree
The levels of Indo-European reconstruction, from Mallory & Adams (2006).

If an (unlikely) Indo-Slavonic group were posited, though, such a group would still be bound (with Indo-Iranian) to the steppes with East Yamna/Poltavka (admixing with Abashevo migrants, but retaining its language), developing Sintashta/Potapovka → Srubna/Andronovo, and R1a lineages would have equally undergone the known bottlenecks of the steppes where they replaced R1b-Z2103 – which this eastern group shares with Balkan languages, a haplogroup that links therefore together the Graeco-Aryan group.

As far as I know – and there might be many other similar pet theories out there – there have been proposals of “modern Balto-Slavic-like” populations (in an obvious circular reasoning based on modern populations) in some Scythian clusters of the Iron Age.

NOTE. I will not enter into “Balto-Slavic-like R1a” of the Late Bronze Age or earlier because no one can seriously believe at this point of development of Population Genetics that autosomal similarity predating 1,500+ years the appearance of Slavs equates to their (ethnolinguistic) ancestral population, without a clear intermediate cultural and genetic trail – something we lack today in the Slavic case even for the late Roman period…

finno-saamic-palaeo-germanic-substratum
The Finnic and Saamic separation looks shallower than it actually is. Invisible convergence can be ‘triangulated’ with the help of Germanic layers of mutual loanwords (Häkkinen 2012).

We also know of R1a-Z280 lineages in Srubna, probably expanding to the west. With that in mind, and knowing that Palaeo-Germanic was in close contact with Finno-Samic while both were already separated but still in contact, and that Palaeo-Germanic was also in contact and closely related to a ‘Temematic’ distinct from Balto-Slavic (and also that early Proto-Baltic and Proto-Slavic from the Roman Iron Age and later were in contact with western Uralic) this will be the linguistic map of the Iron Age if R1a is considered to expand Indo-European from some kind of “patron-client” relationship with west Yamna:

palaeo-germanic-italo-celtic
Eastern European language map during the Late Bronze Age / Iron Age, if R1a spread Indo-European languages and Eastern Yamna spoke Indo-Slavonic. Palaeo-Germanic (i.e. Pre- to Proto-Germanic) needs to be in contact with both the Samic Lovozero population and the Fennic west Circum-Arctic one. Italic and Celtic in contact with Pre-Germanic. Germanic in contact with Temematic. Balto-Slavic in contact with Iranian, and near Fennic to allow for later loanwords. For Germanic and Temematic, see Kortlandt (2018).

You might think I have some personal or political reason against this kind of proposals. I haven’t. We have been proposing Indo-European to be the language of the European Union for more than 10 years, so to support R1b-Italo-Celtic in the whole Western Europe, R1a-Germanic in Central and Eastern Europe, and R1a-Indo-Slavonic in the steppes (as the Danish group seems to be doing) has nothing inherently bad (or good) for me. If anything, it gives more reason to support the revival of North-West Indo-European in Europe.

My problem with this proposal is that it is obviously beholden to the notion of the uninterrupted cultural, historic and ethnic continuity in certain territories. This bias is common in historiography (von Falkenhausen 1993), but it extends even more easily into the lesser known prehistory of any territory, and now more than ever some people feel the need to corrupt (pre)history based on their own haplogroups (or the majority haplogroups of their modern countries). However, more than on philosophical grounds, my rejection is based on facts: this picture is not what the combination of linguistic, archaeological, and genetic data shows. Period.

Nevertheless, if Yamna + Corded Ware represented the “big and early expansion” of Germanic and Italo-Celtic peoples proper of the dream Nazi’s Lebensraum and Fascist’s spazio vitale proposals; Uralians were Siberian hunter-gatherers that controlled the whole eastern and northern Russia, and miraculously managed to push (ethnolinguistically) Neolithic agropastoralists to the west during and after the Iron Age, with gradual (and often minimal) genetic impact; and Balto-Slavic peoples were represented by horse riders from Pokrovka/Srubna, hiding then somewhere around the forest-steppe until after the Scythian expansion, and then spreading their language (without much genetic impact) during the early Middle Ages…so be it.

This is the third of four posts on the Corded Ware—Uralic identification. See

An Eastern Uralic group?

Even though proposals of an Eastern Uralic (or Ugro-Samoyedic) group are in the minority – and those who support it tend to search for an origin of Uralic in Central Asia – , there is nothing wrong in supporting this from the point of view of a western homeland, because the eastward migration of both Proto-Ugric and Pre-Samoyedic peoples may have been coupled with each other at an early stage. It’s like Indo-Slavonic: it just doesn’t fit the linguistic data as well as the alternative, i.e. the expansion of Samoyedic first, different from a Finno-Ugric trunk. But, in case you are wondering about this possibility, here is Häkkinen’s (2012) phonological argument:

ugro-samoyedic-uralic

The case of Samoyedic is quite similar to that of Hungarian, although the earliest Palaeo-Siberian contact languages have been lost. There were contacts at least with Tocharian (Kallio 2004), Yukaghir (Rédei 1999) and Turkic (Janhunen 1998). Samoyedic also:

a) has moved far from the related languages and has been exposed to strong foreign influence

b) shares a small number of common words with other branches (from Sammallahti 1988: only 123 ‘Uralic’ words, versus 390 ‘Uralic’ + ‘Finno-Ugric’ words found in other branches than Samoyedic = 31,5 %)

c) derives phonologically from the East Uralic dialect.

The phonological level is taxonomically more reliable, since it lacks the distortion caused by invisible convergence and false divergence at the lexical level. Thus we can conclude that the traditional taxonomic model, according to which Samoyedic was the first branch to split off from the Proto-Uralic unity, is just as incorrect as the view that Hungarian was the first branch to split off.

Seima-Turbino

Late Uralic can be traced back to metallurgical cultures thanks to terms like PU *wäśka ‘copper/bronze’ (borrowed from Proto-Samoyedic *wesä into Tocharian); PU *äsa and *olna/*olni, ‘lead’ or ‘tin’, found in *äsa-wäśka ‘tin-bronze’; and e.g. *weŋći ‘knife’, borrowed into Indo-Iranian (through the stage of vocalization of nasals), appearing later as Proto-Indo-Aryan *wāćī ‘knife, awl, axe’.

It is known that the southern regions of the Abashevo culture developed Proto-Indo-Iranian-speaking Sintashta-Petrovka and Pokrovka (Early Srubna). To the north, however, Abashevo kept its Uralic nature, with continuous contacts allowing for the spread of lexicon – mainly into Finno-Ugric – , and phonetic influence – mainly Uralisms into Proto-Indo-Iranian phonology (read more here).

The northern part of Abashevo (just like the south) was mainly a metallurgical society, with Abashevo metal prospectors found also side by side with Sintashta pioneers in the Zeravshan Valley, near BMAC, in search of metal ores. About the Seima-Turbino phenomenon, from Parpola (2013):

From the Urals to the east, the chain of cultures associated with this network consisted principally of the following: the Abashevo culture (extending from the Upper Don to the Mid- and South Trans-Urals, including the important cemeteries of Sejma and Turbino), the Sintashta culture (in the southeast Urals), the Petrovka culture (in the Tobol-Ishim steppe), the Taskovo-Loginovo cultures (on the Mid- and Lower Tobol and the Mid-Irtysh), the Samus’ culture (on the Upper Ob, with the important cemetery of Rostovka), the Krotovo culture (from the forest steppe of the Mid-Irtysh to the Baraba steppe on the Upper Ob, with the important cemetery of Sopka 2), the Elunino culture (on the Upper Ob just west of the Altai mountains) and the Okunevo culture (on the Mid-Yenissei, in the Minusinsk plain, Khakassia and northern Tuva). The Okunevo culture belongs wholly to the Early Bronze Age (c. 2250–1900 BCE), but most of the other cultures apparently to its latter part, being currently dated to the pre-Andronovo horizon of c. 2100–1800 BCE (cf. Parzinger 2006: 244–312 and 336; Koryakova & Epimakhov 2007: 104–105).

The majority of the Sejma-Turbino objects are of the better quality tin-bronze, and while tin is absent in the Urals, the Altai and Sayan mountains are an important source of both copper and tin. Tin is also available in southern Central Asia. Chernykh & Kuz’minykh have accordingly suggested an eastern origin for the Sejma-Turbino network, backing this hypothesis also by the depiction on the Sejma-Turbino knives of mountain sheep and horses characteristic of that area. However, Christian Carpelan has emphasized that the local Afanas’evo and Okunevo metallurgy of the Sayan-Altai area was initially rather primitive, and could not possibly have achieved the advanced and difficult technology of casting socketed spearheads as one piece around a blank. Carpelan points out that the first spearheads of this type appear in the Middle Bronze Age Caucasia c. 2000 BCE, diffusing early on to the Mid-Volga-Kama-southern Urals area, where “it was the experienced Abashevo craftsmen who were able to take up the new techniques and develop and distribute new types of spearheads” (Carpelan & Parpola 2001: 106, cf. 99–106, 110). The animal argument is countered by reference to a dagger from Sejma on the Oka river depicting an elk’s head, with earlier north European prototypes (Carpelan & Parpola 2001: 106–109). Also the metal analysis speaks for the Abashevo origin of the Sejma-Turbino network. Out of 353 artefacts analyzed, 47% were of tin-bronze, 36% of arsenical bronze, and 8.5% of pure copper. Both the arsenical bronze and pure copper are very clearly associated with the Abashevo metallurgy.

Find spots of artefacts distributed by the Sejma-Turbino intercultural trader network, and the areas of the most important participating cultures: Abashevo, Sintashta, Petrovka. Based on Chernykh 2007: 77.

The Abashevo metal production was based on the Volga-Kama-Belaya area sandstone ores of pure copper and on the more easterly Urals deposits of arsenical copper (Figure 9). The Abashevo people, expanding from the Don and Mid-Volga to the Urals, first reached the westerly sandstone deposits of pure copper in the Volga and Kama basins, and started developing their metallurgy in this area, before moving on to the eastern side of the Urals to produce harder weapons and tools of arsenical copper. Eventually they moved even further south, to the area richest in copper in the whole Urals region, founding there the very strong and innovative Sintashta culture.

Regarding the most likely expansion of Eastern Uralic peoples:

Nataliya L’vovna Chlenova (1929–2009; cf. Korenyako & Ku’zminykh 2011) published in 1981 a detailed study of the Cherkaskul’ pottery. In her carefully prepared maps of 1981 and 1984 (Figure 10), she plotted Cherkaskul’ monuments not only in Bashkiria and the Trans-Urals, but also in thick concentrations on the Upper Irtysh, Upper Ob and Upper Yenissei, close to the Altai and Sayan mountains, precisely where the best experts suppose the homeland of Proto-Samoyed to be.

Ugric

The Cherkaskul’ culture was transformed into the genetically related Mezhovka culture (c. 1500–1000 BCE), which occupied approximately the same area from the Mid-Kama and Belaya rivers to the Tobol river in western Siberia (cf. Parzinger 2006: 444–448; Koryakova & Epimakhov 2007: 170–175). The Mezhovka culture was in close contact with the neighbouring and probably Proto-Iranian speaking Alekseevka alias Sargary culture (c. 1500–900 BCE) of northern Kazakhstan (Figure 4 no. 8) that had a Fëdorovo and Cherkaskul’ substratum and a roller pottery superstratum (cf. Parzinger 2006: 443–448; Koryakova & Epimakhov 2007: 161–170). Both the Cherkaskul’ and the Mezhovka cultures are thought to have been Proto-Ugric linguistically, on the basis of the agreement of their area with that of Mansi and Khanty speakers, who moreover in their Fëdorovo-like ornamentation have preserved evidence of continuity in material culture (cf. Chlenova 1984; Koryakova & Epimakhov 2007: 159, 175).

The Mezhovka culture was succeeded by the genetically related Gamayun culture (c. 1000–700 BCE) (cf. Parzinger 2006: 446; 542–545).

From the Gamayun culture descend Trans-Urals cultures in close contact with Finno-Permic populations of the Cis-Ural region:

  • [Proto-Mansi] Itkul’ culture (c. 700–200 BCE) distributed along the eastern slope of the Ural Mountains (cf. Parzinger 2006: 552–556). Known from its walled forts, it constituted the principal Trans-Uralian centre of metallurgy in the Iron Age, and was in contact with both the Anan’ino and Akhmylovo cultures (the metallurgical centres of the Mid-Volga and Kama-Belaya region) and the neighbouring Gorokhovo culture.
    • [Proto-Hungarian] via the Vorob’evo Group (c. 700–550 BCE) (cf. Parzinger 2006: 546–549), to the Gorokhovo culture (c. 550–400 BCE) of the Trans-Uralian forest steppe (cf. Parzinger 2006: 549–552). For various reasons the local Gorokhovo people started mobile pastoral herding and became part of the multicomponent pastoralist Sargat culture (c. 500 BCE to 300 CE), which in a broader sense comprized all cultural groups between the Tobol and Irtysh rivers, succeeding here the Sargary culture. The Sargat intercommunity was dominated by steppe nomads belonging to the Iranian-speaking Saka confederation, who in the summer migrated northwards to the forest steppe
  • [Proto-Khanty] Late Bronze Age and Early Iron Age cultures related to the Gamayunskoe and Itkul’ cultures that extended up to the Ob: the Nosilovo, Baitovo, Late Irmen’, and Krasnoozero cultures (c. 900–500 BCE). Some were in contact with the Akhmylovo on the Mid-Volga.

Samoyedic

Parpola (2012) connects the expansion of Samoyedic with the Cherkaskul variant of Andronovo. As we know, Andronovo was genetically diverse, which speaks in favour of different groups developing similar material cultures in Central Asia.

Juha Janhunen, author of the etymological dictionary of the Samoyed languages (1977), places the homeland of Proto-Samoyedic in the Minusinsk basin on the Upper Yenissei (cf. Janhunen 2009: 72). Mainly on the basis of Bulghar Turkic loanwords, Janhunen (2007: 224; 2009: 63) dates Proto-Samoyedic to the last centuries BCE. Janhunen thinks that the language of the Tagar culture (c. 800–100 BCE) ought to have been Proto-Samoyedic (cf. Janhunen 1983: 117– 118; 2009: 72; Parzinger 2001: 80 and 2006: 619–631 dates the Tagar culture c. 1000–200 BCE; Svyatko et al. 2009: 256, based on human bone samples, c. 900 BCE to 50 CE). The Tagar culture largely continues the traditions of the Karasuk culture (c. 1400–900 BCE), (…)

Genetics

Siberian ancestry

The use of a map of “Siberian ancestry” peaking in the arctic to show a supposedly late Uralic population movement (starting in the Iron Age!) seems to be the latest trend in population genomics:

siberian-ancestry-map
Frequency map of the so-called ‘Siberian’ component. From Tambets et al. (2018) (see below for ADMIXTURE in specific populations).

I guess that would make this map of Neolithic farmer ancestry represent an expansion of Indo-European from the south, because Anatolia, Greece, Italy, southern France, and Iberia – where this ancestry peaks in modern populations – are among the oldest territories where Indo-European languages were recorded:

reich-farmer-ancestry
Modern genome-wide data shows that the primary gradient of farmer ancestry in Europe does not flow southeast-to-northwest but instead in an almost perpendicular direction, a result of a major migration of pastoralists from the east that displaced much of the ancestry of the first farmers.

Probably not the right interpretation of this kind of simplistic data about modern populations, though…

The most striking thing about the “Siberian ancestry” white whale is that nobody really knows what it is; just like we did not know what “Yamnaya ancestry” was, until the most recent data is making the picture clearer. Its nature is changing with each new paper, and it can be summed up by “some ancestry we want to find that is common to Uralic-speaking peoples, and should not be CWC-related”. Tambets et al. (2018) explain quite well how they “found it”:

Overall, and specifically at lower values of K, the genetic makeup of Uralic speakers resembles that of their geographic neighbours. The Saami and (a subset of) the Mansi serve as exceptions to that pattern being more similar to geographically more distant populations (Fig. 3a, Additional file 3: S3). However, starting from K = 9, ADMIXTURE identifies a genetic component (k9, magenta in Fig. 3a, Additional file 3: S3), which is predominantly, although not exclusively, found in Uralic speakers. This component is also well visible on K = 10, which has the best cross-validation index among all tests (Additional file 3: S3B). The spatial distribution of this component (Fig. 3b) shows a frequency peak among Ob-Ugric and Samoyed speakers as well as among neighbouring Kets (Fig. 3a). The proportion of k9 decreases rapidly from West Siberia towards east, south and west, constituting on average 40% of the genetic ancestry of FU speakers in Volga-Ural region (VUR) and 20% in their Turkic-speaking neighbours (Bashkirs, Tatars, Chuvashes; Fig. 3a).

However, this ‘something’ that some people occasionally find in some Uralic populations is also common to other modern and ancient groups, and not so common in some other Uralic peoples. Simply put:

In blue, Uralic-speaking groups. “Plot of ADMIXTURE (K=3) results containing West Eurasian populations and the Nganasan. Ancient individuals from this study are represented by thicker bars.”

I already said this in the recent publication of Siberian samples, where a renamed and radiocarbon dated Finnish_IA clearly shows that Late Iron Age Saami (ca. 400 AD) had little “Siberian ancestry”, if any at all, representing the most likely Fennic (and Samic) ancestral components before their expansion into central and northern Finland, where they admixed with circum-polar peoples of asbestos ware cultures.

I will say that again and again, any time they report the so-called “Siberian ancestry” in Uralic samples, no matter how it is defined each time: it does not seem to be that special something people are looking for, but rather (at least in a great part) a quite old ancestral component forming an evident cline with EHG, whose best proximate source are Baikal_EN (and/or Devil’s Gate) at this moment, and thus also East European hunter-gatherers for Western Uralic peoples:

dzudzuana-baikal-en-admixture

In pink: samples with Baikal_EN ancestry in conservative estimates (probably marking a recent arrival of Baikal_En ancestry, see here). Modeling present-day and ancient West-Eurasians. Mixture proportions computed with qpAdm (Supplementary Information section 4). The proportion of ‘Mbuti’ ancestry represents the total of ‘Deep’ ancestry from lineages that split prior to the split of Ust’Ishim, Tianyuan, and West Eurasians and can include both ‘Basal Eurasian’ and other (e.g., Sub-Saharan African) ancestry. (Left) ‘Conservative’ estimates. Each population 367 cannot be modeled with fewer admixture events than shown. (Right) ‘Speculative’ estimates. The highest number of sources (≤5) with admixture estimates within [0,1] are shown for each population. Some of the admixture proportions are not significantly different from 0 (Supplementary Information section 4).

So either Samara_HG, Karelia_HG, and many other groups from eastern Europe all spoke Uralic according to this ADMIXTURE graphic (and the formation of steppe ancestry in the Volga-Ural region brought the Proto-Indo-European language to the steppes through the CHG/ANE expansion), or a great part of this “Siberian ancestry” found in modern Uralic-speaking populations is not what some people would like to think it is…

Modern populations

PCA clines can be looked for to represent expansions of ancient populations. Most recently, Flegontov et al. (2018) are attempting to do this with Asian populations:

For some Turkic groups in the Urals and the Altai regions and in the Volga basin, a different admixture model fits the data: the same West Eurasian source + Uralic- or Yeniseian-speaking Siberians. Thus, we have revealed an admixture cline between Scythians and the Iranian farmer genetic cluster, and two further clines connecting the former cline to distinct ancestry sources in Siberia. Interestingly, few Wusun-period individuals harbor substantial Uralic/Yeniseian-related Siberian ancestry, in contrast to preceding Scythians and later Turkic groups characterized by the Tungusic/Mongolic-related ancestry. It remains to be elucidated whether this genetic influx reflects contacts with the Xiongnu confederacy. We are currently assembling a collection of samples across the Eurasian steppe for a detailed genetic investigation of the Hunnic confederacies.

There are potential errors with this approach:

The main one is practical – does a modern cline represent an ancestral language? The answer is: sometimes. It depends on the anthropological context that we have, and especially on the precision of the PCA:

clines-himalayan

Each dot represents a sample, coded by region as indicated. The Himalayan region samples lie between the HGDP-CEPH East Asian and South Asian samples on the right-hand side of the plot. From Arciero et al. (2018).

The ‘Europe’, ‘Middle East’, etc. clines of the above PCA do not represent one language, but many. For starters, the PCA includes too many (and modern) populations, its precision is useless for ethnolinguistic groups. Which is the right level? Again, it depends.

The other error is one of detail of the clines drawn (which, in turn, depends on the precision of the PCA). For example, we can draw two paralell lines (or even one line, as in Flegontov et al. above) in one PCA graphic, but we still don’t have the direction of expansion. How do we know if this supposed “Uralic-speaking cline” goes from one region to the other? For that level of detail, we should examine closely modern Uralic-speaking peoples and Circum-Arctic populations:

uralic-cline

The real ancient Uralic cluster (drawn above in blue) is thus probably from a North-East European source (probably formed by Battle Axe / Fatyanovo-Balanovo / Abashevo) to the east into Siberian populations, and to the north into Laplandic populations (see below also on Mezhovska ancestry for the drawn ‘European cline’, which some may a priori wrongly assume to be quite late).

The fact that the three formed clines point to an admixture of CWC-related populations from North-Eastern Europe, and that variation is greater at the Palaeo-Laplandic and Palaeo-Siberian extremities compared to the CWC-related one, also supports this as the correct interpretation.

However, judging by the two main clines formed, one could be alternatively inclined to interpret that Palaeo-Laplandic and Palaeo-Siberian populations formed a huge ancestral “Uralic” ghost cluster in Siberia (spanning from the Palaeo-Laplandic to the Palaeo-Siberian one), and from there expanded Finno-Samic on one hand, and “Volga-Ugro-Samoyed” on the other. That poses different problems: an obvious linguistic and archaeological one – which I assume a lot of people do not really care about – , and a not-so-obvious genetic one (see below for ancient samples and for the expansion of haplogroup N).

To understand the simplest solution better, one can just have a look at the PCA from Bell Beaker samples in Olalde et al. (2018), which (as Reich has already explained many times) expanded directly from Yamna R1b-L23 lineages:

olalde_pca_clines
Image modified from Olalde et al. (2018). PCA of 999 Eurasian individuals. Marked is the Espersted Outlier with the approximate position of Yamna Hungary, probably the source of its admixture. Different Bell Beaker clines have been drawn, to represent approximate source of expansions from Central European sources into the different regions.

Unlike this PCA with ancient samples, where Bell Beaker clines could be a rough approximation to the real sources for each population, and where a cluster spanning all three depicted Early Bronze Age clusters could give a rough proximate source of European Bell Beakers in Hungary (and where one can even distinguish the Y-DNA bottlenecks in the L23 trunk created by each cline) the PCA of modern Uralic populations is probably not suitable for a good estimate of the ancient situation, which may be found shifted up or down of the drawn “Uralic” cluster along East European groups.

After all, we already know that the Siberian cline shows probably as much an ancient admixture event – from the original Uralic expansion to the east with Corded Ware ancestry – as another more recent one – a westward migration of Siberian ancestry (or even more than one). While we know with more or less exactitude what happened with the Palaeo-Laplandic admixture by expanding Proto-Finno-Samic populations (see here), the Proto-Ugric and Pre-Samoyedic populations formed probably more than one cline during the different ancient migrations through central Asia.

Ancient populations

Apparently, the Corded Ware expansion to the east was not marked by a huge change in ancestry. While the final version of Narasimhan et al. (2018) may show a little more detail about other forest-steppe Seima-Turbino/Andronovo-related migrations (and thus also Eastern Uralic peoples), we have already had enough information for quite some time to get a good idea.

Mezhovska‘s position is similar to the later Pre-Scythian and Scythian populations. There are some interesting details: apart from haplogroup R1a-Z280 (CTS1211+), there is one R1b-M269 (PF6494+), probably Z2103, and an outlier (out of three) in a similar position to the recently described central/southern Scythian clusters.

NOTE. The finding of R1b-M269 in the forest-steppe is probably either 1) from an Afanasevo-Okunevo origin, or 2) from an admixture with neighbouring Andronovo-related populations, such as Sargary. A third, maybe less likely option is that this haplogroup admixed with Abashevo directly (as it happened in Sintashta, Potapovka, or Pokrovka) and formed part of early Uralic migrations. In any case, since Mezhovska is a Bronze Age society from the Urals region, its association with R1b-Z2103 – like the association of R1b-Z2103 in Scythian clusters – cannot be attributed to “Thracian peoples”, a link which is (as I already said) too simplistic.

The drawn “European cline” of Hungarians (see above), leading from ‘west-like’ Mansi to Hungarian populations – and hosting also Finnic and Estonian samples – , cannot therefore be attributed simply to late “Slavic/Balkan-like” admixture.

Karasuk – located further to the east – is basically also Corded Ware peoples showing clearly a recent admixture with local ANE / Baikal_EN-like populations. In terms of haplogroups it shows haplogroup Q, R1a-Z2124, and R1a-Z2123, later found among early Hungarians, and present also in ancient Samoyedic populations now acculturated.

The most interesting aspect of both Mezhovska and Karasuk is that they seem to diverge from a point close to Ukraine_Eneolithic, which is the supposed ancestral source of Corded Ware peoples (read more about the formation of “steppe ancestry”). This means that Eastern Uralians derive from a source closer to Middle Dnieper/Abashevo populations, rather than Battle Axe (shifted to Latvian Neolithic), which is more likely the source prevalent in Finno-Permic peoples.

Their initial admixture with (Palaeo-)Siberian populations is thus seen already starting by this time in Mezhovska and especially in Karasuk, but this process (compared to modern populations) is incomplete:

A red dashed line is drawn between Yamnaya from Samara and Ami. Iron Age populations that can be modelled as mixtures of Yamnaya and East Eurasians (like the Ami) are arrayed around this line and appear to be distinct from the main North/South European cline (blue) on the left of the x axis.

We know now that Samic peoples expanded during the Late Iron Age into Palaeo-Laplandic populations, admixing with them and creating this modern cline. Finns expanded later to the north (in one of their known genetic bottlenecks), admixing with (and displacing) the Saami in Finland, especially replacing their male lines.

So how did Ugric and Samoyedic peoples admix with Palaeo-Siberian populations further, to obtain their modern cline? The answer is, logically, with East Asian migrations related to forest-steppe populations of Central Asia after the Mezhovska and Karasuk periods, i.e. during the Iron Age and later. Other groups from the forest-steppe in Central Asia show similar East Asian (“Siberian”) admixture. We know this from Narasimhan et al. (2018):

(…) we observe samples from multiple sites dated to 1700-1500 BCE (Maitan, Kairan, Oy_Dzhaylau and Zevakinsikiy) that derive up to ~25% of their ancestry from a source related to present-day East Asians and the remainder from Steppe_MLBA. A similar ancestry profile became widespread in the region by the Late Bronze Age, as documented by our time transect from Zevakinsikiy and samples from many sites dating to 1500-1000 BCE, and was ubiquitous by the Scytho-Sarmatian period in the Iron Age.

We already have some information about these later migrations:

siberian-genetic-component-chronology
Very important observation with implication of population turnover is that pre-Turkic Inner Eurasian populations’ Siberian ancestry appears predominantly “Uralic-Yeniseian” in contrast to later dominance of “Tungusic-Mongolic” sort (which does sporadically occur earlier). Alexander M. Kim

The Ugric-speaking Sargat culture in Western Siberia shows the expected mixture of haplogroups (ca. 500 BC – 500 AD), with 5 samples of hg N and 2 of hg R1a1, in Pilipenko et al. (2017). Although radiocarbon dates and subclades are lacking, N lineages probably spread late, because of the late and gradual admixture of Siberian cultures into the Sargat melting pot.

The Samoyedic-speaking Tagar culture also shows signs of a genetic turnover in Pilipenko et al. (2018):

The observed reduction in the genetic distance between the Middle Tagar population and other Scythian like populations of Southern Siberia(Fig 5; S4 Table), in our opinion, is primarily associated with an increase in the role of East Eurasian mtDNA lineages in the gene pool (up to nearly half of the gene pool) and a substantial increase in the joint frequency of haplogroups C and D (from 8.7% in the Early Tagar series to 37.5% in the Middle Tagar series). These features are characteristic of many ancient and modern populations of Southern Siberia and adjacent regions of Central Asia, including the Pazyryk population of the Altai Mountains.

Before the Iron Age, the Karasuk and Mezhovska population were probably already somehow ‘to the north’ within the ancient Steppe-Altai cline (see image below9 created by expanding Seima-Turbino- and Andronovo-related populations. During the Iron Age, further Siberian contributions with Iranian expansions must have placed Uralians of the Central Asian forest-steppe areas much closer to today’s Palaeo-Siberian cline.

However, the modern genetic picture was probably fully developed only in historic times, when Samoyedic and Ugric languages expanded to the north, only in part admixing further with Palaeo-Siberian-speaking nomads from the Circum-Arctic region (see here for a recent history of Samoyedic Enets), which justifies their more recent radical ‘northern shift’.

PC1 separates western and eastern Eurasian populations, with many inner Eurasians in the middle. PC2 separates eastern Eurasians along the north-south cline and also separates Europeans from West Asians. Ancient individuals (color-filled shapes), including two Botai individuals, are projected onto PCs calculated from present-day individuals.

This late acquisition of the language by Palaeo-Siberian nomads (without much population replacement) also justifies the wide PCA clusters of very small Siberian populations. See for example in the PCA from Tambets et al. (2018):

For their relationship with modern Mansi, we have information on Hungarian conqueror populations from Neparáczki et al. (2018):

Moreover, Y, B and N1a1a1a1a Hg-s have not been detected in Finno-Ugric populations [80–84], implying that the east Eurasian component of the Conquerors and Finno-Ugric people are probably not directly related. The same inference can be drawn from phylogenetic data, as only two Mansi samples appeared in our phylogenetic trees on the side branches (S1 Fig, Networks; 1, 4) suggesting that ancestors of the Mansis separated from Asian ancestors of the Conquerors a long time ago. This inference is also supported by genomic Admixture analysis of Siberian and Northeastern European populations [85], which revealed that Mansis received their eastern Siberian genetic component approximately 5–7 thousand years ago from ancestors of modern Even and Evenki people. Most likely the same explanation applies to the Y-chromosome N-Tat marker which originated from China [86,87] and its subclades are now widespread between various language groups of North Asia and Eastern Europe [88].

The genetic picture of Hungarians (their formed cline with Mansi and their haplogroups) may be quite useful for the true admixture found originally in Mansi peoples at the beginning of the Iron Age. By now it is clear even from modern populations that Steppe_MLBA ancestry accompanied the Uralic expansion to the east (roughly approximated in the graphic with Afanasievo_EBA + Bichon_LP EasternHG_M):

    New paper (behind paywall) A case-study in historical sociolinguistics beyond Europe: Reconstructing patterns of multilingualism in a linguistic community in Siberia, by Khanina and Meyerhoff, Journal of Historical Sociolinguistics (2018) 4(2).

    The Nganasans have been eastern neighbours of the Enets for at least several centuries, or even longer, as indicated in Figures 2 and 3.10 They often dwelled on the same grounds and had common households with the Enets. Nganasans and Enets could intermarry (Dolgikh 1962a), while the Nganasans did not marry representatives of any other ethnic groups. As a result, it was not unusual for Enets and Nganasans to live in the same tent and/or to have common relatives. Such close contact must clearly have favoured acquisition of Nganasan by Enets children and of Enets by Nganasan children from an early age.

    The Nenets have been close neighbours of all the Enets groups more recently (Figures 2 and 3). In the seventeenth century, there were only warlike contacts between the Nenets and the Enets, while in the eighteenth century the Nenets started to live on the traditional Enets lands, on the western bank of the Yenisey river, with more peaceful interactions reported. (…) Since then the same situation of intermarriages and common households has been attested for these western Enets neighbours as with the Nganasans (Dolgikh 1962a), and this has also created conditions favouring early acquisition of both languages by children.

    enets-nganasan-early
    The Enets and neighbouring peoples in the middle of the seventeenth century; map by Yuri Koryakov (http://lingvarium.org), adapted from Dolgikh (1960).

    As for the Evenkis and the Selkups, the Enets had regular contact with these peoples (Figures 2 and 3), though they were not their close neighbours: in fact, geographically, the Selkups were not neighbours at all by the end of the nineteenth century. The Evenkis had always been direct south-eastern neighbours (…) Contacts with Selkups could be trade based, or they could simply be occasional encounters on adjacent lands. (…) [With Evenkis] some sporadic contacts were similar in nature to those with the Selkups, however many other contacts were war-like. Traditionally, the Enets considered the Evenkis to have a martial spirit, and the Evenkis were known as being accustomed to stealing Enets women. A number of stories in Dolgikh (1961) concern Evenkis stealing Enets women and Enets men going to Evenki lands to find and return them. It is clear, therefore, that if Evenki or Selkup were acquired by the Enets, this happened later in life, and this acquisition required particular conditions for it, i. e. it was not readily acquired through regular or harmonious contact (as with Nganasan).

    In a pattern similar to the situation with Nganasan, in the second half of the twentieth century most Enets elders could speak Nenets (Vasil’jev 1963; Eugen Helimski p.c., the lead author’s fieldwork experience).

    enets-nganasan-late
    The Enets and neighbouring indigenous peoples: end of the nineteenth century – beginning of the twentieth century; map by Yuri Koryakov (http://lingvarium.org), adapted from
    Bruk (1961).

    At the start of the period studied, in the 1850s, the Enets linguistic community could be characterized as multilingual in the following five languages: Enets, Nganasan, Nenets, Evenki, and Russian (Figure 4). The number of Enets individuals who were able to converse in each of the other four languages differed and generally was a property of the individuals who had regular social contact with speakers of the other four languages. (…) Note that in all cases of interethnic communication there could well be a lack of perfect proficiency in a language for which the multilingualism is ascribed to the Enets community or Enets individuals: as Braunmüller and Ferraresi (2003: 3) put it: “Nobody would ever have expected to know other languages ‘perfectly’ (whatever that may mean in detail). This expectation seems to be a quite modern idea when discussing issues of bilingualism or multilingualism in general”.

    The complex interactions of Siberian populations during the 17th-19th centuries offer a reasonably good picture of the life in the centuries before these accounts, when Samoyedic peoples migrated northwards, and Palaeo-Siberian and Tungusic populations were gradually assimilated into their Uralic culture and language, through intermarriage and close contacts among naturally nomadic populations.

    You can read more about the origin of Nganasans – and other modern Samoyedic-speaking peoples – as Palaeo-Siberian populations (hence probably speaking Palaeo-Siberian languages more or less related to each other) who adopted Samoyedic languages in Wikipedia, which offers a summary of Boris Dolgikh’s On the Origin of the Nganasans (1962). Dolgikh is one of the main sources of information for these Siberian groups, as is reflected in this paper, too.

    samoyedic
    Map of distribution of Samoyedic languages (red) in the XVII century (approximate; hatching) and in the end of XX century (continuous background). Notice late expansion to north and west into the typical territory where Nomadic peoples roamed. Modified from Wikipedia, with the Tuva region labelled (see a recent genetic study on the Tuva region, one of the most likely to be originally Samoyedic-speaking).

    Why some geneticists are using Nganasans – in fact the latest Palaeo-Siberians to learn Samoyedic, already during historic times – as a model for the expansion of Uralic? I have never understood that. Among the many cases of circular reasoning based on modern populations that have been created since the start of population genomics, the use of Nganasans as a model of ‘true Uralians’ is probably the most clearly frontally opposed to what was well known in anthropology before geneticists started this new field.

    If Kallio is right, most “eastern homeland” proposals are due to the interest of Russian nationalism, which is sadly quite likely to be influencing genetic research, too. It’s like letting Hindu nationalists influence publications on steppe-related migrations. As David Reich puts it in his book:

    The tensest twenty-four hours of my scientific career came in October 2008, when my collaborator Nick Patterson and I traveled to Hyderabad to discuss these initial results with Singh and Thangaraj.

    Our meeting on October 28 was challenging. Singh and Thangaraj seemed to be threatening to nix the whole project. Prior to the meeting, we had shown them a summary of our findings, which were that Indians today descend from a mixture of two highly divergent ancestral populations, one being “West Eurasians.” Singh and Thangaraj objected to this formulation because, they argued, it implied that West Eurasian people migrated en masse into India. They correctly pointed out that our data provided no direct evidence for this conclusion. They even reasoned that there could have been a migration in the other direction, of Indians to the Near East and Europe. (…) They also implied that the suggestion of a migration from West Eurasia would be politically explosive. They did not explicitly say this, but it had obvious overtones of the idea that migration from outside India had a transformative effect on the subcontinent.

    If you add the nation-building myths in Eastern Europe (like the Russian Euro-Asian movements) to the now prevalent Indo-European—CWC idea, and a Siberian ancestry peaking in the Arctic, with little demographic or political relevance of modern Uralic-speaking peoples, you have clearly an explosive sociopolitical mix (based on a mythical Pan-Eurasian Indo-Slavonic) in the making…
