Corded Ware—Uralic (II): Finno-Permic and the expansion of N-L392/Siberian ancestry

finno-ugric-samoyedic

This is the second of three posts on the Corded Ware—Uralic identification. See Corded Ware—Uralic(I): Differences and similarities with Yamna.

I read from time to time that “we have not sampled Uralic speakers yet”, and “we are waiting to see when Uralic-speaking peoples are sampled”. Are we, though?

Proto-language homelands are based on linguistic data, such as guesstimates for dialectal evolution, loanwords and phonetic changes for language contacts, toponymy for ancient territories, etc. depending on the available information. The trace is then followed back, using available archaeological data, from the known historic speakers and territory to the appropriate potential prehistoric cultures. Only then can genetic analyses help us clarify the precise prehistoric population movements that better fit the models.

The linguistic homeland

We thought – using linguistic guesstimates and fitting prehistoric cultures and their expansion – that Yamna was the Late Proto-Indo-European culture, so when Yamna was sampled, we had Late Proto-Indo-Europeans sampled. Simple deduction.

We thought that north-eastern Europe was a Uralic-speaking area during the Neolithic:

  • For those supporting a western continuity (and assuming CWC was Indo-European), the language was present at least since the Comb Ware culture, potentially since the Mesolithic.
  • For those supporting a late introduction into Finland, Uralic expanded the latest with Abashevo-related movements after its incorporation of Volosovo and related hunter-gatherers.

The expansion to the east must have happened through progressive infiltrations with Seima-Turbino / Andronovo-related expansions.

Finding the linguistic homeland going backwards can be described today as follows:

I. Proto-Fennic homeland

Based on the number of Baltic loanwords, not attested in the more eastern Uralic branches (and reaching only partially Mordvinic), the following can be said about western Finno-Permic languages (Junttila 2014):

The Volga-Kama Basin lies still too far east to be included in a list of possible contact locations. Instead, we could look for the contact area somewhere between Estonia in the west and the surroundings of Moscow in the east, a zone with evidence of Uralic settlement in the north and Baltic on the south side.

The only linguistically well-grounded version of the Stone Age continuation theory was presented by Mikko Korhonen in 1976. Its validity, however, became heavily threatened when Koivulehto 1983a-b proved the existence of a Late Proto-Indo-European or Pre-Baltic loanword layer in Saami, Finnic, and Mordvinic. Since this layer must precede the Baltic one and it was presumably acquired in the Baltic Sea region, Koivulehto posited it on the horizon of the Battle Axe period. This forces a later dating for the Baltic–Finnic contacts.

Today the Battle Axe culture is dated at 3200 to 3000 BC, a period far too remote to correspond linguistically with Proto-Baltic (Kallio 1998a).

Since the Baltic contacts began at a very initial phase of Proto-Finnic, the language must have been relatively uniform at that time. Hence, if we consider that the layer of Baltic loanwords may have spread over the Gulf of Finland at that time, we could also insist that the whole of the Proto-Finnic language did so.

Junntila (2012).

II. Proto-Finno-Saamic homeland

The evidence of continued Palaeo-Germanic loanwords (from Pre- to Proto-Germanic stages) is certainly the most important data to locate the Finno-Saamic homeland, and from there backwards into the true Uralic homeland. Following Kallio (2017):

(…) the loanword evidence furthermore suggests that the ancestors of Finnic and Saamic had at least phonologically remained very close to Proto-Uralic as late as the Bronze Age (ca. 1700–500 BC). In particular, certain loanwords, whose Baltic and Germanic sources point to the first millennium BC, after all go back to the Finno-Saamic proto-stage, which is phonologically almost identical to the Uralic proto-stage (see especially the table in Sammallahti 1998: 198–202). This being the case, Dahl’s wave model could perhaps have some use in Uralic linguistics, too.

The presence of Pre-Germanic loanwords points rather to the centuries around the turn of the 2nd – 1st millennium BC or earlier. Proto-Germanic words must have been borrowed before the end of Germanic influence in the eastern Baltic at the beginning of the Iron Age, which sets a clear terminus ante quem ca. 800 BC.

The arrival of Bell Beaker peoples in Scandinavia ca. 2350 BC, heralding the formation of the Dagger Period, as well as the development of Pre-Germanic in common with Finnic-like populations point to the late 3rd / early 2nd millennium BC as the first time of close interaction through the Baltic region.

III. Proto-Uralic homeland

(…) the earliest Indo-European loanwords in the Uralic languages (…) show that Proto-Uralic cannot have been spoken much earlier than Proto-Indo-European dated about 3500 BC (Koivulehto 2001: 235, 257). As the same loanword evidence naturally also shows that the Uralic and Indo-European homelands were not located far from one another, the Uralic homeland can most likely be located in the Middle and Upper Volga region, right north of the Indo-European homeland*. From the beginning of the Subneolithic period about 5900 BC onwards, this region was an important innovation centre, from where several cultural waves spread to the Finnish Gulf area, such as the Sperrings Ware wave about 4900 BC, the Combed Ware wave about 3900 BC, and the Netted Ware wave about 1900 BC (Carpelan & Parpola 2001: 78–90).

The mainstream position is nowadays trying to hold together the traditional views of Corded Ware as Indo-European, and a Uralic Fennoscandia during the Bronze Age.

The following is an example of how this “Volosovo/Forest Zone hunter-gatherer theory” of Uralic origins looks like, as a ‘mixture’ of cultures and languages that benefits from the lack of genetic data for certain regions and periods (taken from Parpola 2018):

asbestos-ware
The extent of Typical Comb Ware (TCW), Asbestos- and Organic-tempered Wares (AOW) and Volosovo and Garino-Bor cultures; areas with deposits of native copper in Karelia and copperbearing sandstone in Volga-Kama-area are marked dark gray (after Zhuravlev 1977; Krajnov 1987; Nagovitsyn 1987; Chernykh 1992; Carpelan 1999; Zhul´nikov 1999). From Nordqvist et al. (2012).

The Corded Ware (or Battle Axe) culture intruded into the Eastern Baltic and coastal Finland already around 3100 BCE. The continuity hypothesis maintains that the early Proto-Finnic speakers of the coastal regions, who had come to Finland in the 4th millennium BCE with the Comb-Pitted Ware, coexisted with the Corded Ware newcomers, gradually adopting their pastoral culture and with it a number of NW-IE loanwords, but assimilating the immigrants linguistically.

The fusion of the Corded Ware and the local Comb-Pitted Ware culture resulted into the formation of the Kiukais culture (c. 2300–1500) of southwestern Finland, which around 2300 received some cultural impulses from Estonia, manifested in the appearance of the Western Textile Ceramic (which is different from the more easterly Textile Ceramic or Netted Ware, and which is first attested in Estonia c. 2700 BCE, cf. Kriiska & Tvauri 2007: 88), and supposed to have been accompanied by an influx of loanwords coming from Proto-Baltic. At the same time, the Kiukais culture is supposed to have spread the custom of burying chiefs in stone cairns to Estonia.

The coming of the Corded Ware people and their assimilation created a cultural and supposedly also a linguistic split in Finland, which the continuity hypothesis has interpreted to mean dividing Proto-Saami-Finnic unity into its two branches. Baltic Finnic, or simply Finnic, would have emerged in the coastal regions of Finland and in the northern East Baltic, while preforms of Saami would have been spoken in the inland parts of Finland.

The Nordic Bronze Age culture, correlated above with early Proto-Germanic, exerted a strong influence upon coastal Finland and Estonia 1600–700 BCE. Due to this, the Kiukais culture was transformed into the culture of Paimio ceramics (c. 1600–700 BCE), later continued by Morby ceramics (c. 700 BCE – 200 CE). The assumption is that clear cultural continuity was accompanied by linguistic continuity. Having assimilated the language of the Germanic traders and relatively few settlers of the Bronze Age, the language of coastal Finland is assumed to have reached the stage of Proto-Finnish at the beginning of the Christian era. In Estonia, the Paimio ceramics have a close counterpart in the contemporaneous Asva ceramics.

Eastern homelands?

I will not comment on Siberian or Central Asian homeland proposals, because they are obviously not mainstream, still less today when we know that Uralic was certainly in contact with Proto-Indo-European, and then with Pre- and Proto-Indo-Iranian, as supported even by the Copenhagen group in Damgaard et al. (2018).

This is what Kallio (2017) has to say about the agendas behind such proposals:

Interestingly, the only Uralicists who generally reject the Central Russian homeland are the Russian ones who prefer the Siberian homeland instead. Some Russians even advocate that the Central Russian homeland is only due to Finnish nationalism or, as one of them put it a bit more tactfully, “the political and ideological situation in Finland in the first decades of the 20th century” (Napolskikh 1995: 4).

Still, some Finns (and especially those who also belong to the “school who wants it large and wants it early”) simultaneously advocate that exactly the same Central Russian homeland is due to Finnlandisierung (Wiik 2001: 466).

Hence, for those of you willing to learn about fringe theories not related to North-Eastern Europe, you also have then the large and early version of the Uralic homeland, with Wiik’s Palaeolithic continuity of Uralic peoples spread over all of eastern and central Europe (hence EHG and R1a included):

These fringe Finnish theories look a lot like the Corded Ware expansion… Better not go the Russian or Finnish nationalist ways? Agreed then, let’s discuss only rational proposals based on current data.

The archaeological homeland

For a detailed account of the Corded Ware expansion with Battle Axe, Fatyanovo-Balanovo, and Abashevo groups into the area, you can read my recent post on the origin of R1a-Z645.

1. Textile ceramics

During the 2nd millennium BC, textile impressions appear in pottery as a feature across a wide region, from the Baltic area through the Volga to the Urals, in communities that evolve from late Corded Ware groups without much external influence.

While it has been held that this style represents a north-west expansion from the Volga region (with the “Netted Ware” expansion), there are actually at least two original textile styles, one (earlier) in the Gulf of Finland, common in the Kiukainen pottery, which evolves into the Textile ware culture proper, and another which seems to have an origin in the Middle Volga region to the south-east.

The Netted ware culture is the one that apparently expands into inner Finland – a region not densely occupied by Corded Ware groups until then. There are, however, no clear boundaries between groups of both styles; textile impressions can be easily copied without much interaction or population movement; and the oldest textile ornamentation appeared on the Gulf of Finland. Hence the tradition of naming all as groups of Textile ceramics.

textile-ware-cultures
Maximum distribution of Textile ceramics during the Bronze Age (ca. 2000-800 BC). Asbestos-tempered ware lies to the north (and is also continued in western Fennoscandia).

The fact that different adjacent groups from the Gulf of Finland and Forest Zone share similar patterns making it very difficult to differentiate between ‘Netted Ware’ or ‘Textile Ware’ groups points to:

  • close cultural connections that are maintained through the Gulf of Finland and the Forest Zone after the evolution of late Corded Ware groups; and
  • no gross population movements in the original Battle Axe / Fatyanovo regions, except for the expansion of Netted Ware to inner Finland, Karelia, and the east, where the scattered Battle Axe finds and worsening climatic conditions suggest most CWC settlements disappeared at the end of the 3rd millennium BC and recovered only later.

NOTE. This lack of population movement – or at least significant replacement by external, non-CWC groups – is confirmed in genetic investigation by continuity of CWC-related lineages (see below).

The technology present in Textile ceramics is in clear contrast to local traditions of sub-Neolithic Lovozero and Pasvik cultures of asbestos-tempered pottery to the north and east, which point to a different tradition of knowledge and learning network – showing partial continuity with previous asbestos ware, since these territories host the main sources of asbestos. We have to assume that these cultures of northern and eastern Fennoscandia represent Palaeo-European (eventually also Palaeo-Siberian) groups clearly differentiated from the south.

The Chirkovo culture (ca. 1800-700 BC) forms on the middle Volga – at roughly the same time as Netted Ware formed to the west – from the fusion of Abashevo and Balanovo elites on Volosovo territory, and is also related (like Abashevo) to materials of the Seima-Turbino phenomenon.

Bronze Age ethnolinguistic groups

In the Gulf of Finland, Kiukainen evolves into the Paimio ceramics (in Finland) — Asva Ware (in Estonia) culture, which lasts from ca. 1600 to ca. 700 BC, probably representing an evolving Finno-Saamic community, while the Netted Ware from inner Finland (the Sarsa and Tomitsa groups) and the groups from the Forest Zone possibly represent a Volga-Finnic community.

NOTE. Nevertheless, the boundaries between Textile ceramic groups are far from clear, and inner Finland Netted Ware groups seem to follow a history different from Netted Ware groups from the Middle and Upper Volga, hence they could possibly be identified as an evolving Pre-Saamic community.

Based on language contacts, with Early Baltic – Early Finnic contacts starting during the Iron Age (ca. 500 BC onwards), this is a potential picture of the situation at the end of this period, when Germanic influence on the coast starts to fade, and Lusatian culture influence is stronger:

aikio-finnic-saamic
The linguistic situation in Lapland and the northern Baltic Sea Area in the Early Iron Age prior to the expansion of Saami languages; the locations of the language groups are schematic. The black line indicates the distribution of Saami languages in the 19th century, and the gray line their approximate maximal distribution before the expansion of Finnic. Aikio (2012)

The whole Finno-Permic community remains thus in close contact, allowing for the complicated picture that Kallio mentions as potentially showing Dahl’s wave model for Uralic languages.

Genetic data shows a uniform picture of these communities, with exclusively CWC-derived ancestry and haplogroups. So in Mittnik et al. (2018) all Baltic samples show R1a-Z645 subclades, while the recent session on Estonian populations in ISBA 8 (see programme in PDF) clearly states that:

[Of the 24 Bronze Age samples from stone-cist graves] all 18 Bronze Age males belong to R1a.

Regarding non-Uralic substrates found in Saami, supposedly absorbed during the expansion to the north (and thus representing languages spoken in northern Fennoscandia during the Bronze Age) this is what Aikio (2012) has to say:

The Saami substrate in the Finnish dialects thus reveals that also Lakeland Saami languages had a large number of vocabulary items of obscure origin. Most likely many of these words were substrate in Lakeland Saami, too, and ultimately derive from languages spoken in the region before Saami. In some cases the loan origin of these words is obvious due to their secondary Proto-Saami vowel combinations such as *ā–ë in *kāvë ‘bend; small bay’ and *šāpšë ‘whitefish’. This substrate can be called ‘Palaeo-Lakelandic’, in contrast to the ‘Palaeo-Laplandic’ substrate that is prominent in the lexicon of Lapland Saami. As the Lakeland Saami languages became extinct and only fragments of their lexicon can be reconstructed via elements preserved in Finnish place-names and dialectal vocabulary, we are not in a position to actually study the features of this Palaeo-Lakelandic substrate. Its existence, however, appears evident from the material above.

If we wanted to speculate further, based on the data we have now, it is very likely that two opposing groups will be found in the region:

A) The central Finnish group, in this hypothesis the Palaeo-Lakelandic group, made up of the descendants of the Mesolithic pioneers of the Komsa and Suomusjärvi cultures, and thus mainly Baltic HG / Scandinavian HG ancestry and haplogroups I / R1b(xM269) (see more on Scandinavian HG).

siberian-ancestry-map
Frequency map of the so-called ‘Siberian’ component. From Tambets et al. (2018).

B) Lapland and Kola were probably also inhabited by similar Mesolithic populations, until it was eventually assimilated by expanding Siberian groups (of Siberian ancestry and N1c-L392 lineages) from the east – entering the region likely through the Kola peninsula – , forming the Palaeo-Laplandic group, which was in turn later replaced by expanding Proto-Saamic groups.

Siberian ancestry appears first in Fennoscandia at Bolshoy Oleni Ostrov ca. 1520 BC, with haplogroup N1c-L392 (2 samples, BOO002 and BOO004), and with Siberian ancestry. This is their likely movement in north-eastern Europe, from Lamnidis et al (2018):

The large Siberian component in the Bolshoy individuals from the Kola Peninsula provides the earliest direct genetic evidence for an eastern migration into this region. Such contact is well documented in archaeology, with the introduction of asbestos-mixed Lovozero ceramics during the second millenium BC, and the spread of even-based arrowheads in Lapland from 1,900 BCE. Additionally, the nearest counterparts of Vardøy ceramics, appearing in the area around 1,600-1,300 BCE, can be found on the Taymyr peninsula, much further to the east. Finally, the Imiyakhtakhskaya culture from Yakutia spread to the Kola Peninsula during the same period.

saamic-lovozero-pca

Obviously, these groups of asbestos-tempered ware are not connected to the Uralic expansion. From the same paper:

The fact that the Siberian genetic component is consistently shared among Uralic-speaking populations, with the exceptions of Hungarians and the non-Uralic speaking Russians, would make it tempting to equate this component with the spread of Uralic languages in the area. However, such a model may be overly simplistic. First, the presence of the Siberian component on the Kola Peninsula at ca. 4000 yBP predates most linguistic estimates of the spread of Uralic languages to the area. Second, as shown in our analyses, the admixture patterns found in historic and modern Uralic speakers are complex and in fact inconsistent with a single admixture event. Therefore, even if the Siberian genetic component partly spread alongside Uralic languages, it likely presented only an addition to populations carrying this component from earlier.

2. The Early Iron Age

The Ananino culture appears in the Vyatka-Kama area, famed for its metallurgy, with traditions similar to the North Pontic area, by this time developing Pre-Sauromatian traditions. It expanded to the north in the first half of the first millennium BC, remaining in contact with the steppes, as shown by the ‘Scythian’ nature of its material culture.

NOTE. The Ananino culture can be later followed through its zoomorphic styles into Iron Age Pjanoborskoi and Gljadenovskoi cultures, later to Ural-Siberian Middle Age cultures – Itkuska, Ust’-Poluiska, Kulaiska cultures –, which in turn can be related as prototypes of medieval Permian styles.

ananino-culture-homeland
Territory of (early and maximum) Ananino material culture. Vasilyev (2002).

At the same time as the Ananino culture begins to expand ca. 1000 BC, the Netted Ware tradition from the middle Oka expanded eastwards into the Oka-Vyatka interfluve of the middle Volga region, until then occupied by the Chirkovo culture. Eventually the Akozino or Akhmylovo group (ca. 800-300 BC) emerged from the area, showing a strong cultural influence from the Ananino culture, by that time already expanding into the Cis-Urals region.

The Akozino culture remains nevertheless linked to the western Forest Zone traditions, with long-ranging influences from as far as the Lusatian culture in Poland (in metallurgical techniques), which at this point is also closely related with cultures from Scandinavia (read more on genetics of the Tollense Valley).

Different materials from Akozino reach Fennoscandia late, at the end of the Bronze Age and beginning of the Early Iron Age, precisely when the influence of the Nordic Bronze Age culture on the Gulf of Finland was declining.

This is a period when Textile ceramic cultures in north-eastern Europe evolve into well-armed chiefdom-based groups, with each chiefdom including thousands or tens of thousands, with the main settlements being hill forts, and those in Fennoscandia starting ca. 1000-400 BC.

Mälar-type celts and Ananino-type celts appear simultaneously in Fennoscandia and the Forest Zone, with higher concentrations in south-eastern Sweden (Mälaren) and the Volga-Kama region, supporting the existence of a revived international trade network.

akozino-malar-axes-fennoscandia
Distribution of the Akozino-Mälar axes according to Sergej V. Kuz’minykh (1996: 8, Abb. 2).

The Paimio—Asva Ware culture evolves (ca. 700-200 BC) into the Morby (in Finland) — Ilmandu syle (in Estonia, Latvia, and Mälaren) culture. The old Paimio—Asva tradition continues side by side with the new one, showing a clear technical continuity with it, but with ornamentation compared to the Early Iron Age cultures of the Upper Volga area. This new south-eastern influence is seen especially in:

  • Akozino-Mälar axes (ca. 800-500 BC): introduced into the Baltic area in so great numbers – especially south-western Finland, the Åland islands, and the Mälaren area of eastern Sweden – that it is believed to be accompanied by a movement of warrior-traders of the Akozino-Akhmylovo culture, following the waterways that Vikings used more than a thousand years later. Rather than imports, they represent a copy made with local iron sources.
  • Tarand graves (ca. 500 BC – AD 400): these ‘mortuary houses’ appear in the coastal areas of northern and western Estonia and the islands, at the same time as similar graves in south-western Finland, eastern Sweden, northern Latvia and Courland. Similar burials are found in Akozino-Akhmylovo, with grave goods also from the upper and middle Volga region, while grave goods show continuity with Textile ware.

The use of asbestos increases in mainland Finnish wares with Kjelmøy Ware (ca. 700 BC – AD 300), which replaced the Lovozero Ware; and in the east in inner Finland and Karelia with the Luukonsaari and Sirnihta wares (ca. 700-500 BC – AD 200), where they replaced the previous Sarsa-Tomitsa ceramics.

The Gorodets culture appears during the Scythian period in the forest-steppe zone north and west of the Volga, shows fortified settlements, and there are documented incursions of Gorodets iron makers into the Samara valley, evidenced by deposits of their typical pottery and a bloom or iron in the region.

Iron Age ethnolinguistic groups

According to (Koryakova and Epimakhov 2007):

It is commonly accepted by archaeology, ethnography, and linguistics that the ancestors of the Permian peoples (the Udmurts, Komi-Permians, and Komi-Zyryans) left the sites of Ananyino cultural intercommunity.

NOTE. For more information on the Late Metal Ages and Early Medieval situation of Finno-Ugric languages, see e.g. South-eastern contact area of Finnic languages in the light of onomastics (Rahkonen 2013).

Certain innovations shared between Proto-Fennic (identified with the Gulf of Finland) and Proto-Mordvinic (from the Gorodets culture) point to their close contact before the Proto-Fennic expansion, and thus to the identification of Gorodets as Proto-Mordvinic, hence Akozino as Volgaic (Parpola 2018):

  • the noun paradigms and the form and function of individual cases,
  • the geminate *mm (foreign to Proto-Uralic before the development of Fennic under Germanic influence) and other non-Uralic consonant clusters.
  • the change of numeral *luka ‘ten’ with *kümmen.
  • The presence of loanwords of non-Uralic origin, related to farming and trees, potentially Palaeo-European in nature (hence possibly from Siberian influence in north-eastern Europe).

The introduction of a strongly hierarchical chiefdom system can quickly change the pre-existing social order and lead to a major genetic shift within generations, without a radical change in languages, as shown in Sintashta-Potapovka compared to the preceding Poltavka society (read more about Sintashta).

Fortified settlements in the region represented in part visiting warrior-traders settled through matrimonial relationships with local chiefs, eager to get access to coveted goods and become members of a distribution network that could guarantee them even military assistance. Such a system is also seen synchronously in other cultures of the region, like the Nordic Bronze Age and Lusatian cultures (Parpola 2013).

The most likely situation is that N1c subclades were incorporated from the Circum-Artic region during the Anonino (Permic) expansion to the north, later emerged during the formation of the Akozino group (Volgaic, under Anonino influence), and these subclades in turn infiltrated among the warrior traders that spread all over Fennoscandia and the eastern Baltic (mainly among Fennic, Saamic, Germanic, and Balto-Slavic peoples), during the age of hill forts, creating alliances partially based on exogamy strategies (Parpola 2013).

Over the course of these events, no language change is necessary in any of the cultures involved, since the centre of gravity is on the expanding culture incorporating new lineages:

  • first on the Middle Volga, when Ananino expands to the north, incorporatinig N1c lineages from the Circum-Artic region.
  • then with the expansion of the Akozino-Akhmylovo culture into Ananino territory, admixing with part of its population;
  • then on the Baltic region, when materials are imported from Akozino into Fennoscandia and the eastern Baltic (and vice versa), with local cultures being infiltrated by foreign (Akozino) warrior-traders and their materials;
  • and later with the different population movements that led eventually to a greater or lesser relevance of N1c in modern Finno-Permic populations.

To argue that this infiltration and later expansion of lineages changed the language in one culture in one of these events seems unlikely. To use this argument of “opposite movement of ethnic and language change” for different successive events, and only on selected regions and cultures (and not those where the greatest genetic and cultural impact is seen, like e.g. Sweden for Akozino materials) is illogical.

NOTE. Notice how I write here about “infiltration” and “lineages”, not “migration” or “populations”. To understand that, see below the next section on autosomal studies to compare Bronze Age, Iron Age, Medieval and Modern Estonians, and see how little the population of Estonia (homeland of Proto-Fennic and partially of Proto-Finno-Saamic) has changed since the Corded Ware migrations, suggesting genetic continuity and thus mostly close inter-regional and intra-regional contacts in the Forest Zone, hence a very limited impact of the absorbed N1c lineages (originally at some point incorporated from the Circum-Artic region). You can also check on the most recent assessment of R1a vs. N1c in modern Uralic populations.

Iron Age and later populations

From the session on Estonian samples on ISBA 8, by Tambets et al.:

[Of the 13 samples from the Iron Age tarand-graves] We found that the Iron Age individuals do in fact carry chrY hg N3 (…) Furthermore, based on their autosomal data, all of the studied individuals appear closer to hunter-gatherers and modern Estonians than Estonian CWC individuals do.

EDIT (16 OCT) A recent abstract with Saag as main author (Tambets second) cites 3 out of 5 sampled Iron Age individuals as having haplogroup N3.

estonian-pca
PCA of Estonian samples from the Bronze Age, Iron Age and Medieval times. Tambets et al. (2018, upcoming).

Looking at the plot, the genetic inflow marking the change from the Bronze Age to the Iron Age looks like an obvious expansion of nearby peoples with CWC-related ancestry, i.e. likely from the south-east, near the Middle Volga, where influence of steppe peoples is greater (hence likely Akozino) into a Proto-Fennic population already admixed (since the arrival of Corded Ware groups) with Comb Ware-like populations.

All of these groups were probably R1a-Z645 (likely R1a-Z283) since the expansion of Corded Ware peoples, with an introduction of some N1c lineages precisely during this Iron Age period. This infiltration of N1c-L392 with Akozino is obviously not directly related to Siberian cultures, given what we know about the autosomal description of Estonian samples.

Rather, N1c-L392 lineages were likely part of the incoming (Volgaic) Akozino warrior-traders, who settled among developing chiefdoms based on hill fort settlements of cultures all over the Baltic area, and began to appear thus in some of the new tarand graves associated with the Iron Age in north-eastern Europe.f

A good way to look at this is to realize that no new cluster appears compared to the data we already have from Baltic LN and BA samples from Mittnik et al. (2018), so the Estonian BA and IA clusters must be located (in a proper PCA) in the cline from Pit-Comb Ware culture through Baltic BA to Corded Ware groups:

Population labels of modern West Eurasians are given in Supplementary Fig. 7 and a zoomed-in version of the European Late Neolithic and Bronze Age samples is provided in Supplementary Fig. 8. b Ancestral components in ancient individuals estimated by ADMIXTURE (k = 11)

This genetic continuity from Corded Ware (the most likely Proto-Uralic homeland) to the Proto-Fennic and Proto-Saamic communities in the Gulf of Finland correlates very well with the known conservatism of Finno-Saamic phonology, quite similar to Finno-Ugric, and both to Proto-Uralic (Kallio 2017): The most isolated region after the expansion of Corded Ware peoples, the Gulf of Finland, shielded against migrations for almost 1,500 years, is then the most conservative – until the arrival of Akozino influence.

NOTE. This has its parallel in the phonetic conservatism of Celtic or Italic compared to Finno-Ugric-influenced Germanic, Balto-Slavic, or Indo-Iranian.

Only later would certain regions (like Finland or Lappland) suffer Y-DNA bottlenecks and further admixture events associated with population displacements and expansions, such as the spread of Fennic peoples from their Estonian homeland (evidenced by the earlier separation of South Estonian) to the north and east:

diversification-finnic
The Finnic family tree. Kallio (2014).

The initial Proto-Fennic expansion was probably coupled with the expansion of Proto-Saami to the north, with the Kjelmøy Ware absorbing the Siberian population of Lovozero Ware, and potentially in inner Finland and Karelia with the Luukonsaari and Sirnihta wares (Carpelan and Parpola 2017).

This Proto-Saami population expansion from the mainland to the north, admixing with Lovozero-related peoples, is clearly reflected in the late Iron Age Saamic samples from Levänluhta (ca. 400-800 AD), as a shift (of 2 out of 3 samples) to Siberian-like ancestry from their original CWC_Baltic-like situation (see PCA from Lamnidis et al. 2018 above).

Also, Volgaic and Permic populations from inner Finland and the Forest Zone to the Cis-Urals and Circum-Artic regions probably incorporate Siberian ancestry and N1c-L392 lineages during these and later population movements, while the westernmost populations – Estonian, Mordvinic – remain less admixed (see PCA from Tambets et al. 2018 below).

We also have data of N1c-L392 in Nordic territory in the Middle Ages, proving its likely strong presence in the Mälaren area since the Iron Age, with the arrival of Akozino warrior traders. Similarly, it is found among Balto-Slavic groups along the eastern Baltic area. Obviously, no language change is seen in Nordic Bronze Age and Lusatian territory, and none is expected in Estonian or Finnish territory, either.

Therefore, no “N1c-L392 + Siberian ancestry” can be seen expanding Finno-Ugric dialects, but rather different infiltrations and population movements with limited effects on ancestry and Y-DNA composition, depending on the specific period and region.

An issue never resolved

Because N1c-L392 subclades & Siberian ancestry, which appear in different proportions and with different origins among some modern Uralic peoples, do not appear in cultures supposed to host Uralic-speaking populations until the Iron Age, people keep looking into any direction to find the ‘true’ homeland of those ‘Uralic N1c peoples’? Kind of a full circular reasoning, anyone? The same is valid for R1a & steppe ancestry being followed for ‘Indo-Europeans’, or R1b-P312 & Neolithic farmer ancestry being traced for ‘Basques’, because of their distribution in modern populations.

I understand the caution of many pointing to the need to wait and see how samples after 2000 BC are like, in every single period, from the middle and upper Volga, Kama, southern Finland, and the Forest Zone between Fennoscandia and the steppe. It’s like waiting to see how people from Western Yamna and the Carpathian Basin after 3000 BC look like, to fill in what is lacking between East Yamna and Bell Beakers, and then between them and every single Late PIE dialect.

But the answer for Yamna-Bell Beaker-Poltavka peoples during the Late PIE expansion is always going to be “R1b-L23, but with R1a-Z645 nearby” (we already have a pretty good idea about that); and the answer for the Forest Zone and northern Cis- and Trans-Urals area – during the time when Uralic languages are known to have already been spoken there – is always going to be “R1a-Z645, but with haplogroup N nearby”, as is already clear from the data on the eastern Baltic region.

So, without a previously proposed model as to where those amateurs expressing concern about ‘not having enough data’ expect to find those ‘Uralic peoples’, all this waiting for the right data looks more like a waiting for N1c and Siberian ancestry to pop up somewhere in the historic Uralic-speaking area, to be able to say “There! A Uralic-speaking male!”. Not a very reasonable framework to deal with prehistoric peoples and their languages, I should think.

But, for those who want to do that, let me break the news to you already:

ananino-culture-balto-slavic
First N1c – Finno-Ugric person arrives in Estonia to teach Finno-Saamic to Balto-Slavic peoples.

And here it is, an appropriate fantasy description of the ethnolinguistic groups from the region. You are welcome:

  • During the Bronze Age, late Corded Ware groups evolve as the western Textile ware Fennic Balto-Slavic group in the Gulf of Finland; the Netted Ware Saamic Balto-Slavic group of inner Finland; the south Netted Ware / Akozino Volgaic Balto-Slavic groups of the Middle Volga; and the Anonino Permic Balto-Slavic group in the north-eastern Forest Zone; all developing still in close contact with each other, allowing for common traits to permeate dialects.
  • These Balto-Slavic groups would then incorporate west of the Urals during and after the Iron Age (ca. 800-500 BC first, and also later during their expansion to the north) limited ancestry and lineages from eastern European hunter-gatherer groups of Palaeo-European Fennic and Palaeo-Siberian Volgaic and Permic languages from the Circum-Artic region, but they adopted nevertheless the language of the newcomers in every single infiltration of N1c lineages and/or admixture with Siberian ancestry. Oh and don’t forget the Saamic peoples from central Sweden, of course, the famous N1c-L392 ‘Rurikid’ lineages expanding Saamic to the north and replacing Proto-Germanic…

The current model for those obsessed with modern Y-DNA is, therefore, that expanding Neolithic, Bronze Age and Iron Age cultures from north-eastern Europe adopted the languages of certain lineages originally from sub-Neolithic (Scandinavian and Siberian) hunter-gatherer populations of the Circum-Artic region; lineages that these cultures incorporated unevenly during their expansions. Hmmmm… Sounds like an inverse Western movie, where expanding Americans end up speaking Apache, and the eastern coast speaks Spanish until Italian migrants arrive and make everyone speak English… or something. A logic, no-nonsense approach to ethnolinguistic identification.

I kid you not, this is the kind of models we are going to see very soon. In 2018 and 2019, with ancient DNA able to confirm or reject archaeological hypotheses based on linguistic data, people will keep instead creating new pet theories to support preconceived ideas based on the Y-DNA prevalent among modern populations. That is, information available in the 2000s.

So what’s (so much published) ancient DNA useful for, exactly?

uralic-languages

Open access Genes reveal traces of common recent demographic history for most of the Uralic-speaking populations, by Tambets et al. Genome Biology (2018).

Interesting excerpts (emphasis mine):

Methods

A total of 286 samples of Uralic-speaking individuals, of those 121 genotyped in this study, were analysed in the context of 1514 Eurasian samples (including 14 samples published for the first time) based on whole genome single nucleotide polymorphisms (SNPs) (Additional file 1: Table S1). All these samples, together with the larger sample set of Uralic speakers, were characterized for mtDNA and chrY markers.

The question as which material cultures may have co-spread together with proto-Uralic and Uralic languages depends on the time estimates of the splits in the Uralic language tree. Deeper age estimates (6,000 BP) of the Uralic language tree suggest a connection between the spread of FU languages from the Volga River basin towards the Baltic Sea either with the expansion of the Neolithic culture of Combed Ware, e.g. [6, 7, 17, 26] or with the Neolithic Volosovo culture [7]. Younger age estimates support a link between the westward dispersion of Proto-Finno-Saamic and eastward dispersion of Proto-Samoyedic with a BA Sejma-Turbino (ST) cultural complex [14, 18, 27, 28] that mediated the diffusion of specific metal tools and weapons from the Altai Mountains over the Urals to Northern Europe or with the Netted Ware culture [23], which succeeded Volosovo culture in the west. It has been suggested that Proto-Uralic may have even served as the lingua franca of the merchants involved in the ST phenomenon [18]. All these scenarios imply that material culture of the Baltic Sea area in Europe was influenced by cultures spreading westward from the periphery of Europe and/or Siberia. Whether these dispersals involved the spread of both languages and people remains so far largely unknown.

The population structure of Uralic speakers

To contextualize the autosomal genetic diversity of Uralic speakers among other Eurasian populations (Additional file 1: Table S1), we first ran the principal component (PC) analysis (Fig. 2a, Additional file 3: Figure S1). The first two PCs (Fig. 2a, Additional file 3: Figure S1A) sketch the geography of the Eurasian populations along the East-West and North-South axes, respectively. The Uralic speakers, along with other populations speaking Slavic and Turkic languages, are scattered along the first PC axis in agreement with their geographic distribution (Figs. 1 and 2a) suggesting that geography is the main predictor of genetic affinity among the groups in the given area. Secondly, in support of this, we find that FST-distances between populations (Additional file 3: Figure S2) decay in correlation with geographical distance (Pearson’s r = 0.77, p < 0.0001). On the UPGMA tree based on these FST-distances (Fig. 2b), the Uralic speakers cluster into several different groups close to their geographic neighbours.

uralic-pca
Principal component analysis (PCA) and genetic distances of Uralic-speaking populations. a PCA (PC1 vs PC2) of the Uralic-speaking populations.

We next used ADMIXTURE [48], which presents the individuals as composed of inferred genetic components in proportions that maximize Hardy-Weinberg and linkage equilibrium in the overall sample (see the ‘Methods’ section for choice of presented K). 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). The proportion of this component among the Saami in Northern Scandinavia is again similar to that of the VUR FU speakers, which is exceptional in the geographic context. It is also notable that North Russians, sampled from near the White Sea, differ from other Russians by sporting higher proportions of k9 (10–15%), which is similar to the values we observe in their Finnic-speaking neighbours. Notably, Estonians and Hungarians, who are geographically the westernmost Uralic speakers, virtually lack the k9 cluster membership.

siberian-ancestry
Population structure of Uralic-speaking populations inferred from ADMIXTURE analysis on autosomal SNPs in Eurasian context. a Individual ancestry estimates for populations of interest for selected number of assumed ancestral populations (K3, K6, K9, K11). Ancestry components discussed in a main text (k2, k3, k5, k6, k9, k11) are indicated and have the same colours throughout. The names of the Uralic-speaking populations are indicated with blue (Finno-Ugric) or orange (Samoyedic). The full bar plot is presented in Additional file 3: Figure S3. b Frequency map of component k9

We also tested the different demographic histories of female and male lineages by comparing outgroup f3 results for autosomal and X chromosome (chrX) data for pairs of populations (Estonians, Udmurts or Khanty vs others) with high versus low probability to share their patrilineal ancestry in chrY hg N (see the ‘Methods’ section, Additional file 3: Figure S13). We found a minor but significant excess of autosomal affinity relative to chrX for pairs of populations that showed a higher than 10% chance of two randomly sampled males across the two groups sharing their chrY ancestry in hg N3-M178, compared to pairs of populations where such probability is lower than 5% (Additional file 3: Figure S13).

In sum, these results suggest that most of the Uralic speakers may indeed share some level of genetic continuity via k9, which, however, also extends to the geographically close Turkic speakers.

Identity-by-descent

We found that it is the admixture with the Siberians that makes the Western Uralic speakers different from the tested European populations (Additional file 3: Figure S4A-F, H, J, L). Differentiating between Estonians and Finns, the Siberians share more derived alleles with Finns, while the geographic neighbours of Estonians (and Finns) share more alleles with Estonians (Additional file 3: Figure S4M). Importantly, Estonians do not share more derived alleles with other Finnic, Saami, VUR FU or Ob-Ugric-speaking populations than Latvians (Additional file 3: Figure S4O). The difference between Estonians and Latvians is instead manifested through significantly higher levels of shared drift between Estonians and Siberians on the one hand and Latvians and their immediate geographic neighbours on the other hand. None of the Uralic speakers, including linguistically close Khanty and Mansi, show significantly closer affinities to the Hungarians than any non-FU population from NE Europe (Additional file 3: Figure S4R).

ibd-uralic-genetics
Share of ~ 1–2 cM identity-by-descent (IBD) segments within and between regional groups of Uralic speakers. For each Uralic-speaking population representing lines in this matrix, we performed permutation test to estimate if it shows higher IBD segment sharing with other population (listed in columns) as compared to their geographic control group. Empty rectangles indicate no excess IBD sharing, rectangles filled in blue indicate comparisons when statistically significant excess IBD sharing was detected between one Uralic-speaking population with another Uralic-speaking population (listed in columns), rectangles filled in green mark the comparisons when a Uralic-speaking population shows excess IBD sharing with a non-Uralic-speaking population. For each tested Uralic speaker (matrix rows) populations in the control group that were used to generate permuted samples are indicated using small circles. For example, the rectangle filled in blue for Vepsians and Komis (A) implies that the Uralic-speaking Vepsians share more IBD segments with the Uralic-speaking Komis than the geographic control group for Vepsians, i.e. populations indicated with small circles (Central and North Russians, Swedes, Latvians and Lithuanians). The rectangle filled in green for Vepsians and Dolgans shows that the Uralic-speaking Vepsians share more IBD segments with the non-Uralic-speaking Dolgans than the geographic control group

Time of Siberian admixture

The time depth of the Globetrotter (Fig. 5b) inferred admixture events is relatively recent—500–1900 AD (see also complementary ALDER results, in Additional file 13: Table S12 and Additional file 3: Figure S7)—and agrees broadly with the results reported in Busby et al. [55]. A more detailed examination of the ALDER dates, however, reveals an interesting pattern. The admixture events detected in the Baltic Sea region and VUR Uralic speakers are the oldest (800–900 AD or older) followed by those in VUR Turkic speakers (∼1200–1300 AD), while the admixture dates for most of the Siberian populations (>1500 AD) are the most recent (Additional file 3: Figure S7). The West Eurasian influx into West Siberia seen in modern genomes was thus very recent, while the East Eurasian influx into NE Europe seems to have taken place within the first millennium AD (Fig. 5b, Additional file 3: Figure S7).

Affinities of the Uralic speakers with ancient Eurasians

We next calculated outgroup f3-statistics [48] to estimate the extent of shared genetic drift between modern and ancient Eurasians (Additional file 14: Table S13, Additional file 3: Figures S8-S9). Consistent with previous reports [45, 50], we find that the NE European populations including the Uralic speakers share more drift with any European Mesolithic hunter-gatherer group than Central or Western Europeans (Additional file 3: Figure S9A-C). Contrasting the genetic contribution of western hunter-gatherers (WHG) and eastern hunter-gatherers (EHG), we find that VUR Uralic speakers and the Saami share more drift with EHG. Conversely, WHG shares more drift with the Finnic and West European populations (Additional file 3: Figure S9A). Interestingly, we see a similar pattern of excess of shared drift between VUR and EHG if we substitute WHG with the aDNA sample from the Yamnaya culture (Additional file 3: Figure S9D). As reported before [2, 45], the genetic contribution of European early farmers decreases along an axis from Southern Europe towards the Ural Mountains (Fig. 6, Additional file 3: Figure S9E-F).

Colour codes for the terminal nodes: pink—modern populations (‘Population X’ refers to test population) and yellow—ancient populations (aDNA samples and their pools). Nodes coloured other than pink or yellow are hypothetical intermediate populations. We putatively named nodes which we used as admixture sources using the main recipient among known populations. The colours of intermediate nodes on the qpGraph model match those on the admixture proportions panel. b Admixture proportions (%) of ancestral components. We calculated the admixture proportions summing up the relative shares of a set of intermediate populations to explain the full spectrum of admixture components in the test population. We further did the same for the intermediate node CWC’ and present the proportions of the mixing three components in the stacked column bar of CWC’. Colour codes for ancestral components are as follows: dark green—Western hunter gatherer (WHG’); light green—Eastern hunter gatherer (EHG’); grey—European early farmer (LBK’); dark blue—carriers of Corded Ware culture (CWC’); and dark grey—Siberian. CWC’ consists of three sub-components: blue—Caucasian hunter-gatherer in Yamnaya (CHGinY’); light blue—Eastern hunter-gatherer in Yamnaya (EHGinY’); and light grey—Neolithic Levant (NeolL’)

We then used the qpGraph software [48] to test alternative demographic scenarios by trying to fit the genetic diversity observed in a range of the extant Finno-Ugric populations through a model involving the four basic European ancestral components: WHG, EHG, early farmers (LBK), steppe people of Yamnaya/Corded Ware culture (CWC) and a Siberian component (Fig. 6, Additional file 3: Figure S10). We chose the modern Nganasans to serve as a proxy for the latter component because we see least evidence for Western Eurasian admixture (Additional file 3: Figure S3) among them. We also tested the Khantys for that proxy but the model did not fit (yielding f2-statistics, Z-score > 3). The only Uralic-speaking population that did not fit into the tested model with five ancestral components were Hungarians. The qpGraph estimates of the contributions from the Siberian component show that it is the main ancestry component in the West Siberian Uralic speakers and constitutes up to one third of the genomes of modern VUR and the Saami (Fig. 6). It drops, however, to less than 10% in most of NE Europe, to 5% in Estonians and close to zero in Latvians and Lithuanians.

Discussion

uralic-groups-haplogroup-r1a
Additional file 6: Table S5. Y chromosome haplogroup frequencies in Eurasia. Modified by me: in bold haplogroup N1c and R1a from Uralic-speaking populations, with those in red showing where R1a is the major haplogroup. Observe that all Uralic subgroups – Finno-Permic, Ugric, and Samoyedic – have some populations with a majority of R1a lineages.

One of the notable observations that stands out in the fineSTRUCTURE analysis is that neither Hungarians nor Estonians or Mordovians form genetic clusters with other Uralic speakers but instead do so with a broad spectrum of geographically adjacent samples. Despite the documented history of the migration of Magyars [63] and their linguistic affinity to Khantys and Mansis, who today live east of the Ural Mountains, there is nothing in the present-day gene pool of the sampled Hungarians that we could tie specifically to other Uralic speakers.

Perhaps even more surprisingly, we found that Estonians, who show close affinities in IBD analysis to neighbouring Finnic speakers and Saami, do not share an excess of IBD segments with the VUR or Siberian Uralic speakers. This is eIn this context, it is important to remind that the limited (5%, Fig. 6) East Eurasian impact in the autosomal gene pool of modern Estonians contrasts with the fact that more than 30% of Estonian (but not Hungarian) men carry chrY N3 that has an East Eurasian origin and is very frequent among NE European Uralic speakers [36]. However, the spread of chrY hg N3 is not language group specific as it shows similar frequencies in Baltic-speaking Latvians and Lithuanians, and in North Russians, who in all our analyses are very similar to Finnic-speakers. The latter, however, are believed to have either significantly admixed with their Uralic-speaking neighbours or have undergone a language shift from Uralic to Indo-European [38].ven more striking considering that the immediate neighbours—Finns, Vepsians and Karelians—do.

With some exceptions such as Estonians, Hungarians and Mordovians, both IBD sharing and Globetrotter results suggest that there are detectable inter-regional haplotype sharing ties between Uralic speakers from West Siberia and VUR, and between NE European Uralic speakers and VUR. In other words, there is a fragmented pattern of haplotype sharing between populations but no unifying signal of sharing that unite all the studied Uralic speakers.

Comments

The paper is obviously trying to find a “N1c/Siberian ancestry = Uralic” link, but it shows (as previous papers using ancient DNA) that this identification is impossible, because it is not possible to identify “N1c=Siberian ancestry”, “N1c=Uralic”, or “Siberian ancestry = Uralic”. In fact, the arrival of N subclades and Siberian ancestry are late, both events (probably multiple stepped events) are unrelated to each other, and represent east-west demic diffusion waves (as well as founder effects) that probably coincide in part with the Scythian and Turkic (or associated) expansions, i.e. too late for any model of Proto-Uralic or Proto-Finno-Ugric expansion.

On the other hand, it shows interesting data regarding ancestry of populations that show increased Siberian influence, such as those easternmost groups admixed with Yeniseian-like populations (Samoyedic), those showing strong founder effects (Finnic), or those isolated in the Circum-Artic region with neighbouring Siberian peoples in Kola (Saami). All in all, Hungarians, Estonians and Mordovians seem to show the original situation better than the other groups, which is also reflected in part in Y-DNA, conserved as a majority of R1a lineages precisely in these groups. Just another reminder that CWC-related ancestry is found in every single Uralic group, and that it represents the main ancestral component in all non-Samoyedic groups.

The qpGraph shows the ancestor of Yamna (likely Khvalynsk) and Corded Ware stemming as different populations from a common (likely Neolithic) node – whose difference is based on the proportion of Anatolian-related ancestry – , that is, probably before the Indo-Hittite expansion; and ends with CWC groups forming the base for all Uralic peoples. Below is a detail of the qpGraph on the left, and my old guess (2017) on the right, for comparison:

#EDIT (22 sep 2018): I enjoyed re-reading it, and found this particular paragraph funny:

Despite the documented history of the migration of Magyars [63] and their linguistic affinity to Khantys and Mansis, who today live east of the Ural Mountains, there is nothing in the present-day gene pool of the sampled Hungarians that we could tie specifically to other Uralic speakers.

They are so obsessed with finding a link to Siberian ancestry and N1c, and so convinced of Kristiansen’s idea of CWC=Indo-European, that they forgot to examine their own data from a critical point of view, and see the clear link between all Uralic peoples with Corded Ware ancestry and R1a-Z645 subclades… Here is a reminder about Hungarians and R1a-Z282, and about the expansion of R1a-Z645 with Uralic peoples.

Mitogenomes from Avar nomadic elite show Inner Asian origin

ring-pommel-swords

Inner Asian maternal genetic origin of the Avar period nomadic elite in the 7th century AD Carpathian Basin, by Csáky et al. bioRxiv (2018).

Abstract (emphasis mine):

After 568 AD the nomadic Avars settled in the Carpathian Basin and founded their empire, which was an important force in Central Europe until the beginning of the 9th century AD. The Avar elite was probably of Inner Asian origin; its identification with the Rourans (who ruled the region of today’s Mongolia and North China in the 4th-6th centuries AD) is widely accepted in the historical research.

Here, we study the whole mitochondrial genomes of twenty-three 7th century and two 8th century AD individuals from a well-characterised Avar elite group of burials excavated in Hungary. Most of them were buried with high value prestige artefacts and their skulls showed Mongoloid morphological traits.

The majority (64%) of the studied samples’ mitochondrial DNA variability belongs to Asian haplogroups (C, D, F, M, R, Y and Z). This Avar elite group shows affinities to several ancient and modern Inner Asian populations.

The genetic results verify the historical thesis on the Inner Asian origin of the Avar elite, as not only a military retinue consisting of armed men, but an endogamous group of families migrated. This correlates well with records on historical nomadic societies where maternal lineages were as important as paternal descent.

The MDS plot shows the connection of the Avars (AVAR) to the Central-Asian populations of the Late Iron Age (C-ASIA_LIAge) and Medieval period (C-ASIA_Medieval) along coordinate 1 and coordinate 2, which is caused by non-significant genetic distances between these populations. The European ancient populations are situated on the left part of the plot, where the Iberian (IB_EBRAge), Central-European (C-EU_BRAge) and British (BRIT_BRAge) populations from Early Bronze Age and Bronze Age are clustered along coordinate 2, while the Neolithic populations from Germany (GER_Neo), Hungary (HUN_Neo), Near-East (TUR_ _Neo) and Baltic region (BALT_Neo) are located on the skirt of the plot along coordinate 1. The linearised Slatkin FST values, abbreviations and references are presented in Table S4.

Interesting excerpts:

The mitochondrial genome sequences can be assigned to a wide range of the Eurasian haplogroups with dominance of the Asian lineages, which represent 64% of the variability: four samples belong to Asian macrohaplogroup C (two C4a1a4, one C4a1a4a and one C4b6); five samples to macrohaplogroup D (one by one D4i2, D4j, D4j12, D4j5a, D5b1), and three individuals to F (two F1b1b and one F1b1f). Each haplogroup M7c1b2b, R2, Y1a1 and Z1a1 is represented by one individual. One further haplogroup, M7 (probably M7c1b2b), was detected (sample AC20); however, the poor quality of its sequence data (2.19x average coverage) did not allow further analysis of this sample.

European lineages (occurring mainly among females) are represented by the following haplogroups: H (one H5a2 and one H8a1), one J1b1a1, three T1a (two T1a1 and one T1a1b), one U5a1 and one U5b1b (Table S1).

We detected two identical F1b1f haplotypes (AC11 female and AC12 male) and two identical C4a1a4 haplotypes (AC13 and AC15 males) from the same cemetery of Kunszállás; these matches indicate the maternal kinship of these individuals. There is no chronological difference between the female and the male from Grave 30 and 32 (AC11 and AC12), but the two males buried in Grave 28 and 52 (AC13 and AC15) are not contemporaries; they lived at least 2-3 generations apart.

ward-clustering-ancient-populations
Ward type clustering of 44 ancient populations. The Ward type clustering shows separation of Asian and European populations. The Avar elite group (AVAR) is situated on an Asian branch and clustered together with Central Asian populations from Late Iron Age (C-ASIA_LIAge) and Medieval period (C-ASIA_Medieval), furthermore with Xiongnu period population from Mongolia (MON_Xiongnu) and Scythians from the Altai region (E-EU_IAge_Scyth). P values are given in percent as red numbers on the dendogram, where red rectangles indicate clusters with significant p values. The abbreviations and references are presented in Table S2.

The Avar period elite shows the lowest and non-significant genetic distances to ancient Central Asian populations dated to the Late Iron Age (Hunnic) and to the Medieval period, which is displayed on the ancient MDS plot (Fig. 4); these connections are also reflected on the haplogroup based Ward-type clustering tree (Fig. 3). Building of these large Central Asian sample pools is enabled by the small number of samples per cultural/ethnic group. Further mitogenomic data from Inner Asia are needed to specify the ancient genetic connections; however, genomic analyses are also set back by the state of archaeological research, i.e. the lack of human remains from the 4th-5th century Mongolia, which would be a particularly important region in the study of the Avar elite’s origin.

The investigated elite group from the Avar period elite also shows low genetic distances and phylogenetic connections to several Central and Inner Asian modern populations. Our results indicate that the source population of the elite group of the Avar Qaganate might have existed in Inner Asia (region of today’s Mongolia and North China) and the studied stratum of the Avars moved from there westwards towards Europe. Further genetic connections of the Avars to modern populations living to East and North of Inner Asia (Yakuts, Buryats, Tungus) probably indicate common source populations.

MDS with the 44 modern populations and the Avar elite group. The Multidimensional Scaling plot is displayed based on linearised Slatkin FST values calculated based on whole mitochondrial sequences (stress value is 0.0677). The MDS plot shows differentiation of European, Near-Eastern, Central- and East-Asian populations along coordinates 1 and 2. The Avar elite (AVAR) is located on the Asian part of plot and clustered with Uyghurs from Northwest-China (NW-CHIN_UYG) and Han Chinese (CHIN), as well as with Burusho and Hazara populations from the Central-Asian Highland (Pakistan). The linearised Slatkin FST values, abbreviations and references are presented in Table S5.

Sadly, no Y-DNA is available from this paper, although haplogroups Q, C2, or R1b (xM269) are probably to be expected, given the reported mtDNA. A replacement of the male population with subsequent migrations is obvious from the current distribution of Y-DNA haplogroups in the Carpathian Basin.

Hungarians and Corded Ware

Ancient Hungarians are important to understand the evolution, not only of Ugric, but also of Finno-Ugric peoples and their origin, since they show a genetic picture before more recent population expansions, genetic drift, and bottlenecks in eastern Europe.

By now it is evident that the migration of Magyar clans from their homeland in the Cis-Urals region (from the 4th century AD on) happened after the first waves of late and gradual expansion of N1c subclades among Finno-Ugric peoples, but before the bottlenecks seen in modern populations of eastern Europe.

In Ob-Ugric peoples, from the scarce data found in Pimenoff et al. (2018), we can see how Siberian N subclades expanded further after the separation of Magyars, evidenced by the inverted proportion of haplogroups R1a and N in modern Khantys and Mansis compared to Hungarians, and the diversity of N subclades compared to modern Fennic peoples.

Similarly to Hungarians, the situation of modern Estonians (where R1a and N subclades show approximately the same proportion, ca. 33%) is probably closer to Fennic peoples in Antiquity, not having undergone the latest strong founder effect evident in modern Finns after their expansion to the north.

Modern Hungary

This is data from recent papers, summed up in Wikipedia:

  • In Semino et al. (2001) they found among 45 Palóc from Budapest and northern Hungary: 60% R1a, 13% R1b, 11% I, 9% E, 2% G, 2% J2.
  • In Csányi et al. (2008) Among 100 Hungarian men, 90 of whom from the Great Hungarian Plain: 30% R1a, 15% R1b, 13% I2a1, 13% J2, 9% E1b1b1a, 8% I1, 3% G2, 3% J1, 3% I*, 1% E*, 1% F*, 1% K*. Among 97 Székelys, in Romania: 20% R1b, 19% R1a, 17% I1, 11% J2, 10% J1, 8% E1b1b1a, 5% I2a1, 5% G2, 3% P*, 1% E*, 1% N.
  • In Pamjav et al. (2011), among 230 samples expected to include 6-8% Gypsy peoples: 26% R1a, 20% I2a, 19% R1b, 7% I, 6% J2, 5% H, 5% G2a, 5% E1b1b1a1, 3% J1, <1% N, <1% R2.
  • In Pamjav et al. (2017), from the Bodrogköz population: R1a-M458 (20.4%), I2a1-P37 (19%), R1b-M343 (15%), R1a-Z280 (14.3%), E1b-M78 (10.2%), and N1c-Tat (6.2%).

NOTE. The N1c-Tat found in Bodrogköz belongs to the N1c-VL29 subgroup, more frequent among Balto-Slavic peoples, which may suggest (yet again) an initial stage of the expansion of N subclades among Finno-Ugric peoples by the time of the Hungarian migration.

This is the data from FTDNA group on Hungary (copied from a Wikipedia summary of 2017 data):

  • 26.1% R1a (15% Z280, 6.5% M458, 0.9% Z93=>S23201, 3.7% unknown)
  • 19.2% R1b (6% L11-P312/U106, 5.3% P312, 4.2% L23/Z2103, 3.7% U106)
  • 16.9% I2 (15.2% CTS10228, 1.4% M223, 0.5% L38)
  • 8.3% I1
  • 8.1% J2 (5.3% M410, 2.8% M102)
  • 6.9% E1b1b1 (6% V13, 0.3% V22, 0.3% M123, 0.3% M81)
  • 6.9% G2a
  • 3.2% N (1.4% Z9136, 0.5% M2019/VL67, 0.5% Y7310, 0.9% Z16981)- note: only unrelated males are sampled
  • 2.3% Q (1.2% YP789, 0.9% M346, 0.2% M242)
  • 0.9% T
  • 0.5% J1
  • 0.2% L
  • 0.2% C

R1a-Z280 stands out in FDNA (which we have to assume has no geographic preference among modern Hungarians), while R1a-M458 is prevalent in the north, which probably points to its relationship with (at least West) Slavic populations.

Ancient Hungarians

We already knew that Hungarians show similarities with Srubna and Hunnic peoples, and this paper shows a good reason for the similarities with the Huns.

Also, recent population movements in the region (before the Avars) probably increased the proportion of R1b-L23 and I1 subclades (related to Roman and Germanic peoples) as well as possibly R1a-Z283 (mainly M458, related to the expansion of Slavs). From Understanding 6th-century barbarian social organization and migration through paleogenomics, by Amorim et al. (2018):

NOTE. The sample SZ15, of haplogroup R1a1a1b1a3a (S200), belongs to the Germanic branch Z284, which has a completely different history with its integration into the Nordic Bronze Age community.

Interesting is the Szólád Bronze Age sample of R1a1a1b2a2a (Z2123) subclade (ca. 2100-1700 BC), which is possibly the same haplogroup found in King Béla III [Z93+ (80.6%), Z2123+ (10.8%)]*. Nevertheless, Z2123 refers to an upper clade, found also in East Andronovo sites in Narasimhan et al. (2018), as well as in the modern population of the Tarim Basin.

NOTE. For more on the analysis of probability of the actual subclade, see here.

Bronze Age R1a-Z93 samples of central-east Europe – like the Balkans BA sample (ca. 1750-1625 BC) from Merichleri, of R1a1a1b2 subclade – correspond most likely to the expansion of Iranian-speaking peoples in the early 2nd millennium BC, probably to the westward expansion of the Srubna culture.

The specific subclade of King Béla III, on the other hand, probably corresponds to the more recent expansion of Magyar tribes settled in the region during the 9th century AD, so the specific subclade must have separated from those found in central-east Europe and in Andronovo during the Corded Ware expansion.

Notice the potential Finno-Ugric-associated distribution of Z282 (including M558, a Z280 subclade) according to ancient maps; the northern Eurasian finds of Z2125 (upper clade of Z2123); and the potential of M458 subclades representing a west-east expansion of Balto-Slavic as a western outgroup of an original Fenno-Ugric population, equivalent to Z284 in Scandinavia.

The study by Csányi et al. (2008), where the Tat C allele was found in 2 of 4 ancient samples, showed thus a potential 50:50 relationship of N1c in ancient Magyars, which is striking given the modern 1-3% a mere 1,000 years later, without any relevant population movement in between. This result remains to be reproduced with the current technology.

In fact, recent studies of ancient Magyars, from the 10th to the 12th century, have not shown any N1c sample, and have confirmed instead the ancient presence of R1a (two other samples, interred near Béla III), R1b (four samples), I2a (two samples) J1, and E1b, a mixed genetic picture which is more in line with what is expected.

So the question that I recently posed about east Corded Ware groups remains open: were Proto-Ugric peoples mainly of R1a-Z282 or R1a-Z93 subclades? Without ancient DNA from Middle Dnieper, Fatyanovo, Afanasevo, and the succeeding cultures (like Netted Ware) in north-eastern Europe, it is difficult to say.

It is very likely that they are going to show mainly a mixture of both R1a-Z282 and R1a-Z93 lineages, with later populations showing a higher proportion of R1a-Z280 subclades. Whether this mixture happened already during the Corded Ware period, or is the result of later developments, is still unknown. What is certain is that Hungarian N1a1a1a-L708 subclades belong to more recent additions of Siberian haplogroups to the Ugric stock, probably during the Iron Age, just centuries before the Magyar expansion.
