Waves of Palaeolithic ANE ancestry driven by P subclades; new CWC-like Finnish Iron Age

New preprint The population history of northeastern Siberia since the Pleistocene, by Sikora et al. bioRxiv (2018).

Interesting excerpts (emphasis mine; most internal references removed):

ANE ancestry

The earliest, most secure archaeological evidence of human occupation of the region comes from the artefact-rich, high-latitude (~70° N) Yana RHS site dated to ~31.6 kya (…)

The Yana RHS human remains represent the earliest direct evidence of human presence in northeastern Siberia, a population we refer to as “Ancient North Siberians” (ANS). Both Yana RHS individuals were unrelated males, and belong to mitochondrial haplogroup U, predominant among ancient West Eurasian hunter-gatherers, and to Y chromosome haplogroup P1, ancestral to haplogroups Q and R, which are widespread among present-day Eurasians and Native Americans.

Symmetry tests using f4 statistics reject tree-like clade relationships with both Early West Eurasians (EWE; Sunghir) and Early East Asians (EEA; Tianyuan); however, Yana is genetically closer to EWE, despite its geographic location in northeastern Siberia

Using admixture graphs (qpGraph) and outgroup-based estimation of mixture proportions (qpAdm), we find that Yana can be modelled as EWE with ~25% contribution from EEA

Among all ancient individuals, Yana shares the most genetic drift with Mal’ta, and f4 statistics show that Mal’ta shares more alleles with Yana than with EWE (e.g. f4(Mbuti,Mal’ta;Sunghir,Yana) = 0.0019, Z = 3.99). Mal’ta and Yana also exhibit a similar pattern of genetic affinities to both EWE and EEA, consistent with previous studies.The ANE lineage can thus be considered a descendant of the ANS lineage, demonstrating that by 31.6 kya early representatives of this lineage were widespread across northern Eurasia, including far northeastern Siberia.

Ancient Palaeosiberian

(…) the 9.8 kya Kolyma1 individual, representing a group we term “Ancient Paleosiberians” (AP). Our results indicate that AP are derived from a first major genetic shift observed in the region. Principal component analysis (PCA), outgroup f3-statistics and mtDNA and Y chromosome haplogroups (G1b and Q1a1a, respectively) demonstrate a close affinity between AP and present-day Koryaks, Itelmen and Chukchis, as well as with Native Americans.

For both AP and Native Americans, ANS ancestry appears more closely related to Mal’ta than Yana, therefore rejecting a direct contribution of Yana to later AP or Native American groups.

Lake Baikal Neolithic – Bronze Age

(…) the newly reported genomes from Ust’Belaya and recently published neighbouring Neolithic and Bronze Age sites show a succession of three distinct genetic ancestries over a ~6 ky time span. The earliest individuals show predominantly East Asian ancestry, closely related to the ancient individuals from DGC. In the early Bronze Age (BA), we observe a resurgence of AP ancestry (up to ~50% ancestry fraction), as well as influence of West Eurasian Steppe ANE ancestry represented by the early BA individuals from Afanasievo in the Altai region (~10%) This is consistent with previous reports of gene flow from an unknown ANE-related source into Lake Baikal hunter-gatherers.

Our results suggest a southward expansion of AP as a possible source, which is also consistent with the replacement of Y chromosome lineages observed at Lake Baikal, from predominantly haplogroup N in the Neolithic to haplogroup Q in the BA. Finally, the most recent individual from Ust’Belaya, dated to ~600 years ago, falls along the Neosiberian cline, similar to the ~760 year-old ‘Young Yana’ individual from northeastern Siberia, demonstrating the widespread distribution of Neosiberian ancestry in the most recent epoch.

Finland Saami

At the western edge of northern Eurasia, genetic and strontium isotope data from ancient individuals at the Levänluhta site documents the presence of Saami ancestry in Southern Finland in the Late Holocene 1.5 kya. This ancestry component is currently limited to the northern fringes of the region, mirroring the pattern observed for AP ancestry in northeastern Siberia. However, while the ancient Saami individuals harbour East Asian ancestry, we find that this is better modelled by DGC rather than AP, suggesting that AP influence was likely restricted to the eastern side of the Urals. Comparison of ancient Finns and Saami with their present-day counterparts reveals additional gene flow over the past 1.6 kya, with evidence for West Eurasian admixture into modern Saami. The ancient Finn from Levänluhta shows lower Siberian ancestry than modern Finns .

Finnish_IA (ca. 350 AD) is probably a Saami-speaking individual, just like the newly reported Saami_IA from Levänluhta ca. 400-600 AD (since Fennic peoples were then likely around the Gulf of Finland).

NOTE. The conflicting strontium isotope data on certain samples from the supplementary material hint at possible external origin of some of the previously reported (and possibly the newly reported) Saami Iron Age individuals, possibly hundreds of km. to the southeast of Levänluhta (coast of the Bothnian Sea), which could imply the start of a Finnic push to the north. It is unclear which samples they are referring to, and it is also unclear which interpretation of the archaeological data is more likely, though.

These new samples give us some more information than what we already had, because Finnish_IA implies that there was few East Asian admixture (if any at all) in west Finland during the Roman Iron Age, which pushes still farther forward in time the expected appearance of Siberian ancestry among Saamic (first) and Fennic populations (later). It is unclear whether this East Asian ancestry found in Finnish_IA is actually related to DGC, or it is rather related to the ENA-like ancestry found already in Baltic hunter-gatherers (i.e. in some EHG samples from Karelia), for which Baikal_EN is a good proxy in Lazaridis et al. (2018).

Since Bronze Age and Iron Age samples from Estonia show more Baltic_HG drift compared to Corded Ware samples, it is likely that this supposedly DGC-related ancestry (here considered part of the ‘Siberian ancestry’) is actually an EHG-related ENA component of north-east European hunter-gatherers, with whom Finno-Saamic peoples admixed during the expansion of the Corded Ware culture into Finland.

The paper finds thus increased (probably the actual) Siberian ancestry in modern Finns compared to this Iron Age Saami individual. Coupled with the new Saami Iron Age samples (and the previously reported three) from between one to three centuries later – showing the start of Siberian ancestry influx – , we can begin to establish when the expansion of Siberian ancestry happened in central Finland, and thus quite likely when the Saami began to expand to the north and east and admix with Palaeo-Laplandic peoples.

One sample of haplogroup N1a1a1a1a4a1-M1982, Yana_MED, is found in the Arctic region (north-eastern Yakutia) ca. 1100 AD. Since it is derived from N1a1a1a1a-L392, it might be a surprise for some to find it in a clearly non-Uralic speaking environment at the same time other subclades of this haplogroup were admixing in the west with well-established Finno-Saamic, Volga-Finnic, Ugric, and Samoyedic populations…

On the growing doubts that these data – contradicting the CWC=IE theory – are creating among geneticists (from the supplementary materials):

NOTE. This paper comes from the Copenhagen group, also signed by Kristiansen, one of today’s strongest supporters of this connection

The Proto-Saami language evolved in southern Finland and Karelia in the Early Iron Age, an area now host to Finnish and the closely related Karelian, but with Saami toponyms showing that the latter two languages are intrusive here (Saarikivi 2004). Saami-speaking populations are thought to have retreated to Lapland during the Middle Iron Age (300–800 AD), where it diverged into the modern Saami dialects. Genetically, the northward retreat of the Saami language correlates with the documented decrease of Saami ancestry in Southern Finland between the Iron Age and the modern period (cf. Lamnidis et al. 2018).

On the way to Lapland, the Saami replaced at least two linguistically obscure groups. This can be inferred from 1) an influx of non-Uralic loanwords into Proto-Saami in the Finnish Lakeland area, and 2) an influx of non-Uralic, non-Germanic words into Saami dialects in Lapland (Aikio 2012). Both of these borrowing events imply contact with non-Saami-speaking groups, e.g. non-Uralic-speaking hunter-gatherers that may have left a genetic and linguistic footprint on modern Saami populations.

The linguistic prehistory of Finland thus does not allow for a straightforward interpretation of the genetic data. The detection of East Asian ancestry in the genetically Saami individual is indicative of a population movement from the east (cf. Lamnidis et al. 2018, Rootsi et al. 2007), one that given the affinities with the ~7.6 ky old individuals from the Devil’s Gate Cave may have been a western extension of the Neosiberian turnover. However, it remains unclear whether this gene flow should be associated with the arrival of Uralic speakers, thus providing further support for a Uralic homeland in Eastern Eurasia, or with an earlier immigration of pre-Uralic, so-called “Paleo-Lakelandic” groups.

I think the genetic interpretation is already straightforward, though. Just another sneak peek at how this late admixture with non-Uralians (mainly Palaeo-Lakelandic and Palaeo-Laplandic peoples from Lovozero and related asbestos ware cultures) is going to unfold among expanding Saami-speaking populations after this newly published Finnish_IA sample, i.e. during the late Iron Age, thanks to Lamnidis et al. (2018):

Also, still no trace of R1a in far East Asia (reported as M17 ca. 5300 BC near Lake Baikal by Moussa et al. 2016), so I still have doubts about my previous assessment that R1a split into M17 (and thus also M417) in Siberia, with those expanding hunter-gatherer pottery.

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.

uralic-time-space
Some datings for the traditional proto-stages from Uralic to Finnic. Kallio (2014).

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):

Palaeolithic boat peoples and Finno-Ugric. Source

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 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.

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).

malar-celts-ananino

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:

baltic-samples
PCA and ADMIXTURE analysis reflecting three time periods in Northern European prehistory. a Principal components analysis of 1012 present-day West Eurasians (grey points, modern Baltic populations in dark grey) with 294 projected published ancient and 38 ancient North European samples introduced in this study (marked with a red outline). 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.

estonians-hungarians-mordvinian
Selection of the PCA, with the group of Estonians, Mordovians, and Hungarians selected. See Tambets et al. (2018) for more information.

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?

Global demographic history inferred from mitogenomes

Open access Global demographic history of human populations inferred from whole mitochondrial genomes, by Miller, Manica, and Amos, Royal Society Open Science (2018).

Relevant excerpts (emphasis mine):

Material

The Phase 3 sequence data from 20 populations, comprising five populations for each of the four main geographical regions of Europe, East Asia, South Asia and Africa, were downloaded from the 1000 Genomes Project website (www.1000genomes.org/data, [8]), including whole mitochondrial genome data for 1999 individuals. We decided not to analyse populations from the Americas due to the region’s complex history of admixture [13,14].

The European populations were as follows: Finnish sampled in Finland (FIN); European Caucasians resident in Utah, USA (CEU); British in England and Scotland (GBR); an Iberian population from Spain (IBS) and Toscani from Italy (TSI). Representing East Asia were the Han Chinese in Beijing (CHB); Southern Han Chinese (CHS); Dai Chinese from Xishuangbanna, China (CDX); Kinh population from Ho Chi Minh City, Vietnam (KHV) and Japanese from Tokyo (JPT). The South Asian populations were Punjabi Indians from Lahore, Pakistan (PJL); Gujarati Indians in Houston, USA (GIH) as well as Indian Telugu sampled in the UK (ITU); Bengali from Bangladesh (BEB) and Sri Lankan Tamil from the UK (STU). (…)

Method

We analysed our mtDNA data with the extended Bayesian skyline plot (EBSP) method, a Bayesian, non-parametric technique for inferring past population size fluctuations from genetic data. Building on the previous Bayesian skyline plot (BSP) approach, EBSP uses a piecewise-linear model and Markov chain Monte Carlo (MCMC) methods to reconstruct a populations’ demographic history [17] and is implemented in the software package BEAST v. 2.3.2 [11]. Alignments for each of the 20 populations were loaded separately into the Bayesian Evolutionary Analysis Utility tool (BEAUti v. 2.3.2) in NEXUS format.

Comparisons between regions, circles, are colour-coded: black ¼ AFR-EA; yellow ¼ AFR-EUR; blue ¼ AFR-SA; orange ¼ EUR-EA; green ¼ EA-SA; red ¼ EUR-SA. Comparisons within regions, squares, are coded: peach ¼ EUR; pink ¼ EA; dark blue ¼ EA; light blue ¼ AFR. Profile similarity is calculated as inferred size difference summed over 20 evenly spaced intervals (see Material and methods).

Regional demographic histories

Europe:

The five European profiles are presented in figure 2. The four southerly populations all show profiles with a stable size up to approximately 14 ka followed by a sudden, rapid increase that becomes progressively less steep towards the present. There is also a north-south trend, with confidence intervals becoming broader towards the north, particularly for the oldest time-points. The Finnish population profile appears rather different, but this is to be expected both because it is so far north and because previous studies have identified Finns as a strong genetic outlier in Europe [19–22].

South Asia:

The five profiles for South Asia are shown in figure 3. All populations reveal a period of rapid growth approximately 45–40 ka which then slows. Near the present the two southerly populations, GIH and STU both show evidence of a decline. However, this may be due to these samples being drawn from populations no longer living on the subcontinent, with the downward trend capturing a bottleneck associated with moving to Europe/America, perhaps accentuated by the tendency for immigrant populations to group by region, religion and race [23].

Another hint at the role of Corded Ware peoples in spreading Uralic languages into north-eastern Europe, found in mtDNA analysis of the Finnish population

corded-ware-migration-yamna

Open article at Scientific Reports (Nature): Identification and analysis of mtDNA genomes attributed to Finns reveal long-stagnant demographic trends obscured in the total diversity, by Översti et al. (2017).

Of special interest is its depiction of Finland’s past as including the expansion of Corded Ware population of mtDNA U5b1b2 (and probably Y-DNA R1a-M417 subclades), most likely Uralic speakers of the Forest Zone, to the north of the Yamna culture (where Late Proto-Indo-European was spoken).

A later expansion of other subclades – particularly Y-DNA N1c -, was probably associated with the later western expansion of the Eurasian Seima-Turbino phenomenon, and its current prevalence in Finnish Y-DNA haplogroups might have been the consequence of the population decline ca. 1500 BC, and later Iron Age population bottleneck (with the population peak ca. 500 AD) described in the article.

That would more naturally explain the ‘cultural diffusion’ of Finnic languages into invading eastern N1c lineages, a diffusion which would have been in fact a long-term, quite gradual replacement of previously prevalent Y-DNA R1a subclades in the region, as supported by the prevalent “steppe” component in genome-wide ancestry of Finns.

Therefore, there were probably no sudden, strong population (and thus cultural) changes associated with the arrival of N1c lineages, like the ones seen with R1a (Corded Ware / Uralic) and R1b (Yamna / Proto-Indo-European) expansions in Europe.

How the Saami fit into this scheme is not yet obvious, though.

Abstract:

In Europe, modern mitochondrial diversity is relatively homogeneous and suggests an ubiquitous rapid population growth since the Neolithic revolution. Similar patterns also have been observed in mitochondrial control region data in Finland, which contrasts with the distinctive autosomal and Y-chromosomal diversity among Finns. A different picture emerges from the 843 whole mitochondrial genomes from modern Finns analyzed here. Up to one third of the subhaplogroups can be considered as Finn-characteristic, i.e. rather common in Finland but virtually absent or rare elsewhere in Europe. Bayesian phylogenetic analyses suggest that most of these attributed Finnish lineages date back to around 3,000–5,000 years, coinciding with the arrival of Corded Ware culture and agriculture into Finland. Bayesian estimation of past effective population sizes reveals two differing demographic histories: 1) the ‘local’ Finnish mtDNA haplotypes yielding small and dwindling size estimates for most of the past; and 2) the ‘immigrant’ haplotypes showing growth typical of most European populations. The results based on the local diversity are more in line with that known about Finns from other studies, e.g., Y-chromosome analyses and archaeology findings. The mitochondrial gene pool thus may contain signals of local population history that cannot be readily deduced from the total diversity.

From its results:

In general, there appears to be two loose and largely overlapping clusters among the Finn-characteristic haplogroups: the first between 1,000–2,000 ybp and the second around 3,300–5,500 ybp. The age of the older cluster coincides temporally with the arrival of the Corded-Ware culture and, notably, the spread of agriculture in Finland. The arrival and spread of agriculture, temporally corresponding with the age estimates for most of the haplogroups characteristic of Finns, might be a sign of population size increase enabled by the new mode of subsistence, resulting in reduced drift and accumulation of genetic diversity in the population.

(…)

Another insight in the past population sizes in Finland is based on radiocarbon-dated archaeological findings in different time periods. These analyses suggest two prehistoric population peaks in Finland, the Stone Age peak (c. 5,500 ybp) and the Metal Age peak (~1,500 ybp). Both of these peaks were followed by a population decline, which appears to have reached its ebb around 3,500 ybp. These developments are not distinguishable in the BSPs. However, these ages correspond well to the two haplogroup age clusters described above. The presumably less severe Iron Age population bottleneck seen in the archaeological data, 1,500–1,300 ybp, temporally coincides with the population size reduction visible for the Finn-characteristic subhaplogroups.

Rhetoric of debates, discussions and arguments: Useful destructive criticism for scientific & academic research, reasons and personal opinions; the example of Proto-Indo-European language revival

Rhetoric (Wikipedia) is the art of harnessing reason, emotions and authority, through language, with a view to persuade an audience and, by persuading, to convince this audience to act, to pass judgement or to identify with given values. The word derives from PIE root wer-, ‘speak’, as in MIE zero-grade wrdhom, ‘word’, or full-grade werdhom, ‘verb’; from wrētōr ρήτωρ (rhētōr), “orator” [built like e.g. wistōr (<*widtor), Gk. ἵστωρ (histōr), “a wise man, one who knows right, a judge” (from which ‘history’), from PIE root weid-, ‘see, know’]; from that noun is adj. wrētorikós, Gk. ρητορικός (rhētorikós), “oratorical, skilled in speaking”, and fem. wrētorikā, GK ρητορική (rhētorikē). According to Plato, rhetoric is the “art of enchanting the soul”.

When related to Proto-Indo-European language revival, as well as in modern scientific research of any discipline, discussions are sometimes interesting in light of historical rhetoric, as they might get really close to some classical (counter-)argumentative resources, however unknown they are to their users…

Sophists taught that every argument could be countered with an opposing argument, that an argument’s effectiveness derived from how “likely” it appeared to the audience (its probability of seeming true), and that any probability argument could be countered with an inverted probability argument. Thus, if it seemed likely that a strong, poor man were guilty of robbing a rich, weak man, the strong poor man could argue, on the contrary, that this very likelihood (that he would be a suspect) makes it unlikely that he committed the crime, since he would most likely be apprehended for the crime. They also taught and were known for their ability to make the weaker (or worse) argument the stronger (or better).

So, for example, if people might generally think that evolution is very likely to have occured, because of the scientifical data available, one only has to say something like “God put those proofs there to confound people and prove their faith“. And, even if there is no single reason to give why that person is entitled to interpret the Bible that way, and to determine what ‘God thought’ when ‘inventing proofs of a false evolution’, in fact there is no need to give rational arguments: this very likelihood of evolution is in itself a proof of how good God is in cheating us…

Statistics was a discipline mostly unknown to sophists, but I’m sure they more or less imagined the typical bell curve that population beliefs and opinions follow. If interpreted the other way round, one could say that the more an idea is believed by people, the more likely is that someone will come along with another, competing one. In fact, that’s natural evolution, too: without that universal trend that life has to differentiate itself from the normal, matter would have never changed and get more and more complicated…

That trend is observed in research, too, as man is obviously another animal and its intelligence another natural feature subjected to the evolutive machinery of nature. That’s why Occam’s razor is never a sufficient argument to end a research field or hypothesis: you have e.g. Gimbutas’ theories (or Renfrew’s, if you like) – even though obviously not completely proven hypothesis -, about some prehistoric speakers being successful in their conquests and migrations through Eurasia, which infers with logic that what happend with Indo-European languages expansion is what has almost always happened in the known history of language expansion, using the most probable extrapolation they can with the facts we know. But you will still find competing hypothesis about an unlikely millennium-long, peaceful spread and mix of languages through and from Europe or Asia, based on some controversial facts and a great part of imagination. And, even if such theories are far away from what can generally be considered rational, they will certainly find supporters; and it’s not bad that such unlikely ideas emerge: science is built up thanks to some of such marginal ideas which eventually prove true; apart from the million ones that prove false and disappear, and some dozens that are sadly able to remain, like homeopathy or Esperanto-like conlanging, as I’ve said before. The same happens with the human body, which went through mutation obtaining lots of advantages, but at the same time dragging some genetic illnesses along…

About Proto-Indo-European research, it’s more or less straightforward which hypothesis and theories are considered generally accepted, and which ones minority views. Nevertheless, that doesn’t prevent renown experts from accepting some marginal hypothesis in some aspects of PIE reconstruction, while keeping the general view on other ones; neither does that prevent renown linguists and philologists to consider Proto-Indo-European, or comparative and historical grammar in general, an absurd work: the ex-Dean of a southern Spanish University, a Latin professor, deems PIE an “invention”; in his words, “from Lat. pater, Gk. pater, and Eng. father, we say there is a language that said what, ‘pater‘? pfff”; he obviously considers “language=written & renown language system”; the problem with that thought is that if PIE becomes spoken (i.e. written too) and renown, just as Old Latin became Classical Latin – instead of disappearing as the other Italic dialects – the whole reasoning is useless; so it’s also useless now. One of the most famous Indo-Europeanists in Spain, F. Adrados (e.g. marginal supporter of Etruscan as an IE language) and Bernabé (e.g. marginal supporter of the Glottalic theory, I think), even if dedicated to Indo-European reconstruction, deemed PIE revival – in some news in Spanish newspaper El Mundo – a “uthopia“, but considered at the same time possible that Greek and Latin (respectively) became EU’s official language: it’s not that they don’t consider speaking PIE impossible, but only that there are “better” alternatives: better, I guess, for Romance or Greek speakers or philologists…

About Proto-Indo-European language revival for Europe, thus, it is difficult to ascertain if it is the most rational choice, as it is to ascertain if liberal thoughts are more rational than conservative ones. I have lived in other countries within the European Union, and have visited other parts of Spain where the spoken language is not Spanish; from that experience, the different attitudes I’ve found are overwhelming: when you speak in English or German anywhere in Europe, the conversation is everything but fluent; also, if you speak English in the UK, German in Germany, French in France, or Czech in Czechia, even mastering quite well the regional language, you’ll never get the same reaction as if a Catalan (from a Catalan-speaking region) speaks Spanish in, say, Galicia (a Galician-Portuguese speaking region), as both use a language (Spanish) common to both of them. That was also the idea behind the first Esperanto out there, probably Volapük, and it has been the idea behind every conlang trying to be THE International Auxiliary Language since then; and none has succeeded. That was also the idea behind Hebrew revival in Israel, for speakers of a hundred different languages living in the same territory: they had other modern, common languages to choose instead of an ancient, partially incomplete, and “difficult” (in Esperantist terms) one, too, and it succeeded.

Latin use in Europe, on the other hand, has been declining ever since the first Romance dialects developed, and had its latest offcial (i.e. legal) use in Europe, apart from the Catholic church, at the beginning of the XX century in Hungary – curiously enough, a non-Indo-European speaking country. Its revival has been proposed a thousand times since then, but has never recovered its prestige, as Germanic-speaking countries have taken the lead in Western Europe, and Slavic-speaking countries in the East. It is hard to explain now why English- or German- or Polish-speaking peoples should learn and speak again the language of the Romans and the Roman Empire, with which they have little history in common…

The rest of known language revivals, like Cornish or Manx, or even e.g. the partial revival (“sociolect”) of Katharevousa Greek, not to talk about the so-called “revivals” – in fact “language revitalizations” – of Basque, Catalan, Breton, Ukrainian, etc. have been just regionally oriented language (or prestige + vocabulary) revivals with cultural or social purposes.

So, is Proto-Indo-European revival a “correct”, or “sufficiently rational” option, given the known facts? As an opinion, it is neither correct nor incorrect, as being “Indo-Europeanist for Europe” is like being leftist or conservative in politics; just like supporting Hebrew revival wasn’t (a hundred years ago) “sufficiently rational” in itself, and controversy over its revival have never ended. But, the reasons behind PIE revival can and should be questioned, as the reasons behind a conlang adoption (i.e. the concepts of “better” and “easier” when applied to language) can and should be critically reviewed. In Proto-Indo-European, it refers – I think – to two main questions:

1) Did Proto-Indo-European exist? i.e. can we confidently consider any proto-language something different from especulation or mere unproven hypothesis? The answer is “it depends”. Proto-Indo-European was probably a language spoken by prehistorical people, as probable as any generally accepted scientific theory we can support without experimental proofs, like theories on the Universe, its creation or development: they might prove wrong in the future, but – following the necessary abstraction and common sense – it’s not difficult to accept most individual premises and facts surrounding them. That migh be said about proto-languages like Proto-Slavic (ca. 1 AD), Proto-Germanic (ca. 1000 BC), Proto-Greek or Proto-Indo-Iranian (ca. 2000 BC) or Proto-Indo-European, especially about its European or North-Western subbranch (ca. 2500-2000 BC); on the other hand, however, about proto-languages like ‘Proto-Eurasiatic’ or ‘Proto-Nostratic’, or ‘Proto-Indo-Tyrrhenian’, or ‘Proto-Thraco-Illyrian’, or ‘Proto-Indo-Uralic’, or ‘Proto-Italo-Celtic’ (or even Proto-Italic), or ‘Proto-Balto-Slavic’, and the hundred other proposed combinations, it is impossible to prove beyond doubt if and when they were languages at all.

2) Is the Proto-Indo-European reconstruction trustable enough to be “revived”? i.e. can we consider it a speakable language, or just a linguistic theoretical approach? Again, it depends, but here mostly mixed with political opinions. In light of Ancient Hebrew – a language that ceased to be spoken 2500 years ago -, “revived” as a modern language introducing thousands of newly coined terms – many of them from Indo-European origin -, to the point that some want to name it “Israeli”, instead of “Hebrew” (as we call MIE “European” or “Europaio” instead of “Indo-European”), I guess the answer is clearly yes, it’s possible: in any possible case, Indo-European languages have a continuated history of more than 4000 years, and modern terms need only (in most cases) a sound-law adjustment to be translated into PIE. Also, in light of the other proto-languages with a high scientifical basis and a similar time span, like Proto-Uralic, Proto-Semitic or Proto-Dravidian, there is no possible comparison with Proto-Indo-European: while PIE is practically a fully reconstructed and well-known language without written texts to ‘confirm’ our knowledge, the rest are just experimental (mainly vocabulary-based) reconstructions. There are, thus, proto-languages and proto-languages, as there are well-known natural dead languages and poorly attested ones; PIE is therefore one of the few ones which might be called today a real, natural language, like Proto-Germanic, Proto-Slavic or Proto-Indo-Aryan.

However, anti-Europeanists (or, better, anti-Indo-Europeanists for the European Union) won’t find it difficult to say a simple “a proto-language is not enough to be revived, as Ancient Hebrew was written down and PIE wasn’t”, thus disguising their sceptic views on the politics behind the project with seemingly rational discussion. While others will also state, in light of our clear confrontation with conlangs, that “proto-language is nothing different from a conlang”, thus disguising their real interest in spreading their personal desire that a proto-language be similar to a conlang. One only has to say: “Classical Latin couldn’t be reconstructed by comparing Spanish, French and Italian” – when, in fact, the question should be something like “could the common, Late Vulgar Latin, be reconstructed with a high degree of confidence, having just the writings of the first mediaeval romance languages?” The answer is probably a simple “yes,and quite well”, until proven the contrary, but by expressing the first doubt one can easily transform the possible-reconstruction argument in an apparently unlikely one; enough to convince those who want to be convinced…

Thus, whereas some people consider PIE a natural language, confidently reconstructed, but impossible to speak today because of political matters, others just consider it another invention, nothing different from Esperanto, while Esperantist talk about it as a “worse” or “more difficult” alternative to it: you could nevertheless find all opinions mixed together when it comes to destructive discussions, as the objective is not to defend an own rational and worked idea, but simply to destroy the appearance (or likelihood, in sophistic terms) of the rival’s idea. Be it anti-Europeanism, anti-Indo-European-reconstrution or anti-everything-else-than-Esperanto, you don’t have to defend your position: just repeat your known anti- cliches, and you’ve “won”. Apparently, at least.

Cicero noted what Greek rhetors already knew before about usual debates, and how arguments should be made and countered so that no idea is left accepted. In that sense, discussions were (and are) generally so unnecessary, that the Socratic Method seems to be still the best philosophical approach to discussions, even those concerning scientifical (i.e. “most probable”) facts: Instead of arriving at answers, non-expert (and often expert) discussion is used to break down the theories others hold, not “to go beyond the axioms and postulates we take for granted” and obtain a better knowledge, as Greek philosophers put it, but just to destroy what others build up.

So, for example, we might get these general rules to counter any argument, even if it’s not only based on opinions, but also on generally accepted facts:

1) Demonstrate the falseness of a part of the rival’s argument; then, infer the falseness of the whole reasoning. For example, let’s say Gimbutas’ view is out-dated, or that we at Dnghu included something considered nowadays ‘wrong’ in our grammar: then PIE revival is also mistaken; nothing more to explain. Or, let’s say that Hebrew revival is not “equal” to a proto-language revival, and that therefore the comparison is ‘false’ – even if comparisons are there to compare similar cases, not “equal” cases, which would be absurd – then, the whole PIE revival project is ‘equivocal’ or ‘absurd’. That’s the view about PIE revival you can find in some comments made on American blogs out there.

2) You can also confirm a part of your rival’s argument, and then, by doing it, carry that argument to its extreme, to the extent that the consequences of it are intolerable, and the paroxism completely distorts your rival’s argument. That’s more or less what I usually do when confronting conlanging as a real option for the European Union, by saying “OK, let’s adopt the ‘better’ and ‘easier’ language: first Esperanto, then the “better” and “easier” Esperanzo, then Lojban, then Pilosofio, then Mazematio, etc. etc. ad infinitum” – so, as a conclusion, one might accept that “better” and “easier” are not actually good reasons to adopt a language; hence the arguments based on “better” and “easier” cliches are opinion, not ratio.

3) The most common now (and then, I guess, in spoken language) is personal discredit, by which you can infer that his argument is also corrupted. That is what some have made when lacking more arguments, calling me personally (and the Indo-European language Association in general ?!) a “racist”, “nazi”, or “KKK-like” group; or trying to discredit me personally by saying I don’t master the English language; or that I misspelled or ‘was wrong’ in reconstructing this or that PIE name or noun; or even just because I am “an amateur”, – thus suggesting we all have to be “language professionals” to propose a trustable PIE revival. A recent example of this is our latest Esperantist visitor, saying I am “close to being racist” because I propose PIE for the EU – thus obviously inviting readers to identify “language=race”, saying that “I propose one language = I propose one race = I am a racist”, and therefore if “I=racist” and “I propose PIE revival” => “PIE=x”. The whole reasoning is nonsense, but he is not the first – and won’t be the last – educated individual to say (and possibly believe) that…

4) The fourth is actually only a minor method derived from the third, used in desperate cases, which consists on taking a sensible, emotional example of the consequences of the generalization of the rival’s argument, to demonstrate the moral baseness of the one who defends it; then, if he is discredited, his argument is corrupted, too [see point 3]… That is what some desperate people do when saying that PIE revival for the EU is “bad” (or “worse”) for non-IE-language-speakers like Finnish, Hungarian, Estonian, Basque or Maltese peoples. In fact, anyone who had taken a look at our website, or had made a quick search about me, would have found that I began this project of PIE revival to defend European languages (at least minority languages, as national or official languages are already well protected) against the European Union’s English officious imperium and English-German-French official triumvirate. Also, if we left PIE revival, only some languages (the official, i.e. national ones, 25 today) would get EU support, while the rest just die out or resist with some regional or private support. With Modern Indo-European, on the other hand, there will only be one official language supported by the European Union, and the rest really equal in front of each other and the Union, be it English, Maltese, Basque, Saami or Piedmontese. Nowadays, English is the language spoken in institutions, Maltese has an official status before the EU, while Saami is official in its country, Basque is only official in its territory, and Piedmontese, Asturian, Breton, and the majority of EU regional languages are only privately and locally defended. Nevertheless, one only has to say “supporting Indo-European is what Nazis did, PIE revival is racist and wants to destroy non-Indo-European peoples and cultures”; and, there you are: nothing proven, nothing reasoned, but the simplest and most efficient FUD you can find to counter the thousand arguments in favour of this revival project.

However unnecessary and unfruitful it might seem, I still discuss – or even directly look for debate -, because I get a benefit of such long, active pauses from my study, unlike those tiny passive TV- or radio-pauses I insert between study hours, especially in these stressful exam periods. Indeed I can find something to discuss in any website at any time, but I’m generally interested in debating these language political options. Nevertheless, I find it difficult to understand why some people get mad (at me, the project, or even the association or the whole world), when in fact taking part on any discussion is freely accepted by all of us, and it’s me who put new ideas and proposals on the table, and the others who just have to criticize them…

Something valuable for life I learned from psychology (possibly the only thing…) is about Chomsky’s reaction on Skinner’s comments: my professor (close to Freudian psychoanalysis), who told us the story – I hope I got it well, I cannot find it out there – thought it was Skinner who “won” the debate, by answering to Chomsky’s criticism, who in turn had criticized Skinner’s work, Verbal Behaviour, for his “scientistic”, not scientific, concept of the human mind. In fact, the younger Chomsky had just applied science to psychology (a need that psychology still has), simplifying the understanding of mind with a strict cognitive view, and criticizing some traditional views that psychologists accepted as ‘normal’. Skinner and those who followed his behavioural school of thought overreacted, mostly based on the belief that Chomsky’s reasons were against their lives and professional options, when in fact reason and opinion are in different planes. Chomsky, instead of entering the flame (yes, trolling existed back in the 60’s) did nothing. When asked years later, about why he didn’t reply as expected to all that criticism, he just said: “they missed the point”; he said what he had to say, criticized what he wanted, proposed an alternative, and left the discussion. And still, even by not answering, cognitive revolution provoked a shift in American psychology between the 1950s through the 1970s from being primarily behavioral to being primarily cognitive.

If you want to debate about opinions – be it PIE revival, Europeanism, general politics, Star Trek or the sex of angels -, entering into unending criticisms and personal attacks, that’s OK; but you should do it if and when you want, as I only do it because I obtain something beneficial, having a good time, laughing a little bit, relaxing from study, thinking about interesting reasons that might appear for or against my views or ideas, etc. And you should do it to get something in (re)turn, be it that same stress relief I (and most people) get, or other personal or professional benefits whatsoever. If not, if maybe you are getting more stressed trying to “convince” me or others, to “make us change our minds” with great one-minute ‘reasons’, by discussing directly your opinions as if they were ‘true‘, then you are clearly “missing the point” (using Chomsky’s words) with these discussions, and – as our latest Esperantist commenter (Mr. Janoski) puts it – “losing your time”, “trying to understand” something…
