Mitogenomes show Longobard migration was socially stratified and included females

New bioRxiv preprint A genetic perspective on Longobard-Era migrations, by Vai et al. (2018).

Interesting excerpts (emphasis mine):

In this study we sequenced complete mitochondrial genomes from nine early-medieval cemeteries located in the Czech Republic, Hungary and Italy, for a total of 87 individuals. In some of these cemeteries, a portion of the individuals are buried with cultural markers in these areas traditionally associated with the Longobard culture (hereby we refer to these cemeteries as LC), as opposed to burial communities in which no artifacts or rituals associated by archaeologists to Longobard culture have been found in any graves. These necropolises, hereby referred as NLC, may represent local communities or other Barbaric groups previously migrated to this region. This extended sampling strategy provides an excellent condition to investigate the degree of genetic affinity between coeval LC and NLC burials, and to shed light on early-medieval dynamics in Europe.

Social rank

There is also no clear geographical structure between samples in our dataset, with individuals from Italy, Hungary and Czech Republic clustering together. However, the first PC clearly separates a group of 12 LC individuals found at Szólád, Collegno and Mušov from a group composed by both LC and NLC individuals. The same pattern is also found when pairwise differences among individuals are plotted by multidimensional scaling (…)

The presence in this group of LC sequences belonging to macrohaplogroups I and W, commonly found at high frequencies in northern Europe (e.g. Finland 32), suggests (although certainly does not prove) the existence of a possible link between these 12 LC individuals and northern Europe. The peculiarity of this group is strengthened by archaeological information from the Szólád cemetery, where 8 of the 12 individuals in this group originated, indicating that all these samples were found buried with typical Longobard artifacts and grave assemblages. We do not find the same tight association for the 3 samples from Collegno, where the 3 graves are indeed devoid of evident Germanic cultural markers; however they are not placed in a separate and marginal location—as for the tombs without grave goods found in Szólád —but among graves with wooden chambers and weapons. It is worth noting that weapon burials were quite scarce in 5th century Pannonia and 6th century Italy (e.g. Goths never buried weapons), and an increase in weapon burials started in Italy only after the Longobard migration. In this light, the individuals buried in this manner may have been members of the same community as well, but belonging to the lowest social level. This social condition could explain the absence of artifacts and could be related to mixed marriages, whose offspring had an inferior social rank. Finally, this group also includes an individual from the Musov graveyard. This finding is particularly interesting in light of the fact that the Musov necropolis has been only tentatively associated with Longobard occupation (see Supplementary Text for details), based on the presence of but a few archaeological markers.

Female migration

We hence estimated that about 70% of the lineages found in Collegno actually derived from the Hungarian LC groups, in agreement with previous archaeological and historical hypotheses. This supports the idea that the spread of Longobards into Italy actually involved movements of fairly large numbers of people, who gave a substantial contribution to the gene pool of the resulting populations. This is even more remarkable thinking that, in many studied cases, military invasions are movements of males, and hence do not have consequences at the mtDNA level. Here, instead, we have evidence of changes in the composition of the mtDNA pool of an Italian population, supporting the view that immigration from Central Europe involved females as well as males.

When Bell Beakers mixed with Eneolithic Europeans: Pömmelte and the Europe-wide concept of sanctuary

pommelte-enclosure

Recent open access paper The ring sanctuary of Pömmelte, Germany: a monumental, multi-layered metaphor of the late third millennium BC, by Spatzier and Bertemes, Antiquity (2018) 92(363):655-673.

Interesting excerpts (emphasis mine):

In recent decades, evidence has accumulated for comparable enclosures of later dates, including the Early Bronze Age Únětice Culture between 2200 and 1600 BC, and thus into the chronological and cultural context of the Nebra sky disc. Based on the analysis of one of these enclosure sites, recently excavated at Pömmelte on the flood plain of the Elbe River near Magdeburg, Saxony-Anhalt, and dating to the late third millennium BC

The main occupation began at 2321–2211 cal BC, with the stratigraphically earliest features containing exclusively Bell Beaker finds. Bell Beaker ceramics continue after 2204–2154 cal BC (boundary occupation I/II), although they were probably undecorated, but are now complemented by Únětice Culture (and other Early Bronze Age) types. At this time, with features common to both cultures predominate. Only contexts dating to the late main occupation phase (late phase II) and thereafter contained exclusively Únětice Culture finds. Evidently, the bearers of the Bell Beaker Culture were the original builders of the enclosure. During a second phase of use, Final Neolithic and Early Bronze Age cultures coexisted and intermingled. The material remains, however, should not be taken as evidence for successive groups of differing archaeological cultures, but as witnesses to a cultural transition from the Bell Beaker Culture to the Únětice Culture (Spatzier 2015). The main occupation ended 2086–2021 cal BC with the deconstruction of the enclosure; Bell Beaker finds are now absent. Finally, a few features (among them one shaft) and radiocarbon dates attest the sporadic re-use of the site in a phase of abandonment/re-use that ended 1636– 1488 cal BC.

Cultural sequence and chronological model of the Pömmelte enclosure’s occupation (dates in 1σ-precision) (designed by André Spatzier).

How the above-ground structures possibly influenced perception may reveal another layer of meaning that highlights social functions related to ritual. While zone I was disconnected from the surroundings by a ‘semi-translucent’ post-built border, zones II/III were separated from the outside world by a wooden wall (i.e. the palisade), and zone III probably separated individuals from the crowd gathered in zone II. Accessing the interior or centre therefore meant passing through transitional zones, to first be secluded and then segregated. Exiting the structure meant re-integration and re-connection. The experience possibly induced when entering and leaving the monument reflects the three stages of ‘rites of passage’ described by van Gennep (1909): separation, liminality and incorporation. The enclosure’s outer zone(s) represents the pre- and post-liminal phase; the central area, the liminal phase. Seclusion and liminality in the interior promoted a sense of togetherness, which can be linked to Turner’s “communitas” (1969: 132–33). We might therefore see monuments such as the Pömmelte enclosure as important communal structures for social regulation and the formation of identity.

ring-sanctuary-of-pommelte
Layers of meaning of the Pömmelte enclosure as deduced from the archaeological record (design by André Spatzier).

(…) The long-term stability of these connotations must be emphasised. As with the tradition of making depositions, these meanings were valid from the start of the occupation — c. 2300 BC — until at least the early period following the deconstruction event, c. 2050 BC. While the spatial organisation and the solar alignment of the main entrances were maintained throughout the main occupation, stone axes and ‘formal’ graves indicate the continuation of the spatial concepts described above until the twentieth to nineteenth centuries BC.

These layers of meaning mirror parallel concepts of space including, although not necessarily restricted to, the formation of group identities (see Hansen & Meyer 2013: 5). They can perhaps be better understood as a ‘cosmological geography’ manifested in the symbolism of superimposed levels of conceptual ideas related to space and to certain cardinal points (Figure 8). This idea is closely related to Eliade’s (1959: 29–36) understanding of “organized — hence comicized — territory”, that is territory consecrated to provide orientation within the homogeneity of the chaotic ‘outside world’, and the equivalence of spatial consecration and cosmogony. Put differently, the Pömmelte enclosure can be interpreted as a man-made metaphor and an icon of the cosmos, reflecting the Weltanschauung (a comprehensive conception of the world) of the people who built and used it. By bringing together Eliade and Rappaport’s ideas of meaningfulness in relation to religious experience (Rappaport 1999: 391–95), it may be argued that Pömmelte was a place intended to induce oneness with the cosmos. In combining multiple layers that symbolically represent different aspects of life (first-ordermeaning), the enclosure became an icon metaphorically representing the world (second-order-meaning). As this icon was the place to reaffirm life symbolism ritually, through their actions, people perhaps experienced a sense of rootedness in, or unity with, the cosmos (highest-order-meaning). Although we can only speculate about the perceptions of ancient people, such a theory aiming to describe general principles of religious experience can provide insight.

Conclusions

The circular enclosure of Pömmelte is the first Central European monumental complex of primarily sacred importance that has been excavated and studied in detail. It reveals aspects of society and belief during the transition from the Final Neolithic to the Early Bronze Age, in the second half of the third millennium BC. Furthermore, it offers details of ritual behaviour and the way that people organised their landscape. A sacred interior was separated from the profane environment, and served as a venue for rites that secured the continuity of the social, spiritual and cosmic order. Ancestor worship formed another integral part of this: a mound-covered burial hut and a square-shaped ditch sanctuary (located, respectively, within and near the enclosure’s south-eastern sector; cf. Figure 2)—dating to 2880–2580 cal BC and attributed to the Corded Ware Culture (Spatzier 2017a: 235–44)—suggest that this site was deliberately chosen. With construction of the ring sanctuary, this place gained an immense expansion in meaning—comparable to Stonehenge. Through architectural transformation, both of these sites developed into sanctuaries with increasingly complex religious functions, including in relation to the cult of the dead. The cosmological and social functions, and the powerful symbolism of the Nebra sky disc and hoard (Meller 2010: 59–70), are reflected in Pömmelte’s monumental architecture.

All of these features—along with Pömmelte’s dating, function and complex ring structure—are well documented for British henge monuments (Harding 2003; Gibson 2005). The continuous use of circular enclosures in Central Europe from around 3000– 1500 BC remains to be confirmed, but strong evidence indicates usage spanning from the fifth to the first millennia BC (Spatzier 2017a: 273–96). From 2500 BC onwards, examples in Central Europe, Iberia and Bulgaria (Bertemes 2002; Escudero Carrillo et al. 2017) suggest a Europe-wide concept of sanctuary. This indicates that in extensive communication networks at the beginning of bronze metallurgy (Bertemes 2016), intellectual and religious contents circulated alongside raw materials. The henge monuments of the British Isles are generally considered to represent a uniquely British phenomenon, unrelated to Continental Europe; this position should now be reconsidered. The uniqueness of Stonehenge lies, strictly speaking, with its monumental megalithic architecture.

The Classical Bell Beaker heritage

No serious scholar can argue at this point against the male-biased East Bell Beaker migrations that expanded the European languages related to Late Proto-Indo-European-speaking Yamna (see David Reich’s comments), and thus most likely North-West Indo-European – the ancestor of Italo-Celtic, Germanic, and Balto-Slavic, apart from Pre-Celtic IE in the British Isles, Lusitano-Galician in Iberia, or Messapic in Italy (see here a full account).

With language, these migrants (several ten thousands) brought their particular Weltanschauung to all of Western, Central, and Northern Europe. Their admixture precisely in Hungary shows that they had close interactions with non-Indo-European peoples (genetically related to the Globular Amphorae culture), something that we knew from the dozens of non-Indo-European words reconstructed exclusively for North-West Indo-European, apart from the few reconstructed non-Indo-European words that NWIE shares with Palaeo-Balkan languages, which point to earlier loans from their ancestors, Yamna settlers migrating along the lower Danube.

It is not difficult to imagine that the initial East Bell Beaker group shared a newly developed common cosmological point of view that clashed with other neighbouring Yamna-related worldviews (e.g. in Balkan EBA cultures) after the cultural ties with Yamna were broken. Interesting in this respect is for example their developed (in mythology as in the new North-West Indo-European concept) *Perkwūnos, the weather god – probably remade (in language as in concept) from a Yamna minor god also behind Old Indian parjányas, the rain god – as one of the main gods from the new Pantheon, distinct from *Dyēus patēr, the almighty father sky god. In support of this, the word *meldh-n- ‘lightning’, behind the name of the mythological hammer of the weather god (cf. Old Norse Mjǫllnir or Latvian Milna), was also a newly coined North-West Indo-European term, although the myth of the hero slaying the dragon with the magical object is older.

Circular enclosures are known in Europe since the Neolithic. Also, the site selected for the Pömmelte enclosure had been used to bury Corded Ware individuals some centuries before its construction, and Corded Ware symbolism (stone axe vs. quern) is seen in the use given by Bell Beakers and later Únětice at this place. All this and other regional similarities between Bell Beakers and different local cultures (see here an example of Iberian Bell Beakers) points to syncretism of the different Bell Beaker groups with preceding cultures in the occupied regions. After all, their genealogical ancestors included also those of their maternal side, and not all encountered males disappeared, as is clearly seen in the resurge of previous paternal lineages in Central-East Europe and in Scandinavia. The admixture of Bell Beakers with previous groups (especially those of similar steppe-related ancestry from Corded Ware) needs more complex analyses to clarify potential early dialectal expansions (read what Iosif Lazaridis has to say).

The popular “big and early” expansions

These syncretic trends gave rise to distinct regional cultures, and eventually different local groups rose to power in the new cultural regions and ousted the old structures. Social norms, hierarchy, and pantheons were remade. Events like this must have been repeated again and again in Bronze and Iron Age Europe, and in many cases it was marked by a difference in the prevailing archaeological culture attested, and probably accompanied by certain population replacements that will be seen with more samples and studies of fine-scale population structure.

Some of these cultural changes, marked by evident haplogroup or admixture replacement, are defined as a ‘resurge’ of ancestry linked to previous populations, although that is obviously not equivalent to a resurge of a previous cultural group, because they usually represent just a successful local group of the same supraregional culture with a distinct admixture and/or haplogroup (see e.g. resurge of R1a-Z645 in Central-East European Bronze Age). Social, religious, or ethnic concepts may have changed in each of these episodes, along with the new prestige dialect.

NOTE. A recent open access paper on two newly studied Middle Bronze Age inhumations from Stonehenge give an interesting idea of potential differences in social identities, in ancestry and geographic origin (which characterize ethnicity) may have been marked by differences in burial ceremonies: Lives before and after Stonehenge: An osteobiographical study of four prehistoric burials recently excavated from the Stonehenge World Heritage Site, by Mays et al. Journal of Archaeological Science: Reports (2018) 20:692-710.

This must have happened then many times during the hundreds (or thousands in some cases) of years until the first attestation of a precise ancient language and culture (read e.g. about one of the latest branches to be attested, Balto-Slavic). Ancient language contacts, like substrates or toponymy, can only rarely be detected after so many changes, so their absence (or the lack of proper studies on them) is usually not relevant – and certainly not an argument – in scholarly discussions. Their presence, on the other hand, is a proof of such contacts.

chalcolithic_late_Europe_Bell_Beaker
Diachronic map of Late Copper Age migrations including Classical Bell Beaker (east group) expansion from central Europe ca. 2600-2250 BC

We have dozens of papers supporting Uralic dialectal substrate influence on Pre-Germanic, Proto-Balto-Slavic, and Pre- and Proto-Indo-Iranian (and even Proto-Celtic), as well as superstrate influence of Palaeo-Germanic (i.e. from Pre- to Proto-Germanic) and Proto-Balto-Slavic into Proto-Finno-Saamic, much stronger than the Indo-Iranian adstrate influence on Finno-Ugric (see the relative importance of each influence) which locates all these languages and their evolution to the north and west of the steppe (with Proto-Permic already separated, in North-East Europe, as is Proto-Ugric further east near the Urals), probably around the Baltic and Scandinavia after the expansion of Bell Beakers. These connections have been known in linguistics for decades.

Apart from some early 20th century scholars, only a minority of Indo-Europeanists support nowadays an Indo-European (i.e. centum) substrate for Balto-Slavic, to keep alive an Indo-Slavonic group based on a hypothetical 19th century Satem group; so e.g. Holzer with his Temematic, and Kortlandt supporting him, also with some supposed Indo-European substrate with heavy non-Indo-European influence for Germanic and Balto-Slavic, that now (thanks mainly to the views of the Copenhagen group) have been linked to the Corded Ware culture, as it has become clear even to them that Bell Beakers expanded North-West Indo-European.

NOTE. The Temematic etymologies have been (all of them) fully dismissed e.g. in Matasović (2013). I have already explained why an Indo-Slavonic group from Sredni Stog is not tenable, and genetics (showing Late PIE only from Yamna expansions) is proving that, too.

For their part, only a minority among Uralicists, such as Kuz’mina, Parpola or Häkkinen, believe in an ‘eastern’ origin of Uralic languages, around the Southern Urals. Genomic finds – like their peers – are clearly not supporting their views. But even if we accept this hypothesis, there is little space beyond Abashevo and related East Corded Ware cultures after the recent papers on Corded Ware and Fennoscandian samples. And yet here we are:

The Copenhagen “Homeland” interactive map

copenhagen-group-map
Brought to you by the Copenhagen fantasy map series, Indo-Europeans after (no, really, after) the expansion of Yamna settlers in Hungary ca. 2700 BC: Yamna settlers have magically disappeared. Yamna-related Balkan EBA cultures and the hundreds of Yamna kurgans around the Lower Danube and in Hungary up to Saxony-Anhalt do not exist. Dat huge mythical Middle Dnieper territory lasting (unchanged) for a thousand years, in sooo close contact with Yamna territory (so beautifully ‘linked’ together that they must have been BFFs and admixed!). Uralic Mesolithic hunter-gatherers resisting IE invasions in Volosovo for 1,500 years like Asterix’ Gaulish village against the Romans. Tiny pockets of Bell Beakers will eventually emerge from (surprise!) Corded Ware territories beautifully scattered over Central and Northern Europe (unlike those eastern CWC mega-regions). And, of course, you can almost see Kroonen & Iversen’s Kurgan Pre-Germanic mixing already with their agricultural substrate TRB precisely in full-IE Denmark (quite appropriate for the Danish school). And sheep symbols representing wool finds, for no reason. A great map to mock for years to come, with each new genetic paper.

The new propaganda tool GIS timeline map of the Copenhagen group:

  • consciously ignores Yamna settlers along the Danube, in the Balkans, and in Hungary, and initial East Bell Beakers, i.e. the obvious origin and expansion of North-West Indo-Europeans, but in contrast magnifies (and expands in time) regions for Sredni Stog / Corded Ware cultures (which suggests that this is yet another absurd attempt to revive the theories of the Danish school…);
  • substitutes arrows for Kron-like colors (where danger red = Indo-European) with the same end result of many other late 20th century whole-Europe Kurgan maps, linking Sredni Stog and Corded Ware with Yamna, but obviating the precise origin of Corded Ware peoples (is it Sredni Stog, or is it that immutable Middle Dnieper group? is it West Yamna, or Yamna Hungary? is it wool, or is it wheels?);
  • relegates Uralic speakers to a tiny corner, a ‘Volosovo’ cultural region, thus near Khvalynsk/Yamna (but not too much), that miraculously survives surrounded by all-early-splitting, all-Northern Eneolithic Indo-Europeans, thus considering Uralic languages irrelevant not only to locate the PIE Urheimat, but also to locate their own homeland; also, cultures identified in color with Uralic speakers expand until the Iron Age with enough care not to even touch in the map one of the known R1a samples published to date (because, for some people, apparently R1a must be Indo-European); and of course N1c or Siberian ancestry are irrelevant, too;
  • and adds findings of wheels and wool probably in support of some new ideas based on yet another correlation = causation argument (that I cannot then properly criticize without access to its reasoning beyond cute SmartArt-like symbols) similar to their model – already becoming a classic example of wrong use of statistical methods – based on the infamously named Yamnaya ancestral component, which is obviously still used here, too.

The end result is thus similar to any other simplistic 1990s Gimbutas (or rather the recently radicalized IE Sredni Stog -> Corded Ware -> BBC version by the Danish workgroup) + 2000s R1a-map + 2010s Yamnaya ancestry; but, hard to believe, it is published in mid-2018. A lot of hours of senseless effort, because after its publication it becomes ipso facto outdated.

For comparison of Yamna and Bell Beaker expansions, here is a recent simplistic, static (and yet more accurate) pair of maps, from the Reich Lab:

corded-ware-bell-beaker
Cultural maps from Eneolithic and Chalcolithic cultures in Wang et al. (2018).

If the Copenhagen group keeps on pushing Gimbutas’ long ago outdated IE Sredni Stog -> Corded Ware theory as modified by Kristiansen, with their recently invented Corded Ware -> Bell Beaker model in genetics, at some point they are bound to clash with the Reich-Jena team, which seems to have less attachment to the classic Kurgan model and the wrong interpretations of the 2015 papers, and that would be something to behold. Because, as Cersei would say: “When you play the game of thrones, you win or you die. There is no middle ground.” And when you play the game of credibility, after so many, so wrong publications, well…

NOTE. I have been working on a similar GIS tool for quite some time, using my own maps and compiled genetic data, which I currently only use for my 2018 revision of the Indo-European demic diffusion model. Maybe within some weeks or months I will be able to publish the maps properly, after the revised papers. It’s a pitty that so much work on GIS and analysis with genetic data and cultural regions has to be duplicated, but I intend to keep some decent neutrality in my revised cultural maps, and this seems impossible at this point with some workgroups who have put all their eggs in one broken basket…

Mitogenomes from the middle of the Merovingian period in the Lorraine region

herange-burial

Investigating the kinship between individuals deposited in exceptional Merovingian multiple burials through aDNA analysis: The case of Hérange burial 41 (Northeast France), by Deguilloux et al. Journal of Archaeological Science: Reports (2018) 20:784-790.

Interesting excerpts (emphasis mine):

The Merovingian period in Northeast France (developing from 440/450 to 700/710 CE; Legoux et al., 2004) represents [a case of multiple burial], where a large majority of the types of deposits encountered consists of individual burials. In this context, whereas hundreds of individual burials are known, the syntheses recently conducted have enabled the inventory of only six multiple burials (Lefebvre and Lafosse, 2016). These observations naturally raised questions about the exceptional circumstances that led the members of the community to set up such unusual burials. The archaeological site of Hérange, excavated in 2014 (Lorraine, Grand Est region; Fig. S1), holds a key position in the debate surrounding the interpretation of multiple burials during the Merovingian period since it contains one of these rare multiple burials: burial 41, which was dated through archaeological material to the period 530–640 CE.

(…) The biological analysis of the human remains recovered in the second burial (“burial 41”) enabled the demonstration of the combined presence of a woman of approximately 40 years old (A) and three immature individuals, including a 4–5-year-old child (B), a 14–16-year-old teenager (C) and a 2,5–3-month-old infant (D) (Lefebvre and Lafosse, 2016) (Fig. 1). Since rare multiple burials described for the Merovingian period in Northeast France mainly contained two or rarely three deceased, the discovery of a burial grouping four individuals reinforced its exceptional nature. (…) Intriguingly, great care was observed in the treatment of the dead, as illustrated through a special arrangement of the deceased in the grave (Fig. 1). Indeed, the woman A occupied a central position in the grave, with her left arm covering part of the body of child D, her right arm covering the torso of child B and her right hand covering the legs of children B and C. Several arguments, such as the close contact or the imbrication of the bones of individuals A, B and C, have attested to the simultaneity of their deposits in the burial (Lefebvre and Lafosse, 2016).

Geographic distribution of the extant European individuals sharing mitochondrial haplotypes with the Hérange human remains.

Interestingly, studies have demonstrated an important chronological homogeneity for the rare multiple burials discovered for the Merovingian period in the Lorraine region (Lefebvre and Lafosse, 2016). The collected data support the existence of an epiphenomenon arisen around the middle of the Merovingian period and that may have linked the multiple burials to (i) a funerary “fashion trend” for a special group of the community, (ii) an increase in cases of violence or (iii) an epidemic crisis linked to infectious disease. In other Lorraine sites, none of the available indices permitted the specification of the cause of death for the individuals recovered in these specific burials. The deceased could well have died of natural causes, violent acts or infectious diseases that had left no visible evidence on the skeletal.

merovingian-y-chromosome
Nuclear data (Y chromosome SNPs and nuclear STRs) typed on the four Hérange human remains (STRs alleles shown in grey were not fully replicated).

The aDNA analyses conducted on the four individuals discovered in the exceptional multiple burial 41 from Hérange (Lorraine) have demonstrated strong biological links between three individuals. Notably, we could propose that the woman A was the mother of the two immatures B and D deposited just besides her whereas she was not genetically closely related to the teenager C deposited along her legs. Consequently, we propose that the special arrangement of the deceased in the grave clearly reflected the degree of biological links between the deposited individuals. In Hérange, the bereaved were well aware of kinship among the deceased, wanted to express this close linkage through their relative location within the burial, and intentionally arranged body positions consequently. In conclusion, the collected archaeological, archaeo-anthropological and genetic data suggest that the special setup of the multiple burial 41 in the Hérange necropolis and the great care in the treatment of the dead, could be explained by the contemporaneous death of the four related individuals. Data gathered for other archaeological sites from the region or in Germany suggested an epidemic crisis (plague epidemic?) during the middle of the Merovingian period that may explain the contemporaneous death of related individuals living in close contact and easily sharing pathogens.

Kortlandt: West Indo-Europeans along the Danube, Germanic and Balto-Slavic share a Corded Ware substrate

copper-age-early_yamna-corded-ware

New paper (behind paywall) The Expansion of the Indo-European Languages, by Frederik Kortlandt, JIES (2018) 46(1 & 2):219-231.

Abstract:

When considering the way the Indo-Europeans took to the west, it is important to realize that mountains, forests and marshlands were prohibitive impediments. Moreover, people need fresh water, all the more so when traveling with horses. The natural way from the Russian steppe to the west is therefore along the northern bank of the river Danube. This leads to the hypothesis that the western Indo-Europeans represent successive waves of migration along the Danube and its tributaries. The Celts evidently followed the Danube all the way to southern Germany. The ancestors of the Italic tribes, including the Veneti, may have followed the river Sava towards northern Italy. The ancestors of Germanic speakers apparently moved into Moravia and Bohemia and followed the Elbe into Saxony. A part of the Veneti may have followed them into Moravia and moved along the Oder through the Moravian Gate into Silesia. The hypothetical speakers of Temematic probably moved through Slovakia along the river Orava into western Galicia. The ancestors of speakers of Balkan languages crossed the lower Danube and moved to the south. This scenario is in agreement with the generally accepted view of the earliest relations between these branches of Indo-European.

The western Indo-European vocabulary in Baltic and Slavic is the result of an Indo-European substratum which contained an older non-Indo-European layer and was part of the Corded Ware horizon. The numbers show that a considerable part of the vocabulary was borrowed after the split between Baltic and Slavic, which came about when their speakers moved westwards north and south of the Pripet marshes. These events are older than the westward movement of the Slavs which brought them into contact with Temematic speakers. One may conjecture that the Venedi occupied the Oder basin and then expanded eastwards over the larger part of present-day Poland before the western Balts came down the river Niemen and moved onwards to the lower Vistula. We may then identify the Venedic expansion with the spread of the Corded Ware horizon and the westward migration of the Balts and the Slavs with their integration into the larger cultural complex. The theory that the Venedi separated from the Veneti in the upper Sava region and moved through Moravia and Silesia to the Baltic Sea explains the “im Namenmaterial auffällige Übereinstimmung zwischen dem Baltikum und den Gebieten um den Nordteil der Adria” (Udolph 1981: 61). The Balts probably moved in two stages because the differences between West and East Baltic are considerable.

Instead of reinterpreting his views in light of the recent genetic finds, Kortlandt tries to mix in this paper his own old theories (see his paper Baltic, Slavic, Germanic) with the recent interpretations of genetic papers, using also dubious secondary sources – e.g. Iversen and Kroonen (2017) or Klejn (2017) [see here, and here] – which, in my opinion, creates a potentially dangerous circular reasoning.

For example, even though he criticizes the general stance of recent genetic papers with regard to Proto-Indo-European dialectalization and expansion as too early, and he supports the Danube expansion route, he nevertheless follows their interpretations in accepting that Corded Ware was Indo-European (following the newest model proposed by Anthony):

The [Yamnaya] penetrated central and northern Europe from the lower Danube through the Carpathian basin, not from the east. The Carpathian basis was evidently the cradle of the Corded Ware cultures, where the descendants of the Yamnaya mixed with the local early farmers before proceeding to the north. The development has a clear parallel in the Middle Ages, when the Hungarians mixed with the local Slavic populations in the same territory (cf. Kushniarevich & al. 2015).

He still follows his good old Indo-Slavonic group in the east, but at the same time maintains Kallio’s view that there were no early Uralic loanwords in Balto-Slavic, and also Kallio’s (and the general) view that there were close contacts with PIE and Pre-Proto-Indo-Iranian…

NOTE. The latest paper on Eurasian migrations by Damgaard et al. (Nature 2018), which shows mainly Proto-Iranians dominating over East Europe after the Early Bronze Age, have left still fewer space for a Proto-Balto-Slavic group emerging from the east.

Also, he asserts the following, which is a rather weird interpretation of events:

It appears that the Corded Ware horizon spread to southern Scandinavia (cf. Iversen & Kroonen 2017) but not to the Baltic region during the Neolithic.

“However, we also find indications of genetic impact from exogenous populations during the Neolithic, most likely from northern Eurasia and the Pontic Steppe. These influences are distinct from the Anatolian-farmer-related gene flow found in Central Europe during this period.”

It follows that the Indo-Europeans did not reach the Baltic region before the Late Neolithic. The influx of non-local people from northern Eurasia may be identified with the expansion of the Finno-Ugrians, who came into contact with the Indo-Europeans as a result of the eastward expansion of the latter in the fourth millennium. This was long before the split between Balto-Slavic and Indo-Iranian.

In the Late Neolithic there was “a further population movement into the regions surrounding the Baltic Sea” that was “accompanied by the first evidence of extensive animal husbandry in the Eastern Baltic”, which “suggests import of the new economy by an incoming steppe-like population independent of the agricultural societies that were already established to the south and west of the Baltic Sea.” (Mittnik & al. 2018). These may have been the ancestors of Balto-Slavic speakers. At a later stage, the Corded Ware horizon spread eastward, giving rise to farming ancestry in Eastern Baltic individuals and to a female gene-flow from the Eastern Baltic into Central Europe (ibidem).

He is a strong Indo-Uralic supporter, and supports a parallel Indo-European – Uralic development in Eastern Europe, and (as you can read) he misunderstands the description of population movements in the Baltic region, and thus misplaces Finno-Ugric speakers as Eurasian migrants arriving in the Baltic from the east during the Late Neolithic, before the Corded Ware expansion, which is not what the cited papers implied.

NOTE. Such an identification of westward Neolithic migrations with Uralic speakers is furthermore to be rejected following the most recent paper on Fennoscandian samples.

He had previously asserted that the substrate common to Germanic and Balto-Slavic is Indo-European with non-Indo-European substrate influence, so I guess that Corded Ware influencing as a substrate both Germanic and Balto-Slavic is the best way he could put everything together, if one assumes the widespread interpretations of genetic papers:

Thus, I think that the western Indo-European vocabulary in Baltic and Slavic is the result of an Indo-European substratum which contained an older non-Indo-European layer and was part of the Corded Ware horizon. The numbers show that a considerable part of the vocabulary was borrowed after the split between Baltic and Slavic, (…)

NOTE. It is very likely that this paper was sent in late 2017. That’s the main problem with traditional publications including the most recent genetic investigation: by the time something gets eventually published, the text is already outdated.

I obviously share his opinion on precedence of disciplines in Indo-European studies:

The methodological point to be emphasized here is that the linguistic evidence takes precedence over archaeological and genetic data, which give no information about the languages spoken and can only support the linguistic evidence. The relative chronology of developments must be established on the basis of the comparative method and internal reconstruction. The location of a reconstructed language can only be established on the basis of lexical and onomastic material. On the other hand, archaeological or genetic data may supply the corresponding absolute chronology. It is therefore incorrect to attribute cultural influences in southern Scandinavia and the Baltic region in the third millennium to Germanic or Baltic speakers because these languages did not yet exist. While the Italo-Celtic branch may have separated from its Indo-European neighbors in the first half of the third millennium, Proto-Balto-Slavic and Proto-Indo-Iranian can be dated to the second millennium and Proto-Germanic to the end of the first millennium BC (cf. Kortlandt 2010: 173f., 197f., 249f.). The Indo-Europeans who moved to southern Scandinavia as part of the Corded Ware horizon were not the ancestors of Germanic speakers, who lived farther to the south, but belonged to an unknown branch that was eventually replaced by Germanic.

I hope we can see more and more anthropological papers like this, using traditional linguistics coupled with archaeology and the most recent genetic investigations.

Pre-Germanic born out of a Proto-Finnic substrate in Scandinavia

indo-european-yamnaya-corded-ware

A commenter, Old Europe, drew my attention to the Uralic (Finnic-Saamic) substrate in Germanic proposed by Schrijver in Chapter V. Origins of Language Contact and the Origins of the Germanic Languages, Routledge (2014).

I wanted to share here some interesting excerpts (emphasis mine):

NOTE. I have avoided many detailed linguistic discussions. You should read the whole chapter to check them out.

The origins of the Germanic subfamily of Indo-European cannot be understood without acknowledging its interactions with a language group that has been its long-time neighbour: the Finnic subgroup of the Uralic language family. Indo-European and Uralic are linked to one another in two ways: they are probably related to one another in deep time — how deep is impossible to say3 — and Indo-European has been a constant source from which words were borrowed into Uralic languages, from the fourth millennium BC up to the present day.4 The section of the Uralic family that has always remained in close proximity to the Indo-European dialects which eventually turned into Germanic is Finnic. I use the term Finnic with a slightly idiosyncratic meaning : it covers the Finno-Saamic protolanguage and both of its children, Saami and Balto-Finnic.(…)

finnic-family-tree-schrijver
Schrijver (2014). The Finnic family tree (simplified)

Linguistically, the relationship between Indo-European and Uralic has always been asymmetrical. While hundreds of loanwords flowed into Uralic languages from Indo-European languages such as Germanic, Balto-Slavic, Iranian, and Proto-Indo-European itself, hardly any Uralic loanwords have entered the Indo-European languages (apart from a few relatively late dialectal loans into e.g. Russian and the Scandinavian languages). This strongly suggests that Uralic speakers have always been more receptive to ideas coming from Indo-European–speaking areas than the other way around. This inequality probably began when farming and the entire way of life that accompanies it reached Uralic-speaking territory via Indo-European–speaking territory, so that Uralic speakers, who traditionally were hunter-gatherers of the mixed and evergreen forest zone of northeastern Europe and gradually switched to an existence as sedentary farmers, were more likely to pick up ideas and the words that go with them from Indo-European than from anywhere else.

Farming requires a different mind-set from a hunter-gatherer existence. Farmers are generally sedentary, model the landscape, and have an agricultural calendar to determine their actions. Hunter-gatherers of the northern forest zone are generally nomadic, and rather than themselves modelling the natural environment they are modelled by it: their calendar depends on when and where a particular natural resource is available.(…)

All of this is no doubt a simplification of the thousands of years of associations between speakers of Uralic and speakers of Indo-European, but the loanword evidence strongly suggests that by and large relations between the two groups were highly unequal. The single direction in which loanwords flowed, and the mass of loanwords involved, can be compared with the relation between Latin and the vernacular languages in the Roman Empire, almost all of which disappeared in favour of Latin. It is therefore certain that groups of Uralic speakers switched to Indo-European. The question is whether we can trace those groups and, more particularly, whether Finnic speakers switching to Indo-European were involved in creating the Indo-European dialect we now know as Germanic.

Convergence of Finnic and Germanic

What both have in common is that the sound structures of Finnic and Germanic, which started from very different beginnings, apparently came to resemble one another significantly. If that is what we observe, we must conclude that both languages converged as a result of contact.

During the approximately five to six millennia that separate Proto-Uralic from Modern Finnish, there was only one episode during which the consonantal system underwent a dramatic overhaul. This episode separates the Finno-Saamic protolanguage, which is phonologically extremely conservative, from the Balto-Finnic protolanguage, which is very innovative.

finno-samic-consonants

By the time Finno-Saamic developed into Balto-Finnic, the consonant system was very different:

balto-finnic-consonants

In Balto-Finnic, the entire palatal series has been lost, apart from j, and the contrast between dentals and alveolars has disappeared: out of three different s-sounds only one remains. The fricatives ð and γ have been lost, and so has the velar nasal ŋ. The only increase has been in the number of long (geminate) consonants by the appearance of ss, mm, nn, and ll. The loss of separate alveolar and palatal series and the disappearance of ŋ could be conceived as convergences towards Proto-Germanic, which lacked such consonants. This is not obvious for the loss of the voiced fricatives γ, ð, which Proto-Germanic did possess. However, this way of comparing Balto-Finnic and Germanic is flawed in an important respect: what we are doing is assessing convergence by comparing the dynamic development from Finno-Saamic to Balto-Finnic to the static system of Proto-Germanic, as if Proto-Germanic is not itself the result of a set of changes to the ancestral Pre-Germanic consonantal system. If we wish to find out whether there was convergence and which language converged on which, what we should do, therefore, is to compare the dynamic development of Finno-Saamic to Balto-Finnic to the dynamic development of Pre-Germanic to Proto-Germanic, because only that procedure will allow us to state whether Balto-Finnic moved towards Proto-Germanic, or Proto-Germanic moved towards Balto-Finnic, or both moved towards a third language. The Pre-Germanic consonantal system can be reconstructed as follows: 7

pre-germanic-proto-germanic-verner-s-law

The slashes in the second and third rows indicate the uncertainty about the Proto-Indo-European nature of the sounds involved. (…)

What resulted was the following Proto-Germanic consonant system:

proto-germanic-consonant-system

We are now in a better position to answer the question whether Proto-Germanic and Balto-Finnic have converged. Three striking developments affected both languages:

  • Both languages lost the palatalized series of consonants (apart from j), which in both languages became non-palatalized.
  • Both languages developed an extensive set of long (geminate) consonants; Pre-Germanic had none, while Finno-Saamic already had a few.
  • Both languages developed an h.

These similarities between the languages are considerable.

The idea that perhaps both languages moved towards a lost third language, whose speakers may have been assimilated to both Balto-Finnic and Germanic, provides a fuller explanation but suffers from the drawback that it shifts the full burden of the explanation to a mysterious ‘language X’ that is called upon only in order to explain the developments in Proto-Germanic and Balto-Finnic. That comes dangerously close to circular reasoning.

Verner’s Law in Pre-Germanic

As we have seen in the preceding section, Verner’s law is a sound change that affected originally voiceless consonants, so *p , t , k , kj , kw, s of the Pre-Germanic system. These normally became the Proto-Germanic voiceless fricatives *f, θ, h, h, hw, s, respectively. But if *p, t, k etc. were preceded by an originally unstressed syllable, Verner’s law intervened and they were turned into voiced consonants. Those voiced consonants merged with the series *bh, dh, gh of the Pre-Germanic system and therefore subsequently underwent all changes that the latter did, turning out as *b/v , *d/ð , g/γ in the Proto-Germanic system (that is, v, ð, γ after a vowel and b, d, g in all other environments in the word). When *s was affected by Verner’s Law, a new phoneme *z arose. In a diagram:

pre-germanic-verner-s-law

While it is very common in the history of European languages for stress to influence the development of vowels, it only very rarely affected consonants in this part of the world. Verner’s law is a striking exception. It resembles a development which, on a much larger scale, affected Finno-Saamic: consonant gradation.(…)

In all Finno-Saamic languages, rhythmic gradation has become phonemic and fossilized. The connection between rhythmic gradation and Verner’s law is relatively straightforward: both processes involve changing a voiceless consonant after an unstressed syllable. (…)

We can therefore repeat for Proto-Uralic the argument that persuaded us earlier that gradation in Saami and Balto-Finnic must go back to the common Finno-Saamic protolanguage: the similarity of the gradation rules in Nganasan to those in Finno-Saamic is so specific and so detailed, and the phenomenon of gradation so rare in the languages of the world, that gradation must be reconstructed for the Uralic protolanguage.

Verner’s law turns all voiceless obstruents (Pre-Germanic *p, t, k, kj, kw, s) into voiced obstruents (ultimately Proto-Germanic *b/v , d/ð, g/γ, g/γ, gw, z) after a Pre-Germanic unstressed syllable. Rhythmic gradation turns all voiceless obstruents after an unstressed syllable into weak-grade consonants, which means that *p, t, k, s become Finnic *b/v , d/ð , g/γ, z. This is striking. Given the geographical proximity of Balto-Finnic and Germanic and given the rare occurrence of stress-related consonant changes in European languages, it would be unreasonable to think that Verner’s law and rhythmic gradation have nothing to do with one another.

It is very hard to accept, however, that gradation is the result of copying Verner’s law into Finnic. First of all, Verner’s law, which might account for rhythmic gradation, in no way accounts for syllabic gradation in Finnic. And, second, gradation can be shown to be an inherited feature of Finnic which goes all the way back to Proto-Uralic. Once one acknowledges that Verner’s law and gradation are causally linked and that gradation cannot be explained as a result of copying Verner’s law into Finnic, there remains only one possibility: Verner’s law is a copy of Finnic rhythmic gradation into Germanic. That means that we have finally managed to find what we were looking for all along: a Finnic sound feature in Germanic that betrays that Finnic speakers shifted to Germanic and spoke Germanic with a Finnic accent. The consequence of this idea is dramatic: since Verner’s law affected all of Germanic, all of Germanic has a Finnic accent.

indo-european-uralic-bell-beaker-corded-ware-migrations
Late Chalcolithic migrations ca. 2600-2250 BC.

On the basis of this evidence for Finnic speakers shifting to Germanic, it is possible to ascribe other, less specifically Finnic traits in Germanic to the same source. The most obvious trait is the fixation of the main stress on the initial syllable of the word. Initial stress is inherited in Finno-Saamic but was adopted in Germanic only after the operation of Verner’s law, quite probably under Finnic influence. The consonantal changes described in section V.3.1 can be attributed to Finnic with less confidence. The best case can be made for the development of geminate (double) consonants in Germanic, which did not inherit any of them, while Finno-Saamic inherited *pp, tt, kk, cc and took their presence as a cue to develop other geminates such as *nn and *ll . Possibly geminates developed so easily in Proto-Germanic because Finnic speakers (who switched to Germanic) were familiar with them. Other consonantal changes, such as the loss of the palatalized series in both Germanic and Balto-Finnic and the elimination of the different s- and c-phonemes, might have occurred for the same reason: if Balto-Finnic had undergone them earlier than Germanic, which we do not know, they could have constituted part of the Balto-Finnic accent in Germanic. An alternative take on those changes starts from the observation that they all constitute simplifications of an older, richer system of consonants. While simplifications can be and often are caused by language shift if the new speakers lacked certain phonemes in their original language, simplifications do not require an explanation by shift: languages are capable of simplifying a complex system all by themselves. Yet the similarities between the simplifications in Germanic and in Balto-Finnic are so obvious that one would not want to ascribe their co-occurrence to accidental circumstances.

Grimm’s Law in Proto-Germanic (speculative)

Voiceless lenis pronunciation of b, d, g is typical of the majority of German and Scandinavian dialects, so may well have been inherited from Proto-Germanic. Voiceless lenis is also the pronunciation that has been assumed to underlie the weak grades of Finno-Saamic single *p, t, k. If Proto-Germanic *b, d, g were indeed voiceless lenis, the single most striking result of the Germanic consonant shift is that it eliminated the phonological difference between voiced and voiceless consonants that Germanic had inherited from Proto-Indo-European (…) Since neither Finno-Saamic nor Balto-Finnic possessed a phonological difference between voiced and voiceless obstruents, its loss in Proto-Germanic can be regarded as yet another example of a Finnic feature in Germanic.

grimms-law

It is clear that this account of the first Germanic consonant shift as yet another example of Finnic influence is to some degree speculative. The point I am making is not that the Germanic consonant shift must be explained on the basis of Finnic influence, like Verner’s law and word-initial stress, only that it can be explained in this way, just like other features of the Germanic sound system discussed earlier, such as the loss of palatalized consonants and the rise of geminates.

A consequence of this account of the origins of the Proto-Germanic consonantal system is that the transition from Pre-Germanic to Proto-Germanic was entirely directed by Finnic. Or, to put it in less subtle words: Indo-European consonants became Germanic consonants when they were pronounced by Finnic speakers.

post-bell-beaker-europe
Post-Bell-Beaker Europe, after ca. 2200 BC.

The vocalic system, on the other hand, presented less difficulties for both, Indo-European and Uralic speakers, since it was quite similar.

Schrijver goes on to postulate certain asymmetric differences in loans, especially with regard to Proto-Germanic, Balto-Finnic, Proto-Saamic, Proto-Baltic, and later contacts, including a potential non-Uralic, non-IE substrate language to justify some of these, which may in turn be connected with Kroonen’s agricultural substrate hypothesis of Proto-Germanic, and thus also with the other surviving Scandinavian Neolithic cultures before the eventual simplification of the cultural landscape during the Bronze Age.

Conclusion on the origin of Germanic

The Finnic-Germanic contact situation has turned out to be of a canonical type. To Finnic speakers, people who spoke prehistoric Germanic and its ancestor, Pre-Germanic, must have been role models. Why they were remains unclear. In the best traditions of Uralic–Indo-European contacts, Finnic speakers adopted masses of loanwords from (Pre-)Germanic. Some Finnic speakers even went a crucial step further and became bilingual: they spoke Pre-Germanic according to the possibilities offered by the Finnic sound system, which meant they spoke with a strong accent. The accent expressed itself as radical changes in the Pre-Germanic consonantal system and no changes in the Pre-Germanic vowel system. This speech variety became very successful and turned an Indo-European dialect into what we now know as Germanic. Bilingual speakers became monolingual speakers of Germanic.

What we do not know is for how long Finnic-Germanic bilingualism persisted. It is possible that it lasted for some time because both partners grew more alike even with respect to features whose origin we cannot assign to either of them (loss of palatalized consonants): this suggests, perhaps, that both languages became more similar because generally they were housed in the same brain. What we can say with more confidence is that the bilingual situation ultimately favoured Germanic over Finnic: loanwords continued to flow in one direction only, from Germanic to Finnic, hence it is clear that Germanic speakers remained role models.

This is as far as the linguistic evidence can take us for the moment.

Based on archaeology and genetics, I think we can say that the close North-West Indo-European – Proto-Finnic interaction in Scandinavia lasted for hundreds of years, during the time when a unifying Nordic culture and language developed from Bell Beaker maritime elites dominating over Corded Ware groups.

As we know, Uralic languages were in close contact with Middle PIE, and also later with Proto-Indo-Iranian. This Pre-Germanic development in Scandinavia is therefore another hint at the identification of a rather early Proto-Finnic spoken in the Baltic area – potentially then by Battle Axe groups – , and thus the general identification of Uralic expansion with the different Corded Ware groups.

NOTE. The ‘common’ loss of certain palatals, which Schrijver interprets as a change of Pre-Germanic from the inherited Proto-Indo-European, may in fact not be such – in the opinion of bitectalists, including us, and especially taking the North-West Indo-European reconstruction and the Corded Ware substrate hypothesis into account – , so this effect would be a rather unidirectional shift from Finnic to Germanic. On the other hand, certain palatalization trends which some have described for Germanic could in fact be explained precisely by this bidirectional influence.

The future of the Reich Lab’s studies and interpretations of Late Indo-European migrations

yamna-corded-ware-bell-beaker-reich

Short report on advances in Genomics, and on the Reich Lab:

Some interesting details:

  • The Lab is impressive. I would never dream of having something like this at our university. I am really jealous of that working environment.
  • They are currently working on population transformations in Italy; I hope we can have at last Italic and Etruscan samples.
  • It is always worth it to repeat that we are all the source of multiple admixture events, many of them quite recent; and I liked the Star Wars simile.
  • Also, some names hinting at potential new samples?? Zajo-I, Chanchan, Gurulde?, Володарка (Ukraine – medieval?), Autodrom, Облевка, Кресты, Кудуксай (Ural region, palaeo-metal?), Золкут, etc.

On the bad aspect, they keep repeating the same “steppe ancestry” meme (in the featured image above, or the one below). I know this is the news report (i.e. science communication), not exactly the Reich Lab, but these maps didn’t appear out of the blue.

Interesting for future interpretations is the whiteboard behind David Reich’s back (apparently they like to keep relevant information on whiteboards…):

It seems that while the Copenhagen group will still be bound (see here) by the Gimbutas/Kristiansen starting point, the Reich Lab will remain bound by Anthony’s selection of Ringe’s (2002) glottochronological model, and they will try to make genomic data fit in with it.

In fact, the whiteboard doesn’t even include Ringe’s link of Germanic with Italo-Celtic, which could maybe hint at Anthony’s recent change of heart? (i.e. Yamna Hungary -> Corded Ware). That would mean still less Linguistics (if glottochronology can be called that), and more Archaeology…

I don’t know why university labs need to do this: To select the linguistic model preferred by a single archaeologist, which happens to be the lead archaeologist of the group, and then try to make genetic data agree again and again with that model. I guess it is a strategic question, and has to do with granting continued contacts with archaeological sites, and access to samples from them?

I understand none of them will try to learn ancient languages, too much work probably. But, wouldn’t it have been more scientifish, at least, to depart from, say, three or four reasonable potential linguistic models (that is, from Indo-Europeanists), and from there discuss the best potential fits for the current genomic data in each paper?

This is, for example, how the Heyd (archaeologist) + German/Spanish Indo-Europeanist schools would look like:

yamnaya-heyd-dunkel
Yamnaya expansion coupled with Meid’s (1975) description of three stages of Proto-Indo-European development (as interpreted by Adrados 1998) and depiction of Heyd’s proposal of Yamna expansion.

Wouldn’t you say it could have fitted the statistical and Y-DNA data seamlessly, in contrast to Gimbutas/Trager (i.e. Kristiansen today), or to Anthony/Ringe?

NOTE. I would say the mainstream German school follows Meid’s (1975) three-stage theory coupled with Dunkel’s (e.g. 1997) nomenclature. The Spanish school follows Adrados, who has repeated ad nauseam that he was the first to mention the three-stage theory in conferences and papers previous to and coincident with Meid’s proposal (see his latest JIES article, a paper available in Scribd). In any case, Spanish and German scholars have been working hand in hand in accepting and developing a general linguistic model similar to the one above.

Archaeological theories like those of Heyd or Mallory for Yamna and Bell Beaker (in contrast to Kristiansen or Anthony), and Prescott and Walderhaug for Bell Beaker and Germanic (contrasting with Kristiansen and Iversen) are compatible with this German/Spanish model.

The French school is non-existent on the homeland matter, Italian scholars seem to be behind even in the description of Anatolian as archaic (probably related to the general wish to have Latin as derived from Vergil’s Troy), Russian scholars are still working with Nostratic and Mesolithic expansions, and Leiden, as the leading IE publisher worldwide today, is full of very different ‘divos’, each with his own pet theory (some obviously agreeing with the German/Spanish model; and especially interesting is that some of them are strong supporters of an Indo-Uralic proto-language).

The English-speaking world, on the other hand, has seen the most varied models being either proposed or translated into its language, with the most popular ones being those publicized by archaeologists (Winfred P. Lehmann being one of the noteworthy exceptions), which may explain why for some people (archaeologists or geneticists) linguistics seems more like a game. It is to be assumed that these same people haven’t taken a look at the dozens of genetic papers published to date – and hundreds of archaeological papers using a bit of linguistics to support their models – , and how wrong they have all been in their interpretations, or else they would realize that genomics does (sadly) not really look like a serious discipline at all right now among most linguists, and among many archaeologists either…

Thus, instead of comparing the main theories on Proto-Indo-European (i.e. linguistics->archaeology->genetics), which would have offered the most stable framework to assess potential prehistoric ethnolinguistic identifications, they keep using a single, simplistic language tree liked by an archaeologist, and trying to fit genetic data to it, while also adapting archaeology to genetics, i.e. genetics->archaeology->linguistics; which, as you can imagine, is not going to convince any linguist.

Especially disappointing is that the world’s leading genetic lab still relies on a marginal proposal based on glottochronology, the homeopathy of linguistics… At least in that regard everyone should know better by now.

Also, they keep interacting with the wrong audience: instead of trying to engage linguists into the real homeland and dialectal quest, to keep Genomics a serious discipline among academics, they tend to discuss with politically- or racially-motivated people, which is probably also in line with strategic decisions.

In the example below, we see the main author of their recent paper on Indo-Iranian migrations seeking once again interaction, this time through “news” promoted by Hindu nationalist bigots, so that – even if that makes them look more neutral in the eyes of those who may allow access to Indian samples – , in the end, we see in genomics a fictitious revival of the “AIT vs. OIT debate” dead long ago in linguistics and archaeology (anywhere but in India).

Pretty disappointing to see these trends; so much effort and time invested in futile discussions and infinitely reworked doomed glottochronological or 19th-century models, when it is the fine-scale population structure of expanding Yamna peoples what we should be discussing now, and thus Late PIE dialectalisation with offshoots Afanasevo, East Bell Beaker, Balkan Bronze Age, and Sintashta/Potapovka; as well as Corded Ware evolution in Uralic-speaking territory.

Minimal Corded Ware culture impact in Scandinavia – Bell Beakers the unifying maritime elite

copper-age-late-bell-beaker

Chapter The Sea and Bronze Age Transformations, by Christopher Prescott, Anette Sand-Eriksen, and Knut Ivar Austvoll, In: Water and Power in Past Societies (2018), Emily Holt, Proceedings of the IEMA Postdoctoral Visiting Scholar Conference on Theories and Methods in Archaeology, Vol. 6.

Abstract (emphasis mine):

Along the western Norwegian coast, in the northwestern region of the Nordic Late Neolithic and Bronze Age (2350–500 BCE) there is cultural homogeneity but variable expressions of political hierarchy. Although new ideological institutions, technology (e.g., metallurgy and boat building), intensified agro‑pastoral farming, and maritime travel were introduced throughout the region as of 2350 BCE, concentrations of expressions of Bronze Age elites are intermittently found along the coast. Four regions—Lista, Jæren, Karmøy, and Sunnmøre—are examined in an exploration of the establishment and early role of maritime practices in this Nordic region. It is argued that the expressions of power and material wealth concentrated in these four regions is based on the control of bottlenecks, channels, portages, and harbors along important maritime routes of travel. As such, this article is a study of prehistoric travel, sources of power, and maritime landscapes in the Late Neolithic and Early Bronze Age of Norway.

Interesting excerpts:

(…)The [Corded Ware culture (CWC)] in Norway (or Battle Axe Culture, 2750–2400/2350 BCE) is primarily represented in Eastern Norway, with a patchy settlement pattern along the Oslo fjord’s coast through the inland valleys to Trøndelag in Central Norway (Hinsch 1956). The CWC represents an enigmatic period in Norwegian prehistory (Hinsch 1956; Østmo 1988:227–231; Prescott and Walderhaug 1995; Shetelig 1936); however the data at the moment suggests the following patterns:

  • Migration: The CWC was the result of a small‑scale immigration, but did not trigger substantial change.
  • Eastern and limited impact: The CWC was primarily located in small settlement patches in eastern Norway.
  • Terrestrial: In terms of maritime practices, the CWC does not represent a significant break from older traditions, though it seems to have a more pronounced terrestrial bearing. It is conceivable that pastures and hunting grounds were a more important political‑economic resource than waterways.

The mid‑third millennium in Norway, around 2400 BCE, represents a significant reorientation. Bell Beaker Culture (BBC) settlements in western Denmark and Norway archaeologically mark the instigation of the Nordic LN, though much of the historical process leading from the Bell Beaker to the Late Neolithic, 2500 to 2350 BCE, remains unclear (Prescott 2012; Prescott and Melheim 2009; Prieto‑Martinez 2008:116; Sarauw 2007:66; Vandkilde 2001, 2005). Still, the outcome is the establishment of the Nordic region of interaction in the Baltic, Northern Germany, Sweden, Denmark, and Norway. The distribution of artifact materials such as Bell Beakers and flint daggers attests to the far‑flung network of regular exchange and communication. This general region of interaction was reproduced through the Late Neolithic and Bronze Age.

The transition from the preceding Neolithic period hunter‑gatherer societies was rapid and represents a dramatic termination of hunter‑gatherer traditions. It has been argued that the transformation is tied to initial migrations of people to the western coast of Norway from BBC areas, possibly from northern Jutland (Prescott 2011; Prescott and Walderhaug 1995:273). Bifacial tanged‑and‑barbed points, often referred to as “Bell Beaker points,” probably represent an early, short phase of the BBC‑transition around 2400 BCE. In Norway these points have a predominantly western and coastal distribution (Østmo 2012:64), underscoring the maritime nature of the initial BBC‑expansion.

(…) In response to the question about what attracted people from Bell Beaker groups to western Norway, responses have hypothesized hunting products, political power, pastures, and metals. Particularly the latter has been emphasized by Lene Melheim (2012, 2015:37ff).

A recent study by Melheim and Prescott (2016) integrated maritime exploration with metal prospecting to explain initial excursions of BBC‑people along the western coast and into the fjords. Building on the archaeological concept of traveling metal prospectors as an element in the expansion of the Bell Beaker phenomenon, in combination with anthropological perspectives on prospecting, the article explores how prospecting for metal would have adjusted to the landscapes of western Scandinavia. Generally speaking, prospecting seldom leads to successful metal production, and it is difficult to study archaeologically. However, it will often create links between the prospectors’ society and indigenous groups, opening new territories, and have a significant transformative impact—on both the external and indigenous actors and societies.

While the text echoes the traditional idea that Corded Ware spread Indo-European languages, Prescott (since Prescott and Walderhaug 1995) is a supporter of the formation of a Nordic community and a Nordic (i.e. Pre-Germanic) language with the arrival of Bell Beakers.

An identification of the Corded Ware language as of a previous Proto-Indo-European stage is possible, as I have previously said (although my preference is Uralic-related languages).

This CWC language would thus still form the common substrate to both Germanic and Balto-Slavic, both being North-West Indo-European dialects, which spread with Bell Beakers over previous Corded Ware territory.

NOTE. This pre-LPIE nature could be in turn related to Kortlandt’s controversial proposal of an ealier PIE dative *-mus shared by both branches. However, that would paradoxically be against Kortlandt’s own assumption that the substrate was in fact of a non-Indo-European nature

Reproductive success among ancient Icelanders stratified by ancestry

iceland-pca

New paper (behind paywall), Ancient genomes from Iceland reveal the making of a human population, by Ebenesersdóttir et al. Science (2018) 360(6392):1028-1032.

Abstract and relevant excerpts (emphasis mine):

Opportunities to directly study the founding of a human population and its subsequent evolutionary history are rare. Using genome sequence data from 27 ancient Icelanders, we demonstrate that they are a combination of Norse, Gaelic, and admixed individuals. We further show that these ancient Icelanders are markedly more similar to their source populations in Scandinavia and the British-Irish Isles than to contemporary Icelanders, who have been shaped by 1100 years of extensive genetic drift. Finally, we report evidence of unequal contributions from the ancient founders to the contemporary Icelandic gene pool. These results provide detailed insights into the making of a human population that has proven extraordinarily useful for the discovery of genotype-phenotype associations.

icelanders
Shared drift of ancient and contemporary Icelanders. (A) Scatterplot of D-statistics reflecting Iceland-specific drift. To aid interpretation, we included values for ancient British-Irish Islanders and a subset of contemporary individuals (who were correspondingly removed from the reference populations).

We estimated the mean Norse ancestry of the settlement population (24 pre-Christians and one early Christian) as 0.566 [95% confidence interval (CI) 0.431–0.702], with a nonsignificant difference betweenmales (0.579) and females (0.521). Applying the same ADMIXTURE analysis to each of the 916 contemporary Icelanders, we obtained a mean Norse ancestry of 0.704 (95% CI 0.699–0.709). Although not statistically significant (t test p = 0.058), this difference is suggestive. A similar difference ofNorse ancestry was observed with a frequency-based weighted least-squares admixture estimator (16), 0.625 [Mean squared error (MSE) = 0.083] versus 0.74 (MSE = 0.0037). Finally, the D-statistic test D(YRI, X; Gaelic, Norse) also revealed a greater affinity between Norse and contemporary Icelanders (0.0004, 95% CI 0.00008–0.00072) than between Norse and ancient Icelanders (−0.0002, 95% CI −0.00056–0.00015). This observation raises the possibility that reproductive success among the earliest Icelanders was stratified by ancestry, as genetic drift alone is unlikely to systematically alter ancestry at thousands of independent loci (fig. S10). We note that many settlers of Gaelic ancestry came to Iceland as slaves, whose survival and freedom to reproduce is likely to have been constrained (17). Some shift in ancestry must also be due to later immigration from Denmark, which maintained colonial control over Iceland from 1380 to 1944 (for example, in 1930 there were 745 Danes out of a total population of 108,629 in Iceland) (18).

icelander-admixture
Shared drift of ancient and contemporary Icelanders. (B) Estimated Norse,
Gaelic, and Icelandic ancestry for ancient Icelanders using ADMIXTURE
in supervised mode.

Five pre-Christian Icelanders (VDP-A5, DAVA9, NNM-A1, SVK-A1 and TGS-A1) fall just outside the space occupied by contemporary Norse in Fig. 3A. That these individuals show a stronger signal of drift shared with contemporary Icelanders is also apparent in the results of ADMIXTURE, run in supervised mode with three contemporary reference populations (Norse, Gaelic, and Icelandic) (Fig. 3B). The correlation between the proportion of Icelandic ancestry from this analysis and PC1 in Fig. 2A is |r| = 0.913.(…)

(…) as the five ancient Icelanders fall well within the cluster of contemporary Scandinavians (Fig. 3C), we conclude that they, or close relatives, likely contributed more to the contemporary Icelandic gene pool than the other pre-Christians. We note that this observation is consistent with the inference that settlers of Norse ancestry had greater reproductive success than those of Gaelic ancestry.

icelanders-y-dna
Haplogroup data, from the paper. Image modified by me, with those close to Gaelic and British/Irish samples (see above Scatterplot of D-statistics and ADMIXTURE data) marked in fluorescent: yellow closer to Gaelic, green less close.

Ancient Icelanders show a clear relation with the typically Norse Y-DNA distribution: I1 / R1a-Z284 / R1b-U106.

  • Among R1a, the picture is uniformly of R1a-Z284 (at least five of the seven reported).
  • There are six samples of I1, with great variation in subclades.
  • Among R1b-L51 subclades (ten samples), there are U106 (at least one sample), L21 (three samples), and another P312 (L238); see above the relationship with those clustering closely with Gaelic samples, marked in fluorescent, which is compatible with Gaelic settlers (predominantly of R1b-L21 lineages) coming to Iceland as slaves.

Probably not much of a surprise, coming from Norse speakers, but they are another relevant reference for comparison with samples of East Germanic tribes, when they appear.

Also, the first reported Klinefelter (XXY) in ancient DNA (sample ID is YGS-B2).

Copenhagen group: Germanic and Balto-Slavic from Bell Beaker; Indo-Anatolian homeland in the Caucasus

invasion-from-the-steppe-yamnaya

Article of general knowledge in Der Spiegel, Invasion from the Steppe, with comments from Willerslev and Kristiansen, appeared roughly at the same time as the Damgaard et al. Nature (2018) and Science (2018) papers were published.

NOTE. You can read the article (in German) from Kristiansen’s Academia.edu account.

Excerpts translated from German (emphasis mine):

On the Y-DNA data

Particularly striking is the genetic signature from the steppe on the Y chromosome. From this the researchers conclude that the majority of migrants were males. Kristian Kristiansen, chief archaeologist in the Willerslev team, also has an idea of ​​how this could be explained: “Maybe it’s a rite of initiation, as it was spread among the steppe peoples,” he says.

The younger sons of the Yamnaya herders, who were excluded from the succession, had to seek their fortune on their own. As part of a solemn ritual, they threw themselves to wolves’ skins and then swarmed in warlike gangs to buy their own herds by cattle-stealing.

(…)

An ally that they seem to have brought from their homeland may also have contributed to the genetic success of the steppe people: Yersinia pestis, the plague bacterium. Its genes were found by researchers from the Max Planck Institute in Jena – and apparently it emerged exactly at the same time as the Yamnaya thrust began.

About the Hittites

(…) And yet now, where Asia and Europe meet geographically, there is no trace of the Yamnaya genes. The wander-loving people from the Pontic-Caspian steppe apparently found neither the way across the Balkans nor through the Caucasus mountains.

Now the researchers are puzzled: How can it be that a language goes on a walk, without the accompanying speakers coming along? Is it possible that the Indo-European seeped into Anatolia, much like the English language spread today without the need for Englishmen?

Archaeologist Kristiansen does not believe it. The researchers would find it hard to reconsider their theories, he says: “Especially the first chapter of the story has to be rewritten.”

He suspects that there was a predecessor of the Yamnaya culture, in which a kind of Proto-Proto-Indo-European was spoken. And he also has a suspicion, where this people could have drifted around: The Caucasus, says Kristiansen, was their homeland. But that remains unproven: “There’s another hole left,” he admits.

Spread of Indo-European languages

About the Botai

The study of [the Botai] genome revealed that it was genetically radically different from the members of the Yamnaya culture. The Botai, it seems, consistently avoided any contact with their neighbors – even though they must have crossed the territory of the Botai on their migratory waves.

Willerslev assumes that the art of keeping horses from the Yamnaya steppe nomads was adopted from these peoples, and then they developed it further. At some point, the Botai could then have itself become doomed by its groundbreaking innovation: While the descendants of the Yamnaya spread over half of Eurasia, the Botai disappeared without leaving a trace.

Even more interesting than the few words that set the Copenhagen group’s views for future papers (such as the expected Maykop samples with EHG ancestry) is the artistic sketch of the Indo-European migrations, probably advised by the group.

A simple map does not mean that all members of the Danish workgroup have changed their view completely, but I would say it is a great improvement over the previous “arrows of migration” (see here), and it is especially important that they show a more realistic picture of ancient migrations to general readers.

NOTE. Especially absurd is the identification of the ‘Celtic’ expansion with the first Bell Beakers in the British Isles (that idea is hold by few, such as Koch and Cunliffe in their “Celtic from the West” series). Also inexact, but not so worrying, are the identification of ‘Germanic’ in Germany/Únětice, or the spread of ‘Baltic’ and ‘Slavic’ directly to East Europe (i.e. I guess Mierzanowice/Nitra -> Trzciniec), which is probably driven by the need to assert a close connection with early Iranians and thus with their satemization trends.

Also, as we know now thanks to Narasimhan et al. (2018), there is no need to support that convoluted west arrow (representing CWC) from West Yamna to Central Europe, and then to East Yamna, since the Proto-Indo-Iranian community – represented by the Steppe MLBA cloud that later expanded Indo-Aryan and Iranian languages – has a more direct connection with the in situ admixture of Poltavka/Abashevo within the Volga-Ural region.

I think we can keep this from the article:

Their results, as well as those of the competition labs at Harvard University and Jena’s Max Planck Institute for the History of Humanity, leave no doubt: Yes, the legendary herdsmen in the Pontic-Caspian steppe really existed. They belonged to the so-called Yamnaya culture, and they spread, as linguists had predicted, in massive migrations towards Central Europe and India – a later triumph for linguists.

This can be added to a recent comment by de Barros Damgaard:

The project has been an extremely enriching and exciting process. We were able to direct many very different academic fields towards a single coherent approach. By asking the right questions, and keeping limitations of the data in mind, contextualizing, nuancing, and keeping dialogues open between scholars of radically different backgrounds and approaches, we have carved out a path for a new field of research. We have already seen too many papers come out in which models produced by geneticists working on their own have been accepted without vital input from other fields, and, at the other extreme, seen archaeologists opposing new studies built on archaeogenetic data, due to a lack of transparency between the fields.

Data on ancient DNA is astonishing for its ability to provide a fine-grained image of early human mobility, but it does stand on the shoulders of decades of work by scholars in other fields, from the time of excavation of human skeletons to interpreting the cultural, linguistic origins of the samples. This is how cold statistics are turned into history.

Consequences of Damgaard et al. 2018 (III): Proto-Finno-Ugric & Proto-Indo-Iranian in the North Caspian region

copper-age-early_yamna-corded-ware

The Indo-Iranian – Finno-Ugric connection

On the linguistic aspect, this is what the Copenhagen group had to say (in the linguistic supplement) based on Kuz’mina (2001):

(…) a northern connection is suggested by contacts between the Indo-Iranian and the Finno-Ugric languages. Speakers of the Finno-Ugric family, whose antecedent is commonly sought in the vicinity of the Ural Mountains, followed an east-to-west trajectory through the forest zone north and directly adjacent to the steppes, producing languages across to the Baltic Sea. In the languages that split off along this trajectory, loanwords from various stages in the development of the Indo-Iranian languages can be distinguished: 1) Pre-Proto-Indo-Iranian (Proto-Finno-Ugric *kekrä (cycle), *kesträ (spindle), and *-teksä (ten) are borrowed from early preforms of Sanskrit cakrá- (wheel, cycle), cattra- (spindle), and daśa- (10); Koivulehto 2001), 2) Proto-Indo-Iranian (Proto-Finno-Ugric *śata (one hundred) is borrowed from a form close to Sanskrit śatám (one hundred), 3) Pre-Proto-Indo-Aryan (Proto-Finno-Ugric *ora (awl), *reśmä (rope), and *ant- (young grass) are borrowed from preforms of Sanskrit ā́rā- (awl), raśmí- (rein), and ándhas- (grass); Koivulehto 2001: 250; Lubotsky 2001: 308), and 4) loanwords from later stages of Iranian (Koivulehto 2001; Korenchy 1972). The period of prehistoric language contact with Finno-Ugric thus covers the entire evolution of Pre-Proto-Indo-Iranian into Proto-Indo-Iranian, as well as the dissolution of the latter into Proto-Indo- Aryan and Proto-Iranian. As such, it situates the prehistoric location of the Indo-Iranian branch around the southern Urals (Kuz’mina 2001).

NOTE. While I agree with the evident ancestral nature of the *kekrä borrowing, I will repeat it here again: I don’t believe that the distinction of late Proto-Indo-Iranian from ‘Pre-Proto-Indo-Aryan’ loans is warranted; not for words reconstructed from recent Finno-Ugric languages.

copper-age-late-urals
The time and place for Finno-Ugric and Indo-Iranian contacts. Late Copper Age migrations in Asia ca. 2800-2300 BC.

In this period of a Pre-Proto-Indo-Iranian community, which is to be associated with East Yamna/Poltavka, ca. 3000-2400 BC – as accepted in the supplement from de Barros Damgaard et al. (Nature 2018) – , both Poltavka and Abashevo/Balanovo herders were expanding ca. 2800-2600 BC to the east (and Abashevo already admixing into Poltavka territory), near the southern Urals.

There is no other, clearer, later connection between Finno-Ugric and Proto-Indo-Iranian speakers. Even the arrival of the Seima-Turbino phenomenon (after ca. 2000 BC), if it brought migrants to North-East Europe, would not fit the linguistic, archaeological, or genetic data. It is by now quite clear that Seima-Turbino does not fit with incoming N1c1 lineages and/or Siberian ancestry, either, for those looking for these as potential signs of incoming Uralic speakers.

While the Copenhagen group did not have access to data from Sintashta ca. 2100 BC onwards – now available in Narasimhan et al. (2018) – when submitting the papers, we already know that there was a clear long period of slow progressive admixture in the North Caspian region. It can be seen in the genetic contribution of Yamna to incoming Abashevo groups, and in the R1b-L23 samples still appearing in Sintashta until ca. 1800 BC (as I predicted could happen).

Since the first sample signalling incoming Abashevo migrants is found in the Poltavka outlier dated ca. 2700 BC (of R1a-Z93 lineage), this represents a rather unique, several centuries long process of admixture in the North Caspian region, different from the massive Afanasevo or Bell Beaker migrations in Asia and Europe, whereby a great part of the native male population was suddenly replaced.

This offers further support for language continuity despite genetic replacement in the development of East Yamna/Poltavka (part of the Steppe EMBA cline, formed by Yamna and Afanasevo) mixing with Abashevo migrants (probably identical to Corded Ware samples) to form Potapovka, Sintashta, and later Srubna, and Andronovo communities (all forming, with Corded Ware groups, a wide Eurasian Steppe MLBA cloud). See the available data from Narasimhan et al. (2018).

Original description “Modeling results including Admixture events, with clines or 2-way mixtures shown in rectangles, and clouds or 3-way mixtures shown in ellipses”. See the original full image here.

The continuous interactions and migrations left thus eventually two communities in the southern Urals genetically similar, but ethnolinguistically diverse:

  • To the north, Abashevo-Balanovo – but potentially also Fatyanovo, and related North-East European late Corded Ware groups – borrowed necessary words from Indo-Iranian neighbours, while maintaining their Finno-Ugric language and culture.
  • To the south, immigrants (or their descendants) of Abashevo origin expanding among Pre-Proto-Indo-Iranian-speaking North Caspian communities assimilated the surrounding culture and language, giving it their own accent (i.e. ‘satemizing’ it) and turning it into Proto-Indo-Iranian (see e.g. Parpola’s account).

Anthropologically, this ‘long-term founder effect’ that appears as genetic replacement is probably explained by the faster life history in MLBA North Caspian populations, likely due to a combination of changing environmental and social circumstances.

NOTE. The prevalent explanation before the latest studies on the Sintashta society were social strife and isolation of small groups, an argument I used in my demic diffusion model. Other, similar cases of proven linguistic continuity despite genetic replacement are seen in Iberian Bronze Age after the expansion of R1b-L23 lineages (with Vasconic, Iberian, and Tartessian surviving at least until proto-historic times), and in Remote Oceania.

Implications for Late PIE migrations

I am happy to see that people are resorting now to dialectal classifications and Y-DNA to explain the findings in Old Hittites, Tocharians (and related migrations), and Indo-Iranians. It is especially interesting to see precisely this Danish group downplay the relevance of ancestry and favor complex anthropological models when assessing migrations and ethnolinguistic identification.

So let’s talk about the growing elephant in the room.

It seems we all accept now Tocharian’s more archaic Late PIE nature, which is supported by waves of late Khvalynsk migrants starting probably ca. 3300 BC, as seen in different samples to the east in Central Asia, and to the south in Iran. Almost all of them share R1b-L23 lineages.

NOTE. Whereas their early LPIE dialects have not survived to historic times, the rather speculative hypotheses of Euphratic and Gutian languages may be of interest.

We also know of the coetaneous migrants that settled to the west of the Don River (in the territory of the previous late Sredni Stog culture), to form the western South-Bug / Lower Don groups, which, together with the Volga-Ural / North Caucasian groups formed the early Yamna culture, that dominated from ca. 3300 BC over the Pontic-Caspian steppe.

It is only logical that the other attested languages belonging to the common Late PIE trunk must come from these groups, which must have stuck together for quite some time – after the recently proven late Khvalynsk migrations – , to allow for the spread of isoglosses (not found in Tocharian) among them.

This is agreed, even by the Copenhagen group, who expressly state that Yamna is to be identified with the rest of Late PIE languages after the Tocharian-related migrations.

copper-age-early_yamna-corded-ware
Early Yamna community and its migrations ca. 3000 BC onwards.

The period of an early Yamna community constrained to the Pontic-Caspian steppe (ca. 3300-3000 BC) is followed by renewed waves of Late Proto-Indo-European migrations, during which areal contacts and innovations (even between unrelated LPIE branches) can still be reconstructed.

These later migrations can be precisely described as follows (after the latest studies):

  • Yamna migrants, of mixed R1b-L51 and R1b-Z2103 lineages, settle ca. 3000-2600 BC along the lower Danube, in the Balkans and the Carpathian basin, giving rise later to groups of:
  • In the Pontic-Caspian steppe, early Yamna groups evolve into (from west to east) Late Yamna, Catacomb, and Poltavka groups, ca. 2800-2300 BC, all still dominated by R1b-L23 lineages (see discussion on the Catacomb sample), with:
    • Poltavka peoples admixing with Abashevo migrants to form admixed Potapovka and Sintashta-Petrovka groups, showing still after ca. 1800 BC a mixed society of R1a-Z93 and R1b-Z2103 lineages (see Narasimhan et al. 2018);
      • Expanding early Proto-Iranian and Proto-Indo-Aryan groups in Srubna (to the west) and Andronovo (to the east), during the first half of the 2nd millennium BC, dominate over the Bronze Age steppe and Central Asia with expanding R1a-Z93 lineages.

Conclusion

chalcolithic_late_Europe_Bell_Beaker
Diachronic map of Late Copper Age migrations including Classical Bell Beaker (east group) expansion from central Europe ca. 2600-2250 BC

1) East Bell Beakers clearly dominated culturally and genetically over almost all of Europe, ca. 2500-2000 BC, including previous Corded Ware territory, representing thus the most recent massive migration of steppe peoples in Europe, and being the only pan-European culture derived from Late Proto-Indo-European-speaking Yamna. They must therefore be identified with North-West Indo-European speakers, as proposed by Mallory (2013), and not just Italo-Celtic (as supported recently by the Danish school, based on Gimbutas’ outdated model):

1.A) For Germanic, we already have proof that an appropriate, unitary Scandinavian society, ripe for the development of a common Pre-Germanic language (that expanded much later, during the Iron Age, as Proto-Germanic) could have developed only after the arrival of Bell Beakers (see Prescott 2017). The association of proto-historic Germanic tribes mainly with the expansion of R1b-U106 lineages bears witness to that.

NOTE. Even without taking into account the likely L51 samples from Khvalynsk, it is by now quite clear that R1b-L51 lineages were already admixed in Yamna settlers from the Carpathian Basin, and any subclade of U106, L21, DF27, or U152 can thus be found everywhere in Europe associated with any of those North-West Indo-European migrations. What we are seing later, as in the East Bell Beaker migrants arriving in the British Isles (L21), Iberia (DF27), or the Netherlands/Scandinavia (U106), is the further reduction in variability coupled with the expansion of a few sucessful families (and their lineages), as we know it usually happens during migrations.

1.B) For Balto-Slavic, it seems they were not part of the eastern Corded Ware peoples: the Copenhagen group denies an Indo-Slavonic group in the Nature paper, referring instead to a dominion of early Iranians in the steppes, following their traces to proto-historic and historic Iranian-speaking peoples. And we knew already that Bell Beakers dominated over Central-East Europe, before the resurge of R1a-Z645 lineages in the region, which is compatible with the North-West Indo-European nature of their language undergoing a satemization process similar (but not equal to) to the Indo-Iranian one (see the full discussion on Balto-Slavic here).

NOTE. The few ancestral traits common to Germanic and Balto-Slavic are today considered a common substrate language to both, and not due to close contacts (and still less a common branch, as was proposed in the 1st half of the 20th c.). You can read e.g. Kortlandt’s Baltic, Slavic, Germanic (2017), or our Corded Ware substrate hypothesis (2017). In both theories, the referenced substrate is likely a non-Indo-European language, and in both cases it is related to the Corded Ware culture, which represents their most common immediate ancestral population before the spread of Bell Beakers.

2) The late Corded Ware groups of Finland and Estonia, as well as Fatyanovo and Abashevo (and succeeding groups of Eastern Europe) may now be more clearly associated with Proto-Finno-Ugric dialects, and thus probably Corded Ware groups in general with Uralic languages, whose western branches have not survived to this day, with their culture and language being replaced quite early by expanding Bell Beakers.

NOTE. While the demise of Central and Central-East European CWC groups is evident, continuous contacts among Battle Axe culture groups in Scandinavia and the Gulf of Finland through the Baltic Sea – and the strong Bronze Age Palaeo-Germanic influence on Finnic languages (stronger than earlier Indo-Iranian borrowings) may point to the continuity of Proto-Finnic in Northern Scandinavia, which may force a reinterpretation of the prehistoric location of Proto-Finnic-speaking groups.

Those supporting a Corded Ware expansion of Germanic or Balto-Slavic with R1a subclades, now rejecting the expansion of Proto-Indo-European from an Anatolian homeland (following the spread of Neolithic farmer ancestry), and negating the close Proto-Indo-Iranian – Uralic contacts, are willfully ignoring linguistic, archaeological, and genetic data whenever it does not fit with their previous theories.

Good times ahead to chase false syllogisms and contradictions everywhere.
