Olalde et al. and Mathieson et al. (Nature 2018): R1b-L23 dominates Bell Beaker and Yamna, R1a-M417 resurges in East-Central Europe during the Bronze Age

The official papers Olalde et al. (Nature 2018) and Mathieson et al. (Nature 2018) have appeared. They are based on the 2017 preprints at BioRxiv The Beaker Phenomenon And The Genomic Transformation Of Northwest Europe and The Genomic History Of Southeastern Europe respectively, but with a sizeable number of new samples.

Papers are behind a paywall, but here are the authors’ shareable links to read the papers and supplementary materials: Olalde et al. (2018), Mathieson et al. (2018).

NOTE: The corresponding datasets have been added to the Reich Lab website. Remember you can use my drafts on DIY Human Ancestry analysis (viz. Plink/Eigensoft, PCA, or ADMIXTURE) to investigate the data further in your own computer.

I don’t have time to analyze the samples in detail right now, but in short they seem to convey the same information as before: in Olalde et al. (2018) the pattern of Y-DNA haplogroup and steppe ancestry distribution is overwhelming, with an all-R1b-L23 Bell Beaker people accompanying steppe ancestry into western Europe.

EDIT: In Mathieson et al. (2018), a sample classified as of Ukraine_Eneolithic from Dereivka ca. 2890-2696 BC is of R1b1a1a2a2-Z2103 subclade, so Western Yamna during the migrations also of R1b-L23 subclades, in contrast with the previous R1a lineages in Ukraine. In Olalde et al. (2018), it is clearly stated that of the four BB individuals with higher steppe ancestry, the two with higher coverage could be classified as of R1b-S116/P312 subclades.

This is compatible with the expansion of Indo-European-speaking Yamna migrants (also mainly of R1b-L23 subclades) into the East Bell Beaker group, as described with detail in Archaeology (and with the population movement we are seeing having been predicted) first by Volker Heyd in 2007.

Also, the resurge of R1a-Z645 subclades in Czech and Polish lands (from previous Corded Ware migrants) accompanying other lineages indigenous to the region – seems to have happened only after the Bell Beaker expansion into these territories, during the Bronze Age, probably leading to the formation of the Balto-Slavic community, as I predicted based on previous papers. The fact that a sample of R1b-U106 subclade pops up in this territory is interesting from the point of view of a shared substrate with Germanic, as is the earlier BB sample of R1b-Z2103 for its connection with Graeco-Aryan dialects.

All this suggests that a North-West Indo-European dialect – ancestor of Italo-Celtic, Germanic, and Balto-Slavic -, supported in Linguistics by most modern Indo-European schools of thought, expanded roughly along the Danube, and later to northern, eastern, and western Europe with the Bell Beaker expansion, as supported in Anthropology by Mallory (in Celtic from the West 2, 2013), and by Prescott for the development of a Nordic or Pre-Germanic language in Scandinavia since 1995.

Maybe more importantly, the fact that only Indo-Iranian-speaking Sintashta-Petrovka (and later Andronovo) cultures were clearly associated with R1a-Z645 subclades, and rather late – after mixing with early Chalcolithic North Caspian steppe groups (mainly East Yamna and Poltavka herders of R1b-L23 subclades) – gives support to the theory that Corded Ware (and probably the earlier Sredni Stog) groups did not speak or spread Indo-European languages with their migration, but most likely Uralic – as seen in recent papers on the much later arrival of haplogroup N1c – (compatible with the Corded Ware substrate hypothesis), adopting Indo-Iranian by way of cultural diffusion or founder effect events.

As Sheldon Cooper would say,

Under normal circumstances I’d say I told you so. But, as I have told you so with such vehemence and frequency already the phrase has lost all meaning. Therefore, I will be replacing it with the phrase, I informed you thusly

The Great Hungarian Plain in a time of change in the Balkans – Neolithic, Chalcolithic, and Bronze Age


I wrote recently about Anthony’s new model of Corded Ware culture expansion from Yamna settlements of Hungary. I am extremely sceptic about it in terms of current genetic finds, and suspicious of the real reasons behind it – probably misinterpretations of the so-called ‘Yamnaya ancestral component’ in recent genetic papers, rather than archaeological finds.

Nevertheless, it means a definitive rejection by Anthony of:

  • The multiple patron-client relationships he proposed to justify a cultural diffusion of Late Indo-European dialects from Yamna into different Corded Ware cultures in the forest-steppe and Forest Zone (see one of his latest summaries of the model in 2015). Now the language change is explained as a pure migration event, and cultural diffusion is not an option. Ergo, if no migration is found from Hungarian Yamna into Lesser Poland, then Corded Ware cultures were not Indo-European-speaking.
  • Ringe’s glottochronological tree for Proto-Indo-European languages (Ringe, Warnow, and Taylor 2002). An early and sudden split of Late PIE dialects in all directions is substituted by a common, Old European language that expanded from a very small area of settlers, in the Carpathian Basin. This is coincident with the current view on North-West Indo-European, and I think that his final acceptance of a sound linguistic model is essential to solve Indo-European questions.
  • The simplistic assumption of Yamna -> Corded Ware -> Bell Beaker migration found in genetic papers of 2015. The new model implies Yamna->Yamna settlers (Eastern Hungary). Yamna settlers are known to have developed into East Bell Beakers (as described by Gimbutas and accepted by Anthony originally, and now also found in the adoption of Heyd’s theory for his new model); therefore a Yamna settlers (Hungary) -> East Bell Beaker evolution is evident and mainstream, now clear also in genetics. It remains to be seen if the additional Yamna settlers (Hungary) -> Proto-Corded Ware migration proposed by him as a novelty in this new model is also right, i.e. if Yamna settlers from Hungary did in fact migrate into sites of Lesser Poland (to form a Proto-Corded Ware culture). If not, then only Heyd’s model remains.

This new model offers thus a more suitable time frame for usual proto-language guesstimates, that would be compatible with a spread of Late Indo-European with Yamna settlers (of R1b lineages) from the steppe into a small region, where North-West Indo-European would have been spoken, and then a potential cultural diffusion through (or founder effect in) a Proto-Corded Ware culture (of R1a-M417 subclades) of Lesser Poland, which is compatible with the Corded Ware Substrate hypothesis.

Since Anthony has stuck his neck out in favour of this new theory – changing some of his popular theories, and rejecting what many geneticists seem to take as certain – , and because of his previous impressive improvements over Gimbutas’ simple steppe theory (now apparently fashionable again), I think he deserves that his proposal of Yamna/Late Indo-European expansion in the Balkans be further investigated, if only to be improved upon.

I recently found the paper 4000-2000 BC in Hungary: The Age of Transformation, by T. Horváth, in Annales Universitatis Apulensis. Series Historica, 20/II, 51-113. While it deals mainly with the potential survival of the Baden culture into the late third millennium BC, it gives some interesting quite early dates for Yamna (‘Pit’) graves in the Carpathian Basin, and potential cultural (and population) movements within the Balkans.

A note about the Corded Ware culture in the Carpathian Basin:

Many researchers may assume that it is unnecessary for us to deal with the Corded Ware and Globular Amphorae cultures of north Germany, Poland and Denmark, and if so it does not matter what the names of the periods are. It actually matters a lot. It is true that in these areas there was no Baden complex, but the period had many Baden (and other) culture “period phenomena”. These seem to part of a larger formation than cultures – evidenced by traces such as cattle burials, the relationship between copper metallurgies and jade – which link these territories even when the culture complexes were different, because these phenomena appear not just in the Baden, but in the Corded Ware and Globular Amphorae area as well (and these cultural complexes partly overlapped each other both in space and time!). Even the characteristics of sites show many similarities: e.g. in the northern part of corded ware distribution area, mainly burials have been discovered (similarly to the Pit Grave culture in the Great Hungarian Plain) and in the southern part only settlements appear.

At the moment we have no explanation regarding the nature of the relationship between them (it is supposed that as a result of geographical conditions the people of the same culture lived in different ecological conditions and they adapted differently to their environment). In considering the whole of Europe around 3500-3000 BC, easily observable settlement signs disappeared (Milisauskas and Kruk, “Late Neolithic/Late Copper Age,” 307), similarly to Hungary, even though in Hungary this occurred from the end of the Middle Copper Age to the Early Bronze Age, between 4000 and 2000 BC. If we do not take into account that the cattle burials of the Baden culture between 3600 and 2800 BC, and possibly even longer than that, have analogies with the cattle burials of areas in the Early and Middle Neolithic Corded Ware culture (because “logically” analogies would be sought in those areas in the Bronze Age but this period is not analogous with that period in those areas), we would not find any spiritual resemblance in their relationships that lies behind their spatial and temporal analogies; cf. comp. Niels Johannsen and Steffen Laursen, “Routes and Wheeled Transport in Late 4th-Early 3rd Millennium Funerary Customs of the Jutland Peninsula: Regional Evidence and European Context,” PZ 85 (2010): 15-58; Horváth “The Intercultural Connections of the Baden „Culture,” 118. It is painful to think about how many relationships we have not explored or even assessed yet!

One version from both maps shown in the article, by T. Horváth: “Since the two cultures surely lived together in the Late Copper Age, their collective map represents the Late Copper Age (supplemented with Vučedol sites). Since the direction of diffusion of the Kostolac ceramic style is still unclear, two map versions were made. On one the Kostolac followed the Danube River, on the other they diffused in the opposite direction. In northeast Hungary, Coțofeni III appeared. On this map Kostolac sites are not depicted as dots but, in light of their position and density, proportionately sized arrows are used.”

On Yamna culture and burials in the Carpathian Basin:

Looking at Pit Grave kurgans on the distribution map, it is apparent that burials are the densest where there were no Boleráz or Baden occupations (in this respect this was a kind of “no man’s land”, but from the whole Late Copper Age perspective it was not: the sites of the Baden complex and Pit Grave complemented each other and even partially overlapped). Apart from burials, no Pit Grave settlements or other types of Pit Grave sites are known in Hungary, therefore we do not know whether Pit Grave settlements were situated near the kurgans or whether were somewhere else entirely and we simply have not found them yet.

Since the Pit Grave people had a different lifestyle from the Baden, we can assume that, up to the line of the Tisza River, small animal-keeping mobile groups (Pit Grave) met more populated and settled, agriculturalist, indigenous Boleráz-Baden groups. Animal keepers (Pit Grave) settled in areas where agriculturalists (Boleráz and Baden) did not; in some places, however, they crossed each other’s paths (Fig. 5, 7). Sometimes their sites are very close to each other, sometimes they appear on one site and they can be identified in the stratigraphy of a site. In the latter case the kurgan is always situated on top of a Baden settlement, indicating that Pit Grave not only followed the Baden at these sites but may have represented a somewhat higher social power and belief system than the Baden.

The relationship between pastoral, patrilineal, combatant nomadic tribes and agriculturalist communities is often described as some sort of patron and client relationship. In reality, the signs of such assumption are not visible in the Pit Grave-Baden relationship. There are cases when more aggressive herders conquered more developed agriculturalist communities, but there are also cases when the conqueror’s culture was more developed or stronger than that of the conquered. Always, the conquering nomads are the patrons, the rulers and the empire builders.

In our case, timing is important. How much time had passed on those common sites where a Baden settlement was followed by a Pit Grave kurgan? In these cases, it is certain that the kurgan is younger, but how much younger?

From the article, by T. Horváth. “On the 10 locations analysed, surviving Baden can be assumed after 2800 BC. Unfortunately, it is not possible to predict which sites would survive further scrutiny of radiocarbon dating in this respect; only a few dates are available so far. Therefore, on the map of Baden that still existing after the Late Copper Age, I have also represented all sites (up to the Danube River line) and combined them with Early Bronze Age sites. Since the majority of Makó sites are represented by only one find (scattered finds), and the majority of sites have just one grave, it is impossible to ascertain whether it was part of a cemetery, was within a settlement, or was an individual burial without any further features. Therefore, following Dani 2005, I utilized subdivisions: perhaps in the future this fine subdivision will provide a meaningful explanation (1). Since the radiocarbon dates of Pit Grave kurgans clearly show that the Pit Grave survived at least until 2500 BC, I combined the previous map with that of the Pit Grave. This map would show a realistic picture of cultures after 2800 BC east of the Danube River (2).”

To sum up, the Pit Grave and Baden in the Late Copper Age were certainly contemporary from 3350 BC in the Great Hungarian Plain, and they had common sites, sites which were very close to each other, sites which were far from each other, and also independent sites. The Pit Grave culture surely survived in the transitional period, and into Early Bronze Age I, but perhaps even longer. For the most part, the Baden had ended by 2900 BC in the Great Hungarian Plain. Mapping and some other data (e.g. the discovery that Younger-type, not Mondsee-type, metal objects, which can now be considered to be Baden, even appear east of the Danube River) does not exclude the possibility of searching further for traces of Baden surviving in the Great Hungarian Plain together with or alongside to the Pit Grave. On the common Baden-Pit Grave sites, even without carbon dating, we can assume from already known stratigraphical data that they closely followed each other in time.

For those of you interested in more detailed radiocarbon analysis and assessment of Yamna burials and settlements, from the steppe to the Balkans, to investigate Anthony’s theory further – apart from those authors referenced by him – , I can recommend reading Y. Rassamakin (e.g. Import and Imitation in Archaeology, 2008), S. Ivanova, or Claudia Gerling (e.g. Prehistoric Mobility and Diet in the West Eurasian Steppes 3500 to 300 BC).

Marija Gimbutas and the expansion of the “Kurgan people” based on tumulus-building cultures

An interesting article that I keep stumbling upon, The tumulus in European prehistory: covering the body, housing the soul, by Anthony Harding (2011):

Finally, in Kurgan IV she saw “continuous waves of expansion or raids[that] touched all of northern Europe, the Aegean area, and the east Mediterranean areas possibly as far south as Egypt”. This was the period of the Catacomb Graves, but also the Early Bronze Age rock-cut tombs of the Mediterranean, Vučedol, Bell Beakers in Hungary, the Single Grave culture of the Nordic region. The Kurgan Culture reached Ireland, she remarked in a paper of 1978 “as early as 3500 B.C.” – by which she presumably referred to megalithic mounds covering passage tombs.


According to Gimbutas, the “Kurgan people” are evidenced by single graves in deep shafts, often in wooden chests (coffins) or stone cists marked by low earth or stone barrows; the dead lay on their backs with legs contracted; they were buried with flint points or arrowheads, figurines depicting horses’ heads, boars tusk ornaments and animal tooth pendants. Human sacrifice was allegedly performed during the funeral ceremonies,and sometimes ritual graves of cattle and other animals were added. This is said to contrast with what Gimbutas called the culture of Old Europe (i.e. the earlier Neolithic of the Balkans), who “betray a concern for the deification of the dead and the construction of monumental works of architecture visible in mortuary houses,grave markings, tumuli, stone rings or stone stelae, and in the large quantity of weapons found in the graves”.


The varying burial traditions of the Early Bronze Age in Central and Eastern Europe (Häusler 1977, fig. 1). Circles: tumuli with the “mound edge principle”. Semicircles: tumuli. Stippling: cremation; other symbols represent inhumation graves, divided according to orientation and sex

Can we really associate the practice of mound-building with a specific people, and assume that the spread of the practice indicates the spread of the people? That is one of the “big questions” of European archaeology, and one which a number of papers in the volume address. My own position is that the practice of tumulus building seems so widespread in time and space that it seems hard to associate it with one particular ethnic group – though I can understand how, in the melting pot that was Early Europe, people could believe this to be the case. There are, however, major arguments against the idea, on archaeological grounds alone – which Häusler’s map indicates very clearly. Burial mode and grave form in Copper and Bronze Age Europe was far too variable for any such simplistic correlation. In any case, what are we to make of the appearance of tumuli in such far-flung places as Japan or North America, where tumuli are very common? It was always unlikely that the megalithic tombs of western Europe were to be associated with movements from the steppe 1000 or 2000 years earlier, and nothing that has happened since Gimbutas was writing has changed that situation

Research has corrected Gimbutas’ opinion on the time of spread of Indo-Europeans, on the role of the horse (see e.g. Anthony 2007) in their expansion, and the unrelatedness of the two main central European Chalcolithic archaeological packages: the Corded Ware package that expanded from the Balkans into north-eastern Europe, and the Yamna package (together with the proto-Beaker package) that evolved into the East Bell Beaker culture.

Extent of migration of the “Yamna package“, from Heyd 2007

However, the shadow of the “Kurgan people” remains in the outdated body of innumerable writings. It was revived with the first attempts at disentangling Europe’s genetic past (based on the role of R1a in expanding Proto-Indo-European).

Particularly strong in that sense is the model set forth by Kristiansen, who was nevertheless aware since his first proposal of the differences between the ‘Kurgan people’ of the steppe and those of the Corded Ware culture, selecting thus an alternative framework of long-lasting human and economic interactions between the “Kurgan people”, the Globular Amphora and Baden cultures with an origin of the culture in the natural region formed between the Upper Dnieper and Vistula rivers.

This idea is continued today, and has been recently linked with the Agricultural Substrate Hypothesis. Originally proposed by Kroonen and linked to the spread of Middle Eastern “R1b1b2” with agriculture, it is now (in Kristiansen et al. 2017 and more recently in Iversen and Kroonen 2017) linked with the expansion of the Corded Ware culture, thus proposing that Pre-Germanic is a branch separated some 6,000 years ago from other branches…

Kristiansen’s (1989) schematic presentation of basic principles of burial positions in the Late Neolithic / EBA cultures in northern Eurasia, following to some extent Häusler (1983)

The linguistic proposal is obviously compatible with mainstream archaeological models – which suggest the introduction of Pre-Germanic in Scandinavia with Bell Beaker peoples -, but since the linguistic proposal alone would probably not make such a fuss without the accompanying genetics, I guess this is the right way to publicise it. I doubt linguists really care about genetics, and I really doubt amateur geneticists will read the linguistic proposal, but who cares.

Kristiansen’s traditional model is obviously in contrast with contemporaneous anthropological writings by Anthony, Heyd, or (Gimbutas’ pupil) Mallory, but is nevertheless becoming a resilient tradition in the interpretation of results in studies of human ancestry in Europe.

I doubt that Gimbutas, who was not very fond of tradition, would be proud of this kind of legacy, though…
