Sredni Stog, Proto-Corded Ware, and their “steppe admixture”

Once the haplogroups of the announced West Yamna and Yamna settlers in Hungary and Khvalynsk from Ekaterinovka appear, it is to be expected that there won’t be much discussion on the Y-DNA bottlenecks that affected Khvalynsk – Yamna migrations.

So let’s cut to the chase and see where Corded Ware peoples (mainly of R1a-Z645 subclades) got their so-called “steppe admixture” different from that of Yamna. Because, as you might have realized by now, Sredni Stog – and consequently Corded Ware – remains nowadays an undefined (archaeological) mess.

Rassamakin explains it quite well, in the chapter Eneolithic of the Black … Read the rest “Sredni Stog, Proto-Corded Ware, and their “steppe admixture””

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

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

Consequences of Damgaard et al. 2018 (I): EHG ancestry in Maykop samples, and the potential Anatolian expansion routes

This is part I of two posts on the most recent data concerning the earliest known Indo-European migrations.

Anatolian in Armi

I am reading in forums about “Kroonen’s proposal” of Anatolian in the 3rd millennium. That is false. The Copenhagen group (in particular the authors of the linguistic supplement, Kroonen, Barjamovic, and Peyrot) are merely referencing Archi (2011. “In Search of Armi”. Journal of Cuneiform Studies 63: 5–34) in turn using transcriptions from Bonechi (1990. “Aleppo in età arcaica; a proposito di un’opera recente”. Studi Epigrafici e Linguistici sul Vicino Oriente Antico 7: 15–37.), who asserted the potential Anatolian … Read the rest “Consequences of Damgaard et al. 2018 (I): EHG ancestry in Maykop samples, and the potential Anatolian expansion routes”

No large-scale steppe migration into Anatolia; early Yamna migrations and MLBA brought LPIE dialects in Asia

Another, simultaneous paper with the Eurasian samples from Nature, The first horse herders and the impact of early Bronze Age steppe expansions into Asia, by de Barros Damgaard et al., Science (2018).

A lot of interesting data, I will try to analyse its main implications, if only superficially, in sections.

Anatolian samples

Anatolia_EBA from Ovaören, and Anatolia_MLBA (this including Assyrian and Old Hittite samples), all from Kalehöyük, show almost no change in Y-DNA lineages (three samples J2a, one G2a), and therefore an origin of these people in common with CHG and Iranian Neolithic populations is likely. No EHG ancestry … Read the rest “No large-scale steppe migration into Anatolia; early Yamna migrations and MLBA brought LPIE dialects in Asia”

Lazaridis’ evolutionary history of human populations in Europe

Preprint of a review by Iosif Lazaridis, The evolutionary history of human populations in Europe.

Interesting excerpts:

Steppe populations during the Eneolithic to Bronze Age were a mix of at least two elements[28], the EHG who lived in eastern Europe ~8kya and a southern population element related to present-day Armenians[28], and ancient Caucasus hunter-gatherers[22], and farmers from Iran[24]. Steppe migrants made a massive impact in Central and Northern Europe post- 5kya[28,43]. Some of them expanded eastward, founding the Afanasievo culture[43] and also eventually reached India[24]. These expansions are probable vectors for the spread of Late Proto-Indo-European[44] languages

Early Indo-Iranian formed mainly by R1b-Z2103 and R1a-Z93, Corded Ware out of Late PIE-speaking migrations

The awaited, open access paper on Asian migrations is out: The Genomic Formation of South and Central Asia, by Narasimhan et al. bioRxiv (2018).

Abstract:

The genetic formation of Central and South Asian populations has been unclear because of an absence of ancient DNA. To address this gap, we generated genome-wide data from 362 ancient individuals, including the first from eastern Iran, Turan (Uzbekistan, Turkmenistan, and Tajikistan), Bronze Age Kazakhstan, and South Asia. Our data reveal a complex set of genetic sources that ultimately combined to form the ancestry of South Asians today. We document a southward spread of

Proto-Indo-European homeland south of the Caucasus?

User Camulogène Rix at Anthrogenica posted an interesting excerpt of Reich’s new book in a thread on ancient DNA studies in the news (emphasis mine):

Ancient DNA available from this time in Anatolia shows no evidence of steppe ancestry similar to that in the Yamnaya (although the evidence here is circumstantial as no ancient DNA from the Hittites themselves has yet been published). This suggests to me that the most likely location of the population that first spoke an Indo-European language was south of the Caucasus Mountains, perhaps in present-day Iran or Armenia, because ancient DNA from people who

The uneasy relationship between Archaeology and Ancient Genomics

News feature Divided by DNA: The uneasy relationship between archaeology and ancient genomics, Two fields in the midst of a technological revolution are struggling to reconcile their views of the past, by Ewen Callaway, Nature (2018) 555:573-576.

Interesting excerpts (emphasis mine):

In duelling 2015 Nature papers⁶^,⁷, the teams arrived at broadly similar conclusions: an influx of herders from the grassland steppes of present-day Russia and Ukraine — linked to Yamnaya cultural artefacts and practices such as pit burial mounds — had replaced much of the gene pool of central and Western Europe around

Palaeogenomic and biostatistical analysis of ancient DNA data from Mesolithic and Neolithic skeletal remains

lepenski-vir-mesolithic-anatolia-neolithic

PhD Thesis Palaeogenomic and biostatistical analysis of ancient DNA data from Mesolithic and Neolithic skeletal remains, by Zuzana Hofmanova (2017) at the University of Mainz.
Abstract:

Palaeogenomic data have illuminated several important periods of human past with surprising im- plications for our understanding of human evolution. One of the major changes in human prehistory was Neolithisation, the introduction of the farming lifestyle to human societies. Farming originated in the Fertile Crescent approximately 10,000 years BC and in Europe it was associated with a major population turnover. Ancient DNA from Anatolia, the presumed source area of the demic spread to
