Another preprint came out at the same time as Wang et al. (2020), from the Jena Lab of the Max Planck Society: A dynamic 6,000-year genetic history of Eurasia’s Eastern Steppe, by Jeong, Warinner, et al. bioRxiv (2020).
NOTE. I have now updated the Ancient DNA Dataset, the Prehistory Atlas – with PDF and GIS files including Y-DNA and mtDNA of all newly reported samples (starting with the Neolithic) – as well as the PCA files with those from Wang et al. (2020).
The conclusions are similar, but with some interesting twists. Relevant excerpts (emphasis mine), … Read the rest “R1b-rich Proto-Indo-Europeans show genetic continuity in Asia”
New preprint by the Jena-Reich labs, The Genomic Formation of Human Populations in East Asia, by Wang et al. bioRxiv (2020).
Interesting excerpts (emphasis mine):
Mongolia Neolithic cluster
The three most ancient individuals of the Mongolia ‘East’ cluster are from the Kherlen River region of eastern Mongolia (Tamsag-Bulag culture) and date to 6000-4300 BCE (this places them in the Early Neolithic period, which in Northeast Asia is defined by the use of pottery and not by agriculture). These individuals are genetically similar to previously reported Neolithic individuals from the cis-Baikal region and have minimal evidence of West Eurasian-related admixture

Recent papers The formation of human populations in South and Central Asia, by Narasimhan, Patterson et al. Science (2019) and An Ancient Harappan Genome Lacks Ancestry from Steppe Pastoralists or Iranian Farmers, by Shinde et al. Cell (2019).

I am currently not on holidays anymore, and the information in the paper is huge, with many complex issues raised by the new samples and analyses rather than solved, so I will stick to the Indo-European question, … Read the rest “Yamnaya replaced Europeans, but admixed heavily as they spread to Asia”
A reader commented recently that there is little information about Indo-Europeans from Central and East Asia in this blog. Regardless of the scarce archaeological data compared to European prehistory, I think it is premature to write anything detailed about population movements of Indo-Iranians in Asia, especially now that we are awaiting the updates of Narasimhan et al (2018).
Furthermore, there was little hope that Tocharians would be different than neighbouring Andronovo-like populations (see a recent post on my predicted varied admixture of Common Tocharians), so the history of both unrelated Late PIE languages would have had to be … Read the rest “Proto-Tocharians: From Afanasievo to the Tarim Basin through the Tian Shan”

Celts and hg. R1b
Recent paper (behind paywall) Multi-scale archaeogenetic study of two French Iron Age communities: From internal social- to broad-scale population dynamics, by Fischer et al. J Archaeol Sci (2019).
In it, Fischer and colleagues update their previous data for the Y-DNA of Gauls from the Urville-Nacqueville necropolis, Normandy (ca. 300-100 BC), with 8 samples of hg. R, at least 5 of them R1b. They also report new data from the Gallic cemetery at Gurgy ‘Les Noisats’, Southern Paris Basin (ca. 120-80 BC), with 19 samples of hg. R, at least 13 of … Read the rest “More Celts of hg. R1b, more Afanasievo ancestry, more maps”
The latest papers from Ning et al. Cell (2019) and Anthony JIES (2019) have offered some interesting new data, supporting once more what could be inferred since 2015, and what was evident in population genomics since 2017: that Proto-Indo-Europeans expanded under R1b bottlenecks, and that the so-called “Steppe ancestry” referred to two different components, one – Yamnaya or Steppe_EMBA ancestry – expanding with Proto-Indo-Europeans, and the other one – Corded Ware or Steppe_MLBA ancestry – expanding with Uralic speakers.
The following maps are based on formal stats published in the papers and supplementary materials from 2015 until today, mainly on … Read the rest “Yamnaya ancestry: mapping the Proto-Indo-European expansions”
Master’s thesis Shifting Memories: Burial Practices and Cultural Interaction in Bronze Age China: A study of the Xiaohe-Gumugou cemeteries in the Tarim Basin, by Yunyun Yang, Uppsala University, Department of Archaeology and Ancient History (2019).
Summary excerpts, mainly from the conclusions (emphasis mine):
Both the Xiaohe and the Gumugou groups are suggested as possibly originating from southern Siberia or Central Asia and being related to Afanasievo and Andronovo people (Han 1986, 1994; Li et al. 2010, 2015). But a latest research suggest that the Xiaohe males are genetic distinct from the Afanasievo males, considering the paternal lineages (Hollard et

Open access Siberian genetic diversity reveals complex origins of the Samoyedic-speaking populations, by Karafet et al. Am J Hum Biol (2018) e23194.
Interesting excerpts (emphasis mine):
Consistent with their origin, Mongolic-speaking Buryats demonstrate genetic similarity with Mongols, and Turkic-speaking Altai-Kizhi and Teleuts are drawn close to CAS groups. The Tungusic-speaking Evenks collected in central and eastern Siberia cluster together and overlap with Yukagirs. Dolgans are widely scattered in the plot, justifying their recent origin from one Evenk clan, Yakuts, and Russian peasants in the 18th century (Popov, 1964). Uralic-speaking populations comprise a very wide cluster with Komi
