I noticed this interesting slide called “Caught red-handed”, at approximately 45m 17s, where David Reich asserts that sampled Corded Ware populations had many “close cousins” with Yamnaya-related populations “within generations”. The method could also be used, always according to Reich, to identify “who the Yamnaya mixed with to form groups like Corded Ware”.
NOTE. Notice also the the number of new sampled individuals from Khvalynsk, Ekaterinovka, and new Yamnaya groups from Chelyabinsk, Urals, Volga, Don, Moldova, and Romania.
1. In the area under discussion, around 4300-4200 BC – a chronological segment marking the evolutionary peak of ‘Old Europe’ (Anthony 2007: 225), represented by the Cucuteni A/ Tripolie BI, Aldeni-Bolgrad, Gumelniţa-Karanovo VI cultures – the first tumular burials appeared (Govedarica 2016: 85). However, flat burials, marked by the existence of some allogeneous elements in the local
It explores one of the main issues we are observing with ancient DNA, the greater reduction in Y-DNA lineages relative to mtDNA lineages, and its most likely explanation (which I discussed recently).
Excerpts interesting for the Indo-European question (emphasis mine):
Gimbutas’s reconstruction has been criticized as fantastical by her critics, and any attempt to paint a vivid picture of what a human culture was like before the period of written texts needs to be viewed with caution. Nevertheless, ancient DNA data
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
