An interesting aspect of the paper, hidden among so many relevant details, is a clearer picture of how the so-called Yamnaya or steppe ancestry evolved from Samara hunter-gatherers to Yamna nomadic pastoralists, and how this ancestry appeared among Proto-Corded Ware populations.
It has been known for a long time that the Caucasus must have hosted many (at least partially) isolated populations, probably helped by geographical boundaries, setting it apart from open Eurasian areas.
David Reich writes in his book the following about India:
The genetic data told a clear story. Around a third of Indian groups experienced population bottlenecks as strong or stronger than the ones that occurred among Finns or Ashkenazi Jews. We later confirmed this finding in an even larger dataset that we collected working with Thangaraj: genetic data from more than 250 jati groups spread throughout India (…)
Interesting excerpts (only introduction and conclusions, emphasis mine):
Archaeological setting at the site of Maidanetske, Ukraine
From ca. 4800 to 3350 BCE, Trypillia settlements were widespread over parts of eastern Romania, Moldova and Ukraine (Menotti and Korvin-Piotrovskiy, 2012; Müller et al., 2016; Videiko, 2004). Maidanetske (Fig. 1B) is one of the so-called “mega-sites” which developed during ca. 3900–3400 BCE in central
About two months ago I stumbled upon a gem in archaeological studies related to Proto-Indo-Europeans, the book О скипетрах, о лошадях, о войне: этюды в защиту миграционной концепции М.Гимбутас (On sceptres, on horses, on war: Studies in defence of M. Gimbutas’ migration concepts), 2007, by V. A. Dergachev, from the Institute of Cultural Heritage of the Moldavian Republic.
This is the first time we published the results of a comprehensive study of burial 45 of the eneolithic cemetery called Ekaterinovsky Cape. The burial contains the skeleton of a young man with traumatic injuries of the skull, leg and hand bones of other individuals, skeleton of a young specimen of a domestic goat (Capra hircus) that was abundantly sprinkled with red ocher. Grave goods include three stone
A new paper with open access has appeared in Quaternary Science Reviews, authored by Patton et al.: Deglaciation of the Eurasian ice sheet complex, which offers a new model investigating the retreat of this ice sheet and its many impacts.
According to the comments of professor Alun Hubbard, the paper’s second author and a leading glaciologist:
To place it in context, this is almost 10 times the current rates of ice lost from Greenland and Antarctica today. What’s fascinating is that not all Eurasian ice retreat was from surface melting alone. Its northern and western sectors across the
