Dene-Yeniseian, Eskimo-Aleut, and Chukotko-Kamchatkan

This post is part of a draft on South Siberian language homelands and Sprachbünde.

At least three major genetic changes have been described to date involving the Lena and Kolyma regions in East Siberia, and all are probably associated with some of the archaeological and linguistic developments that led to the known Early Modern distribution of languages in the Russian Far East and in Northern America.

The following is a tentative description of such intertwined linguistic-archaeological-genetic developments, based on the few available data from each field. For this guesswork, first genetic-archeological results, and then plausible … Read the rest “Dene-Yeniseian, Eskimo-Aleut, and Chukotko-Kamchatkan”

Afanasievo ancestry reached Lake Baikal; Nganasan ancestry origins still at large

New paper (behind paywall) Paleolithic to Bronze Age Siberians Reveal Connections with First Americans and across Eurasia, by Yu et al. Cell (2020)

Interesting excerpts (emphasis mine, paragraphs subdivided for clarity):

Population Structure (PCA)

Most of the Lake Baikal individuals occupied the space on a “ANE-NEA” cline running between “Northeast Asian” (NEA) ancestry represented by Neolithic hunter-gathers from the Devil’s Gate in the Russian Far East (Sikora et al., 2019, Siska et al., 2017), and the ANE ancestry represented by Upper Paleolithic Siberian individuals MA1, AfontovaGora 2 (AG2), and AfontovaGora 3 (AG3) (Fu et al., 2016, Raghavan et al.,

Dzudzuana, Sidelkino, and the Caucasus contribution to the Pontic-Caspian steppe

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 (…)
