The long-lasting intertwined ethnolinguistic developments of East Uralic speakers with Palaeo-Siberian populations makes it impossible to split up a post about the evolution of the former without discussing the fate of the latter.
External contacts with other indigenous East Asian languages close to the Altai-Sayan region and Circum-Baikal area are also relevant, but would no doubt turn this post series into an unending task. Therefore, I will focus on the western part of the Baikal Neolithic and Neo-Siberian-related ancestry clines, which seem more relevant for the ancient stages of Ob-Ugric and Samoyed developments.

I have updated the Ancient DNA Dataset, including a lot of new information from – among other sources – the latest version of Reich Lab curated Dataset, now renamed Allen Ancient DNA Resource (AADR). This includes new columns:
- Object-ID: I am now using whenever possible the Master-ID; Version-ID for a quick identification of the ‘best’ sample to include in SmartPCA or ADMIXTURE runs; and Index as a key with a unique reference number for each sample. That should make for enough stable references for any external tool to use the data.
- mtDNA: Added mtDNA coverage

Oral communication Ancient DNA and the New Science of the Human Past by David Reich (March 3, 2021).
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.
This represents the … Read the rest “IBD sharing between Corded Ware and Yamnaya-related populations”
I have been updating the Ancient DNA Dataset with date estimates published in the recent preprint by Sedig, Olalde, Patterson & Reich bioRxiv (2020), and it had a reference to some interesting new samples from Khvalynsk, showing tight family connections.
Information below is taken from the preprint and from the latest version of the Reich Lab’s Allen Ancient DNA Resource (AADR). Information about the three published Khvalynsk samples is taken from Mathieson et al. Nature (2015) supplementary materials, and each ID features a different font color in the text below for clarity’s sake.

The recent preprint on ancient DNA from Veretye, Lyalovo/Volosovo and Fatyanovo from Saag et al. (2020) has been published in Science Advances Vol. 7, no. 4, eabd6535, and with it the BAM files.
Here are the Y-SNP calls from the files, following the FTDNA Haplotree standard, with Fatyanovo individuals in alphabetical order:
- Veretye PES001 from Peschanitsa (ca. 10785–10626 calBC), mtDNA U4a1, Y-DNA R1aM459YP1301(pre-YP1272?), with 2 SNPs derived – YP1306 (T-C, 5 reads) and Y12474 (T-A, 6 reads) – and 46 SNPs ancestral at the YP1272 level. A sample with 5× coverage that

The BAM files from Egfjord et al. (2021) are out, and Y-SNPs of two-year-old Nordic MN_LN/LN migrant Gjerrild 5 (ca. 2284-2035 calBC) were accurately reported, which means that the sample will need to be labelled R1b>L754>L389>(pre-?)V1636, since one derived read Y125110+ (A->G) in this and one ancestral in a Progress2 sample, PG2001, cannot be used to infer anything certain.
NOTE. It has one derived read (A-T) for FT3897 at the R1b>L754>L389>V1636>Y83069 level, but the other 8 SNPs ancestral, which is not really helpful to define a potential pre-Y83069 branch, given the doubts above. A possible relative could … Read the rest “The Last of the Single Gravers”

Gjerrild stone cist
The Gjerrild stone cist in northern Djursland, eastern Jutland, is remarkable for containing the largest and best-preserved assemblage of SGC skeletons known from Denmark. From this follows a unique opportunity to obtain information on the genetic ancestry of people representing the SGC in Denmark. In the cultural history of Neolithic Denmark, northern Djursland is peculiar as this area lacks finds from the final TRB period but

This is an update to the data from Human population dynamics and Yersinia pestis in ancient northeast Asia, by Kılınç et al. Science Advances (2021).
Files have been released, and some of them are huge, so it might take me some time to analyze them all and include specific subclades in the Ancient DNA Dataset.
For the moment, the sample I highlighted in the previous post, kra001 (2336-2135 calBCE), mtDNA C4b1, from burial Nº1 of Nefteprovod-2, is of very good quality, and it would not be surprising if it made its way to YFull’s tree. It can be … Read the rest “Earliest (and basal) haplogroup N-L1026, from East Siberia”

This detailed picture of Caucasian population history shows that the initial assertion in the 2015 papers, namely of a one-way migration from east to west, was a simplification supported by a variant of admixture analyses that featured Yamnaya as one unified genetic element (e.g., Haak et al. 2015, fig. 3), which led to calculations of Corded Ware individuals showing 75% Yamnaya ancestry.
