The Reich Lab has recently pre-published high quality shotgun sequencing data from 216 ancient individuals within the framework of the Allen Ancient Genome Diversity Project / John Templeton Ancient DNA Atlas. Metadata for the 216 genomes are available here.
Their median coverage is 4.9x, and among them there are 50 high coverage genomes (17-36x), but there are also samples with a coverage similar to the previously published ones.
The FamilyTreeDNA Haplotree team formed by phylogeneticist Michael Sager and Göran Runfeldt from the R&D team has analyzed all 129 males for Y-SNP calls, using – and updating with them – … Read the rest “Y-DNA of 129 high quality shotgun ancient samples”
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”
Open access Genomic Steppe ancestry in skeletons from the Neolithic Single Grave Culture in Denmark, by Egfjord et al. PLoS One (2021).

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

The study of eastern Uralic branches is clearly underdeveloped relative to western ones, and in desperate need of a proper reassessment. This linguistic obscurity contrasts heavily with the decades-long tradition of categorically pinning ethnolinguistic labels (“Ugric” or “Hungarian”) to different prehistorical cultures by (post-)Soviet archaeology, and with the identification of Hungarian as Turkic continuing Turanist trends; 20th century papers showing one of both trends rarely if ever withstand basic scientific scrutiny.
The following is a combination of rewritten excerpts about Ugric in general and Hungarian in particular, as well as some other texts on the linguistic predecessor of the Old … Read the rest “Proto-Hungarian Homeland: East and West of the Urals?”
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”
