Y-DNA of 129 high quality shotgun ancient samples

ftdna-shotgun-samples-map

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”

Proto-Indo-European kinship system and patrilineality

kinship-systems

Within months, it will be finally confirmed that both Late Repin offshoots – Early Yamnaya and Afanasievo – spread with clans that were dominated by R1b-L23 patrilineages. Succeeding migration events, likely coupled with internal founder effects under the most successful clans, left Indo-Tocharian-speaking clans as an almost uniform community in terms of Y-chromosome haplogroups, with their most recent common ancestor traceable to the 5th millennium BC.

Before that, it seems that the Indo-Anatolian-speaking Early Khvalynsk community was slightly more diverse. In particular, the success of R1b-V1636 lineages is apparent in the Khvalynsk-Novodanilovka expansion, since it is … Read the rest “Proto-Indo-European kinship system and patrilineality”
