R1b-rich earliest Corded Ware, a Yamnaya-related vector of Indo-European languages

New open source paper, Dynamic changes in genomic and social structures in third millennium BCE central Europe, by Papac et al., Science Advances (2021).

Interesting excerpts (emphasis mine):

We report genomic data from the earliest CW individuals to date [show] that CW was widespread across Bohemia by 2900 BCE. The early radiocarbon dates are also supported by these individuals’ genetic profiles, who occupy the most extreme positions on PC2, as expected under a scenario of the earliest CW being migrants from the east who mixed with locals, resulting in intermediate PC2 positions in later generations.

(…)We found poor statistical

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”

Longobards from Scandinavia, and the “Ural-Altaic” Árpád lineage

longobards-antiquity

The Family Tree DNA R&D team formed by Göran Runfeldt and Michael Sager has reported detailed Y-SNPs of sampled Longobards from the open access paper Understanding 6th-century barbarian social organization and migration through paleogenomics, by Amorim et al. Nat. Commun. (2020). From the abstract:

We obtained ancient genomic DNA from 63 samples from two cemeteries (from Hungary and Northern Italy) that have been previously associated with the Longobards, a barbarian people that ruled large parts of Italy for over 200 years after invading from Pannonia in 568 CE. Our dense cemetery-based sampling revealed that each cemetery was primarily organized
