New preprint Kinship, acquired and inherited status, and population structure at the Early Bronze Age Mokrin necropolis in northern Serbia, by Zegarac et al. bioRxiv (2020).
Intersesting excerpts about this 2100-1800 BC cemetery (emphasis mine):
The individual Mokrin genomes are best modelled as a mixture of Central European hunter-gatherers, Aegean Neolithic farmers and influences from the Eastern European steppes (mean qpAdm tail probability individually 0.46, pooled 0.08).
We observed no significant variation in the eastern European steppe-like component between individuals. Pooling individuals, admixture proportions are estimated to be around 8% (± 1.2% SE) western hunter gatherers, 55% (±

Yesterday the Eaton Lab at Columbia University announced on Twitter a nifty little tool by Carlos Alonso Maya-Lastra called TreeToM, which accepts Newick trees and CSV latitude/longitude data to explore phylogeny and geography interactively, with no coding required.
I thought it could complement nicely my All Ancient DNA Dataset, particularly for those newly described SNPs (FTDNA private variants, etc.) that have not been incorporated yet into SNP Tracker.
Here are two examples with snippets to copy&paste to the appropriate boxes in TreeToM. Feel free to add others in the comments:… Read the rest “Visualizing phylogenetic trees of ancient DNA in a map”
New paper (behind paywall) Ancient Rome: A genetic crossroads of Europe and the Mediterranean, by Antonio et al. Science (2019).
The paper offers a lot of interesting data concerning the Roman Empire and more recent periods, but I will focus on Italic and Etruscan origins.
NOTE. I have updated prehistoric maps with Y-DNA and mtDNA data, and also the PCA of ancient Eurasian samples by period including the recently published samples, now with added sample names to find them easily by searching the PDFs.
