I have recently written about the spread of Pre-Yamnaya or Yamnaya ancestry and Corded Ware-related ancestry throughout Eurasia, using exclusively analyses published by professional geneticists, and filling in the gaps and contradictory data with the most reasonable interpretations. I did so consciously, to avoid any suspicion that I was interspersing my own data or cherry picking results.
Now I’m finished recapitulating the known public data, and the only way forward is the assessment of these populations using the available datasets and free tools.
Understanding the complexities of qpAdm is fairly difficult without a proper genetic and statistical background, which I … Read the rest “Bell Beakers and Mycenaeans from Yamnaya; Corded Ware from the forest steppe”
New open access paper Mapping human mobility during the third and second millennia BC in present-day Denmark by Frei et al. PLOS One (2019), from the Copenhagen group (including Allentoft, Sikora, and Kristiansen) of samples whose genomic profile will probably be published soon.
Interesting excerpts (emphasis mine):
We present results of the largest multidisciplinary human mobility investigation to date of skeletal remains from present-day Denmark encompassing the 3rd and 2nd millennia BC. Through a multi-analytical approach based on 88 individuals from 37 different archaeological localities in which we combine strontium isotope and radiocarbon analyses together with anthropological investigations, we explore

Open access Population genomics of the Viking world, by Margaryan et al. bioRxiv (2019), with a huge new sampling from the Viking Age.
Interesting excerpts (emphasis mine, modified for clarity):
To understand the genetic structure and influence of the Viking expansion, we sequenced the genomes of 442 ancient humans from across Europe and Greenland ranging from the Bronze Age (c. 2400 BC) to the early Modern period (c. 1600 CE), with particular emphasis on the Viking Age. We find that the period preceding the Viking Age was accompanied by foreign gene flow into Scandinavia from the south and east:

I said I would write a post about topo-hydronymy in Europe and Iberia based on the most recent research, but it seems we can still enjoy some more discussions about the famous Vasconic Beakers, by people longing for days of yore. I don’t want to spoil that fun with actual linguistic data (which I already summarized) so let’s review in the meantime one of the main Uralic-Indo-European interaction zones: Scandinavia.
One of the many eye-catching interpretations – and one of the few interesting ones – that could be found in the relatively recent article Talking … Read the rest “Pre-Germanic and Pre-Balto-Finnic shared vocabulary from Pitted Ware seal hunters”
After some really interesting fantasy full of arrows, it seems Kristiansen & friends are coming back to their most original idea from 2015, now in New Scientist’s recent clickbait Story of most murderous people of all time revealed in ancient DNA (2019):
Teams led by David Reich at Harvard Medical School and Eske Willerslev at the University of Copenhagen in Denmark announced, independently, that occupants of Corded Ware graves in Germany could trace about three-quarters of their genetic ancestry to the Yamnaya. It seemed that Corded Ware people weren’t simply copying the Yamnaya; to a large degree they

Some interesting studies were published at roughly the same time as Damgaard et al. (Nature 2018 and Science 2018), and that’s probably why they got little attention (at least by me).
Monica H. Green (also in Academia.edu), specialized in History of Medicine, summed up their relevance in Twitter quite well (her text is edited here for clarity):
I’ve been disappointed that three recent exceptional studies of one of the world’s most historically important diseases, leprosy, have gotten so little notice from the science communication. It will take me a few hours to lay out their significance. But

Open access Ancient DNA study reveals HLA susceptibility locus for leprosy in medieval Europeans, by Krause-Kyora et al., Nature Communications (2018)
Leprosy, a chronic infectious disease caused by Mycobacterium leprae (M. leprae), was very common in Europe till the 16th century. Here, we perform an ancient DNA study on medieval skeletons from Denmark that show lesions specific for lepromatous leprosy (LL). First, we test the remains for M. leprae DNA to confirm the infection status of the individuals and to assess the bacterial diversity. We assemble 10 complete M. leprae genomes that all differ from each other. Second,
