Viking Age town shows higher genetic diversity than Neolithic and Bronze Age

Open access Genomic and Strontium Isotope Variation Reveal Immigration Patterns in a Viking Age Town, by Krzewińska et al., Current Biology (2018).

Interesting excerpts (emphasis mine, some references deleted for clarity):

The town of Sigtuna in eastern central Sweden was one of the pioneer urban hubs in the vast and complex communicative network of the Viking world. The town that is thought to have been royally founded was planned and organized as a formal administrative center and was an important focal point for the establishment of Christianity [19]. The material culture in Sigtuna indicates that the town had intense

On the origin and spread of haplogroup R1a-Z645 from eastern Europe

In my recent post about the origin and expansion of haplogroup R1b-L51, Chetan made an interesting comment on the origin and expansion of R1a-Z645. Since this haplogroup is also relevant for European history and dialectal North-West Indo-European and Indo-Iranian expansion, I feel compelled to do a similar post, although the picture right now is more blurry than that of R1b-L51.

I find it interesting that many geneticists would question the simplistic approach to the Out of Africa model as it is often enunciated, but they would at the same time consider the current simplistic model of Yamna expansionRead the rest “On the origin and spread of haplogroup R1a-Z645 from eastern Europe”
