Vikings, Vikings, Vikings! Hordes of high quality ancient DNA

vikings-admixture-modern

Recent paper (behind paywall) Population genomics of the Viking world, by Margaryan et al. Nature (2020), containing almost exactly the same information as its bioRxiv preprint.

I have used Y-SNP inferences recently reported by FTDNA (see below) to update my Ancient DNA Dataset and the ArcGIS Online Map, and also to examine the chronological and geographical evolution of Y-DNA (alone and in combination with ancestry).

Sections of this post:

  1. Iron Age to Medieval Y-DNA
  2. Iron Age to Medieval Ancestry
  3. Iron Age to Medieval Y-DNA + Ancestry
  4. FTDNA’s big public debut

Vikings, Vikings, Vikings! “eastern” ancestry in the whole Baltic Iron Age

vikings-middle-age

Open access Population genomics of the Viking world, by Margaryan et al. bioRxiv (2019), with a huge new sampling from the Viking Age.

#EDIT (16 SEP 2020): The paper has been published in Nature.

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

Genetic landscape and past admixture of modern Slovenians

slovenes-snp

Open access Genetic Landscape of Slovenians: Past Admixture and Natural Selection Pattern, by Maisano Delser et al. Front. Genet. (2018).

Interesting excerpts (emphasis mine):

Samples

Overall, 96 samples ranging from Slovenian littoral to Lower Styria were genotyped for 713,599 markers using the OmniExpress 24-V1 BeadChips (Figure 1), genetic data were obtained from Esko et al. (2013). After removing related individuals, 92 samples were left. The Slovenian dataset has been subsequently merged with the Human Origin dataset (Lazaridis et al., 2016) for a total of 2163 individuals.

Y chromosome

First, Y chromosome genetic diversity was assessed. A total of
