I have discovered a great dataset from Rasmussen et al. (2010). The data had been used before in conjunction with an ancient DNA sequence, but for me it is invaluable, as it fills up one of the major holes in Eurasia, namely Siberia, and includes a number of Altaic, Uralic, and other North Eurasian people. I suspect that this will be invaluable in fine-tuning the Northeast Asian ancestry of Dodecad Project members.
To begin with, after I processed the data, I ran ADMIXTURE on it up to K=7. Below you can see the results for K=7:
I'm no expert in linguistics, but it's clear to me that the light blue component corresponds to Altaic speakers. It will be extremely interesting to see what the analysis including other Altaic speakers from my other datasets as well as West Eurasians of Uralic/Altaic language or with "Northeast Asian" admixture will show.
The table below has sample sizes and admixture proportions.
Stay tuned. More to come.
