   The Yakuts, I think are one of the least variable in terms
of HLA in the region, it raises the prospect of ancient
enclaves in siberia that did not mix with outsiders well.
Eskimoes however have 2 components, 1 minority is clearly from
western asia and the other resembles other east siberian/north
america haplotypes.
