[To the problem of differentiation of north Mongoloids, Caucasoids, and Amerinds on the territory of Eurasia (genetic data)].

The matrix of genetic distances of 11 human populations of Europe, Asia, and America was calculated using data on frequencies of 28 alleles of 12 loci of proteins, enzymes, and blood groups. This matrix and constructed on their basis dendrogram permit one to suggest that the place of division of paleolitic population on ancestors of North Mongoloids, Caucasoids, and Amerinds was in South Siberia and possibly in neighbouring regions of Central Asia. Published data on polymorphism of mtDNA in the human populations of Eurasia and America were analysed. These data support the author's hypothesis.
