| Research Abstract |
To assess the genetic affinities and the process of the formation of the modern Ainu population, 122 skeletal samples were analyzed using ancient DNA analysis techniques. We retrieved the mitochondrial DNA (mtDNA) sequences and coding region information from 100 remains. Our results indicate that the Siberian input on the Ainu significantly affected their genetic structure, and that the Okhotsk people might be the main source of Siberian mtDNA in the Ainu. These views were also confirmed by an analysis based on nonmetric cranial traits of the Hokkaido Ainu. The core physical makeup of the Hokkaido Ainu was derived from the ancestral population in Hokkaido, the Okhotsk people are considered to have exerted a certain amount of genetic influence on the ethnogenesis of the Hokkaido Ainu.
