| Research Abstract |
In the present study, we examined the genealogy of 35 Jomon skeletons excavated from the Tohoku region of Japan through ancient DNA techniques.
Of 35 specimens, we obtained mitochondrial DNA data from the tooth of 14 individuals. Haplogroups N9b, M7a and D4b were observed in these individuals, and N9b was the most predominant (50%). The fact that the frequency of M7a in Tohoku Jomons (42.9%) was much higher in Tohoku than in Hokkaido (6.4%) extends a support for the regional difference in the genetic structure among Jomon populations. Moreover, the fact that haplogroups M7a and N9b were frequently observed in Tohoku Jomons as well as in Hokkaido Jomons bore out the hypothesis that these haplogroups are the (Pre-) Jomon contribution to the modern Japanese mtDNA pool. The genetic study of the Jomon population brings important element to the understanding of the origin and formation of Japanese.
