Outline of Final Research Achievements

Mitochondrial genome analysis of Neolithic Early to Middle Jomon people were conducted, and the complete sequences were determined from several Jomon individuals. Those mitochondrial haplogroups were classified into M7a and N9b, which are characteristic to Jomon people, and genetic continuity from initial to final Jomon period was confirmed. We also identified new sub-haplogruop M7a3 from Hokkaido Jomon. Though it has been difficult to detect genetic substructure of Jomon people, the new sub-haplogroup implies the genetic substructure among Jomon people from Hokkaido to Okinawa region. We chose well-preserved samples to sequence their nuclear genome, and ~10% of the genome were newly determined.
