| Research Abstract |
1 Judging from the findings of cranial and dental morphological analyses, the Epi-Jomon inhabitants in Hokkaido were confirmed to have been phylogenetically transitional from the Jomon in eastern Japan to recent Hokkaido Ainu.
2 The limb bone morphology of the Epi-Jomon was basically identical to that of the Jomon in eastern Japan and the antero-posterior flatness of the upper part of the femur, characteristic of the Ainu, had already appeared in the Jomon and Epi-Jomon in Hokkaido.
3 The configuration of subtalar articular facets of the calcaneus indicated that the Jomon and Epi-Jomon inhabitants in Hokkaido had a lifeway adapted more to hunting and gathering than the Jomon in western Japam.
4 Extremely high incidence of N9b haplogroup in mtDNA was observed in the Jomon and Epi-Jomon in Hokkaido and this distribution pattern of haplogroup was quite different from that of modern Japanese in Honshu.
5 Based on the findings of tooth size proportion and mtDNA, two juvenile skeletons (3A and 3B) from a double burial at the Usu-Moshiri site were considered to be sibling, however, the kinship of two adult couples (16A and 16B ; 7M and 7F) from other two double burials were not acknowledged
6 The AMS dating using the human skeletal remains from the Usu-Moshiri site confirmed that these individuals lived in the periods from the end of Final Jomon to the beginning of Epi-Jomon.
7 The analyses of stable isotope (C and N) demonstrated that the inhabitants of the Usu-Moshiri site took major protein resources from sea mammals such as fur seal and sea lion.
