| Research Abstract |
Severe osteophytes on the body of the lumbar vertebrae were more frequently seen in the Okhotsk males. Degenerative changes of the articular process of the Okhotsk were most frequently seen in the lumbar vertebrae. This is well contrasted with a high frequency of degenerative changes of cervical apophyseal joint in Ryukyu peasants. High prevalence of elbow and knee joint changes in the Okhotsk showed a strong contrast with the high frequencies of the hip joint changes in materials from the Kamakura and those in shoulder and hip joints in materials from Ryukyu. Northern Asian groups tended to possess overall larger limb dimensions than groups from Japan. The Jomon femoral head breadth and skeletal limb lengths were found to be significantly and positively correlated with latitude, indicating a north-south geographical cline in the body size. The A-STR showed uniqueness of the Ainu, and the Y-STR haplotypes revealed strong evidence for a link between the two indigenous populations in Hokkaido and the Ryukyu Islands.
