抄録

Late Pleistocene Minatogawa people possessed small and slender bodies, with poor muscle development, especially in the upper limbs, indicating adaptation to poor nutrient conditions and moderate stress in manipulation and locomotion. Yet they exhibited stout faces with strong masticatory muscle development resulting from high chewing stress. Minatogawa people are thus regarded to have been adapted to the island environment in the Ryukyu Islands, Japan. Since morphological features of Minatogawa postcranial bones are extremely rare, they might have not evolved into either Jomon people or modem Ryukyuans.
