説明

Paying attention to the importance of foot grasping of the primate to its arboreal locomotion, 9 angles and 15 lengths of tarsal and metatarsal bones belonging to 14 anthropoidea genera were measured to show the features of the grasping foot skeleton, to classify the primate foot, and to study the relations between the morphology of the foot and locomotion.<br>The results disclosed that the foot skeleton of the apes possesses grasping features, namely 1) low transverse arch, 2) slight medial torsion of the caput of the 1st metatarsal, 3) strong lateral torsion of the caputs of the lateral 4 metatarsals, 4) large opposability of hallux, 5) long hallucial metatarsal relatively to the others, and 6) large height-breadth indices of the lateral 4 metatarsal caputs. The foot skeleton's features of the small New World monkeys and the Old World monkeys are opposite to the grasping ones. Furthermore, those of the large New World monkeys are intermediate probably because of their prehensile tails, and those of Homo are unique. And it is suggested that the grasping foot is an adaptation for climbing especially during feeding.
