| Outline of Final Research Achievements |
Three-dimensional positioning of forelimb and shoulder girdle skeletons were compared among four species of primates. 3D coordinates of landmarks of forelimb and girdle skeletons were digitized for several different forelimb postures. Skeletal model of bone elements were constructed from CT data and fitted to the digitized coordinates of bones. More arboreal primate species showed larger range of forelimb displacement in forward elevation. The curved shape of clavicle substantially determines the dorsal position of scapula, which guarantees a wide range of forelimb swing.
