Incisor size and diet in anthropoids with special reference to Cercopithecidae

摘要: In 57 species of anthropoids relative size incisors in highly correlated with diet. Anthropoids that feed primarily on large food objects (large fruits) have larger than those smaller (berries or leaves). This difference reflects a need for more extensive incisal preparation before mastication. Extensive causes increased tooth wear, therefore, enlarged are probably an adaptive response to increase their wear potential.
