Research Abstract

Molar enamel thickness and crown morphology has been compared in detail for fossil and extant hominid and hominoid species. Molar morphology of the Miocene ape Chororapithecus shows a similar functional adaptation with extant gorilla. Extant two species of the genus Pan share a unique pattern of enamel distribution such that the occlusal basin enamel is remarkably thin. This pattern is not seen in the molars of Ardipithecus ramidus, a 4.4. mya hominid species.
