Abstract

Early hominid feet are often very fragmentary preserved and their architectural approaches stayed limited and subject to controversy. This study proposes an architectural analysis of the primate foot realised on dislocated skeleton. It is based on the angular analysis of geometrical relationships between the joint areas. We investigate the longitudinal structure of the primate foot and we present the results concerning someAustralopithecus afarensis specimens from Hadar (Ethiopia) and theHomo habilis Olduvai Hominid 8 foot (Tanzania). The architectural analysis argues for the lack of a longitudinal medial arch inA. afarensis, their joints being in neutral position. On the contrary, the more recent OH8 specimen is arched both medially and laterally.
