Abstract

This study examines feeding biomechanics in modern human crania and those of extinct early members of the human lineage in order to better understand the selective pressures that influenced human craniofacial evolution. Specifically, this study uses finite element analysis to examine: 1) human feeding performance, in terms bite force production and craniofacial strength; 2) intraspecific variation in human feeding biomechanics; 3) feeding biomechanics in fossil hominins, including Australopithecus sediba and Homo habilis, species that are potentially at the root of modern human lineage, and 4) the functional role of purported facial buttresses.
