title: Dental microwear and mechanisms in early hominids from Laetoli and Hadar.
abstract: The dentition of early hominids from Laetoli and Hadar provide evidence of "incisal stripping" and a shear-grinding action for C/P3 complex through microscopic examination of wear facets on dental crowns. This masticatory pattern of dental wear resembles that of Papio papio and suggests behavioral analogies between early hominids and Papio.
