Morphological and functional implications of sexual dimorphism in the human skeletal thorax.

abstract：:Pliopithecinae and Crouzeliinae (Primates: Pliopithecidae) are distinguished dentally by the sharper crests, more compressed cusps, larger foveae, and narrower molars of the latter. Traditionally, such differences were qualitatively related to increased folivory in crouzeliines. This was subsequently disproved by micr...
