Width of Head and Pelvis in Homo

Abstract

IN the American Journal of Physical Anthropology, April-June 1929, Prof. John Cameron cites cranial measurements of numerous races, showing that the female skull is proportionately broader than that of the male. The races measured are Bushman, Hottentot, various groups of negroes, Melanesian, Tasmanian, and Australian. It occurred to me that the adaptive character of a broad pelvis might perhaps be correlated with an increased breadth of the head, the latter being then a secondary consequence of a sexual character of functional importance. The breadth of the head (relative breadth) might again perhaps have other consequences.
