Genetic integration of molar cusp size variation in baboons.

abstract：:A method of drawing outlines of the distal end of the humerus is presented and carried out on some pongids (Pan troglodytes, Pan paniscus, Pongo pygmaeus), on modern man, and on some casts of Plio-Pleistocene hominids. It appears that these outlines are good indicators of the overall morphology and permit the distingu...
