Morphological Affinities of Pan paniscus

Abstract
Although the pygmy chimpanzee (P. paniscus) is more similar to man than is the common chimpanzee (P. troglodytes) in some traits, the resemblance is due primarily to the smaller size and concomitant allometric generalization of the former. The 2 spp. of chimpanzees are equally good models for the common ancestry of African apes and man.
