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