Sex differences in the behavior of nonhuman primates

Abstract

This study recognizes the phylogenetic and morphological commonalities shared by members of a taxonomic unit and suggests that the creatures most similar to ourselves will be those belonging, in order, to: the same species, genus, family, order, class, phylum and kingdom. The more closely allied to our species, taxonomically, presumably the more similar will the animal be. We therefore select nonhuman primates as animal models of choice in studying human problems. © 1978.
