Homoplasy has been a prominent issue in primate systematics and phylogeny for as long as
people have been studying human evolution. In the past, homoplasy, in the form of parallel …

Many modifications to the mammalian bauplan associated with the obligate aquatic lives of
cetaceans—fusiform bodies, flukes, flippers, and blowholes—are evident at a glance. But …

Morphometric approaches facilitate the analysis of quantitative variation in form, typically
becoming most useful for the study of organisms that have completed morphogenesis and …

In various respects anthropology has developed along paths leading into isolation. It no
longer should hesitate to stake clear claims for all of primatology, now that the comforting old …

The phylogenetic relationship of the Ugandan Miocene hominoid Morotopithecus bishopi to
fossil and living hominoids remains to be determined. In a cladistic approach to this …

Incorporating morphological data into modern phylogenies allows integration of fossil
evidence, facilitating divergence dating and macroevolutionary inferences. Improvements in …

Genetic studies have demonstrated that humans and chimpanzees are sister taxa, with
gorillas, orangutans and gibbons successively more distant. Hominoid similarities suggest …

Character compatibility analysis is founded on the idea that, for the purpos making plausible
reconstructions of evolutionary relationships among the species or other evolutionary units …

A definition of homology, similarity in structure in a group of organisms that delimits that
group alone and that was found in their common ancestor, is discussed. This definition …

The jaw, suprahyoid, and extrinsic tongue muscles are described for eight species of New
World squirrels, spanning more than an order of magnitude in body mass. Anatomical …
