Document Summary
Analogies: the study of non-human primate biology & behavior, structures that are superficially similar. Do not pass through similar stages during embryonic development. Organisms do not share a common ancestor. Homologies: structures possessed by 2 different organisms that arise in a similar fashion. Pass through similar stages during embryonic development. Ex: forearm vs front leg of your dog. Humorous, ulna, and radius also present in dog leg. All primates: homologies: kingdom, phylum, class, order. Subphylum: aminalia, chordata, vertebrata, mammalia, primate o.
