The hominoids comprise all the apes - gibbons, siamangs, orangutans, gorillas, humans, chimpanzees, and bonobos - in a superfamily that includes two families, eight genera, and 24 species. They have large bodies, long arms, no tail, large brains, and highly derived cognitive abilities that distinguish them from other primates. Nearly all taxa of Hominoidea are threatened with extinction, with one vulnerable species, fifteen endangered species, and six critically endangered species. The other apes' close phylogenetic relationship with humans has motivated decades of research on their ecology, behavior, physiology, morphology, locomotion, phylogeny, and culture with both captive and wild populations.
