Apes, collectively Hominoidea (/ˌhɒmɪˈnɔɪdi.ə/; hominoids), are a superfamily of Old World simians native to sub-Saharan Africa and Southeast Asia. They were more widespread in Africa, Asia, and Europe in prehistory, and, including humans, are found globally. Apes are more closely related to Old World monkeys (family Cercopithecidae) than to the New World monkeys (Platyrrhini), with both Old World monkeys and apes placed in the clade Catarrhini. Apes do not have tails due to a mutation of the TBXT gene. In traditional and non-scientific use, the term ape can include tailless primates taxonomically considered Cercopithecidae (such as the Barbary ape and black ape), and is thus not equivalent to the scientific taxon Hominoidea. There are two extant branches of the superfamily Hominoidea: the gibbons, or lesser apes; and the hominids, or great apes.
- The family Hylobatidae, the lesser apes, include four genera and a total of 20 species of gibbon, including the lar gibbon and the siamang, all native to Asia. They are highly arboreal and bipedal on the ground. They have lighter bodies and smaller social groups than great apes.
- The family Hominidae (hominids), the great apes, includes four genera comprising three extant species of orangutans, two extant species of gorillas, two extant species of chimpanzees, and humans.
Except for gorillas and humans, hominoids are agile climbers of trees. Apes eat a variety of plants and animals. Plants, which can include fruits, leaves, stalks, roots, nuts, and seeds, make up the bulk of their diet. Human diets are sometimes substantially different from that of other hominoids, due in part to the development of technology and a wide range of habitation.
