Document Summary
Hominoids: geographic distribution: africa and asia (everywhere for humans, body size range: 13-385 pounds(or more, activity pattern: all diurnal, locomotion: suspension, knuckle-walking, bipedalism, diet: fruit, leaves, insects, meat, seeds, 5 genera: hylobates, pongo, gorilla, pan, homo. Derived hominoid traits larger brain loss of tail long arms: broad thorax. Miocene apes locomotion: arboreal quadrupedalism, terrestrial quadrupedalism, suspension, diet, fruigivory, folivory, seed eating. What happened to all the apes: global cooling restricted forested environments to the tropics. In the more open habitats, apes were unable to compete with the cercopithecoids. Derived human traits: obligately bipedal, small canines, broad dietary niche and tool use, extended time to maturity.
