are the great apes, and include four genera: Pongo, Gorilla, Pan and
Homo. The only nonhuman great ape from Asia is the orangutan; all other
ages - Gorillas, chimpanzees and bonobos - are from Africa. Like
gibbons, the great apes lack a tail, have broad thoraces and long arms.
However, they are distinguished from the gibbons in having much larger
body sizes, increased sexual dimorphism, a robust canine, broad ilia,
and a robust fibula. They also are more terrestrial than gibbons,
especially the African apes which rely predominately on terrestrial,
quadrupedal knuckle-walking. Pongo is more arboreal than the African
apes, but do walk on their fist ("fist-walking") when terrestrial.</p>
