Chimpanzees, gorillas and gibbons, macaques, spider monkeys, capuchins, and others are all frequent bipedal walkers. To define humans categorically as “bipedal” is not enough; to describe them as habitually bipedal is nearer the truth, but habit as such does not leave its mark on fossil bones.

Are apes bipedal or quadrupedal?

Apes on the ground usually travel quadrupedally. They make only occasional use of bipedalism, often in the context of display. Bipedal walking is the normal slow gait of birds, and running is the fast terrestrial gait of many of them.

What other animals are bipedal?

Some examples are baboons, bonobos, chimpanzees and gibbons. Other mammals such as beavers, raccoons, mice and rats squat on their back legs while eating, and raccoons and beavers walk bipedally when carrying things. Other bipedal mammals are rabbits, bears, meerkats and ground squirrels.
