Bipedalism requires adjustments to the inner ear, since bipedal animals must be able to balance on two legs. There are major changes in the feet, which include a reduction in the size of the toes, a non-opposable hallux (big toe), which is relocated in line with the other toes, and the formation of an foot arch (as opposed to flat feet). The redesigned foot forms a platform to be able to support the entire weight of the body.
