Nonhuman primates are nevertheless restricted in the use of the hands for communication, since the hands and arms are also critically involved in postural support and locomotion. Most primates are adapted to life in the trees, using their arms for holding onto branches and for swinging from branch to branch. The larger-bodied apes are more terrestrial but move in four-legged fashion over open terrain. Chimpanzees and gorillas, our closest relatives among the primates, adopt a form of locomotion known as knuckle walking, in which the upper body is supported by the knuckles.
