The human brain, in contrast, is about three times larger, with a reported average volume of about 1330 cm3.Ĭhimpanzees reach puberty between the age of eight and ten years. The brain of a chimpanzee has been measured at a general range of 282–500 cm3. Although the jaws protrude, a chimp's lips are thrust out only when it pouts. A bony shelf over the eyes gives the forehead a receding appearance, and the nose is flat. A University of Chicago Medical Centre study has found significant genetic differences between chimpanzee populations.

Both species can walk upright on two legs when carrying objects with their hands and arms. The bonobo has proportionately longer upper limbs and walks upright more often than does the common chimpanzee.

In trees, both species climb with their long, powerful arms on the ground, chimpanzees usually knuckle-walk, or walk on all fours, clenching their fists and supporting themselves on the knuckles. The bonobo is slightly shorter and thinner than the common chimpanzee, but has longer limbs. When extended, the common chimp's long arms span one and a half times the body's height. Male adult wild chimps weigh between 40 and 60 kg with females weighing between 27 and 50 kg. The male common chimp stands up to 1.2 m high. The chimpanzee's arms are longer than its legs.
