Chimpanzees have a brain size averaging 400 cubic centimeters which is about the same size as our early bipedal ancestors, Australopithecus. Compare this to our brains which average 1100 cubic centimeters. It seems like a big difference, however, the cerebral cortex of a Chimpanzee has large amounts of folds, an indication of their high intelligence level.
