The chimpanzee is an 11-year-old male. He weighs 65 kg and comes from the Kolmården Zoo in Sweden. A chimpanzee’s skeleton is similar to a human’s but differs in a number of ways.
Chimpanzees are the closest living relatives to humans. The male common chimp stands up to 1.2 m high and weighs as much as 70 kg the female is somewhat smaller. The Chimpanzees have much smaller brains than humans and the human brain is about three times larger. On the ground, chimpanzees usually knuckle walk, or walk on all fours, clenching their fists and supporting themselves on the knuckles. Chimpanzees are better suited for walking than orangutans because the chimp’s feet have broader soles and shorter toes.
