A chimpanzee is one of the great apes and the closest in intelligence to man. Scientists have examined his mental capabilities and sent him into space before man. Chimpanzees need little description. Being apes and not monkeys, they do not have a tail. Their arms are longer than their legs and they are normally placed on all fours. They may also walk upright with their toes pointed out. When erect, they are 3 to 5 feet tall. The hair is long and coarse, black except for a white patch near the rump. The face, ears, hands, and feet are bare and, except for the black face, the flesh is coloured.

Chimpanzees show great concern for others. When chimpanzees meet after being separated, they greet each other in a very human way by touching or even shaking hands. Chimpanzees have excellent social discipline. When a dominant male arrives, the rest of the chimpanzees rush to pay their respects. The dominant male is not allowed to take food from his inferiors. Group members also spend a considerable amount of time grooming each other and themselves. Mothers check their babies’ fur for foreign particles, dirt, and ticks, and help each other when they get hurt.

Chimpanzees are the best tool users besides men. Sticks 2 to 3 feet long are picked up from the ground or branches of the baalnfnjai, pushed into the nests, and then removed and licked for honey or insects. The stones are nuts and ttecacfc or as projectiles to keep humans and baboons away from their food. Chimpanzees are not only tool makers, but also tool makers. They make their own sticks by plucking the leaves off a twig or ripping them to pieces. Chimpanzees learn all of this by watching how older chimpanzees make and use them. So, man is not easy to make tools, he is simply better than his relatives.
