Humans are apes. Great apes. Apes all belong to the super-family Hominoidea. The great apes are the family Hominidae which we share with the Chimpanzees, Gorillas and the Orangutan.
Our DNA is less than 2 percent different from that of chimpanzees, so from a biological viewpoint, what is it that makes humans so different from the other great apes? Find out what our ape cousins can do - and what they can't.
Each individual chimpanzee has his or her own distinctive pant-hoot, or call, so that the caller can be identified with precision.
Orangutans have been observed making simple tools to scratch themselves. They also use leafy branches to shelter themselves from rain and sun, and sometimes even drape large leaves over themselves like a poncho.
Chimpanzees are approximately eight times stronger than the average human. Biologically, chimpanzees are more closely related to humans than they are to gorillas.
Bonobos substitute sex for aggression, and sexual interactions occur more often among bonobos than among other primates.
Orangutans' arms stretch out longer than their bodes - over 7 feet from fingertip to fingertip.
