What are Great Apes?
Great apes are members of the family Hominidae, which includes humans, chimps, gorillas, and orangutans. There is one species of human (Homo sapiens), two species of chimp (Common Chimpanzee and Pygmy Chimpanzee), two species of gorilla (Western Gorilla and Eastern Gorilla), two species of orangutan (Bornean Orangutan and Sumatran Orangutan), though throughout the last few million years there have been dozens of other great apes, some of which (like Homo neanderthalis) were probably as intelligent as modern humans.
