Are human beings descendents of apes?
Humans are not descendents of chimpanzees, gorillas, or any other ape. But, if we believe in evolution, then we can imagine an ape-like, human-like creature that lived millions of years ago – a common ancestor to modern humans (Homo sapiens) and modern chimpanzees, gorillas, and so on. Louis Leakey sent Jane Goodall to Gombe because he believed the behaviour that is shared by humans and chimpanzees today might have been present in the common ancestor and, probably, the Stone Age hominids whose fossils he discovered.
