Chimpanzee

1. An african ape (Pan troglodytes, formerly Anthropithecus troglodytes, or Troglodytes niger) which approaches more nearly to man, in most respects, than any other ape. It is the most intelligent of non-human animals, and when full grown, it is from three to four feet high. A variant called the pygmy chimpanzee, or bonobo, has been recently recognized as a separate species.
