Kanzi, 31-year-old Food Cooking Bonobo Chimpanzee

There still is controversy, however. Scientists such as Jared Diamond in The Third Chimpanzee, and Morris Goodman of Wayne State University in Detroit suggest that the bonobo and common chimpanzee are so closely related to humans that their genus name also should be classified with the human genus Homo: Homo paniscus, Homo sylvestris, or Homo arboreus. An alternative philosophy suggests that the term Homo sapiens is the misnomer rather, and that humans should be reclassified as Pan sapiens, though this would violate the Principle of Priority, as Homo was named before Pan (1758 for the former, 1816 for the latter). In either case, a name change of the genus would have implications on the taxonomy of extinct species closely related to humans, including Australopithecus. The current line between Homo and non-Homo species is drawn about 2.5 million years ago, and chimpanzee and human ancestry converges only about 7 million years ago, nearly three times longer ago.
DNA evidence suggests the bonobo and common chimpanzee species effectively separated from each other fewer than one million years ago. The chimpanzee line split from the last common ancestor shared with humans approximately six to seven million years ago. Because no species other than Homo sapiens has survived from the human line of that branching, both Pan species are the closest living relatives of humans and cladistically are equally close to humans.
