Temporal range: Pliocene - present
|Skull of Homo neanderthalensis|
If an anthropologist wants to includes chimpanzees in the tribe Hominini, then it follows that a sub-tribe is needed to put Australopithecines and humans in. But this is not a majority view at present, and the mainstream view is:
If used, the group includes Sahelanthropus six to eight million years ago.
Because there was no reason to think it would ever have any additional members, Carl Linnaeus did not even bother to define Homo when he first created it for humans in the 18th century. The discovery of Neanderthals brought the first addition.
The genus Homo was given its taxonomic name to suggest that its member species can be classified as human.
