Orrorin (jan 1, 6100000 BC – jan 1, 5700000 BC)
Description:
Orrorin tugenensis is a postulated early species of Homininae, estimated at 6.1 to 5.7 million years ago and discovered in 2000. It is not confirmed how Orrorin is related to modern humans. Its discovery was used to argue against the hypothesis that australopithecines are human ancestors, as much as it still remains the most prevalent hypothesis of human evolution as of 2012. The name of genus Orrorin (plural Orroriek) means "original man" in Tugen, and the name of the only classified species, O. tugenensis, derives from Tugen Hills in Kenya, where the first fossil was found in 2000. As of 2007, 20 fossils of the species have been found.Added to timeline:
