Yves Coppens (born 1934 in Vannes, Morbihan) is a French anthropologist. He graduated from the University of Rennes. He has studied ancient hominids and has had multiple published works on this topic, and has also produced a film.
Coppens is one of the co-discoverers of Lucy along with Donald Johanson and Maurice Taieb, although Richard Dawkins makes the following observation in The Ancestor's Tale: "Incidentally, I don't know what to make of the fact that in his native France, Yves Coppens is widely cited as the discoverer of Lucy, even as the 'father' of Lucy. In the English-speaking world, this important discovery is universally attributed to Donald Johanson." This confusion is because Coppens was the director of the Hadar expedition and so responsible for all of the expedition's finds, whereas Donald Johanson was a participant in the expedition and the one to actually chance on Lucy's skeleton.
The "Rift Valley theory", proposed and supported by the Dutch primatologist Adriaan Kortlandt, became better known when it was later espoused and renamed by Coppens as the "East Side Story". However, this paradigm has been challenged by the discovery of Australopithecus bahrelghazali (Abel) and Sahelanthropus tchadensis by Michel Brunet's team in Toumaï in Chad (2,500 km to west Rift Valley  The asteroid 172850 Coppens is named in his honour.
