Scientific work.
Coppens is one of the co-discoverers of Lucy along with Donald Johanson and Maurice Taieb.
He is currently Professor at the College de France, which is considered to be France's most prestigious research establishment. 
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 former director of the Hadar expedition. Donald Johanson, who lead the 1974 expedition, was the one who found Lucy. 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
