Yves Coppens

Yves Coppens is most famous for his role in the 1974 discovery of "Lucy," a remarkably well-preserved *Australopithecus afarensis* skeleton. He co-led the expedition in the Afar Triangle of Ethiopia alongside Donald Johanson and Maurice Taieb. This find fundamentally changed our understanding of early hominin bipedalism.

No, Coppens was part of a three-person leadership team that included American paleoanthropologist Donald Johanson and French geologist Maurice Taieb. While Coppens is often associated with the find in France, Johanson was the one who actually spotted the initial bone fragment. The excavation took place in the Hadar formation in Ethiopia.

Coppens proposed the "East Side Story" hypothesis in the early 1980s, which suggested that human ancestors evolved in East Africa due to the Great Rift Valley creating distinct environmental changes. He argued that the tectonic shift created a drier climate on the eastern side, pushing hominins out of the jungle and onto the savanna. This theory was highly influential for decades.

Yes, he was a prominent professor at the prestigious Collège de France in Paris, holding the chair of paleoanthropology and prehistory. He also served as the director of the Musée de l'Homme in Paris during his career. He remained an active public intellectual in French science until his passing in 2022.
