Aux origines africaines de l’homme

During the past decade, the palaeontological history of man has been considerably enriched by the discovery of several potential ancestors of humans, gorillas and chimpanzees in Africa allowing a better reconstruction of our phylogenetic tree (even though these data are still under discussion). Thei...
