The contribution of Neandertals to the biological and cultural emergence of early modern humans remains highly debated in anthropology. Particularly controversial is the long-held view that Neandertals in Western Europe were replaced 30,000 to 40,000 years ago by early modern humans expanding out of Africa. This book contributes to this debate by exploring the diets and foraging patterns of both Neandertals and early modern humans. Eugène Morin examines the faunal remains from Saint-Césaire in France, which contains an exceptionally long and detailed chronological sequence, as well as genetic, anatomical, and other archaeological evidence to shed new light on the problem of modern human origins.
