Born on the African continent, Homo sapiens leaves its geographic cradle 100,000 years ago. The European continent is then populated by Neanderthals, so that the two species coexist for about fifteen thousand years. Then, about 30 000 years ago, Neanderthal disappears, while our species continues its conquest of new territories. What do we know today about the arrival ofHomo sapiens in Europe ? Why did he survive, but not Neanderthal? The French prehistorian Nicolas Teyssandier (Traces laboratory, CNRS-University Toulouse-2) brings elements of answer in this video proposed in partnership with Blob, the extra-media.
