Between 35,000 and 45,000 years ago, Neanderthals in Europe and Asia were replaced by the first modern humans. Why and how this transition occurred remains somewhat controversial. New research from the journal Science suggests that sheer numbers may have played a large role in modern humans' eventual takeover; archeological data shows that early populations of modern humans may have outnumbered Neanderthals by more than 9 to 1.
Two archaeologists from Cambridge University analyzed data from the Aquitaine region of southern France, which has Europe’s highest density of sites from this era, and one of the most complete archeological records. They used data from three time periods that encompassed the transition between Neanderthals and modern humans: the Mousterian and Chatelperronian eras, during which Neanderthals lived, and the Aurignacian period, which was dominated by modern humans. By examining differences between land use during these time periods, the researchers hoped to determine whether population dynamics played a role in the transition between these two hominins.
