PLOS—The first modern humans spread across Europe in three waves during the Paleolithic, according to a study* published May 3, 2023 in the open-access journal PLOS ONE by Ludovic Slimak of the CNRS and University of Toulouse III, France.
The archaeological record of Paleolithic Europe leaves many open questions regarding the nature of the arrival of modern humans into the region and the nature of how these newcomers interacted with the resident Neanderthal populations. In this study, Slimak compared records of stone tool technology across western Eurasia to document the sequence of early human activity in the region.
This study primarily focused on comparative analysis of tens of thousands of stone tools from two sites: Ksar Akil in Lebanon and Grotte Mandrin in France, that recently revealed the earliest Sapiens migration in Europe dating to 54,000 years old. The study analyzed their precise technical connections with the earliest modern technologies in the continent. The author identifies a similar sequence of three technological phases in both regions, suggesting three distinct waves of migration of Homo sapiens across Europe.
These trans-Mediterranean technological connections allow for a reinterpretation of the pattern of human arrival in Europe and its precise relations with the Levantine region. Further examination of these apparent phases of human migration will establish a clearer picture of the sequence of events as Homo sapiens spread across the region and, in doing so, gradually replaced Neanderthals.
Slimak adds: “Until 2022, it was believed that Homo sapiens had reached Europe between the 42nd and 45th millennium. The study shows that this first Sapiens migration would actually be the last of three major migratory waves to the continent, profoundly rewriting what was thought to be known about the origin of Sapiens in Europe. Chatelperronian culture, one of the first modern traditions in western Europe and since then attributed to Neanderthals, should in fact signal the second wave of Homo sapiens migration in Europe, impacting deeply our understanding of the cultural organization of the last Neanderthals.”
