Révision du sexe des squelettes épipaléolithiques de Taforalt et d'Afalou-bou-Rhoummel par une approche probabiliste

Ce travail a pour objet la réévaluation du sexe des fossiles épipaléolithiques des sites de Taforalt-bou-Rhummel et d¿Afalou, à partir d¿une diagnose sexuelle probabiliste utilisant les données métriques de l¿os coxal. Nous discutons les différences observées avec les diagnoses basées sur squelette crânien et les problèmes généraux rencontrés dans l¿estimation du sexe des fossiles quand l¿os coxal est absent

A genetic history of the Balkans from Roman frontier to Slavic migrations

The rise and fall of the Roman Empire was a socio-political process with enormous ramifications for human history. The Middle Danube was a crucial frontier and a crossroads for population and cultural movement. Here, we present genome-wide data from 136 Balkan individuals dated to the 1st millennium CE. Despite extensive militarization and cultural influence, we find little ancestry contribution from peoples of Italic descent. However, we trace a large-scale influx of people of Anatolian ancestry during the Imperial period. Between 250 and 550 CE, we detect migrants with ancestry from Central/Northern Europe and the Steppe, confirming that ‘‘barbarian’’ migrations were propelled by ethnically diverse confederations. Following the end of Roman control, we detect the large-scale arrival of individuals who were genetically similar to modern Eastern European Slavic-speaking populations, who contributed 30%–60% of the ancestry of Balkan people, representing one of the largest permanent demographic changes anywhere in Europe during the Migration Period
