International audience. Global biological analyses using large data sets have shown that human biological variation (eg. genetic, morphologic and serogenetic) fit a dispersal model with an African origin, implying that as the geographic distance increases between populations, so too their biological dis-similarity [1].Nevertheless, some biological discontinuity has been revealed in contemporary isolated and ancient populations due to specific population history (population replacement, expansion and contraction), population structure (genetic drift, gene flow.) and local biological adaptation from ancestral patterns [2]. Consequently these biologically isolated populations are considered as “key” populations to understand the different strata of human populations biological history.In this context, at a crossroad between Africa, Europe and Asia, Anatolian population history results in complex and relatively unknown processes, and the study of their biological history is needed to investigate the pattern of population interactions and evolutions which took place in this region. The population excavated at Sagalassos archaeological site (Taurus Mountains, Southwest Anatolia) presents a great interest to explore these issues,especially considering the continuous occupation of the Sagalassos territory since the 10th millennium BP.
