We identify a genetic ancestry profile in individuals associated with Upper Palaeolithic Gravettian assemblages from western Europe that is distinct from contemporaneous groups related to this archaeological culture in central and southern Europe4, but resembles that of preceding individuals associated with the Aurignacian culture. Modern humans left sub-Saharan Africa at least 60 thousand years ago (ka), and during their initial expansion into Eurasia, they genetically mixed with Neanderthals, resultingin 23% Neanderthal ancestry in the majority of present-day non-African populations5. Here, data really gets to shine, in that its both the source of truth and the driver of insights.

I hope you brings out more courses like these. Svensson, E. et al. Contrary to the proposal in Fu et al.4 but in agreement with Petr et al.17, we do not observe a substantial decrease of Neanderthal ancestry in most European hunter-gatherers through time (Supplementary Information, section6 and Supplementary Figs. Palaeogenomics of Upper Palaeolithic to Neolithic European hunter 1c). In addition, our phylogeographic analysis points to northeastern Italy as the possible entry point of the Epigravettian-associated gene pool in the Italian peninsula. The authors declare no competing interests. CAS ISSN 1476-4687 (online) The incoming Villabruna ancestry later became the most widespread hunter-gatherer ancestry across Europe. Other proposed climatic refugia for human survival during this period are the Italian peninsula, the Balkans and the southeastern European Plain, but the actual genetic contribution of populations from these regions to post-LGM Europeans is highly debated11,12,13.
