Cro-magnon "continuity" to later Gravettian culture in Western Europe has just been confirmed.
Out of Africa proponents tried to claim older populations past 40kya had gone extinct, or at least, left no genetic legacy in later European populations.
A discovery and analysis of bone fragments and tools from the Buran-Kaya cave in Crimea (formerly Ukraine, now Russia), confirms earlier Euro-populations including Cro-magnon were ancestral to Gravettians, Solutreans and Magdalenians.
These later European tribes populated western Europe, most especially France and the Iberian Peninsula.
