Directional changes in Levallois core technologies between Eastern Africa, Arabia, and the Levant during MIS 5

Abstract Marine Isotope Stage (MIS) 5, ~ 130 to 71 thousand years ago, was a key period for the geographic expansion of Homo sapiens, including engagement with new landscapes within Africa and dispersal into Asia. Occupation of the Levant by Homo sapiens in MIS 5 is well established, while recent re...
