摘要: The Lower to Middle Paleolithic transition (~400,000 200,000 years ago) is marked by technical, behavioral, and anatomical changes among hominin populations throughout Africa Eurasia. replacement of bifacial stone tools, such as handaxes, tools made on flakes detached from Levallois cores documents the most important conceptual shift in tool production strategies since advent technology more than one million earlier has been argued result expansion archaic Homo sapiens out Africa. Our data Nor Geghi 1, Armenia, record earliest synchronic use outside are consistent with hypothesis that this occurred independently within geographically dispersed, technologically precocious a shared technological ancestry.
