Levantine Middle Pleistocene blade industries

The origin of Near Eastern Middle Pleistocene blade industries is discussed with reference to the Levallois reduction-technique. Special attention is paid to the Gesher Benot Ya'akov site, in Israel, where the Levallois technology is the earliest in the region (ca 800 ka BP). Whereas later Acheulean industries show no continuity with the Levallois tradition, the alternation of predominant Middle Pleistocene technologies indicates changing adaptation strategies caused by ecological conditions. Accordingly, the early appearance of the laminar technology in the Near East evidences local evolution rather than immigration. The major factors underlying this innovation were adaptation and the intrin sic development of the Levallois system. Laminar technologies, which are first evidenced by certain Levantine sites even earlier than Gesher Benot Ya'akov, became widely distributed at the Acheulo-Yabrudian stage of the late Acheulean. A well-developed blade technology is demonstrated by the Amudian industry of Qesem, Israel, dating to 400-200 ka BP.
