The long archeological sequence exposed during our renewed excavations in Hayonim Cave sheds new light on the striking technological changes observed at the boundary between the Acheulo-Yabrudian (end of the Lower Paleolithic) and Early Middle Paleolithic in the Levant, as well as on their meaning in terms of population movements. The recent, as yet unpublished, technological studies highlight a clear technological break between these two entities. In Hayonim, the Acheulo-Yabrudian assemblages found at the bottom of the archeological sequence display the specific combination of bifacial shaping and the production of thick, often cortical, flakes frequently shaped into scrapers by Quina retouch. Neither of these lithic production systems is observed in the succeeding Levantine Middle Paleolithic assemblages. In contrast, the Early Middle Paleolithic is characterized by the expansion and diversification of the Levallois production system in its full-fledged form, the emergence of a specific Laminar technology, and a high proportion of retouched tools made on elongated blanks (points and blades). These technological features are unknown in the previous Acheulo-Yabrudian assemblages in the cave. Based on this information, we attempt to determine if the observed changes in stone tool production strategies resulted from an autochthonous development or a dispersal out of Africa.

Hayonim Cave的Acheulo-Yabrudian和中古旧石器时代（以色列西加利利）：连续还是中断？

我们在哈约宁洞（Hayonim Cave）进行的新一轮发掘中暴露出的漫长考古序列为在黎凡特（Lanter）的Acheulo-Yabrudian（下旧石器时代末期）和中古旧石器时代之间的边界上发现的惊人技术变化提供了新的视角就人口流动而言。最近尚未出版的技术研究强调了这两个实体之间明显的技术突破。在Hayonim中，考古序列底部发现的Acheulo-Yabrudian组合物显示了两面成形和通常由Quina修饰成刮板状的厚，通常为皮质的薄片的生产的特定组合。在随后的黎凡特中古石器时代的组合中都没有观察到这两种石器生产系统。相反，中古旧石器时代的特点是，勒瓦卢瓦（Levallois）生产系统以完整的形式扩展和多样化，出现了特殊的层流技术，并且在细长的坯料（尖头和刀片）上加工了很大比例的修饰工具。这些技术特征在以前的Acheulo-Yabrudian洞穴中是未知的。根据这些信息，我们试图确定观察到的石器工具生产策略的变化是由于本土的发展还是非洲的扩散所致。这些技术特征在以前的Acheulo-Yabrudian洞穴中是未知的。根据这些信息，我们试图确定观察到的石器工具生产策略的变化是由于本土的发展还是非洲的扩散所致。这些技术特征在以前的Acheulo-Yabrudian洞穴中是未知的。根据这些信息，我们试图确定观察到的石器工具生产策略的变化是由于本土的发展还是非洲的扩散所致。
