Human technical behavior in the African Middle Stone Age: The lithic assemblage of Porc-Epic Cave (Dire Dawa, Ethiopia)

Abstract

The African origin of modern humans is the center of a large debate. Discoveries of anatomically modern human fossils in Sub-Saharan Africa correlated to lithic and faunal artifacts show that a "modern Behavior" is associated with the emergence of Homo sapiens. Even though the traits to define this modernity are sometimes difficult to apprehend, the study of the Middle Stone Age cultural phase is important for understanding the origin and evolution of the cognitive capacity of modern humans. Porc-Epic Cave in Ethiopia has a long sequence of Upper Pleistocene occupation. Several thousand bone and lithic artifacts were excavated during three major field excavations (1933, 1974, 1975-76). The lithic assemblage reveals that the relationship between humans and their environment is well organized and that the African terminology is sometimes difficult to apply. This paper proposes a synthesis of all the data, studies and conclusions I have made from the analysis of lithic materials from the 1933 and 1975-76 excavations in order to integrate Porc-Epic into the current debate of MSA and modern human Behavior. © 2006 Springer Science + Business Media, Inc.
