Human beings depend more on technology than any other animal-the use of tools and weapons is vital to the survival of our species. What processes of biocultural evolution led to this unique dependence? Steven Kuhn turns to the Middle Paleolithic (Mousterian) and to artifacts associated with Neandertals, the most recent human predecessors. His study examines the ecological, economic, and strategic factors that shaped the behaviour of Mousterian tool makers, revealing how these hominids brought technological knowledge to bear on the basic problems of survival. Kuhn's main database consists of assemblages of stone artifacts from four caves and a series of open-air localities situated on the western coast of the Italian peninsula. Variations in the ways stone tools were produced, maintained, and discarded demonstrate how Mousterian hominids coped with the problems of keeping mobile groups supplied with the artifacts and raw materials they used on a daily basis. Changes through time in lithic technology were closely tied to shifting strategies for hunting and collecting food. Some of the most provocative findings of this study stem from observations about the behavioural flexibility of Mousterian populations and the role of planning in foraging and technology.
