This book addresses the question of variability in backed bladelet-based technologies. It also examines the role of LSA microlithic industries as adaptive strategies for coping with paleoenvironmental changes in North Africa. The multidisciplinary research activities conducted in caves and open-air sites in North Africa over the past two decades have highlighted the importance of this region for understanding the development of LSA microlithic technologies in Africa. This book, therefore, enriches the debate of origin and the spread of Late Pleistocene microlithic technologies in North Africa...
