The Middle/Later Stone Age transition and cultural dynamics of late Pleistocene East Africa

Abstract

The Middle to Later Stone Age (MSA/LSA) transition is a prominent feature of the African archeological record that began in some places ~30,000-60,000 years ago, historically associated with the origin and/or dispersal of "modern" humans. Unlike the analogous Middle to Upper Paleolithic transition in Eurasia and associated Neanderthal extinction, the African MSA/LSA record remains poorly documented, with its potential role in explaining changes in the behavioral diversity and geographic range of Homo sapiens largely unexplored. I review archeological and biogeographic data from East Africa, show regionally diverse pathways to the MSA/LSA transition, and emphasize the need for analytical approaches that document potential ancestor-descendent relationships visible in the archeological record, needed to assess independent invention, population interaction, dispersal, and other potential mechanisms for behavioral change. Diversity within East Africa underscores the need for regional, rather than continental-scale narratives of the later evolutionary history of H. sapiens.

Keywords: biogeography; chronology; demography; dispersal; lithic technology; obsidian.
