Résumé
Marine Isotope Stage (MIS) 5 and 4 are periods of major cultural innovations in the Middle Stone Age (MSA) of southern Africa. While extensive data is available for the coast, far less is known about the interior, in particular its central plateau. This is likely due to the large geographic extent of this area and a general paucity of caves and rock shelters that can provide long stratigraphic sequences and environmental records. The lack of information and systematic research has hindered our understanding of regional variation and patterns of human dispersal within the subcontinent. Our research at the open-air MSA site of Lovedale situated on the Modder River addresses this issue. Using sediment micromorphology, infrared spectroscopy of bones and sediments, phytolith and faunal analyses, as well as luminescence dating, we have reconstructed the evolution of paleoenvironments in this region at specific points over the last ~80,000 years. Our results help contextualize human occupation and hunting strategies associated with a pre-Howiesons Poort technology that occurred in a wetland environment during a short-lived warm, dry period dated to ~70 ka. These results show that humans settled the grasslands of the central interior at the onset of MIS 4 and confirm the importance of wetlands in human subsistence strategies, especially in times of climatic stress.
