DR. PAMELA R. WILLOUGHBY, University of Alberta, Alberta, Canada, received funding in 2008 to aid research on 'The Origins of Behavioral Modernity in Southern Tanzania.' Our species, Homo sapiens, evolved in Africa by the beginning of the Middle Stone Age (MSA), around 200,000 years ago and subsequently spread into Eurasia after 40,000 years ago. By this time they are supposed to have developed complex technology, referred to as the Later Stone Age (LSA) or Upper Palaeolithic. It is hard to examine the MSA to LSA transition in Africa, as it is associated with major climate changes and near-extinction of our founders. However, initial research in rockshelters in the Iringa Region of southern Tanzania demonstrated that this area was a focus of settlement throughout both periods. In the 2008 field season, an archaeological survey and more test excavations were carried out. The survey was to determine where people obtained stone for tool manufacture, and how this changed over time. Only LSA and more recent sources were discovered, supporting the idea that MSA people obtained raw materials from far away. Test excavations carried out on the slopes surrounding the Magubike rockshelter showed that there were few intact cultural deposits. But a new 2.5 metre deep sequence with all cultural periods from the MSA onwards was uncovered directly below the main shelter.
