Subsistence strategies during the Late Pleistocene in the southern Cape of South Africa: Comparing the Still Bay of Blombos Cave with the Howiesons Poort of Klipdrift Shelter.

The Still Bay (SB) and Howiesons Poort (HP) were two significant techno-complexes in the Middle Stone Age and key periods in the expression of behavioral complexity. In this study, we compare the recently excavated fauna from the SB layers at Blombos Cave (BBC) with that from the HP levels at Klipdrift Shelter (KDS) in the southern Cape of South Africa. We consider our findings in the framework of recent models for early human subsistence behavior. In particular, we link our study with models involving resource intensification to examine whether foraging strategies in the HP were more or less intensive than those in the SB. Based on our criteria used to assess intensification-the exploitation of low-ranked prey, the processing of low-utility elements, transport decisions, and occupational intensity-intensive subsistence strategies are more evident at KDS than BBC. Our results suggest that low-ranked elements were processed more heavily and diet breath was broader at KDS than at BBC. However, foraging ranges may have been more extensive at BBC than at KDS. Taphonomic data also suggests that the SB at BBC was a low-intensity, sporadically occupied period in contrast to the high-intensity occupations during the HP at KDS. We argue that this may be related to differences in mobility and residential patterns between these techno-complexes.
