Climate and Culture in South Africa

South Africa has one of the longest and most-studied archaeological records of human technological, cultural, and subsistence behaviour. In this project we seek to understand the role of climate and environmental change in shaping human adaptations and innovations in this part of the world.

The environments of South Africa have been long thought to have had a considerable impact on the cultural, technological, and subsistence behaviours of our species. On the southern Cape coast of South Africa, evidence for heat-treated stone tool technologies, personal ornamentation, symbolism, and complex subsistence strategies occurs from c. 100 ka. It has been argued that climatic variability forced humans to innovate such behaviours in order to adapt to changing environments and food sources. By contrast, it has also been suggested that climatic and environmental stability in refugia in this region facilitated experimentation. Either way, climate-induced variation in terrestrial and marine environments, clearly exploited by humans in this region, likely had major impacts on behaviour.                                                                                                                               

In the highlands of Lesotho, temperature controls the terrestrial resources available to humans, as well as the possibility of habitation. A rich history of archaeological research in the region provides a record of changing technological strategies, varying subsistence reliance on large game and freshwater fish resources, and changing occupation intensity through time. This region was most likely vulnerable to fluctuations in temperature during the Last Glacial Maximum and across the Terminal Pleistocene/Holocene transition that, in turn, likely played a part in the technological, cultural, and subsistence structure o the archaeological record in this region.

Teasing apart hypotheses relating climate change to human behaviour in this part of South Africa has been hindered by a general lack of high-resolution, ‘on-site’ records of immediate relevance to terrestrial and marine environments exploited by human populations. In this project we seek to develop well-dated, multi-proxy sequences, directly associated with records of human behaviour, in order to test the relevance of climate change to pulses of human innovation, and changes in technological and subsistence adaptations, in this part of the world. The unparalleled length of documented human presence in this region, as well as its long history of archaeological research, make it an ideal context to test new palaeoenvironmental proxies and approaches.
