    Early human social transmission during Marine Isotope Stage 5: a perspective from the Kalahari Basin
    (2024) Maenzanise, Precious; Sahle, Yonatan; Wilkins, Jayne
    The social transmission of cultural information is widely recognized as a crucial component contributing to the survival and prosperity of our species. This thesis studies lithic technological systems to assess the extent of the transmission of cultural information between different early human groups across the Kalahari Basin and adjoining regions during Marine Isotope Stage (MIS) 5 (~130-74 ka), a key time and place for understanding the emergence and expansion of complex behaviors in Africa. It has been proposed that glacial periods (e.g., MIS 4) in southern Africa were characterized by coalescence, while interglacial periods (e.g., MIS 5) were characterized by population fragmentation. While these previous hypotheses represent important examples for testing the degrees of population interconnectedness during MIS 5, they were based primarily on sites outside of the Kalahari Basin and its environs. Therefore, the central inquiry of this thesis is to investigate the presence and extent of cultural transmission among hunter-gatherer populations in and around the Kalahari Basin, assessing whether patterns of population fragmentation observed during MIS 5 are discernible in these regions. This inquiry is achieved by studying lithic assemblages from multiple sites and comparing them using a behavioral approach to cultural transmission. The samples studied are from Ga-Mohana Hill North Rockshelter, Kathu Pan 6, Erfkroon, and Florisbad in South Africa, and ≠Gi and White Paintings Rockshelter in Botswana. The results of this study indicate there are many technological similarities across most of the studied sites, including the predominant use of local raw materials, recurrent Levallois methods, hard hammer percussion technique, core maintenance primarily by débordant removals, manufacturing of similar products, mostly with faceted platforms, and a low frequency of formal tools. This homogeneity may reflect technological information exchange and connections between human groups at these sites. The connectivity is inferred to be closely linked to their adaptation to the drier climatic conditions that persisted in the Kalahari Basin and its adjoining regions, in contrast to coastal and other inland areas. The arid and semi-arid environments may have necessitated the formation of social ties to access scarce and potentially unpredictable resources. In contrast to some other regions that show fragmentation during interglacial periods, the Kalahari Basin and adjacent regions did not follow the same pattern.

    A unified lithic taxonomy based on patterns of core reduction
    (South African Archaeological Society, 2004) Conard, N J; Soressi, M; Parkington, J E; Wurz, S; Yates, R J
    The authors and three students met for workshops on several occasions in Cape Town and Stellenbosch with the goal of defining a taxonomic system for chipped stone artefacts that can be applied to materials from the Early, Middle and Later Stone Age. The motivation for defining a 'unified taxonomy' stems from the need to develop a system for classifying multicomponent surface assemblages. The proposed taxonomy revises southern African systems by applying ideas and methods from European approaches to lithic technology. Given that much confusion exists on the classification of cores and core reduction, the lithic workshops focused on this class of artefact. Most of the variation encountered when examining material from Anyskop, Blombos, Geelbek, Hollow Rock Shelter and Klasies River Mouth could be placed within the taxa of Inclined, Parallel and Platform cores. These categories form the basis of the proposed taxonomy with the additional taxa of Initial, Multidirectional, Indeterminate Broken, Bipolar and Other being necessary for a small proportion of the cores that fall outside the range of the three main taxa. Blind tests using assemblages of cores from Blombos, Geelbek and Anyskop yielded a satisfactory degree of reproducibility and lend credibility to the proposed taxonomy. This paper also considers other key variables of cores including: the morphology of end products, degree of reduction, numbers of striking and removal surfaces, and degree of platform preparation.
