Culture and convergence: The curious case of the nubian complex

Abstract

‘Nubian Levallois’ lithic technology has been found from South Africa to India, it occurs sporadically over a period of more than two hundred thousand years, and it appears to be associated with at least two hominin species. Despite this, proponents of the ‘Nubian Complex’ argue that this technocomplex—often, but not exclusively, defined by the presence of Nubian Levallois technology—offers a strong culture historical signal. This argument claims that the Nubian Complex is an originally Northeast African entity, dating to Marine Isotope Stage 5, and that by tracing the distribution of Nubian Levallois technology it is possible to trace the spread of Homo sapiens from Northeast Africa. In light of these bold claims, it is important to test the reality and usefulness of the Nubian Complex idea. In this paper I review the history of the Nubian Complex, evaluate sites assigned to it, and consider the characteristics and significance of Nubian Levallois technology. This review suggests that the original reasons for defining the Nubian Complex were flawed, definitions of it are overly-variable and inconsistent, and that the concept is driving misleading models that are actively harming interpretations of the record. It should therefore be abandoned. Perhaps the most telling criticism of the Nubian Complex is that even its proponents do not agree on which sites should be included (e.g. Bir Tarfawi). I explore the possibility that Nubian Levallois technology—which should be disentangled from the culture-historical concept of the ‘Nubian Complex’—represents a case of convergent evolution and identify avenues for future research. This reorientation facilitates insights into the behavioral significance of Nubian Levallois technology, in terms of factors such as standardization and mobility strategies.
