Integrating Human-Animal Relationships into New Data on Aterian Complexity: a Paradigm Shift for the North African Middle Stone Age

Abstract

In the last decade, research conducted in North Africa, particularly in northwestern Africa, has shed light on the key role that the region has played in improving our understanding of human evolution. Specifically, (1) the increased number of direct dates obtained with new methods has pushed back the age of the Aterian (~ 150,000 to 40,000 BP); (2) analyses of Aterian lithic assemblages have placed them within the range of variation of the Middle Stone Age; (3) analyses of associated human remains suggest that the makers of the Aterian are within the range of variation common among early modern human and present affinities with contemporary remains from the Levant (Qafzeh, Skhul); (4) zones of settlement, such as those in the present-day Sahara and coastal areas, and even the composition and demography of populations could have been influenced by specific climatic changes of the Late Pleistocene; and (5) the presence of blocks of pigment showing use-wear facets on their surfaces, the presence of pigments on artifacts, as well as osseous industry and earliest ornaments suggest complex behaviors among these populations. In this renewed approach to the Aterian, data from faunal analyses provide information on human-carnivore competition and the subsistence practices of hunter-gatherer groups. Taphonomic and zooarchaeological analyses suggest that humans were not the only large predators occupying caves, and that the hunter-gatherers of the Middle Stone Age exploited a wide range of environments, consuming terrestrial and coastal resources alike. Interdisciplinary confrontations highlight the apparent complexity of socioeconomic organization and the strategies of high levels of mobility that characterized Aterian groups.
