Earliest Herders of the Central Sahara (Tadrart Acacus Mountains, Libya): A Punctuated Model for the Emergence of Pastoralism in Africa

Abstract

This paper focuses on a reassessment of the emergence of herding in Africa seen from the Tadrart Acacus and neighbouring regions in the Libyan central Sahara. The paper examines whether the presence of wild animals in the Early Holocene ‘green’ Sahara could have represented a ‘disease challenge’ to the spread of domestic livestock, as proposed for sub-Saharan Africa. Analysis of the zooarchaeological record and Saharan rock art highlights this potential threat also in North Africa, where it has hitherto been disregarded. Old and new data from the study area in SW Libya, with a focus on Takarkori rock shelter, highlight the presence of herding activity at a very early stage. Direct dating on bones of sheep/goat and cattle secures this chronology, providing evidence of a rapid ingression of small groups of herders who crossed Africa’s north-eastern quadrant around ~ 8300 years cal BP. This rapidity defies the ‘disease challenge’ hypothesis and suggests alternative scenarios. In the central Sahara, the cultural complexity of local Early Holocene hunter-gatherers and their delayed return system of resource exploitation could have facilitated the incorporation of new practices, including the herding of small numbers of domestic animals. The societal implications of the transition from hunting and gathering to herding are archaeologically better visible in the funerary record and in rock art. By contrast, both material culture and the subsistence basis seem to demonstrate continuity with the former foraging groups’ phase. Taken together, the Saharan evidence suggests a punctuated process of acculturation for the inception of food production in North Africa.
