Four decades have passed since Harlan and Stemler ( 1976 ) proposed the eastern Sahelian zone as the most likely center of Sorghum bicolor domestication. Recently, new data on seed impressions on Butana Group pottery, from the fourth millennium BC in the southern Atbai region of the far eastern Sahelian Belt in Africa, show evidence for cultivation activities of sorghum displaying some domestication traits. Pennisetum glaucum may have been undergoing domestication shortly thereafter in the western Sahel, as finds of fully domesticated pearl millet are present in southeastern Mali by the second half of the third millennium BC, and present in eastern Sudan by the early second millennium BC. The dispersal of the latter to India took less than 1000 years according to present data. Here, we review the middle Holocene Sudanese archaeological data for the first time, to situate the origins and spread of these two native summer rainfall cereals in what is proposed to be their eastern Sahelian Sudan gateway to the Red Sea and the Indian Ocean trade.

This paper presents new excavation data and new radiometric dates for Jebel Moya, south-central Sudan. These data suggest revisions to previous chronological understandings of the site. New excavations, initiated in 2017, show a longer, more continuous occupation of the site than has been previously recognised. Archaeozoological and archaeobotanical analyses provide evidence for domesticated taxa. Archaeobotanical evidence is dominated by domesticated sorghum (Sorghum bicolor), radiocarbon dated to c. 2550-2210 BC. Faunal remains include cattle and goat/sheep. A late third-millennium BC date on the human skeleton excavated in the 2017 season also shows that mortuary activity began early in the site's history, contemporary with domesticated faunal and botanical remains. These initial results indicate the long-term association of the site with pastoralism and agriculture and with environmental change. Jebel Moya's continued potential to serve as a chronological and cultural reference point for future studies in south-central Sudan and the eastern Sahel is reinforced.

This paper proposes a new chronology for the burial complex at Jebel Moya, south-central Sudan. It reassesses the body of evidence from Sir Henry Wellcome's original 1911–1914 excavations in order to place the site within a firm chronological framework by: (a) applying an attribute-based approach to discern discrete pottery assemblages; and (b) applying initial OSL dates to facilitate the reliable dating of this site for the first time. Jebel Moya is re-interpreted as a burial complex situated on the southern periphery of the late Meroitic state, and its potential to serve as a chronological and cultural reference point for future studies in south-central and southern Sudan is outlined.

Nearly four decades have passed since an independent North African centre for cattle domestication was first proposed in 1980, based on the Combined Prehistoric Expedition's work in the Nabta Playa-Bir Kiseiba region of southern Egypt, and the initial rigorous debates between Andrew B. Smith and Fred Wendorf, Romuald Schild and Achilles Gautier. More recently, geneticists have entered the fray with determinations on the spread of haplotypes, and the timing thereof, that extend the scope and increase the complexity of the debate. Here, a new look at the botanical data and a re-analysis of the geology of Bir Kiseiba-Nabta Playa rejects the ecological foundations of the early African domestication model, while a detailed examination of the published osteological and radiometric data from the same area reveals a more nuanced picture than has been recognised to date. These results are placed into context by a wider review of the genetic and other archaeological evidence from the Western Desert of Northeast Africa, where no other cattle remains designated as domesticated have been found. It is concluded that (a) Bos remains from the early Holocene at Nabta Playa-Bir Kiseiba were those of hunted aurochs; (b) domesticated caprines were likely present in Northeast Africa before domesticated cattle; and (c) the domesticated cattle spreading across Northeast and northern Africa, including Nabta Playa-Bir Kiseiba, from the late seventh millennium BC or early sixth millennium BC onwards were descendants of Bos taurus domesticated in the Middle Euphrates area of the Middle East.
