Archaeology is revealing evidence that strongly suggests that the evolution of humans began in Africa. Virtually every stage of our development—stretching back over 5 million years—can be traced in the African record. Almost throughout this vast span of prehistory our ancestors lived in mobile groups engaged in scavenging, gathering and hunting.

From about the 10th millennium BC onwards, conditions in large parts of Africa were wetter than they are today, and human settlements began to spring up by lakes and rivers, from the Rift valley and Sudanese Nile valley in the east, across what are now the central and southern Saharan regions, to the Senegal River in the west. These earliest African settlements were based on fishing and were characterized by certain shared aspects of material culture, most notably barbed, bone harpoon heads. Such similarities between the disparate settlements have led to the view that these communities were part of one cultural complex. However, there is considerable local variation in associated stone-tool industries, and it may therefore be more accurate to consider the appearance of these sedentary hunting-gathering-fishing communities as the result of a broadly contemporary, but independent, adaptation of different groups of people to the changing environment.

It was this ability to adapt to changing circumstances that led to the gradual transition to food production, that is, the cultivation of domesticated plants and herding of domesticated animals. It must be stressed that our current understanding of African food production is far from comprehensive. However, the view that food-producing techniques spread from the Fertile Crescent via the Nile valley to the rest of Africa is no longer tenable as far as plant cultivation (with the exception of wheat and barley) is concerned, and it may not be so for cattle domestication. From the 7th millennium BC onwards there is evidence of cattle-herding in present-day Algeria and the Egyptian Western Desert at Nabta Playa, which may be indicative of local domestication. At about the same time barley, wheat and domestic small stock, such as sheep and goats, were introduced from the Near East into the Nile delta. In central and southern Sahara early food production involved a move from fishing to livestock herding. The domestication of plants in these regions seems to be associated with progressive dessication after about the 5th millennium BC. As water and grazing land disappeared in the emerging desert, cattle-herding communities dispersed. These climatic and demographic factors initiated, or perhaps accelerated, the independent development of tropical agriculture.

However, it was only in the Nile valley that the advantages of food production led to state formation before about the 1st millennium BC. This is seen most spectacularly in the rise of dynastic Egypt at the end of the 4th millennium; but as early as about 2400 BC there is evidence of a substantial town at Kerma, near the third cataract, which includes fortifications, facilities for copper-smelting and eight large mound graves. Because of the many Egyptian artefacts recovered from the site, Kerma was once thought to have been an Egyptian colony. But there is plentiful evidence to support the view that it was a Nubian site and that the indigenous people had a prolonged, primarily commercial, contact with Egypt. Kerma reached a political and cultural peak during Egypt’s Second Intermediate Period (c. 1720–1550 BC) but failed to survive the militaristic imperialism of the New Kingdom. The kingdom of Napata, which succeeded Kerma, did not emerge until about 900 BC.
