African cereal domestication underway across sahel zone

Cultivated bulrush and finger millet had reached India by the middle of the second millennium BC, allowing inference that domestication of African millets was taking place not later than the third millennium BC over a wide area of the sahel zone of Africa. The earliest archaeological evidence for bulrush millet comes from the twelfth century BC in southern Mauritania. The zone of African cereal domestication coincides precisely with the zone of the wavy-line pottery and bone-harpoon tradition.
