Grinding stone features from the Pastoral Neolithic at

The initial spread of food production in eastern Africa is associated with livestock herding during the Pastoral Neolithic. Recent excavation at Luxmanda, Tanzania, a site dating to c. 3000 BP, revealed circular installations of lower grinding stones and numerous handstones.This discovery, unprecedented for this era, challenges previous ideas about pastoralist mobility and subsistence.
