Throughout history many African peoples have pursued traditional ways of life unchanged since they were first depicted in ancient cave-paintings: the passage of the centuries seems to have had little or no impact. In the Kalahari desert of southwestern Africa, the San peoples still hunt game with bows and arrows as their forefathers have always done, while in many parts of sub-Saharan Africa villagers continue to use digging sticks to plant their crops. Similarly, the staple crops cultivated by these farmers, including millet, sorghum and yams, have remained unchanged for centuries.
