  While there is sufficient circumstantial evidence to associate the Bushmen (as well as their cultural predecessors) with the rock-art of South and perhaps East Africa, these people cannot easily be connected with the petroglyphs of North Africa. There is, however, a school of thought which maintains that during the Late Stone Age periods a Bushman-like hunting culture extended from southern Europe to southern Africa. But in view of the fact that many of the North African rock-paintings and rock-engravings belong definitely to later periods-pictures of domesticated camels can hardly antedate the introduction of camels into North Africa around 200 B.C.it must be assumed that the Hamites who have inhabited this region since 5000 B.C., if not before, must be connected with the rock-art of these northern zones.
