If we pass from the southwestern United States to South Africa, a corresponding situation confronts us. The same area at one time formed the habitat of the Bushmen and the Hottentots; yet, their mode of life varies fundamentally. The Bushmen are essentially hunters and seed-collectors, while the Hottentots are an eminently pastoral people. Caves and crude windbreaks form the Bushman’s original dwellings, while the Hottentots have mat-covered portable beehive-shaped huts. The Bushman’s principal weapons are bow and arrow, with the Hottentot these implements are of secondary importance as compared with the spear. It is true that not only material objects but even myths and folktales are shared by both tribes, but in many instances of this sort we have clearly a case not of independent response to the same external conditions but rather the result of borrowing. Thus, some of the traits common to Hottentot and Bushman, for example, a fair number of mythic episodes, occur likewise among the Bantu Negroes inhabiting contiguous but geographically different territory. One of the most interesting traits of ancient Bushman culture is the life-like representation of animals on rocks and the walls of caves. Oddly enough, these engravings and mural paintings, which distinguish the Bushmen from their South African neighbors, have their nearest parallels in the Spanish cave-paintings of Palæolithic Europe. The picturing of the mammoth and reindeer by these old South European artists clearly proves that they belonged to a glacial epoch, during which geographical conditions could hardly have resembled those of the Kalahari desert.[2] One other illustration from the same general region of the Dark Continent is suggestive. The Ovambo and Herero, neighbors though they are, differ in the essential features of their economic life. While the Ovambo depend only to a very limited extent on their herds, deriving their sustenance mainly from the cultivation of millet and other plants, the Herero are the only non-agricultural Bantu people, being predominantly pastoral.
