Khoisan

Khoisan (also spelled Khoesaan, Khoesan or Khoe–San) is a unifying name for two ethnic groups of Southern Africa, who share physical and putative linguistic characteristics distinct from the Bantu majority of the region. Culturally, the Khoisan are divided into the foraging San and the pastoral Khoi. The San include the original inhabitants of Southern Africa before the southward Bantu migrations from Central and East Africa reached their region, which led to Bantu farmers replacing the Khoi and San as the predominant population. Khoi pastoralists apparently arrived in Southern Africa shortly before the Bantu. Over time, some Khoi abandoned pastoralism and adopted the hunter-gatherer economy of the San, likely due to a drying climate, and are now considered San. Similarly, the Bantu Damara later abandoned agriculture and adopted the Khoi economy. Large Khoisan populations remain in several arid areas in the region, notably in the Kalahari Desert.
