The third and final phase of Stone Age technology in sub-Saharan Africa, dating from about 30,000+ years ago until historical times in some places. There was much art and personal decoration, evidence of burials, and in assemblages some microlithic stone tools. Pottery and stone bowls appear during the last three millennia as the lifeways changed to herding from nomadic hunting and gathering. The large number of distinctive Later Stone Age industries that emerged reflect increasing specialization as hunter-gatherers exploited different environments, often moving seasonally between them, and developed different subsistence strategies. As in many parts of the world, changes in technology seem to mark a shift to the consumption of smaller game, fish, invertebrates, and plants. Later Stone Age peoples used bows and arrows and a variety of snares and traps for hunting, as well as grindstones and digging sticks for gathering plant food; with hooks, barbed spears, and wicker baskets they also were able to catch fish and thus exploit rivers, lakeshores, and seacoasts more effectively. The appearance of cave art, careful burials, and ostrich eggshell beads for adornments suggests more sophisticated behavior and new patterns of culture. These developments apparently are associated with the emergence between 20,000 and 15,000 BC of the earliest of the historically recognizable populations of southern Africa: the Pygmy, San, and Khoi peoples, who were probably genetically related to the ancient population that had evolved in the African subcontinent.
