Answer 2

Explanation:

Undated Acheulean artifacts are abundant across West Africa, attesting to the presence of ancient humans. The emerging chronometric record of the Middle Stone Age (MSA) indicates that core and flake technologies have been present in West Africa since at least the Middle Pleistocene (~780-126 thousand years ago or ka), and that they persisted until the Terminal Pleistocene/Holocene boundary (~12ka)—the youngest examples of such technology anywhere in Africa. The presence of MSA populations in forests remains an open question, however technological differences may correlate with various ecological zones. Later Stone Age (LSA) populations evidence significant technological diversification, including both microlithic and macrolithic traditions.[13]

The presence of Oldowan Earlier Stone Age (ESA) artefacts in West Africa has been confirmed by Michael Omolewa.[14] Acheulean ESA artefacts are well documented across West Africa. None are currently dated. There are few dated Middle Stone Age (MSA) sites; they range from the Middle Pleistocene in northern, open Sahelian zones to the Late Pleistocene in both northern and southern zones of West Africa. The record shows that aceramic and ceramic Later Stone Age (LSA) assemblages in West Africa are found to overlap chronologically, and that changing densities of microlithic industries from the coast to the north are geographically structured. These features may represent social networks or some form of cultural diffusion allied to changing ecological conditions.[13]

Microlithic industries with ceramics became common by the Mid-Holocene, coupled with an apparent intensification of wild food exploitation. Between ~4–3.5ka, these societies gradually transformed into food producers, possibly through contact with northern pastoralists and agriculturalists, as the environment became more arid. However, hunter-gatherers have survived in the more forested parts of West Africa until much later, attesting to the strength of ecological boundaries in this region.
