The prehistory of Central Africa spans from the earliest human presence in the region until the emergence of the Iron Age in Central Africa. By at least 2,000,000 BP, Central Africa (e.g., Ishango, Democratic Republic of Congo) was occupied by early hominins. West African hunter-gatherers occupied western Central Africa (e.g., Shum Laka) earlier than 32,000 BP, dwelled throughout coastal West Africa by 12,000 BP, and migrated northward between 12,000 BP and 8000 BP as far as Mali, Burkina Faso, and Mauritania. Prehistoric West Africans may have diverged into distinct ancestral groups of modern West Africans and Bantu-speaking peoples in Cameroon, and, subsequently, around 5000 BP, the Bantu-speaking peoples migrated into other parts of Sub-Saharan Africa (e.g., Central African Republic, African Great Lakes, South Africa).
Early Stone Age
By at least 2,000,000 BP, Central Africa (e.g., Ishango, Democratic Republic of Congo) was occupied by early hominins.
Middle Stone Age
In 150,000 BP, Africans (e.g., Central Africans, East Africans) bearing haplogroup L1 diverged.
In 90,000 BP, the oldest fishing-related bone tools (e.g., barbed harpoons) of Africa were developed in Central Africa, particularly, Katanda, Central African Republic.
Between 75,000 BP and 60,000 BP, Africans bearing haplogroup L3 emerged in East Africa and eventually migrated into and became present in modern West Africans, Central Africans, and non-Africans.
Later Stone Age
Earlier than 32,000 BP, or by 30,000 BP, Late Stone Age West African hunter-gatherers were dwelling in the forests of western Central Africa (e.g., earlier than 32,000 BP at de Maret in Shum Laka, 12,000 BP at Mbi Crater). An excessively dry Ogolian period occurred, spanning from 20,000 BP to 12,000 BP. By 15,000 BP, the number of settlements made by Middle Stone Age West Africans decreased as there was an increase in humid conditions, expansion of the West African forest, and increase in the number of settlements made by Late Stone Age West African hunter-gatherers. Macrolith-using late Middle Stone Age peoples (e.g., the possibly archaic human admixed or late-persisting early modern human Iwo Eleru fossils of the late Middle Stone Age), who dwelled in Central Africa, to western Central Africa, to West Africa, were displaced by microlith-using Late Stone Age Africans (e.g., non-archaic human admixed Late Stone Age Shum Laka fossils dated between 7000 BP and 3000 BP) as they migrated from Central Africa, to western Central Africa, into West Africa. Between 16,000 BP and 12,000 BP, Late Stone Age West Africans began dwelling in the eastern and central forested regions (e.g., Ghana, Ivory Coast, Nigeria; between 18,000 BP and 13,000 BP at Temet West and Asokrochona in the southern region of Ghana, 13,050 ± 230 BP at Bingerville in the southern region of Ivory Coast, 11,200 ± 200 BP at Iwo Eleru in Nigeria) of West Africa. By 11,000 BP, the late settlement made by Middle Stone Age West Africans and earliest settlement made by Late Stone Age West African hunter-gatherers emerged in the westernmost region (e.g., Falémé Valley, Senegal) of West Africa. Middle Stone Age West Africans and Late Stone Age West African hunter-gatherers likely did not become admixed with one another and were culturally and ecologically distinct from one another.
Between 25,000 BP and 20,000 BP, hunter-fisher-gatherer peoples in Central Africa (e.g., Ishango, Democratic Republic of Congo) utilized fishing tools and natural resources from nearby water sources, as well as may have engaged in and recorded mathematics (e.g., Ishango bone, which may demonstrate knowledge and use of the duodecimal system, prime numbers, multiplication).
In 19,000 BP, Africans, bearing haplogroup E1b1a-V38, likely traversed across the Sahara, from east to west.
According to Steverding (2020), while not definite: Near the African Great Lakes, schistosomes (e.g., S. mansoni, S. haematobium) underwent evolution. Subsequently, there was an expansion alongside the Nile River. From Egypt, the presence of schistosomes may have expanded, via migratory Yoruba people, into Western Africa. Thereafter, schistosomes may have expanded, via migratory Bantu-speaking peoples, into the rest of Sub-Saharan Africa (e.g., Southern Africa, Central Africa).
While the Niger-Congo migration may have been from West Africa into Kordofan, possibly from Kordofan, Sudan, Niger-Congo speakers (e.g., Mande), accompanied by undomesticated helmeted guineafowls, may have traversed into West Africa, domesticated the helmeted guineafowls by 3000 BCE, and via the Bantu expansion, traversed into other parts of Sub-Saharan Africa (e.g., Central Africa, East Africa, Southern Africa).
