DNA data was analysed from four children—two of whom were buried approximately 8,000 years ago and two 3,000 years ago—from Shum Laka (Cameroon), one of the earliest known archaeological sites within the probable homeland of the Bantu language group.
One individual carried the deeply divergent Y chromosome haplogroup A00, which today is found almost exclusively in the same region.
However, the genome-wide ancestry profiles of all four individuals are most similar to those of present-day hunter-gatherers from western Central Africa, which implies that populations in western Cameroon today—as well as speakers of Bantu languages from across the continent—are not descended substantially from the population represented by these four people.
Our analyses show that the four sampled children from Shum Laka can be modeled as admixed with ∼35% ancestry related to West-Central African hunter-gatherers and ∼65% from a basal West African-related source, or alternatively as a mixture of hunter-gatherer-related Shum Laka Cameroon DNA
Our analyses show that the four sampled children from Shum Laka can be modeled as admixed with ∼35% ancestry related to West-Central African hunter-gatherers and ∼65% from a basal West African-related source, or alternatively as a mixture of hunter-gatherer-related ancestry plus two additional components, one from inside the clade of present-day West Africans and one splitting between East and West Africans.
