Who were the West-Central African Bantu (500 BC to 1500 AD)?

West-Central African Bantu is one of the 50 curated source populations in the Classical Antiquity era of Ancient Ancestry, Ancestrify's qpAdm analysis: a group of published genomes pooled as a single reference the model can test your genome against. These are ancient individuals from one archaeological context wherever the record holds them, and present-day genomes standing in where it does not, which the description on this page says.

Does West-Central African Bantu in my result mean they were my ancestors?

No. A source population is a reference the model tests against, never a statement about who your ancestors were. A coefficient on this source means the ancestry those burials represent helps explain your genome to within statistical noise: similar ancestry composition, not descent from those individuals. Ancestrify never claims a population is your ancestor.

What does a West-Central African Bantu percentage in a qpAdm model mean?

qpAdm estimates the mixture proportions that best explain your genome as a combination of the chosen sources, given a fixed set of outgroup (right) populations, and reports a p-value for whether the model is statistically acceptable together with a standard error for every proportion. The percentage is that estimated share, with its uncertainty published beside it.

How do I get a qpAdm model that uses West-Central African Bantu?

Order Ancient Ancestry, Ancestrify's qpAdm analysis (€29.99, one-time), and upload the raw file you already have from a consumer test. Your genome is merged into the AADR reference panel and modelled across both eras; each era's model is built from that era's source populations, so a model for the Classical Antiquity era draws on West-Central African Bantu where it improves the fit.

Can I model West-Central African Bantu ancestry for free first?

Yes. The Ancestrify Lab runs Global25 admixture calculators, a nearest-populations distance tool and an AdmixTools 2 workbench in your browser with no account, and several calculators cover the Classical Antiquity era. Those are G25 fits, not formal qpAdm models. Ancient Ancestry, the paid analysis, is the one with a p-value.

Who they were

Artistic interpretation of the West-Central African Bantu (AI-generated artwork, not documentary evidence)

Period: 500 BC to 1500 AD
Era in the analysis: Classical Antiquity
Region: Gabon, the Congo basin and Angola
Role in the model: Source (left) population, a reference qpAdm tests against

West-Central Africa, the forests, rivers and savannas of Gabon, the Congo basin and Angola, is a heartland of the Bantu-speaking peoples, whose farming villages spread across much of the continent over several thousand years. Between about 500 BC and AD 1500 farmers here cleared the forest edge, worked iron and copper and built the Kingdom of Kongo, one of the largest states of the region, whose capital was Mbanza Kongo in what is now northern Angola. The reference genomes here come mainly from Africans whom the Royal Navy rescued from slave ships between 1840 and 1867 and who were buried on the island of St Helena, together with Kongo people. The St Helena genomes point to origins between northern Angola and Gabon, with ancestry most similar to that of present-day Bantu-speaking populations of West-Central Africa (Sandoval-Velasco et al. 2023), so they stand in for the peoples of this region before European contact.

The Bantu expansion began in western Africa some 6,000 to 4,000 years ago, and the Bantu-speaking peoples received significant gene flow from the local groups they met along the way (Fortes-Lima et al. 2024). This ancestry is carried today across Angola, the Congo and Gabon, and by many people of Brazil, Cuba and the Caribbean whose ancestors were taken from West-Central Africa, the largest source of captives in the Atlantic slave trade (Eltis and Richardson 2010).

In Ancient Ancestry, Ancestrify's qpAdm analysis, West-Central African Bantu is a source in the "Classical Antiquity" era. The report shows its weight with a standard error and a Z-score, so you can see not only how much of the model it carries but how confidently that share is separated from zero, and a model that cannot support it is rejected rather than published. For genomes with African ancestors from the Congo and Angola coast it is the Bantu source to read first, beside the East and Southern Bantu source and the West African sources; the Bantu sources are related, so the model may divide one Bantu signal between them and their weights are best read together.

Y haplogroup E1b1a1 and the mtDNA lineage L2a1f are among those that spread with the Bantu expansions (Sandoval-Velasco et al. 2023). A haplogroup alone is never evidence of a share.

In your report
West-Central Africa, the forests, rivers and savannas of Gabon, the Congo basin and Angola, is a heartland of the Bantu-speaking peoples, whose farming villages spread across much of the continent over several thousand years. Between about 500 BC and AD 1500 farmers here cleared the forest edge, worked iron and copper, wove cloth from raffia palm and built the Kingdom of Kongo, one of the largest states of the region, with its capital at Mbanza Kongo. The reference genomes here come mainly from Africans who were taken from slave ships by the British navy between 1840 and 1867 and buried on the island of St Helena, most of whom came from the coast between northern Angola and Gabon, together with Kongo people. They stand in for the peoples of this region before European contact. This ancestry is carried today across Angola, Congo and Gabon, and by many people of Brazil, Cuba and the Caribbean whose ancestors were taken from West-Central Africa, the largest single source of captives in the Atlantic slave trade.

Where this population sits in the model

Ancient Ancestry, our qpAdm analysis, models your genome once per era. The Classical Antiquity era has 50 curated source populations, and West-Central African Bantu is one of them: every candidate model for that era is a combination of these sources, tested against a fixed set of outgroup populations, and only a model that passes the statistical fit check is published, with a p-value and a standard error on every proportion.

A reference, not a verdict: every population on this page is a source the model tests your genome against, a well-sampled point in ancient genetic space that a mixture of ancestries can be expressed in terms of. A weight on it means your genome is well described as partly resembling those people; it is never a statement that they, specifically, were your ancestors, and a population that fits well is not the only one that could.
