Dispersals and genetic adaptation of Bantu-speaking populations in Africa and North America Etienne Patin cs 2017 Science 356:543-6 doi 10.1126/science.aal1988
Bantu languages are spoken by c 310 M Africans, yet the genetic history of Bantu-speaking populations remains largely unexplored. We generated genomic data for 1318 individuals from 35 populations in W-C.Africa (where Bantu languages originated): - early Bantu speakers first moved south-ward, through the equatorial rain-forest, - then spread toward E- & S-Africa. - genetic adaptation of Bantu speakers was facilitated by admixture with local populations (esp. the HLA & LCT loci). We identified a major contribution of W-C.African Bantu speakers to the ancestry of African Americans, whose genomes present no strong signals of natural selection. Together, these results highlight the contribution of Bantu-speaking peoples to the complex genetic history of Africans & African Americans. ___
On the history of Bantu speakers
Africans are underrepresented in many surveys of genetic diversity, this hinders our ability to study human evolution & the health of modern populations. Patin cs examined the genetic diversity of Bantu speakers (1/3 of sub-Saharan Africans). They then modeled the timing of migration & admixture during the Bantu expansion. This revealed adaptive introgression of genes that likely originated in other African populations (e.g. specific immune-related genes). Applying this information to African Americans suggests that gene-flow from Africa into the Americas was more complex than previously thought. <http://science.sciencemag.org/lookup/doi/10.1126/science.aal1988>

There is no such thing as Bantu people because Bantu means people. LOL!

In non-Bantu languages, obviously, bantu does not mean people.
In Bantu languages, bantu means people, muntu means person.
People who speak Bantu languages are called by outsiders/Europeans "Bantu" as a conventional descriptive name for the group. Zulus are Bantu-speakers (with San borrowings), Ki-Swahili is a Bantu language (with Arabic borrowings).

^^ The word "bantu" doesn't necessarily exist in all the languages in the "bantu" phylum.
