Do Africans have Neanderthal DNA?
According to a later study by Chen et al. (2020), Africans (specifically, the 1000 Genomes African populations) also have Neanderthal admixture, with this Neanderthal admixture in African individuals accounting for 17 megabases, which is 0.
Who are the descendants of Africa?
African diaspora populations include but are not limited to: African Americans, Afro-Caribbeans, Afro-Latin Americans, Black Canadians – descendants of enslaved West Africans brought to the United States, the Caribbean, and South America during the Atlantic slave trade.
