They Tested Human Genes Of Living People
This might have taken place a long time before modern humans decided to leave Africa. Rogers called it “the earliest known interbreeding between ancient human populations and their expansion out of Africa.” Rogers’ team’s version was that the mixing probably happened inside and outside of Africa. However, not everyone agrees with their team’s study. Rogers and his team were still confident about their research because they had many backup explanations about it. They tested the human genes of living people, and evidence of interbreeding would be found in their genes.
Intermixing Of Species
Another set of researchers from the University of California Los Angeles (U.C.L.A.) did similar research work on D.N.A. extracted from people of West Africa. They compared the genomes of West Africans with the genomes of Neanderthals and Denisovans. The study would show that if both genomes showed differences or variations, this should probably be a possible intermixing that happened even before the human ancestors of modern humans ever decided to leave Africa. Many populations have been discovered to be involved in the intermixing of species.
