Homo sapiens didn't evolve from Denisovans and Neanderthals. All are branches of human and existed at the same time and interbred.* Homo sapiens survived while Neanderthals and Denisovans became extinct. The majority of the ancestry of living humans, Homo sapiens, was originally from Africa. Europeans have some Neanderthal ancestry (like 2%) due to interbreeding with Neanderthals, but the vast majority of European DNA is from Africa. Sub-Saharan Africans have less Neanderthal ancestry than Europeans and more Homo sapiens ancestry. * https://en.m.wikipedia.org/wiki/Interbreeding_between_archaic_and_modern_humans https://en.m.wikipedia.org/wiki/Interbreeding_between_archai...
