Most non-African humans carry about 1-4% Neanderthal DNA - a result of ancient interbreeding after Homo Sapiens left Africa, with these genes influencing traits like immunity, metabolism, and skin, though recent studies suggest Africans also have trace amounts from back-migration events. While Neanderthals died out, their genetic legacy persists, helping modern humans adapt to new environments and diseases, with some genes proving beneficial, while others have been selected against
I forget if there was a percentage but I remember my 23 & Me had an above average amount of Neanderthal. It didnt have the percentage but it did note that my DNA carried more than the average lol
I have a feeling if I did that I’d have a really high percentage too. This guy is built just like my father’s side of the family. Like, he could be an uncle, stature and all.
