To my 5 year old knowledge I thought Neanderthals were different species but for us to have part of their dna that means they got jiggy together and created fertile off spring with Homo sapiens but when a donkey and a horse do it they make infertile offspring? Are we not like actual separate species?
In: Biology
There were many different “breeds” of humans at one time. Only one species tho. So they could have crossbred. Some likely did like neanderthals did. Some maybe did not and went extinct without leaving rests of their dna in ours.
