okay let me know if this sounds unhinged to you.
Genealogical ancestry leaves it’s marks on the genome of populations. We can see the impact of a single male (Genghas Khan) has on the genome of about a billion present day people. We can see the effect of genealogical ancestry (and limited selection in breeding) on the genome of people with certain diseases. Let’s take the case of just one Neanderthal/Sapian mating. It made it through to billions of people today. So do you and I have a Neanderthal in our genealogy - unquestionaly yes. Has it impact our genomes - all unquestionally yes. Does an African have a Neanderthal in his genome - unquestionably no. Has Neanderthal impact his genome - unquestionally no.
Here is something that you are not going to like but it is very true. Studying genealogy and making claims about genealogy is inherently racist. You can get around it. Whether we are taking what makes us human or not. Is these people over here are better than those people over there. Take Meso American Indians. They are going to scream “racist” as you soon as you even talk about a Middle eastern Adam as being part of their genealogy. They have been through this before and the results we not good for them. So I really caution you about exploring this avenue of research as any findings scientifically or theologically is going to be instantly labeled Racist.
