What would the average skin tone and facial features look like after 300 years if every partner relationship was interracial until there were no other ethnicities? Just a hodgepodge of DNA. What would the average human look like having a little bit of everything in them?
I just think the idea is neat is all.
Do we have any current examples of a human with more than 4 or so distinct racial backgrounds? Like white and black grandparents with a mixed child with another Asian and middle eastern grandparents also having a mixed child. Then those children having a kid of their own.
At a guess, anywhere around the Mediterranean would likely have people with this profile.
Pretty much everyone.
Race is a human social construct, and in terms of genetic histories only vaguely useful. While it is a useful tool, for say, comparing ancient remains… despite what ancestry.com tells you identify race from genetics of individuals is almost impossible and really stupid.
But they want to make money, and selling your kits and then selling your admixture dna to the highest bidder is big business
