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.
The whole race theory has been debunked over a century ago. You also have genetic difference in foot shape, blood type and many more, and a race system build on that would be as wrong as one based on skin colour
Oh I’m not particularly informed on any of this because I don’t really care tbh, but I though race was where you (and your ancestors) are from as opposed to skin colour?
Some people use “race” to mean that, but the word you’d be looking for is ethnicity.
