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.
I don’t think 300 years would be enough to completely homogenize all races even if done intentionally.
Even so given the appropriate amount of time, where do you think we might end up?
