> 200 years later, with a population that's multiplied several magnitudes over - would you expect to still see a completely equal people? I wouldn't

I would. South Koreans are 2-3 inches taller than North Koreans, plus a miriad of other biological differences, in a relatively short span of time. This is for the same ethnicity, yet alone race.

For me, that alone is proof we are much more similar than we think, and environmental factors, which your hypothetical scenario accounts for perfectly, has a much greater impact on us compared to genetics.

Which is why, for perfectly randomly selected humans raised identically for 200 years, I would not expect significant differences.
