Not all populations archieved a civilization worth of note, Some did, and the ones who did correlate whit the least "brown/dark skinned" ones, its as simple as that, its the correlation of stability and social cues that give to their descendants, the racial aspect of it its only the visible part because culture, lenguage is non tangible
For example, I consider east asians to be capable of civilization, even tho they are way more into the collectivist mindset.
In the americas, the mayans and aztecas (even tho barbarian due to their rituals, who correlated more to the ones 1100 ac times, were too backwards in alot of ways
and so on
