>What mechanism does this racial separation take? It's not racial separation. It's all attraction in general. Like attracts like. Hackers tend to like other hackers. Race is simply one factor that affects us. Being aware of this can help you avoid racism. If you don't recognize that your brain tends to prefer people who are similar to you, you're more likely to accidentally discriminate others. >What sort of evidence shows that skin color or other ethnic identifiers in genetics are the thing that causes tribal separation vs them just serving as a simple proxy to more complicated factors? The real extent of its significance is impossible to say, but based on these maps, it's obvious that such separation happens. The lack of any legislation in the US that requires people of certain race to segregate means that it has to be caused by other factors. >What explanations of exigent factors are there... for example why are there black and hispanic republicans, or white members of traditionally "black gangs". How do these less common (but not rare) group membership issues override the claimed genetic selection? The fact that there are black republicans is only evidence that race does not limit people into any certain categories. >What genetic factors explain the fracturing of groups within groups of seemingly genetically similar (at least on a racial/ethinc level) people? Why do brothers and sisters fight? Even if you're from the same family, you're not immune to conflict. Inarguably, family members are on average closer to each other than non-family members. I really doubt race is such a significant factor that it would make us immune to conflict. If you really get down to it, we're all basically identical and we still fight all the time. That's the real stupidity. If you want to learn more, you can start with evolutionary psychology. https://en.wikipedia.org/wiki/Evolutionary_psychology https://en.wikipedia.org/wiki/Evolutionary_psychology We really don't know understand ourselves that well yet, but it's obvious that we discriminate each other. It's important to understand why, so we can become better.
