Mostly "not," but I'll play with the ideas anyway:
The difference in intellect between individuals is obvious; that doesn't necessarily have anything to do with evolution though, does it?
No, not necessarily. Bright people tend to have bright kids. I can't evaluate the "nature vs. nurture" issue. This is more a matter of genetics than evolution, except to the extent that intelligence (at least partly a product of genetics) is a survival factor for the species. It no longer is, but in the very early days of our species, presumably the worst of the idiots didn't survive very long. Alas, their genes still pop up.
The view of superior vs. inferior races has a certain dubious intellectual importance, perhaps it is fodder for the social sciences and selling books like The Bell Curve. It's not surprising, though, given the penchant for collectivist ideology of the last century-and-a-half.
It's meaningless to me when someone claims that "group X is statistically smarter than group Y." The only value to books like Bell Curve might be that if group X is statistically doing worse in school, for example, than group Y, it could be useful to know that it's possibly not group Y's fault. But this is only significant in the context of government programs, etc. Without "great society" meddling, no one would need to know such statistics.
More interesting to me is the question of cultures; are some superior to others? Why did the Egyptian culture last for thirty centuries and the Roman Empire last so long and why did they become "extinct" (to borrow a term)?
There are definitely superior cultures. I won't even bother to argue with anyone who doesn't see this. Egypt is an interesting case. They lasted a very long time, and not because they respected "life, liberty, and property." It's been suggested that the combination of a military dictatorship, reinforced by a state-sponsored religion, plus a virtual monopoly over a scarce and vital resource (the Nile) gave them what they needed to survive so long. And Rome lasted only as long as they had military superiority.
Ben Franklin gave us about two hundred years from the adoption of the Constitution. American culture is dissolving in the cheap acid of multiculturalism which is really more of an idea ABOUT culture, rather than a culture in itself.
Don't get me started on this. Too depressing.
I believe that all tradition, culture and religion seems to suffer under the omnivorous tyranny of ideology which has come to dominate all dialogue since Descartes.
I suspect it started long before that. Too big a topic to get into. Wait for a philosophy thread to come along on this issue.
I have come to recognize ideology as Original Sin writ large across the pages of history.
Interesting notion. Any code of conduct that is not firmly grounded in reality can be a source of amazing problems.
Survival implies nothing except adequacy. Superior and inferiority mean nothing in evolution unless there is differential selection going on.
