How did I talk about the outside appearance?You really think the phenotypic variation in the outside appearance of humans requires 2% of the genome?
Come again? Considering "all the wars young men have fought in over the millennia", how low would you have expected this figure to be? About 60% of all men who have ever lived does not have descendants living today. That significantly more than half of all men lose out in the evolutionary game is quite noteworthy.I don't know where you get those figures but if true 40% is pretty damn high considering all the wars young men have fought in over the millennia.
Anyway, I got the numbers from a talk by Roy F. Baumeister, of the Florida State University. He himself referred to "recent research with DNA analysis". I'll see if I can find a better citation.
By noting that everyone in the US is told to "go to college and get a good job", and the fact that intelligence follows a Gaussian distribution in the populace. Such a distribution means that there are a few stupid, a few smart, and many average intelligent people. However, the Gaussian curve is different for men and women, in that men have a greater variance than women. So we do in fact have more stupid men and more smarter men than women, and also more of the averagely intelligent people are women.I believe this is semi-true but how to explain why these days (at least in the US) females seem to be much more motivated than males to do well in school, get into a good college, etc.? (I can't objectively quantify this but it seems to be the case)
Since intelligence is more and more needed the higher in the educational system one gets, it is logical to expect the dumbest people to fall off first. And since a majority of stupid people are men, they fall out and the result is that by college entrance there are more women than men. However, as one goes further up, the stupidest people still continue to fall out, and after getting to and passing the average intelligence that means more and more women fall out relative to men. So at the "top", there is a greater amount of men than women. Though remember that all of the people at the top are very intelligent. Just as the people who fell off early are less intelligent, no matter whether they're men or women.
+Necessary disclaimer about this being "in general", "statistically speaking", etc. You can always find exceptions, but this is the more "normal" case as it is.
