Thanks for the article; it contains much truth. I read Sir Arthur Keith years ago, and his great contribution was to show that human evolution is not so much evolution of individuals, but of human groups (tribes, nations, races), which necessarily implies cooperation. I don't see this as contradicting what I said about competence, though. We cannot be led -- in any field -- by average Walmart shoppers, nor will we be. Any pretense that we are (such as "democacy") is just a cover for evil and knavery behind the scenes.
