Yes, but.... The trouble with evolutionary explanations of human psychology is that they are "just so stories". Actual tests of these hypotheses are extremely difficult. Sometimes you can get somewhere with experiments on other mammals, but for the most part its high piles of speculation. The little story about the possibly autistic reindeer herdsman is a case in point. Nice anecdote, but the plural of anecdote is not evidence. Then you mix in speculation about primitive tribes with considerations of supernormal stimulii and possible actual disease or genetic damage, and you wind up with exactly the same morass that the article complains about in current psychiatry. And even when you have a tested theory it provides very little guidance about how to help afflicted individuals live in modern society.
