Given the amount of scientific and technological progress the human race had made thanks to people on the spectrum it seems fairly obvious to suspect there would be selection pressure for autistically-minded individuals. I'm sure there are factors that make someone more likely to present as autistic though. I think there is some evidence to suggest that prenatal hormone levels (and specifically testosterone) have some influence, and I believe some researchers have even gone so far to say that the autistic brain is wired like the male brain but to an extreme. It may just be that older woman are more likely to have suboptimal hormone levels which makes these kind of developmental extremes more likely.
