I would be very surprised if high intelligence was anything other than the extreme edge of a normal distribution of the human population. For it to be anything other than this it would require people of high intelligence to be a sub-population that did not breed with the rest of humanity.

'would require people of high intelligence to be a sub-population that did not breed with the rest of humanity' - which is increasingly what is happening with people of high ability & potential income of both sexes attending the same universities and mating. This polarization has been documented.

This polarization has been documented.

And seems to produce a higher incidence of autism too, if the anecdotes are to be believed...

That has more to do with parental age than anything else.
