Someone recently posted an article which discussed that issue.
Recent research appeared to show that neanderthal brains (taken from research on the skulls) had a larger chunk of brain addressing the vision center of the brain rather than the higher reasoning centers. Hence it could well be that they simply saw better without being any smarter.
Or it could be as Thomas Sowell often says of the intellectuals of today “It’s not so much that they are ignorant, but rather that they know so much which simply is not true. “

Thanks for the update.
