(BISMILLAH) (salam) Here's a really, really very interesting TED talk bu James Flynn about historical development in cognitive ability over the past two centuries and how we are far more "intelligent" than our ancestors a hundred years ago: http://www.ted.com/talks/james_flynn_why_our_iq_levels_are_higher_than_our_grandparents Absolutely phenomenal! He does, however, make one or two uniformed remarks about Islam - possibly because of his ignorance on the subject - but, still, that's not the main subject of his talk and the rest is quite informative.
