Here's some controversy for your week: Dr. Watson's comments regarding DNA and racial division of intelligence. Thoughtful article from RS Redstate about it. What are your thoughts on this subject? Are all humans equally intelligent, or do you allow for a bell-curve of intelligence split among races? Does it explain "tribal culture" following a race into western society?
As a zookeeper, I was often asked how intelligent the porcupines were. My answer was always, "They are as intelligent as they need to be to survive. Obviously it works for them." But porcupine society has not changed as radically as human society through history. If we are different, that would explain a lot of clashes of both culture and caste when humans interact as racial groups rather than as individuals.
