So this explains Glenn Beck and Rush Limbaugh:
Today’s human brain is 10% smaller than that of our Cro-Magnon ancestors, but scientists are divided on whether that means we are getting smarter or dumber. Some say it does represent a dumbing down, but that our increasingly complex society means individuals don’t need as much intelligence to survive and reproduce. Others think it’s a sign of domestication and lower aggression, pointing to cases of shrinking brain mass among some species as they become less violent, reports NPR. “Another way to say that is an increase in tolerance,” said a Duke anthropologist.
Increase in tolerance?
Nope. That doesn’t explain it..
