"I would wager that if an average citizen from Athens of 1000 BC were to appear suddenly among us, he or she would be among the brightest and most intellectually alive of our colleagues," claims Crabtree, who estimates that human beings reached their intellectual peak 2,000 to 6,000 years ago. In theory, that Athenian would have "a good memory, a broad range of ideas, and a clear-sighted view of important issues."
And yet, Ancient Greece is no more. I guess they weren't so smart after all. :laughing:
It seems like a hokey article to me. Humans have just as good a chance of mutating towards intelligence as away from it.
