Elephants, if you just inserted yourself into human life the way cows did, you could have used your power and intelligence to form secret elephant societies, conspiring against the humans. And then you could have risen up and destroyed us and made an awesome elephant world with elephant cars and elephant planes. It would have been so great, but no. You gotta be pregnant for twenty-two months and then have just one kid. It's so annoying. Best wishes, John Green. Right, but back to the agricultural revolution and why it occurred.
