“In evolutionary terms, that means we asked for it.”

“Considering that we live in an era of evolutionary everything---evolutionary biology, evolutionary medicine, evolutionary ecology, evolutionary psychology, evolutionary economics, evolutionary computing---it was surprising how rarely people thought in evolutionary terms. It was a human blind spot. We look at the world around us as a snapshot when it was really a movie, constantly changing.”

“The alternative to thinking in evolutionary terms is not to think at all.”

“We have become, by the power of a glorious evolutionary accident called intelligence, the stewards of life's continuity on earth. We did not ask for this role, but we cannot abjure it. We may not be suited to it, but here we are.”

“People talk about human intelligence as the greatest adaptation in the history of the planet. It is an amazing and marvelous thing, but in evolutionary terms, it is as likely to do us in as to help us along.”

“In terms of evolutionary history, it was only yesterday that men learned to walk around on two legs and get in trouble thinking complicated thoughts. So don't worry, you'll burn out.”
