“Our ancestors could make two kinds of mistakes: (1) thinking there was a tiger in the bushes when there wasn’t one, and (2) thinking there was no tiger in the bushes when there actually was one. The cost of the first mistake was needless anxiety, while the cost of the second one was death. Consequently, we evolved to make the first mistake a thousand times to avoid making the second mistake even once.” – Dr. Rick Hanson, Hardwiring Happiness

“Adaptations are structures or behaviors that allow efficient use of the environment. So it’s not hard to assume that at least a few monkeys in the pack adapted to be on the lookout for jaguars. Some may even have become preoccupied with this responsibility. The packs of monkeys who had at least one member who adapted to become watchful and vigilant for jaguar attacks? Survived, and propagated. The packs of monkeys who did not adapt? Jaguar chow.” – Me, August 2013
