What is Your Flight Distance?

Richard Dawkins: the truth dogs reveal about evolution:

We are puzzled, because our own risk aversion (or that of our safari guide) keeps us firmly inside the Land Rover even though we have no reason to think there is a lion within miles. This is because we have nothing to set against our fear. We are going to get our square meals back at the safari lodge. Our wild ancestors would have had much more sympathy with the risk-taking zebras. Like the zebras, they had to balance the risk of being eaten against the risk of not eating. Sure, the lion might attack; but, depending on the size of your troop, the odds were that it would catch another member of it rather than you. And if you never ventured on to the feeding grounds, or down to the waterhole, you’d die anyway, of hunger or thirst. It is a lesson in economic trade-offs.

The bottom line of that digression is that the wild wolf, like any other animal, will have an optimal flight distance, nicely poised — and potentially flexible — between too bold and too flighty.
