Watch a TV documentary set in an African game park and the response of prey animals like a herd of gazelle to the presence of predators seems unbelievably strange from the human viewpoint. If a lioness is lying at the edge of the herd, watching intently, picking out a target, this fearsome predator is likely only to be eyed briefly, if nervously, but its potential victims before the gazelle return to cropping the coarse grass. We would be thinking, "I've got a problem here. That lioness could hurt me or even kill me. I think I'll sneak away, just in case. Or at least I'll make sure there's a fatter, slower gazelle between me and the lioness." But this ability to project into the future, to be aware of potential circumstances and analyze consequences, isn't present in the gazelle. It is only when the attack commences that a flight response is triggered. ~ Page 9
