anymore, and the slight edge that is may afford you the 1 breeding offspring
more on average in your whole life - which may be well enough. It is not likely
to help you on a regular base if something much bigger and stronger pounces
upon you. You either have good karma, or don't.
Once an innovation gets fixed and is apomorphized, all bets are off. But
instant gratification through evolutionary innovation... no. With noxious
chemicals or eyecolour maybe, but not with complex morphological/behavioral
