When you look at the relationship between two entire species like rabbits
and wolves it begins to look even more like cooperation where the rabbits
cooperate by providing food for the wolves and the wolves cooperate by NOT
WIPING OUT THE ENTIRE RABBIT POPULATION!
Now, let's imagine that wolves learned to eat grass and started to enjoy it.
What they do then is simply catch and eat all rabbits -- to eliminate
competition for grass. Of course, some rabbits may be real quick-pawed
(hint, hint).
It's called balance.
It is bound to shift.
