Zero-sum is only a simplification, the world can get richer or poorer and I don't think is a zero-sum game. Evolution is not related to zero-sum games. Perhaps the post is about learning to cooperate is better that thinking life is a zero-sum game.

" Evolution is not related to zero-sum games"

Of course it is. If the deer does not run faster, the cheetah will have him/her for dinner.

If the cheetah eats every deer they will get extinct and there is not deer to eat any more, so there must be an equilibria between predators and prays so is more than a zero-sum game.
