@thomasfuchs I’m not sure I follow. Instances of one species wiping out another happen all the time. Are they all temporary, statistical outliers? On a long enough time scale, sure. But on a long enough time scale, all life is temporary, equilibrium or no, so I don’t see how evolution optimizes for one versus the other. Evolution may have long periods of stasis followed by bursts of extinctions and rapid competition, but after those rapid periods, a new equilibrium occurs, with different dominant actors. To call one state “favored” over another, I think is incomplete.
But what do I know, I’m not an expert on the subject.
