I think Phil may be saying that persistent moral systems must be evolutionary stable, though that raises the question why the moral system needs to be persistent. One might argue that a species that can’t support its existence in a moral way should accept its own extinction (that is, the individual members of the species should accept the extinction of the whole species), along with the moral system that led to that conclusion.
