 The point of stating conditions for evolution by natural selection need not be to state the conditions of deployment of a particular theory in the special sciences. Godfrey-Smith mentions that the principles may be important to discussions of extensions of evolutionary principles to new domains. Statements of the conditions for evolution by natural selection might have value for other reasons. But evolutionary theory is, despite the name, at least arguably a theory that is applicable to more systems than just those that evolve, as the replicator selectionists would have it.
