The natural evidence you are claiming important is survival of the fittest. By definition there is no moral code governing that process of interaction; there is only nonrational physical driving forces. Men have introduced moral codes to govern there behavior. Rand holds the noninitiation of force principle that I have proven already, in a previous post, preserves the essence of all men, not just the ones that are adept at coercion.
Social darwinism is not a moral code, it is simply a nonrational, natural order.
So you say. But you're just tossing out assertions and demanding that I accept them as true. I'm challenging you to prove your assertions like a good objectivist should.
