Why did you quote that bit? That was about convincing someone about the fact of evolution in the real world.

As to your larger issue, the fact remains that without heredity and sufficient selective pressure, the Grimm are definitionally not evolving. Definitions don't change, even if the laws of physics do. As long as cellular biology works mostly the same, evolution will happen. I'm not sure I see the point you're trying to make.
