I think it makes an interesting point, that if Evolution were proven wrong, the part of the theory that was inaccurate would be relegated to the sin bin, never more to evolve.
There are two factors here: one, the most that something can evolve (if it is true), the connection with the rest of the theory that part of it has (if it is true or false).
The point is, the context for Evolution is largely manufactured, as long as it points to monkeys and mutation - but the point will come, when survival is fitter without these things (something we can predict will be distanced from, based on the Devil's behaviour when he knows the territory of his prey is caught).
I don't know when the Devil is going to attack these aspects of the theory of Evolution, but I know that Biblically I am on solid ground when I say "species and kind are properly defined" - that should be food for thought.
