You misunderstand evolution, somewhat, I think. Evolution simply selects for what works, it does not "refine" so much as it punishes failure. It does not perfect organisms for their environment, it simply allows what works. A good example is a particular nerve in the giraffe - and in plenty of other animals, but it is amusingly exaggerated in the giraffe - which goes from the brain, all the way down, looping under a blood vessel near the heart, and then all the way back up the neck to the larynx. There's no need for this; its just sufficiently minimal in its selective disadvantage and so massively difficult to correct that it never has been, and likely never will be. But, then, AI would be able to intelligently design itself, once it gets to a sufficiently advanced point. It would never need to reproduce to allow this refinement and advancement. It would be an entirely different arena than evolution via natural selection. AI would be able to evolve far more efficiently and without the limits of the change having to be gradual and small.
