Yeah but you see what I am saying right: kittens don't fight with kittens to survive - Evolution says normal kittens will just die out, because no one wants them anymore, until mutation will gives them something better than glow-in-the-darkness.
I mean realistically there is "a" challenge for glow-in-the-dark kittens, to be the greatest glow-in-the-dark kitten possible, but as pets part of the struggle to survive is mitigated - things go from survival of the fittest to popularity of the cloning (because people want the same glow-in-the-dark kitten that died already).
Really Evolution, if it was worth its salt as a theory, would have some advice to give on this kind of development: you are in danger of becoming a theory for theory's sake, if you have no philosophical balance and weight to bring to the table. I mean if you are really telling me that glow-in-the-darkness is not relevant to survival, give me some other word than Evolution, to help me evaluate the meaning of it - just daring to believe Evolution answers everything, is naive if you can't back it up where natural and unnatural Evolution part company?
