> Assuming a scientific testing gloss, each new genetic code variation X can be considered as a hypothesis, that "variant X is fit", and then natural selection events that act on copies of X (for or against) serve as experiments testing the hypothesis

this is the problem i have with natural selection... it has no predictive power. You can never use natural selection theory to say if an organism is "fit" before it exhibits its fitness. what good is this?
