It's not a complete and final explanation of everything, but it's better than any other theory. There are always unexplained things in science, but I am not aware of any contradictions.

Natural selection is a pruning mechanism. It does not attempt to explain the source or cause of variation.

For well over a century biologists have looked for evidence that variation is non-random. There is precious little evidence of non-random variation.

Forgive me if I am being stupid. Would you consider environmental pressures that cause adaptation, random. I guess you could consider environment random, but there are patterns and balancing constraints that take it from my random category.

I should point out that (quite to my surprise), I have shown that random mutation combined with selection converges exponentially fast the local "fitness" function. I had thought that the convergence would be only linear.
