Say there are only white moths in some place that sit on white birch trees (the theory of Natural Selection does not apply here, because there is no variation). Does it have scientific merit to describe the wingcolor as contributing to the chance of reproduction of the moth? And then consider every other attribute the moth has, and how it functions in it's reproduction. Once you have accepted that it has scientific merit to describe organisms in such a way, you should know the theory of Natural Selection (differential reproductive succeess), to be either false or a subset-theory (competitive reproductive success) to a general theory of reproduction.
Variation comes from mutations not from Natural Selection, or did I missunderstand what you said?
However, Natural Selection, as I understand it, goes something like this:
1) There is an exponential increase in numbers.
2) There are a limited number of resourses.
3) This results in competition.
4) Certain creatures (plants, animals, etc) are better able to produce offspring (due to mutation).
5) These will come to dominate the population.
It should be noted that without mutations Natural Selection will have no 'raw materials' to work with.
I don't see how it could be otherwise?
