What do you mean by " the principle " ,musket ? I would have thought that the guiding principle should be, does it accord with observable testable science, of which the general theory of evolution does not. Therefore, I say that microbes to multimuskets has never been demonstrated. Creationism however, does accord with observable science in a number of ways, but the evolutionary story contradicts it in many ways, as I have formerly pointed out.   So , go on. Show me some evolution !.
