those are two components of the explanatory theory of the mechanism, yes.
there is also the explanatory theory of the evidence, which led to the development of several evolutionary theories, most of which disproven by science, one of which generally supported and expanded by science.
but this is well beside the point: I have -by your posts- been led to believe that there is no valid purpose served in even attempting discourse with you.
The 'record'. How did one end up here, and not there, what uplift, what stream, what flood, etc?
But that's not evolution. You have the fact, however you define it, whatever you mean by it. And you have my question - do you have a theory, or some alternative theories, that might explain how it came to be, and continues to this day (supposedly)? Or is it just an irreducible fact, and that's as far as we go? No natural selection? No chance? No mutation? No populations? No genetic drift and the like? Evolution is just a fact - see - I drop this apple (just like that)?
