No, it most certainly does not have relevance to mechanism. One of the first things we teach freshman students about thermo. is that it tells you the end result and the direction of a process; it says nothing about the rate or the route.
The various statements of the Second Law all have an implicit understanding of the mechanism.
The second law is one statement (or two if you include the limiting case that the entropy change in a reversible process is zero). I have no idea where you get 'the various statements of the Second Law', other than your own imagination.
Thermodynamics does pose problems for evolution, though evolutionary advocates fight it tooth and nail.
Utter tripe.
RWP: Utter tripe.
Perhaps you should have taken some more time to read through the current debate at ARN I linked you to.
