Re: Evolution uses up genetic diversity
This is where the question comes in whether mutations could provide the necessary genetic diversity to keep on changing. My short answer is that if they could they would have saved the cheetah by now.

Well, that was weird.

Re: Can mutation and selection increase information?
With a single phrase “Words don’t reproduce” New Cat’s Eye has tossed all the population genetics in the garbage (its proper place, too). Attaboy!
And yet, would the clone “revolution” be able to spontaneously evolve to such complex form as, say, “counterrevolution”? Apparently, point mutations are of no avail here: there are merely no “fit” enough intermediate forms, between “revolution” and “counterrevolution”. Incidentally, this is the very case of the so-called “irreducible complexity” associated with the notorious William Paley’s doctrine.
Paley or no Paley, the problem of “irreducible complexity” is the sad evolutionary reality, and we are to consider the possibility of macromutations, along with those point. Say, 7-fold chance mutation +counter would settle the problem, yet what are the chances for such a lucky occurrence to happen?
