"..off the shelf nonsense"......such as ?      Trying to confuse creationists is a common evolutionist tactic....aka equivocation or bait and switch. Take that snail mega lab link, how does that demonstrate slimy snail to scientist snail, yet it is called evolution! Certainly not, as far as the general theory, as for example outlined by kerkut, is concerned.               Ebbie, the new Pete is insisting he is the same person as old Pete. Well, shimrod, seems I have read more about lemski and his bugs than you have, and I don't think citrate digesting bugs under airless ?conditions constitutes evidence of microbes to man evolution.   So I will quote snail again.....show me some evolution,....rather than the bait and switch of offering natural selection.       And complaining that I read creationist stuff is irrelevant. You either got a reasoned argument or you ain't .               Guest somebody, no problem with genetic variation....within the kind....howsoever caused.
