Nice Post Dwise1.
However, I fear you spent more time, consideration and effort than WS-JW has ever invested pondering the concepts of evolution. I suspect he will not return.
I have noticed a certain trend around.
Folks like WS-JW, highly intoxicated with creationist propaganda, blaze out into the world from their protected and unchallenged environment to expose the fallacies of the stoopid evilolutists; correcting the wrongs and setting people straight, like a shinning Don Quixote sitting high on their proud steed of "biblical truth".
They quickly initiate several wide offensive fronts, when they can't even adequately defend a single narrow front, and soon wither on the battlefield of reality confronted the first time with reason, logic and established facts. They are as you noted "armed with blanks". Typically they disappear after a few days never to return, sometimes with some parting comment like "I did my job and preached the truth but you do not have ears to hear or eyes to see ... you are hell bound ... your blood is not on my hands ... i shake the dust from my feet"
In this respect, the Creationist should really teach these eager beaver recruits of misfortune, your referenced quote from St Augustine and temper their enthusiasm with some sense of the magnitude and complexity of the questions at hand.
