Ok, I'll take a stab at "truthfully addressing post #557": It's a giant load of nonsense.
It, again, performs the classic Creationist fallacy of challenging someone to explain a hypothetical "single step" process which, sadly, bears no real resemblance to any evolutionary claim or process.
It's like asking the odds of a land-dwelling mammal giving birth to a whale in a single reproductive act. The answer is, "well I have to admit that's pretty f***ing unlikely, but since that's not what evolution claims happened, or how, what on earth are you babbling on about?"
