One of the best creationist arguments I have heard concerns the "backward" pouch of the wombat. Opposite to most marsupial pouches, the wombat's opens to the rear, which is valuable to it, as a burrowing animal, for keeping dirt out of the pouch. But how could the pouch turn around by natural selction?
When I first heard about this problem, I thought that the answer that would satisfy natural selection would be that the wobat evolved its pouch seperatly from marsupials that evolved front-opening pouches. But I just saw a TV show that said all of the world's marsupials have a common ancestor: a rat-like animal that lived in China.
So is there a well known solution to this probalem that I have missed? I searched the web and the EVC forums for discussion on it, but found none. Could the pouch have flipped around in one fell swoop, with a single genetic mutation? If so, wouldn't other simultateous mutations have had to occur to make the new pouch work? And if the pouch transitioned in a series of small steps, what would that have looked like?
