BTW, Gore, your firm opposition to the notion that species are capable of the slightest independent genetic change would suggest that you are a fixed species man. Most young earth, strict creationists allow for rather considerable genetic change, arguing, for instance, that the entire Equid family may well represent a single "created kind," even though all species of horses, asses, and zebras have different chrosome numbers, and therefore reorganizations in their DNA well beyond what you would countenance.
Creation science types generally take profound offense if they are stereotyped as holding to fixed species. Are you the embodiment of the elusive stereotype?
I have never heard of any anti-evolutionist say that you can make hundreds of new DNA bases at random, so I think you are putting words in the mouths of others. I do not hold to fixed species in the sense you speak of either. Species have a very large gene pool. That's how we can get everything from wolves to chihuahuas to great danes from a single gene pool without any mutations.
