Just compare a gene like transaldolase for bacteria and humans. You can easily see that the gene has evolved neutrally with some changes inevitably being made because of the constant mutation rate.
How does this show how the gene has 'succumbed'.
Your writing here is laced with value statements that betray that you're just looking for facts to back up your position, rather than letting the facts take you where they lead. For example,

What I am saying is that an RNASE gene cannot evolve into anything other than an RNASE gene. Sure, RNASE1B is an interesting example of an adaptation facilitated by (degenerative) evolution, but it is just a variation on the same theme. For the broader theory to be true, duplicates have to be able to evolve distinctly new functionality. A modification of a modification isn't going to result in anything really novel.
What is 'degenerative' evolution? 'Degenerating' from what? A 'perfect creation'?
The mutation provided a 'distinctly new functionality' - in the example you cite, accessing a new diet. How is this 'degenerating'? You seem to be applying some sort of sliding scale where novel functionality is not novel enough unless the gene has a new name.
It's great to be skeptical, but you're not being skeptical, just looking for data points to support your presupposition.
