So, as time goes on, species can only lose genetic information, but never gain it. So, over time, we will all slowly devolve, as genetic information is lost, but never (re)gained. Thus, you are postulating a sort of 'evolution-in-reverse', starting with a mystical creation, and ultimately ending with us slowly turning into bacteria, and then nothing at all. Now that's a new one! I like it! I know, I know, the evidence supports nothing of the kind, but still, there's a science fiction novel in there somewhere.
