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.
no, there's only so much variability that can be lost. What I mean by that is they can only become so specialized and then it's that way from then on. Look, the reason why the animals can't breed anymore is a loss of information. Information is never gained. Many Biologists know this, it's a common fact.

But that does remind me of one of my old friends ideas. He believed in evolution and no God and he thought we were de-evolving. At the time I thought it was incredibly stupid ( and it was of course), but evolution teaches that it's an onward upward struggle. He wouldn't accept God, and so he came to the logical conclusion based on his belief, that things are de-evolving because humanity is becoming worse and worse and everything seems to be fallling apart.

I heard somewhere that even in the field of sports things are going down. People are averaging lower and lower from what I've heard. This may not be true though, I havn't looked for a credible resource yet.
