Well, what I mean is that we know that cells and small biological organisms can mutate. But isn't it also true that all life forms eventually cease to exist and that we have yet to see any life form actually improve on itself and mutate itself into a continuous life form.

So to my way of thinking things are actually 'devolving' not evolving.

(oh, and thank you for actually engaging in dialog instead of flaming).

I'm not sure what you mean. Yes, all organisms die, but the number of species has steadily risen over the last few billion years. Living things have evolved to occupy extremely specialized niches (like living in rocks, surviving thousand degree temperatures and even vats of acid). And we see organisms evolving all the time to carve out new niches and adapt to environmental pressuers.
