Check out PatrickHenry's links. There's lots of them. Yes, I'm sure you'll bring out the beef with "micro" vs. "macro". But until a creationist discovers the mechanisim that limits evolution to a micro scale, then logic dictates that evolution continues unabated.
It's never been observed anymore than creation has. All of PH's links won't show that ANYONE has observed evolution happening. If that was true, it would be world wide. I don't get into debates on cre/evo threads because I already know what I believe and don't care about changing your mind.
