Another passion of mine is the Creation/Evolution debate. I've been active on the newsgroup Talk.Origins for several years.
I'm strongly pro-evolution, and I feel that accepting the science of evolution doesn't mean one must give up one's religious beliefs. One famous biologist is Dr. Kenneth Miller, who wrote a book called Finding Darwin's God which discusses how one can believe in God, and accept evolutionary science. Here's a video of Dr. Miller discussing the evidence for evolution of whales.
Dr. Miller's newest book is "Only a Theory: Evolution and the Battle for America's Soul" and is available at Amazon.com
