But my biggest problem (among many) with evolution is not scientific. It has to do with my faith. I believe humans are different from animals because we have souls. But what was the dividing line between ape and human? If we evolved from apes, at what point did we get our souls? Did God one day decide that every ape that had a certain mutation would get a soul, but the other apes were just out of luck because they weren't "human" enough? What was the genetic mutation that suddenly made apes human enough to warrant souls?
I hope I'm making myself clear enough on this issue, since stuff like this tends to get muddled when you try to explain it in writing, but if anyone who believes both in God and in evolution has a reasonable resonse to this, I'd love to hear it.
Oh, and let me also say that I believe in natural selection on a micro-evolutionary scale, but not a macro-evolutionary scale.
The problem is that we have been cautioned to not mess with the Tree of Life. So long as we stick to classification there would be no problem, but genetic engineering of ourselves, which where all this appears to be headed, could be Big Trouble. Genetic engineering of plants and animals could also be dangerous but isn't quite the Big Trouble.
