That is what makes the genetic evidence so important. The issue is not materials. It is the organization and pattern of the genetic instructions that is so important. What we are seeing is recipes that go from simple animals to more complex animals to humans but that use not just the same ingredients but the same methods for cooking, frosting, arranging the plates, etc. That is the evidence that Darwin was right.
Diversity comes from sexual reproduction and diversity in a changing environment is a good thing.
I'm very interested in this. I think God and evolution can get along quite well. But the way for them to co-exist is not to deny the evidence in our genes in favor of the creation story in the Bible. There is absolutely a place for a creator. But I think our genes tell us a message about how life evolved once created.
