I'll take this as another opportunity to try to explain that it seems to me we just aren't talking about the same thing. srs doesn't want me to call this incommensurability, but whatever word we use, we don't appear to be talking about the same thing.
I don't recall that you've explicitly defined what you mean by "evolution," but you give the impression that you would call any change evolution. At the same time, I'll assume you do not include a baby growing up to adulthood as evolution - but that is a change. So, I assuming you count some types of change as evolution but not all types of change. What types of change do you include then? If you mean any mutation of the gene pool ... if that's what you're going to call evolution ... then, yes, that version of evolution has been documented.
But to then conclude that mutation is responsible for all the changes that paleontologists claim to see in the fossil record is unsubstantiated. If that is what you mean by evolution, then, no, that version of evolution has not been substantiated. In fact, there is some evidence that says that won't happen. I am
not saying the evidence is conclusive and disproves evolution. I am saying there is
some evidence giving that indication. I'm sure evolutionary biologists will work dilligently and try to overcome the difficulties.
But what does all this mean in light of the previous example I cited? What does it say about the conclusion of Forester that evolution should occur given the proper population size, and what does it say of "scientific" studies done on populations that don't meet his criteria? Again, it's all about the assumptions.
If you're going to ask, "What evidence?" I can cite M.K. Burke's article in Nature.
