Don't you think that an unreasonable burden of proof?
Do you think that ID will ever go away if we have to "prove" evolution that way?
I was thinking about this some more.
Obviously, a detailed, step by step model, including every protein substitution ever made in the progress from pond scum to lawyers would be unreasonable. I think considerably less than that would fit the bill.
What do I think it would take to relegate ID to a fringe belief? i.e something that not only scientists, but also most of the general public, rejects.)
I think it would take two things.
First, a plausible theory of abiogenesis, with some form of experimental confirmation. Such confirmation would ideally include a laboratory demonstration in which simple molecules, minerals, etc are poured in, and some sort of replicating, self sustaining, proto-organism that includes at least some complex molecules comes out. If those Penn State guys are really onto something, I actually think they might be able to do that in a few years. The model is simple enough. You could get the reactions going. The only question is whether you could get it to form anything remotely like a cell. Could you get a free floating bag of reacting chemicals that can absorb, excrete, and divide? If you get there, you’re done.
However, if that is too much to ask for, a computer simulation or model, showing step by step actions, of the same would probably be adequate. It would have to, at the very least, show every specific chemical reaction required.
Second, a step by step model, showing the change in DNA along the way, and the protein modifications that result, for one species evolving into another. The species wouldn’t have to be complicated, but they would have to be multicellular and the changes would have to result in some sort of visible morphological change. The flagellum is a good start, but even if the research is completed, it won’t be good enough to put the issue to bed. To convince the skeptics, you’ll have to be able to say, “Here’s how the DNA got moved around, and here is how these critters are different because of it.”
Is it unreasonable to demand that? It certainly is unrealistic to expect it in the near future, but since when is it unreasonable to ask for experimental confirmation of a theory?
