Need some help refuting this creation argument...

[Aractus]

I was tempted to dismiss this (I don't even know this person particularly well) but I can't shake the feeling that a well put together email could completely change this guys retirement from open minded wonder at the universe as science reveals it.......or close minded crack pottery.

Dave, I stopped reading after the first line ...

• The Mathematical Impossibility of Evolution
  According to the most-widely accepted theory of evolution today, the sole mechanism for producing evolution is that of random mutation combined with natural selection.

That's the neo-darwinist view of the "selfish gene", it's wrong and outdated. Evolution operates primarily in the real physical world, and not in DNA world. DNA is an adaptable mechanism which appears to be able to re-order itself with some degree of stability without "random chance" events required to trigger it. The most important thing to remember is that most DNA is "junk dna" and unused. All the organism needs to do is switch a protein that reads a new section of DNA, and the existing code becomes junk and the junk becomes what is used. It is this switching process that appears to make evolution at the pace that it happens possible, and not random-chance-mutations. But that said, the theory isn't done and closed.
