Maybe it's an incorrect presumption that genomes need new information to cause it's (host) to evolve.
Is this what you mean?
A genetic mutation is new "information". You have to remember that your DNA is pretty much an organism's blueprint/assembly instructions. A mutation can be actual "new" inserted information (new base pairs), but even just shifting existing code changes the "blueprint".
Imagine it as assembly instructions for a house. If you were just to swap the words "roof" and "floor" in certain areas, the assembly instructions would be completely messed up and you would build one messed up house (if it would be able to be built at all). No new information was technically added, but just switching some words made the actual instructions "new".
I think that is why Dawkin's took a while to think and then answered the way he did. The question wasn't really a question, it was a statement. A genetic mutation essentially IS new information. I think the questioner was looking for an example where 1 mutation made a new species or something and Dawkins was trying to explain how it is an extremely long process of random mutations and natural selection.

That article goes into a little greater depth and there are some great links at the bottom of the article.
If you are seriously interested in Evolution/Biology I'd highly suggest you pick up a few books ("The Origin of Species" Darwin, "The Greatest Show on Earth: Evidence for Evolution" Dawkins, "The Selfish Gene" Dawkins, "Molecular Biology of the Cell", etc etc).
This is the year. We put our failures in the past, it's a new year, a new defense. It's time to prove to the league that the Patriots are back and aren't going anywhere and they will be the last ones standing in Feb.
Update: Well that didn't work out as I had planned. Next year baby, next year 19-0 we go. Next year.
