Sure. Dawkins himself has addressed it, so I'll just let him speak for himself: http://www.skeptics.com.au/resources/articles/the-informatio...

I found this by Googling for, "dawkins give an example of a genetic mutation or an evolutionary process which can be seen to increase the information in the genome". It was the top result.

Y'know, we live in an age of unprecedented access to information. It really is remarkable. At no time in human history has more information been more available to more people for less effort. Why, in this age, would you want to remain willfully ignorant?
