Is it your understanding that Dawkins and Wilson (or any other reputable scientist) disagree about the information content of genes? If so, can you provide a source for that?
More to the point, that quote doesn't refer to the information content of genes at all. You'll certainly agree that it doesn't do so explicitly. Can you find a quote that explicitly says that someone disagrees with Dawkins about the information content of genes? Maybe in the Wikipedia articles for gene selection and kin selection?
