Dawkins may be a ‘master’ of style, but he didn’t get evolution right, and his claims for NS climbing Mt. Improbable are simply false.
The site eonic-effect.net has a whole series on this:
The Eonic Effect: Climbing Mt. Improbable
If you want to climb Mt. Improbable you need a macroevolutionary driver to do that. Natural selection is NOT enough.
Face it, Dawkins is a peddler of myth, whose stylistic pluses have earned him an audience wishing to believe and hoping for someone who can fulfill that pipedream and make it look like science.
