you might perhaps not be surprised, stringsinger, that I think evolutionism is an absolutist position. I know it has many denominations [neo Darwin,punctuated equilibrium,multiverse etc] but the overall paradigm is sacrosanct.
dawkins is IMO not likely to accept evidence for the existence of God , but conversely he has been unable to present evidence for evolutionism. when asked for an example of a genetic mutation or an evolutionary process which can be seen to increase the information in the genome, he was stumped. the eventual answer given hardly addressed the question.
I should have thought this was pretty fundamental to Darwinism.
