Whoa! Slow down. This discussion started when you quoted a passage from Paul Davies, and declared that the claim in that passage was “wrong.” I have just looked at the passage again. It seems to be about:
I don’t see any discussion of “inheritance” in the passage. (Or, for that matter, of evolution.) It looks to me as if Davies is saying that when individual organisms are built up, information determining the final form of the organism comes not only from the DNA but also from other sources. As far as I can tell, he is talking about ontogenesis, not phylogenesis. You seem to be criticizing him as if he is making a claim about phylogenesis. I think that is why you don’t understand the objections of the others. They are saying that as an account of ontogenesis, Davies’s remarks are unobjectionable. And you are not seeing this.
