interesting DMcG and Steve disagree what natural selection is

We will have to wait for Steve, Pete, but I reckon you will find any such disagreement is entirely about whether the words I used were an adequate reflection of the concept. As far as I can tell we both agree on what that concept is and how it works. The 'disagreement' is about whether we best describe it in terms of the overall effect, or through detail, but we are still both describing the same thing.

Unless Steve disagrees, naturally.
