The Peppered Moth story is an old one of course. It is important because it seems to be the best example of Natural Selection cited in reference works. It is good to know that the experiments hold up under scrutiny, because I heard that some questions have been raised.
This makes it important that the Peppered Moth study substantiates the view that ecology is the basis for Natural Selection. The change in the coloration of the moth was the result of the environment, not by the struggle for survival with other moths.
When I read Coyne's article on the validity of the Peppered Moth studies, I found that he recommended two books for additional information. The first was Weiner's Beak of the Finch, which I have read and is a good book. On the other hand on Amazon I read reviews by people who claimed to be experts who said that the book contained serious errors, because I gathered it said that ecological factors caused Natural Selection. Very strange.
The other book that was recommended, Endler's Natural Selection in the Wild, was priced at $88.00 and the one review called it a hand book for research, not research of Natural Selection itself.
'If some organisms were not entirely self-seeking, they, and Nature in general, would be more ethically acceptable. In most theological systems it is necessary that the creator be benevolent and that this benevolence is shown in his creation. If Nature is found to be malicious or morally indifferent, the creator is presumably too. For many, peace in mind might be difficult with the acceptance of these conclusions, but this is hardly a basis for making decisions in biology'.
This sentence is still today too big a swallow for the moral elite, unable to comprehend their own Darwinian behaviour and unable to think about the fact that 'natural selection, albeit stupid, is a story of unending arms races, slaughter and suffering' (G.C. Williams in 'Plan and Purpose in Nature').
This is a quote from George C. Williams' book against Group Selection which influenced Dawkins' Selfish Gene and makes a scientific case against God based on Darwinian Natural Selection of Survival of the Fittest.
