Aw geez! I guess you got me there. Every five year old knows that peppered moths never ever rest on the trunk of a tree or any other part of a tree covered with bark.
Nice disinformation article.
The initial charge stands, even though the article tries to dance around it. Exposed bark is key to the study.
I fail to see why this is such a dogfight for evolutionists. There are others studies that are much more solid that clearly demonstrate environmental selection at work. There is obviously something more at work here than just science.
Just drop it already and use the example of smallpox in the New World.
