Moth study backs classic 'test case' for Darwin's theory
Quote:
For more than a century it has been cited as the quintessential example of Darwinism in action. It was the story of the peppered moth and how its two forms had struggled for supremacy in the polluted woodlands of industrial Britain.
Every biology textbook on evolution included the example of the black and peppered forms of the moth, Biston betularia. The relative numbers of these two forms were supposed to be affected by predatory birds being able to pick off selectively either the black or peppered variety, depending on whether they rested on polluted or unpolluted trees.
It became the most widely cited example of Darwinian natural selection and how it affected the balance between two competing genes controlling the coloration of an organism. Then the doubts began to emerge.
Critics suggested that the key experiments on the peppered moth in the 1950s were flawed. Some went as far as to suggest the research was fraudulent, with the implication that the school textbooks were feeding children a lie.
Creationists smelt blood. The story of the peppered moth became a story of how Darwinism itself was flawed - with its best known example being based on fiddled data.
