Peppered moths back to form

The Daily Mail is reporting that the peppered moth, Biston betularia is now reverting back to its light form because of improvements to the environment. Of course this story is presented as evidence of evolution, but in reality it is just a change in the ratio of the numbers of the light and dark form. In other words, evidence of natural selection on pre existing genetic material, not an example of evolution at work.

Other factors may also be involved. Judith Hooper's book 'Of Moths and Men' provided some interesting discussion about environmental factors that may change the moths colouration during the caterpillar stage.
