Not just that, but also "UK moths" and "matching pollution." Very sloppy from a soi-disant scientist I should say.

I have asked him to not address me or refer to me on this forum. He can't help himself and it's extremely annoying.

In fact, the changes in proportions between the two colour variants of the peppered moth are not an example of evolution at all. Before the Industrial Revolution blackened tree bark, etc, the two variants already existed, as they did all through the period of worst smoke pollution and as they do now. All that's changed is the proportions. The origination of two morphs from a common ancestor, or as a favourable mutation from one or the other pre-existing form, IS evolution in action. The environmentally-forced changes in numbers could be seen as natural selection in action. Natural selection is a mechanism of evolution but is not evolution itself. We tore our hair out on the examiners' panel as we read hundreds of answers from 'A' Level students who had clearly been misinformed by their biology teachers. One more thing: this "example" of evolution became all the rage in classrooms from the sixties onward largely on the back of fraudulent science. Just thought I'd mention it. Piltdown Man, anybody?
