Peppered moth insularia on the bark of a lichen-covered birch. By the time of Kettlewell, it was known in England that there were three varieties of peppered moth. The normal, typica, is whitish-grey in colour with dark speckles on the wings. The colour was a perfect camouflage on light-coloured trees covered with lichens.

The experiments with the peppered moths, as described in this book, are arguably the most dramatic and best known case of adaptive evolution.For many people at that time, this was the first evidence that they could see evolution taking place in the world around them, and could see how fast evolution can go since Darwin came up with the hypothesis (Kettlewell, 1959).

He was widely noted for his work on moths and ladybirds and as an advocate of the science of evolution.

Between 1953 and 1956, the geneticist Bernard Kettlewell experimented on peppered moth evolution. He presented results showing that in a polluted urban wood with dark tree trunks, dark moths survived better than pale ones, causing industrial melanism , whereas in a clean rural wood with paler trunks, pale moths survived better than dark ones.
Henry Bernard Davis Kettlewell (24 February 1907 – 11 May 1979) [1] was a British geneticist, lepidopterist and medical doctor, who performed research on the influence of industrial melanism on peppered moth (Biston betularia) coloration, showing why moths are darker in polluted areas.
