Kettlewell's experiment was a biological experiment in the mid-1950s to study the evolutionary mechanism of industrial melanism in the peppered moth (Biston betularia). [ 1 ] [ 2 ] It was executed by Bernard Kettlewell , working as a research fellow in the Department of Zoology, University of Oxford .

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.
Industrial melanism is known from over 70 species of moth that Kettlewell found in England, and many others from Europe and North America. [17] Among these, Apamea crenata (clouded border brindle moth) and Acronicta rumicis (knot grass moth) are always polymorphic, though the melanic forms are more common in cities and (like those of the peppered moth) are declining in frequency as those ...
The peppered moth (Biston betularia) is a temperate species of night-flying moth. [1] It is mostly found in the northern hemisphere in places like Asia, Europe and North America. Peppered moth evolution is an example of population genetics and natural selection. [2] The caterpillars of the peppered moth not only mimic the form but also the ...
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. He was also an enthusiastic educator [1] [2] and the author of several books on insects, [3] [4] evolution [5] [6] and sexual reproduction. [7] He is best remembered as an ardent supporter and champion of experiments on peppered moth ...
James William Tutt (26 April 1858–10 January 1911) was an English schoolteacher and entomologist.He was a founding editor of the journal Entomologists' Record from 1890 and published a landmark series on the British Lepidoptera in which he described numerous species of moths [1] and was among the first to notice industrial melanism in the pepper moth Biston betularia and was among the first ...
