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. He was investigating the cause of the appearance ...
Bernard Kettlewell. 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. This experiment is cited as a ...
Michael Eugene Nicolas Majerus (13 February 1954 – 27 January 2009) was a British geneticist and professor of evolution at the University of Cambridge. He was also a teaching fellow at Clare College, Cambridge. He was an enthusiast in Darwin's theory of evolution by natural selection and became a world authority in his field of insect ...
The evolution of the peppered moth is an evolutionary instance of directional colour change in the moth population as a consequence of air pollution during the Industrial Revolution. The frequency of dark-coloured moths increased at that time, an example of industrial melanism. Later, when pollution was reduced, the light-coloured form again ...
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).
QH375 .H66 2002. Of Moths and Men is a book by journalist Judith Hooper about the Oxford University ecological genetics school led by E.B. Ford. The book specifically concerns Bernard Kettlewell 's experiments on the peppered moth which were intended as experimental validation of evolution. She highlights supposed problems with the methodology ...
Kettlewell then performed field experiments using mark-recapture techniques to investigate the selective predation of moths in their natural habitat. These experiments found that, in woods near industrialized areas, melanic moth forms were recaptured at much higher rates than the traditional lighter-colored forms, while in non-industrialized ...
John Burdon Sanderson Haldane FRS (/ ˈhɔːldeɪn /; 5 November 1892 – 1 December 1964 [1][2]), nicknamed "Jack" or "JBS", [3] was a British-Indian scientist who worked in physiology, genetics, evolutionary biology, and mathematics. With innovative use of statistics in biology, he was one of the founders of neo-Darwinism.
