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).
The book's reception led to claims that the peppered moth evolution story ought to be deleted from textbooks. [29] [30] Scientists have examined the allegations made by Hooper, and found them to be without merit. [31] [32] [33] Majerus described the book as "littered with errors, misrepresentations, misinterpretations and falsehoods". [23]
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 ...
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.
In 1924, J.B.S. Haldane calculated, using a simple general selection model, the selective advantage necessary for the recorded natural evolution of peppered moths, based on the assumption that in 1848 the frequency of dark-coloured moths was 2%, and by 1895 it was 95%. The dark-coloured, or melanic, form would have had to be 50% more fit than ...
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 ...
Poulton's 1890 book, The Colours of Animals, written during Darwinism's lowest ebb, used all the forms of coloration to argue the case for natural selection. Cott described many kinds of camouflage, and in particular his drawings of coincident disruptive coloration in frogs convinced other biologists that these deceptive markings were products ...
Biston is a genus of large, long-winged moths belonging to the family Geometridae. It is most notable for containing the well-known peppered moth . The genus was first described by William Elford Leach in 1815.
