  2. Peppered moth evolution - Wikipedia

    en.wikipedia.org/wiki/Peppered_moth_evolution

    Industrial melanism in the peppered moth was an early test of Charles Darwin's natural selection in action, and it remains a classic example in the teaching of evolution. [ 1 ] [ 2 ] [ 3 ] In 1978, Sewall Wright described it as "the clearest case in which a conspicuous evolutionary process has actually been observed."

  3. Kettlewell's experiment - Wikipedia

    en.wikipedia.org/wiki/Kettlewell's_experiment

    For example, J.B.S. Haldane estimated in 1924 the rate of evolution by natural selection in the peppered moth in his first series of A Mathematical Theory of Natural and Artificial Selection. He estimated that for the peppered moth having reproductive cycle in a year, it would take 48 generations to produce the dominant (melanic or black) forms ...

    en.wikipedia.org/wiki/Peppered_moth

    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.

  6. Natural selection - Wikipedia

    The balance was reversed by the effect of the Clean Air Act 1956, and the dark moths became rare again, demonstrating the influence of natural selection on peppered moth evolution. [59] A recent study, using image analysis and avian vision models, shows that pale individuals more closely match lichen backgrounds than dark morphs and for the ...

  7. Coloration evidence for natural selection - Wikipedia

    en.wikipedia.org/wiki/Coloration_evidence_for...

    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

    His research work was largely focussed around insect species, particularly the peppered moth and ladybirds, but explored these from many different perspectives including melanism, [16] male killers, [17] [18] sexual selection, [19] [20] sexually transmitted diseases, [21] animal colouration, [22] invasive species, [23] [24] and biological pest ...

    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 ...
