WebHenry 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 classic demonstration of ... Tutt was the first to propose the "differential bird predation hypothesis" in 1896, as a mechanism of natural selection. The melanic morphs were better camouflaged against the bark of trees without foliose lichen, whereas the typica morphs were better camouflaged against trees with lichens. As a result, birds would find and eat those morphs that were not camouflaged with increased frequency.
