Peppered moth evolution
The evolution of the peppered moth is an evolutionary instance of colour variation in the moth population as a consequence of the Industrial Revolution. The concept refers to an increase in the number of dark-coloured moths due to industrial pollution, and a reciprocal decrease in the population in a clean environment. Hence, the phenomenon is called industrial melanism. It is the first recorded and experimented case of Charles Darwin's natural selection in action, and remains as a classic example in the teaching of evolution. Sewall Wright described it as ""the clearest case in which a conspicuous evolutionary process has actually been observed.""The dark-coloured or melanic moths (carbonaria variety) were not known prior to 1811. After field collection in 1848 from Manchester, an industrial city in England, the frequency of the variety was found to have increased drastically. By the end of the 19th century it almost completely outnumbered the original light-coloured type (typica variety). The evolutionary importance of the moth was only speculated upon during Darwin's lifetime. It was only 14 years after Darwin’s death, in 1896, that J.W. Tutt presented it as a case of natural selection.Bernard Kettlewell was the first to investigate the evolutionary mechanism behind peppered moth adaptation, between 1953 and 1956. He found that a light-coloured body was an effective camouflage in a clean environment, such as in Dorset, while the dark colour was beneficial in a polluted environment like in Birmingham. This selective survival was due to birds which easily caught dark moths on clean trees, and white moths on trees darkened with soot. The story, supported by Kettlewell's experiment, became an example of Darwinian evolution used in standard textbooks.However, failure to replicate the experiment and criticism of Kettlewell's methods by Theodore David Sargent in the late 1960s led to general scepticism. When Judith Hooper's Of Moths and Men was published in 2002, Kettlewell's story was more sternly attacked, accused of fraud, and became widely disregarded. The criticism became a major argument for anti-evolutionists. Michael Majerus was the principal defender. His seven-year experiment beginning in 2001, the most elaborate of its kind in population biology, the results of which were published posthumously in 2012, vindicated Kettlewells' work in great detail. This restored peppered moth evolution as ""the most direct evidence"", and ""one of the clearest and most easily understood examples of Darwinian evolution in action"".
