460:, said Kettlewell's experiments had appeared to be "the slam-dunk of natural selection", but argued that the cause of the dark forms appearing was still an "irreducible mystery". Although not a creationist herself, Hooper argued that the peppered moth experiments failed to represent evolution. She claimed that Kettlewell's field notes could not be found and suggested that his experiment was fraudulent, on the basis of Sargent's criticisms alleging that the photographs of the moths were taken of dead moths placed on a log. She said that E. B. Ford was a "Darwinian zealot", and claimed that he exploited the scientifically naive Kettlewell to obtain the desired experimental results. She then alleged that scientists in general showed "credulous and biased" acceptance of evolution. The book's reception led to claims that the peppered moth evolution story ought to be deleted from textbooks.
440:, 14 March 1999, claiming that "the rise and fall of the peppered moth, is based on a series of scientific blunders. Experiments using the moth in the Fifties and long believed to prove the truth of natural selection are now thought to be worthless, having been designed to come up with the 'right' answer." Majerus regarded this view as surprising, and not one that would be shared by those involved in the field. He noted numerous scientific inaccuracies, misquotations and misrepresentations in the article, but thought this was common in press reports. He stated that he had spoken to Matthews for over half an hour and had to explain many details as Matthews hadn't read the book, but "Even then, he got nearly everything wrong."
411:, he stated that the most serious problem was that only two peppered moths had been found on tree trunks. He also wrote that the white moths had increased in numbers before the lichen had returned and that Kettlewell's findings of moths choosing matching backgrounds had not been replicated in later experiments. Coyne compared his reaction to "the dismay attending my discovery, at the age of 6, that it was my father and not Santa who brought the presents on Christmas Eve". He concluded that "for the time being we must discard

Majerus found that the review did not reflect the factual content of the book or his own views, and cited an assessment by the

He succeeded only by using freshly captured moths consisting of 9 black and 8 white types, which he released separately. He found that the birds preferentially caught the moths according to the background colour on which the moths were present.
152:. 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, and the melanic population could dominate the entire moth population after 13 generations. He concluded that "the only probable explanation is the not very intense degree of natural selection". University of Oxford zoologist

Based on his experiments between 1965 and 1969, he concluded that it was not possible to reproduce Kettlewell's results, and said that birds showed no preference on moth on either black or white tree trunks. He suggested that Kettlewell had trained the birds to pick moths on tree trunks to obtain desired results.
524:, in which he claims, "What the textbooks don't explain, however, is that biologists have known since the 1980s that the classical story has some serious flaws. The most serious is that peppered moths in the wild don't even rest on tree trunks. The textbook photographs, it turns out, have been staged." The arguments were dismissed by Majerus, Cook and

The experiment found that birds selectively prey on peppered moths depending on their body colour in relation to their environmental background. Thus, the evolution of a dark-coloured body provided a survival advantage in a polluted locality. The study concluded that "industrial melanism in moths is
