Coyne responded by saying, "Despite the defensiveness of British evolutionists, I think my criticisms carried some weight, because Cambridge biologist Michael Majerus decided to repeat Kettlewell's experiments, but doing them correctly this time." He quoted the Cook "et al". conclusion that "These new data answer criticisms of earlier work and validate the methodology employed in many previous predation experiments that used tree trunks as resting sites. The new data, coupled with the weight of previously existing data convincingly show that 'industrial melanism in the peppered moth is still one of the clearest and most easily understood examples of Darwinian evolution in action'." Coyne said he was "delighted to agree with this conclusion, which answers my previous criticisms about the "Biston" story."
