The ID movement hasn’t had many successes, but one area where they did pretty much succeed in causing considerable havoc was the classic textbook example of natural selection in action: the change in color of peppered moths (Biston betularia) from peppered white, to black, and back to peppered white again. Through a series of accidents that is still difficult to understand, the idea got started in the late 1990s that leading peppered moth researcher Michael Majerus had debunked Bernard Kettlewell’s famous study confirming the old hypothesis that the change in peppered moth color was due to selective predation of conspicious moths by birds.
