A leading example of evolution given in biology textbooks has come unglued, evoking jeers and jubilation in the camp of creationists, who have been trying for years to expel Darwin from the classroom. The case is that of the peppered moth, which over the course of a few decades has changed its wing color from pale-peppered to black and back to peppered again in parallel with the rise and fall of industrial pollution.

People did not know that photos were actually of dead moths glued or pinned in place. And the moth actually doesn't like tree trunks!
