"My understanding is that the latest research by Majerus confirms Kettlewell's original findings. The claims of fraud are from creationist propagandists. http://en.wikipedia.org/wiki/Peppered_moth "although various errors and oversights have been found in early experiments on peppered moth evolution, subsequent experiments and observations have confirmed the phenomenon and its initial explanation" - Thanks for the correction. I had read about the earlier improper experimentation but, improperly on my own, I had not followed up to find the new research. Excellent reference, well documented.
