Re: Why try to 'convince' creationists?
When London's sooty atmosphere was at its worst they were much darker, to provide camouflage against blackened buildings.Much like Kettlewell's famed peppered moths? Most of us probably can recall from biology class being taught how peppered moths developed a dark form in response to industrial pollution to protect themselves against predation by birds. Dark moths being harder to see against the blackened tree trunks.
Unfortunately, Kettlewell made it all up. Peppered moths are nocturnal and spend their days hidden in crevices on the underside of tree branches. The picture of the two forms, light and dark made a wonderful cover for Scientific American, but it was posed. Both forms, light and dark, existed before the industrial revolution. But it's good "story".
I believe the main predators are bats and owls.
