You should be more clear here, because this one is still used as a very "simple case" of evolution. Pigliucci treats it thoroughly in "Denying Evolution."

Thank you for your correction. See the Ken Miller explanation. It is an adaptation to bird predation, not a color camoflage issue. Pinning the moths to trees was not natural methodology and confused the issue.:
