(8.11C) Before the Industrial Revolution in England, the peppered moth was commonly found on tree trunks that had light-colored lichen on the bark. Most of the peppered moths were a light grey-brown color similar to that of the lichen. A few of the moths had a mutation that made them a dark grey-brown color.
