Solution
The main factor that determined the survival of different winged moth populations is their ability to camouflage themselves against their background. The white:winged moths were able to survive before industrialization because they could hide in the background of the almost white:colored lichen on the trees, while the dark-winged moths were able to survive after industrialization because they could hide in the darker background caused by industrial smoke and soots.
