Natural Selection

If you were a peppered moth and you were white with black spots and the trees you are camouflaging on are also that color you would be happy, but later a factory makes steam and it makes the trees' wood black and your friends are black colored peppered moths and then they will be happy and you would not be because you cannot camouflage and you might die because of the birds that want to eat you, they might even love moths and that is even worse than birds that don't like moths. The factory moth thing really happens, let there is a picture showing a black moth and a white one camouflaging, in that picture both of them are save because the black one can hide in the broken pieces of the tree and the white one can hide in the white wood. Natural selection was discovered by Charles Darwin and he is really smart.
