During the Industrial Revolution in England, the trees became covered with soot. What were the effects of the Industrial Revolution on the peppered moths?

• The white moths stood out against the trees, so they increased while the black moths decreased.

• The soot covered trees allowed for both types of moths to increase as predators either couldn't see them (black moths) or were intimidated by the brighter color (white moths).

• The black moths blended better with the trees, so over time the black moths increased and the white moths decreased.

• The soot covered trees didn't affect the peppered moths and there were still more white moths than black moths.
