<em>Black moth</em>
Explanation:
During the time of the industrial revolution, the lichen that covered all the trees previously got killed. Due to the pollution arising from the industries, the colour of the woods of the trees turned into black. As a result, the light- coloured moths were not able to hide from their predators as their colour no longer matched with the colour of the trees. The black coloured moths were more adapted to survive in this environment because their colour matched with those of the woods of the trees. They were better adaptable to live in the Industrial Revolution.
