In England, prior to industrialisation the tree trunks were covered with white lichens, and therefore white moths could survive and got protected from predators due to white colour, whereas black (a dark winged moths) could be easily identified due to dark colour and declined in numbers.
But as industrialisation progressed, the lichens were replaced by soot and dust particles and dark coloured moth were benefitted due to camouflage, while white winged moths could be easily eaten up by the predators being easily identifiable. Thus, only the dark winged moth who were able to fit and survive in conditions reproduced well in nature. This is how natural selection operates in nature.
