In England , in 1920 (after industrialization) when a collection of moths was made, it was observed that:

Before industrialization set in England :

Prior to industrialization, there were far more white winged moths on threes than melanised moths in England. However, after industialization, the distribution pattern of these two kinds of moths reversed. What does the above observation indicate? Explain giving reasons.

In the post-industrialization period in England

In England, before the Industrialisation set in, it was observed that there were more white winged moths on the trees. However after industrialisation, there were more melanised moths in the same area. This is an example of

How did industrialization play a role in Natural Selection of light and dark coloured moth in England ?

How did industrialization play a role in Natural Selection of light and dark coloured moth in England ?

The evolutionary story of moths in England during industrialization reveals, that "evolution is apparently reversible". Clarify this statement.

After the industrial revolution, melanic moths survived because
