Taking an example of white-winged moths and dark-winged moths of England in per and post industrialised era, explain evolution by natural selection .

a) How do the observations made duirng moth collection in pre- and postindustralized era in England support evolution by Natural Selection? b) Explain the phenomenon that is well represented by Darwin's finches other than natural selection.

"Appearance of melanised moths post-industrialisation in England is a classic example of evolution by natural selection." Explain.

By taking industrial melanism as one example. Explain the concept of natural selection.

A study of white winged and melanised moths made in England before and after industrialisation in 1850 and 1920 respectively , supporting evolution by :

How does the population change in peppered moth, Biston betularia, explain natural selection?

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.

Assertion :- In England, before industrialisation, it was observed that there were more white-winged moths on trees than dark-winged or melanised moths. Reason :- White winged moths can survive in non industrialised area.

Explain how natural selection operates in nature by taking an example of white winged and dark winged moths of England.
