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

Read the following statements and select the correct option A. Increase in melanised moths after industrialisation in Great Britain is a proof for natural selection B. When more individuals of a population acquire a mean character value, it is called disruption C. Changes in allelic frequency in a population will lead to Hardy-Weinberg equilibrium D. Genetic drift changes the existing gene or allelic frequency in future generations.

The theory of evolution of species by natural selection was given by

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.

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