How do mutations relate to natural selection?

Answer 1

Mutation occurs when the organism is introduced to a new environment or some sort of change which it needs to adapt to.

When a boy from Bangladesh, which has a tropical climate, moves to Russia, which has a cold climate, his body will take some time to adapt. If the boy had a recessive gene that makes him more resistant to the cold, it will now be expressed. When the boy has offspring with a female, that gene will be passed on to increase the offspring's chances of survival because of selection pressure and natural selection.
