What is evolution and how is natural selection related?

Natural selection leads to evolutionary change

Explanation:

Natural selection is a process by which the species adapt to their environment. Thus individuals have a better chance of survival and evolution and transfer their traits to offsprings. As the process of evolution cannot take place without genetic mutation or diversification of genetic buildup. The occurrence of repeatedly branching events take place in which new species splits from a common ancestor producing a multi-level tree. For example, in the event of climate change, those species capable of tolerating the temperature will not die as compared to those which are not capable of tolerating and thus will not reproduce. If the same process is repeated over millions of years of the time the population will get adapted to their new climate and develop genes that combat these drastic changes.
