How does natural selection lead to evolution ?

Natural selections acts as the main driving force in the process of evolution.

Explanation:

Natural selection may be defined as the process by which organisms that can adapt better in their environment will survive in the population and reproduce more in the population. Natural selection acts as a force for evolution. The theory of natural selection was given by Darwin.

The resources are limited in the nature. The limited resources is responsible for the competition among the individuals. The individuals that can survive in the population can adapt better in the environment. They will reproduce and pass down the beneficial trait to their next generations. The frequency of the beneficial trait will increase in the population and population will adapt more better in the environment. Thus, natural selection requires existing heritable variation in the population and thus, leads to the process of evolution.
