Show Hint
Natural selection helps an organism in adapting to the environment by making changes in its genes.
- A genus
- A population
- An individual
- A species
The Correct Option is C
Solution and Explanation
Natural selection is a process by which an organism gets adapted to its environment by making selective changes in its genetic constitution. The unit of natural selection is an individual since genes work at an individual level.
Natural selection occurs to maintain the survival of a species by making favourable changes in its genes that helps it cope up with the changing environment. These changes are heritable and are passed on to the subsequent generations eventually leading to evolution. In the process of natural selection, organisms with more favourable changes will only survive and reproduce.

Evolution
Evolution is a process that occurs in changes in the genetic content of a population over time. Evolutionary change is generally classified into two: microevolution and macroevolution. The process of changes in allele frequencies in a population over time is a microevolutionary process. Three main mechanisms that cause allele frequency change are natural selection, genetic drift, and gene flow. On the other hand, macroevolution refers to change at or above the level of the species.
