Explanation:
Charles Darwin explains evolution and their genetic material evolves during the process. For example, fruit birds have narrow bills whilst seed-eating birds have big bills. The foods they eat forced their DNA to adapt with the system in order to survive.
The processes of mutation and natural selection can result in genetic variation in a population.
Variations are changes which occur in the structure and genetic composition of organisms of the same species.
Variations in genetic material results in formation of new species.
Some methods of genetic variation include:
Therefore, the processes of mutation and natural selection can produce variations in genetic material in a population.
