Question

Why are mutations considered important in evolution​

Answer 1

Mutations are one of the fundamental forces of evolution because they fuel the variability in populations and thus enable evolutionary change.

Answer 2

Mutations are considered important in evolution because they are the ultimate source of genetic diversity.

• Mutations are alterations in the sequence of an organism's DNA, caused by radiation or toxins in the environment. They can also form spontaneously during DNA replication.

• Mutations can have a variety of impacts. These are frequently dangerous or have little or no impact. However, changes in DNA sequence can occasionally be helpful to the organism.

• Beneficial mutations that offer a survival benefit or reproductive success are more likely to be passed on to subsequent generations, increasing their frequency in the population over time. This accumulation of favorable mutations is a driving factor in the process of evolution.

• Without mutations, there would be no supply of new genetic information, and evolution would be greatly hampered.
