In evolutionary terms, what kind of force is mutation?

Question

Quizplus · Accepted Answer

Mutation is considered a positive force in evolution because it generates genetic variation that can be selected for in a changing environment. It is through mutation that new traits and adaptations can arise, leading to the evolution of new species over time. While not all mutations are beneficial, the ones that confer a survival advantage will tend to be favored by natural selection, leading to their increased frequency in a population.
