Mutation leads to evolution because it
The correct answer is: D
Explanation
Mutation leads to evolution by introducing genetic variations within a population, which natural selection can then act upon, favouring individuals with advantageous mutations that allow them to survive and reproduce more successfully, thus passing on those beneficial traits to future generations, gradually changing the characteristics of the population over time and leading to evolution; essentially, mutations are the raw material for evolution, providing the diversity needed for natural selection to operate.
