Step-by-step explanation:
Mutations and genetic variation are important drivers of biological evolution. Mutations are random changes in an organism's genetic material that can lead to new traits or characteristics. Genetic variation refers to the diversity of genes and traits within a population, which can be generated by mutations or through other mechanisms such as sexual reproduction.
Through the process of natural selection, the survival of the fittest traits leads to the propagation of certain genetic variations over others. Individuals with traits that confer advantages in their environment are more likely to survive and reproduce, passing on those advantageous traits to their offspring. Over time, this process can lead to the evolution of new species or the adaptation of existing species to changing environments. Overall, mutations and genetic variation are critical components of biological evolution and the ongoing diversification of life on Earth.
