Solution
Importance of mutation in organic evolution is genetic variation.
Explanation:
Mutations introduce new genetic information by creating sudden hereditary changes in the genetic makeup of organisms. They are the ultimate source of new and different genetic material in populations, increasing genetic diversity which is essential for evolution. Mutations, along with genetic recombination, provide heritable variation on which natural selection can act, driving evolutionary change.
