Quizplus · Accepted Answer

Mutation and sexual recombination are the two primary sources of the variability necessary for natural selection. Mutations introduce new genetic information into a population, while sexual recombination shuffles existing genetic information in unique ways, increasing genetic diversity. This variability allows for natural selection to act upon individuals with beneficial traits, leading to their increased survival and reproduction.
