Microevolution refers to small-scale changes within a population, and the two principal factors that lead to it are new genetic variation and evolutionary mechanisms. New genetic variation can occur through mechanisms such as genetic drift, gene flow, mutation, or recombination, while evolutionary mechanisms include natural selection, genetic drift, gene flow, and sexual selection. These processes can result in changes in the frequency of alleles within populations over time.
