WebMay 6, 2024 · There are five evolutionary forces; three that create genetic variation (mutation, recombination and gene flow), one that changes the distribution of genetic variation randomly (genetic drift), and one force that molds the genetic variation (selection). Mutation Ultimately, the origin of all genetic variation stems from mutations [ 5 ].
