- Evolution - Wikipedia
Evolution is the change in the heritable characteristics of biological populations over successive generations [1][2] It occurs when evolutionary processes such as natural selection and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations [3]
