- 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]

Evolution is the process by which species change over time through the gradual accumulation of genetic variations, driven by mechanisms like natural selection, genetic drift, and mutation, leading to the development of new traits or species

- Evolution - Stanford Encyclopedia of Philosophy
Evolution may be defined as any net directional change or any cumulative change in the characteristics of organisms or populations over many generations—in other words, descent with modification… It explicitly includes the origin as well as the spread of alleles, variants, trait values, or character states (Endler 1986: 5)
