Evolution, theory in biology postulating that the various types of living things on Earth have their origin in other preexisting types and that the distinguishable differences are due to modifications in successive generations The theory of evolution is one of the fundamental keystones of modern biological theory
- 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]
- An introduction to evolution
The definition Biological evolution, simply put, is descent with inherited modification This definition encompasses everything from small-scale evolution (for example, changes in the frequency of different gene versions in a population from one generation to the next) to large-scale evolution (for example, the descent of different species from a shared ancestor over many generations
