- 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, 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

- 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
- EVOLUTION Definition Meaning - Merriam-Webster
The meaning of EVOLUTION is descent with modification from preexisting species : cumulative inherited change in a population of organisms through time leading to the appearance of new forms : the process by which new species or populations of living things develop from preexisting forms through successive generations; also : the scientific theory explaining the appearance of new species and

Evolution is a process that results in changes in the genetic content of a population over time There are two general classes of evolutionary change: microevolution and macroevolution
- Evolution - Stanford Encyclopedia of Philosophy
Evolution in its contemporary meaning in biology typically refers to the changes in the proportions of biological types in a population over time (see the entries on evolutionary thought before Darwin and Darwin: from to for earlier meanings) As evolution is too large of a topic to address thoroughly in one entry, the primary goal of this entry is to serve as a broad overview of contemporary
