- 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 – Definition, Types, Advantages, Examples
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 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

In biology, evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection The theory of evolution is based on the idea that all species are related and gradually change over time
