Evolution is the change in the heritable characteristics of biological populations over successive generations. 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.

19 de oct. de 2023 · Learn about the theory of evolution by natural selection, a scientific explanation of how organisms change over time. Find out the history, ideas, and examples of this concept, as well as its relation to other mechanisms of evolution such as genetic drift and survival of the fittest.
Hence, in genetic terms evolution consists of changes in the organism’s hereditary makeup. Evolution can be seen as a two-step process. First, hereditary variation takes place; second, selection is made of those genetic variants that will be passed on most effectively to the following generations.
Evolution is the flagship journal of the Society for the Study of Evolution, publishing articles on evolutionary phenomena and processes at all levels of biological organisation. Find out more about the journal, its editorial board, latest issue, virtual issues, and related resources from SSE.
