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.

Scitable provides an overview of evolution, genetics, and biodiversity, and how they shape ecology. Explore the mechanisms, examples, and applications of microevolution and macroevolution, and the role of molecular techniques in studying evolution.
3 days ago · Evolution - Natural Selection, Adaptation, Genetics: The central argument of Darwin’s theory of evolution starts with the existence of hereditary variation. Experience with animal and plant breeding had demonstrated to Darwin that variations can be developed that are “useful to man.”
