23 de abr. de 2024 · Evolution is the process of descent with modification that explains the origin and diversity of living things on Earth. Learn about the evidence, history, types, and examples of evolution from Britannica's experts.
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.

Biological evolution is the process of change and diversification of living things over time, and it affects all aspects of their lives—morphology (form and structure), physiology, behaviour, and ecology.
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.
