Evolution - Wikipedia
WEBEvolution 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.

WEBEvolution 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.

WEBEvolution is the way that living things change over time. The first person who explained how evolution happens was Charles Darwin with his scientific theory of natural selection.

WEBBiological 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. Underlying these changes are changes in the hereditary materials.
Evolution (article) | Khan Academy
WEBEvolution is the change in inherited traits that occurs in a group of organisms over multiple generations. Inherited traits are those that are passed from parents to offspring via genes. Evolution is made possible by genetic variation , or gene differences, in a population.

WEBEvolution is the principal scientific theory that biologists use to understand life and is used in many disciplines, including medicine, psychology, conservation biology, anthropology, forensics, agriculture and other social-cultural applications.
