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.

The theory of evolution is one of the fundamental keystones of modern biological theory.
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.

Jun 8, 2024 · human evolution, the process by which human beings developed on Earth from now-extinct primates. Viewed zoologically, we humans are Homo sapiens, a culture -bearing upright-walking species that lives on the ground and very likely first evolved in Africa about 315,000 years ago.
