Charles Darwin was a British biologist who postulated the natural selection hypothesis of biological evolution.
"Descent with modification," as Darwin defined it, is the theory that species change over time, give rise to new species, and share a common ancestor.
Natural selection is the mechanism hypothesized by Darwin for evolution. Because natural resources are finite, organisms with heritable features that benefit survival and reproduction will tend to leave more offspring than their contemporaries, increasing the frequency of the traits over generations.
Natural selection causes populations to adapt to their environments over time, or become increasingly well-suited to them. Natural selection is influenced by the environment and necessitates the presence of heritable variation within a group.
