It was proposed by Darwin and Wallace, and it is the process by which organisms with favorable traits are more likely to survive and reproduce, driving the adaptation and evolution of species over time. Migration (gene flow) and small population (genetic drift) are also factors of evolution, but natural selection is more directly and famously tied to the core concept of evolution as it explains how species become adapted to their environments.
