The core of Darwin's theory is natural selection, a process that occurs over successive generations and is defined as the differential reproduction of genotypes. Natural selection requires heritable variation in a given trait, and differential survival and reproduction associated with possession of that trait.
The basic mechanisms of evolution include natural selection, genetic drift and mutation. Natural selection is a process in which the population of organisms that have adapted to their environment increases more than the population of less well-adapted forms. This concept was first explained in Charles Darwin's theory of evolution.
