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.
Natural selection is one of the mechanisms of evolution. Natural selection is the process in which individuals whom are better suited to their environment will have an increase fitness. For example, if we have a population of mice and some mice are brown and some mice are white, they express different traits.
