Natural selection is defined as individuals that have certain inherited traits tend to survive and reproduce at higher rates because of these traits. Competition between organisms is a factor in natural selection.

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
