natural selection changes allele frequencies in a way that leads to adaptation to the environment fitness is the ability of an organism to compete successfully in passing its alleles on to the next generation (in a vessel that can continue that process) populations undergoing natural selection are evolving, with alleles survive.

Darwin’s Theory of Natural Selection occurs in four steps: Overproduction. best traits / adaptations will survive and have the opportunity to pass on it’s traits. Competition.
