Darwin
Individual organisms differ, and some of this variation is due to heredity.
Organisms produce more offspring than can survive, and many that do survive do not reproduce.
Because more organisms are produced than can survive, they compete for limited resources.
Individuals best suited to their environment survive and reproduce most successfully and pass on their heritable traits to their offspring. This process of natural selection causes species to change over time.
Species alive today are descended with modification from common ancestral species that lived in the distant past.
