Definition

  • [Henderson's] the process by which evolutionary change is chiefly driven according to Darwin’s theory of evolution. Environmental factors such as climate, disease, competition from other organisms, and availability of certain types of food will lead to the preferential survival and reproduction of those members of a popu­lation genetically best fitted to deal with them. Continued selection will therefore lead to certain genes becoming more common in subsequent generations. Such selection, operating over very long periods of time is believed to be able to give rise to the considerable differences now seen between different organisms.
