Document Summary
Natural selection: the most critical mechanism of evolutionary changes, first articulated by charles. Darwin; refers to genetic change or changes in the frequencies of certain traits in population due to differential reproductive successes between species. Fixity of species: the notion that species, once created, can never really change; an idea diametrically opposed to theories of biological evolution. First person to recognize that groups of plants and animals could be distinguished from other groups by their ability to mate with one another and produce offspring. Placed such groups of reproductively isolated organims in a single category --> species. Species frequently shared similarities with other species --> genus. Carolus linnaeus (1707-1778): developing the method of classifying plants and animals. He included humans in his classifying of animals, placing them in the genus homo and species sapiens. Binomial nomenclature: in taxonomy, the convention established by carolus linnaeus whereby genus and species names are used to refer to species.
