31964335 | taxonomy | Branch of biology concerned with identifying, describing, and naming organisms. | |
31964336 | paleontology | Study of fossils that results in knowledge about the history of life. | |
31964337 | natural selection | Mechanism of evolution caused by environmental selection of organisms most fit to reproduce; results in adaptation to the environment. | |
31964338 | fossil record | History of life recorded from remains from the past. | |
31964339 | comparative anatomy | the study of anatomical features of animals of different species in order to determine either current or ancestral relationships | |
31965081 | gene pool | Total of all the genes of all the individuals in a population. | |
31965082 | directional selection | Outcome of natural selection in which an extreme phenotype is favored, usually in a changing environment. | |
31965083 | stabilizing selection | Outcome of natural selection in which extreme phenotypes are eliminated and the average phenotype is conserved. | |
31965084 | phyletic evolution | Genetic changes that occur within an evolutionary line that eventually cause one species to split into two species | |
31965085 | punctuated equilibrium | a theory of evolution holding that evolutionary change in the fossil record came quickly due to major environmental events rather than in a steady process of slow change; the opposite of gradualism. | |
31965086 | gradualism | A view of evolution that attributes profound change to the cumulative product of slow but continuous change that is passed on from parents to offspring over many generations. | |
31965558 | geographic isolation | separation of populations as a result of geographic change or migration to geographically isolated places | |
31965559 | reproductive isolation | separation of species or populations so that they cannot interbreed and produce fertile offspring | |
31965560 | adaptive radiation | Evolution of several species from a common ancestor into new ecological or geographical zones. |
