| analogous structures | outwardly similar structures but nonhomologous |
| artifical selection | breeding of domestic plants and animals to produce specific desirable features. |
| catastrophism | theory that a vast supply of species was created initially |
| convergent evolution | natural selection causes nonhomologous structures that serve similar functions to resemble one another |
| evolution | change over time in the characteristics of populations |
| fossil | rocks that wind, water, or people had worked into lifelike forms. |
| homologous structures | these have the same evolutionary origin despite any differences in current function or appearance |
| inheritance of acquired charactertistics | process in which the bodies of living organisms are modified through the use or disuse of parts, and these modifications are inherited by offspring |
| natural selection | individuals with advantageous traits survive longest and leave the most offspring |
| popluation | all the individuals of one species in a particular area |
| uniformitarianism | layers of rock are evidence of ordinary natural processes, occurring repeatedly over long periods of time |
| vestigial structure | serve no apparent purpose |
| Ladder of Nature | Aristotle's view, fixed, unchanging species could be arranged in an order |
| Charles Darwin | Published work on evolution |
| George Louis LeClere | French naturalist that suggested the original creation provided a small number of species conceived by nature |
| George Cuvier | French paleontologist who hypothesized about the catastrophism theory |
