| darwinian | Pertaining to Darwin; as, the Darwinian theory, a theory of the manner and cause of the supposed development of living things from certain original forms or elements. This theory was put forth by Darwin in 1859 in a work entitled "The Origin of species by Means of Natural Selection." The author argues that, in the struggle for existence, those plants and creatures best fitted to the requirements of the situation in which they are placed are the ones that will live; in other words, that Nature selects those which are survive. This is the theory of natural selection or the survival of the fillest. He also argues that natural selection is capable of modifying and producing organisms fit for their circumstances. See Development theory, under Development. Origin: From the name of Charles Darwin, an English scientist. Source: Websters Dictionary (01 Mar 1998) |

| darwinian ear | An auricle in which the upper border is not rolled over to form the helix, but projects upward as a flat, sharp edge. (05 Mar 2000) |
| Darwinian evolution | The proposition that the phylogeny of all species is wholly ascribable to the combined effects of random variation (mutation) in genotypes of the members of a stock as a result of the operation of undirected accidents with consequences to their phenotypes and the operation of preferential (but by no means certain) survival of those resulting phenotypes most suited to survive in the contemporary environment. The proposed system survives largely because of genetic factors that avidly conserve the ontogeny of the stock. (05 Mar 2000) |
| darwinian reflex | The tendency of young infants to grasp a bar and hang suspended. Compare: grasping reflex. (05 Mar 2000) |
| darwinian theory | The theory of the origin of species and of the development of higher organisms from lower forms through natural selection (survival of the fittest in the struggle for existence), and of the evolution of humans from an ancestor common to himself and the apes. (05 Mar 2000) |
