| saltatory evolution | The theory that evolution of a new species from an older one may occur as a large jump, such as a major repatterning of chromosomes, rather than by gradual accumulation of small steps or mutations. Compare: emergent evolution. (05 Mar 2000) |

| saltatory | Leaping or dancing; having the power of, or used in, leaping or dancing. <biology> Saltatory evolution, an affection in which pressure of the foot on a floor causes the patient to spring into the air, so as to make repeated involuntary motions of hopping and jumping. Origin: L. Saltatorius. See Saltant, and cf. Saltire. Source: Websters Dictionary (01 Mar 1998) |
|---|---|
| saltatory chorea | Rhythmic dancing movements, as in procursive chorea. (05 Mar 2000) |
| saltatory conduction | A method of neuronal transmission in vertebrate nerves, where only specialised nodes of Ranvier participate in excitation. This reduces the capacitance of the neuron, allowing much faster transmission. See: myelin, Schwann cells. (18 Nov 1997) |
| saltatory movement | Abrupt jumping movements of the sort shown by some intracellular particles. Mechanism unclear. (18 Nov 1997) |
| saltatory replication | The sudden amplification of a DNA sequence to generate many copies in a tandem arrangement. Possible mechanism for the origin of satellite DNA. (18 Nov 1997) |
| saltatory spasm | A spasmodic affection of the muscles of the lower extremities. Synonym: Bamberger's disease, dancing spasm, Gowers disease. (05 Mar 2000) |
| biologic evolution | Biologic evolution was contrasted with cultural evolution in 1968 by A.G. Motulsky who pointed out that biologic evolution is mediated by genes, shows a slow rate of change, employs random variation (mutations) and selection as agents of change, new variants are often harmful, these new variants are transmitted from parents to offspring, the mode of transmission is simple, complexity is achieved by the rare formation of new genes by chromosome duplication, biologic evolution occurs with all forms of life, and the biology of humans requires cultural evolution. See Cultural evolution. (12 Dec 1998) |
| chemical evolution | The theory of the process by which life arose from inorganic matter. (05 Mar 2000) |
| coincidental evolution | <molecular biology> The tendency for the same mutation to arise simultaneously in all copies of a gene which has been duplicated. (09 Oct 1997) |
| concerted evolution | The ability of two related genes to evolve together as though constituting a single locus. Synonym: coincidental evolution. (05 Mar 2000) |
| convergent evolution | The process where two unrelated structures in unrelated organisms evolve to perform similar functions. (The structures are called analogous structures.) For example: the wings of bats, birds, and insects evolved separately from each other but all are used to perform the function of flying. For another example: the complex eyes of vertebrates, cephalopods (squid and octopus), cubozoan jellyfish, and arthropods (insects, spiders, crustaceans) evolved separately, but all perform the function of vision. (09 Oct 1997) |
| cultural evolution | The continuous developmental process of a culture from simple to complex forms and from homogeneous to heterogeneous qualities. (12 Dec 1998) |
| spontaneous evolution | The unaided delivery of the foetus from a transverse lie. (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) |
| Denman's spontaneous evolution | A mechanism of spontaneous molding of the foetus and impaction of the shoulder with prolapse of the arm noted in some cases of transverse lie; vaginal delivery is achieved with the breech appearing at the vulva immediately after the prolapsed shoulder.
