Definition of saltation in English:

saltation

noun sɒlˈteɪʃ(ə)nsalˈteɪʃ(ə)nsɔːlˈteɪʃ(ə)nˌsɔlˈteɪʃən

mass noun

1Biology
Abrupt evolutionary change; sudden large-scale mutation.
new genetic characters appear suddenly by saltation
count noun a new concept of evolution by saltations or sudden transitions
Example sentencesExamples
- He gave examples of new races formed in sudden jumps or saltations to illustrate that ‘the evolution of organisms may… be a much more rapid process than Darwin believes.’
- In a phylogenetic dendrogram, branches and twigs here and there show saltations into a new grade.
- In particular, where Darwin had seen evolution and a slow, gradual, continuous process, Huxley thought that an evolving lineage might make rapid jumps, or saltations.
- But accepting the data at face value raises the interesting possibility that hierarchy may be quite labile, that hierarchical saltations may be relatively easy in evolution.
- Lyons next examines Huxley's conversion from saltation to gradualism, predicated to a great degree on his own studies of Archaeopteryx and relationships among reptiles, dinosaurs, and birds.
2Geology
The transport of hard particles over an uneven surface in a turbulent flow of air or water.
the distance travelled by each grain during saltation
Example sentencesExamples
- Eroded sediment can be transported by creep, saltation, or suspension, and where much fine soil or sediment is present, dust clouds can result.
- Although the dunes near Parker seem to be an extension of this same sandflow path, Muhs says that saltation couldn't carry grains of sand across the Colorado River.
- Atreya then went on to show that substantially greater quantities of H2O2 can be produced by triboelectric fields in dust devils and dust storms and through saltation.
- This process, in which sand grains bounce downwind, is called saltation.
3archaic The action of leaping or dancing.
Example sentencesExamples
- In addition to the dorso-ventral flexion seen during saltation, the sacroiliac joint often allows varying degrees of lateral movement.
- These actions are important in the effective use of the hindlimbs during terrestrial saltation and swimming.
Synonyms
leap, jump, bound, vault, hop

Derivatives

saltatory

adjective ˈsaltət(ə)riˈsɒltət(ə)riˈsɔːltət(ə)ri

The saltatory nature of this type of flight results in extreme linear and angular displacements of the bird's body; however, birds isolate their heads from these accelerations with cervical reflexes.
Example sentencesExamples
- His intriguing take on evolution proposed that the apparent saltation of the fossil record actually reflected saltatory events.
- The species possesses paired, elongate lateral spines that function in saltatory sweeping motions in response to sheer disturbances by predators.
- The cytoskeleton is involved in the saltatory movement of organelles such as mitochondria or in the fusion of endosomes with primary lysosomes.
- The myelin acts as a layer of high electrical resistance and low capacitance, facilitating the rapid saltatory conduction of electrical impulses from node to node for long distances along axons that may be up to 1 m in length.

Origin

Early 17th century (in sense 3): from Latin saltatio(n-), from saltare 'to dance', frequentative of salire 'to leap'.
