- n. A leaping or jumping.
- n. Beating or palpitation.

from The Century Dictionary and Cyclopedia
- n. Saltatory action; the act or movement of leaping, or effecting a saltus; a leap or jump; hence, abrupt transition or change.
- n. Jumping movement; beating or palpitation.
- n. The name ‘saltation,’ or in recent years ‘mutation, has been applied to extreme fluctuation, the immediate cause of which is unknown. The experiments of Dr. Hugo de Vries on the saltations of the descendants of an American form of evening primrose (Œnothera lamarckiana) have recently drawn general attention again to the possibility that saltation has had a large part in the process of formation of species.

One of the primary indications that the RNA signatures are, in fact, remnants of an evolutionary saltation is their discrete character.
Alan Fox: If you are using "saltation" in its commonly understood meaning (with Goldschmidt as its premier proponent), I don't think you will find any current evolutionary biologist allowing it as a possibility.

Darwin never said that there would be a transformation of one species into another in one generation, and no evolutionist now claims this it's known as "saltation", and is discreditied.
Due to the process of wind-loom movement of dunes ( "saltation"), dune sands fall within a narrow range of particle size.
The term "saltation" implies large leaps, such as sudden speciation.
The focus on “large amounts of specified information” my emphasis also reduces his entire book to a strawman argument, since the TOE neither predicts nor expects saltation.
This is called “saltation” Google it, and results in many examples of self-organized patterns - most commonly in deserts and snow fields by the wind, and in shallow sandy bottoms, where the moving fluid is water in slow regular wave or tidal oscillation.
The paper specifically rejects typogenetic saltation.
No. I am just giving an example of a (former) evolutionary biologist who doesn't allow the possibility of saltation.
