saltation

saltation
Noun

This term is primarily used in technical, scientific registers across biology, geology, and zoology. It carries a connotation of abruptness and discontinuity, contrasting sharply with concepts of gradual change or smooth motion. In a biological context, it describes a "leap" in evolution, whereas in geology, it describes the physical bouncing of particles.

Because it is used as a technical term to describe a specific process or mechanism, it is typically treated as an uncountable noun. It is rarely pluralized unless referring to multiple distinct types or instances of the saltation process in a comparative scientific study.

Meanings

Nounsaltation

The action or process of leaping or jumping.

Nounsaltation

In geology, the movement of a particle such as sand or gravel that bounces along a stream bed or surface due to wind or water flow.

Nounsaltation

In evolutionary biology, a sudden, large-scale mutational change that produces a new species or a significantly different phenotype in a single generation.

The theory of saltation contrasts with the gradualism of Darwinian evolution.
