Saltation (biology)

In biology, saltation (from Latin, saltus, ""leap"") is a sudden change from one generation to the next, that is large, or very large, in comparison with the usual variation of an organism. The term is used for nongradual changes (especially single-step speciation) that are atypical of, or violate gradualism - involved in modern evolutionary theory.
