Saltation (Biology) (Paperback)

High Quality Content by WIKIPEDIA articles 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 occasionally hypothesized, nongradual changes (especially single-step speciation) that are atypical of, or violate, standard concepts - gradualism - involved in neo-Darwinian evolution.
