Glossary of "Biogeography (9th ed.)" by Cox et al. (2016)
- An approach to historical biogeography based on the assumption that related taxa, occupying ranges that are separate from one another, arrived in them before the appearance of the barriers that now separate them, rather than by dispersal across the barriers after they had formed.
