This chapter reviews evidence from research on the phylogenetics and phylogeography of Central American freshwater fishes, particularly in the Isthmus of Panama. It aims to address the question of the timing of the origins of the major taxonomic components of the fauna. It explains that the traditional interpretation of The Great American Biotic Interchange is inconsistent with the newly available phylogenetic and paleogeographic information on freshwater fishes and suggests that the prevailing view of a predominantly south-to-north faunal exchange starting about three million years ago that was the source of much of the current Central American ichthyofauna is an overly simplistic interpretation.
