Explanations for biogeographic tracks across the Pacific Ocean: a challenge for paleogeography and historical biogeography

Authors(s) and Affiliation(s)



Amphi-Pacific organismal distributions form the ingredients of trans-Pacific biogeographic tracks, which may either be explained as the result of dispersal or vicariance. Under a vicariance paradigm the classical predrift reconstruction of Pangea cannot adequately explain trans-Pacific tracks. Alternative paleogeographic models that have been invoked as explanations for such tracks are discussed: the lost continent Pacifica, island integration, a new reconstruction of eastern Gondwanaland, and the expanding earth theory. None of these models is fully compatible with all geologic and biogeographic data available at present
