Formation of the Isthmus of Panama

TL;DR: An exhaustive review and reanalysis of geological, paleontological, and molecular records converge upon a cohesive narrative of gradually emerging land and constricting seaways, with formation of the Isthmus of Panama sensu stricto around 2.8 Ma.
Journal ArticleDOI

Measuring Past Biodiversity
