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

Historical biogeography of the Isthmus of Panama.

TL;DR: As a sea barrier, the isthmus induced divergent environmental change off its two coasts—creating contrasting ecosystems through differential extinction and diversification.
Journal ArticleDOI
