GAARlandia

Animal and plant species are hypothesized to have colonized the Antilles by walking from South America over a lost land bridge.

The Greater Antilles + Aves Ridge,^[1] also known as GAARlandia, is a hypothesized land bridge which is proposed to have connected the Greater Antilles to South America around 33 million years ago (mya). Animal and plant species are thought to have colonized the Caribbean Islands through dispersal and vicariance, and the most prominent vicariance hypothesis involves colonization via GAARlandia. Proponents of the hypothesis cite studies of individual lineages, while critics point to a lack of geological evidence.
