The WEIRD Way Monkeys Got to America

From MinuteEarth.

Many of the greatest biological dispersal events in history likely happened because animals inadvertently traveled across the oceans on floating debris.

To learn more about this topic, start your googling with these keywords:
– Oceanic dispersal: A type of biological dispersal where terrestrial animals transfer from one land mass to another via a sea crossing.
– Rafting event: Oceanic dispersal that happens via floating vegetation.
– Platyrrhini: The so-called “New World Monkeys” that descended from African simians that arrived in South America roughly 30-40 million years ago.
– South Equatorial Current: A current maintained by the trade winds that flows westward along the equator.
