FIU: Geologist challenges age of land bridge connecting Americas

Despite the belief that the strip of land connecting North and South America is older than dirt, it is actually quite young.

After analyzing data from rocks, fossils and genetic studies, a team of international researchers found the land bridge, known as the Isthmus of Panama, formed 2.8 million years ago. This finding contradicts recent studies arguing the land bridge came together anywhere from 6 to 23 million years ago, and it offers insight about the evolution and migration of animals in the region.
