Panama's isthmus stays 3 million years young: Further evidence needed to support an older age

The formation of the tiny Isthmus of Panama had major geographic repercussions, cutting off the Caribbean Sea from the Pacific Ocean and connecting North and South America. A new study using multiple lines of geological, biological and molecular evidence supports the most commonly accepted age of the isthmus, about 3 million years, refuting a pair of 2015 studies that placed the closing at a much earlier date.

Benchmarks: October 10, 1913: Atlantic and Pacific waters meet in the Panama Canal

At that moment, more than 6,400 kilometers away, about seven metric tons of dynamite exploded, clearing the final obstruction in the Panama Canal. Deep within the Culebra Cut, waters from the Atlantic Ocean finally met waters from the Pacific Ocean, marking the end of major construction on the 77-kilometer-long canal.
