Before Anyone Was There: How America's Geography Actually Formed

"Before Anyone Was There: How America's Geography Actually Formed Right now North and South America look like they've always been one connected landmass. They haven't. For millions of years, open ocean flowed freely between them through a gap called the Central American Seaway, where Panama sits today. This video breaks down how tectonic plates slowly collided over tens of millions of years to form a land bridge that didn't just connect two continents, it reshaped the entire planet. We explore how the closing of this ocean gap triggered the Great American Biotic Interchange, sending animals migrating in both directions for the first time in history, and how it may have redirected ocean currents strongly enough to help trigger the ice ages that followed. All of this happened long before any human ever set foot on this land.
