The geological collision that rewrote the rules of evolution
In short: When continents move, they do more than reshape mountains; they rearrange the tree of life. This video explores how a massive tectonic shift created a biological bridge between two worlds.
Tens of millions of years ago, plate tectonics forced North and South America into an unavoidable collision. This geological event triggered the Great American Biotic Interchange, one of history's most significant episodes of biological migration.
The meeting of these landmasses fundamentally altered the face of the Earth, creating a corridor that allowed species from both continents to migrate into new territories. For thousands of species, this shift was a pivotal moment that determined their survival or extinction.
