The Megafauna of the Americas Have Vanished Into History. Our Ancestors Are to Blame.

The sudden disappearance of massive prehistoric animals like mammoths and saber-toothed cats across the Americas points to a major role played by early human settlers. Evidence suggests that as soon as humans arrived, they began to hunt these megafauna to the point of extinction, likely due to overhunting and changes in habitat. This discovery highlights the significant impact human activity can have on large ecosystems, raising questions about our modern responsibility to protect biodiversity. It also underscores the importance of understanding our historical role in environmental changes.
