Approximately 12,000 years ago, Paleoamericans traveled across the massive land bridge connecting Asia and North America, Beringia. This migration led to settlements in North America until Europeans started colonizing the land. The Natives, who had thousands of years of knowledge of the land, farming and hunting, helped the Europeans survive and let their colonies prosper. But what if higher temperatures 12,000 years ago caused Beringia to melt before the Paleoamericans ever crossed it? What if there was No Native America?
