What was the Beringea Land Bridge?

The Beringea Land Bridge, often referred to as Beringia, was a land connection that existed during the last Ice Age, approximately 20,000 to 30,000 years ago, between present-day Alaska in North America and Siberia in Asia. This land bridge allowed humans and various animal species to migrate between the continents as sea levels were significantly lower due to glacial ice. As the climate warmed and glaciers melted, rising sea levels submerged the land bridge, isolating the populations that had crossed it. Beringia is crucial for understanding the migration patterns of early humans into the Americas.
