Beringia and Its Impact on Species Migration

The video explains how glaciers trapped water, lowering sea levels and forming the Beringia land bridge between North America and Siberia. This bridge allowed species like mammoths and early humans to migrate between continents. Beringia existed during various glacial and interglacial periods over the last 2 million years, with significant changes occurring around 22,000 to 6,000 years ago.
