The Bering Land Bridge was a land connection that existed during the last Ice Age, linking present-day Alaska in the United States to Siberia in Russia. This bridge allowed humans and animals to migrate between North America and Asia when sea levels were lower, exposing the land. As the climate warmed and ice melted, the bridge submerged, creating the Bering Strait. This event significantly impacted the movement of species and the spread of human populations, contributing to the peopling of the Americas. Today, the area is studied for its importance in understanding ancient migration patterns.
