The Siberian Land Bridge, also known as the Bering Land Bridge, was a land connection that existed during the last Ice Age, linking Asia and North America. This bridge allowed various species, including early humans, to migrate between the two continents. It was formed due to lower sea levels, which exposed land that is now submerged under the Bering Strait. The land bridge played a crucial role in the spread of flora and fauna, as well as human populations. As the climate warmed and ice melted, the bridge submerged, isolating the continents. This event significantly influenced the development of cultures and ecosystems in both regions.
