Beringia, Bering Land Bridge

Reference work entry
Beringia, Bering Land Bridge – in archeology and paleogeography, the name of a land bridge which used to connect the territories of the Eurasian (Chukotka) and American (Alaska) continents. It was 2,000 km wide from north to south. During the previous three million years, the territory of B. rose and sank as a result of general rise in the World Ocean level at least six times. The last time the continents separated was about 10–11 thousand years ago, but the land bridge had existed for 15–18 thousand years before this. Scientists believe that B. used to serve a natural bridge which facilitated the colonization of the American continent. The concept of B. was more fully defined by an American scientist D.M. Hopkins. B. is a part of Beringida.
