	Land bridge - Wikipedia, the free encyclopedia
		The best-known is the Bering land bridge, which connected North Asia and Alaska during the last ice age, enabling humans to migrate from Eurasia to the Americas by walking.
		Land bridges generally occur on continental shelves: the Bering Strait, where the Bering Land Bridge was during the last glaciation, is part of the edge of the North American plate.
		A land bridge that rose from the sea floor because of upthrust at the edge of a continental plate is Central America.

	Bering land bridge - Wikipedia, the free encyclopedia
		The Bering land bridge, also known as Beringia, was a land bridge roughly 1600 km (1000 miles) north to south at its greatest extent, which joined present-day Alaska and eastern Siberia at various times during the ice ages.
		The Bering Strait, the Chukchi Sea to the north and the Bering Sea to the south, are all shallow seas.
		Land animals were able to migrate through Beringia as well, bringing mammals that evolved in Asia to North America, mammals such as lions and cheetahs, which evolved into now-extinct endemic North American species, and exporting camelids that evolved in North America (and later became extinct there) to Asia.

	BLB: Overview
		The Bering Land Bridge animation was created to assist with scientific research of environmental change, sea-level history, and the migration of humans, flora, and fauna into the Americas after the Last Glacial Maximum.
		The land bridge was an effective corridor for mammals (including large herbivores such as the wooly mammoth), other fauna, and flora to migrate east or west.
		Although a basic understanding of the land bridge is established, further research is needed to address such issues as: timing of sea-level rise and the creation of Bering Strait; human and animal migration into and from the New World; environmental and climate processes and feedbacks.

	Bering land bridge
		The Bering land bridge, also known as Beringia, was a land bridge roughly 1600 km (1000 miles) across, which is believed to have joined present-day Alaska and eastern Russia at various times during the ice ages.
		Other land bridges around the world have been created and re-flooded in the same way: between mainland Australia and Tasmania, for example, or between the islands of Indonesia.
		The Bering Land Bridge is significant for several reasons, notably because it may have enabled human migration to The Americas from Asia about 12,000 years ago.

	Yukon Beringia Interpretive Centre - Beringia Research Note
		The strait, Bering sea, the land bridge, and Bering Island were named for Vitus Jonassen Bering, a Danish explorer who served as an officer in the Russian navy.
		The Bering Land Bridge originated at least 70 million years ago (mya) and was a dry land route for the movements of plants and animals on many occasions.
		When the land bridge is submerged, Beringia forms a link between the Pacific and Arctic Oceans, allowing marine molluscs and other life forms to exchange between the ocean basins.

	New Study Confirms Bering Land Bridge Flooded Later Than Previously Believed
		A new study confirms the Bering land bridge that carried ancient wanderers from Asia into North America was not inundated by rising seas until about 11,000 years ago, according to a University of Colorado at Boulder researcher.
		The study also shows the Bering land bridge vegetation at the time consisted primarily of tundra plants and shrubs and was unsuitable for long-term habitation by large grazing mammals, said CU-Boulder researcher Scott Elias.
		The Bering land bridge surfaced during Earth's ice ages when sea level in the Bering Sea and Chukchi Sea dropped by 300 feet or more due to a buildup of glacial ice.

		For years, scientists envisioned the Bering land bridge as a dry grassland where mammoths and bison grazed, attracting hungry humans who may have migrated back and forth between what is now Alaska and Siberia.
		The Bering land bridge, thought by some scientists to be the pathway for the ancestors of all the Native people of North and South America, was a chunk of land more than twice the size of Texas, Elias said.
		The land bridge rose from the ocean thousands of years ago during the last ice age, Elias said, when sea level dropped dramatically as glaciers took up water in the form of ice.

		The bridge "rose" from the ocean as vast amounts of ocean water became tied up in the enormous glaciers of the last ice age.
		Their more accurate analysis showed that terrestrial plants and animals were living on the land bridge 11,000 years ago, meaning that the land bridge existed until after the oldest proven human settlements in the New World were started.
		There's now evidence that an ice shelf at the south of the land bridge may have been an ideal place for migrating, since the migrants would have had access to sea mammals and fish as they moved.

		This land bridge was created during the Ice Age when the receding water levels uncovered a massive expanse of land over 1,000 miles wide.
		Bering Strait, where the Eastern and Western Hemispheres face one another across a narrow strip of water, is the most likely place for migrating groups to have crossed into the New World.
		The prevailing theory calls for bands of interior hunters passing over the Bering Land Bridge, when sea levels were as much as 300 feet below at the end of the last Ice Age, and preceding through an "ice-free corridor" between the Laurentide and Cordilleran ice sheets to reach unglaciated lands to the south.
