Although called a "bridge," the land was really a broad, grassy plain, which many animals stopped to feed on. Early Occupants With the emergence of the land bridge, early migration of animals and humans could have been made completely by land instead of water. Scientists are not positively sure how long ago the migration took place, but they believe between 10,000 and 25,000 years ago. This slow migration over thousands of years is what is believed to be responsible for the population of plants, animals and people to North and South America. Map "As one of the world's great ancient of B crossroads, Beringia may hold solutions to eri puzzles about who were the first people to ngia populate North America, how and when they traveled, and how they survived under such harsh climatic conditions." Beringia The term Beringia refers to the 1,000-mile long landmass that connected Asia and North America 10,000-25,000 years ago. During this time, glaciers up to two miles thick covered large parts of North America, Europe and Asia. The period was called the Pleistocene Ice Age.

The result was an intermittent land bridge stretching between the two continents under the present day Bering and Chukchi Seas. Scientists believe that Beringia was at its widest point about 15,000 years ago. Although called a "bridge," the land was really a broad, grassy plain, which many animals stopped to feed on. Animals such as wolves, bears, lions, woolly mammoths, bison, caribou, horses and antelope wandered and fed on the plain. Hunting groups followed game animals through the ice-free lowland areas not realizing they crossed over to a new continent. Without the presence of the land bridge these areas may not have been inhabited until much later. Over time, the massive ice sheets melted slowly raising water levels, covering up the shallow ocean floor. Evidence of the Existence of the Land Bridge What evidence exists? Example 1: Similarities between the peoples of Siberia and Alaska --similar language --shared spiritual practices --similar hunting tools --methods of food preservation Archaeological Sites Evidence of the Existence of the Land Bridge Evidence #2: Similarities of some plant species in Siberia and Alaska in the vicinity of the land bridge. Because of the large numbers of similar species, scientists hypothesize that the seeds of these plants could not have been disbursed by the wind and birds alone. Evidence #3: Fossil evidence that large land animals like the woolly mammoth, could not have simply swam across the Bering Sea. The distance is too long for most land mammals. A land bridge had to be in existence in order for so many of the same species to be present in such large numbers on both continents.

The Bering Strait connects the Bering Sea to the south with the Chukchi Sea to the north.
