How did the first people come to the Americas?

Answer 1

Research says that the first Americans came through Syberia. They travelled through continents on the Bering Strait on a land bridge that is now covered in water. There were two separate influxes- one 30,000 years ago and one 12,000 years ago.

Answer 3

At one time scientists were certain concerning the identity of the first people to come to the Americas. Now, some argument exists. The oldest theory is that in Siberia during the Ice Age, gaps opened in glaciers enabling people to live on the north side of the glaciers. Then people walked across land from Siberia to Alaska. At that time the oceans were much lower than today. Much of Alaska and Siberia was covered by Glaciers, but the top half of Alaska is desert. Not enough snow fell to produce a glacier. The same type of land existed across the Bearing Land Bridge in Siberia. When groups of hunters and gathers crossed across the Bearing Land Bridge, they went from one desert to another. They needed to keep moving. They kept moving south. When they came south, they settled the Americas.

Another theory is that people kept extending their fishing ranges. They had boats 50,000 years ago that could sail over 80 miles (40 there and 40 back across Wallace's line). As the boats from Asia kept going farther and farther away, they built fishing camps. When they came to the Americas, they built fishing camps. They carried their women with them. At some time, they ceased coming home to their base in Asia. So some may have come by sea.

There is also a place in Virginia where Europeans lived 20,000 years ago. These may have been fishermen blown off shore. If they did not have any women, the colony would have died when the fishermen died. We do not know if they had any survivors. One place only proves that people existed at one point in one place. It does not prove they stayed.

Answer 4

During the last ice age when the sea levels were much lower, a land bridge connected present day Russia with present day Alaska across the Bering Strait. The group of humans living in northern Asia at that time were able to cross this bridge into North America. As the ice age was ending and the ice was melting, the sea levels rose once again, covering the land bridge.
