Question

How did the "first Americans" migrate to North America?

Answer 1

Traditionally, Native Americans are believed to have descended from northeast Asia, arriving over a land bridge between Siberia and Alaska some 12,000 years ago and then migrating across North and South America.

Answer 2

Scientists believe that the first people to live in America (the ancestors of the Native Americans) arrived to North America from Asia. They crossed a land bridge that is known as Beringia, located in the Bering Strait. This bridge was a consequence of lower ocean levels due to glaciers locking large amounts of water when the Earth was much colder.
