North America
The first known migration to North America occurred in prehistoric times, from Asia. The European migration began in the 16th Century.
The land bridge was called Beringia. It connected present-day Siberia in Russia with Alaska in the United States, allowing for human migration between Asia and North America.
The Bering Strait which is between Asia and North America
Asia and North America are separate continents, so Asia is not in North America.
If you go back thousands of years it would be the people's who came from Asia.
Some scholars think that people migrated from Asia to North America during the ice age because the Bering Strait (the narrow body of water between Asia and North America) during the ice age became shallower which made the land underwater uncovered which formed a bridge between Asia and North America.
Access to North America was no longer possible on foot.
Europe, Asia, North America
During the last Ice Age, North America and Asia were connected by a land bridge known as Beringia. This connection facilitated the migration of humans and animals between the two continents.
The Beringia land bridge connected the continents of Asia and North America during the last Ice Age, allowing for human migration between the two regions.
During the many warm, (interglacial), periods in the present ice age it would have been impossible for humans to travel from Asia to North America. Only during glaciations would sea level drop enough to allow migrations from one continent to the other on dry land across, what is now, the Bering Strait.
