The first humans who migrated to North America came on what?
Some historians believe the first humans in North America walked across a land bridge on what is now Bering Straits between northeastern Russia and Alaska. Other historians believe that the first humans followed the coast line and came on boats.
The first humans who migrated to North America are believed to have arrived around 20,000 years ago during the last Ice Age. They crossed over a land bridge known as Beringia, which connected present-day Siberia (Russia) to Alaska (United States). This land bridge was formed by lower sea levels due to the large amount of water trapped in glaciers, allowing early humans to walk across from Asia to North America.
The first humans who migrated to North America came on what is known as the Bering Land Bridge. To understand this, we need to look at some historical and geographical context.
During the last Ice Age, about 20,000 years ago, large parts of the Earth's water were locked up in glaciers, causing the sea level to drop significantly. This exposed a land bridge between what is now Siberia in Russia and Alaska in North America, connecting the continents. This land bridge is referred to as the Bering Land Bridge or Beringia.
Now, let's address the question directly. The first humans believed to have migrated to North America crossed this land bridge. They were likely nomadic hunter-gatherer groups originating from Asia, specifically northeastern Siberia. These ancient humans, known as the Paleo-Indians, would have walked across the Bering Land Bridge and gradually dispersed into different regions of North America as the ice retreated and the sea levels rose again, around 12,000 to 13,000 years ago.
It's important to note that although the Bering Land Bridge provided the initial pathway for human migration into North America, subsequent migrations and movement of people also occurred through various other routes and means.
