Question

How did Homo sapiens reach North America from Africa? - They went through Europe and sailed west into Greenland. - They sailed from the southern tip of Africa to South America. - They went through Asia and crossed a land bridge into North America. - They sailed from the west coast of Africa to the east coast of North America.

Answer 1

Homo sapiens reached North America by migrating across the land bridge called Beringia during the last glaciation period.

Step-by-step explanation:

The first Homo sapiens reached North America from Africa by migrating across a land bridge called Beringia, which connected modern-day Alaska and Russia during the last glaciation period. This land bridge emerged around 18,000 years ago when sea levels were lower. Homo sapiens likely lived in Beringia for thousands of years before venturing into North America.

For a long time, the accepted account had been that, after anatomically modern humans dispersed from Africa into Europe and Asia, groups of hunters entered North America from Siberia at the end of the last ice age around 13,500 years ago, using a land bridge across the Bering Strait.

The western coastline of North America was ice-free thousands of years earlier than the interior. The pre-Clovis humans could have crossed the Bering Land Bridge on foot, then used simple boats to skirt around the glaciers and make their way down the West Coast of North and South America.
