Detailed explanation-1: -This map shows how a land bridge connected the continents of Asia and North America when the most recent ice age lowered sea levels.
Detailed explanation-2: -As of 2008, genetic findings suggest that a single population of modern humans migrated from southern Siberia toward the land mass known as the Bering Land Bridge as early as 30, 000 years ago, and crossed over to the Americas by 16, 500 years ago.
Detailed explanation-3: -In the 1970s, college students in archaeology such as myself learned that the first human beings to arrive in North America had come over a land bridge from Asia and Siberia approximately 13, 000 to 13, 500 years ago. These people, the first North Americans, were known collectively as Clovis people.
Detailed explanation-4: -It’s Anthropology 101. At the end of the last ice age, around 13, 000 years ago, retreating glaciers created an inland corridor connecting Siberia to the Americas. People from northeast Asia crossed the Bering Strait land bridge and entered a new world.
Detailed explanation-5: -The first definitive archaeological evidence we have for the presence of people beyond Beringia and interior Alaska comes from this time, about 13, 000 years ago. These people are called Paleoindians by archaeologists.
