USA HISTORY

Detailed explanation-1: -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-2: -The earliest populations in the Americas, before roughly 10, 000 years ago, are known as Paleo-Indians.

Detailed explanation-3: -In Brief. For decades archaeologists thought the first Americans were the Clovis people, who were said to have reached the New World some 13, 000 years ago from northern Asia. But fresh archaeological finds have established that humans reached the Americas thousands of years before that.

Detailed explanation-4: -Right now we can solidly say that people were across the Americas by 15, 000 years ago. But that means people were probably already well in place by then; and there’s enough evidence to suggest humans were widespread 20, 000 years ago.
