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: -Evidence based on human remains supports the idea that Native American expansion happened 16, 000 years ago, since the “earliest securely dated sites [are about] 15, 000 years ago."

Detailed explanation-3: -The settlement of the Americas began when Paleolithic hunter-gatherers entered North America from the North Asian Mammoth steppe via the Beringia land bridge, which had formed between northeastern Siberia and western Alaska due to the lowering of sea level during the Last Glacial Maximum (26, 000 to 19, 000 years ago).

Detailed explanation-4: -The dominant story in archaeology has long been that humans came to North America around 12, 000 years ago. But Indigenous archaeologist Paulette Steeves points to mounting evidence suggesting human migration may have occurred closer to 130, 000 ago.
