Question

About how long ago did humans arrive in the americas?a. 15,000 yearsb. 100,000 yearsc. 1,500 yearsd. 50,000 years

Answer 1

The correct answer is A.

The human race was not originated in America. The first settlers were nomadic people from the Paleolithic era, who arrived in the continent approximately 15,000 years ago using the Beringia land bridge. This crossing was possible because the sea level had decreased abruptly after the Last Glacial Maximum. Today this piece of land has become the Bearing Strait, separating Siberia (Rusia) and Alaska (US).
