Question

"Human beings first arrived in the Americas approximately:

a. 50,000 yBP.
b. 25,000 yBP.
c. 15,000 yBP.
d. 5,000 yBP."

Answer 1

The earliest arrival of humans in the Americas was between 20,000 and 14,000 years ago, supported by the Bering Land Bridge and coastal migration theories. The Solutrean hypothesis of European descent is unlikely, according to genetic studies.

Step-by-step explanation:

The earliest arrival of humans in the Americas is believed to be between 20,000 and 14,000 years ago. This is supported by the two well-accepted theories of the Bering Land Bridge and coastal migration, which both suggest migration from Asia. The Solutrean hypothesis, proposing European descent, is unlikely according to genetic studies. The dating becomes less accurate as it goes further back in time, making the early dates before 20,000 years ago less conclusive.
