Question

Some scientists theorize that the nomadic hunters from Asia crossed the land bridge into North America for what reason?

Answer 1

C. They were searching for warmer weather. The most obvious reason is that one has to pack up and go because things are not so good at home. Long ago, that probably meant that the climate had changed and made life impossible. It might have become too hot or too cold or too wet, which in turn would have affected not only quality of life but also make survival a shaky proposition. Drought, flood, and temperature changes could certainly push people to move on.

Answer 2

Answer:

Option: B.) They were following herds of large mammals, such as mammoths and bison.

Explanation:

According to some scientist, the nomadic hunters might have moved to North America after following the herds of mammals, like Mammoth, Mastodons (now extinct) and Bison. The Nomadic hunters or people immigrated to the new land through Bering Land Bridge that connects Asia to America in about 12000 years ago.
