Scholars believe that the first people in North America reached the continent by C) walking across land from Asia. This theory is known as the "Bering Land Bridge" or the "Beringia Hypothesis." According to this hypothesis, it is believed that during the last Ice Age, sea levels dropped, exposing a land bridge called Beringia that connected Asia and North America. It is suspected that early humans migrated across this land bridge around 20,000 to 30,000 years ago.
