Quizplus · Accepted Answer

Recent archaeological findings suggest that humans may have been migrating to the Americas as early as 30,000 years ago, which is much earlier than previously thought.

Answer: B 
 While there may have been other possible avenues of migration, such as along the Pacific coast or across the Atlantic, the Bering land bridge is the most widely accepted theory for the earliest migrations to the Americas.

Answer: C 
 It is possible that changes in climate, such as the end of the Last Glacial Maximum, may have played a role in driving native populations to migrate from Asia to the Americas.

Answer: D 
 There is no evidence to suggest that ancient Asians developed advanced sailing vessels that would have allowed them to cross the Pacific Ocean.

Answer: E 
 There is no evidence to support this theory, as it is not known why ancient Asian societies would have driven out populations to settle in the Americas.
