Question

The earliest Americans are known to have arrived in the Americas no later than:
A) 45,000 ya.
B) 30,000 ya.
C) 20,000 ya.
D) 13,000 ya.
E) 8,000 ya.

Accepted Answer

The most widely accepted theory suggests that the earliest Americans arrived via the Bering land bridge around 13,000 years ago, during the last Ice Age when sea levels were lower and the bridge still existed. While some evidence suggests that humans may have arrived in the Americas as early as 20,000-30,000 years ago, the evidence is debated and not widely accepted by the scientific community. The earliest undisputed evidence of humans in the Americas dates back to around 13,000 years ago.
