Several ideas exist about the origins of early people in the Americas. Today we explored the Bering Land Bridge Theory, the Atlantic Theory, the Oceania Theory as to how early people arrived in the Americas. The most evidence available makes the arrival of people across the Bering Land Bridge almost definite. There is also good evidence for the Atlantic Theory and Oceania Theory as well, but the evidence is far thinner. Many other theories exist, but what we know for sure is that thousands of years ago, people migrated from other continents to the Americas. Jaydn took a comprehension quiz at the end of class.
