One of the most notable theories, the Ice-Free Corridor Hypothesis, posited that the first Americans entered from Asia via a passageway freed from glaciers. However, this theory has been increasingly questioned in light of new archaeological discoveries. Initially, sites like Mont Verde, located in Chile, were thought to be among the earliest evidence of human occupation in the Americas, dating back to roughly 13,000 to 14,000 years ago. Such findings posed a dilemma for archaeologists who were still wrestling with the idea that the first humans traveled through a northern corridor.
