Although there is still some debate around when exactly the Americas were first populated, it is now an accepted fact that the first colonizers came from Northeast Asia across the Bering Strait more than 15,000 years ago. From there, they began to populate the lands to the south, and by around 14,500 BCE were inhabiting encampments at Monte Verde. The unique conditions of the site have preserved some evidence, allowing us a window into how these early hunters adapted to the rainforest environment. After the extinction of the megafauna, the cornerstone of their early economy, these Paleo-Indian groups reoriented their hunting activities to new, smaller species, giving way to the Archaic Period.
