Abstract
The article outlines the study conducted by Jon Erlandson, Michael Waters and colleagues on the movement of people from North to South America. Researchers excavated at the southern Chilean site of Monte Verde and they discovered that it contains evidences of long-term occupation such as huts, tents and hearths and was radiocarbon-dated to 14,200 to 14,600 years ago. Based on the information gathered, they concluded that the site has been pivotal to claims that humans arrived in the Americas before the 13,000-year-old Clovis culture. They also uncovered remains of nine species of marine algae plus three stone tools.
