Abstract: South America was the last habitable continent to be colonized by humans; using a database of 1,147 archaeological sites and 5,464 radiocarbon dates spanning 14,000 to 2,000 years ago reveals two phases of the population history of the continent—a rapid expansion through the continent at low population sizes for over 8,000 years and then a second phase of sedentary lifestyle and exponential population growth starting around 5,000 years ago.
