DNA evidence confirms pre-Columbian contact between South America and Polynesia. Easter Island contains DNA from South America South American populations contain Polynesian DNA DNA evidence proves contact between South American and Polynesian cultures

DNA now confirms what Thor Heyerdahl proposed decades ago: pre-Columbian contact between South America and Polynesia. Native American DNA has been found in Rapa Nui (Easter Island) and some other Polynesian populations; genetic studies show this contact occurred around 800 years ago, before European arrival. Once ridiculed, Heyerdahl's hypothesis of South American influence on Polynesian cultures now has genetic support, though researchers debate whether Polynesians traveled to South America and returned, or whether South Americans reached Polynesia.
