Polynesian DNA Study Reveals Strong Genetic Link Between Hawaiʻi and Easter Island
A new study on Polynesian DNA has revealed a surprising and strong genetic connection between the populations of Hawaiʻi and Rapa Nui (Easter Island), two of the most geographically distant islands settled by Polynesian voyagers. Despite being approximately 4,350 miles (7,000 kilometers) apart, their people are each other’s closest genetic relatives among remote island populations. The research, led in part by Keolu Fox, an associate professor of anthropology at the University of California San Diego, analyzed the complete DNA of 1,050 individuals from various Polynesian islands, including the Austral Islands, Society Islands, Marquesas, Tuamotu Archipelago, Mangareva, Samoa, and Tonga. The study found that the genetic link between Hawaiʻi and Rapa Nui was consistently stronger than with other islands, suggesting a shared history of long-distance voyaging, potentially rooted through Mangareva. This phenomenon, termed 'founder effect,' indicates that small groups of settlers carried a subset of the gene poo...
