DNA Offers A New Look At How Polynesia Was Settled by Bruce Bower

Voyagers migrated to islands sprinkled across a large area of the Pacific within about 500 years. Polynesian voyagers settled islands across a vast expanse of the Pacific Ocean within about 500 years, leaving a genetic trail of the routes that the travelers took, scientists say. Comparisons of present-day Polynesians’ DNA indicate that sea journeys launched from Samoa in western Polynesia headed south and then east, reaching Rarotonga in the Cook Islands by around the year 830. From the mid-1100s to the mid-1300s, people who had traveled farther east to a string of small islands called the Tuamotus fanned out to settle Rapa Nui, also known as Easter Island, and several other islands separated by thousands of kilometers on Polynesia’s eastern edge. On each of those islands, the Tuamotu travelers built massive stone statues like the ones Easter Island is famed for.
