The real mystery behind Moana: After 1,700 years, why did Polynesians suddenly sail east?
New climate evidence adds context to these long voyages.
The same question drives both the plot of Moana and decades of archaeological research: Why, after centuries of relative stability, did Polynesian voyagers suddenly begin settling islands thousands of kilometers away across the Pacific?
The latest Moana movie is a live-action adaptation of a Disney animated movie of the same name. While the films are fictional, they draw inspiration from the rich seafaring heritage of Polynesian peoples, whose ancestors undertook one of the greatest episodes of maritime exploration in human history.
New climate evidence may help us understand why they embarked on these voyages.
