New evidence upends contentious Easter Island theory, scientists say

Rapa Nui, also known as Easter Island, never experienced a ruinous population collapse, according to an analysis of ancient DNA from 15 former inhabitants of the remote island in the Pacific Ocean.
Rapa Nui, also known as Easter Island, never experienced a ruinous population collapse, according to an analysis of ancient DNA from 15 former inhabitants of the remote island in the Pacific Ocean.
The analysis also suggested that inhabitants of the island, which lies about 3,700 kilometres (2,300 miles) from the South American mainland, reached the Americas in the 1300s — long before Christopher Columbus’ 1492 landing in the New World.
Settled by Polynesian seafarers 800 years ago, Rapa Nui, today part of Chile, has hundreds of monumental stone heads that echo of the past. The island has long been a place of intrigue.
Some experts, such as geographer Jared Diamond in his 2005 book, “Collapse,” used Easter Island as a cautionary tale of how the exploitation of limited resources can result in catastrophic population decline, ecological devastation and the destruction of a society through infighting.
But that theory remains contentious, and other archaeological evidence suggests that Rapa Nui was home to a small but sustainable society.
The new analysis marks the first time scientists have used ancient DNA to address the question of whether Easter Island saw a self-inflicted societal collapse, helping to shed light on its mysterious past.
To investigate Rapa Nui’s history further, researchers sequenced the genomes of 15 former residents who lived on the island during the past 400 years. The remains are stored at the Musée de l’Homme, or Museum of Mankind, in Paris, which is part of the French National Museum of Natural History.
