Mystery surrounding ancient Easter Island people deepens

WASHINGTON (Reuters) – The massive brooding stone figures peering from Easter Island’s hillsides are emblematic of the enigmatic people who once thrived on the dot of land in the middle of the Pacific. New genetic research only deepens the mystery around these people.

Scientists said on Thursday an analysis of DNA from ancient skeletal remains ruled out the likelihood that Easter Island’s inhabitants intermixed with South Americans before the arrival of Europeans on the island in 1722.

A 2014 genetic study had indicated interbreeding between the people of Easter Island, or Rapa Nui, and native people in South America occurred roughly between 1300 and 1500. The new research, studying the DNA of three Rapa Nui people from the 1400s and 1500s and two from the 1800s, found no evidence of such mingling.

The research underscored the isolation of these people, who lived on an outpost some 2,300 miles (3,700 km) west of South America and 1,100 miles (1,770 km) from the nearest island.

“Our study shows that there is no simple scenario of population exchange and migration between Rapa Nui and the Americas as suggested by many archaeologists, historians, population geneticists and even adventurers,” said archaeologist Cat Jarman of the University of Bristol in Britain.

Jarman said the study, published in the journal Current Biology, confirmed a growing body of evidence that Easter Island was settled by Polynesians who crossed the open ocean.

“We were surprised that we didn’t find any Native American admixture in our ancient Rapa Nui individuals,” Jarman added.

The Rapa Nui people formed a unique culture best known for the 900 monumental head-and-torso stone statues known as moai erected around Easter Island. The culture flourished starting around 1200.

The study did not rule out some type of cultural contact between Easter Island and South America. “However, if it did take place, the new evidence suggests that it was infrequent or, at least, that it did not leave a…
