Shortly after Europeans first came to the remote Pacific dominion they telephone Easter Island , a narrative arose around the people they found there . According to the story , the people had run through the island ’s resourcefulness , which push them into cannibalism and a serious population collapse , often referred to as ecological suicide . raw analysis of DNA from some of the island ’s historic residents tells a very unlike story .
Using radiocarbon geological dating and genome sequence , a enquiry team , which included J. Víctor Moreno - Mayar , a geneticist from the University of Copenhagen , reason that the population of Rapa Nui , as the island is now known , never experienced such a striking decline . The squad also found some surprising information about the ancestors of Rapa Nui ’s people , which could have a major impact on our apprehension of how how pre - colonization population mixed and interact .
late archaeological research had shown that Rapa Nui was first settle by Polynesian people around the yr 1250 CE . Over the next five 100 , the descendents of those people get what became have sex as the Rapanui culture , which is best have it away for the towering , stone - faced statues eff as Moai ( to be clear , “ Rapanui ” mention to the mass , whereas “ Rapa Nui ” refers to the island ) .

For many long time , the prevailing theory was that , as the island ’s population grew , eventually reaching a peak of around 15,000 , they disforest the island , leading to food for thought deficit . That lead in a population of just 3,000 by the time Europeans arrived . In late years , grounds has started to jump on that this was n’t the case , including depth psychology of cock used by the Rapanui that indicatea thriving societyin the timeframe of the suppose collapse .
The raw DNA analysis , publishedinNaturetoday , tot up further support to the grow counternarrative . They redo the genome using sample from 15 human remains , which carbon 14 geological dating suggest are from individuals who in all probability live before 1860 . Using that information , they were able to extrapolate how closely the citizenry of Rapa Nui were related across time . While there was a small reduction of universe in the meter period around the island ’s settlement , the grounds showed gradual ontogenesis across time . There was no population detonation , the scientist wrote . Rather , there was just firm maturation , from the first settlers until Europeans got there in 1722 .
The findings are the modish reverse to the narrative that , when Europeans first came to Rapa Nui , they “ found a poor community of interests with only a few people remain after overconsumption , violence and cannibalism during the 17th century , ” wrote Stephan Schiffels and Kathrin Nägele , both from the Max Planck Institute for Evolutionary Anthropology , in an accompanyingNews & Viewsarticle . “ The latest results join a growing amount of evidence that Rapa Nui could , in fact , sustain a large population despite environmental variety , with first historic explanation describing the island as ‘ earthly paradise . ’ ”
Schiffels and Nägele depict a comparison between the suppose collapse of Rapa Nui and manhood ’s current struggle with climate change . Rather than a tale of despair , they wrote , perhaps Rapa Nui could allow “ a promising write up about humans ’ resiliency and capacity to learn to superintend resources sustainably in the face of environmental changes . ”
Another finding presented in the new newspaper was just as surprising . late DNA analytic thinking of ancient Rapanui remains had n’t found any signs of aboriginal American genetics . Using the more comprehensive whole genome sequence , the geneticists found grounds that the Rapanui begin have baby with Native Americans some time between 1336 and 1402 — after their arriver on the island , and centuries before Europeans bugger off there . In total , around 10 % of the DNA could be delineate to mass indigenous to coastal South America .
What continue unclear is just how those the great unwashed from the American continent got there . Rapa Nui is over 1,180 miles ( 1,900 kilometre ) away from the nearest inhabited island , make it one of the most remote inhabited spot on the face of the major planet . Though technically a part of Chile , it ’s 2,290 Swedish mile ( 3,686 klick ) from the mainland .
One important caveat to the subject is how the research worker receive the sampling . The DNA was take from human remains that had been place to a Paris museum in the nineteenth century . That kind of colonial practice session is understandably worrisome and upsetting , and the anthropologist made sure to direct it in their workplace . In the sketch ’s text , they made it vindicated they work with Rapa Nui communities to get consent to analyze the human remains . In their analytic thinking , they come up the human stiff were tie in to modern sidereal day Rapanui , a finding they wrote will hopefully lead to the samples finally being repatriated .
