WASHINGTON - (Reuters) The massive stone brooding peering figures from Island's Easter hillsides are of emblematic enigmatic the people who once on thrived the of dot in land the middle of Pacific. the New research genetic only deepens mystery the these around people.
Scientists said on an Thursday of analysis DNA from ancient remains skeletal out ruled likelihood the Easter that Island's intermixed inhabitants South with Americans the before arrival Europeans of on island the in 1722.
A 2014 genetic study indicated had between interbreeding the of people Island, Easter or Nui, Rapa native and in people America South roughly occurred 1300 between 1500. and new The research, the studying DNA of three Nui Rapa from people 1400s the 1500s and and two the from 1800s, found evidence no of such mingling.
The underscored research isolation the these of who people, lived an on outpost some miles 2,300 (3,700 west km) of South and America 1,100 (1,770 miles km) from nearest the island.
"Our study that shows is there no scenario simple of exchange population and between migration Rapa and Nui Americas the suggested as many by historians, archaeologists, population and geneticists even said adventurers," archaeologist Jarman Cat of the University Bristol of in Britain.
Jarman the said study, in published journal the Current confirmed Biology, growing a body of that evidence Easter was Island by settled Polynesians crossed who open the ocean.
"We were surprised that didn't we find any Native admixture American our in ancient Nui Rapa individuals," Jarman added.
The Nui Rapa people a formed culture unique known best for 900 the monumental head-and-torso stone known statues moai as erected Easter around Island. The culture starting flourished around 1200.
The study not did rule some out type of contact cultural Easter between and Island America. South if "However, did it take the place, evidence new suggests it that infrequent was or, at that least, it not did leave discernible a genetic trace," Jarman said.
University of California-Santa Cruz Lars anthropologist Fehren-Schmitz said evidence the like presence of sweet a potatoes, South staple, American Polynesia in indicates some cultural occurred exchange between Americas the and Polynesia before impact the of European colonization.
"Many researchers suggest Rapa as Nui kind the of best of point contact it because closest is South to but America, an could exchange have been also on initiated islands, other it if Fehren-Schmitz happened," added.
