A new genetic study suggests that Polynesians made an epic voyage to South America 800 years ago. Scientists examined the DNA from 807 people from 14 Polynesian islands and Pacific coastal native American Populations from Mexico to Chile and found they had shared ancestry. Interpretations of the study have sparked debate between anthropologists and geneticists around its engagement with historical literature and the ethical context in which the DNA samples were taken. Population Geneticist Alexander Ioannidis from Stanford University says the evidence strongly suggests it was the Polynesians who voyaged to South America taking South Americans back out to sea with them - as opposed to the other way around.
