A massive genomic study analyzed Indigenous American populations and revealed evidence of a previously unknown human migration into South America, dating back as recently as 720 AD. These new genetic traces show similarities to populations found in Australia and the Pacific Islands.

A massive genomic study of Indigenous peoples in the Americas has uncovered evidence of a previously unknown migration into South America that occurred as recently as 1,300 years ago – during China’s Tang dynasty. These new settlers carried genes remarkably similar to Indigenous populations in what is now Australia and the Pacific Islands, according to the study published online by the journal Nature on April 22. The international team, which included scientists from the University of Sao Paulo....
