This is a very interesting find! Just goes to show how connected we all are, despite our current geological positions. Neat!

CAMBRIDGE, MASSACHUSETTS—A genetic study has revealed that the Tupí-speaking Suruí and Karitiana, and the Ge-speaking Xavante peoples of the Amazon had an ancestor more closely related to indigenous Australasians than other present-day populations.

“We’ve done a lot of sampling in East Asia and nobody looks like this. It’s an unknown group that doesn’t exist anymore,” Pontus Skoglund of Harvard Medical School said in a press release.


Despite being North American, I'm very unfamiliar about the origin of the people here (excluding the later European settlements of course). I knew that the American aboriginals were somehow related to ancient Asian ancestry, but that's about all I knew.

Skoglund and population geneticist David Reich have labeled this ancestor group Population Y, after the Tupí word for ancestor, “Ypykuéra.” They think that Population Y and the so-called First Americans, whose DNA resembles that of today’s Native Americans, traversed the Bering land bridge into North America more than 15,000 years ago. “We don’t know the order, the time separation or the geographical patterns,” Skoglund said. The team would need DNA from a member of Population Y to determine how much it contributed to today’s Amazonians. “We have a broad view of the deep origins of Native American ancestry, but within that diversity we know very little about the history of how those populations relate to each other,” Reich said.

I'm off to do some more research on the subject, as I am a bit too unknowable for my liking. If you'd like to join me, here's some more information!

Nearly one billion people today call the Americas home, inhabiting territories that stretch from the wide expanses of Canada and the United States, down through Mexico and Central America, and south through the varied landscapes of South America to Chile—from sparsely populated regions to some of the most crowded cities on the planet. And yet, as recently as 16,000 years ago, there may not have been anyone in these lands at all. Who were the earliest Americans, and how and when did they get here? These are questions that have long fascinated archaeologists and the public alike. As with all scientific endeavors, uncovering the story of how and when people arrived in the Americas will require an accumulation of evidence and data, and will long continue to be subject to revision. Here, then, is where the research has led so far:

Knowledge is power!
