Studies Find Genetic Signature of Native Australians In the Americas

Jul 23

Applehu Akbar writes: Two new research papers claim to have found an Australo-Melanesian DNA signal in the genetic makeup of Native Americans, dating to about the time of the last glacial maximum. This may move the speculation around the Clovis people and Kennewick man to an entirely new level. Let’s hope that it at least shakes loose some more funding for North American archaeology. Ars reports: “The exact process by which humanity introduced itself to the Americas has always been controversial. While there’s general agreement on the most important migration—across the Bering land bridge at the end of the last ice age—there’s a lot of arguing over the details. Now, two new papers clarify some of the bigger picture but also introduce a new wrinkle: there’s DNA from the distant Pacific floating around in the genomes of Native Americans. And the two groups disagree about how it got there.”
