Three new studies “shake up” study of human migrants to North America

We used to think the picture was pretty simple but not any more:

By sequencing and analyzing 15 ancient genomes found throughout the Americas—six of which were older than 10,000 years—these researchers determined that, around 8,000 years ago, the ancestors of Native Americans were still on the move, migrating away from Mesoamerica (what is today Mexico and Central America) toward both North and South America. These groups moved rapidly and unevenly, sometimes interbreeding with local populations, complicating the genetic—and historical—picture even further.

Apparently, they traveled “great distances at breathtaking speed.”

Potter said genetic data is wonderful, but it doesn’t tell us the whole story. Unlike genetics, archaeology can secure timelines and geographic locations, while also showing continuity and changes to technology, adaptive strategies, and material and cultural connections across time and space. Potter said the new studies will allow “much more complex and realistic models to be developed,” but this process will “require collaboration with archaeologists and geneticists.” George Dvorsky, “Three New DNA Studies Are Shaking Up the History of Humans in the Americas” at Gizmodo
