Ancient Humans May Have Gone to North America Then Turned Around

Ancient Native American populations may have "back migrated" into northeastern Asia, findings from a study published in the journal Current Biology indicate.
The paper sheds light on the history of human migration between Asia and North America and how ancient peoples in the region mixed.
There is a consensus among scientists that the Americas were first settled by people who traveled from Asia, although a number of questions remain about how exactly this process occurred.

"I would say we—archaeologists and geneticists—are in relative agreement about major elements of the peopling of the Americas, but differ drastically on some of the details," Ben Potter, a professor in the Department of Anthropology at the University of Alaska Fairbanks, who was not involved in the Current Biology paper said.
