U of U DNA study links Native Americans to Bering land bridge

SALT LAKE CITY – Scientists from the University of Utah found that the genetic material from two babies from different mothers buried together in Alaska supports the idea that Native Americans descend from Siberians.

The babies were buried together in an 11,500-year-old Alaskan campsite, they are the northernmost ancestors to multiple groups of Native Americans.

“These infants are the earliest human remains in northern North America, and they carry distinctly Native American lineages,”  said University of Utah anthropology professor Dennis O’Rourke.

Researchers say that finding both of those genetic chains so far north supports the idea that groups migrated from Asia onto the Bering land bridge between Siberia and Alaska, and stayed there for up to 10,000 years.

“We see diversity that is not present in modern Native American populations of the north and we see it at a fairly early date,” said O’Rourke. “This is evidence there was substantial genetic variation in the Beringian population before any of them moved south.”

The genetic material from each set of remains separately connects to dozens of tribes all over North America.

This theory is called the “Beringian standstill model”.

Scientists point to this ancient DNA as essential information in researching how the Western Hemisphere was populated.

    O.K. Science has already found that mt-DNA haplogroups A, C & D came across the Bering Strait, there are ties to Mongolia and Siberia. Haplogroup B is believed to be Pacific Island hoppers, but could also have come across the strait.

    How about Haplogroup X? Mostly found around the Great Lakes, but might also be found around Mound Builder sites.

    My DNA test shows two native tribes, one with Asian and the other doesn’t have it. Rumor and locality leads to Lumbee and Powhatan. My family was also near Cherokee, but no stories as of yet.
