The recent genetic analysis of DNA from 11,500 years old infant has been discovered at the Upward Sun River, which is an ancient campsite located in Interior Alaska. The researchers have entitled the new group as ‘Ancient Beringians’, whose research theories were disclosed in the in the journal Nature on 3rd January, 2018.
Anthropology professor and a leading author of the theory, Ben Potter from the University of Alaska Fairbanks, said in a statement that, “We didn’t know this population existed. These data also provide the first direct evidence of the initial founding Native American population, which sheds new light on how these early populations were migrating and settling throughout North America.”
The DNA discovery shows that a single establishing group of Native American from the most ancient population was forked from East Asians nearly 35,000 years ago. The group then was split again in to two classes around 20,000 years ago, which is then known as ancestors of the entire population of Native Americans, i.e. Ancient Beringians.
According to the research team, the DNA evidences also indicated two new scenarios for theory of how humans peopled the New World. “One is that there were two distinct groups of people who crossed over the Beringian land bridge prior to 15,700 years ago. A second is that one group of people crossed over the land bridge and then split in Beringia into two groups: Ancient Beringians and other Native Americans, with the latter moving south of the ice sheets 15,700 years ago”, say researchers.
