A new DNA study done on ancient Alaskan babies shows how Native Americans progressed through the ages. The remains of two babies which were apparently buried in Alaska about 11,000 years ago show very good evidence that the first Americans probably spent thousands of years living there before they decided to move into the areas of North and South America.
This new discovery might indicate that Native American which originally migrated from Asia settled and lived on the Bering land bridge for a very long time before they decided to move further down South.
The remains of the babies were found in the Upward Sun River and they apparently had different mothers. One of them was just a 6 to 12 week old baby while the other seems to be a preterm fetus which could have possibly been stillborn.
These new DNA studies show that a long standing hypothesis called the “Beringian standstill” might actually be true. The theory suggest that the ancestors of Native Americans living in America nowadays might have spent a long period of time being isolated from other populations. It shows that their DNA became more and more differentiated from their Asian roots.
All of the Native American lineages don’t show any traces of DNA related to the Asian area of the world. This definitely means that they spent a long time in isolation away from other civilizations. This would explain how they managed to evolve away from their Asian ancestors.
This is a clear case in which DNA has helped archaeology enthusiasts greatly. Further finds like this one could explain a lot about how cultural lineages have evolved and changed over long periods of time.
The groups of people that lived in the area of the Upward Sun River might are probably a part of the huge number of people that rapidly moved to the south of the Americas about 15,000 years ago. This is the conclusion that seems most likely to the researchers who created this study.
Scientists are very excited over this finding mostly because what was once Beringia is nowadays not accessible because it is underwater. This might be the closest we will ever get to actually being able to see what genetic makeup the Beringians had.
