Alaskan baby bones reveal Native American migration from Asia to America via a landmass known as the Bering Strait. DNA material taken from the graves of two ancient Alaskan baby skeletons provides new insight into how humans first migrated to American soil.
The baby skeletons date back 11.500 years and have Native American lineages. Researchers have also found that they had different mothers and were connected to North and South American Indians. The place in which they were have been found as well as the evidence of their descent support the theory that Native Americans are descendants of a mongoloid race that originated in Asia and then migrated to America.
The remains are a token of the earliest settlers in America and the distinct features of Native Americans may also support the additional theory that the original migrants didn’t just cross the Bering Strait from Asia to America but that they also settled there for a long period of time, enough to facilitate the development of the unique Native American characteristics.
Such skeletal remains from that time period also show genetic diversity no longer found in modern Native American populations in the north and appear to date from early settlement in the region.
The changes that affected the ancient populations that lived on the Bering Strait are reflected in the genetic specificities that have been discovered. Their migration south has also left a mark on their genetic codes, applying slow mutations to it.
Today we can no longer find genetic similarities between Asian and Native American populations which also points to a change in their genes, one that happened sometime during their migration to their new homes in the Americas.
Also supporting this theory is the fact that, in the oldest graves that have been discovered in this area, there has been found evidence that can trace DNA samples that are buried there to all of the five Native American lineages that exist today.
The discovery of the two infants, who had Native American DNA pertaining to specific groups, further supports the hypothesis that an Asian population migrated through the Bering Strait. The fact that their DNA was Native American and not Asian also shows that their mothers had lived separately from Asian populations for some time, and had developed specific Native American traits.
What makes the discovery all the more unusual is the fact that the children even received a burial and are located in the same place, despite having different mothers. One of the assumptions made by researchers is that they may have had the same father, but there is no conclusive proof of that yet.
