Modern Arctic Tribes Linked Back To Ancient Alaskan Village Through DNA Study

In grade school you may have been taught about the migration theory that supposes that humans migrated to the Americas by means of the pre-historic land bridge in the Bering Straight. That theory would have you believe that all humans who inhabited these two continents prior to the European conquests would have been derived from a common ancestor. Well, not all of that theory holds true, but for some cultures there are some solid links to the Western Alaskan coasts thanks to a study conducted of mitochondrial DNA. By comparing the DNA composition of modern day indigenous tribes across Alaska, Canada, and even Greenland scientists have been able to determine that many of them share a common set of ancestors.

The tribes of pre-historic Inuit and other similar natives may have faced the bitter cold of the glacial regions of North America, but they managed to migrate all across the continent’s Northern coasts. These blood lines traveled as far away as Greenland, many thousands of miles away. It is not clear if this migration was made solely on foot, or if these ancient tribes possessed the ability to travel by water back then.

The mitochondrial DNA links many of these Northern tribes to a common ancestral lineage that is centralized along the Northern shores of Alaska. Human remains that had been somewhat preserved for many thousands of years provided enough DNA samples for laboratories to construct the basic DNA sequence of those people. The age of these remains is estimated to be many thousands of years old, to rule out the possibility that they may have been from more recently deceased specimens.

Links between mitochondrial DNA imply that women from these ancient tribes traveled far across the continent. Mitochondrial DNA is the feminine building block of the human genome sequence, and is passed down from mother to child. With some further analysis of the male chromosome and its DNA sequences, the research may be able to later conclude more findings about the overall inter-breeding and family relationships within the pre-historic and modern native tribes of the American continents.
