Native Americans, Aboriginal Siberians Believed Had Shared Common Language: Study

In a new study it is believed the early Native Americans that settled on beringia moved back home.

PLOS ONE journal’s press release writes the Americans settled in the middle of a bridge that connected Alaska to Asia. They stayed there for around 10,000 years and thereafter disappeared into the ocean.

Currently the land bridge is called as Bering Strait.

The press release adds further that information was collected based on the sound systems and word structure from published grammars of several languages that were spoken by the Native Americans. It was called as Na-Dene. Information on Yeniseian languages spoken in Central Siberia was also collected by Gary Holton from University of Alaska Fairbanks and Mark Sicoli from Georgetown University in Washington, D.C.

By using a computational phylogeneticsm technique Holton and Sicoli studied linguistic dataset by making a language family tree to represent relationships of common ancestry.

The technique was developed to find out the evolutionary relationships between biological species.

In a press release Sicoli said they tried computational phylogenetic methods to make family tree relationships modeling in Out-of-Beringia hypothesis and also on Out-of-Asia hypothesis, and found evidence for out-of-Beringia dispersal.

The new study however does not dispute the migrational theory of land bridge, but it says not everyone was able to complete the journey.

In addition to all these, the new finding also shows how the mysteries of migration and evolution can be solved by using the latest linguistics technology.

This polar projection map of Asia and North America shows the approximate terminal Pleistocene shoreline. The center of geographic distribution of Yeniseian and Na-Dene language is in Beringia. From this center burgundy arrows extend toward the North American coast and into Siberia. A blue arrow indicates Interior dispersals of Na-Dene.
