Native Americans actually came from a tiny mountain region in Siberia, DNA research reveals

* tiny region in central Russia has DNA binding Native Americans today
* ancestors are believed to have walked across the ice 13,000 years ago
* Altai is "key place" due to its central location, ancient peoples went through

Altai in southern Siberia is located right in the center of Russia. But the small mountainous republic has a claim the unknown fame so far - native Americans can trace their origins to the remote region

DNA research revealed that genetic markers linking people living in the Russian republic of Altai, in the south. Siberia, with indigenous people of North America.


A study of mutations indicates a change of lineage between 13,000 ago and 14,000 years -. when you think that people who have walked across the ice from Russia to America

This roughly coincides with the period in which it is believed that humans from Siberia to have crossed what is now is the Bering Strait and entered the United States.


"Altai is a key area because it is a place where people have been coming and going for thousands and thousands of years, "said Dr. Theodore Schurr of the University of Pennsylvania in the US ..

Among people who may have arisen of the Altai region are the predecessors of the first native Americans.

about 20-25,000 years ago, these prehistoric humans carried their Asian genetic lineages to the ends of Siberia and finally through the mass Bering land after exposed-in the Americas.

"Our goal in working in this area was to better define what the founders or lineages sister lineages are indigenous people of America," Schurr said.

the region lies at the intersection of what is now Russia, Mongolia, China and Kazakhstan.


the Dr. Schurr team checked Altai DNA samples for markers in mitochondrial DNA is always transmitted by mothers, and Y chromosome DNA that children inherit from their parents.

Due to the large number of gene markers examined, the results have a high degree of accuracy.

"At this level of resolution we can see the connections more clearly," Schurr said.

Looking at the Y chromosome DNA , the researchers found a unique mutation shared by native Americans and southern Altaians in the lineage known as P.

mitochondrial DNA is rod-shaped small power plants' in cells that generate energy.

Both types of DNA showed links between Altaians and native Americans.


the DNA of the Y chromosome, the researchers found a unique mutation shared by native Americans and people of southern Altai.

the results are published today in the American journal of Human Genetics.

the calculation of how long the mutations they observed led to emerge, the team Schurr estimated Altaian lineage south genetically separated native American lineage 13,000 ago to 14,000 years, a timing scenario that aligns with the idea of ​​people moving in the Americas from Siberia between 15,000 and 20,000 years ago.

Although it is possible, even likely, that more than one wave of people crossed the land bridge, Schurr said other researchers have not been able to identify a geographical focal point like from which native Americans have ancestors.

"can be changed with more data than other groups, but so far, even with intensive work in Mongolia, they are not seeing the same things we are," he said .

in addition to clarifying connecting Asia and America, the study confirms that modern cultural divide between Altaians south and north has ancient genetic roots
