Native American populations share gene signature

A distinctive, repeating sequence of DNA found in people living at the eastern edge of Russia is also widespread among Native Americans, according to a new study.
The finding lends support to the idea that Native Americans descended from a common founding population that lived near the Bering land bridge for some time.
Kari Schroeder at the University of California in Davis, US, and colleagues sampled the genes from various populations around the globe, including two at the eastern edge of Siberia, 53 elsewhere in Asia and 18 Native American populations. The study examined samples from roughly 1500 people in total, including 445 Native Americans.
The team looked for a series of nine repeating chunks of DNA, known as 9RA, which falls in a non-coding region of chromosome 9.
They found the 9RA sequence in at least one member of all the Native American populations tested, such as the Cherokee and Apache people. The two populations in eastern Siberia, where the Bering land bridge once connected Asia to North America, also tested positive for the 9RA sequence.
The 9RA sequence did not appear in any of the other Asian populations examined in the study, including those from other parts of Siberia, from Mongolia or Japan.
According to Schroeder, the high prevalence of this gene marker among native populations of North and South America - and its absence in most of Asia - lends strong support to the idea that Native Americans can trace their ancestry to a common founding population.

"...oh the thought of ancestors brings a tear to my eye....Im a what?????...a Sicilian?????"
....put edible plants in the ground?.
..fight off bear and other malicious animals?.
....build protection from the weather?.
....burn wood for fuel?.
sounds like Puritans and Pilgrims to me...
The holder of this title is believed by some to have lived about 140,000 years ago in what is now Ethiopia, Kenya or Tanzania. The time she lived is calculated based on the molecular clock technique of correlating elapsed time with observed genetic drift.
Mitochondrial Eve is the most recent common ancestor of all human via the mitochondrial DNA pathway, not the unqualified MRCA of all humanity. All living humans can trace their ancestry back to the MRCA via at least one of their parents, but Mitochondrial Eve can only be reached via the maternal line. Therefore, she necessarily lived much longer ago than the MRCA of all humanity.
If she is everyone's great great Grandmother, many centuries removed, then we're all cousins and AFRICAN-Whatevers!!!
This could explain the failure of Indian Tribal governments as well.

The 9RA mutation probably occurred in an ancestral population located at the eastern edge of Siberia, which subsequently migrated over the Bering land bridge, Schroeder says (watch how the land bridge was gradually submerged as see levels rose).
But what about the red-haired, blue-eyed Indians who spoke Welsh?

I'm not confident that our native American populations are any longer distinct from one another, at least not in the west. Due to the requirement that reservations maintain a certain size population to remain an official reservation, our local reservation takes in anyone with any type of Indian family history, including Mexican Indians.
OK, blam, you caught me lost in the Journey of Mankind for maybe the 4th time...LOL! It's such a good site.
Plus, there has been a large amount of admixture with European and African descent populations.
The average percentage of native blood on the reservation is very small indeed. I suspect that is the reason for accepting Mexican Indians. I think that the percentage of native blood may be higher.
American Indians are a product of multiple migration. The latest migrations is what is the gene.
Yup, he was a Fake Indian.
Doesn't really sound all that rousing of an endorsement.
Even less so, when one looks at all the major milling around & changing of "ancestral territories" that has gone on among the tribes just since Europeans arrived.
Could that be a result of westward migration? or of bidirectional migration? Is the storied "land bridge" strictly one-way?
It get me all the time. Go here and click on 'Genetic Markers' (at the bottom) and see if you can help me locate the 9RA mentioned in this article.
martin, My brother and I want to have our DNA checked. How should we go about it? I don't know the first step.
He was actually from the Watsituya or Fugawe tribe. I'm not absolutely certain.
You are an evil person! Do you know how long I've been lost in that site! LOL! I'm still looking...
You're doing better than I am; I just know he wasn't Hekawi.
My sister and I both ordered our DNA test kits from here today for $107.50 each. She is asking for a mtDNA (female) and I'm asking for the Y chromosome (male) test.
Also, you may want to read this article too.

LOL. I lose hours on these things.
This book will help you decipher your origins once you get your DNA done.
He may have pow wowed with the Sosumis..
Thanks again, I'll get it. I have pure Brit ancestry as far as I can tell. My husband has half Brit half French ancestry.
"If she is everyone's great great Grandmother, many centuries removed, then we're all cousins and AFRICAN-Whatevers!!!"
But where does the infusion of alien DNA fit in? I mean, perhaps we are all Vulcan-whatevers.
Perhaps you need to watch "2001 a Space Odyssey". Pay attention to the end where the Star Child is hovering over the Earth and smiling.
No no no . . . that's the NEXT phase of evolution.
The Obelisk was planted during the early stage of the humanoid's development. Whose to say there wasn't some "monkey businees" goin' on!
That's my theory and I'm sticking to it.
