Indian DNA Links To 6 'Founding Mothers'

Indian DNA links to 6 'founding mothers'

By MALCOLM RITTER, AP Science Writer

NEW YORK - Nearly all of today's Native Americans in North, Central and South America can trace part of their ancestry to six women whose descendants immigrated around 20,000 years ago, a DNA study suggests.

Those women left a particular DNA legacy that persists to today in about 95 percent of Native Americans, researchers said.

The finding does not mean that only these six women gave rise to the migrants who crossed into North America from Asia in the initial populating of the continent, said study co-author Ugo Perego.

The women lived between 18,000 and 21,000 years ago, though not necessarily at exactly the same time, he said.

The work was published this week by the journal PLoS One. Perego is from the Sorenson Molecular Genealogy Foundation in Salt Lake City and the University of Pavia in Italy.

The work confirms previous indications of the six maternal lineages, he said. But an expert unconnected with the study said the findings left some questions unanswered.

Perego and his colleagues traced the history of a particular kind of DNA that represents just a tiny fraction of the human genetic material, and reflects only a piece of a person's ancestry.

This DNA is found in the mitochondria, the power plants of cells. Unlike the DNA found in the nucleus, mitochondrial DNA is passed along only by the mother. So it follows a lineage that connects a person to his or her mother, then the mother's mother, and so on.

The researchers created a "family tree" that traces the different mitochondrial DNA lineages found in today's Native Americans. By noting mutations in each branch and applying a formula for how often such mutations arise, they calculated how old each branch was. That indicated when each branch arose in a single woman.

The six "founding mothers" apparently did not live in Asia because the DNA signatures they left behind aren't found there, Perego said. They probably lived in Beringia, the now-submerged land bridge that stetched to North America, he said.

Connie Mulligan of the University of Florida, an anthropolgist who studies the colonization of the Americas but didn't participate in the new work, said it's not surprising to trace the mitochondrial DNA to six women. "It's an OK number to start with right now," but further work may change it slightly, she said.

That finding doesn't answer the bigger questions of where those women lived, or of how many people left Beringia to colonize the Americas, she said Thursday.

The estimate for when the women lived is open to question because it's not clear whether the researchers properly accounted for differing mutation rates in mitochondrial DNA, she said. Further work could change the estimate, "possibly dramatically," she said.

Has any one ever done sea bed studies to see if that area actually connected despite the common sense view that it probably was....seems to me they could do some core studies to see if they could find human artifacts from about that era before the seas submerged that area.

This is interesting because my Wife insist Native Americans did NOT come from Asia and may well have been here all along.

A show on the History channel (Making of 10,000 BC) suggested 2 or more groups came here 13,500 years ago. One from Europe and another from Asia.

It’s just a easy for me to believe some groups may have come from the south.

I think you are right. I believe some Polynesians made it to South American and came north, making three ports of entry.

If there where only six original women then I'm going to take a guess a say that the Indians arrived by boat rather then a supposed land mass.

More would have arrived if they came by a land bridge, IMHO.

The land bridge still seems to have been the source for most migration. There were one or more coastal migrations, but they seem to have been small, and didn't result in much spread to the interior.

Here is a good recent article: Beringian Standstill and Spread of Native American Founders.

Even so...

Vintage Skulls

"The oldest human remains found in the Americas were recently "discovered" in the storeroom of Mexico's National Museum of Anthropology. Found in central Mexico in 1959, the five skulls were radiocarbon dated by a team of researchers from the United Kingdom and Mexico and found to be 13,000 years old. They pre-date the Clovis culture by a couple thousand years, adding to the growing evidence against the Clovis-first model for the first peopling of the Americas."

"Of additional significance is the shape of the skulls, which are described as long and narrow, very unlike those of modern Native Americans."

Yams (sweet potatos) are native to south america. There had to be colonization at some point in order for Polynesians to have picked up sweet potatos. It isn’t quite like fruit where you plant it, watch the tree pop up, and remember the fruit. You’d need to get cuttings/roots to plant to propogate it, which would take more than a food raid on the coast to get.

It would be prohibitively expensive to take cores, and the chance of getting human artifacts from that era would be miniscule.

Great.....now I'm supposed to call them Native Beringians?

First, American Indian was replaced with Native American. African American is fashionable, despite the fact the CP in NAACP stands for Colored People. Congress still has the Black Caucus and there's still the United Negro College Fund.

How am I supposed to keep all my PC lingo straight?

There are only 6 surviving lineages of mitochondrial DNA. The original group (if 5000 people were involved) probably had about 2000 females.

Or, you could have had 20,000 females, some bad luck, and only 6 lineages surviving.

Obviously all the blue-eyed blonds died out eh~!

There’s a later migration about 5,000 BC. We know them from their languages.

The original Japanese, the Ainu people.

Not those Korean invaders we know as modern Japanese. There are still groups of them living on the Northern Islands. Ian Fleming noted their "more Caucasian" appearance and so hid Bond amongst them in "". The movie version, as usual, screwed it up and had the babe he was living with be a modern Japanese.

Study Says Americas Settled 15,000 Years Ago

"The early immigrants most closely resembled the prehistoric Jomon people of Japan and their closest modern descendants, the Ainu, from the Japanese island of Hokkaido, the study said. Both the Jomon and Ainu have skull and facial characteristics more genetically similar to those of Europeans than to mainland Asians.

Geneticist Bryan Sykes talks about this in one of his books - I think it's the one on the Y Chromosome. Polynesian men travelled to the S. American coast, picked up some crops (like yams) and left Y chromosomes among the Indians there. They're pretty sure it was male-only groups, because they haven't found any Polynesian mitochondrial DNA in S. America (i.e. the kind passed on by women.)

The Arctic languages are in two groups, and within those groups aren’t very differentiated, as if each is from a single, recent small-group arrival. Farther south in North America, and particularly in South America, the languages are a riot of unrelated and overlapping groups. This means (as one would expect, and which is taken as a given everywhere else in the world such conditions are found) that they’ve been there a long time and the linguistic ancestors didn’t arrive together.

“There were only six original women,”

Actually, there may have been a lot more. The mitochondria are only passed from mother to daughter. My grandmothers had 5 daughters and one son on one side, and 2 sons on the other. The 5 daughters had 8 sons and one daughter. The one granddaughter had two sons. End of the line for that mitochondrial DNA. So over the millenia, a lot of women never passed on their mitochondrial DNA.

Good point. It could have been six tribes or “nations” if each tribe or nation had a single maternal ancestor (which at some point seems likely). It doesn’t mean only six women showed up.
