View Full Version : Indian DNA links to 6 'founding mothers'

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.

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.

Fascinating. It was interesting that they found that they couldn't trace the mothers to Asia though. Instead they trace it to a now lost bridge between Asia and America. It kinda points to a rapid migration from Asia to America wherein there wasn't enough time for mitrchondial DNA to leave a footprint.

Sorry brother. That went right over my head. I'm not sure what point you are making -- I'm a bit dense tonight :lol:

The paper is about a small sub-set of of the human population that we call "Native Americans"

Here is the original manuscript if you are interested:

Think he is refering to:

So since the DNA does not show itself to have ever been from Asia........... I don't know you know about this stuff better then I do. :hi5:

The sample size was very small. The group relies on volunteers to donate cheek swabs for DNA comparison. If no one of a direct line (on both sides -- Asian and American Indian) happens to find their site and happens to click the 'request a kit (http://www.smgf.org/pages/request_kit.jspx)' link, there is not going to be a match.

This finding was published in a third tier 'journal' by an institute that is a proxy of BYU (the LDS church). My guess is that if the authors had submitted this paper based on a such a small sample to Nature (http://www.nature.com/nature/index.html) or Science (http://www.sciencemag.org/), the manuscript would have been hammered by the reviewers.

After reading the link you can clearly see that they state that this is a very , very small subset, and their conclusions are suggestions at best. But it is a fascinating field of study. What I got out of this study, and others, is a relatively fast migration from asia.
