This result does not mean that only six women in the original population of the North American continent have immigrated from Asia to North America.
This result does not mean that only six women led to the initial influx of immigrants from the Asian continent into the United States.
On the contrary, it shows that only six people left a specific DNA legacy, which continues to this day among about 95% Native Americans, said Ugo Perego, a Utah study co-author.

He said that these women don't necessarily arrive together, or even live at the same time. The results show that these women arrived sometime between 18000 and 2 1000 years ago.

Perego said that this work confirmed the evidence that there were only six maternal lineages before, and the date when the first people crossed the continental bridge from Asia to North America about 20,000 years ago.
Perego said that this work confirmed previous indications that there were only six maternal lineages, and when the first man arrived in the United States about 20,000 years ago, a land bridge was formed from Asia.
The researchers studied mitochondrial DNA, which is only passed from mother to daughter. They created a "family tree" to trace the different DNA lineages found among today's Native Americans. By recording the mutation in each branch and applying a formula to calculate the frequency of this mutation, they calculated the age of each branch. This shows that when each branch is now a woman.
The researchers studied the mitochondrial gene, which was transmitted only through the mother's daughter. They created traces of "genealogy" with different gene lineages, which are found among Indians today. The catastrophe formula is used to pay attention to each branch and the time when the catastrophe occurs, and how the old branch is calculated. This means that when a woman appears in every branch.
Perego said that the six "founding mothers" obviously did not live in Asia because their DNA signatures were not found there. He said, so they may live in Belinga, the now submerged land bridge to North America.
Perego said that the six "founding mothers" obviously didn't have the signatures of living in Asia, because what they left behind was not found. So they may live on the bridge in the Bering Strait of North America, which is now flooded, he said.
