NEW YORK (AP) - A new study of DNA suggests nearly all NativeAmericans can trace part of their ancestry to just six women whose
descendants immigrated to the Americas some 20,000 years ago.
Researchers say the women left a DNA legacy that can be found in
about 95 percent of native people throughout the Americas.
But one of the study's authors notes that the finding does not
mean that those six women were the only ancestors of the migrants
who populated the Americas from Asia. He says the women lived some
time between 18,000 and 21,000 years ago, but may not have lived at
the same time. And he says they do not appear to have lived in
Asia, but rather on a now-submerged land bridge that once connected
the continents.
The work confirms previous indications of six "founding
mothers." It's published this week by the journal PLoS One.
