From the
National Geographic:
Five hundred
years before Columbus sailed the ocean blue, a Native American woman may
have voyaged to Europe with Vikings, according to a provocative new DNA
study.
Analyzing
a type of DNA passed only from mother to child, scientists found more
than 80 living Icelanders with a genetic variation similar to one found
mostly in Native Americans. (Get the basics on genetics.)
This
signature probably entered Icelandic bloodlines around A.D. 1000, when
the first Viking-American Indian child was born, the study authors
theorize. (Related: "Vikings' Barbaric Bad Rap Beginning to Fade.")
Historical accounts
and archaeological evidence show that Icelandic Vikings reached Greenland just before 1000 and quickly pushed on to what is now
Canada. Icelanders even established a village in
Newfoundland, though it lasted only a decade or so (
regional map).
The idea that a Native American woman sailed from North America to Iceland
during that period of settlement and exploration provides the best
explanation for the Icelanders' variant, the research team says.
"We
know that Vikings sailed to the Americas," said Agnar Helgason of
deCODE Genetics and the University of Iceland, who co-wrote the study
with his student Sigrídur Ebenesersdóttir and colleagues. "So all you
have to do is assume … that they met some people and ended up taking at
least one female back with them. (Read entire post.)
