Possible pre-Columbian Native American gene found in modern Icelanders

An Icelandic company called deCODE genetics (previously) has found evidence, though not conclusive, that an unknown American woman traveled to Iceland, possibly against her will, as early the year 1000 but not later than 1700. She had offspring in Iceland with natives. 80 of her descendants are still extant in that country. This finding has been announced in a pre-print online publication of the American Journal of Physical Anthropology. The work involved explorations of mitochondrial DNA, which are frequently employed to examine humans' centuries-old lineages. One surprising result is that this lineage does not seem to line up with previously known Native American genetic markers, but the authors believe that the explanation above is "[more] likely" than this common ancestor being European or Asian.
