Mouse migration - Viking style

An article in a Royal Society journal suggests that modern British mice may have "Viking" genetics - or at least may have traveled with the Scandinavian invaders on their journeys of conquest.

The DNA of the British mice is similar to that of their Nordic cousins, says Professor Jeremy Searle from York University, leading researchers to believe that the mice accompanied the Vikings on their travels. "If we look at the genetic patterning of the mice, we find they have patterning that very much relates to human history; and so we get a particular genetic type of mouse that is found in the region where the Norwegian Vikings operated," Searle told BBC News.
