Viking mice rejected Newfoundland

It appears that Viking mice, which traveled on ships with their human warrior companions, found Newfoundland mostly not to their liking, according to a new study evolutionary biologist Eleanor Jones in the journal BMC Evolutionary Biology.

In the Middle Ages, the Norse colonized Iceland and Greenland, leaving behind mice from their ships, but they abandoned settlements in Newfoundland. Even the mice seemed to find the climate too harsh. Jones' research team "found no genetic connection between modern Newfoundland mice and those found in Iceland and Greenland, which shared DNA markers from mice remains linked with Norwegian Vikings."
