Historians have long believed that the first humans to populate the Azores, a group of islands about 870 miles off the coast of Portugal, arrived in the fifteenth century.

Portuguese mariners may not have been the first humans to populate the Azores.

In their 2015 study, the researchers found a genetic connection between house mice in the Azores and those in Scandinavia.

According to a 2015 study, the first humans to populate the Azores may have been Vikings from Scandinavia, not mariners from Portugal as previously believed.
