The Azores, an autonomous region of Portugal in the middle of the Atlantic, was said to be discovered in 1427 by Portuguese explorer Diogo de Silves. However, new studies of the land suggest the Portuguese may not have been the island's first inhabitants. The key to these studies? Mice. Similarities have been found between Azorean and northern European mice. In this episode, Cat is joined by Ecology and Evolutionary Biologist Dr. Jeremy Searle from Cornell University. We delve into this unexpected location of Viking occupancy, exploring Jeremy's research on the land and the mice who can tell us more about our complex history. What can mice tell us about the movement of people in the past? Our GDPR privacy policy was updated on August 8, 2022. Visit acast.com/privacy for more information.
