The mysterious extinction of the dire wolf

DNA clues point to how dire wolves went extinct, and a round-up of the main impacts of Brexit on science.In this episode:00:45 Dire wolf DNADire wolves were huge predators that commonly roamed across North America before disappearing around 13,000 years ago. Despite the existence of a large number of dire wolf fossils, questions remain about why this species went extinct and how they relate to other wolf species.
