In the sub-arctic environment in northern Norway and the high arctic climate of Svalbard, reindeer have adapted to their environment in different ways. The five video tracks in this album explore the key concepts of evolutionary science and investigate how these account for the characteristics of arctic reindeer. How do natural selection and other evolutionary processes produce changes in genes? How do new species originate? And how are large-scale evolutionary patterns generated. The material forms part of the course S366 Evolution.
