Underneath the waves of Scotland's seas there is a hive of communication going on. Clicks, shrieks, calls and whistles that can be heard for over 15kms. They are highly developed forms of communication, some evidence even shows local dialects among our two main native populations of Bottlenose dolphin in Scotland. What started as a career trying to work out the similarities between how animals and humans perceive the world around them led Professor Vincent Janik, Director of Scottish Oceans institute at St. Andrews University, to focussing his work on the nuances of how dolphins address each other, how they communicate. In this episode of Brainwaves Pennie Latin explores what makes dolphin communication some of the most advanced of the animal kingdom and what we can learn about the development of language and brain function in humans by comparing ourselves to the dolphins.
