Do animals speak and if so why do they do so? What do they say? From the evolutionary standpoint what exactly is happening there? Dr Arik Kershenbaum is a zoologist who teaches at the University of Cambridge. His most recent book, “Why Animals Talk: The New Science of Animal Communication” addresses these questions. In this podcast Dr Arik talks about his experience of studying animal sounds in their live habitats to tell us why and what they are trying to say.
