Dolphins call each other by name, wolves have accents — researchers are discovering all sorts of fascinating facts about animal communication. Arik Kershenbaum is a zoologist, college lecturer and fellow at Girton College, University of Cambridge. He joins host Krys Boyd to discuss what we’re learning about how animals talk to one another, how that understanding also sheds light on human language, and how we might come to better understand animal identities and emotions. His book is “Why Animals Talk: The New Science of Animal Communication.”
