Arik Kershenbaum, a zoologist and lecturer at the University of Cambridge, explores the fascinating world of animal communication. He reveals how dolphins use signature whistles much like names and discusses wolves' unique vocal accents. Kershenbaum also delves into the complex social interactions and learning methods of animals, emphasizing their rich emotional lives. The conversation sheds light on how understanding these communications can enhance our grasp of both animal identities and the evolution of human language.
Hyraxes exhibit structured vocal communication resembling human syntax, indicating social learning and cognitive complexity among animals.
Social structures influence animal communication styles, with more complex vocalizations found in highly social species like dolphins and wolves.

Hyraxes and Their Unique Communication
Hyraxes, small mammals resembling a mix of rabbits and guinea pigs, are fascinating not only for their appearance but also for their vocal communication. They utilize a form of syntax in their vocalizations, indicating a structured way of combining sounds, similar to how humans arrange words in sentences. This suggests that hyraxes have learned communication methods from their peers, emphasizing the social learning aspect of animal communication. Their vocal behavior raises intriguing questions about the potential existence of language among animals, hinting at a deeper cognitive complexity than previously recognized.
Social Complexity Drives Communication
The social structures of animals significantly influence their communication styles, with highly social species exhibiting more complex vocalizations compared to solitary ones. For example, animals like birds use songs to establish territory and mate, while those that live in groups often develop intricate ways of expressing needs and emotions. This relationship between social behavior and communication needs underlines the evolutionary purpose of vocalization, which is to efficiently exchange information within a group. Understanding how different species communicate can provide insights into their social dynamics and behavioral interactions.
Sound as a Medium for Communication
Sound plays a crucial role in animal communication due to its ability to travel long distances and penetrate obstacles, making it an effective medium for conveying messages. Wolves, for instance, use howling for long-range communication while employing shorter sounds like whining and growling for interactions within the pack. This duality allows wolves to maintain social bonds and coordinate activities over vast territories. The technical distinction between tonal sounds and noisy sounds further emphasizes the adaptability of vocal communication in varying contexts to suit the animals' needs.
Learning and Individuality in Animal Sounds
Research suggests that animals develop their vocalizations over time, often influenced by their social environment, which leads to variations similar to dialects in human language. Dolphins, for instance, utilize signature whistles that act like names, and their social interactions are shaped by complex relationships. This capacity for individual sound production not only enhances social cohesion but also reflects the cognitive demands of navigating social structures. The ability to recognize and differentiate sounds among individuals indicates a sophisticated level of communication that is more widespread in the animal kingdom than previously thought.
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.”
