Zoologist Arik Kirschenbaum, author of *Why Animals Talk*, dives into the captivating world of animal communication. He discusses why animals can't speak human language and explores the unique ways different species convey messages. Discover how parrots mimic human speech while other birds don’t, and learn about the communicative talents of dolphins and wolves. Arik also shares insights into the evolutionary roots of language and the complexities behind animal interactions, sparking curiosity about the communication of our furry and feathered friends.
Animal communication varies widely from humans, using methods like vocalizations and body language tailored to their environments.
The evolution of human language complexity emerged from social needs, larger brains, and the transition to living in bigger groups.

The Nature of Animal Communication
All animals communicate, but their methods vary significantly from the human use of language. Communication can include vocalizations, body language, smell, and other forms. For example, simpler animals often rely on smell to convey messages to one another, which goes unnoticed by humans. This distinction highlights that while all animals can communicate, the complexity and formality of communication varies greatly, especially when compared to human language.
The Evolution of Human Language
The ability of humans to speak and use complex language may have evolved due to the need for communication in larger social groups. As humans transitioned from jungle to savannah living, larger groups necessitated more intricate communication systems to share vital information and coordinate activities, such as hunting. Furthermore, the evolution of larger brains likely facilitated this transition, enabling the development of language alongside social complexity. This suggests that while communication is universal among animals, the unique demands of human existence required a more advanced form of interaction.
The Role of Sound in Communication
Sound serves a critical role in communication among animals due to its ability to travel quickly and penetrate obstacles. Unlike visual signals that can be blocked by objects, sounds can be heard from a distance, making them effective for alerting others to danger or signaling location. Different animals adapt their communication methods based on their environments; for instance, in noisy rivers, animals may rely on visual or physical cues rather than sounds. This adaptability emphasizes the importance of sound as a versatile communication tool across various species.
Interspecies and Individual Communication
Although most animals primarily communicate with others of their own species, there are instances of interspecies interactions and individual-named recognition, particularly in intelligent species like dolphins and elephants. Some animals, such as parrots, can mimic human speech, though this ability does not indicate true language understanding. Additionally, particular animals exhibit unique communication behaviors, such as wolves howling for territory or to reunite with pack members, highlighting the social structures and needs behind their vocalizations. This fascinating interplay reveals that while animals may not speak our language, they have distinct methods of conveying meaning and emotions.
Why can’t animals talk to us? Are humans the only animals that can talk? Can different species of animals communicate with each other? We learn about animal communication with Arik Kershenbaum, author of Why Animals Talk: The New Science of Animal Communication. He studies wolves, gibbons, dolphins and hyrax to learn how they communicate. Also in this episode: why are parrots able to speak human words but other birds can’t?
