He chose the title to emphasize the 'why' behind animal communication, focusing on the evolutionary drivers rather than just the 'how'. He believes understanding the reasons for communication is more insightful than merely describing how it works.
The central theme is that animal communication is driven by social interactions. The complexity of communication in animals is linked to their social structures and the need to coordinate behavior within their groups.
Humans have a dual desire to set themselves apart from animals while also wanting to connect with them. This fascination stems from a historical acceptance of animal communication, which was later dismissed during the Enlightenment as humans sought to establish their uniqueness.
Sound is effective because it travels well in the atmosphere, can go around obstacles, and is preserved over long distances. This makes it a reliable way for animals to communicate across vast landscapes, such as wolf howls or dolphin whistles.
Describing animal sounds is challenging because it requires the reader to imagine the sound without hearing it. Kershenbaum addressed this by including anecdotes from his fieldwork and using spectrographic representations, which visually depict sound patterns similar to sheet music.
Wolf howls focus on pitch modulation, with energy concentrated in a single frequency that rises and falls. In contrast, human speech relies more on amplitude modulation, where the varying amplitudes of different frequencies carry most of the information.
Both wolf howls and dolphin whistles are long-range signals that use pitch modulation to convey information. When slowed down, a dolphin whistle sounds remarkably similar to a wolf howl, highlighting their shared evolutionary basis for long-distance communication.
Dolphins use whistles that are information-poor channels, meaning they can't convey a lot of information. While they do have other forms of communication, their primary whistle system lacks the complexity and structure needed for a true language like human speech.
Hyraxes use vocalizations to display their fitness to potential mates and rivals. Their songs are not random but follow a learned syntax, suggesting that many animals understand the importance of sequence in communication, a trait often associated with human language.
Social complexity directly influences the amount of information in animal communication. More complex social structures, like those in dolphins, require more sophisticated communication to manage relationships and interactions within the group.
AI can be useful in analyzing animal sounds and identifying patterns, but it cannot translate animal communication into human language. Instead, it can help classify different types of calls and understand their functions, such as territorial or aggressive signals.
To understand animals better, we must stop projecting human traits onto them and instead focus on their communication for their own adaptive purposes. This approach allows for a more accurate and satisfying understanding of how animals interact and function.
Zoologist Arik Kershenbaum has spent his career studying animals and how they communicate in the wild. In his book Why Animals Talk: The New Science of Animal Communication, Arik takes a deep dive into the various forms of communication, from wolf howls to gibbon songs, to look at how different species get their points across, why they do it the way they do, and what insights they provide into our own use of language.
