The central premise of this book is that humans miss the tremendous amount of communication that is going on among and between other species. We miss it because we think of communication in an extremely limited way that revolves around visual and auditory expressions of human style languages. It doesn’t occur to us that different senses (e.g. smell) or other activities (e.g. stinging or passing gases,) could be used to convey messages as overt as, “Don’t touch me!” to as complex as, “There are good flowers to the southeast, roughly four-hundred meters along this line” or “Watch out! Some beetles have started chewing on my bark.”
While one might still dismiss all this communication as extremely simple compared to the infinitely complicated endeavor humans have made communicating, it’s not all just warning signaling. Many species engage in a form of communication that most people would probably attribute to humanity alone, specifically, deception. There are female fireflies who cannot only send a mating signal to males of her species to engage in reproduction, but can send counterfeit signals of other species to attract a male of another species of which she can make a snack.
It’s also important to note that it’s not just the species most similar to us who communicate. There are chapters devoted to both unicellular creatures and plants, species that one might be surprised to learn are quite active communicators.
I found this to be a highly thought-provoking book for the nature-lover, and I’d recommend it for anyone who wants to expand his or her horizons with respect to what is being transmitted in the natural world on those cold and quiet days when it seems like not a creature is stirring, and yet there’s always something.
