Understanding Animal Subjectivity Through Their Languages

Review of the book Animal Languages: The secret conversations of the living world by Eva Meijer.  

Damn, I didn't know most of what Eva covers in this book! Thank you 

Several years ago, there was big news: Dolphins call one another by name. Like humans, they all have a unique sound that they use to introduce themselves to new dolphins and to call one another. Dolphins are far from the only animals that have names. Parrots receive a name from their parents. Squirrel monkeys have a special “chuck” sound for each individual. Bats have names that they use to call one another so that they can stay together in the darkness. This can be particularly useful in a big group. A name is handy because it allows you to call someone else and to indicate that it is you who is coming.

Like cats, snakes have a Jacobson’s organ. Located in the roof of the mouth, this is an organ of chemoreception that is part of the olfactory system, which these animals use to smell. Their tongues capture scent particles that they place in the Jacobson’s organ, which has two openings, allowing them to smell the world in stereo. Snakes use this to find both predators and prey, and to communicate with other snakes. The trail that their body leaves behind and the air that they pass through contain pheromones with information about their gender and age, and whether they are pregnant. Young snakes follow this trail to find the location of the shared hibernation space. Puff adders, venomous snakes found mainly in southern Africa, not only leave behind scents for others to follow but also camouflage their own scent in order to deceive predators. Snakes also communicate by touch, and some cobras make low growls.

There are problems with the mirror test though: First, there are some animals who do not mind having a sticker on their skin. Second, in some cultures looking at yourself in the mirror is not good form. Third, it is not that suitable for animals whose other senses are more important than sight.

To start with the first point: Elephants use mud to keep cool and to prevent itching, so they often do not object to a little thing like a sticker on their skin and therefore score badly in the mirror test, in spite of their intelligence and socially minded attitude. We find the second, cultural aspect in gorillas, who are social animals and assumed to be self-aware, but they are naturally shy and long eye contact is not common among their kind, so they too score badly on the mirror test. The same applies, incidentally, to children from some non-Western cultures. Out of 82 children from Kenya, only two passed the test, whereas Western children pass the test almost without exception — clearly the difference here is cultural, not cognitive. Thirdly, the test is also not very suitable for animals whose sight is not good. Dogs are more focused on scent than on sight, so animal ethologist Marc Bekoff came up with the yellow snow test, a variation on the mirror test. Dogs live in a universe of scents, which inspired Bekoff to carry out an experiment in which he collected pee from the snow and investigated how his dog reacted. The dog in question, Jethro, spent considerably less time sniffing his own pee than that of other dogs, so he was clearly reacting differently to the scent profile of other dogs than to his own.

These examples show us that there is more going on in the social lives of animals than we may think. Looking at their languages can help us to better understand their inner lives. However, as the mirror test demonstrates, there are also problems with research methods that are based on human capacities: Human bias distorts how we view other animals. Similarly, if we only study the languages of other animals on the basis of how much they resemble human language, many animals will not fare well. In order to move beyond anthropocentrism, power relations in research need to be taken into account, and we need to develop new research practices together with other animals. In this process, existing concepts such as language can be a starting point.
