Linguistic anthropology is a branch of anthropology that explores how language influences social life. One of its subfields concerns understanding animal communication systems and comparing them to human language .
Introduction to Animal Communication Systems
Animals use a diverse array of communication systems, which include visual, acoustic, chemical, and tactile signals. These systems have evolved to convey a range of messages such as potential threats, location of food, and readiness for mating. The complexity and intricacy of these systems often parallel the complexity of their social structures .
Primary Communication Modes
- Visual: Animals use body language, postures, color displays, or bioluminescence.
- Acoustic: Vocal or mechanical sounds, used by a broad range of animals including birds, mammals, insects, and amphibians.
- Chemical: Pheromones or other chemical signals, common in insects and mammals.
- Tactile: Physical touch, used in many primate species, and in social insects like ants and bees .
Comparing Animal Communication Systems and Human Language
While animal communication systems are complex, most linguists and anthropologists agree they lack certain characteristics that define human language.
Unique Features of Human Language
- Arbitrariness: There is no intrinsic connection between words and their meanings.
- Productivity: Humans can produce an infinite number of sentences using a finite set of grammatical rules.
- Displacement: Humans can talk about things that are not present, including past and future events.
- Cultural transmission: Language is learned socially, not biologically .

Evidence of Language in Animals
However, research in the past few decades has presented intriguing evidence of language-like phenomena in certain animals.
Primate Language Research
Experiments with apes, particularly with chimpanzees and bonobos, have shown some capabilities for sign language and symbol usage. The famous case of Koko the gorilla is an example where the subject purportedly learned over 1,000 signs of American Sign Language.
Research on avian communication, especially songbirds and African Grey parrots, has also provided fascinating insights. African Grey parrots, like Alex, demonstrated an understanding of concepts like number, color, and shape, challenging the uniqueness of these aspects in human language.
Dolphins, with their high level of intelligence and sociality, have been found to possess signature whistles, suggesting individual names. This study indicates an element of arbitrariness, a feature of human language.
Delving Deeper: Syntax and Semantics in Animal Communication
While it is clear that animal communication systems often lack many of the features found in human language, there have been surprising discoveries regarding the presence of syntax and semantics in some species.
Syntax in Birdsong
Birdsong, one of the most well-studied forms of animal communication, has been found to exhibit elements of syntax. The Bengalese finch, for example, has been shown to use specific rules to sequence its song elements, demonstrating a form of syntax.
Semantics in Prairie Dog Communication
Prairie dogs have a complex alarm call system, with different “words” for different types of predators and descriptive information about individual features of predators. This communication shows evidence of semantics, the aspect of language concerned with meaning.

Animal Communication and Evolutionary Linguistics
Insights from animal communication studies are pivotal to the field of evolutionary linguistics, which seeks to understand the origins and evolution of language. The fact that certain animal species exhibit some language-like features might suggest these traits as stepping stones in the evolutionary development of full-fledged language in humans.
The Role of Anthropology in Animal Language Studies
Anthropologists play a crucial role in the study of animal language, adding a unique, cross-cultural perspective to this multidisciplinary research. Linguistic anthropology, specifically, can contribute by applying theories and methodologies from human language research to the study of animal communication systems.
Conclusion: The Complexity and Enigma of Animal Language
The exploration of animal communication systems underscores the incredible complexity of these systems. Yet, they are distinct from human language in key ways. Further research is crucial for a deeper understanding of the nuances and complexities involved in animal communication systems.
As we continue this exploration, the lessons learned will not only shed light on the evolution of human language, but also help us to appreciate the rich tapestry of communication that exists across the animal kingdom.
