Is language a uniquely human characteristic, or do we share linguistic foundations with other species? This article, based on the work of Cédric Sueur (2023), explores the similarities and differences between human language and animal communication systems. Drawing on recent research, it offers a fresh perspective on this question, while revealing the complexity of animal interactions. A captivating journey into the heart of language sciences and zoosemiotics.
Language has long been seen as the cornerstone of humanity, a characteristic that distinguishes humans from other animal species. However, as science explores animal communication systems, this view is becoming more nuanced, revealing a fascinating continuum between human and animal linguistic abilities. In this article, we will examine these similarities and differences in depth, highlighting the unique elements of human language and the complexities of animal communication.
The specificity of human language: Between abstraction and flexibility
Humanity is distinguished by its ability to articulate complex ideas through language. This capacity rests on three main pillars: an elaborate grammar, the use of abstract symbols, and creative flexibility. These foundations allow humans to express abstract concepts such as philosophy, religion, and science, as well as to develop narratives and myths. This linguistic richness contrasts sharply with animal communication systems, often perceived as limited to concrete signals and immediate interactions.
However, it would be a mistake to consider these characteristics as exclusively human. The dance of bees, which conveys precise information about the location of resources, or the sophisticated songs of cetaceans, demonstrate a surprising communicative complexity in the animal kingdom. These systems, while far removed from human language, illustrate a certain flexibility and an ability to process spatial and temporal information.
Traits shared between humans and animals
Despite these similarities, significant differences remain. One of the major distinctions lies in the animals’ inability to communicate about abstract concepts or events distant in time. Animal communication systems appear largely anchored in the present, although intriguing exceptions, such as the delayed calls of orangutans when faced with predators, raise questions about their cognitive potential.
Furthermore, animal syntax, while impressive, remains far less elaborate than that of humans. Songbirds, for example, follow strict rules to compose their vocal patterns, but these rules lack the hierarchical and recursive complexity that characterizes human languages.

The perspectives of zoosemiotics
Zoosemiotics, an interdisciplinary field dedicated to the study of animal communication systems, offers a new perspective on these questions. It explores how animals use various signals to interact, not only with each other, but also with their environment. By studying these interactions, researchers decipher subtle mechanisms and discover surprising similarities with human languages.
For example, regional dialects in certain bird species or vocal variations in cetaceans reflect a cultural dynamic similar to that observed in human communities. These observations enrich our understanding of animal cognitive abilities and invite us to reconsider our perception of the boundaries between humans and animals.
Towards a re-evaluation of anthropomorphism
One of the main criticisms of animal language research is anthropomorphism, which involves attributing human characteristics to animals. While this approach carries risks, it has also spurred major advances in our understanding of non-human communication systems. Work on dolphins, primates, and parrots, particularly those that have learned to use symbolic systems, illustrates this dynamic.
It is essential to approach this research with caution, recognizing the limitations of analogies between humans and animals. Animals do not “speak” like us, but their communication systems are often far more sophisticated than previously thought.
Conclusion: A continuum between species
Language, whether human or animal, reveals a fascinating diversity of expressions and meanings. Rather than seeking to establish a strict dichotomy, it is more instructive to consider a continuum where communicative abilities vary according to the needs and environments specific to each species. This perspective broadens our understanding of nature and invites us to rethink our place within the living world.
