Human language and primate vocalizations share features like joint action and combinatorial cognition, suggesting an evolutionary link. These commonalities indicate that key aspects of language evolved from ancestral primate communication systems.
Area of Science:
- Comparative psychology
- Evolutionary linguistics
- Neuroscience
Background:
- Human language and nonhuman primate vocal communication exhibit notable similarities.
- These shared features span joint action, neural underpinnings, and cognitive processes.
Purpose of the Study:
- To explore the evolutionary origins of human language by comparing it with primate communication.
- To identify shared features that may have served as a foundation for language evolution.
Main Methods:
- Comparative analysis of human language and primate vocalizations.
- Examination of shared neural mechanisms and cognitive processes, including discrete, combinatorial cognition.
Main Results:
- Both human language and primate communication involve joint action and similar neural systems.
- Discrete, combinatorial cognition is a shared feature, suggesting common evolutionary pressures.
- Ancestral primates likely evolved similar perceptual, communicative, and cognitive systems in response to social challenges.
Conclusions:
- Shared features between human language and primate communication point to a common evolutionary foundation.
- Many distinctive features of human language were likely present in ancestral communication systems.
- Understanding primate communication offers insights into the evolution of human language.

Higher Mental Functions of the Brain: Language
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
