Research into animal communication has revealed surprising complexities, particularly in species such as bonobos and whales. A study led by Mélissa Berthet observed bonobos in the Congo combining calls to form intricate phrases, suggesting a level of compositionality previously thought unique to humans. AI tools are increasingly employed to analyze and interpret these vocalizations, enabling researchers to uncover patterns that may indicate a form of language. For instance, sperm whales have been found to use a phonetic system with distinct sound patterns. This growing body of evidence challenges traditional definitions of language and raises questions about the cognitive abilities of non-human animals. While some features of human language remain unobserved in animals, the research suggests that the line between human and animal communication may be less distinct than previously believed.
