To explore this, researchers put forward three basic tests: does a call pick out a single individual, does the call act like a symbol rather than a raw emotional signal, and do other animals treat the call as carrying the same meaning? Those criteria create a clear way to compare claims from studies of parrotlets, marmosets, elephants, and dolphins. Applying a common framework helps separate intriguing anecdotes from evidence that would reshape how we think about animal communication.
If animals meet these tests, the implications touch learning, social identity, and inclusion across species. Imagine social groups where names guide interactions the way they do among people. Follow the full article to see where current evidence falls short, where it points forward, and which experiments could reveal whether names exist beyond our species.
In recent years, several claims have been put forth suggesting that animals of different species address each other using receiver-specific calls that function as individual names. If accurate, this would demonstrate a capacity for symbolic social reference that has rarely been documented in nonhuman communication systems. To evaluate such claims, we propose three minimal criteria for identifying names: individual reference, symbolic representation, and shared meaning. We then review the evidence relevant to these criteria in the species for which name-like calls have been suggested: spectacled parrotlets, common marmosets, African elephants, and bottlenose dolphins. Together, these criteria provide a clear and theoretically grounded framework for exploring the use of name-like calls in nonhuman animals.
