Study Finds 300-Million-Year Gap Species Share Zipf’s Law in Song and Speech

Summary
Science Advances researchers found Bengalese finches and humpback whales structure vocal sequences with the same statistical pattern seen in human speech, including Zipf’s law linking frequent chunks to shorter forms.
Song data from Bengalese finches across several learning stages showed chicks acquire coherent note sequences from parents and peers in ways that mirror how human infants learn language.
The team said that patterning makes complex communication easier to learn and helps transmit it across generations, pointing to cultural learning—not just species-specific ability—as a driver of sophisticated signaling.
The result extends earlier finch findings by adding whale-song parallels, suggesting traits long treated as uniquely human language features may be more broadly shared across evolution.
