Sperm whales’ communication closely parallels human language, study finds

Not only do sperm whale have a form of “alphabet” and form vowels within their vocalizations but the structure of these vowels behaves in the same way as human speech, the new study has found.

The structure of the whales’ communication has “close parallels in the phonetics and phonology of human languages, suggesting independent evolution”, the paper, published in the Proceedings B journal, states. Sperm whale coda vocalizations are “highly complex and represent one of the closest parallels to human phonology of any analyzed animal communication system”, it added.
