I’d recommend things based on stuff they like to read/watch in other media, so I don’t have a single must-watch.
That said my initial picks would be Fullmetal Alchemist: Brotherhood, Spy x Family, Kimetsu no Yaiba, Nichijou. Perhaps Log Horizon? EDIT: Uzumaki for people who are into suspense/horror.





















My take is that cetacean communication is, as far as we’ve analysed and attested it, proto-linguistic: it shows some of the features you’d expect from Language¹, but not the complete package.
This case is a good example. It’s showing low order units equivalent to phonemes; but it isn’t showing all that recursive “use blocks to build blocks” structure we see in Language e.g. [gestemes² | phonemes] building morphemes, morphemes building words, words building clauses, clauses building sentences, sentences building utterances, all of those to convey meaning.
Now let me point out some issues with the article. Mostly as correction.
Correction: “Sperm whales’ communication closely parallels aspects of human language, study finds”. Namely the abstraction of sounds into phonemes, or of gestual articulations into gestemes.
No, they don’t. In fact a lot of humans don’t have any sort of alphabet, with or without quotation marks. What they do have is a form of phonemes.
The distinction is important here because phonemes³ pop up instinctively for us, but an alphabet is a rather later learned development of some human societies. And the cetaceans in question likely have it instinctive too, like we did.
The video explains this better, but: note Mandarin has phonemic tone but not vowel length, and Latin has phonemic vowel length but no tone. For a better example of a language combining both, check Ancient Greek⁴. (For Slovenian it depends on dialect, some have tone⁴ and some don’t.)
I think a lot of the “underlying” structure might be actually shared across mammals: it’s the ability to abstract a variable signal into discrete units. The convergent evolution in this case would be only to use that underlying structure with the sounds produced by one’s own species.
One thing the article doesn’t mention is the potential for those being community-specific. As in: different vocalisations mean the same thing in different groups of sperm whale.
Side note this is fucking cool, and props to the researchers behind this. I wish the article did a better job conveying their findings. I’m reading the links provided by the article right now, and they look amazing.)
