It’s pretty clear that there are some grunts/vocalizations that are shared amongst all humans (and possibly primates) these would yes/agreement, no/disagreement, and question mark/surprise those aren’t language dependent. I’m not sure if it’s actually convergent evolution like the research paper implies my bet would that these predate humans by quite a bit, and some languages have a stronger onomatopoeic relationship between the base grunts and their question word. Even in English ‘What’ has the basic huh in it, wha/ha it wouldn’t surprise me if the T was added to make it more distinct or allow for more tonal information be passed along such as surprise, displeasure, disappointment and even anger. My non-linguistically educated opinion is that huh and and other grunts like a-ha (not the band) are probably much older than humans and they are universal just as female copulatory sounds are in humans and other primates (there is more to girls moaning in bed than just pleasure). https://en.m.wikipedia.org/wiki/Female_copulatory_vocalizations https://en.m.wikipedia.org/wiki/Female_copulatory_vocalizati...
