I once plotted some vowels from my family for a homework and my uncle said to me:
"I feel like my tongue is higher when I say 'i' than when I say 'a'"
AND I WAS LIKE: that's the point, ily.

And his vowels were amazing, the exact point.

It's a hypothesis of what will happen with the Khoisan and Bantu languages ​​based on Anthony Traill 1995 and Ladefoged and Maddieson 1996.

I'm sorry to disappoint you (?)

/b d g/ → /ʔb ʔd ʔg/

/ʔb ʔd ʔg/ → /ʔ͡ǀ ʔ͡ǁ ʔ͡ǃ/

Protoform:
bada → [ʔbaʔda] → [ʔ͡ǀaʔ͡ǁa]

And also saw the consonant shift.

I just know that has been studied in literature, but it isn't a minority language.

In here they wanted to demostrated that the archaism (morphosintactic) is relative and helped for normativization.

Is not what you asked, but maybe you can find more from this.

ABSOLUTELY! I already show it to my thesis director JAJSJAJA

I don't what was it. I played and guess thw word yesterday (missing one sound) an played another one from previous days, but is random. I took a screenshot and post it, but didn't try it. Look, this was the word yesterday. Almost get it

I've been studying this the last year and always miss just one sound, almost there.
I saw it on linguistics memes (I think) they post it on stories.

My phonology teacher loved it actually
