I jokingly told someone recently the it should not be Homo Sapien - Intelligent Ape, but instead should be Should Have Know Better Ape. But what would that be? Homo?
FWIW, Homo means man; not ape.
Sapiens Beta Edition
To be further pedantic, “homo sapiens sapiens” means “the man who thinks about thinking,” to reflect our (supposedly) unique self awareness.
Which suggests the alternative might be the Latin for “the man who only thinks he’s thinking,” or some such.
Homu Stultus - “stupid man”
Homo-oops my bad
You could say Homo sophomori
I have no idea if ChatGPT gets its Latin right:
Got it! You’re looking for a Latin binomial in the format _Homo ___ that conveys the meaning “man who should have known better.”
Here are a few options, depending on the tone you want (serious, satirical, etc.):
Best All-Around Suggestion:
Homo debiliscientia
“Man of failing knowledge” or “man lacking the wisdom he ought to have had.”
- debilis = weak
- scientia = knowledge
- Implies a being who should have known, but didn’t due to weakness or failure of insight.
Homo oportebatscire
“Man who ought to have known”
- Based on oportebat scīre = “ought to have known.”
- This is slightly bastardized Latin for the sake of humor and binomial form, but reads well as mock taxonomy.
Homo debuitnosse
“Man who should have known”
- From debuit nosse (perfect of debere + know)
- Readable by Latin scholars and still fits taxonomic naming style.
Homo ignarusculpabilis
“Ignorant but blameworthy man”
- ignarus = unaware, ignorant
- culpabilis = blameworthy
Would you like it to sound more ancient/academic or more comic and biting, like a scientific name in a satirical essay or cartoon?
How about homo superedax - “over greedy”
Homo superbia, Arrogant man
Homo insolentia, Reckless man
Homo marginalis - Just barely smart enough to be sapient. Usually … would you believe … sometimes?
I realized that about an hour after I walked away from my computer. Should have known to double check what I was writing.
This might be a quibble …
Not sure how much it means “man” / “human”. In Latin homo means “alike” or “same as”. In other words, signifying the genus of critters like us. Yes, who are themselves called humans.
So maybe a quibble between “what it means” and “what it stands for”?
Homo = “same” is Greek. Homo = “man” is Latin.
Wow. TIL. Thank you.
Hombre! I thought it was obvious 
The context I’ve mainly seen that used was when it was popular to consider Neandertals a subspecies of Sapiens.
