Peak humanity
The New Chad
“If you’re looking across all of the hominids, which is the family tree after the split with chimpanzees, there [are] not really that many traits that we can point to that we can say are exclusively human,” Duke University’s James Pampush tells Robert Siegel for NPR. “[T]hose animals all walked on two legs. The one thing that really sticks out is the chin.”
One of the most popular ideas is that our ancestors evolved chins to strengthen our lower jaws to withstand the stresses of chewing. But according to Pampush, the chin is in the wrong place to reinforce the jaw. As for helping us speak, he doubts that the tongue generates enough force to make this necessary. A third idea is that the chin could help people choose mates, but sexually selective features like this typically only develop in one gender, Pampush tells Siegel.
The spandrel hypothesis is as good a theory as any, but it too has its problems. It’s hard to find evidence to test if something is an evolutionary byproduct, especially if it doesn’t serve an obvious function. But if researchers one day do manage to figure out where the chin came from, it could put together another piece of the puzzle of what makes us different from our primate and Neanderthal cousins, Yong writes.
The dismissal of a sexually selected trait just because it usually is far more pronounced in one sex than the other seems extemely premature to me.
I would argue chins are actually already quite different between the sexes - to the point where people will have surgery to change their appearance if their chin doesn’t conform to societal ideals.
Sexually selected trait seems like an avenue of research that shouldn’t be so easily dismissed.
hard to find evidince
This is, like, an undergrad project.
-
work with the depressed grad student who is good at stats to determine the parameters of your experiment at the outset and calculate the number of subjects and stimuli for statistical power; pay in marking or research help.
-
get an appropriate number of headshots from undergrad males for stimuli, give them intro psyc course credit for participating.
-
work with mid-degree graphic design students to give all headshots 3 levels of chins (low, normal, emphasized), ensuring none are comical; the the psyc grad student signs off on the work as portfolio credit
-
have an appropriate number of undergrad cis-het women subjects rate a your lineup for attractiveness; intro psyc course credit for participation
-
analyze the results to see if low chin is selected less than normal or emphasized.
-
submit your research paper and results; get your 4th year class capstone. Grad student takes your work and adds it to their dissertation, you get a footnote.
I’m sure this has been done…
I don’t have a source on hand, but I’m sure that a pronounced chin has been found in studies as male attractiveness symbol

The one thing that really sticks out is the chin.
I see what you did there
I’m gonna guess the same reason we have big knuckles/fists and men have facial hair. Fighting.
How is facial hair beneficial in fighting?
Its essentially padding to protect ur face
But you ask anyone who knows anything about fighting and the first thing they tell you to do is to cut your hair short because it’s just an easy handle to grab on to.
When you’re fighting human, sure, but our mane probably evolved before we were our own greatest predator.
I like how people downvoted you on this. As if facial hair somehow evolved after recorded history.
It’s neither beneficial nor an inherent detriment.
It doesn’t provide enough padding to matter for anything, and the dangers of it bring grabbed are vastly exaggerated (been doing martial arts and grappling in one form or another since jr high, if you count a little wresting then, so over thirty years with breaks here and there, and bearded the entire adult time).
At best, blows will slide more and cut less, but not enough to really matter. At worst, having it grabbed hurts, which can be a bad distraction, but it isn’t so sturdy as to not be easy to escape. It either pulls loose if their grip is bad, pulls out if their grip is good enough, or makes sure their hands are easy to reach, and allows you an easy access inside their reach.
Every little pro has a con, and vice versa, with none of it being a deciding factor.
A ponytail is worse, and a braid worse than that.
Besides, anyone with a beard that isn’t just full mountain man is going to be oiling or otherwise treating their beard. This makes bare handed grips next to useless on them. And if you’re in a full contact sparring session, you’ll have other options to keep it from being a horrible thing.
Seriously. I have never once been tapped out because of my beard. I’ve never had any idiot during my years as a bouncer be successful in using it against me. Now, I have had to trim or shave it back because of having wads of it snatched out, but that’s still a very minor issue compared to the other things that can happen in a fight.
If anything, the fact that people tend to have this weird reaction to a big, bearded guy compared to just a big guy, you get in less fights in my experience outside of training or a job. Going places with a full beard, even drunks wouldn’t fuck with me the way they would other big guys. There’s a bit of some kind of reaction where people think a beard = tough sometimes. No clue why, just that it’s often enough to have noticed.
It’s slippery.
As in a signal of how manly a man truly is, comparative to still being a boy.
Edit: also, hair is counter productive in a fight, because it gives your opponent something to grab a hold of and use against you.
chin stab
Chimps fight way worse than humans.
Stop fighting chimps
I told them to break it up, but they didn’t. How else can I de-escalate? I’m mostly trained in bonobo conflict resolution.
😏
You gotta
throwfling your feces at them.Yeah Chimps eat the losers
They fight differently, we like to punch.
Useful in fighting as it helps protect the lower jaw and teeth?
But then again, it could simply be a trait we have developed over the millennia, and there is no deeper meaning to it.
I think this is plausible, also the fact that when you lean your head a little bit forward you expose the front of the skull which is the thickest part while the chin prevents people from punching your neck.
Well, you can’t take it on the chin if you don’t have one I suppose.
Yet again proving Chads are the pinnacle of evolution
Everything alive today is the pinnacle of evolution.
Nah, I’m of the view that evolution doesn’t grow upwards, but sudeways. We are at the edge.
A chihuahua is not a pinnacle of anything.
Dude, don’t disparage the chihuahua. They’re the pinnacle of anxiety; something many of us can relate with.
I figure walking upright made being hit from below more common, necessitating thicker bones to protect the very sensitive nerves of the jaw.
What else would I stroke while thinking? 🤔
But why did we evolve a hook & loop clasp to hold the top of our skull closed?
I hear some people are born with just a solid skull with no hinges, it makes me so uncomfortable.
It was a defense against the now extinct Brain Scooping Gorilla
TIL LeafyIsHere isn’t human after all…
Aliens
If other animals don’t have chins, they’re using a weird definition of chin.
Except for Cowboy Cerrone. No chin on him at all heh.
So humans are also the only animal that can hear chin music?
