“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.
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.
Growing up half Japanese I could never help laughing at that story as chinchin means penis in Japanese, and I think everyone should share in this amusement.
I was gonna say elephants have chins too, as I’m re-watching old QI seasons and they brought up this fact, but upon further research their chins aren’t true chins with a bony protrusion.
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.
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.
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.
You see a chin area yes, but it is simply the bottom of the jaw. The human chin has actual muscle that goes below the jaw bone and can be moved ever so slightly which aids in facial expression.
As bigfig said, your cat probably doesn’t have a chin. That said, you might consider feeling your cat’s chin to see if it’s actually a chin and not just fluff or something.
If you feel a boney protrusion similar to a human’s chin, then you should unironically contact an evolutionary researcher. They might be fascinated about your cat having an actual chin as humans and only humans (not even neanderthals) are the only known chin-havers. Who knows, your cat might be the “missing link” between chinned and chinless humanoids.
Many animals, including most felids and canids, have a fifth toe (aka dew claw), which could potentially evolve into a thumb. You don’t normally see it on domestic dogs though, because if I’m not mistaken, it usually gets cut off when they’re a puppy due to it being weak and having a tendency to get caught on things.
Alternatively, there is polydactylism in cats, which can give them extra toes that can help them grab things (I’ve seen a video of a polydactyl cat using it’s extra foretoe like a thumb, though I can’t find it). It seems possible that, overtime, an extra foretoe like that might eventually provide enough of a evolutionary benefit for it to become a standard feature.
If cats evolved human-like intelligence, they’d absolutely have night clubs of some kind. That said, I’m not convinced that cats don’t already have human-like intelligence and aren’t just choosing to not use it, but that’s beside the point.
Walking bipedally is something a lot of smaller mammals can do as well, it just isn’t their normal mode of locomotion because their bodies aren’t currently designed for it. Going the evolution route again, however, and it’s possible that a species might eventually decide to stand up like humans did. Edit: I forgot about birds, dinosaurs and semi-bipedal mammals like the pangolin. Birds and pre-historic theropods walked on two legs, and pangolins have heavy tails they can use to balance on their hind legs so their forelegs are free to dig at ant mounds. So humans aren’t the only animals that walk on two legs.
The wing things are part of her clothing.
You’re correct that being bothered by a chin alone is strange, but,
A) people have weird things that bother them, sometimes illogically
B) I kinda look at anthropomorphic animals as being evolved from their real world counterparts, so I tend to rationalize things in regards to how they might have evolved. It makes it more believable for me.
C) iirc, in the context of the movie that specific character is from, thats actually someone’s VR avatar. As such, it makes sense to make human concessions like opposable thumbs, five fingers and toes (cats technically have five toes on each forepaw, four toes on each hind paw), walking plantigrade, etc. A chin seems like an odd concession to make. From the article, it doesn’t really give humans any really evolutionary advantage so it’s not like you’re gonna be unable to do something because you don’t have a chin; and based on what I’ve seen in the furry community, chins on anthros doesn’t really seem to have much of an aesthetic appeal either (otherwise nearly every fursona would have an obvious chin).
D) It just looks weird. Idk man, it just looks weird to me.
That said, I don’t tend to mind hybrids or mythical creatures like gryphons, dragons, dragon-cats, or whatever, so idk. It just looks weird to me and I guess the thing about humans being the only ones with chins is a explanation and justification for why I find it weird-looking.
