The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.

** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**



Rule 2- Your post subject cannot be illegal or NSFW material.

Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding non-TIL posts.

Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.



Rule 7- You can't harass or disturb other members.

Idk, I was assured that pigs had a Chinny-chin-chin.

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.

"Not by the hair on my dick, fuckface!"

TIL chins are only chins because they stick out. I had always considered the front of a lower jaw to be a "chin".

[–] [email protected] 24 points 6 months ago

In other words some people really have no chin...

Of course we know why. So that evolution could result in the universe's most perfect being.

This is why it bothers me when artists add chins to animalistic characters. It looks so wrong. An example:

Like, shit. Cool character design but you gave the cat lady a chin. Cats don't have chins, why did you give her a chin?

[–] [email protected] 131 points 6 months ago (3 children)

They don't have opposable thumbs, go into night clubs, walk bipedally or have those wing things either, why is it the chin that bothers you?

That character is mostly a cat skinned human.

You're complaining about a chin on an anthropomorphic cat woman that only has 2 breast's instead of 6 to 8...

If I am not mistaken, according to the grammatical scrolls, having a chin makes everyone .. chinese

[–] [email protected] 11 points 6 months ago

More chins than a Chinese phone book.

If other animals don't have chins, they're using a weird definition of chin.

[–] [email protected] 35 points 6 months ago (2 children)

“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.

I figure walking upright made being hit from below more common, necessitating thicker bones to protect the very sensitive nerves of the jaw.

The "spandrel hypothesis" is the front runner explanation. Essentially we didn't evolve to have chins but rather evolved other things that are helpful, and the chin is a byproduct of that other evolution. Not harmful so it didn't get selected away, but not helpful.

Would you mate with somebody who didn't have a chin? Chins are sexy.

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.
