What did you learn today? Share it with us!

We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.

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.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



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.

If you vocally harass or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

For further explanation, clarification and feedback about this rule, you may follow this link.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.

I read somewhere sometime ago that the theory that makes the most sense is that we evolved chins to take a punch, which animals besides our immediate evolutionary relatives do not do.

So we evolved chins as an evolutionary advantage over our immediate evolutionary relatives who would logically be competing for the same resources.

I'm gonna guess the same reason we have big knuckles/fists and men have facial hair. Fighting.

[–] Knuschberkeks@feddit.de 0 points 4 months ago (2 children)

How is facial hair beneficial in fighting?

[–] Lux@lemmy.blahaj.zone 0 points 4 months ago (1 children)

Its essentially padding to protect ur face

[–] Donkter@lemmy.world 0 points 4 months ago (1 children)

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.

[–] VindictiveJudge@lemmy.world 0 points 4 months ago (1 children)

When you're fighting human, sure, but our mane probably evolved before we were our own greatest predator.

[–] PythagreousTitties@lemm.ee -1 points 4 months ago* (last edited 4 months ago)

I like how people downvoted you on this. As if facial hair somehow evolved after recorded history.

Chimps fight way worse than humans.

Artificial Intelligence Analysis:

The chin is situated near the area where the tongue and jawbone interact during speech. It's possible that the chin provides a surface for the tongue to move against, allowing for more complex sounds and articulations. The development of language is believed to have occurred around the same time as the emergence of Homo sapiens. While other primates have similar facial structures, they don't possess a distinct chin. This suggests that the chin might be related to the unique demands of human language.

Bingo -- other animals don't have a chin because they didn't invent languages like humans did for communication, and thus the demands of speaking weren't evenly distributed.

Next time on interesting questions 104: Why did homo sapiens develop language when other animals such as Corvids did not?

[–] SPRUNT@lemmy.world 0 points 4 months ago (3 children)

This makes more sense than the need to put on pillow cases (which has been my prevailing theory up to this point), but your question about corvids intrigues me. Partially because I'm not entirely certain of what a corvids is.

Yet again proving Chads are the pinnacle of evolution

[–] Liz@midwest.social 0 points 4 months ago (2 children)

Everything alive today is the pinnacle of evolution.

[–] DannyBoy@sh.itjust.works 0 points 4 months ago (1 children)

A chihuahua is not a pinnacle of anything.

“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.
