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.

Also mistaken for fulgurite by the more naturalistically minded, apparently. Maybe most common in the Nordics, based on viking references?

Looks suspiciously phallic? Ritual of fertility it is

I love listening to researchers talk about places like Ur and Karahan Tepe and all the things we know about in between.

What I don't love is the very clear tendency to believe that people 10,000 years ago had the mental capacity of a frog.

No, I don't think the pit-like dwellings that don't have roofs were proof they were savages who lived under the open sky, I think in the TEN THOUSAND YEARS SINCE THEN the roof disintegrated. It's not a hard concept to put something over your head to stay out of the rain.

It IS however, hard to make a roof out of mud unless you know where to get special mud and how to cook it. They would have to use branches, leaves and long grasses to keep rain off, which definitely wouldn't survive 10 millennia.

So DID they have roofs? No idea, but trying to point at lack of roofs as "proof" of anything is kind of dumb.

Respect for the ones that straight up say "we don't know but it's speculated that..." though

Also it's disgusting to me how many times I've seen "because the people who found the artifact thought it was heretical/sacreligious/proves their religion wrong they destroyed most of it"

On the last part, you can see Jesuit exorcism markings on Tiwanaku and Inka statues. They tried to tear down temples too, but couldn’t figure out how to dismantle the foundations and first meter and a half off walls. So they used those to build European style dwellings on top of it.

[–] Dasus@lemmy.world 2 points 5 months ago

Pretty sure they had roofs some 10k years ago.

The oldest evidence of structures is from 476 000 years ago.

Whops I replied to the wrong comment

[–] niktemadur@lemmy.world 16 points 6 months ago

On a cultural television channel from Mexico, there was a weekly recurring host panel of five or six academics in different fields, all with their PhDs in literature, linguistics, history, political science, etc. La Dichosa Palabra (The Blessed Word) was the name of the show.

Anyway, one of the panelists always seemed to trace the etymology of every word to the name of such-and-such goddess from antiquity.

One or two times, ok sure, you get dazzled by the erudition. But when it happens over and over and over again with any word no matter how seemingly trivial, it all acquires a strong whiff of confirmation bias bullshit with nobody to call him out on it.

Ancient Rome, actually.

Everyone should read Motel of the Mysteries.

It's amazing to put into perspective how long both bronze and stone ages really took, especially compared to modernity. Human brains are not good at imagining large quantities or intervals, so it was all kinda smushed up into a folder labeled "past" in my head

[–] ogeist@lemmy.world 65 points 6 months ago (2 children)

To give some numbers, the last period of the stone age (Neolithic) lasted around 2000 years and the bronze age around 1600 years. No wonder they "forgot" what the stone age tools were.

[–] Potatos_are_not_friends@lemmy.world 34 points 6 months ago (1 children)

Someone pointed a temperature gun (for Covid testing) at me and for a brief moment, I forgot what they were.

When they're uncovered 100 years from now, they'll think we shot lasers at each other.

[–] Notyou@sopuli.xyz 47 points 6 months ago (1 children)

Don't we though?

[–] dumbass@leminal.space 10 points 6 months ago (1 children)

Yeah but they're lazers, totally different.

[–] _haha_oh_wow_@sh.itjust.works 6 points 6 months ago (1 children)

leminal.space

lol, I love that instance name

[–] dumbass@leminal.space 3 points 6 months ago (1 children)

Yeah in saw someone else using this instance and knew in had to join it.

[–] _haha_oh_wow_@sh.itjust.works 2 points 6 months ago (1 children)

Can relate: I signed up for my instance purely because of the name lol

[–] dumbass@leminal.space 2 points 6 months ago

Yeah that was the first one I signed up with, purely because of the name.

[–] PrimeMinisterKeyes@lemmy.world 3 points 6 months ago* (last edited 6 months ago)

Sidney Harris taught me otherwise.
EDIT: I just saw he turned 91 yesterday. Happy Birthday, Mr. Harris!

[–] ConfusedPossum@kbin.social 36 points 6 months ago (1 children)

Kurzgesagt did this video where they crammed all of Earth's history in an hour. Basically you look at a barren wasteland for most of the time until life finally goes macroscopic and then all of humanity happens in less than a second

I sat through the whole thing and it's still incomprehensible

[–] samus12345@lemmy.world 20 points 6 months ago (2 children)

It's gotten so fast that we now see significant changes in our lifetimes - cultural, technology, climate. For most of human history, it took many generations for any real change to occur.

Japan might be the record holder for fastest significant change, though. Feudalism to a modern industrial economy in a few decades.

[–] KevonLooney@lemm.ee 10 points 6 months ago

Please. The USSR industrialization speed run is unsurpassed. Peasants to the first artificial satellite in 40 years. Also, parts of Russia are still completely undeveloped today!

[–] TachyonTele@lemm.ee 4 points 6 months ago

Japan did it twice. They closed their borders between bouts of rapid modernizations.

[–] MataVatnik@lemmy.world 52 points 6 months ago (1 children)

I can't even remember why I bought the chives that are sitting in my fridge, we can probably give them a break.

[–] carbonari_sandwich@lemm.ee 42 points 6 months ago (1 children)

My conjecture is that the chives served a religious purpose.

[–] TachyonTele@lemm.ee 5 points 6 months ago

It's a sign! Repent!

[–] Hegar@kbin.social 32 points 6 months ago* (last edited 6 months ago) (1 children)

A lot of these hand axes may have had some kind of not-strictly-functional purpose during their heydey in the stone ages as well. Heaps of them show no evidence of wear or use and are noticably gorgeous - just really pleasingly shaped.

[–] Usernameblankface@lemmy.world 22 points 6 months ago (1 children)

Kind of like modern pickup trucks? Some get actual use, many more are just pretty and for the illusion of usefulness.

[–] Hegar@kbin.social 6 points 6 months ago (1 children)

Kind of like modern pickup trucks

Except nice to look at, yep!

Pick ups seem like a great example because they are so often a status/identify token.

[–] Usernameblankface@lemmy.world 4 points 6 months ago

I also don't find them particularly good looking, but their owners sure do!

I like identity token for trucks that never see truck use.

[–] Crashumbc@lemmy.world 24 points 6 months ago (1 children)

Not surprised, oral history...

Being able to write things down has to be one of the more important inventions.

I seriously suspect if dolphins and whales, ways of storing information they might be more intelligent than us.

[–] deft@lemmy.wtf 3 points 6 months ago

Agreed fish and climbing trees and what not
