Video breaks down why early humans had naturally straight teeth and we don't

Thanks, innovation!

Technology isn't everything.

Crooked teeth is a very, very common occurrence in our modern world. Nine out of ten people have at least some misalignment going on in their mouths. Over 4 million people wear braces in the United States alone. I don’t know about you, but I can still feel the utter sticker shock from my own teeth-straightening journey. (I call it a “journey” so it feels a little more whimsical and less devastating.)

And yet, this is not something our ancestors dealt with. Like…at all. How could it be that no one experienced this normal modern-day conundrum in a time when we had exponentially less technological advancement?

As it turns out, technology might be the culprit, and a video from Ted-Ed explains it all.

The prevailing theory in the scientific community is that millions of years ago, when humans were hunter-gatherers, their teeth had to work extra hard to grind down seeds, fruit, meat, etc., and make them digestible.

When humans began incorporating tools, food was broken down before it even entered the mouth. It only became more refined and easier to chew with the introduction of agriculture, followed by the innovations of the Industrial Revolution.

In a relatively short amount of time (12,000 years), teeth were basically relieved of most of their “pulverizing duties.” And while teeth were initially able to adapt to the gradual evolution of culinary changes, things simply changed too quickly to keep up. Over time, jaws have reduced in size much more quickly than our teeth have, leading to overcrowding and some…unique dental arrangements.

This also helps explain why wisdom teeth are such a pain. By the time these final molars come out, there is simply no room left in the mouth for them. This is why many people need them surgically removed in order to prevent discomfort or infection.

This theory has been tested on animals like spider monkeys and lyraxes, who were given naturally tough foods and artificially softened foods. Sure enough, the critters with the softer foods also developed narrower jaws, and more crooked teeth.

Bottom line: this issue has a lot more to do with lifestyle than anything genetic. Which is why different people in different parts of the world don’t deal with dental crowding at all, and even have room for wisdom teeth. Knowing this might not stop us from eating softer foods—it’s certainly not gonna make me give up warm gooey cookies any time soon, perfect smile and zero cavities be damned—but it’s certainly something to chew on.

You can watch the full video, based on a lesson by dental anthropologist G. Richard Scott, below:

How to end hunger, according to the people who face it daily

Here’s what people facing food insecurity want you to know about solving the hunger problem in America

True

Even though America is the world’s wealthiest nation, about 1 in 6 of our neighbors turned to food banks and community programs in order to feed themselves and their families last year. Think about it: More than 9 million children faced hunger in 2021 (1 in 8 children).

In order to solve a problem, we must first understand it. Feeding America, the nation’s largest domestic hunger-relief organization, released its second annual Elevating Voices: Insights Report and turned to the experts—people experiencing hunger—to find out how this issue can be solved once and for all.

Here are the four most important things people facing hunger want you to know.

Family brings home the wrong dog from daycare until their cats saved the day

A quick trip to the vet confirmed the cats' and family's suspicions.

Family accidentally brings wrong dog home but their cats knew

It's not a secret that nearly all golden retrievers are identical. Honestly, magic has to be involved for owners to know which one belongs to them when more than one golden retriever is around. Seriously, how do they all seem have the same face? It's like someone fell asleep on the copy machine when they were being created.

Outside of collars, harnesses and bandanas, immediately identifying the dog that belongs to you has to be a secret skill because at first glance, their personalities are also super similar. That's why it's not surprising when one family dropped off their sweet golden pooch at daycare and to be groomed, they didn't notice the daycare sent out the wrong dog.

See, not even their human parents can tell them apart because when the swapped dog got home, nothing seemed odd to the owners at first. She was freshly groomed so any small differences were quickly brushed off. But this accidental doppelgänger wasn't fooling her feline siblings.

A teacher lists his class rules.

The world would be a much better place if humans weren’t so … human. We all fall short of perfection. Common sense is, sadly, not too common. And there’s one guy out there who always manages to screw things up when things start getting good.

Call it Murphy’s law. Call it the great “reason we can’t have nice things.” Call it entropy. It feels like a whole lot of pain could be avoided if we all had just a little bit more sense.

But what if there was one rule that we all agreed to follow to make everyone’s life better? What would this magical rule be?

A Reddit user who goes by the name P4insplatter came to this realization and asked the AskReddit subforum, “What simple rule would fix the world if everyone actually followed it?” They received dozens of simple rules that if everyone got behind would make the world drastically better.

You can't not sing this song.

The music of Queen has a profound visceral effect on everyone. Few pieces of art can cause complete strangers to put aside their differences and come together in song, but by golly, “Bohemian Rhapsody” is one of them. It would be cheesy if it weren’t so absolutely beautiful.

This pertains even to non-English-speaking countries, it appears. Recently, thousands of Harry Styles concertgoers in Warsaw, Poland, began cheering as those iconic beginning piano notes penetrated the air.

Movie critic Roger Ebert speaking his mind at the Sundance Film Festival.

It’s been ten years since the world lost Roger Ebert to cancer, and his voice is sorely missed. Ebert had a pure love of cinema, and even though he was a film critic in a sweater with a Pulitzer Prize, he wrote and spoke in a way accessible to every man.

He didn’t care if a film was a Hollywood blockbuster or art-house fare; what mattered was whether it deserved his highly-coveted “thumbs up.”

Ebert was an extremely gifted communicator whose interests went far beyond film. In his later years, he often mused about music, politics, and American cultural events with the same eloquence, thoughtfulness and wit.

Feeling nostalgic yet?

It seems like so many iterations of unfettered joy from our childhood haven’t made it to the modern age, and playgrounds are no exception.

Gone are the days of metal slides that scorched the derriere in the summertime, seesaws that doubled as human catapults and the notorious merry-go-rounds that separated the weak from the strong. Good old fashioned character building—safety be damned!

As it turns out, a few of these old relics are still standing. And footage of kids playing at one of these bygone parks is filling adults—particularly Gen Xers—with sweet nostalgia.

A couple shares why they decided to leave the United States.

Although it is difficult to tell if there is a trend of Americans moving out of the country, rough estimates show that around 8 million currently live in other countries—double the 4.1 million living abroad in 1999.

The most popular countries for Americans to move to are Mexico, Canada and the United Kingdom, in that order.

A big reason why some are leaving the U.S. is that an increasing number of employers allow people to work abroad. Others are choosing to leave because of cost of living increases and “golden visa” programs. Golden visas offer the chance to get a foreign residency permit by purchasing a house or making a significant investment or donation.
