Whales used to be land predators? Fascinating video explains how they're related to wolves.

But not all mysteries are solved.

Did seals get lost in the mix?

I think it’s pretty safe to say that when it comes to evolution, most people typically picture aquatic life forms sprouting legs then coming onto land … not the other way around.

Shockingly enough, a creature almost synonymous with the sea didn’t actually begin that way. And boy, is it a whale of a tale.

A mind-blowing video recently posted by PBS Eons reveals that whales were actually predatory land animals … the same ones that would later become wolves, specifically.

Yep, you read that right. Land animals. With arms and legs and everything.

To explain, we’ll need to go back 52 million years.



Before the warm and rainy Eocene epoch—the same time period that brought us the first horses and bats—whales looked more like the image below.

Something like a mix between a wolf and crocodile, if you ask me.

Yes, animals did move from the sea to the land, bringing us the first mammals. But then, over time, some mammals were like, "nah, it's that ocean life for me." Including some of these fellas.

These creatures first went into the water during the Eocene time period and eventually traded in their arms to become “sleeker and more streamlined,” while still holding onto their teeth.

By now they look less like a wolf and more like a murderous dolphin.

You're welcome for the nightmare fuel.

Cut to roughly 34-36 million years ago, and the species have diversified into the two major whale groups we see today: the Odontoceti (or “toothed whales”), which include sperm whales, orcas and dolphins, and the Mysticeti, better known as baleen whales … you know, those big guys with the filter-like “teeth” (aka baleen) that eat loads and loads of plankton?

The baleen whale’s evolution in particular has scientists a bit baffled, as there is no definitive evidence as to how, when or even why they began filter feeding in the first place. In fact, the first fossil of a mysticetes appeared around 36 million years ago, but baleen doesn’t show up until later, around 11 million years ago. Even the baleen’s oldest ancestor, the Mystacadon, according to the PBS video, showed no signs of baleen when researchers discovered it in 2019.

One theory: The cooled ocean current of the Oligocene epoch brought about an abundance of nutrients—specifically plankton—which made it more advantageous to bulk feed rather than hunt for single prey. This also helps explain the giant boom in different whale species.

Still, it’s all up for debate, and likely will be for a while since ancient baleen is hard to come by. Baleen, unlike teeth, is made of keratin, the same biodegradable substance hair and nails are made out of and, therefore, doesn’t fossilize well.

As the host cleverly quipped, “It’s basically like a big mustache inside the whale's mouth.”

Bottom line: We know a lot about nature, but there is still so much to learn.

If you’d like to find out more—like how the Mystacadon ate its prey by doing a super weird thing called suction feeding—you can check out the full video here:

Carl Sagan used a sliced apple to perfectly explain the fourth dimension.

The concept of the fourth dimension seems beyond human comprehension. As three-dimensional beings, we are unable to see beyond a physical object's height, width and depth. What else could there be? Even if you understand the concept, it is almost impossible to picture it in your mind, which is bound by the limits and realities of the physical world around us.

Enter Carl Sagan, revered as one of the greatest science communicators of his time. Perhaps best known for his research into extraterrestrial life, he was one of the first people to demonstrate that life could have existed on Mars. Sagan possessed a unique gift for demystifying complex scientific concepts, making them accessible and thrilling for the general public. If you never had the pleasure of watching him on television, you could imagine him as something of a Scientific Mister Rogers. Friendly, a wonderful storyteller, and always able to distill difficult lessons into their simplest form.

In 1980, on Episode 10 of the groundbreaking PBS show “Cosmos,” Sagan embarked on a mission to explain the seemingly impossible fourth dimension.


carl sagan, cosmos ,4th dimension, 3-D, 4-D, 2-D, physics, theoretical physics, math, science, space, spacetime, einsteinA great communicator and handsome, to boot.Giphy

Many of us have commonly heard of time being considered the fourth dimension. That's not so hard to understand — in order to locate an object in the universe, you'd need to know three dimensions of its spatial location and also the time during which it exists.

But there is also a more theoretical and harder to understand place, where all four dimensions are spatial. It is nearly impossible for any of us to comprehend... without the help of a gifted teacher.

What’s excellent about Sagan’s explanation is that he uses simple and relatable objects: an apple and a Tesseract, or a hypercube.

carl sagan, cosmos ,4th dimension, 3-D, 4-D, 2-D, physics, theoretical physics, math, science, space, spacetime, einsteinSagan explains that if an apple existed in a 2-dimensional space, anyone living in this "flatland" would only see a cross-section of it at a time.Giphy

"In discussing the large scale structure of the cosmos, astronomers sometimes say that space is curved. Or that the universe is finite but unbound," Sagan begins. "Whatever are they talking about?"

Yeah, this guy gets it.

Sagan then goes on to explain how a two-dimensional being living in a flat world would perceive a three-dimensional object like an apple.

Watch his full explanation here. It's hypnotic and entertaining and incredibly enlightening.

- YouTubewww.youtube.com


“Imagine we live in this ‘Fllatland’/2-D plane with no concept of ‘up’ or ‘down.’ Then along comes a 3-D object like an apple. We do not even notice it until it crosses our plane of existence — and even then, we have no idea what the apple is,” Sagan explains. “We see only a fragment as it passes through our plane. There is no way we can comprehend the 3-D quality/dimension of the apple, because it is more than we can understand. We only have the evidence of what has passed through our plane.”

To further demonstrate, Sagan stamps the apple into an inkpad and then onto the surface in front of him, which represents Flatland and all of its inhabitants. Inside Flatland, the apple exists only as its points of contact on the paper; or four small dots. He adds that as the apple passes through the 2-dimensional Flatland, its cross-section changes. So someone living in that plane of existence would experience the apple as an ever-shifting and rearranging set of shapes or objects. Wild!

Sagan then related this two-dimensional experience of the third dimension to how we might try to understand the fourth. To do so, he used the Tesseract, a four-dimensional cube, to demonstrate how difficult it is for us to perceive or visualize dimensions beyond our own three.

carl sagan, cosmos ,4th dimension, 3-D, 4-D, 2-D, physics, theoretical physics, math, science, space, spacetime, einsteinA tesseract can not exist in 3-dimensional space, but it can be approximated the same way a cube can be drawn on paper.Giphy

Sagan explains that the tesseract is a cube expanded into a 4th dimension, but "I cannot show you a tesseract because I, and you, are trapped in three dimensions." But what he can do is show us a 3-dimensional rendering of one. Just like a cube can be drawn and approximated (or cast a shadow) onto a piece of paper, a 4-dimensional tesseract can be imperfectly represented in 3-dimensional space. Still following?

At this point, Sagan is asking the viewer to expand their minds to understand the fourth dimension metaphorically. Though we cannot see it or even properly visualize it, that doesn't mean that the things we can see can't offer clues and lessons about the fourth dimension.

Studying 4-dimensional space can help in our understanding of the universe around us. Just because we see and experience only three dimensions doesn't mean that's all that exists. It's critical for physicists and mathematicians to be able to understand and map these theoretical spaces to better comprehend things we otherwise can not explain. Remember the ever-changing, rearranging set of shapes as the apple passes through Flatland?

Sagan’s demonstration of the fourth dimension isn’t just a wonderful explanation of a scientific idea that many of us find difficult to comprehend; it’s also a great example of how to teach complex ideas by combining clear explanations, everyday concepts everyone can understand, and brilliant storytelling.

Patrick the orangutan is a knot-tying master.

We've all heard the stories about how intelligent the great apes are, the great apes being a family of primates that include chimpanzees, orangutans, gorillas, and bonobos. There've been many famous cases of gorillas learning sign language, caring for kittens, or otherwise showing pretty astounding human-like behaviors.

Remember Koko, the famous gorilla who knew over 1,000 American Sign Language gestures? Her language proficiency may have been overestimated at the time, but she did help to completely change the way we view the intelligence and capabilities of the great apes. More recently there was Kanzi, a bonobo, who showed amazing proficiency at understanding and communicating with language. Kanzi once demanded the materials for s'mores, made his own fire, and roasted his own marshmallows!

The next famous great ape just might be Patrick the chimpanzee, a resident at the Metro Richmond Zoo.

In a video posted to TikTok, the zoo notes that Patrick just turned 34. His zookeepers gave him a royal green cloak to mark the occasion.

If he looks a little different than you're used to, it's because Patrick has especially pronounced flanges, or puffy cheeks. Not all males have flanges, but the ladies dig them. So those big old cheeks are just one more reason Patrick is a total stud.

In the video, we see Patrick wrap the cloak around himself and tie it into a perfect knot. It's absolutely astonishing to watch. It's maybe less impressive than some of the greatest feats accomplished by Koko and Kanzi, but there's something so human about the moment. It makes you view these animals in a completely different light. Just watch him pull the knot tight and then double-knot it to make sure it won't budget. Amazing!

Watch the viral moment here:

@metrorichmondzoo

Patrick turns 34, receives a royal cloak, and then ties the perfect knot - because even jungle royalty needs a signature look! 👑🦧✨ King behavior. #metrorichmondzoo #rva #orangutans #patricktheorangutan


5 million people viewed the video and were left in awe. They were also left wondering: What else can Patrick do?

Commenters had some interesting ideas:

"Now give him a fitted sheet and see what he can do"

"why do I feel like he could french braid my hair better than I can"

"Has anyone ever hugged him and if so what was it like?"

People were jokingly convinced that Patrick could speak, but chose not to:

"100% believe the conspiracy that they can talk but dont because they dont want humans to know"

Patrick isn't the first orangutan to tie knots. They've been observed doing it in the wild, and their weaving and tying skills are considered an extension of their nest-building behaviors.

But truly, what else can great apes do?

It was recently discovered that chimpanzees used medical plants to treat each other's wounds in the wild, in addition to using leaves to wipe themselves down after sex or pooping. This fits with the great apes well-known use of tools, but it also challenges the notion that humans are the only species that displays empathy and altruistic behaviors. Chimpanzees also have highly sophisticated memories and are capable of recalling specific events from years ago and even recognizing photos of themselves when they were younger.

Chimps and other apes have been proven to be able to perform basic math and some experts even say they have a photographic memory!

It's impossible to read all this and watch Patrick's intelligence on display without wondering whether great apes should ever be kept in captivity. They're so intelligent and capable of feeling, it seems cruel to keep them behind bars. But as conservation organizations have pointed out, many great apes simply can not be introduced back into the wild due to massive habitat loss. These creatures are endangered for a reason, and kudos go to the caring zookeepers who take care of them and help provide apes like Patrick with safe, enriching lives.

Middle-class families share how much they have in their savings accounts and it's eye-opening

"We make the most money we ever have and have zero savings. We live paycheck to paycheck and every month I don’t know how we get by."

Many middle class families are sharing that they have nothing in savings right now.

According to an April 2024 Gallup poll, 54% of Americans identify as part of the middle class, with 39% identifying as "middle class" and 15% identifying as "upper-middle class." That percentage has held fairly steady for years, but what it feels like to be a middle-class American has shifted for many.

Notably, inflation caused by the pandemic has hit middle-class families hard, with incomes not keeping up with cost-of-living increases. Housing costs have skyrocketed in many areas of the country, mortgage interest rates have risen to levels not seen since the pre-Obama era, and grocery bills have increased significantly. One government study found that the cost of living has increased between around $800 and $1,300 a month, depending on the state, since 2021, putting a squeeze on everyone, including the middle class.

How much money do middle-class Americans have in their savings accounts?

One woman shared that her family is just getting by and asked other middle-class people to "chime in" with what they have in their savings accounts.

@abbyy..rosee

somethings gotta give #savings #middleclass #relatable

"I swear, every paycheck I am putting money into my savings, but needing to transfer it back within a few days," shared @abbyy..rosee on TikTok. "My registration is due. My husband's registration is due. He needed two new tires, even though they had a warranty. That's $300. My oldest needs braces, he needs a palate expander, that's $120 a month. Not to mention groceries are $200 more a week. Forget about feeding your family great ingredients because who has $500 a week to spend on perfect ingredients to feed your family?"

She explained that her husband makes enough money that they should be able to live comfortably, and that she quit her job because the cost of daycare was more than she was making.

"At some point, something has to give," she said. "What is going on? How do I save money?"

People in the comments chimed in with their savings account totals and it was quite eye-opening. Many people shared that they have $0 saved.

"We make the most money we ever have and have zero savings. We live paycheck to paycheck and every month I don’t know how we get by."

"I think the middle class is 1 personal disaster away from bankruptcy."

"Y’all got savings accounts?!?! 😂"

"I used to freak out if I had under $10k in savings, now I’m happy when I have over $150. 😫"

"We make almost 100,000 a year with no savings!!!! It's always something!!"

"I'm lucky if we have $500-$1K for an emergency. Every single time we start saving, something happens: the vet, the cars, the kids... something."

"Savings account? I transfer money each paycheck but always end up needing to transfer it back. My husband makes great money too but we are scraping by."

"$803 but we have to pay a $750 deductible this week b/c my Husband hit a deer soooo… back at it 😭 It’s exhausting. Constantly draining it, refilling it, transferring."

Some people shared that they do have some savings, but several said it was because they'd had an inheritance or other chunk of money come their way. Many people shared that their savings has dwindled as increased costs have taken their toll. Some people gave lifestyle advice to save money, but most agreed that just the basics have gotten so expensive it's harder to make ends meet much less put extra into savings.

Thankfully, the inflation issue appears to be waning, but even just plateauing at their current financial reality isn't ideal for many American families. Middle class is supposed to be a comfortable place to be—not rich, but well enough off to feel secure. That's not how many middle class folks feel, though. Most Americans don't have anything close to the amount of money saved that is recommended across the age spectrum, but at least hearing that others are in the same boat is somewhat comforting.

middle class, cash, savings, family finances, dollar bills, An upset couple doing their bills.via Canva/Photos

Further, a 2024 study found that 37% of Americans can't afford an unexpected expense over $400, and nearly a quarter of them don't have any emergency savings at all. “Not all surprises are good, and people know it. The study suggests financial precarity at a time when household finances may be stretched due to rising prices and inflation,” says Rebecca Rickert, head of communications at Empower. “Life happens, and people are stressed about the surprise expenses that could tip them off-balance.”

It can be vulnerable to share your financial reality, but it's helpful to hear what other people are doing and dealing with so we all feel less alone when we're struggling. Perhaps if people were more open about money, we'd all be able to help one another find ways to improve our financial situations rather than lamenting our empty savings accounts and wondering how to change them.

Scientists are studying adorable "el chupacabra" rescue dog.

Dogs, like people, have a variety of features and personalities that help identify them from others. The combination of identifiable features becomes more vast among dogs as they breed with different types of dogs. Depending on the dog combination, you either get an expensive crossbreed like the golden doodle or what is typically classified as a mutt. But one dog named Nina may win the strange genetics award.

Nina was a rescue from Puerto Rico who was found abandoned. The poor pooch had no hair, but that wasn't because of a tragic accident; she is simply a bald dog. Nina's teeth are also...interesting. They jut out from her mouth making it look as if she might be part piranha. Her teeth make it nearly impossible for her mouth to fully close and, yet, somehow, she's simultaneously cute and terrifying.

Nina's not terrifying because she's done anything to warrant that label, but because she eerily resembles the mythical El Chupacabra. You know, the legendary animal at the center of Latin American folklore who allegedly kills livestock and drinks their blood. The description from people who claim to have seen the infamous Chupacabra varies. Some say the likely fictional creature stands on two legs and is huge while others say the animal is small and stands on four legs. But there's a strong theme that's developed between the sightings: the creatures looks dog-like, is bald or balding, and has sharp teeth seemingly placed wildly in its mouth.

Nina, of course, is neither fictional nor infamous; she's just a dog that looks kinda weird and no one knows why. DNA tests reveal she's 100% dog, but she's mixed with a lot of different breeds: Doberman Pinscher, Collie, Mountain Cur, Pomeranian, Chihuahua, Boxer, Chow Chow, Pit Bull Terrier, small Poodle, Labrador Retriever and German Shepherd. Maybe that's where she gets her unique looks from?

The problem is, all the breeds that show up in her DNA have hair, normal teeth, and eyes that close properly—all things Nina is lacking. In fact, her owners have to put artificial tears in her eyes due to the way her eyelids have grown. Scientists are fascinated by the unconventional way her genes have expressed, leading them to study the dog, with her humans' permission of course.

"Nina's health seems to be perfectly normal. We've gotten her tested for everything that we can imagine. She had a surgery called entropion and basically it means the eyelid hair, her eyelashes are digging into her eyes so they create these little ulcers on her eyes. So we got those fixed," Nina's mom tells GeoBeats Animals. "We have artificial tears that we have to put in her eyes because her eyes are, they don't shut. They just constantly stay open so we have to put those in a couple times a day."

While her owners joke with the vet that Nina is a Chupacabra, the truth is that she's just a weird looking mutt that scientists at Cornell University are trying to figure out, which requires bloodwork every six months. They're not sure if she has a congenital defect that causes her unique looks or if she simply lost the genetic jackpot. Either way, her adorably odd mug is stealing hearts all over the Internet. Her dog siblings also think she's pretty neat, giving her lots of extra kisses and snuggles.

Her owner added a last adorable detail, saying, "I feel like the other dogs kind of sense that she's a little different. They love to clean her, they treat her like a baby almost."

Apparently, losing your job without notice is an American phenomenon.

When you live in one country your whole life, it's easy to form ideas about what's "normal" and what's not. Cultural standards and accepted norms vary country by country, though, sometimes in dramatic ways that we wouldn't even think of.

That's why when someone asked, "What’s a very American problem that Americans don’t realize isn’t normal in other countries?" the answers were eye-opening. Seeing major aspects of American life that are not realities in other countries, especially other wealthy, developed nations, is wild. It's also a good reminder that we all have things to learn from one another and the things we might think of as impossible actually aren't.

from AskReddit

Lots to think about here as we ponder our quality of life and what's worth trying harder to change:

The cost of healthcare and medical bankruptcy

"Was in Germany with food poisoning. Drove myself to the ER. They were SHOOK when I told them I did. They then quietly told me you don't pay for ambulances there."

"I’ve never understood why police and firefighters get covered but we get a bill for ambulances. You'd think anything related to 911 is covered by our taxes."

ambulance ride, er visit, emergency room, medical costs. emergencyAmbulance rides can cost a pretty penny in the U.S.Photo credit: Canva

"First time I was living in Japan (didn’t understand the healthcare yet) and took a cab to the ER. They were so concerned and confused why I would do that. I was seen immediately, given IV, six medications on my way out: it only cost my like 60$USD. My friend apologized for how I had to pay so much as a non-citizen. I was shocked it was so cheap."

"I had a cancer diagnosis in 2019 and I joined an online support group. Americans were worried about the costs or losing their job because of missed days for treatment and doctors appointments. I'm Canadian. None of that stuff was any part of my worries. FYI, we got it all. I'm good."

"Yea the amount of GoFundMe’s for just like routine life medical s__t is wild."

"Breaking Bad would not have happened anywhere else but the US."

Prescription drug commercials

"I can’t even afford to go to the doctor. What makes you think I would book an appointment to see a doctor and ask for a drug that could give me 'blindness, or even death.'"

list of side effects, gif, America, drugs, problemsSide effects from drugs, GIF by Eternal FamilyGiphy

"I really love the ones that can give you 'potentially fatal disintegration of the perineum.'"

"This sports game brought to you by a prescription drug with a long list of horrifying side effects!"

Losing your job without notice

"That you can lose your job without warning. No notice period where you can get paid while looking for something else. Just getting thrown out of a workplace you've been at for years, with your belongings. And that this can lead to losing your right to proper health care because of insurance. Basically, no rights and no safety net. Only the rich seem to get severance packages."

"In my first job in Europe, I and the university screwed up majorly with my visa and I ended up stranded in Canada for a couple of weeks waiting to fix it. When I wrote to my boss to tell him what happened, I reassured him that I knew I'd probably lose my job over this etc. He was shocked that I even thought it was a possibility."

"Here in Ireland, there's been multiple instances where American-run companies think they can fire/lay off employees just like in America, and end up getting legal proceedings taken against them as a result."

"In Norway 3 months notice with pay is the standard."

No guaranteed maternity leave

"I still can't believe paid maternity leave is not a standard thing. And shit like women going back to work two weeks after giving birth. What is going on?"

"I know of a company that was bought out by an American company. They tried to enforce American rules on maternity leave. It did not work out well for them."

Pregnant woman, maternity leave, pregnancy, America, american parental leave policiesPaid parental leave is not guaranteed in the U.S.Photo credit: Canva

"The company I worked for denied my maternity leave and then approved it and then fired me for a system error that I begged them to fix for month. One that I didn’t cause. The maternity leave wasn’t even paid, it was just so I could return to work."

"I'm sorry, not an American. How are people meant to deal with raising a child without a maternity leave?"

Vacation time is seen as a luxury

"Getting time off. 2 weeks here feels like a lot. You work a bunch to get some more time off after x number of years. Other countries can get a month off no issue it seems like."

"I'm in the UK, I get 6 weeks plus bank holidays. I want more, asked for more, so my manager checked with HR. He now can approve another 3 weeks unpaid every year without needing further approval.

Also my American colleagues get the same benefits including 6 months paternity leave (full pay). He used it and he said his family genuinely questioned if he'd been fired and was trying to hide it. 😂"

"The law in France forces me to take 2 consecutive weeks between May and October of each year. After that I still have almost 6 weeks of vacation left on top of public holidays. You can take 3 weeks in a row without issue, but 4+ requires some negotiation, but it really depends on your job and company, for some it's a non-issue."

"I get 4 weeks Annual Leave a year + 2 weeks sick leave [in Australia]. They accrue and the annual leave must be paid out when you leave the company. I also get Long Service Leave (13 weeks at 10 years of service and 1.3 weeks every year after that.)"

"A friend of mine has like 5-6 weeks vacation per year in the US. Hasn't taken more than a week off within a year for years now. And I don't even think it's a full week as a block. He just takes 5 days max within the year."

Gun violence

"Guns. So many guns. So much gun violence. Just not an issue in other countries."

"Active shooter drills for kids in school. Bullet proof backpacks."

"One of the things that may surprise Americans, is that over in Europe and other places in the world, we don't do gun drills at schools or other places. We don't simply need to, because firearms offences are so low."

Protesters, holding signs, advocating unity, action, anti-gun sentimentsGun violence and active shooter drills are not the norm in other developed nations.Photo credit: Canva

"There are a lot of developed countries with a lot of guns. Canada, Switzerland, Finland, for example. Heck, even the UK has a lot of shot guns in the countryside.

The American culture of gun violence is unmatched in the developed world. It's not quite as bad as some Central America or under developed countries, but it's definitely an outlier in developed countries...I guess that is just America in general."

There are lots of wonderful things about the United States, but that doesn't mean there aren't places we could improve. Sure, some of these things are enormous, systemic things that are difficult to change, but knowing they're not "normal," only normal for Americans, might give us an extra push to advocate for what we really want as a people.
