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:

In a flurry of heavy headlines that constantly inundate our feeds, acts of good connect us back to our faith in humanity. Witnessing just one person go out of their way to make the world a better place is a powerful healing salve against apathy. It reminds us all of what we are collectively capable of creating. This is the philosophy that Upworthy wholeheartedly believes in, hence why we’re always sharing uplifting stories of people giving kindness, generosity and support to their fellow humans.

That’s also why we’re partnering with P&G, the maker of some of our favorite household products like Tide, Always and Pampers, to bring you the 2023 Acts of Good Awards, and celebrate the individuals who are giving back and strengthening their communities.

What will you create on your social media break? Share it at #MyVisionMySight.

True

If you’ve always lived in a world with social media, it can be tough to truly understand how it affects your life. One of the best ways to grasp its impact is to take a break to see what life is like without being tethered to your phone and distracted by a constant stream of notifications.

Knowing when to disconnect is becoming increasingly important as younger people are becoming aware of the adverse effects screen time can have on their eyes. According to Eyesafe Nielsen, adults are now spending 13-plus hours a day on their digital devices, a 35% increase from 2019.1. Many of us now spend more time staring at screens on a given day than we do sleeping which can impact our eye health.

Normally, you blink around 15 times per minute, however, focusing your eyes on computer screens or other digital displays have been shown to reduce your blink rate by up to 60%.2 Reduced blinking can destabilize your eyes’ tear film, causing dry, tired eyes and blurred vision.3

Unwritten rules poor people follow that may be surprising

Fantasizing about what it's like to be rich is something plenty of people do, especially if you'd classify yourself as poor. People make lists of the things they'd buy or businesses they'd start if they won the lottery, even if they don't play. But being poor comes with ingenuity.

Because you have little access to funds, which equates to little access to necessities, you get creative in ways to stretch a dollar. It also becomes glaringly obvious when someone didn't struggle with poverty by what they say or the things they do. Things that seem normal to them seem strange to you or vise versa.

In a compilation video posted on YouTube by TikTok News, a man wrapped in a blanket poses the question, "What's an unwritten poor person rule that rich people wouldn't understand." The replies didn't disappoint and if you grew up poor some of these will have you nodding your head in agreement. If you didn't, then you may be in for a bit of a surprise.

Taryn Collins, Jason Loger and their son Russell are living the "tug life."

A family in Northern California has found a way to beat the high price of rent and live a life of freedom on a 65-foot decommissioned U.S. Coast Guard tugboat. According to a recent story by South West News Service, Jason Loger, 37, and his wife, Taryn Collins, 36, bought the boat for $35,000 at an auction in 2019. Since moving to the boat, they’ve had a son Russell who’s two years old.

They purchased the vessel on their second date.

“When I first saw the boat in pictures I thought it was a floating tetanus shot,” Taryn said according to Metro. “But once I got in there and saw Jason’s love and his passion for it and saw the ability to move on water, I fell in love with the whole idea of it.”

The Visual Look Up feature on Apple iPhone

Have you ever been walking your dog around the neighborhood, noticed a pretty flower, and wondered what kind it is? Have you ever looked at your dog and wondered what breed they are? Well, a new feature on your iPhone called Visual Look Up provides you with information about plants, pets and landmarks while you’re on the go.

A lot of people don’t even know that this helpful feature exists. It became available with iOS 15, so if you’re running an older operating system, then you’ll have to update your iPhone or iPad to use the feature.

Here’s how the feature works:

  • Open a photo in full screen; the Visual Look Up button (an “i” enclosed in a circle with a small star on the left side) indicates that Visual Look Up information is available for that photo.
  • Swipe up on the photo or tap the Visual Look Up button.
  • Tap the icon on the photo or at the top of the photo information results to view Siri Knowledge and more information about the object.
