WTF Fun Fact 12697 – Sharks Are Older Than Trees

by

Everything on Earth has evolved over millions of years to take its current form. So, in some sense, it can be hard to look back and make a firm division between a day when trees and sharks did and didn’t exist.

Still, there’s just really no comparison when you look at ever the more conservative numbers. Even if we go back to the species Archaeopteris, commonly considered the first species of “tree,” whose remains have been found in the Sahara desert, the now-extinct species “only” goes back 350 million years.

The numbers get kind of mind-blowing when you’re talking about evolution.

Sharks, on the other hand? Well, they go back 400 million years. And while that may seem like only a slight difference in number, 50 million years is A LOT of time (more than humans are really capable of conceiving).

We’re not sure which we would have guessed had come first – trees just seem older for some reason, but all evidence points to life starting in the oceans and not on the planet’s surface.

Sharks and trees aren’t something we compare very often, but both species have survived mass extinction events and hold secrets to the past that we can only dream of discovering.

WTF Fun Fact 12696 – Uranus’ Original Name

by

Uranus – everyone’s favorite planet. Or maybe when you hear the name, you instantly roll your eyes knowing that someone’s about to make a terrible joke.

Either way, many of us know that Uranus is the ancient Greek version of the god of the sky and heavens (and it’s technically pronounced ou-ra-nos, though some people even insist it’s urine-us rather than u-anus). But whatever. The point here is that the planet was originally named George.

And not just George, the Georgium Sidus (or Georgian moon/moon of George).

Until English astronomer William Herschel discovered the bright light was a planet in 1781, everyone assumed it was just another star, or perhaps a comet. The object had been seen before and was recorded in John Flamsteed’s catalog of stars (as “34 Tauri, the 34th star of Taurus the Bull”).

The Herschels were an incredible family of amateur astronomers. William’s sister, Caroline, may have been even more talented, and people knew it! In fact, Maskelyne wrote about the important role played by amateur astronomers right after Caroline discovered her first comet. (Caroline even got a job updating Flamsteed’s catalog of stars, the Historia Coelestis Britannica.)

Another fun fact? In the 1800s (and long before and shortly after), science could hardly be done without a rich person’s funding. Herschel wasn’t even considered to be a professional astronomer at the time – he also fell into the ranks of an “amateur.” In fact, the official Royal Astronomer, Nevil Maskelyne, still had to confirm it was a planet before it could be declared one. Even then, it was until astronomer Johann Elert Bode double confirmed it that the object was accepted by a planet by the scientific community (which is how you make it really official, not just “royal official”).

According to NASA, its mistaken identity as a star is understandable. The planet is extremely far from the sun and moves incredibly slowly (so much that half of it is plunged into ice-covered darkness for 21 years at a time). So you’d have to watch the object for decades to notice it even acts like a planet – that’s the kind of dedication required! It’s pretty much invisible to us now because of the light pollution the Earth emits.

But back to the George – Uranus thing.

William Herschel really wanted royal patronage (aka money) to fund his endeavors. So in order to gain favor with King George III, he used his fame as the person who discovered the first new planet since antiquity to advocate for the name George.

But George didn’t exactly fit with the naming scheme astronomers had going on at the time, which was all mythology-based. So in the end, it was Bode who got his way, naming the planet Uranus.

Of course, Herschel got the credit and the benefits that followed. And now we all get to tell Uranus jokes until the end of time (but it’s Bode we have to thank for that). – WTF fun facts

WTF Fun Fact 12695 – Male Mice Are Scared Of Bananas

by

We may have never noticed on our own that male mice harbor a fear of the humble banana. But scientists studying the fear responses of male mice to pregnant and lactating female mice made the connection.

Long story short, male mice can be very aggressive towards baby mice (or “pups), especially virgin male mice who see them as genetic competition. That’s why female mice have evolved to produce a compound, called n-pentyl acetate, in their urine that produces a stress and fear response in all male mice (but especially virgins).

Bananas enter the equation because they also happen to emit a compound that produces a fear response in male mice. They don’t contain n-pentyl acetate but rather isoamyl (or isopentyl) acetate.

Of course, bananas didn’t evolve to scare mice, that’s just a coincidence.

According to IFL Science:

“The team bought banana oil extract from the supermarket and placed it inside the cages of male mice to measure their stress levels, which increased significantly in response. The team believe that the stress response in the mice is similar to the stress response when about to engage in a fight.”

At least now we know one more strategy for getting rid of male mice! – WTF fun facts

WTF Fun Fact 12679 – OutHorse Your E-Mail

by

Visit Iceland recently got a weird idea. They’ve launched an out-of-office email service called “OutHorse Your Email” so you can outsource to a horse.

So, apparently, you can get a horse to write your OOO emails.

This was all brought about by a survey that found that 55% of vacationers check their email at least once and 60% said their bosses expected a response. (Of course, we’re not sure how bosses respond to horse emails, but that’s a survey for the future.)

Check this out:

It seems like a joke, right? Well, there’s a website and all you need to do is select a horse and put in your email information to generate your email.

According to IFL Science:

“The huge typing platform is then placed outside with the stunning backdrop of Iceland to complement the tip-tapping of typing horses writing the OOO emails of lazy humans. You can get your own emails written via the Visit Iceland website where Litla Stjarna Star from Hvítárholt, Hrímnir from Hvammi and Hekla from Þorkellshó are waiting to assist you.”

We’re sure your boss will be pleased. –  WTF fun fact

WTF Fun Fact 12677 – How To Survive A Date With A Spider

by

In many species of spiders, the last thing males do is mate. After that, they’ve done their job for the evolution of the species and are no longer needed. So females have evolved to simply eat them. They provide nutrients for the babies, after all!

It’s called sexual cannibalism and it’s one of the many facts of nature that we humans may have a hard time wrapping our heads around (or not, depending on your mate).

A few species have evolved to avoid this fate – for example, some may choose to amputate their own legs as a defense strategy in order to distract the females and get away (with the remaining legs, of course). In some sense, this makes sense since the female gets some nutrients and the male gets to hobble away with his life. It just seems a bit drastic from a human perspective.

Other spiders have learned to weave silk around the legs of the females before mating so they can make an easier escape afterward, which seems like a wise move as long as the female survives to produce her young.

The Philoponella prominens have developed a strategy whereby they use their two front legs to propel themselves out of reach of the females, getting away with all of their legs and their lives (if they hit the eject button in time, at least).

Since Philoponella prominens don’t have venom, the males who get cannibalized are in for a rough ride before death. The females produce over 400 feet of silk to “mummify” them, typically winding it so tight that they’re crushed and/or suffocated.

Not only are these spiders interesting for their actions but how they achieve them. Most jumping spiders launch from their back legs, so jumping using the front legs leads to some more interesting questions about the evolution of these creatures, especially since they don’t have muscles in those legs.

According to Smithsonian Magazine, the researcher who made this discovery noted that “one male was able to perform the behavior six times over the course of about eight hours, but was finally killed and eaten after his final performance–perhaps being too exhausted to spring himself to safety.”

WTF Fun Fact 12674 – The Man Who (Maybe) Died Laughing

by

Whoever said laughter is the best medicine probably never read about the death of the ancient Greek Stoic philosopher Chrysippus of Soli.

At the age of 73, the master of Stoic ethics and logic and leader of the Stoic School attended the 143rd Olympiad, which took place from 208 to 204 BC. At some point, a donkey came along and ate some of the figs he had with him. He found this hilarious, saying “Now give the donkey a pure wine to wash down the figs!” (Ancient humor doesn’t really translate well to the present, in case you haven’t noticed.)

The story is that Chrysippus laughed so hard as his own joke that he eventually fell to the ground and started foaming at the mouth. The people around him tried to help, but he died.

(Note that another story of his death is that he became dizzy and died after drinking undiluted wine at a feast.)

But the real question is, could the first story really have happened?

Technically, yes. You can die laughing.

Uncontrollable laughter can cause a heart attack, asphyxiation (which leads to a lack of oxygen), and can lead to a loss of muscle control causing you to collapse and fatally injure yourself. But it’s extremely rare.

However, there have been other stories of people laughing themselves to death. King Martin of Aragon is said to have laughed to death upon hearing a joke by his favorite court jester in 1410 (though indigestion seems to have played a role). Pietro Aretino apparently died by suffocation while laughing in 1556. And reports say that in 1660 a Scottish aristocrat, Thomas Urquhart, laughed so hard at hearing that Charles II was king, that he died laughing. And there are more modern cases too.

Do we believe them all? No. But it’s not impossible. –  WTF fun fact

WTF Fun Fact 12673 – What’s In A (Cat’s) Name?

by

In unsurprising news, there’s more evidence that cats don’t care about something.

Japanese researchers did a small study (which is really all you can do when cats get involved) and found that cats seem to recognize the names of their feline housemates. However, they still don’t give any indication of recognizing their own. Whether it’s because they just don’t care is something we’ve yet to figure out.

Why should we even care what words cats recognize? Well, IFL Science put it in context the best: “Birds with vocal cords that can imitate our own can learn a variety of human words, and it’s argued some know the meaning, rather than merely mimicking. Apes taught sign language also understand the meaning of words, and more recently dogs have been found to be able to learn up to 12 toys’ names in a week – but what about cats?”

In other words, we do all of this behavioral research on animals and find these fascinating signs that, in some sense, they can organize the world in ways similar to our own. So why not take a look at these abilities in some of the most common pets?

The research was conducted by Saho Takagi, a PhD student at Kyoto University who published the results in the journal Scientific Reports. The research team tried an experiment with domestic cats living in a 3+ cat home as well as residents of Japan’s famous cat cafes.

The study does rely on one important assumption (but if you know anything about science, you know that this is often the case since that’s where we start in order to help prove things). The assumption is that like other animals, cats stare longer than normal when they are surprised by something. In this case, hearing a name they recognize.

So the team spoke to the cats and said the names of their fellow resident cats to see if they would get a reaction. And they did, at least when the cats didn’t just run off in the middle of the experiment (and one did).

But what’s interesting is that this only happened in households, not in cat cafes. And in cat cafes there tends to be a lot of turnover from adoptions (and a lot more names to remember). So it may be that the cats in those cafes never hear a name enough time to have it ring a bell.

Apparently, the cats only reacted to the spoken names. Seeing their feline roomies’ photos on a laptop didn’t have any effect. Also, hearing their own names had no effect.

There were only 19 cats involved in the study, so it’s right to be skeptical. But that’s where we often start in science. The study still showed there was statistical significance to the results, and that’s typically a sign that further research can continue until there’s enough evidence to constitute some kind of “proof.”

In the meantime, just take it as a sign that your cat ignoring its name is not necessarily them blowing you off. They may just not be able to recognize that a name belongs to them. Or they just don’t care.

IFL Science explains this is not Takagi’s first cat study: “Last year she was first author on a paper exploring the feline capacity to map the spatial location of their person or a familiar cat. Takagi and co-authors reported the cats showed surprise when speakers broadcast the voice of the person who feeds them, despite that person’s absence. The same reaction did not apply to recordings of familiar cats’ vocalizations or unrelated sounds. Previously she studied cats’ understanding of the law of physics.” –  WTF fun fact

WTF Fun Fact 12655 – Alexander the Great and His Horse

by

King Alexander the Great spent his entire adult life trying to conquer the world on behalf of Macedonia, and by his side, nearly the entire time was his horse, Bucephalus.

The ancient writer Plutarch wrote much of what we know about the life of Alexander, including the story about how the 12-year-old future king won his noble steed.

A horse dealer tried charging Alexander’s father a very high sum for the horse (to be fair, his father was King Philip II of Macedon). No one had seemed it a good deal since the horse could not be tamed. But young Alexander saw some potential and made a deal with the horse seller – if he could tame it, he could keep it. If not, he would pay the high sum.

Of course, we know where this story goes – Alexander subdued the horse and then rode it into nearly every battle for decades until the horse died during a campaign in India.

As someone who felt he had the right to conquer the world, Alexander left his name all over it, including over 70 cities named Alexandria.

But he loved his horse Bucephalus so much that when it died in 326 BCE, he named a city Bucephala.

The ancient writer Pliny the Elder also wrote about the event:

King Alexander had also a very remarkable horse; it was called Bucephalus, either on account of the fierceness of its aspect, or because it had the figure of a bull’s head marked on its shoulder. It is said, that he was struck with its beauty when he was only a boy, and that it was purchased from the stud of Philonicus, the Pharsalian, for thirteen talents. When it was equipped with the royal trappings, it would suffer no one except Alexander to mount it, although at other times it would allow anyone to do so. A memorable circumstance connected with it in battle is recorded of this horse; it is said that when it was wounded in the attack upon Thebes, it would not allow Alexander to mount any other horse. Many other circumstances, also, of a similar nature, occurred respecting it; so that when it died, the king duly performed its obsequies, and built around its tomb a city, which he named after it” The Natural History of Pliny, Volume 2, translation by John Bostock, Henry Thomas Riley.

WTF Fun Fact 12649 – A Considerate Thief

by

A thief in Texas stole a lawnmower, but the strangest act caught on camera wasn’t the theft itself but rather the footage of him mowing the victim’s lawn before he took off with the equipment.

He mowed both the front and the back!

The Port Arthur Police Department said Marcus Hubbard stole the lawnmower on April 1, but the theft was no joke. Hubbard eventually did make off with the mower. But police arrived on the scene as he was making off with the stolen property and he abandoned it during his attempted escape.

They’re still looking for Hubbard at this point, so secure your mowers if you live in the area!
