Why only 20% of people can wiggle their ears and doctors say it's a 'superpower'

It's more than just a fun party trick.

Do you know someone who can wiggle their ears, either up and down and back and forth, but whenever you look in the mirror and try to do so, you flare your nostrils like a bunny, but nothing moves? According to Popular Science, only about one in five people can wiggle their ears, and it’s most likely not because they practiced all day in the mirror. For most people, it’s genetic.

In a recent video, Dr. Monica Kieu calls being able to wiggle your ears a “rare superpower.” Kieu is a board-certified specialist in facial plastic and reconstructive surgery in Beverly Hills and Newport Beach, California. “Moving our ears is a vestigial trait, meaning that it's a relic from our previous ancestors,” she says in a YouTube reel. “Although these movements help us localize sound, it doesn't really have much function.”

Why can some people wiggle their ears?

If you have a dog or a cat, you’ve noticed that when there is a loud noise in the house, their ears perk up and then, like radars, scan the home and beyond to find the location of where the sound came from and what it might be. As humans, we’ve lost the need for such sensitive hearing over millions of years, so the auricular muscles (those attached to your ears) have become weaker. They are now considered vestigial or something that either didn’t finish developing or, through evolution, has become useless.

The auricular muscles aren’t the only thing evolution has left us from the past. The wisdom teeth are left over from when humans had to chew a lot more raw food. The appendix was used to digest tough plants, and goosebumps are left over from when we had fur.

Those who can wiggle their ears have not just developed vestigial ear muscles; their brains are wired to allow them to do so. They still have neural pathways in their brains that enable them to move those muscles, while others may have lost them a few branches back on the family tree. According to Popular Science, significantly more men than women can move both ears at the same time.


How to wiggle your ears.

Do you dream of being able to wow people at parties and entertain small children by wiggling your ears? Daniel J. Strauss, a professor of neuroscience and neurotechnology at Saarland University Hospital in Germany, says it’s possible. "In a recent study, we provided visual feedback — some sort of display of muscular activation on a screen — which could help people 'train' specific ear muscles,” Strauss told Life Science.

Gillian Margonis, a popular TikTok user, claims she taught herself how to wiggle her ears while bored in high school. Here’s her step-by-step process for getting the wiggles going.

1. Notice when your ears move

If you feel a slight movement of your ear muscles when holding back a smile, those are the muscles you should focus on. "After you recognize when it happens, look out for it," Margonis says.

2. Focus on your newly-discovered muscles

"Try to use those same muscles and see if it makes your ear move," she said. "You're probably only going to be able to do one or two wiggles until you gain control of the muscle enough to wiggle your ears as much as you want."

I know my ears are big!!! thank u for 550k :-) ily

Engineering students created a life-size 'Operation' game—with a fun twist on the fail buzzer

The game trades in tweezers for tongs and the anxiety-producing buzzer for an audio meme.

Students at Washington State University created a life-size Operation game.

Anyone who has ever played the game Operation likely feels a teensy bit of anxiety just thinking about it. The experience of painstakingly trying to extract the Charlie Horse with those tiny, wired tweezers with a steady hand, only to accidentally touch the metal side and get the lightning-like jolt of the buzzer is hard to shake. That's the stuff of core memories right there.

But what if you had a humongous game board the size of a real human, with life-size bones and organs to extract? What if instead of tweezers, you had large tongs as tools to perform your operation? What if instead of Pavlovian-style fail buzzers, the game produced a much less traumatic womp womp womp sound when you mess up?

That's exactly what students in Washington State University’s chapter of the American Society of Mechanical Engineers (ASME) spent the past two years designing and producing—a life-size Operation game that's not only fun to play, but can help kids learn about the human body.

Students took on the project after Pullman Regional Hospital’s Center for Learning and Innovation approached WSU engineering professor Roland Chen about the idea. Chen took the concept to his senior-level design class and they created an initial plan, which was then passed on to the engineering club.

WSU senior Joel Villanueva, who served as a team leader on the project, tells Upworthy that approximately 15 students were involved in the game's creation over the two years it took to complete it. The project was quite complex as it involved translating the computer-aided design to a real table, creating multiple prototypes, figuring out the right level of challenge and making sure it was safe for kids to use.

In terms of gameplay, Villanueva says it's very similar to the original board game, but obviously much larger and with a few key differences. "We have tongs that aren't connected to wires, which was a safety concern, so we found a way to increase that safety factor," he says. "And it also has sound. So when it's triggered, a red light is emitted and an error sound is also emitted."

Villanueva says they didn't want the fail signal to be too alarming, which makes sense since the game was made for kids at the local science center. So instead of the buzzing of the original game, touching the sides of the organ or bone opening results in a sad trombone sound—womp womp womp wommmp.

The game is officially referred to as the Surgery Skill Lab and is now a part of the EveryBODY exhibit at the Palouse Discovery Science Center (PDSC) in Pullman, Washington. It's ultimately a learning tool, and Villanueva says they put the bones and organs in their appropriate locations in the body to help kids learn about human anatomy.

"We worked with the BMES [Biomedical Engineering Society] student section who created some fact sheets about the project," adds Villanueva. "For example, 'The heart pumps this much blood at a given time'—small fun facts like that."

The bones were 3D printed, then coated with silicone (so the tongs can grip them), and the soft organs were molded out of silicone using 3D-printed molds.

The game was unveiled at a Family Night event at the PDSC on January 19, so Villanueva and his team got to see how it was received.

"It was an eye-catcher," says Villanueva. "There were many kids playing with it and it seemed like they were having lots of fun with it."

Jess Jones, who is part of the education team at PDSC, tells Upworthy that there was also a real doctor at the exhibit during the opening to talk with kids about medicine. She says the game has been a hit with kids so far.

"They're loving it," she says. "The organs are 3D printed so they feel kind of realistic. The kids are loving the texture."

The project is a win-win for both the university students and the local community. The students got to put their engineering skills into practice using various software and technologies and also gained valuable life skills such as time management, documentation, leadership and more. And the community gained a fun and educational exhibit both kids and nostalgic adults can enjoy.

Three cheers for innovation and collaboration that helps us all learn. (And good riddance, stress-inducing buzzer.)
