Humans have been puzzled by things like the depths of the ocean and outer space. But one equally mysterious object has been standing right in front of you when you look in the mirror. It’s a human body.
And one TikTok creator named Knowledgesaurus has been stripping away the mystery surrounding it in a series of “How Rare Is Your Body?” videos. From explaining what percentage of people have features like cracked tongue, angled palm crease, or an extra rib, to counting how many people have the ability to write with both their right and left hands, or can make a clover out of their tongue.
The informative and fun videos gained Knowledgesaurus immediate popularity with millions of views and 1.3M followers, so let’s see some of the most interesting body facts that will pump your biology knowledge muscle so you can show it off in the next trivia session.

25% of people sneeze when they're exposed to direct sunlight. It's called the photic sneeze reflex.
30% of people can flare their nostrils on command. However that muscle has very little use and is usually weak, so a lot of people can't do it on command.
Only 12% of people have tetrachromacy - the ability to see a lot more colors than the majority of people. They can see about 10 times as many shades and colors as someone with normal vision.
Aight dangit, now I wanna know what colors I'm missing out on...Or am I not missing any at all....hmmmmm.
With 1.4 million followers and 38.5 million likes on TikTok, Knowledgesaurus is the internet’s beloved creator sharing everything interesting—facts, smart observations, and common myths—in lighthearted and fun videos. Bored Panda reached out to Knowledgesaurus to find out more about his personality and how his love for fun facts and dinosaurs won the hearts of the internet.
2% of people naturally have red hair. In order to have a child with this hair color, both parents need to possess the gene, and while redheads make up a tiny part of the population, one study found that 30% of ads have people with red hair in them.
My maternal grandma and grandpa were redheads, my mom and sister are redheads, my husband's dad had read hair, my son is a red head. Out of 23 niblings in both families, my son is the only redhead
Less than 1% of people can hear colors or see sounds (synesthesia).
9% of people can taste the soap taste in cilantro. Cilantro contains the chemical that is also a byproduct of soapmaking.
“I’m 25 years old and have been an entrepreneur since the age of 19. I found success with that early on and ended up dropping out of college. I made good money, but wasn’t happy.” At that point, the TikTok creator took a risk and decided to “stop all that and start something more fun that I’m interested in and that’s how Knowledgesaurus started. I started this account 1/1/2021 with the goal of growing it and making it my full-time job and within 110 days, I was able to reach 1 million followers, which I’m so thankful for!”
5% of people have amber eyes - golden or coppery with flakes of gold, green or brown. Amber eyes are very common in dogs, bird and fish.
Less than 1% of people have this small little hole right on their ear. Some evolutionary biologists claim this used to be a gill on humans.
24% of people can raise one eyebrow, however you can learn to do this as well.
When asked how he came up with the idea for the "How Rare Are You?" series, Knowledgesaurus said it started after making a bunch of videos and seeing what people enjoyed watching. “I realized that people love to know information about themselves and love statistics. So that’s how the series began.”
“I always loved knowing random useless information to surprise people with,” the content creator said and added: “I think it all started when I was younger. If someone was talking about something I didn’t know much about, I would go and look up stuff about it and find interesting information about that topic so I could have a better conversation next time.”
10% of people have something called Morton's toe. It's when your big toe is shorter than the one next to it. The Statue of Liberty actually has a Morton's toe as well.
Only 33% of people can whistle. Almost everyone has the ability to whistle, it just takes the right techniques.
Well, if you can't whistle it's because you didn't eat the crusts of your bread. Or so my mother claimed.
Only 1% of people are ambidextrous - they have no preference for the use of right or left hand.
1% of people need less sleep than the rest of us. These people have Sleeper Syndrome which allows them to go through a sleep cycle faster than an average person.
35% of people have no wisdom teeth. Wisdom teeth used to serve a purpose but now they no longer do, which is why we take them out so they don't get infected while they're pushing through your gums. If you don't have wisdom teeth, I'm jealous of you.
35%?? Everyone I know has or had wisdom teeth. Does this occur in certain populations?
83.7% of people can roll their tongue, but only 14.7% of people can make a clover out of their tongue.
4% of people have Raynaud's syndrome. This is when a part of your body, usually your fingers or toes, starts to turn white when exposed to low temperatures. It's your body's overreaction to cold or distress.
I have this! It's incredibly painful & feels like the worst kind of pins & needles imaginable.
Only 10% of people have Darwin's tubercle - the little bump on the outside of your ear. It's believed that people who have this are better at sensing voice tonality.
Less than 1% of people in the US have AB-Negative blood. There's also something called Golden blood, which only about 40 people in the world have, and it's completely different than any other blood.
16% of people can make a roaring noise in their head using their jaw. They're able to do this because they can control a small muscle in their jaw that deafens chewing, but when it is flexed it makes a roaring noise.
I can do this too, but I thought this was something everyone experiences
Less than 1% of people have unbreakable bones. This is caused by a mutation in one of the genes that causes the bones to be up to 8 times denser.
35% of people can gleek. Only 1% of people can do it on command. Gleeking is when you're spitting saliva from under your tongue and it squirts out.
Less than 1% of people are born with a white patch of hair. It is called poliosis, which is caused by the lack of pigment called melanin in the hair follicles.
Two of my maid’s children have this. Brown and white hair. I love their hair.
Only 5% of people have arched fingerprints. Most people have looped and whorled fingerprints.
Less than 1% of people have their heart on the right side of their body. Surprisingly, this doesn't normally come with any negative consequences.
Only 25% of people have dimples. You can have either two, or just one. Dimples are also hereditary, so if either of your parents has a dimple, it's more likely you'll have one as well.
20% of people have a gap between their two front teeth. What normally causes this is a discrepancy between the jaw size and the teeth. A lot of celebrities have this and don't correct it because they think it makes them unique.
Some people believe this is an indication that you will become rich. I have yet to see anyone who has.
Only 2% of people naturally have blonde hair. If you narrow it down just to white people in the United States, that percentage goes up to 5%.
I think it depends on what you classify as blonde. Is it truly white hair or just lighter (like dark blonde)?
Only 10% of people have birthmarks. They're usually oval in shape and come in a coffee type color.
I used to have a big oval birthmark, on my lower back. But it faded as I got older and eventually disappeared altogether.
My nephew has a big birthmark on his tummy and it keeps getting bigger and darker as he grows, no hair though.

Birthmarks appear differently on different skin tones. You're leaving most skin tones on earth out, if you limit birthmarks to being "coffee colored."
true. some can be black, red, or pale brown. my mother is brown and has the entire spectrum of birthmarks.

i have a large strawberry red birthmark on my scalp but since i have so much hair it's difficult to see it
In my country they say that birthmarks are created during pregnancy when the mum is craving for something and doesn't eat it!! Probably it was a way to make sure their cravings would be fulfilled so the baby is not born with tons of birthmarks!!😅😅😅😅

There are lots of different kinds of birth marks though. I have a pale reddish one on the back of my neck called a stork bite.
I've got one on my ring finger. My mother and father thought it was dirt when I was a baby and tried to clean it off lol
I have a fish shaped one that only looks like a fish when I look at it, not other people. Some people have said it has to do with me being a Pisces.
My sister has a birthmark like this, mine is truly white, like the skin doesn't have any pigment in it on that spot
I am covered in birth marks. My worst one is on the back of my neck...
Mine is a bit paler than coffee, but it’s shaped like a heart and is on my forearm :D
I think I have a birthmark in the back of my thigh. It’s large, but it’s so light you can barely notice.
Mine used to be on the back of one of my thighs, it looked like I got burned 😂
I have one that I've been warned to keep an eye on it for changes like darkening, thickening, and (especially) bleeding. https://birthmark.org/birthmark/port-wine-stain/
My daughter has a perfect pink strawberry birthmark on her right butt cheek. (She's 32 and would be ansolutely mortified if she knew I made that public). Her name is - hahahaha, I'm not THAT mean!
I was born with a red mark that started on my forehead, between my eyes, went up over my head and straight down my entire back. Mostly faded now, the nape of my neck and small of my back still have a lot of redness. It freaks out hairdressers who think they’ve burned me,
I have an oval on the right between my chest and my stomach, and a splatter on my left leg. I like to think they indicate how I died in a past life.
i have one that looks like an triangle on my knee that is a reddish pink color. is that normal?
Only 10%?!?! I always thought that EVERYBODY had a birthmark! Everyone in my family has one! :O
Yep, mine is oval but more like the color coffee looks like with cream. Maybe it just looks that way because I have dark(ish) skin.
I used to have one but it's gone. My cousin has a birthmark that's spreading, it covers half of his nose and is inching up his face, he wants to get it removed but I think it makes him adorable and it helps me recognize him
I have three unusual ones, one shaped like a symmetrical heart that we draw all over when in love❤️, a tiny patch of green on my arm, present since birth and a dull creamish colour tree top shape just below my shoulder 😀
I have one on my wrist. It's reddish though. It's not uncommon for people to ask if I hurt it.
I do. Right on my freaking face. Just dark enough to be mistaken for dirt. I hate it.
I have a huge one on my hip and my cousins has an identical one in the same place. My son has one similar higher up on his back
That’s crazy! I thought everyone had one, mine is on my right leg
I have one on my ankle. It just looks like a brown blob.
My nan , her , and myself all have the same birthmark on our shoulder
I've got 2 on my right knee, both about the size and shape of a cornflake.
I have one, was always embarrassed as a kid... it is on my side, its small but I used to wear shirt to swim because of it.
i have a bunch of birthmarks, but they're lighter than my natural tone. i also have some darker coffee colorred ones.
My birthmark is on my left cheek and it looks like a scar, Doctor said I likely scratched myself in the womb, I like to tell people I had a conjoined twin and we were attached at the face
Mine is a strawberry birthmark on my complete lower back right above my hip line. Completely horizontal, looks like it could be hives. None of my 3 younger siblings has anything like it.
My sister has a light patch on her face, idk if it's a birthmark or what, and I have a huge slightly darker patch on my stomach that wraps around the left side of my abdomen
I had a blue birthmark on my eyelid, it went away tho, and I also have another blue one on my scalp
I have one in my leg. Ok, birthmark, no wisdom teeth and gap in the front teeth, what are the odds of me?
Mine is right down the middle of my nose, but it's faded with old age.
I thought everyone had a birthmark? Mine is on my inner thigh and looks somewhat like a hammer😅
My husband has a big one on his chest. It also has hair growing from it
Mine is purple and exactly the shape of the South Island of New Zealand. On my stomach and 8 inches long. I hate it. Drs always ask if they can take a photo.
I have a large brown birthmark. (Not on my face) Most people who teased me about it were family members. No one really pays attention to it now. I put 60 spf sunscreen on it when I'm outside and now it is barely noticeable.
It's said that your birthmark is where you suffered an injury that killed you in your passed life, I got stabbed between the ribs just below my heart, I wonder what I was doing 🤔
70% of people bend their head to the right when kissing. Your brain is the cause for this. The left side of our face shows more emotion so we want to give our partner the more emotive side and we tilt our head to the right.
1% of people have a double row of eyelashes. While this might look like something a lot of you are jealous of, it actually can cause a lot of problems.
Less than 1% of people have pointy or elf-like ears. It's an abnormality called Stahl's ear, it's usually corrected early in life.
Why does it need correcting? Isn't it just a cosmetic difference? Shouldn't it be up to the child to keep it or change it once they're old enough to make the decision, as long as it isn't impacting their hearing?
Only 35% of people have 20/20 vision. 2/3 people cannot see perfectly.
25% of people have perfect teeth and never need braces or any orthodontics. 45% of children need braces, but 75% need orthodontic care.
Need or want? My teeth aren't perfect and if I was an actor or something, I would've 'needed' braces, but health-wise I don't. So do they mean 75% will have health problems if they don't get work done, or just that it looks ugly?
14% of people don't have this muscle - Palmaris Longus. This muscle was developed when our ancestors were big tree climbers. If you want to see if you still have it, pull back your palm on a flat surface, touch your pinky and thumb together and slightly lift them and you should see that ligament pop out.
6% of people can vibrate and rapidly shake their eyeballs back and forth.
10% of people can touch their nose with their tongues. In medicine, this is called the Gorlin sign.
20% of people are double jointed. This is thought to be genetic and due to a variation in collagen in your connective tissues.
4% of people are colorblind. Color blindness occurs in 8% of men and 0.5% of women.
Less than 1% of people can give themselves goosebumps on command. The majority of people get them when they're cold or listening to music, but some can give themselves goosebumps whenever they want to.
yup i just have to imgine biting into a popsicle. lol i liteally got goosebumps writing this.
Only 12% of people dream in black and white.
Only 1% of the population can lick their elbow. The people that can do this usually have either a long tongue or a short forearm, or both.
Hmmmm...I wonder...:: unsuccessfully trying to lick my elbow...Wife walks in and witnesses me trying::: Wife- What the ever lovin h3ll are you doing? Me as embarrassment and awkwardness set in:: Ummm... nothing hon...nothin at all...
10% of people are left handed. Left handed people tend to live shorter lives.
8.4% of people have a counterclockwise hair whorl on their head, while the majority has a clockwise one.
8% of people still have chimp-like feet, that are specifically adapted to climbing trees. This is characterized by a mid-foot arch. If you want to check if you have this, see if you can bend the ball of your foot as well as the region half-way between your heel and the ball of your foot.
I had a hard time understanding this, because that picture is not showing the mentioned bend at all. This is what it looks like: https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcRv7izzuQZ8x4BdXJ5PzLGWd-Ogt4KLZ4xgMQ&usqp=CAU
Only 4% of people have an outie belly button. Believe it or not, doctors can't choose if you'll have an innie or an outie belly button, things like the belly button itself and the fat beneath it determine what it will look like.
Less than 1% of people have an extra rib. Most people are born with 24, but some have 25 ribs. The 25th is called a cervical rib.
25% of people have a Hitchhiker's thumb - when the upper part of the thumb can bend 90 degrees backwards. It's caused by a certain gene.
About 20% of people have a pupil that is bigger than the other. This is called anisocoria, it can be a very small, or a very big difference.
Note: this post originally had 60 images. It’s been shortened to the top 50 images based on user votes.
Fascinating post. Luckily I read it early in the morning so no one saw me trying to lick my elbow, wiggle my ears, flare my nostrils, etc.
Something else that is also rare: having both red hair and blue eyes, and it’s actually the rarest combo on earth. This is because red hair and blue eyes alone are both rare, and both parents have to carry the gene for the child to have red hair and blue eyes. I actually have red hair and blue eyes. Both my sisters have red-ish hair, but their eyes are not blue and their hair isn’t nearly as red as mine.
I have grey eyes and reddish hair. I hardly see anyone else with grey eyes.

This was fun and I had quite a few of these. Going to celebrate my weirdness!
This was so cool! Today I learned that I have twelve of these, including a few that only one percent have.
I found out recently that my blue/gold center heterochromia (blue eyes with a gold ring) is exceedingly rare. My family and I always called my eye colour “Blue Hazel.”
Does anyone know anything about sharper canine teeth? Mine are much pointier than anyone in my family.
I don't know if it means anything. My dad had them too. When he was little my nephew wondered if I was a vampire. Never thought, I could have dressed up as a vampire on Halloween and not needed the fake teeth.

I have at least 16 of these, I wonder if some are likely to be associated with each other? Morton's toe, hyper flexible, extra rib, dimples, eye brows, seeing extra colours, ear wiggling, touch tongue to nose, nostril flare, preauricular sinus, whistle, gap tooth, never needed braces, gleeking, goosebumps and snoring. I only had 3 wisdom teeth, which is quite rare as well, and a form of Synaesthesia where I experience pain as smells.
So, who else scored themselves? 11 out of 50 weird things. unfortunately, mostly useless ones. lucky in some areas like colour acuity and 20/20 vision[failing with age though].
As a people of 1, I was included in 0% of the questions, some of which I would not have answered
I have an extra muscle in my elbow called anconeus epitrochlearis. It causes pressure on my ulnar nerve sending some of my fingers numb sometimes and cause me to have a weak grip and I only have it on my left elbow.
10% of the population has 6 lumbar vertebrae. I am one if them and only found out when I needed a spinal fusion.
My stupid human trick is I can move my uvula at will and make a sound :)
My genetics prof was discussing different inherited traits. He mentioned that lobed or unlobed ears was one of them. I sat perfectly still with my one lobed ear and one ear not, trying not to be noticed.
If your not one of those from any country ( my fault but whales matter!!!) I hope we can rise and leave the ocean alone alittle. Just alittle.
Don't care if I'm the bitch. How on earth could I be that???? Yes yum, no whale obviously.
Load More Replies... I'm so so over it. If I get cancer n shark fin could cure me! I will say no. Unlike U many shark fin soup dickheads. My grandfather survived old n no treatment. Not racist again but f**k you whale killers n Asians who would probably eat humans.
Please stop hurting whales, sharks n dolphins. I can't handle not being able to stop you.
I'm done. You next generation are too much!! Why can I not say one single thing without it being blown out of proportion??? If a Asian asked me why am I being mean against whales being murdered, I will say " "And how's your sushi bitch'. Or yes you don't understand me & I don't understand you. No worries.🙂🙂🙂
I don't judge, but your making it f*****g harder that it should be!!!!

Does the chimp feet thing count for picking stuff up with your toes, or is that something most people do on a daily basis? I do it often myself when I see something on the floor but don't to bend over.
I used to be able to peel a banana with my toes. A broken foot put an end to that charming party trick..

Wow I'm even more of an odd-duck than I thought. I can do/have a lot of these. And some not on the list, like central heterochromia, around my pupil is an amber(ish) brown, and around that is green.
Went back and counted off on my fingers, 11. And might even be 12,can't see my fingers in the darkness of my room.

I can wiggle my ears on command, and so can my Dad. I've never met anyone else that could. I'm curious what % of the population can do that... I also have red hair, blue eyes, and a bunch of the other "rare" traits listed here, so let's just go ahead and call me a freak of nature lmao
Cool! Like an activity to find out if you're special! And have hidden talents
What fun! I'm blonde (but boring old green eyes), can flare my nose, taste the soap in cilantro, have arch fingerprints, raise both eyebrows individually, have shorter big toe, sunlight makes me sneeze, have Reynaud's, only need 4 hours sleep, have hitchhiker's thumb (though never used it!), have Darwin's tubercle, can wiggle both ears, have palmaris longus, and perfect pitch.
Green eyes are incredibly rare, believe it or nto. Only 2% of the entire worlds population has green eyes, and iirc, they are the rarest eye colour aside from "mutations" that may cause different eye colours like a reddish or violet eye (albinism for example) (I also use the term mutation lightly, as funnily enough, the genes that cause a person to have green eyes initially was a mutation, same as with blue eyes, and this can be tracked down to certain specific ancestors, meaning people with green or blue eyes may be very, very, very, veryx10000 distantly related to each other xP) That means that freaking amber eyes are actually more common than green eyes. o.o So not, "boring old green eyes"!
