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.

Person Invites You To Learn 'How Rare Is Your Body?' In His Viral Series 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.

You aren't missing much. Tetrachromacy in humans is nothing like tetrachromacy in birds. The wavelengths of light we see as red, green and yellow are really quite close together. The ability to differentiate between red and green evolved fairly recently in primates (see my other comment), so the genes are still similar and the proteins they encode detect very similar wavelengths. And because they are still evolving, people have different versions of the genes and detect slightly different wavelengths as red and green. The genes are on the X chromosome so women can get two versions, and if the versions are sufficiently different they can detect extra shades. But because the genes are still very similar even in that case, it's really more accurate to say that they see "extra shades" because it's still a very long way from the tetrachromacy of birds.

My dad was a house painter for over fifty years. I don't think he can see extra colors, but his eye for tones is amazing. He can look at two shades of off-white that look the same and tell you that one has a little more yellow, for example. I love the weird skills that people develop after years doing a job.

Previous studies have shown that women are much better at picking out slight differences in color than men... and IMHO that's because women have had to pick out lipsticks! Lots of women can look at 500 reddish colors all displayed together, and tell you how they differ. So really, what I mean to say is that I agree with you, I think that kind of color analysis is learned.

I know tetrachromacy exists but the above graphic is, I believe, simplistic and misrepresents what tetrachromacy actually is. This graphic is more of an illustration of how a person who knows the name of a shade sees the spectrum vs. someone who doesn't know the name of a shade. Outside of those who are color blind I'd be willing to bet that all seeing this graphic can see all the colors represented. Tetrachromacy allows a person to see colors outside the normal spectrum and there is no way to represent this because, unless you're tetrachromatic you can't see these colors.

No the graph is unrelated, it belongs with the myth that women have more names for colours and distinguish more (by name). The actual graph is from (the comic) Doghouse Diaries. XKCD did fun non-scientific research on that a few years ago, worth a read and a few laughs, at https://blog.xkcd.com/2010/05/03/color-survey-results/

We have three types of proteins for color perception. Each is encoded by a single gene. They are related to each other- i.e. the gene for the color perception protein got duplicated on the DNA, and mutated to detect a different color. A lot of animals (birds, many fish) have true tetrachromacy - they have four proteins which evolved to detect colors that are perfectly spaced out on the range of visible light. Mammals lost some color vision genes and have only two of the proteins (short wavelength blue, long wavelength = red AND green together). Primates can see three colors - the long wavelength gene duplicated, mutated, and so primates can differentiate between green and red. These genes are not done evolving, so people disagree about shades of green, red and yellow because their proteins detect slightly different wavelengths. Women can can get two versions of the genes, and if these versions are different enough, they are technically tetrachromats - but nowhere close to birds!

There's a game I play called "I Love Hue" and you have to organise the squares so it completes a full transition from one colour to another and I love it! Some of the differences between colours are only evident when they are beside another.

You can show people colors that are similar but still different, and test how well they can correctly detect the difference. Also, there's this test where you get a green flashlight and a red flashlight and are asked to replicate a certain shade of yellow by mixing the lights and adjusting the intensity. Science background: We have three receptors for seeing color which are activated when hit with a certain color light (blue, red, or green). They have an "ideal" light wavelength where they are activated the most - but they are also activated by neighboring wavelengths of light, just less so. The mix of how much the detectors are activated is how we see the color range: green = green receptor maxed out, red much less, red = red receptor maxed out, green much less, yellow = both receptors activated about the same. (to be continued)

I have read that women can usually see more colours than men, and more men are colourblind that women, because hunting carnivores usually see in black & white, while herbivores see more colors. Men were traditionally hunters, while women were gatherers and needed to distinguish subtle colors of vegetation. We have 2 mushrooms in our yard, one is red-orange and edible, the other is slightly redder and poisonous, so that is a big difference!

That is... incorrect. Entirely. Most mammals see only 2 colors - both herbivores and carnivores. Most birds see 4 colors - again, both herbivores and carnivores. The ancestors of mammals likely could see at least 3 colors. The theory is that during the time of the dinosaurs most of them were nocturnal and/or burrowing and lost some color perception during that period. Primates are the only mammals that can see 3 colors - and at least in this case, the reason is likely that it was a huge advantage for a species eating a lot of fruit. But it takes ages for this new color vision to truly settle (we are still not done!), so diets can change several times before that. Also, the labor division between men and women that long ago can't actually be proven. Quite likely everyone was mostly gathering and hunting was less frequent. The genes for seeing red and green are on the X chromosome, so women have a spare if one is broken and men don't. THAT is the reason women have better color vision.

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?

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?

I wish they'd stop calling it double jointed. There are no double joints. Like it says, it's just a variation in connective tissue and joint flexibility.
