Certain rare body features are present in few people across the globe.
“We have similarities with everything else in nature; it would be astonishing if we didn’t.
But we’ve got to look at the differences.”
Humans don’t just differ from other species, though.
We’re also different from one another.
Despite a worldwide population of over 7 billion people,each person has an entirely unique face.
Bodies, too, are incredibly diverse.
This means that we areallunique.
Yet and still, there are some people who areespeciallyextraordinary ormoreunique on a biological level.
From extra body parts to heightened senses, these are some of the rarest features very few people have.
However, there’s a chance that some people actually have 25 ribs.
It’s possible you have one and don’t even know it.
It may sound concerning, but cervical ribs are usually no big deal.

Three types of this condition are known to exist: complete, central, and partial.
A person with complete heterochromia has two different coloredeyes, like one brown eye and one blue eye.
Two different colors in the same iris is considered central heterochromia.
Lastly, partial heterochromia means just a part of the iris is a different color from the rest.
Heterochromia whether acquired or genetic is extremely rare.
In the United States, fewer than 200,000 people have the condition.
Not many have the rare body feature red hair
Natural red hairis rarer than you’d think.
As Harvey explained, red hair is recessive.
“It is trumped by every other card in the pack.”
to get to have a child with this hair color,bothparents need to possess the gene.
And blue eyes are already pretty rare in and of themselves.
Only an estimated8to17 percentof the world’s population has blue eyes.
An even rarer eye color, though, is gray.
World Atlasreported that less than one percent of the human population is estimated to havegray eyes.
According to theAustralian Academy of Science, Rhnull blood that entirely lacks Rh antigens is much rarer.

However, preauricular pits can be prone to cysts and infections.
In such cases, the pit may be removed to prevent recurring problems.

What causes the rare body feature of a double row of eyelashes?
Withmagnetic false lashes, we can all have lush, layered eyelashes.
People with distichiasis, though, already have this.
It results froma genetic mutation of the FOXC2 gene.Elizabeth Taylorhad this mutation to thank for her voluminous lashes.
Chan School of Public Health’sThe Nutrition Sourcerevealed.
These super-tasters have more visible taste papillae tiny dots on the tongue than do non-tasters.
Because super-tasters also have more pain receptors than non-tasters, they generally do not likespicy food.
They’re also less likely to smoke and don’t typically like alcohol.
Unfortunately, though, they also don’t consume as many vegetables.
This is because veggies tend to have a bitter taste.
Considering super-tasters also don’tlovesweet and fatty foods, these things may very well be linked.
Outie belly buttons are rare body features
Chances are you have an innie belly button.
Of the participants,only four percentreported having an outie belly button, a rare body feature.
Most of the people opting for cosmetic belly button revision surgeries, orumbilicoplasties, go from outies to innies.
He continued, saying, “They have extraordinarily dense bones and there is no history of fractures.
These people have about the strongest bones on the entire planet.”
