Science fiction is filled with superheroes who have supernatural gifts. But the truth is that some common people also have special powers and often do not know.
It's about genetic benefits that a very small part of the population has.
These benefits arise due to genetic mutation, a natural process that changes our DNA.
Like some inherited genetic diseases, others have good luck and inherit the gene that gives them unusual abilities.
Here are five examples of some of the benefits you may have due to your genes.
1. Perfect underwater vision
Most of us we see everything blurred if we open our eyes when we are immersed in water.
This is due to a problem in the physics: Water tightness resembles that of the eye fluid and lack of light can not get into the eye well.
That is why people usually can only look good when we are in contact with the air.
But there is one exception: the mocking city, living in the Andaman Sea, a sector in the Indian Ocean between Burma and Thailand.
This tribe is known as "gypsies of the sea" because they spend most of the year in cabins on the water or in the boats and only land to ensure delivery.
If you have fainting genes, you can see crystal clear under water.
It is assumed that this genetic mutation occurred because Moken spends a lot of time underwater, collecting food from the seabed and spear fishing at the bottom of the ocean.
A scientific research published in the 2003 newspaper Current Biology revealed that the genetic mutation of the mok makes the eyes change shape under water.
This allows the light to break properly when it comes into your eyes and allows you to see clearly, even submerged over 20 meters below the water.
2. Tolerance to the cold
Another genetic advantage observed in some native people has to do with the ability to withstand low temperatures.
The human body has a normal temperature range that stretches from 36.5 and 37.5 ℃. That is why most people are better prepared to handle hot climate than cold climate.
A normal body can not withstand the extreme cold. However, there are some populations that have the capacity due to their particular genes.
Tribes such as Inuits, living in the Arctic, or Nenets, living in northern Russia, have adapted to freezing temperatures.
Their bodies respond differently to the cold because they are biologically different from the others.
For example, they do not shake off the cold, they have less sweat glands, their skin is much warmer than normal and their metabolism has much higher frequencies.
These skills are purely genetic: if you move to the middle of the north pole and live there for decades, you will not acquire the incredible ability of the people who carry these mutations.
3. Less sleep hours
A skill you can have without belonging to any tribe is to work well with less hours of sleep than usual.
Several studies have shown that most people need sleep between 7 and 9 hours in order to feel rested.
Sleeping less can cause problems with concentration and health, both physically and mentally.
A study conducted with twins in 2014 led the American Academy of Sleep Medicine to discover that there is a genetic mutation like that allows some people to need less sleep.
People with the mutated DEC2 gene have the ability to have a more intensive REM sleep, which makes their rest more effective.
With 6 hours of sleep or less, they feel completely rested and ready to meet the day.
However, experts explain that this mutation affects an extremely small proportion of people – less than 1% of those reporting that they sleep a bit.
That's why, if you sleep a little and you think you'll be good because you may have the genetic mutation, it's more likely that it's not so and you need more rest day.
4. Denser legs
This benefit seems to come out of a superhero comic. The character can be called "the man or the woman with the strong legs".
The majority of our skeletons they lose density and bone mass when we grow older. It is known as osteoporosis and can generate bone fractures and deformations.
But there are some people who have a mutation in a gene called SOST, which controls protein sclerosis, which regulates and controls the bone's growth.
A study conducted by researchers and researchers at Chiroscience in Bothell, Washington, found that those who have this mutation they do not lose bone mass as they grow older.
Their legs continue to accumulate density and mass over time, giving them the skeleton to a much younger person.
This mutation was found in some people of Afrikaners origin, as the population of Dutch origin living in South Africa is known.
Now researchers are looking for ways to replicate this mutation to allow other people They can reverse the aging of their skeletons.
5. Adaptation to heights
The Andean societies call it "soroche" and anyone who has suffered it will not forget it easily. It is the discomfort that feels at high heights due to lack of oxygen.
This altitude sickness or bad mountain It usually causes dizziness, low pressure, headache and respiratory diseases.
There are many tricks recommended to avoid it: move slowly, eat a little, do not do good effort, chew coca. Some people resort to medicines. But the truth is that even so many fall "apunados".
However, it is not a problem that affects the population living in the mountains.
Studies conducted Quechua of the Andes and Tibetans of the Himalayas They showed that they have genetic benefits that have enabled them to adapt to their environment.
Their torsos are larger and has greater lung capacity, enabling them to incorporate more oxygen with every inspiration.
And while most produce more red blood cells when the body gets a little acid, they produce less.
These properties are maintained even when these populations move to lower places, because they are part of their genes.
Perhaps this mutation does not officially make them "superheroes" but more than a tourist who struggles to climb into a mountain at the mire's pace and overcome by a place that goes up-sometimes carrying several bags-he probably believes they have super powers.
