5 genetic advantages that most people do not have



[ad_1]


Science fiction is replete with heroes who have supernatural gifts. But the truth is that some ordinary people also have special forces and often do not know.

It is about the genetic benefits that a very small part of the population has.

These benefits derive from genetic mutation, a natural process that changes our DNA.

Just like some hereditary hereditary diseases, others have more luck Inherit genes that give them extraordinary abilities.

  • Miguel Pitta: "If you do not have the right genes you will never become Mozart"
  • 5 aspects in which genetics affects your daily life, and you probably do not know

Here we give you five examples of some of the benefits you can get thanks for your genes.

1. Perfect underwater vision

Most of us We see everything blurred If we opened our eyes when we were in the water.

The reason for this is a problem in physics: the water density is similar to that of the eye fluid, and the returning light can not enter the eye well.

This is why humans can usually only see when we are in contact with the air.

If you open your eyes underwater, you'll see everything blurred. Unless you have a moken blood. stock

But there is an exception: The city of Mocken, Which lives in the Andaman Sea, a branch of the Indian Ocean between Burma and Thailand.

This tribe is known as the "gypsy sea" because they spend most of the year living in huts on water or in boats, and only go to land to stock on supplies.

  • In the photographs: the moken, the gypsies of the sea

If you have landscaped gardens you can see crystal clear underwater.

It is believed that this genetic mutation arose because it was spent spending a lot of time underwater, collecting food from the sea and fishing spear at the bottom of the sea.

A scientific study published in 2003 in the journal Current Biology revealed that a genetic mutation of moken makes their eyes Transform underwater.

This allows the light to reflect properly while entering your eyes and allows you to see clearly, even submerged more than 20 meters underwater.

2. Tolerance to the cold

Another genetic advantage observed in some indigenous peoples is related to the ability to withstand low temperatures.

The human body has a normal range of temperature ranging from 36.5 and 37.5.. That is why most people are better prepared to deal with a warmer climate than a cold climate.

  • Why does extreme cold and heat cause us so much pain?
  • What is the coldest place on Earth and why do we know now that the temperature is even lower than previously thought?

Normal body Can not withstand the extreme cold. But there are some populations that have this ability, thanks to their special genes.

Tribes like the Inuit, which inhabit the North Pole, or Nantes, who live in northern Russia, have adapted to freezing temperatures.

Their bodies react differently to the cold That are in a biologically modified form differently from the rest.

For example, they do not tremble from the cold, they have less sweat glands, their skin is much warmer than usual and the metabolism has much higher.

These skills are only genetic: if you move to the middle of the North Pole and live there for decades, you will not be able to acquire the amazing abilities of the people who carry these mutations.

3. Less hours of sleep

One skill you can, without belonging to any tribe, is to work well with fewer hours of sleep than usual.

Several studies have shown that most people need sleep Between 7 and 9 hours To feel comfortable.

Experts recommend 8 hours of sleep … unless you have this genetic mutation. ISTOCK

Less sleep can cause problems of concentration and health, both physically and mentally.

However, a study conducted with twins in 2014 led the American Academy of Sleep Medicine to discover that there is a genetic mutation Allows some people to sleep less.

People with the DEC2 mutant gene have the ability to have more intense REM sleep, which makes Sharm more effective.

With 6 hours of sleep or less they feel completely rested And ready to deal with the day.

However, experts make it clear that this mutation affects a very small percentage of people – less than 1% of those reported for a small sleep.

So, if you sleep a little and you think you will be fine because you may have the genetic mutation, it is more likely that it is not so and you need more hours of rest.

4. Closer bones

This advantage seems to come out of a comics hero. The figure can be called "man or woman with strong bones".

Most of our skeletons They lose bone density as we age. It is known as osteoporosis and can create bone fractures and deformations.

We all suffer from the wear and tear of our bones because of osteoporosis … except for them. ISTOCK

But there are some people who have a mutation in a gene called SOST, which controls the protein sclerostin, which regulates and controls the growth of the bones.

A study conducted by research and development scientists at Chiroscience in Bothell, Washington, found that those who have the mutation They do not lose bone mass As they get older.

Their bones continue to accumulate density and mass as time passes, giving them the skeleton of a much younger person.

This mutation was found in several people of African origin, as Dutch-born populations living in South Africa are known.

Now scientists 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 communities call it "Sorok" and anyone who suffered it will not forget it easily. It is the discomfort that is felt at high altitude by the lack of oxygen.

It Altitude sickness or bad mountain It usually causes dizziness, low pressure, headaches and breathing disorders.

There are many tricks you may want to avoid: move slowly, eat little, do not make great efforts, chew coke. Medicines should be applied. But the truth is that even so many fall "apunados".

You suffer when they carry your little backpack and a full-luggage Sarapa passes you around like … nothing … we explain how they do it. GETTY

However, this is not a problem that affects the living populations in the mountains.

Studies conducted Kochi of the Andes and Tibetans of the HimalayasThey showed that they had genetic advantages that enabled them to adapt to their surroundings.

Their tendons are bigger There is a greater lung capacity, Which allows them to combine more oxygen with each inspiration.

And while most people produce more red blood cells when their body gets smaller oxygen, they produce less.

These properties are saved Even when these populations move to lower places, Since they are part of their genes.

Perhaps this mutation does not make them officially "heroes" but more than a tourist who is struggling to climb the mountain at the rate of an ant and is taken over by a place running up – sometimes carrying several bags – no doubt he believes they have powers.
