General underwater view
Most of us have a & # 39; See everything if we are opening our underwater eyes. It is due to a physical activity: the density of the water is similar to those of the eye stream and the revival light can not go well. But there is one exception: members of the Moken people who live in the Andaman Sea, a part of the Indian Ocean between Burma and Thailand. It is believed to have risen. This genetic conversation as the Moken spends a lot of time underwater, Gathering food from seabed and fishing at the bottom of the sea. Research published in 2003 in the current Biology magazine published that genetic damage at moken lunches causes its eyes to change underwater shape, which allows light to revive correctly when it goes inside and allowing them to see clearly, even more than 20 meters deep.
This ability can be made without any need for any ethnic group in particular. A number of surveys have shown that most people need to be in a position; sleep between seven and nine hours. However, in 2014, American American American Academy researched a twin group and found that people with the DEC2 gene mutated the ability to do more difficult REM sleeping habits, which make the more are more effective; So, with six hours of sleep or less they are totally feeling; relaxed and ready to face the day. In any case, the experts clarify that this damage is done. affecting less than 1% of those who report that they are sleeping. So, find out your hopes: if you miss a bit and you think you're right because your genetic conversation may be, it's more likely you need more time .
When we get older, the skeleton will loss of density and size, because what the body does (usually inserts and replaces the nappy knit) is now working: and the newly created new vintage material is not enough to remove it. We all suffer from our bones due to & # 39; Their osteoporosis is just a bit: they have a variety of genera called SOST, which is responsible for controlling its & # 39; sclerostin protein, which regulates bone growth, and they still have a Longitudinal and long-term accumulation, which gives them the bones of a younger person. His conversation was found in some people of the awakening of Afrikaner (numbers of Dutch native people living in South Africa). Now, scientists have seen ways to represent this damage to allow others to be able to; fight against getting older than the skeleton.
Promotion to height
The Andean communities say that it is "really" and the people who have suffered it is easily forgotten: the uncomfortable problem with a high altitude feeling with a lack of oxygen , and there is usually disorder, low pressure, headache and respiratory disorder. That's why travelers are moved slowly, eating a bit, and enough "coca-te". But even if they are, many of them will fall "instead". At the same time, the guides that you will take to Inca Trail or to go with the walks to the Himalayan hills, on the waulk with boxes, do it as if anything … That's not a high illness & # 39; affecting the numbers that are; live in the mountain. Audits carried out among Andean residents and among the Tibetan of the Himalayas show that they have genetic benefits that allow them to change their environment: there is a larger torso and a larger lung capacity, which allows them to increase the amount of oxygen to embraced with every spirit. And although most people have a make more red blood cells when they get a lot of oxygen, they'll do less. These features are even maintained when these numbers move to lower areas, because they are part of their genera.
Tolerance to the cold
The range of normal temperatures of people is between 36.5 ° and 37.5 °; That's why we are better to deal with the heat. But the Inuits, who live in the Arctic, or Nenets, from the northern part of Russia, have a special genetic difference, received from Denisova man (described in 2010 as a species of new people). This gene helps to & # 39; heat-making by reinforcing a type of fat, and let them stay in very cold habitats.
