Great progress has been made in science In recent years, hundreds of discoveries have revealed it there are genetic diseases and that, as there are diseases, there are also genetic advantages.
There are very few lucky people all over the world who manage to develop some of them Special abilities, the genetic advantages arise due to a mutation, ie a process that changes it DNA
One of them features especial offers the most common one is cold tolerance, as a normal body can not resist extreme cold, the body of people has a range of temperatures between 36.5 and 37.5 ° C.
However, there are some populations that your body has this ability for especially genes grow, breeds such as the Inuits, residing Arctic, or the Nenet, living in the north Russia, have been adapted to freezing temperatures.
Genetic advantages are due to its mutations DNA and as a result the body of members of these populations have fewer sweat glands, The skin is much warmer than normal and the metabolism has higher rates.
Another of the most common advantages that some manage to develop through its change DNA is to live with fewer hours of sleep, people with the gene DEC2 Mutants have the ability to have a dream REM more intense, making the rest more short and effective.
Other than the genetic advantages It's hard to find, but it's not impossible to do it. it's about aquatic vision perfect for example the city Moken, living in the sea Andaman can see clearly when they sink under the water; this ability makes his eyes change shape under the water to make it the light is refracted correctly.
Higher density in bones, As the body sinks, the skeleton loses strength and bone mass, but there is a mutation in the gene SOST what happens completely what on the contrary, the bones accumulate the power and the mass with the passage of time. this mutation exists in some individuals of origin afrikaner (populations of Dutch origin living in South Africa).
