Major progress has been made at science In recent years, hundreds of discoveries have revealed this there is a genetic disease and that is the same as there is a disease there too genetic advantage.
Very little lucky people all over the world who successfully developed several special ability, genetic advantage arises thanks to a mutation, that is to say to a process that changes DNA
One of them characteristics especial the most common are cold tolerance, because the normal body can't hold back very cold, the human body has a temperature range between 36.5 and 37.5 ℃.
However, there are certain populations that your body has thanks to that capacity special gene developed, tribes like the Inuits, who lives it Arctic, or Nenet, who lives in the north Russia, have adapted to freezing temperature.
Genetic benefits are thanks to mutations from DNA and as a result the bodies of the members of this population they have fewer sweat glands, The skin is much warmer than usual and the metabolism has a higher level.
Another most common advantage that some people have developed through change DNA is living with fewer hours of sleep, people with genes DEC2 mutate has the ability to dream BRAKE more intense, which makes more rest short and effective.
Others from genetic advantage They are quite difficult to find, but it is not impossible to do it; this is about aquatic vision perfect for example city Moken, who live in the ocean Andaman can see clearly when submerged under water; this ability causes the eyes to change shape under water so they make light refraction correctly.
Greater density in bone, When the body ages, bones lose strength and bone mass, however there is a mutation in the gene SOST What happened fully What? on the contrary, bones gather strength and mass with the passage of time; this mutation is in some people who come from afferent (Dutch population living in South Africa).
