Unknown mutation of the body
• The unknown mutation of the body
Deep inside, we all the X-Men.
In your body there is a mutation, which you did not know, simply because it is a common feature of modern man, or because they have not seen in this acquired feature.
Although in some ways this applies to everything in us. Trace the evolution of man, and you will see that any property that we have appeared due to the mutation.
But now we talk about the latest developments in human genes.
So, here are some features that were not our ancestors.
The ability to digest milk
About 10 000 years ago when Europeans domesticated cows in MSM6 gene mutation has allowed people to produce the enzyme lactase. This allowed them to drink cow's milk.
In other agricultural societies, such as India, the ability to digest milk was developed in parallel at the same time.
We take for granted that most people can drink milk, but it is not the ability that we have had from the beginning.
Useless wisdom tooth
wisdom teeth - a nightmare, especially when removing the need for their operation. And, for the most part, they are useless for modern people.
But they needed were human ancestors that had large molars for chewing hard plant, make up a large part of their diet. Modern people eat specially bred, soft varieties of vegetables, so our jaw are narrower, and the third row of molars begin to disappear in our species as unnecessary. About 40 percent of Asians, 45 percent of the Inuit, 25 per cent of Europeans and 11 percent of blacks did not have any of the third molar.
So if you have not, do not think that you have lost something.
It was found that this mutation began about 350,000 years ago that found the fossils from China due to the absence of the third molars.
One of the best known mutations.
Only four or five percent of people have this mutation, and the people in northern Europe are more likely to get it. This is probably due to the amplification of the gene due to the positive selection or due to lack of negative selection in cold climates.
Some are concerned that this regressive gene may disappear because of globalization, the increasing diversity of genetic variation or due to changes in climatic conditions.
The blue eyes
In all, eight percent of the world's blue eyes, and he recently appeared on the standards of evolution - from 6 000 to 10 000 years ago. Previously, all people's eyes were brown, and blue-eyed first man in history, appears to have lived in Europe.
Change eye color was due to a gene mutation, which is now called OSA2. This mutation affected the amount of pigment produced by the human body, allowing to create different shades of brown, and eventually led to the emergence of other colors.
