Things that we never think (7 photos)

I want to remind you about the things that concern all of us, but for some reason we do not think about them.
Let's go ...



 
1. Your stomach is smarter than you think



Either the gastrointestinal tract has more neurons than many animals have in their brain! Their number and significance suggests that the stomach we have a second brain.

2. Are you covered with hair just like chimpanzees



On the human body hair has the same structure as in most other primates. We are different from chimpanzees only the thickness and length of hair, but not their number and location.

3. Your DNA has in its composition viruses



One of the biggest surprises us prepodnesёnnyh disclosure of the human genome, was the fact that our DNA consists partly of viruses. Viruses can not reproduce on their own - so some of them have found a clever way to "build" their DNA into the host cell to be copied later. If the virus inserts its DNA into sperm or egg cell, resulting offspring can carry viral DNA in each of its cells. Throughout human evolution, it happened so often that it is now at least 9% of our genome - a virus genes.

4. Your body is much younger than you



You change all the time. You breathe in, breathe out, eat, get rid of the discharge, and so on. N. The state of your body never repeats itself in the previous moment. And you are constantly updated: every second of the cell dies and is replaced by new ones. The farther you move away from the age of puberty, the less you are left with cells that belong to you since childhood. This leads to frequent philosophical debate: can you call yourself a if all the cells that were with you at birth, long ago replaced by new ones?

5. You are partially blind



Unfortunately, the structure of the human eye has one fault: the blind spot. In each of your eyes is a place devoid of the ability to perceive light, large enough to cause problems in people who have lost one eye. When fully complete eye blind spots remain unnoticed.

6. You can think of apart



Do you have an intuitive understanding of the amount, if the object is not more than 4. Not necessarily be able to count to understand "two" or "three" of the object you see before you. Even representatives of tribal feasts, in the language which, as we know, there is no concept bill also intuitively understand the amount.

7. Your body is strip



Just as in the coat in, for example, cats, you have to have a very clear skin lines and spots, but you do not see them. They are called Lines Blashko. It is believed that their presence is due to the migration of skin cells in the embryo they are templates, which can be seen as developing skin. The lines do not coincide with the pattern of muscle and lymphatic system, they form genetically determined. For diseases in which the lines become visible Blashko include varieties nevus, lichen and himerizim.
