TOP 10: UNSOLVED
MYSTERIES OF
HUMAN
Surprisingly, modern science still some puzzling
features of our physiology and psychology. British popular science magazine New
Scientist has made a rating of the inexplicable.
1. ABILITY TO BLUSH OF SHAME
Scientists believe one of the greatest gaps in the
theory of evolution no clear explanation as to why people caught in an awkward
position or being caught in a lie, start to blush. Thereby sending a clear
signal to others: Here I am in front of you - a liar, a scoundrel, a liar. But
why? There is only a vague suggestion. Like, sending the paint on the face,
nature causes people to lie less. A red-faced liar sends a group of persons
surrounding the signal of readiness to apologize.
2. LAUGHTER
It is still not clear exactly what causes a person to
have fun. After all, a sense of humor at all completely different. The
assumption of scientists that laughter is needed to balance the mental
processes. For example, in order to dampen the excitement, tension and sadness.
Laugh creates real "biochemical storm" - is produced naturally
intoxicating substances - endorphins, antidepressants. No wonder the British
have a saying: "Teach me laugh - save my soul."
3. INTIMATE HAIR
During the evolution of man lost almost all wool. But
why has retained special thickening of pubic hair? After all, this place is the
most susceptible to parasitic infections.
4. THE THIRST CREATE WORKS OF ART
One simply can not create beauty. It pleases the eye.
But, usually devoid of any utilitarian purpose. And why is it necessary? The
assumption of scientists: beauty Let indirectly, but still helps a person to
create better utilitarian objects. For example, a comfortable environment and
people perceive more aesthetically attractive. And not comfortable - like a
hideous. Creating works of art, a man trains his brain, which improves the
process for solving purely applied problems. And maybe he was right, Lev
Tolstoy, who wrote: "... one word to another person transmits his
thoughts, the art people convey their feelings to each other."
5. SUPERSTITION
Rational sense in no superstitions. But they are.
Paradox? The assumption of scientists: the vitality take based on memorization
of luck and trouble forgetting. We become very superstitious when we have some
difficulties. Die to gloomy thoughts we are worse control our actions and make
new oversight. And then, all blamed on black cat. If the person passes the cat,
then give yourself installation that everything will be fine. It's kind of a placebo.
6. ALTRUISM
It is a unique human feature - live for others - laid
down in the brain. Already in the 18 months babies begin to show altruistic
behavior. With that said innate friendly person. But what makes people not even
to help relatives and without benefits for themselves? The assumption of
scientists: altruism is needed when choosing a partner. In both men and women.
7. HABIT PICKING HIS NOSE
Harmful like occupation - from the nostrils pulled out
the tiny hairs that help filter out dust and dirt out of the air we inhale. But
pick your nose everybody. Who secretly, who publicly. From children to adults. Disgusting?
Not at all. Some researchers have seriously believe that this is - a good way
to strengthen the body's immune system. Along with kisses. And at the dawn of
evolution, again, it could all be unique. When the kiss was not with anyone.
After all, the nose filters out a large number of various bacteria. In
addition, American psychologists argue that digital massage of the nasal
mucosa, stuffed with different receptors, improves brain activity.
8. KISS
How and why did the tradition of kissing, why had
sexual connotation, no one knows. Although the hypothesis fully. But what is
the most reasonable? The assumption of scientists: perhaps a kiss - in the
original is basically - a kind of vaccination method, invented by nature. Because
saliva contains various bacteria. 80% of them are the same in all people, and
20% are individual. When you kiss these bacteria are transmitted from person to
person. In the mouth, they cause the revival of other microorganisms, giving
impetus to the immune system and triggering the process of formation
antibodies.
9. LONG ADOLESCENCE
Even our closest relatives - the great apes do not
have such a long transition from adolescence to adulthood. Puberty occurs in
chimpanzees about 5 years old when they run out of childhood. The people also
called puberty lasts from 11 to 20 years. Why? The assumption of scientists:
adolescence - a later acquisition of the historic humanity. The duration of
puberty depends on the level of development of society. The higher it is, the
wider the band between the end of puberty, and the onset of final maturity.
10. DREAMS
Once our distant ancestors exist a firm belief: during
sleep the human soul temporarily leaves his body to wander around the world.
And we dream that she sees in his travels. Later Sigmund Freud claimed that
dreams are a reflection of our unconscious desires. But today, most researchers
reject it. But then why do we need them?
