7 Biggest Mysteries of The Human Body

Man revealed many secrets about himself, but left a huge number of other questions, the answers to which we are still looking.One has only to guess why we need some bodies, the role played by microbes in our body and why the one hand is always more developed than the other?

Ques 1 – Why are we so weak?

shave chimpanzees and photograph his body from the neck to the waist, and then compare it with a photo of the same part of the human body, you will not find a difference. Musculature of these two kinds of living beings is almost identical, however, chimpanzees about 2-3 times stronger than a man.

While it is not clear why we are so weak in comparison with our closest relatives, perhaps the attachment of our muscles are slightly different, or our muscle tissues are not as dense.

Ques 2 : Why one hand we dominate another?

Nine out of ten people on the planet – right-handers. However, surprisingly, not only that the world has such a lack of left-handers, and the fact that a person with one hand – dominant. Why do we have one hand has an advantage over the other, not both hands have sufficient agility?

According to one theory, the dominance of one hand due to the fact that one side of our brain responsible for speech, more tortuous. And it also requires good motor skills. Since the speech center is usually located in the left hemisphere of the brain, which is responsible for the right side of the body, the right hand is dominant in most people.
However, this theory can not explain why not all right-handed control his speech with the left hemisphere. By the way, half of it is responsible for left-handers is the left hemisphere of the brain.

Ques 3 : Why should a woman have large breasts?

Breast women, like female apes, filled with milk only when they need to feed infants. However, women’s breasts, unlike breast animal is large enough and the rest of the time. Scientists are constantly arguing, why do women need such big breasts?

Most evolutionary biologists believe that the breast is used to attract the opposite sex. Men administered so misleading that a woman is able to surround the bust to be a good nurse for future offspring. In fact, most preferably consists of breast adipose tissue, and are not made ​​from milk.

Anthropologists meanwhile concluded that such women developed breast for themselves and for their children, and not to attract men, because in many cultures, men did not find breasts sexual.

Florence Williams, author of “Breast” (2012) suggests that women have larger breasts in order to satisfy the need for more energy is required to infants having a relatively large volume of the brain.

hormones that are in the chest, contribute to the accumulation of fat, which, in turn, falls in milk during breastfeeding. In other words, the fat from the chest helps to shape a child’s brain. However, it is still only a theory, which is waiting for more serious research.

Ques 4 : Why do we “intimate hair?”

theories about why the man pubic hair, there are many. Some scientists believe that these are rough curly hair sexual ornament – a visual signal of sexual maturity and reservoir for pheromones.

Others believe that the vegetation in intimate places protects these delicate parts of our body. There is also a view that the pubic hair are a bit of a “pedestal” to avoid friction during sex. However, no matter what those physiological features, most of us want to get rid of them.

Ques 5: Who lives in us?
Oddly enough, but part of our body really is not “ours”. Every cell accounts for about 10 microbes that live inside our bodies and a total of 1-3 per cent of total body weight.

Some “residents” of our body to help us to clean the skin, the other – to digest food, but features a huge number of microbes in our body have not been studied. In healthy people, there is a small number of viruses which, as it turned out, not only capable of causing disease, but perform some other function.

We recently learned that when antibiotics kill the beneficial bacteria in our gut, we can develop autoimmune diseases ( such as diabetes type 1). We few, we know about viruses.

Ques 6 : Why do we have an appendix?
This body in the form of a worm considered among evolutionarily useless remnants, among which also the wisdom teeth, the coccyx, etc. The appendix can be removed surgically without any apparent consequences.

However, biologists recently again raised the question of the function of the appendix. Some believe that it helps to train the immune system during fetal development. Other researchers suggest that the body serves as a “safe haven” for the bacteria that aid in digestion. It hides microbes that colonize the newly gastrointestinal tract after any problems.

Ques 7 : The biggest mystery – is the brain
How 100 trillion neural connections in our brain work together so that we can feel alive? Many great minds think that consciousness – the biggest mystery of our body.

Neuroscientist VS Ramachandran once remarked:

“The brain of any creature, including yours, is made ​​up of atoms that billions of years ago were part of a massive star. These particles drifted for many years and endured incredible distances before gravity and randomness does not put them together.These atoms are now a conglomerate – your brain, which can not only think of these stars, but also the ability to think about the most, as well as its ability to be surprised to be surprised. With the advent of the human universe suddenly became aware of herself.This is the biggest mystery of all. ”
