Do you know about all the secrets that our body keeps? If not, then this article will reveal some of them. Believe me, you will be surprised … Here are seven of our body's biggest secrets.
Where does this power come from?
“If you shave a chimpanzee and photograph its body from neck to waist, you won't notice at first glance that it's not human,” says Kevin Hunt, director of the Human and Primate Evolution Laboratory at Indiana University. Hunt argues that the musculature of the two species is extremely similar, but somehow chimpanzees are two to three times stronger than humans.
It is also unclear why humans are so much smarter than their closest hominid relatives. In terms of strength, it is possible that the muscle attachment points are subtly different, or the human muscle fibers are less dense. In any case, the reason is unclear.
Once in an African forest, Hunt watched a female chimpanzee break branches of a very sturdy tree with her fingertips. To break such a thick branch, a hunter would need both hands and maximum strength.

On the other hand…
Nine out of 10 people are right-handed. One theory is that hand motility is mediated by complex neural connections on the side of the brain involved in speech. Since the speech center is usually located in the left hemisphere of the brain, the side associated with the right side of the body becomes dominant in most people. However, this theory fails due to the fact that not all right-handers control speech at the expense of the left hemisphere, while left-handers do. Strange, isn't it?
Pubic hair
There are several theories regarding this issue. Some scientists argue that these sexual ornaments are a visual signal of puberty and a reservoir of pheromones.
Others think hair provides warmth and protection to the genitals. Still others claim that they serve as a kind of supplement, preventing skin irritation during sex. Be that as it may, many modern people want this add-on to disappear.
Chest
Like all female monkeys, a woman's breasts are filled with milk when a baby is born to her. But only women at all times strive for splendor of their breasts. Scientists cannot agree on what the breast serves for a woman. Most evolutionary biologists believe that she acts as an attraction for men, who are deceived into thinking that a woman with large breasts will feed their children well.
Anthropologists, meanwhile, tend to think that women's breasts are developed for babies rather than men, noting that in many cultures, men do not find large breasts sexy.
Florence Williams, author of Breasts (WW Norton, 2012), believes that a woman's breasts enlarge to meet the energy needs of her baby's brain. Hormones in the breast promote fat storage, and this stored fat is released into milk during breastfeeding. “Breast fat supports the formation of the baby's brain,” Williams said. But the theory has not yet received universal acceptance.
Microbes
There are ten microbes living in each of your cells. Some of them provide skin cleansing, while others help to digest food. But the bulk of these microbes contribute to our physical function. A healthy body even contains a number of harmful viruses that seem to serve the body in some way.
The consequence of taking antibiotics is that a person gets rid of the good bacteria in the intestines and thereby provokes the development of an autoimmune disease such as type 1 diabetes.
Humanity is not so advanced in its understanding of viruses. How are they useful? Vincent Rachaniello, professor of microbiology and immunology at Columbia University, says: "It's clear that we have subscribed to a whole bunch of symbiotic processes and have no idea that we are breaking a deal with nature."
Appendix
The poor old human body contains such evolutionary remnants as wisdom teeth, appendix, etc. The latter organ is of particular interest to scientists.
This vermiform organ, most likely, can be eliminated without obvious loss to human health. But more recently, biologists have begun to question the notion that this application to the digestive system is meaningless. Some believe the appendix helps in maintaining the immune system during fetal development. Other studies indicate that this scion is home to beneficial bacteria that aid in digestion.
Human brain
How do the 100 trillion neural connections in our brains work together to make us feel alive? Many great thinkers consider consciousness to be the greatest secret of nature.
Neurologist V. S. Ramachandran said, “One brain, including the human brain, is made up of many atoms that were forged in the hearts of countless distant stars billions of years ago. These particles have drifted over eons and light-years of gravity and now form a conglomerate - our brain, which can not only think about the stars that gave birth to it, but also reflect on its own ability to build logical chains and wonder about its ability to be surprised. With the emergence of man, the universe suddenly became aware of itself. This is truly the greatest mystery."
