Man in terms of strength and physical fitness gives way to many animals. However, it has a feature, which provides him with an advantage over them – It is a lack of specialization. His intelligence allows him to quickly adapt to changing conditions. In the city, he is rarely forced to develop data by nature. Hence, the primitive people who are in wild nature were more masters of their existence than their descendants addicted to civilization.
Smell
Man has a fairly well -developed sense of smell, Although it is not so perfect, Like, for example, in dogs. In natural conditions, the smell allows you to find food, warns about the presence of other creatures, against dangers, such as, for example, a forest fire.
Hearing
Wild animals were called to listen to the sounds that mark the potential danger. Urban being, which is a modern man, lives in an environment contaminated by noise, who dulls his hearing sensitivity and makes deaf to many sounds of nature.
Taste
Flavor mugs on the tongue allow you to distinguish four flavors – sour, sweet, salty and bitter. The brain receives stimuli sent from taste buds and nose, which allows you to determine the taste of a given food.
Respiratory system
The brain decides about the frequency of subsequent exhalation and breaths, which he recognizes, what is the body's demand for oxygen at the moment. Man breathes faster in moments of stress and increased effort and at considerable heights, where the diluted air contains less oxygen.
Spine
Straight attitude, which distinguishes man from other animals, causes a significant load on the spine, which causes frequent diseases.
Thumb
In man, the thumb is opposite to the others, independently bent fingers, which determines hand grip. This evolutionary achievement allowed man to create complicated tools, why he largely owed his possibilities to adapt to various conditions.
Ponds
Some joint connections, such as a knee joint, are by nature weak and exposed to injuries. In cities, where people have very little movement, not practiced ponds become -even weaker.
Feet
The weight of the whole body rests on the feet. Hence, they happen quite often, Especially during hiking, foot injuries. They are very troublesome.
Brain
A large and developed brain in humans allows him to equalize the deficiencies resulting from the imperfections of his other organs and senses. Thanks to him he can think logically, learn based on experience from the past and draw conclusions for the future, and philosophize trying to determine your place in the universe.
Sight
The field of human view is about 210 degrees, but 120 degrees are a field of two -pitched view, which gives the effect of three -dimensionality and enables reality to assess the distance between objects in space. Man also has the ability to see the whole spectrum of colors of sunlight – from red to purple.
In order to
Human teeth and jaws are adapted to bite meat, as well as for crushing and chewing plant foods. Thanks to this, man is a creature at the same time plants and carnivorous.
Heart
Heart, by pumping oxidized blood distributed by blood vessels throughout the body, Supports all organs in the life -giving oxygen. However, when he is not forced by physical exercises to regular effort, loses efficiency, which reduces our overall efficiency.
Skin
It protects internal organs, And thanks to the sweat glands, it regulates body temperature. Human skin, Deprived almost completely in the long evolutionary hair process, requires additional protection – clothes.
Species "man"
Man has been much worse by nature compared to many other creatures compared to many other creatures. In the wilderness it can easily become a victim of predators. Has weaker eyesight and smell than most natural hunters, Nor does it develop such a speed as many of them. He cannot maintain the right body temperature in a stricter climate, If he loses clothes. After all, it was man who has made one of the best -adapted creatures to life on earth. He had to compensate for numerous weaknesses and deficiencies of the body by developing his intelligence – The best weapon in the fight for survival.
