Tip 1: How did humanity appear
According to modern scientific ideas, from the momentthe escape of man from the animal state to the formation of modern mankind has lasted from two to five million years. The formation of society was slow and gradual. In the course of evolution, the person changed externally, along with this, relations within the community changed, thinking and speech developed, without which it is impossible to imagine civilization.

Archaeological finds give groundsto assert that humanity began to form more than two million years ago in eastern Africa. But there are separate finds that allow you to postpone the date of separation of a person from nature for another two or three million years into the past. In those distant times, the slow transition of man's ancestors from the arboreal to the terrestrial way of life began.

Originating in one place of the planet, humanity inFor many thousands of years it has spread over other continents, mastering new habitats. The main factor that triggered the migration was a sharp change in climatic conditions and impoverishment of the animal world. In search of sustenance the ancestors of modern man were forced to master the uprightness and move to remote regions.

For several millennia extensivethe territory of Asia, Europe, Australia and Oceania. Lastly, about 35 thousand years ago, a man settled on two American continents. At that time, the foundation of the existence of human society continued to be gathering, hunting and fishing. Tribes most often led a nomadic way of life, because they depended on the migration of animals.

Change in people's way of life affected theirdevelopment. Approximately 40 thousand years ago, a person gained that appearance, which has survived to the present day. Everyday activities contributed to the development of complex work skills, thinking and speech. Language became the means by which it became possible to transfer knowledge and accumulated experience to other generations.

The transition to a sedentary lifestyle opened a new stagein the formation of mankind. The most developed nations began to move away from hunting, switching to farming and farming of domestic animals. This is the first division of labor in the history of mankind. Agricultural activities have significantly reduced the dependence of man on nature and hunting luck.

Approximately in the 4th millennium BC beganForm the first known in the history of civilization. The basis for them were the largest and fertile rivers of the world - the Euphrates, the Tigris and the Nile. The climate favorable for agriculture contributed to the development of human economic activity. In society began to conceive the beginnings of the state, a stable social structure was formed. In Mesopotamia and Ancient Egypt, mankind for the first time passed from the primitive state to a class society based on slavery.
Tip 2: How life on Earth goes
In the early stages of the existence of the planetthe development of a lifeless geosphere-the Earth's shell. Its appearance was influenced only by earthquakes, volcanoes, movements of the earth's crust, etc. With the emergence of life, living matter slowly and weakly at first, and then began to influence the geological processes of the Earth more and more rapidly and significantly.

1
At first, living organisms ate organiccompounds of the primary ocean. As a by-product, carbon dioxide was released into the atmosphere. When the stocks of the ocean were depleted, microorganisms that could synthesize organic compounds from the hydrogen present in the atmosphere and the carbon dioxide stored in it were given an advantage.
2
As a result of the activity of these microorganisms, methane was released into the atmosphere. Under the influence of ultraviolet it again turned into organic compounds and returned to water.
3
When the reserves of hydrogen in the atmosphere were depleted, photosynthesis became a new source of energy. In the first photosynthetic bacteria, it proceeded without the release of oxygen.
4
When there were organisms with more perfectthe mechanism of photosynthesis, oxygen began to be released into the atmosphere. For living organisms of those times (mostly anaerobes), he was the strongest poison. In the end, it was not only "neutralized", but also began to be used to generate energy - so there was oxygen breath.
5
In the upper layers of the atmosphere, oxygen under the action ofultraviolet rays turned into ozone, and as ozone accumulated, a reliable ozone shield formed to protect the planet from a harmful ultraviolet. Due to this, living organisms reached the land and settled it.

The processes of synthesis are continuously occurring in the biosphereand the decomposition of organic substances. The cycles of these substances ensure the stability of the functioning of the biosphere. The equilibrium between the processes of decay and synthesis was established at the end of the Mesozoic - the beginning of the Cenozoic, and about 2.5 million years ago the first people appeared. Now mankind creates an almost artificial environment for its habitat, and the anthropogenic factor has become a powerful driving force in the evolution of life on Earth.
Tip 3: Love and hate - Body positive
Generally recognized beauty standards are being asked todayhuge demands for both men and women. Not so long ago, the advertising campaigns of many brands were quite aggressive. Many cosmetic companies do not consider it shameful that the wrinkle cream advertises a model that was barely 18. The old age is a shame.
From everywhere there is an imposition of brands, trends. Hollywood actors and their body cult. Fashion industry and 90h60h90. All this in turn prompted many people to go to plastic surgery, which caused a huge number of their victims. There were many diseases caused by the desire to become perfection. The number of deaths is as if it were a war.
Against the background of all this, there were already manysocial and social reactions. One of them was the movement of Body Positive, (body-building in our way). The first time you encounter a body kit, you can experience a shock. Along with the calls to accept your body as it is, do not pay attention to the negative opinion of others, love yourself, there is aggressive aesthetic extremism in this movement. This, in turn, causes a huge wave of haters. And now they have already grappled: "I love the body kit!", "I hate the body kit!"
But if you look at all this sensibly, then right andthose, and others. Do not enter into this polemic. This is just a reaction of society to the imposed ideals of beauty. People are just tired of falseness and substitution of concepts. Glossy magazines, TV screens simply are full of ideal bodies. But even the models themselves are not perfect. It's unquestionably beautiful people, but not ideals. Everything is achieved by means of image processing.
The society made a loud signal about the refusal of thethis. And this signal was heard. Companies that are smarter, deployed their advertising torpedoes from the ideal to the person. The American Film Academy has distributed "Oscar" to actors and actresses who were not afraid to look like everyone. Models of forms + on the podium now no one surprises. With such a tendency, mankind will finally return to accepting naturalness and such extreme protests as those of zealous bodybuilders will simply disappear by themselves.
