<em>The human being was evolving</em> in terms of physiognomy, physical abilities, incorporation of new techniques and technologies, development of forms of communication, social organization and various cooperation mechanisms.
When the ancestors of homo sapiens managed to walk in a bipedal manner, this allowed them to travel great distances across the African savannah in order to obtain food or escape from predators.
Being able to stand on his legs, his hands were left free to manufacture and carry weapons and tools increasingly sophisticated.
It was very important to discover the techniques of domination over fire, which allowed man to protect himself from nocturnal beasts, to see in the dark, to have heating and above all the possibility of cooking his food, thus generating a greater assimilation of the nutrients and allowing great advances in cognitive development and population growth.
Once man could dominate agriculture and livestock, a great change was made in the way of life and social organization that we call the Neolithic Revolution. It is at this time when the first sedentary communities emerge and then the cities, kingdoms, etcetera.
When the cities became more complex and their organization was more structured, the first written codes began to appear in the form of tablitas of engraved clays.
Tablillas were used to promote commercial exchange, tax collection, the establishment of laws, the development of poetry and religious writing, etcetera.

The development of writing in turn allowed the deployment of various areas of knowledge such as mathematics, astronomy, administration. They continued incorporating new technologies such as irrigation, tillage, wheel, mill, and civil construction, clothing.
The Neolithic Revolution occurred first in the fertile growing corresponding to the plains bathed by the Nile River, the Mesopotamia watered by the Tigris and Euphrates rivers, then in the Indus valley and in the region today belong India (Indus and Ganges rivers) and in the Far East (Huang He and Yangtze rivers in China).
In America a parallel situation arose and in the rest of the world these advances were expanded by diffusion from these territories.
Other great revolutions that changed the life of man can be the Scientific Revolution, the Democracy, the Industrial Revolution, the Information Revolution, and we are waiting for new advances to come.
