Emergence of agriculture and writing Invention of writing
New challenges for humanity
Humans organized to face the new conditions they encountered in the places they arrived: other climates, new predators, even more primitive humans.
Faced with these groups, their superiority lay above all in the language
They also improved their tools: they added handles, for example, to improve their efficiency; They invented the rope, the hooks, the whistles, the baskets.
In cold areas, they needed animal skins to cover themselves
The first things that appeared were lines, circles and symbols carved in stones (petroglyphs); then small carved bone objects and, 30,000 years ago, cave painting on the walls
Creativity began 40,000 years ago par excellence: art.
Agricultural revolution
Why and how did they do it?
Due to a decrease in glaciation, the planet's climate improved, which in turn allowed certain grasses (herbs) to grow naturally
It also influenced some groups to observe that plants have a cycle: they are born, grow and bear fruit
the women began to sow the grains
Agricultural main cente

Eastern called fertile crescent that includes many countries today 10,000 years ago.
Northwest China, 7,000 years ago
Mesoamerica
Mexico and adjacent areas of Central America), 5,000 years ago
Andean America (today Ecuador and Peru), 4,000 years ago
Invention of writing: The development of cities and agriculture led to the growth of commerce.Sumerian merchants kept records of what they sold and bought on clay tokens in the shape of animals, jars, and other items they traded. Towards the year
3300 BC, they realized that they did not need figures and began to scratch with simplified signs on whatever surface represented the articles - that was the beginning of writing
Changes brought by agricultural revolution
Second change
The second big change was in housing: sheds and caves were not enough, as in nomadic life. They had to build the first houses, with whatever was available in the area: stone, mixed wood, etc.
Third change
The populations mastered the cultivation techniques: compost, irrigation, selection of seeds and conservation of surpluses, as well as the breeds of domesticated animals and the quality of the tools used.
Fourth change
The availability of more consumable calories brought the increase in population, the fourth big change. Biologists have estimated that the total world human population 10,000 years ago was between 5 and 10 million. After 8,000 years, this figure had grown to 300 million..
First change: The groups must take care of their plantations, harvest them and store the products they did not consume
