EMERGENCE OF AGRICULTURE
New challenges of humanity
Humans organized themselves to face the new conditions they found in the places they arrived: other climates, new predators, even more primitive humans.
They also improved their tools: they added handles, for example, to improve their efficiency; they invented the rope, fishing hooks, whistles, baskets.
In the cold areas, they needed animal skins to cover themselves and to hunt better; they invented the spear, the bow; and, to separate the flesh of the skin, better burins, chisels and flint knives.
Creativity began 40,000 years ago par excellence: art. The first things that appeared were lines, circles and symbols carved in stones
Agricultural revolution
Most people in the world changed their lifestyles about 10,000 years ago by adopting some form of agriculture.
Why and how did they do it?
Due to a decrease in the glaciation, the planet's climate improved, which in turn allowed certain grasses (herbs) that grow naturally will spread across the steppes.
Agricultural main centers
The crescent-shaped strip of land located in the eastern Mediterranean (called the Fertile Crescent, which includes the current countries of Iran, Iraq, Israel, Jordan, Syria and Turkey), 10,000 years ago
Northwest China, 7,000 years ago
Mesoamerica (a term applied to central and southern Mexico and adjacent areas of Central America), 5,000 years ago
Andean America (today's Ecuador and Peru), 4,000 years ago
Changes brought by agricultural revolution
The second big change was in housing: branch sheds and caves were not enough, as in nomadic life.
The populations mastered the cultivation techniques: fertilizer, irrigation, seed selection and conservation of the surpluses
The main and immediate change that agriculture brought the sedentary. Groups had to look after their plantations
The availability of more consumable calories brought the increase in population, the fourth big change.
Invention of writing
The development of cities and agriculture led to the growth of trade. In one of these cities, and for hundreds of years.
