It is known as a long period of prehistory in which the power of transformation that man has on the environment has not yet come to create the need for writing. It is therefore the economic factor that marks the transition from prehistory to history. 

In the Paleolithic, humankind is beginning to emerge on Earth, working rudimentarytools. The mode of production practiced during this period was the collection of waste, hunting, gathering or fishing of the natural ecosystem. No such plants or domesticated animals, and grouped hominids lived in small family bands or clans that occupied a large area of hunting and gathering. 
Trade was known from the Paleolithic, in which exchanges were made and, if initiated by the applicant ofthe product and in return used to offer to the seller any ornaments or magic charms. 

During the Neolithic, it was possible to better control the reproduction of plants and animals through the development of livestock and agriculture. This laid the material foundation for the emergence of dense sedentary settlements and rapid population growth. agriculture and livestock setthe stage for profound changes in the domestic economy and the policy focused on access to land, water and other basic resources and the emergence of differences in wealth and power. Without agriculture there had been no development of cities, states and empires. 
 technological achievements included the spinning and weaving, pottery, smelting and casting of bronze, burnt brick, masonry arches, thepotter's wheel, sailing ships, the first wheeled vehicles, writing, calendars to compute the time weights and measures, and early math, and for the first time, human communities were divided into rulers and ruled, rich and poor, individuals who are literate and illiterate citizens and farmers, artists, warriors, priests and kings. Another factor that contributed to a village were to become thecity was the trade in raw materials and finished products, including local merchants and others from remote sites. 
Around 700 BC, the invention of coinage made the trade became popular. With the nascent industry of the exchange of goods, ie trade. 

Used new inorganic materials such as coal and oil. Other important raw materials were wood, with whichthey built ships and cotton, where the thread was removed for use on the looms. 
Coal is the energy source used in this phase for excellence as it was the fuel of the steam engine, the great machine discovered in this stage (1785) by James Watt. The industrial revolutions came to get that production was more rapid and abundant. 
The protagonists of this stage are the bourgeoisie and theworkers. The first were the rich, while the latter worked 14 hours a day throughout the week. 
There was a mechanization that wanted to eliminate the labor being done by humans through a machine that performs the same function. The most important machine is the steam engine, which influenced the transport, manufacturing, among others. The objective of this stage is to produce long and expensive. Thisindustry depends on the inventions of the era and the most developed are the steel and textiles. 
Steel, underwent many changes, how the use of coke, puddling, and steel fabrication. 
Textiles, suffered significant changes, depending on the improvements of the machines. 
It appears the private and public property. Industrialization began in England, spreading to Western Europe, USA and Japan. 
Atthis time the culture is a privilege, and only people with money have the opportunity to be educated. 
At this stage appear petroleum-based raw materials and others that come from nature. It deals with the chemical raw materials, like plastic and other types of tissues to be used in the textile industry. Wanted  automation. 
At this stage, continue to...
