Answer and Explanation:
Archaeologists and historians believed that human beings ceased to be nomads and began to settle in permanent homes after the agricultural revolution. This made human beings realize that it would be better to live in one place and plant their own food, than to hunt. This proved to be very useful for the civilization that was beginning to establish itself, however, in order to practice productive agriculture it was important to establish the division of labor, where each member of the community would be responsible for a certain function that would work in harmony with the other members.
This division of labor promoted rapid agricultural production, allowing the food produced to feed the community and be left over, promoting a surplus of food. This generated the first steps of the trade and a somewhat rudimentary economy, but very efficient to follow the human evolution over the years.
