Answer:
The adoption of agriculture (the Neolithic revolution) brought massive changes to human societies. Historians often point out that the Neolithic was the most important revolution in human history.
Step-by-step explanation:
In the social aspect, agriculture increased division of labor, and led to the development of hierarchies: some people accumulated wealth and power, and became the upper class, while others continued to be poor, and became the lower class.
In the economic aspect, agriculture increased the economic output that societies produced. This facilitated population growth, because the higher production of goods and services supported more people.
Finally, cultures also changed. From typical nomadic or semi-nomadic cultures, agricultural societies evolved into sedentary cultures, in which more elaborate forms of art began to flourish.
