The advent of agriculture as a primary means of subsistence signaled a change in what aspect of human social structures?

The first change brought by the advent of agriculture to human social structures, due to the manner of exploitation required by this activity, was that it triggered the establishment of sedentary settlements. This meant the start of the Neolithic period, in contrast with the nomadic lifestyle in the former Paleolithic era.

Agriculture and sedentarism also brought specialization and division of labor. Specialization allowed to improve the instruments and tools used for each activity (agriclture, animal husbandry, hunting, etc) and therefore productivity was rapidly enhanced. For the first time in history, men in Neolithic tribes produced more than they could consume.

This was the starting point of intentional contact betwen prehistoric clans, because they started to trade their respective production surpluses with each other. Until this moment, each tribe had been been self-sufficient, but the development of the new social and economic structures gave rise to this turning point moment in which commercial activities started to take place.
