What is the first and second social division of labor?

At a certain stage of development, the primitive communal model of economic development led to significant changes, which was expressed in the division of labor.

The first social division of labor took place in the Neolithic period, and was expressed in the fact that pastoralists and farmers emerged from the general groups of tribes. This led to the transition to a sedentary lifestyle, and the possibility of accumulating wealth.

The second division of labor was expressed in the fact that craft was separated from agriculture. Ultimately, this led to the development of exchange, and subsequently to the emergence of trade.
