Explanation:

The Neolithic Revolution was characterized by the shift from hunting - gathering to agriculture. With the development of agriculture, human societies could settle in one place as they no longer needed to follow animal herds for food. This led to the formation of the first river - valley civilizations. Option A is incorrect as river - valley civilizations were large, not small and independent. Option B is wrong because life became more complex with specialization. Option C is not related to the formation of river - valley civilizations in the context of the Neolithic Revolution.
