How did the neolithic revolution contribute to the rise of early river valley civilizations?
The Neolithic Revolution led to the development of agriculture, which allowed for a more stable food supply. This surplus of food enabled populations to grow and settle in one place, leading to the formation of early river valley civilizations along rivers such as the Tigris and Euphrates in Mesopotamia, the Nile in Egypt, the Indus in India, and the Yellow River in China. These civilizations relied on the fertile land provided by the rivers for agriculture and trade, ultimately contributing to their rise and prosperity.
