GENERAL KNOWLEDGE

Detailed explanation-1: -Rather than relying primarily on hunting or gathering food, many societies created systems for producing food. By about 10, 000 BCE, humans began to establish agricultural villages.

Detailed explanation-2: -How did the social structure develop in settled farming villages during the Neolithic Revolution? Men began to dominate social, political, and economic life. How did food surpluses change the way of life in early human settlements? Villages needed to organize governments.

Detailed explanation-3: -Agriculture allowed people to stay in one place, and increased food production caused the population density to expand far beyond levels that could be sustained by hunting and gathering alone. This growth in population density provided a critical mass of people to sustain and spread contagious infectious diseases.
