Which of the following contributed to the start of the neolithic revolution? a. the beginning of job specialization b. the formation of governments c. the growth of cities d. the warning of the earth's climate

The correct answer is D) the warning of the earth's climate.

What contributed to the start of the Neolithic Revolution was the warning of the earth's climate.

The Neolithic Revolution was a turning point in the history of humanity. Humans stopped being nomads and started to settle in one place. They learned agriculture techniques and started to grow crops to feed their families instead of following the herds to hunt animals. For instance, the oldest civilization, the Sumerians, settled in between the Euphrates and Tigris Rivers and established powerful city-states such as Nippur, Kish, Ur, Lagash, and Uruk.
