The Neolithic revolution was a turning point in human history when Homo sapiens started the deliberate cultivation of plants and domestication of animals.
The Neolithic Revolution was the broad-scale shift away from a lifestyle of hunting and gathering to one of agriculture and settlement that occurred throughout the Neolithic period, enabling an expanding population. These evolved societies enabled people to study the growth and development of plants via observation and experimentation. Plants were domesticated and turned into crops as a result of this new knowledge.
Archaeological evidence suggests that different kinds of plants and animals were domesticated in diverse places around the world beginning in the Holocene 11,700 years ago. It was the first agricultural revolution in history that could be proven by history. The variety of foods that were readily available was significantly reduced during the Neolithic Revolution, which led to a decline in the standard of human nutrition compared to that previously attained through foraging.
There was much more to the Neolithic Revolution than simply adopting a small number of food production methods.
