Early humans becoming food-producers was a greater revolution than taming animals or making pottery.
This is because of the following reasons:
1. The early humans were hunter-gatherers. They moved from one place from another in search of food, water and shelter. The cultivation of crops was a shift as they no longer had to live a nomadic life. They settled near the fields. This made their lives stable.
2. The dependence on natural sources ceased. They produced their own food, on which they survived.
3. Taming animals and making pottery followed after the beginning of agriculture. These were required to sustain their agricultural way of life. Animals were used for grazing and also as draft animals. Pottery was required to store grains and liquids. These were not revolutions. Agriculture led onto the invention and practice of domestication and pottery. Thus, the foundation of civilisation was laid.
