How did the agricultural revolution lead to an increase in human population numbers?

1. The shift from a nomadic lifestyle to settling down on farms with domesticated animals allowed for nutritional needs to be met more easily.

2. The discovery of medicines, such as antibiotics, allowed us to live longer.

3. Farming allowed for the discovery of pesticides, which allowed for better food production.

4. Industrialization and manufacturing allowed us to produce more food.

The first option is correct. The agricultural revolution allowed early human societies to settle down in one place, and rely on domesticated crops and animals for their needs. This led to a stable food supply, which in turn allowed for population growth. People were now able to produce more food than necessary to sustain themselves, allowing them to support larger communities and families.
