Dear Student,
In search of food, early man had to go from one place to another. Earlier, early man used to eat fruits from tree or roots of plants. Then early man started hunting animals for food. With the change in the climate, the plants and animals used for food also witnessed some changes. Men, women and children observed several things related to plants, such as places where edible plants were found, how seeds broke off stalks, fell on the ground and new plants sprouted from them. Perhaps they started protecting the plants from birds and animals so that they could grow and the seeds could ripen. In this way, people became farmers.
