how did farmering change the ancint man from nomade to a settler

The climate of the world was changing, and so were plants and animals that people used as food. Men, women and children probably observed several things: the places where edible plants were found, how seeds broke off stalks, fell on the ground, and new plants sprouted from them. Perhaps they began looking after plants, protecting them from birds and animals so that they could grow and the seeds could ripen. In this way people became farmers.When people began growing plants, it meant that they had to stay in the same place for a long time looking after the plants, watering, weeding, driving away animals and birds. This changed the hunters into settlers.
