The major changes in the lives of the Early Stone Age People as they moved into the New Stone Age was that they used farming. Early Stone Age people moved around a lot while they were hunting and gathering food and focusing on survival. Then came the New Stone Age people who set up more permanent homes and started farming. They also started to set up civilizations and used fire. Stone tools were used for farming. I think some important developments that allowed them to begin to create civilizations were that they started farming, used fire, and settled down in more permanent homes. People changed because of their environment
Early Stone Age people had to keep their focus on survival, and so they spent much of their time hunting, gathering plants to eat, and making tools. Because they depended on their immediate environment to provide food for them, they had to move a lot to follow animal herds and find new sources of nourishing plants.
This meant they didn’t build homes and settle down. They often lived in caves and wandered from one to another when they needed to. Caves gave them a safe place to raise children, protection from weather and wild animals, and a place to store food. Places inside the caves were hollowed out to keep food safe from animals. At night or during storms, people rolled huge stones across the opening of the cave for even more protection. If they couldn't find shelter during their travels for food, they had to live outside in the elements for a while.
