The Paleolithic Age people had to hunt and gather food. (instead of going to stores and buying food) They also had to live in the same home as other people. They learned how to hunt in groups and they discoverd fire. During this period, people began to spread around the world.
The Neolithic Age began about 11,000 years ago when people discoverd farming. People also began to settle in one area, and started to domesticate animals.
Today, we have lots of stores to shop in, and money to make. We can take care of kids and be able to survive by ourselfs. We live in families now, and we celebrate holidays.
