Back in Paleolithic times, the people were called nomads. What this means is they were hunters and gathers and never stayed in one place. They were made up of groups of 20 to 60 people. They ended up in caves most of the time and created the drawings or cave paintings we have today.
Back Neolithic Times they would live in communities. in these communities they each would have a specific job. They could do this because they had a stable food supply and protection.
Now in the present, we live in families and live in big city's to suburbs to rustic county land. All because of the diplomat of agriculture.
Back in Paleolithic times, they would trade but with a small number of things. Like rocks, herbs or certain grass.
Back in Neolithic times, they would trade with better items. Like fruits, vegetables, and tools, weapons.
Now in the present, we have local supermarkets, toy stores, and tool stores.
