In the paleolithic Age people only had resources that were close by.
In the neolithic Age there was trade. This change was important to get/ grow other resources and to figure out different uses for these resources.
In the paleolithic Age people lived in small groups since they were always moving to find food. Also because there were no farms.
In the neolithic Age people lived in bigger groups because they invented farms so they didn't have to move. They divided the work to produce food and other things they needed.
In the paleolithic Age they moved to find wild animals or new plants to eat (called nomads). The nomads also lived in caves or rough tent like structures so they can keep moving and not permanently be somewhere.
In the Neolithic Age people stayed in one place. They built there home by packing mud bricks together, they also had rooms to put their food built into the floor.
