In the Paleolithic Age we would go out and hunt for animals and crops.
We learned how to grow and farm food because hunting for animals and crops is dangerous.
Unlike the Paleolithic Age us in the Neolithic Age have learned how to grow and farm food.
In the Paleolithic Age we didn't really trade all we really had was what was around us.
This change is important because we get to trade for things that we need and wouldn't be able to get ourselves.
During the Neolithic Age we would trade for better things or things that we would need that is useful to us.
The hunter-gatherers would use caves or rough, tent-like structures for a shelter. They were temporary because they have to move so they could follow the wild animals or find different/new plants that they could eat.
During the Neolithic Age we would make our permanent shelters out of mud bricks to form the structure and form it into a round or rectangular house. We also used stones and tree branches to strengthen the walls or the roof.
Shelters during the Neolithic Age are permanent because we have farms and so we don't have to move around a lot.
