In the Paleolithic Age, we didn't have many jobs available. The only jobs we had were hunters and gatherers. The job of the hunter was very dangerous and the job of a gatherer only had so much food they could collect.
In the Neolithic Age, we were able to have more specialized jobs. These jobs came because of the job of farmer. Some of the more specialized jobs included weavers and tool makers. Some of these jobs also were able to keep us safer.
Another job is that we have now is a builder. They build the things in our community. We also have basket makers that can make the baskets to transport food and other products to other places more easily.
This change was important because it allowed us to make our world more beautiful. We were able to be safer and have more conveniences.
