What are some 4 changes during the neolithic age

Hello!

The New Stone Age, or Neolithic Age, was a major evolution for humans in terms of survival methods and developments in society. 
Four major changes include:
1) Farming
2) Domestication
3) Development of new skills and technologies
4) Sedentary lifestyle

People took a major step forward when they discovered that they could plant and grow seeds. In addition, they discovered that they could domesticate and herd animals. These two discoveries allowed people to live a sedentary (settled) lifestyle rather than being nomadic. Before the Neolithic revolution, people lived a very nomadic lifestyle and moved constantly due to the way that animals migrated. People needed to follow the animals in order to collect food. With the development of farming and domestication, people could finally live a more sedentary lifestyle because they did not need to constantly follow their food source. Lastly, people developed more skills and technologies. One example is that people began creating more task-specified stone tools, rather than simply sharpening a rock (for example) that had been used during the Paleolithic period.
