The Neolithic Revolution

Impact of the Neolithic Revolution
The Neolithic Revolution was the first agricultural revolution. This was when big changes in society, farming, government, religion, domestication, and the growth of cities began to occur.
At the end of the Ice Age, changes in plant and animal species began. Some plants that were alive during the Ice Age died, as well as certain species of animals. In Southwest Asia, wild grains grew and the people would gather them to start their own crops. This is how they learned how to farm. They learned how to domesticate certain plants by saving the seeds from the most essential plants and planting them to reproduce more. As a result, food production grew considerably.
People also started to domesticate animals. It is apparent that the first domesticated animals were dogs, as they made great hunters and protectors. They also domesticated sheep for wool, cows for milk, and other animals that provided the best sources for them. By domesticating animals they were able to create a steady production of skins and food.
Because of these changes in agriculture, the population grew tremendously. The lifestyle of the population also began to change as well. Some people would live off of a selected livestock, like their own farm, depending on their own meat and crops to survive. These people were called pastoralists. (Ramirez et al 15) Others lived in collected groups, settlements, combining their work, animals and crops. At around 6000 BC these settlements grew to villages and towns all over the world.  
Lifestyles changed even more when people started to make tools for convenience. Such tools included grindstones and pestles to help them grow crops of grains and other plants. They also began to make clay and pottery for storing food. (Neolithic 'revolution' paragraph 2)With the discovery of metal they were able to make their tools harder and stronger, therefore making them more productive.
