The Neolithic time was about 10,200 BC and ending between 4,500 and 2,000 BC. The Neolithic Revolution or Agricultural Revolution, was the wide-scale transition of many human cultures from a lifestyle of hunting and gathering to one of agriculture and settlement. Farming of domesticated species created food surpluses that made possible to handle an increasingly larger population especially around fertile areas. These settled communities permitted humans to have workforce available for other activities, not hunting and gathering. Hence agriculture was the key development in the rise of human civilization and the product of the Agricultural Neolithic Revolution was advanced civilization with pyramids and temples (Mesopotamia, 6,000 BC, Egypt, 3,000 BC). An essential role played the development and planting of the first cereal crops, which satisfied much more people and provided much more energy to the workforce than berries, fruits and vegetables. In addition, cereal crops are easy to handle and store. Since then, cereal crops are our staple food.
