This paper aims to rethink and reflect on the change in the of way of life and its inner logic that happened during the transition from the Paleolithic Age to the Neolithic Age, taking materials from Eastern Asia as its base. As is known, the Neolithic Revolution is widely called Agricultural Revolution. However, the author proposes that we should not use agriculture as an indicator of the Neolithic Revolution, for it is just one of the by-products of humans changing their ecological niche. In actuality, the onset of the Neolithic Revolution is the warming of the climate after the last Glacial, with the consequent increase of the importance of water in humans’ lives, triggering the change. Coping with the changes in climate, some groups begin to consume aquatic animals such as fish and waterside fowl. Consequently, there appears a tendency to miniaturize stone hunting tools and other utensils. Meanwhile, in order to meet the demands of fishing development, people in forested regions try to make wooden boats, bringing out the new technique of polished stone vessels. This paper is going to make it clear that there is a close relationship between the emergence and progress of the microlith and the miniaturization of hunting targets (fish and fowl). Furthermore, the use of timber creates the need of polished stone vessels, which first appear in places where humans begin to make dugouts. It thus becomes clear, why the technique of polished stone vessels is not advanced in these cultures lacking in fishery and timber industries. Human groups relying on fishing for subsistence gradually adopt a semi-sedentary or sedentary lifestyle in such places where streams are mild and wide, leading to rich and varied aquatic animals and plants. As time goes on, they include other types of food into their diet, among which are also cereal crops. Finally, demands of gathering and processing cereals lead humans to invent first pottery techniques. This paper is going to emphasize that the invention of pottery goes hand in hand with the waterside lifestyle and cereal crops gathering. In addition, archaeological data from East Asia suggests that people started using rice for making low-alcohol wine earlier than for cooking, and its role as a staple food is a later phenomenon due to increase in production volume. What we call the Blue Revolution is precisely such transition from a hunting lifestyle to a fishing lifestyle, which allowed human groups to settle down and discover cereals.
