The Neolithic Age (B.C. 8,000 - about B.C. 1,000) is a period when mankind adapted themselves into the changed natural environment after the Ice Age, made new earthwares and ground stone tools and began settlement. There are about 400 Neolithic Age ruins found

throughout Korea in the form of house relics, tombs, shell mounds, etc. The most well known ruins include Amsa-dong (Seoul), Osan-ri (Yangyang, Gangwondo), Dongsam-dong (Busan), etc. The Neolithic Age people built dugout huts around seashores or riversides where water

and food were abundant and went fishing, hunted and collected wild plants. In this period, a crude form of agriculture was introduced as people cultivated Italian millets and common millets. Grounded stone tools and bone allowed them to effectively get food while earthwares

helped them to store and cook foods. They wore simple forms of clothes made up of weaved threads or animal skins and decorated themselves with jade, animal bones, horns, and shells, etc. Also, they were actively engaged in an interchange with various groups

around the Japanese archipelago, Northeast China, and the Maritime Province, etc.
