| Outline of Final Research Achievements |
Seed impressions were found on pottery excavated from the Eriana site, where settlements were located during the Middle, Late, and Final Jomon periods, and through the cast and identify the species of the impressions by the replica method, 1160 seed impressions could be extracted. We found that the genus soybean, which became large in the Middle Jomon period, appears to have been continuously used until the Final Jomon period. We were also able to confirm the emergence of common millet and foxtail millet in a detailed pottery-type stage at the end of the Final Jomon period. It is significant that large soybean species were found at the same village site from the Middle to the Final Jomon period. In addition, carbon and nitrogen isotope ratio analysis of charred material attached to pottery vessels confirmed the emergence of functional differentiation of plant food preparation in large and small deep-bowl pottery vessels of the Middle Jomon period.

研究成果の学術的意義や社会的意義 300字
縄文人とマメ類のかかわりはその初期段階から深いことが、最近のレプリカ法による土器種実圧痕の研究で明らかになった。同中期になると中部山岳地域ではマメ類の発見例も増大してダイズ属の大型化も確認され、栽培された可能性も言われるようになった。これについてはまだ論ずる段階ではないので触れないが、本研究成果は、縄文時代が定住化とともに初期狩猟・採集段階からマメ類や堅果類の栽培に向けた初期農耕段階にあって、終末期の雑穀栽培を受け入れる社会構造が形成されてきた可能性があり、弥生時代農耕社会へ変革していく動態解明へ大きな成果をもたらすと考えている。
