| Outline of Final Research Achievements |
This study tested whether reared boars can be detected by three-dimensional dental microwear. As resluts, the modern wild boars had significantly smooth surface with scratches, whereas those of the stall-fed were dominated by large and deep gouges althogh their genetic backgrounds were almost similar. Dental microwear also differed between the two wild populations with different body sizes and habitats. These results suggest that dental microwear of boar reflects several factors not only dietary contents. For further study, it is necessary to determin which factor is the key of dental microwear prior to fully application this method for zooarchaeological remains.

| Academic Significance and Societal Importance of the Research Achievements |
本研究が提唱する推定法は、所要時間が短く、非破壊的であり、また死亡直前の食性に対する検出力が優れるなど、出土資料の分析に好適である。本手法と他の手法とを同一資料に併用すれば、個体レベルで「ヒトによる飼育」の有無を直接的に確かめられるようになり、飼料を食べ始めた「野生」個体や、再野生化した「家畜」個体など、従来は困難だった事例を検出できる可能性がある。これらの成果を通じて、家畜動物の成立過程と、その伝播に関する詳細な知見を得ることが可能になると期待される。
