| Outline of Final Research Achievements |
Animals use the sense of taste, olfaction, and vision for selecting the foods in specific environments. We focused on these senses for elucidating the molecular mechanisms underlying in the feeding behaviors of various primates. As results, we found various types of responses in taste receptors as related to their feeding behaviors. The animals use the senses simply or as combination, for the selection of their specific food items.

| Academic Significance and Societal Importance of the Research Achievements |
ヒトを含む霊長類は様々な食性を示すが、その分子メカニズムはあまりよくわかっていませんでした。本研究では、視覚・嗅覚・味覚等の感覚に注目することにより、食物を選択する際にどのような感覚を主に使っているのか記述することに成功しました。例えば、アジアの葉食ザルは苦味や甘味の感覚が減弱していることがわかったため、食べ物を選ぶ際にはこれら以外の感覚を手がかりにしていることが示唆されました。また、中南米のサルの長期観察等により、味覚以外にも視覚や嗅覚を組み合わせて果実等を選んでいることが示されました。ヒトの食物について考える際に、こうした進化的な背景も考慮する必要があるかも知れません。
