Outline of Final Research Achievements

Animals have various color patterns on their body surfaces. There are two types of pattern variations: "close+dissimilar" and "distant+similar." In addition, there are two types of "painting methods" for animal color patterns: "coloring book mode" and "turf war mode." By using comparative analyses focusing on these differences, we revealed some aspects of the developmental and evolutionary mechanisms underlying the diversity of animal color patterns.

Academic Significance and Societal Importance of the Research Achievements

動物体表の模様パターンは、同種識別、交配選択、擬態・隠蔽等、適応的にも大きな意義をもつと考えられる形質です。しかしながら、これまでその形成メカニズムや進化プロセスについては、一部のモデル動物などを除き多くが未解明のままでした。本研究の成果により、複雑な模様パターンが形成されるメカニズムや進化プロセス、パターン形成に関わる候補遺伝子などについて新たな知見が得られ、動物の模様パターンの多様性を生み出すしくみについての理解が深まりました。
