Outline of Research at the Start

本プロジェクトでは、強力なアルゴリズムを駆使して、テトラヒメナ・ミツバチ・ヒメアリなどの生命・非生命集団のダイナミクスとその集団現象を研究する。特に2つの観点から明らかにする。一つは、実際の生物実験から得られた個体トラッキングの大量データを解析し、集団運動における創発現象、特に超個体と呼ばれるマクロな創発現象に関する新しい理論を構築する。もうひとつは、大規模な計算機実験により、集団の数が巨大になった(数百万スケールになった)ときの集団運動の解析する。最終目標として、集団の老化(あるいは元気さ)と個体の振る舞いとの関係について議論し、理論的な考察を深めることを目的とする。

Outline of Final Research Achievements

We were able to proceed as planned with the experiments on three biological populations. The results were presented at the SWARM-AROB International Conference (1/25-27/2023). Additionally, on November 22, 2022, at OIST (Okinawa Institute of Science and Technology), we organized a research symposium titled “Collective Intelligence in Living/Non-Living Populations,” featuring guest speakers (Mizumoto/OIST, Shimada/Tokyo University, Kogushi/Institute of Statistical Mathematics, Kashiwagi/Hirosaki University) and engaged in active discussions.

Academic Significance and Societal Importance of the Research Achievements

テトラヒメナの集団における表現型のゆらぎを、世界で初めて定量的に報告した。セイヨウミツバチの役割分化の進化を世界で初めて報告した。またアミメアリがある集団サイズで見せる「個体が擬似的に停止した」クラスターと探索個体への分化を、世界で初めて解析報告した。これらの成果は、集団における「個性の進化」という認識を創り出し、新しく基盤Aを申請するきっかけとなった。
社会的な意義として、個人の才能が先か、いいコミュニティーを見つけるのが先か、という観点をメッセージとして社会に提案することができたことは大きいと思う。
