報告人介紹：Robert Dudley教授，男，博士，1961年出生于英國，1987年獲劍橋大學博士學位。持英、美雙重國籍護照，現為美國加州大學Berkeley分校終身教授，全面負責Animal Flight Laboratory的工作。Dudley教授主要從事昆蟲飛行機理和飛行流體力學方面的理論和實驗研究，在生物流體力學、昆蟲形態學以及其他相關方面有很深的造詣，在國際著名雜志Science 和Nature 上發表研究論文4篇，在相關領域內各類頂級雜志（如PNAS, Journal of Fluid Mechanics，The Journal of Experimental Biology等 ）上發表研究論文幾十篇，是Science 、Nature以及多本頂級學術雜志的審稿人以及多本頂級學術雜志編委，其專著《The Biomechanics of Insect Flight》（Princeton大學出版社），為本研究領域的最著名的經典著作之一。近3年發表論文學術論文11篇，平均影響因子為4.472.

內容介紹：Diverse animal taxa exhibit remarkable aerial capacities, including jumping, aerial righting, parachuting, gliding, landing, controlled maneuvers, and flapping flight.  The origin of wings in hexapods and in three separate lineages of vertebrates (pterosaurs, bats, and birds) greatly facilitated subsequent lineage diversification, but both the paleobiological context and possible selective pressures for wing evolution remain contentious.  Larvae of various arboreal hemimetabolous insects, as well as many canopy ants, demonstrate the capacity for directed aerial descent in the absence of wings.  Aerial control in the ancestrally wingless archaeognathans also suggests that flight behavior preceded the origins of wings in hexapods.  In evolutionary terms, the use of of winglets and partial wings to effect aerial righting and gliding maneuvers could select for enhanced appendicular motions, and ultimately lead to powered flight.  Flight behaviors that involve neither flapping nor wings are likely much more widespread than is currently recognized.  Further characterization of the sensory and biomechanical mechanisms used by these aerially capable taxa can potentially assist in reconstruction of ancestral winged morphologies and facilitate our understanding of the origins of flight.
