生物形態の多様化機構の一端を解明する目的で,前口動物の付属肢に生じる新奇形質の形成について解析を行なった.原始的昆虫類および環形動物ゴカイ類を用いた解析の結果,前口動物の付属肢の基部背側にはwingless遺伝子が再発現することで新たな器官を作り出す機構が進化的に保存されており,昆虫類では,その器官形成機構に加え,背板に既存する伸展機構が組合わさったことによって,新奇形質のひとつである翅が急速に生じた可能性を見出した.

To understand one end of the diverse mechanism of biomorphology, the analysis of the formation of novel features in the limbs of prostomata is carried out. As a result of the analysis of the use of primitive insect species, the wingless offspring of prostomata on the dorsal side of the base of the limbs have been rediscovered, and new organs have been evolved. The preservation of the organ formation mechanism in insects has been improved, and the existing extension mechanism in the dorsal plate has been combined. The possibility of rapid wing formation of novel forms has been revealed.
