Outline of Final Research Achievements

Hexapoda (Insecta s. lato), which is known as the most prosperous group in animals, have developed the tough cephalic endoskeletal system named tentorium, that ensures strong biting. An anagenetic transition is demonstrated on the tentorial system, i.e., from Monocondylia (Archaeognatha), via apterous Dicondylia (Zygentoma), to winged Dicondylia (Pterygota), but nothing definite is yet to be clarified on the ancestral states of the hexapod tentorial system. The present study analyzed the morphogenesis of the cephalic endoskeleton in the hexapod basal lineages “Entognatha,” and produced significant results such as: 1) the cephalic endoskeleton of Protura, to which the most ancestral state in hexapods has been bestowed, proved to be the structure autapomorphic to the group, and 2) that of Diplura was demonstrated to represent the most primitive state leading to the tentorial system. We also developed discussions on the hexapod phylogeny, focusing on the basal hexapods and Polyneoptera.

Academic Significance and Societal Importance of the Research Achievements

六脚類(広義の昆虫類)は種数において全動物の75%、全生物の60%を占める、最も多様性の高い動物群、生物群である。したがって、動物を理解する上で、また、生物を考えていく上で、六脚類は最も興味深いグループである。ドブジャンスキーが「進化の光に照らさない生物学は何の意味もなさない」と語ったように、生物を理解するためには、生物、個々のグループの進化が正確にフォローされなければならない。動物を理解する上で、また、生物とは何かを語るために、六脚類は最重要のグループであり、私たちは六脚類の進化を正しく把握したい。本研究は、六脚類の系統進化を、頭部内骨格の進化的変遷との視点から、描写したものである。
