タイトル: The transition to flying insects: lessons from evo-devo and fossils著者: Ohde, Takahiro; Prokop, Jakub抄録: Insects are the only arthropod group to achieve powered flight, which facilitated their explosive radiation on land. It remains a significant challenge to understand the evolutionary transition from nonflying (apterygote) to flying (pterygote) insects due to the large gap in the fossil record. Under such a situation, ontogenic information has historically been used to compensate for fossil evidence. Recent evo-devo studies support and refine a paleontology-based classical hypothesis that an ancestral exite incorporated into the body wall contributed to the origin of insect wings. The modern hypothesis locates an ancestral precoxa leg segment with an exite within the hexapod lateral tergum, reframing the long-standing debate on the insect wing origin. A current focus is on the contributions of the incorporated exite homolog and surrounding tissues, such as the pl ...
