Abstract

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 non-flying (apterygote) to flying (pterygote) insects due to the large gap in the fossil record. Under such situation, ontogenic information has historically been used to compensate 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 pleuron and the medial bona fide tergum, to wing evolution. In parallel, recent analyses of Paleozoic fossils have confirmed thoracic and abdominal lateral body outgrowths as transitional wing precursors, and suggest their possible role as respiratory organs in aquatic or semiaquatic environments. These recent studies have revised our understanding of the transition to flying insects. This review highlights recent progress in both evo-devo and paleontology, and discusses future challenges, including the evolution of metamorphic development.

向飞虫的转变：从进化和化石中得到的教训。

昆虫是唯一实现动力飞行的节肢动物，这有助于它们在陆地上产生爆炸性的辐射。由于化石记录的巨大空白，了解从非飞行昆虫（翼虫）到飞行昆虫（翼虫）的进化转变仍然是一个重大挑战。在这种情况下，个体成因信息历来被用来弥补化石证据。最近的进化研究支持并完善了一个基于古生物学的经典假设，即一个祖先的出口合并到体壁中，有助于昆虫翅膀的起源。现代假说定位了祖先的前叶腿段，在六足动物的外侧三节中有一个出口，重新定义了关于昆虫翅膀起源的长期争论。目前的焦点是合并的出口同源物和周围组织，如胸膜和内侧真核，对翅膀进化的贡献。与此同时，最近对古生代化石的分析也证实了胸腹侧体的生长是过渡翼的前体，并表明它们在水生或半水生环境中可能是呼吸器官。这些最近的研究改变了我们对昆虫向飞行昆虫过渡的理解。本文综述了演化-devo和古生物学的最新进展，并讨论了未来的挑战，包括变质发育的演变。

期刊介绍： Current Opinion in Insect Science is a new systematic review journal that aims to provide specialists with a unique and educational platform to keep up–to–date with the expanding volume of information published in the field of Insect Science. As this is such a broad discipline, we have determined themed sections each of which is reviewed once a year. The following 11 areas are covered by Current Opinion in Insect Science. -Ecology -Insect genomics -Global Change Biology -Molecular Physiology (Including Immunity) -Pests and Resistance -Parasites, Parasitoids and Biological Control -Behavioural Ecology -Development and Regulation -Social Insects -Neuroscience -Vectors and Medical and Veterinary Entomology There is also a section that changes every year to reflect hot topics in the field. Section Editors, who are major authorities in their area, are appointed by the Editors of the journal. They divide their section into a number of topics, ensuring that the field is comprehensively covered and that all issues of current importance are emphasized. Section Editors commission articles from leading scientists on each topic that they have selected and the commissioned authors write short review articles in which they present recent developments in their subject, emphasizing the aspects that, in their opinion, are most important. In addition, they provide short annotations to the papers that they consider to be most interesting from all those published in their topic over the previous year.
