over long periods of evolutionary time.12.2 Development of Insect WingsOf the contending hypotheses put forward regarding wing origins, the most influential in driving relevant research have been renditions of. the paranotal (Crampton 1916), gill/exite, and ‘epipodite’ theories. The former hypothesis, in the strict sense, regards w.

The evolution of wings and the adaptive advantage they provide have allowed insects to become one of the most evolutionarily successful groups on earth. The incredible diversity of their shape, size, and color patterns is a direct reflection of the important role wings have played in the radiation of insects. In this review, we highlight ...
Jan 1, 2013 · Insect wings are the most common source of data in palaeoentomology owing to their solidity and resistance to subsequent transportation and taphonomic processes. Generally, insect wings should be considered in conjunction with the remainder of the body for a reconstruction of the entire animal and comprehensive taxonomic and morphological ...

See Box 1 for insect anatomy) [10 ]. The tergal origin hypothesis (a.k.a. paranotal hypothe-sis) proposes that wings evolved from lateral extensions of the thoracic tergum, allowing ancient insects to glide and, when eventually articulated, to fly (blue in Figure 1) [11–13]. The pleural origin hypothesis has many variations, but essentially ...
Aug 8, 2022 · There were two main theories suggesting that wings either evolved from paranota (lateral extensions of the dorsal part of thoracic segments) or tracheal gills. It was hypothesised that the ancestral winged-insect (protopterygote) had three pairs of hinged, veined, thoracic lobes and the mid- and hind-lobes (on the meso- and metathorax ...

The mid- and hind-thoracic lobes are starting to evolve into wings. hinged, veined, thoracic lobes and the mid- and hind-lobes (on the meso- and metathorax) subsequently evolved into fully articulated wings1. Further evidence from the nymphs of Palaeodictyoptera, a group of primitive, extinct, winged insects2, revealed that neither theories ...
