Knockout of crustacean leg patterning genes suggests that insect wings and body walls evolved from ancient leg segments.
- BiologyNature ecology & evolution
The phenotypes for the knockout of five leg patterning genes in the crustacean Parhyale hawaiensis are reported and these suggest that insect wings are not novel structures, but instead evolved from existing, ancestral structures.

This broad toolkit has the potential to accelerate many traditional areas of cricket research, including studies of adaptation, evolution, neuroethology, physiology, endocrinology, regeneration, and reproductive behavior, and it may also help to establish newer areas, for example, the use of crickets as animal infection model systems and human food sources.

Origin and evolution of insect wings and their relation to metamorphosis, as documented by the fossil record
- BiologyJournal of morphology
All primitive Paleozoic pterygote nymphs are now known to have had articulated, freely movable wings reinforced by tubular veins, which suggests that the wings of early Pterygota were engaged in flapping movements, and that the immobilized, fixed, veinless wing pads of Recentnymphs have resulted from a later adaptation affecting only juveniles.
Origin of the insect wing and wing articulation from the arthropodan leg
The most primitive known pterygote terga, wing articulation, wings, and upper leg segments with exites, occur in gigantic Upper Carboniferous Paleodictyoptera, Homoiopteridae. Fossil features are…

Locomotor performance of insects with rudimentary wings
It is shown that Allocapnia vivipara stoneflies use a non-flying form of aerodynamic locomotion which may exemplify a precursor to flight, and this support the hypothesis that insect wings evolved from articulated gill plates of aquatic ancestors through an intermediate semi-aquatic stage.
The Origin of Wings and Venational Types in Insects
Most insect morphologists now agree that there is a fundamental pattern from which all the insect venations are derived, though there is still a good deal of argument as to the equivalence of particular veins in the different orders.
Selective Factors in the Evolution of Insect Wings
Flight represents a major innovation that has evolved independently in several different animal groups and how such key innovations can evolve has been one of the major questions in evolutionary biology since the time of Darwin.
Rowing locomotion by a stonefly that possesses the ancestral pterygote condition of co-occurring wings and abdominal gills
This work examines the locomotor behaviour and gill morphology of a stonefly, Diamphipnopsis samali (Plecoptera), which retains abdominal gills in the winged adult stage, and suggests an ability to contribute to gas-exchange in an amphibious setting during a transition from aquatic to aerial locomotion and gas exchange.
REANALYSIS AND EXPERIMENTAL EVIDENCE INDICATE THAT THE EARLIEST TRACE FOSSIL OF A WINGED INSECT WAS A SURFACE‐SKIMMING NEOPTERAN
- Geography, Environmental ScienceEvolution; international journal of organic evolution
Results suggest that this fossil best fits a scenario in which a neopteran insect skimmed across the surface of water, then folded its wings, and was a precursor to the evolution of flight in insects.
The surface-skimming hypothesis for the evolution of insect flight
Both the mechanics and the semi-aquatic setting of skimming fit well with the growing understand- ing that insects and crustaceans are sister clades and that insect wings evolved from gills.

Details of one of the important forms of insects, Rhyniognatha hirsti from the famous Rhynie Chert Lagerstätte, are provided with up-to-date 3D imaging techniques and it is pointed out that R.hirsti could be interpreted as an early centipede.
