Body plans, which characterize the anatomical organization of animal groups of high taxonomic rank, often evolve by the reduction or loss of appendages (limbs in vertebrates and legs and wings in insects, for example). In contrast, the addition of new features is extremely rare and is thought to be heavily constrained, although the nature of the constraints remains elusive. Here we show that the treehopper (Membracidae) ‘helmet’ is actually an appendage, a wing serial homologue on the first… Expand
Co-option of wing-patterning genes underlies the evolution of the treehopper helmet
TLDR
Comparison of body-region transcriptomes in a treehopper and a leafhopper supports co-option of the wing-patterning network for the origin of the helmet, suggesting that serial homologues may diverge evolutionarily through replacement of, rather than tinkering with, their ancestrally shared patterning network.

Wing serial homologues and the diversification of insect outgrowths: insights from the pupae of scarab beetles
TLDR
The findings suggest that the morphological and underlying gene regulatory diversification of wing serial homologues across species, life stages and segments has contributed significantly to the extraordinary diversity of arthropod appendages and outgrowths. Expand
Insect Morphological Diversification Through the Modification of Wing Serial Homologs
TLDR
Gene expression and functional analyses revealed central roles for the key wing selector genes, vestigial and scalloped, in the hypomeron and the denticular outgrowth formation in the mealworm beetle Tenebrio molitor, suggesting modification rather than loss of dorsal appendages has provided an additional diversifying mechanism for the insect body plan.

Evolutionary biology: The origins of novelty
TLDR
The helmet of treehoppers is classically described as a cuticular expansion of the first thoracic segment, but closer examination now shows that, in evolutionary terms, it corresponds to a third pair of wings. Expand
Divergent role of the Hox gene Antennapedia in spiders is responsible for the convergent evolution of abdominal limb repression
TLDR
It is shown that, unlike Antp in insects, the Antp gene in the spider Achaearanea tepidariorum represses legs in the first segment of the abdomen (opisthosoma), and that Antp and Ubx are redundant in the following segment. Expand
Insights into insect wing origin provided by functional analysis of vestigial in the red flour beetle, Tribolium castaneum
TLDR
It is shown that there are two separate wing serial homologs in the wingless first thoracic segment of a beetle, Tribolium, and these two tissues are merged to form an ectopic wing structure in homeotic transformation, supporting the dual origin of insect wings. Expand
Insect Wings: The Evolutionary Development of Nature’s First Flyers
TLDR
Powered flight has evolved independently at least four times, three of which occur among the Amniota, while the last is far flung across the branches of the animal tree of life. Expand
On Dorsal Prothoracic Appendages in Treehoppers (Hemiptera: Membracidae) and the Nature of Morphological Evidence
TLDR
It is concluded that there is no dorsal, articulated appendage on the membracid T1, and the presence of this structure in Membracidae is not an evolutionary novelty for this clade. Expand
Evolution of thorax architecture in ant castes highlights trade-off between flight and ground behaviors
TLDR
The results reveal that ants invest in the relative size of thorax segments according to their tasks, revealing versatility of head movements allows for better manipulation of food and objects, which arguably contributed to the ants’ ecological and evolutionary success. Expand
Conservation and variation in Hox genes: how insect models pioneered the evo-devo field.
TLDR
The field of evo-devo and Hox genes is introduced, functional tools available to study early developmental genes in insects are discussed, and examples in which changes in H Cox genes have contributed to changes in body plan or morphology are provided. Expand

Probing the evolution of appendage specialization by Hox gene misexpression in an emerging model crustacean
TLDR
The findings suggest a path for the gradual evolutionary transition from thoracic legs to maxillipeds, in which stepwise changes in Hox gene expression have brought about this striking morphological and functional transformation. Expand
Evolution of the insect body plan as revealed by the Sex combs reduced expression pattern.
TLDR
Mapping both gene expression patterns and morphological characters onto the insect phylogenetic tree demonstrates that in the cases of wing suppression and comb formation the appearance of expression of Scr in the prothorax apparently precedes these specific functions. Expand
Homeotic genes and the regulation and evolution of insect wing number
TLDR
It is suggested here that wings first arose without any homeotic gene involvement in an ancestor with a homeotic 'groundplan' similar to modern winged insects and that wing formation subsequently fell under the negative control of individual homeotic genes at different stages of pterygote evolution.

Evolutionary origin of insect wings from ancestral gills
Two hypotheses have been proposed for the origin of insect wings. One holds that wings evolved by modification of limb branches that were already present in multibranched ancestral appendages andExpand

The roles of developmental regulatory genes in the evolution of arthropod morphology are reviewed, with an emphasis on what is known from morphologically diverse species. Expand
Developmental basis of limblessness and axial patterning in snakes
TLDR
It is shown that Hox gene expression domains are expanded along the body axis in python embryos, and that this can account for both the absence of forelimbs and the expansion of thoracic identity in the axial skeleton. Expand
Ultrabithorax is required for membranous wing identity in the beetle Tribolium castaneum
TLDR
It is shown that in this beetle Ubx ‘de-specializes’ the hindwings, which are transformed to elytra when the gene is knocked down, and this counteracting effect of Ubx represents a previously unknown mode of wing diversification in insects. Expand
Changes in Hox genes’ structure and function during the evolution of the squamate body plan
TLDR
The genomic organization of Hox clusters in different reptiles and show that squamates have accumulated unusually large numbers of transposable elements at these loci, reflecting extensive genomic rearrangements of coding and non-coding regulatory regions. Expand
Origin and evolution of insect wings and their relation to metamorphosis, as documented by the fossil record
TLDR
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.

Conservation, innovation, and the evolution of horned beetle diversity
TLDR
The results lend further support to the hypothesis that the origin of beetle horns relied, at least in part, on the redeployment of already existing developmental mechanisms, such as appendage patterning processes and that changes in the exact location and domain size of Dll expression may represent important modifier mechanisms that modulate horn expression in different species or sexes.
