A Mechanism of Extreme Growth and Reliable Signaling in Sexually Selected Ornaments and Weapons
Truthful Embellishments Exaggerated ornaments such as beetle horns, deer antlers, and extreme tail lengths in birds are typically assumed to be subject to sexual selection because they signal theExpand

Exaggerated trait growth in insects.
Animal structures occasionally attain extreme proportions, eclipsing in size the surrounding body parts. We review insect examples of exaggerated traits, such as the mandibles of stag beetlesExpand

A general mechanism for conditional expression of exaggerated sexually‐selected traits
Sexually‐selected exaggerated traits tend to be unusually reliable signals of individual condition, as their expression tends to be more sensitive to nutritional history and physiologicalExpand

Insights into the Development and Evolution of Exaggerated Traits Using De Novo Transcriptomes of Two Species of Horned Scarab Beetles
Scarab beetles exhibit an astonishing variety of rigid exo-skeletal outgrowths, known as “horns”. These traits are often sexually dimorphic and vary dramatically across species in size, shape,Expand

Are entrenched characters developmentally constrained? Creating biramous limbs in an insect
SUMMARY Are evolutionarily entrenched phenotypes highly constrained developmentally? We explored this question in the case of the uniramous appendages of fruit flies. We created bi‐ and polyramousExpand
