Understanding the causes of the morphological diversity among organisms is a topic of
great interest to evolutionary developmental biologists. Although developmental biologists …

Reproductive organs are among the most variable and rapidly evolving structures in the
animal kingdom, probably due to sexual selection. In insects, the diverse morphology of …

The emergence and diversification of morphological novelties is a major feature of animal
evolution. 1, 2, 3, 4, 5, 6, 7, 8, 9 However, relatively little is known about the genetic basis of …

Herbivorous insects are extraordinarily diverse, yet are found in only one-third of insect
orders. This skew may result from barriers to plant colonization, coupled with phylogenetic …

Insect male genitalia are among the fastest evolving structures of animals. Studying these
changes among closely related species represents a powerful approach to dissect …

Extensive research in evolutionary biology has focused on the exaggeration of sexual traits;
however, the developmental basis of exaggerated sexual traits has only been determined in …

Adaptive introgression is ubiquitous in animals, but experimental support for its role in
driving speciation remains scarce. In the absence of conscious selection, admixed …

How complex morphologies evolve is one of the central questions in evolutionary biology.
Observing the morphogenetic events that occur during development provides a unique …

Drosophila genitalia and legs are considered to be serially homologous appendages
derived from a ventral appendage'ground state'shaped by different Hox inputs. Despite their …

The genitalia present some of the most rapidly evolving anatomical structures in the animal
kingdom, possessing a variety of parts that can distinguish recently diverged species. In the …
