Beetle horns are attractive models for studying the evolution of novel traits, as they display
diverse shapes, sizes, and numbers among closely related species within the family …

Many scarab beetles produce rigid projections from the body called horns. The exaggerated
sizes of these structures and the staggering diversity of their forms have impressed …

Background The origin of novel traits and their subsequent diversification represent central
themes in evo-devo and evolutionary ecology. Here we explore the genetic and genomic …

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 …

How ecological, developmental and genetic mechanisms interact in the genesis and
subsequent diversification of morphological novelties is unknown for the vast majority of …

An ongoing challenge to evolutionary developmental biology is to understand how
developmental evolution on the level of populations and closely related species relates to …

Beetle horns are enlarged outgrowths of the head or thorax that are used as weapons in
contests over access to mates. Horn development is typically confined to males (sexual …

The origins of novel complex phenotypes represent one of the most fundamental, yet largely
unresolved, issues in evolutionary biology. Here we explore the developmental genetic …

Beetle horns represent an evolutionary novelty exhibiting remarkable diversity above and
below the species level. Here, we show that four typical appendage patterning genes …

Many important questions in developmental biology increasingly interface with related
questions in other biological disciplines such as evolutionary biology and ecology. In this …
