2. May 15,  · 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 biologists for centuries. Recent comparative studies using DNA sequence-based phylogenies have begun to reconstruct the historical patterns of beetle horn evolution. At the same time, developmental .

3. The phylogenetic hypothesis for the Mylagaulidae gives a framework for constraining the timing of cranial horn evolution. Ceratogaulus is the largest known mylagaulid, as indicated by cranial dimensions, and is notably larger than its sister clade, Hesperogaulus.

8. The principal means of evolution of antlers is sexual selection, which operates via two mechanisms: male-to-male competition (behaviorally, physiologically) and female mate choice. Male-male competition can take place in two forms.
