Some animal lineages, such as mammals or trilobites, show particularly high rates of evolution - that is, of species origination and extinction. What makes such lineages special is not clear. A new study shows that, in fossil ammonoid cephalopods, more complex shell ornaments are associated with higher evolutionary rates.
