A new paper from the lab was published today in the Biological Journal of the Linnean Society focusing on aberrant spinescent phenotypes in Pheidole (including the famous dragon ants). We look at spinescence from a number of angles including phylogenetic, ecological, geographic, and 3D morphology. This study sheds light on the complexity of the issue of spine phenotype evolution. There are a number of open questions and some big mysteries. For starters, why the heck has spinescence evolved so many times in the Indo-Pacific, but no spiny Pheidole in New World?
