The processes driving biodiversity are legion. I use the tree of life as a backbone to test hypotheses about how variation in form and function arises. Recent work includes the evolution of the eyespot developmental network (Oliver et al. 2012), signaling in caterpillar-ant interactions (Oliver & Stein 2011), and sexual dimorphism in butterflies (Oliver & Monteiro 2011).
