Evolutionary origins of novel, complex phenotypes are at the heart of Earth's biodiversity. Poison frogs are a model system for the study of complex phenotypes, as the aposematic syndrome, a suite of traits including anti-predator defenses and dazzling coloration, has evolved at least three times within this 310-species clade. The youngest clade of aposematic poison frogs, Epipedobates, is greatly understudied despite its potential to provide insight into origins of chemical defenses and polymorphic warning signals. In this talk I will explore fine-scale variation in these traits and what they can reveal about the evolutionary processes driving the extreme phenotypic diversity we observe in poison frogs and other aposematic organisms.
