The evolutionary transition from reptiles to mammals: analyses of body size reduction and separation of middle ear elements from the jaw
Body size generally decreased during synapsid evolution until the origin of mammals, and this decrease has often been linked to the evolution of mammal-like characteristics. Despite the importance of these patterns to our understanding of mammalian evolution, the particular evolutionary mechanisms …

The influence of developmental patterns on vertebrate evolution, with the evolution of the sacrum and pelvis as a case study
… morphologies along the normally constrained synapsid lineage that are convergent on several archosaurian innovations, integrating comparative anatomy, comparative phylogenetic methods, and developmental biology. The third chapter utilizes a new technique (modified CLARITY protocol) for …
