Australian bearded dragon (Pogona vitticeps) providing important insights into vertebrate brain evolution, as revealed by the work of Max Planck scientists on the brain of these reptiles. 

Neuroscientists at the Max Planck Institute for Brain Research in Frankfurt generated a molecular atlas of the dragon brain and comparing it with one from mice. Their findings suggest that, contrary to popular belief that a mammalian brain consists of an ancient “reptilian” brain supplemented with new mammalian features, both reptilian and mammalian brains evolved their own clade-specific neuron types and circuits, from a common ancestral set.
