From CT scans of 100 lower jaws from African clawed frogs and fire salamanders, we answer the question of whether the amphibian lower jaw evolves as a single unit or evolves with different modules evolving in different ways.
In order to observe the precise morphology of the head bones, we use a micro-computed tomography (micro-CT scanner). This is a 3D imaging technique using x-rays to see inside an object, slice by slice. For our project, we need to…
