Syrinx, hyoid, and larynx character optimisation onto morphology-only, molecular-only, and combined-data topologies. Optimised characters which received a CI value of 0.5 or above are shown on each topology with the derived state in the character change denoted by brackets. Rounded brackets indicate the change was ambiguous whereas square brackets indicate unambiguous state changes. Stars show the state change to be unique and unreversed (CI=1.0) and the bold characters are both unambiguous and unique and unreversed. a Morphological topology optimisation. b Molecular topology optimisation. c Combined-data topology optimisation
