Fig. 3From: Charting Evolution’s Trajectory: Using Molluscan Eye Diversity to Understand Parallel and Convergent EvolutionDifferent evolutionary trajectories seen in convergent and parallel evolution. a In convergent evolution, ancestral phenotypes (A 0 and B 0 ) are unalike but reach a similar endpoint in the descendent taxa (A and B). b In parallel evolution, ancestral phenotypes (C 0 and D 0 ) are similar and evolve in trajectories towards similar endpoints in the descendents (C and D)Back to article page
