Asymmetry in a pterobranch hemichordate and the evolution of left-right patterning.
To investigate the possible origin of vertebrate asymmetry, we reexamined the long-described asymmetry of pterobranch hemichordates, a group of tiny, mostly colonial marine filter feeders. As first described over a century ago, we found left-right (LR) asymmetry in localization of the gonad. However...
