Homology and Potential Cellular and Molecular Mechanisms for the Development of Unique Feather Morphologies in Early Birds
At least two lineages of Mesozoic birds are known to have possessed a distinct feather morphotype for which there is no neornithine (modern) equivalent. The early stepwise evolution of apparently modern feathers occurred within Maniraptora, basal to the avian transition, with asymmetrical pennaceous...
