Following Feathers from Birds to Dinosaurs

Developing tail feathers of an embryonic duckling, stained for expression of the gene Sonic Hedgehog (blue). The feathers reveal the role of the interbarb epithelium in the control of barb ridge morphogenesis, helical growth, and barb fusion to form the rachis of the feather.

Richard Prum, a biologist at Yale University and the director of the Yale Peabody Museum of Natural History, is one of the leading experts on the evolution of feathers and the relationship between birds and their dinosaur ancestors Recently, Prum and his colleagues showed that an ancient, 47-million-year-old bird had colored feathers, a first step that may eventually help scientists determine the color of feathers on some dinosaurs. Recently, Prum won a MacArthur Foundation grant to support his research. For more on Prum's work, see the university press release or Prum's website.
