Birds of a Feather (USC Research, 2002/10/30)
|Scientists from the Keck School of Medicine of USC for the first time have shown experimentally the steps in the origin and development of feathers, using the techniques of molecular biology.|
Their findings will have implications for the study of the morphogenesis of various epithelial organs – from hairs to lung tissue to mammary glands – and is already shedding light on the controversy over the evolution of dinosaur scales into avian feathers.
