CNN - Why we're creating a ‘chickenosaurus’

(excerpt from Jack Horner's Ted talk): "...My colleague Hans Larsson, using developmental biology techniques at McGill University, was studying the transition between extinct dinosaurs and birds, trying to understand how birds came to lose their tails and transform hands to wings. I figured if he could figure this out, we could reverse the methods and make a bird with hands and a tail. It was the beginning of the "Build a Dinosaur Project."
