Building a dinosaur from a chicken: Jack Horner on TED

Posted by: Ben Lillie

Renowned paleontologist Jack Horner has spent his career trying to reconstruct a dinosaur. He’s found fossils with extraordinarily well-preserved blood vessels and soft tissues, but never intact DNA. So, in a new approach, he’s taking living descendants of the dinosaur (chickens) and genetically engineering them to reactivate ancestral traits — including teeth, tails, and even hands — to make a “Chickenosaurus”. (Recorded at TED2011, March 2011, in Long Beach, CA. Duration: 16:37)
