We thought mobile beaks were a modern invention but new fossils overturn this idea. Just when did birds first develop their modern mobile beaks? Wild jungle fowl were domesticated to become the chickens we love today. But wild chickens are not isolated completely from modern ones. Gene transfers between wild and domesticated chickens are eroding the genetic diversity of the species.
