Domesticated chickens have smaller brains

(Link ö ping University) Researchers from Link ö ping University suggest a process by which the timid junglefowl from the rain forest could have become today's domesticated chicken. When the scientists selectively bred the junglefowl with least fear of humans for 10 generations, the offspring acquired smaller brains and found it easier to become accustomed to frightening but non-hazardous events. The results shed new light over how domestication may have changed animals so much in a relatively short time.
