One central developmental change — in a temporary clump of cells called the neural crest — may be behind the suite of characteristics known as domestication syndrome.

Because neural crest cells contribute to so many tissues in the body, altering their function could change an animal's behavior, appearance and biology, the researchers reasoned.

Scientists have long known that the functional neural architecture for perception and cognition strongly depends upon plasticity: in other words, our brain has the capacity to change and adapt as a result of experience.
