What is it about?
Domesticated animals tend to develop many shared traits, such as increased reproduction, reduced stress sensitivity and different growth patterns. Our results suggest that in chickens, such traits may be a result of correlated responses to the inevitable selection for reduced fear of humans occurring early during domestication history.
