European mouflon be divided into contact and warning calls and wailing, as well as the mating calls of the rutting ram. Just a few minutes after the birth of a lamb, the ewe utters a short, sombre, bleating noise, to which the lamb replies, also bleating. In the herd, the sheep call for their lambs using a long drawn-out bleating. Lambs who are looking for their mothers bleat loudly, almost blaring. Wailing is heard from the lambs when they are attacked by an enemy or are severely injured. No wailing sound is made by adult mouflon. When alarmed, mouflon emit a hiss
Domesticated red fox humans. Russian scientists achieved a population of domesticated foxes that are fundamentally different in temperament and behavior from their wild forebears. Some important changes in physiology and morphology became visible, such as mottled or spotted colored fur. Some scientists believe that these changes obtained from selection for tameness are caused by lower adrenaline production in the new population, causing physiological changes within relatively few generations yielding genetic combinations not present in the original species. This indicates that selection for tameness, e.g. did not flee, produces changes that are related to the emergence of other dog-like traits, e.g. raised tail, coming
