Through the eyes of a wolf: Using non-invasive methods to quantify and classify the facial signalling of wolves (Canis lupus) and domestic dogs (Canis lupus familiaris). Masters thesis, Durham University, UK. ... : The morphologies of wild animals typically evolved via natural selection as a result of environmental pressures leading to specific adaptations to cope with life-history challenges, such as foraging, mating and communication. However, many animals, in particular mammals, have been domesticated by humans. As a result of domestication a range of divergent morphological traits are frequently seen in domesticated mammals that separate them from their wild, ancestral counterparts. Many of these diverged traits pertain to cranium morphologies, such as different head shapes and sizes, shorter muzzles, and different ear shapes and positions. To date, there is little research into the potential implications that these diverged morphological traits of domesticated mammals may pose for their behaviour. A model example of diverged cranium morphologies is seen in the domestic dog, the selectively bred descendant of wolves. It is thought that the head and facial feature morphologies of wolves aid the production of facial ...
