Yawning is an involuntary respiratory act that scientists believe is characteristic of most vertebrates. Its occurrence can have both physiological causes, such as thermoregulation or sleepiness, and social causes, which are less well understood.

‘To investigate the social causes of yawning, it is interesting to observe it in animals with a certain cognitive complexity that live in cohesive groups, such as primates or marine mammals. This behavioural response in different species may be due to very similar factors,’ stressed study author Professor Clara Lamazares from the University of Valencia.
