Many animal species express, perceive and share emotions. These abilities have been favoured by natural selection because they allow subjects to respond to various situations in an appropriate way, thus facilitating survival and increasing fitness. The same-face/same-emotion phenomenon is at the basis of sharing feelings and emotions. Recent studies show that this capacity is not unique to humans and that it plays an important role in creating cohesive societies in many different species.
