Animals from elephants to crows demonstrate grief behaviors that suggest awareness of death and loss.
Evidence for animal grief and awareness of death challenges assumptions that complex emotional responses to loss are uniquely human. Elephants exhibit prolonged contact with the remains of deceased relatives. Chimpanzee mothers carry dead infants in ways that parallel human bereavement. The acute distress vocalizations of cows separated from calves reflect something beyond mere confusion. Recognizing the capacity for grief in animals strengthens the ethical case for preventing unnecessary deaths and separations.
