Altruism is an uncommon trait in other animals, yet humans regularly show kindness to those they are not closely related to. In evolutionary terms, acting out of concern for a stranger makes no sense. Recent research suggests that rather than the exception to the rule, for humans this type of behaviour is intuitive, reflexive, and even automatic. The predilection to help others seems to be fundamental to who we are, transcending language and culture. To be true to our nature, to be human, means being humane.
