Humans are said to be selfish, and the assertion that greed is good has been followed. But is altruism really an illusion? Though evolutionary theorists have a tendency to focus on competition and the ruthlessness of natural selection, they often find themselves not being able to explain one crucial fact — that humans could not have survived in nature without the charity and social reciprocity of a group.
German researchers have discovered that infants as young as 18 months display altruistic behavior, which suggests that humans have a natural inclination towards being helpful.
