Sharing and the ability to distance oneself from one’s self-interests and inclinations are commonly seen as uniquely human traits. But what does it actually mean to be altruistic, and how has altruism evolved? How is cooperative behavior learned and how does it spread throughout a group? At this event entitled “Sharing and the Evolution of Human Altruism,” the New York-based philosopher Philip Kitcher will examine the terminological foundations of altruism. The primatologist Christophe Boesch and the behavioral biologist Sabine Tebbich will talk about empirical studies with hominids and provide insight into reciprocal altruism in animal communities.
