In an SFI Community Lecture June 27 in Santa Fe, SFI Omidyar Fellow alumnus Dan Hruschka searched for clues in the origins of human friendship – how it develops, how it varies across cultures, and how it compares to social ties in other species.

Friends sacrifice for one another without apparent concern for consequences or reciprocation. Such unconditional acts of selflessness provide an important buffer against hardship, both for individuals and for human societies. But they also pose an evolutionary puzzle. How does humankind benefit from unconditional aid when false friends and exploiters abound?
