The 'Evolution of Cooperation' addresses a simple yet age-old question; If living things evolve through competition, how can cooperation ever emerge? Despite the abundant evidence of cooperation all around us, there existed no purely naturalistic answer to this question until 1979, when Robert Axelrod famously ran a computer tournament featuring a standard game-theory exercise called The Prisoner's Dilemma. To everyone's surprise, the program that won the tournament, named Tit for Tat, was not only the simplest but the most "cooperative" entrant. (...) This unexpected victory proved that cooperation - one might even say altruism - is mathematically possible and therefore needs no hidden hand or divine agent to create and sustain it. A great roadblock to the understanding of all sorts of behavior was at last removed. The updated edition includes an extensive new chapter on cooperation in cancer cells and among terrorist organizations. (shrink)

Bernd Heinrich and Maine ravens are exemplars of Despret's concepts of politeness, “faire connaissance” and recruitment. He was dissuaded by his mentor from studying them due to their intelligence and their recalcitrance against reductive methods. Gaining their confidence would take years. Once he did so they allowed him to see an astonishing range of behaviors and they accepted him as a socius. This was research that took into account the interests of the ravens themselves to answer complicated questions about their (...) behavior. Ravens also practice this intermingling of interests and action with wolves. (shrink)
