Resumen de Adult chimps are less consoling
Adult chimpanzees are less likely than young ones to console companions in times of distress. The finding raises questions about how the capacity for empathy changes with age in people's closest relatives--and them. When a chimpanzee gets upset, companions often sit with them and offer reassurance by kissing, grooming or embracing them. They know chimpanzees have personalities: lasting individual features in their behavior. But it was unclear whether their empathetic tendencies are part of their personality, and whether they change over time. Christine Webb at Emory University in Atlanta, Georgia, and her colleagues studied eight years of observations of a group of 44 chimpanzees at Yerkes National Primate Research Center.
