Social structure in elephant herds is surprisingly complex. The adults in the herd exhibit what scientists call "reciprocal altruism." That means that elephants will act in ways that give them no direct benefit—say, protecting or feeding a calf that isn"t theirs. They do that because the other elephants in their herd will do the same for them. Maybe the elephant is a good role model for Giving Tuesday?
