One Planet, One People: Beyond "Us vs. Them"

"In this succinct, highly readable overview of the evolution of human society, the author argues that the 21st century will witness a crucially important and difficult transition for the human race. Blending the disciplines of anthropology and evolutionary psychology with over thirty years of experience in the diplomatic corps, Coon traces the evolution of the human tendency to divide others into two groups, "us versus them." People tend instinctively to behave altruistically toward members of their own in-group, and to react with suspicion, or even hostility, toward outsiders.
