El enjambre humano

One of the characteristics that distinguishes a community of chimpanzees from a human community is that, while a New Yorker can fly to Borneo without fear for his life, a chimpanzee who ventures into foreign territory is in mortal danger. Psychologists have not done much to explain this fundamental difference: for decades they have argued that the limit of a social group is 150 members. However, many more individuals coexist in human society. How is this coexistence possible? Mark W. Moffett breaks our mind-sets from findings in the fields of psychology, sociology, and anthropology and offers us a brilliant explanation of the social adaptations that unite modern communities. In the vein of great editorial phenomena such as Sapiens and Arms, germs and steel, The Human Swarm is a revealing investigation into how human beings have developed extremely complex civilizations.
