What a big brain we have for all the small talk we make. It's an evolutionary riddle that at long last makes sense in this intriguing book about what gossip has done for our talkative species. Psychologist Robin Dunbar looks at gossip as an instrument of social order and cohesion--much like the endless grooming with which our primate cousins tend to their social relationships.
Apes and monkeys, humanity's closest kin, differ from other animals in the intensity of these relationships. All their grooming is not so much about hygiene as it is about cementing bonds, making friends, and influencing fellow primates. But for early humans, grooming as a way to social success posed a problem: given their large social groups of 150 or so, our earliest ancestors would have had to spend almost half their time grooming one another--an impossible burden. What Dunbar suggests--and his research, whether in the realm of primatology or in that of gossip, confirms--is that humans developed language to serve the same purpose, but far more efficiently. It seems there is nothing idle about chatter, which holds together a diverse, dynamic group--whether of hunter-gatherers, soldiers, or workmates.
Anthropologists have long assumed that language developed in relationships among males during activities such as hunting. Dunbar's original and extremely interesting studies suggest otherwise: that language in fact evolved in response to our need to keep up to date with friends and family. We needed conversation to stay in touch, and we still need it in ways that will not be satisfied by teleconferencing, email, or any other communication technology. As Dunbar shows, the impersonal world of cyberspace will not fulfill our primordial need for face-to-face contact.
From the nit-picking of chimpanzees to our chats at coffee break, from neuroscience to paleoanthropology, Grooming, Gossip, and the Evolution of Language offers a provocative view of what makes us human, what holds us together, and what sets us apart.
Why is it that among all the primates, only humans have language? According to Professor Robin Dunbar's new book,
Grooming, Gossip, and the Evolution of Language, humans gossip because we don't groom each other. Dunbar builds his argument in a lively discussion that touches on such varied topics as the behavior of gelada baboons, Darwin's theory of evolution, computer-generated poetry, and the significance of brain size. He begins with the social organization of the great apes. These animals live in small groups and maintain social cohesion through almost constant grooming activities. Grooming is a way to forge alliances, establish hierarchy, offer comfort, or make apology. Once a population expands beyond a certain number, however, it becomes impossible for each member to maintain constant physical contact with every other member of the group. Considering the large groups in which human beings have found it necessary to live, Dunbar posits that we developed language as a substitute for physical intimacy.
Whether or not you accept Dunbar's premise, his book is worth reading, if only for its animated prose and wealth of scientific information. An obvious choice for science buffs, Grooming, Gossip, and the Evolution of Language is a wonderful book for anyone with an inquiring mind and an interest in what makes the world go round.
