Experts in psychology and strategic leadership reveal how to build teams that really work.

How many people does the ideal team contain? How do groups bond, earn trust and forge shared identities? How can leaders build environments adaptable enough to respond to shocks and still enable people to thrive together? How can you feel close to people if your only point of contact is a phone or a computer?

In The Social Brain leading experts from the worlds of evolutionary psychology and business management come together to offer a primer on great team working. They explain what size groups work and how to shape them according to the nature of the task at hand. They offer practical hints on how to diffuse tensions and encourage cooperation. And they demonstrate the vital importance of balancing unity and the need for different views and outlooks.

By explaining precisely how the 'social brain' works, they show how human groups function and how to create great, high-performing teams.

Dunbar’s Number, as the limit on the size of both social groups and personal social networks, has achieved something close to iconic status and is one of the most influential concepts to have emerged out of anthropology in the last quarter century. It is widely cited throughout the social sciences,archaeology, psychology and network science,and its reverberations have been felt as far afield as the worlds of business organization and social-networking sites, whose design it has come to underpin.Named after its originator, Robin Dunbar, whose career has spanned biological anthropology, zoology and evolutionary psychology, it stands testament to the importance of an interdisciplinary approach to human behaviour. In this collection Dunbar joins authors from a wide range of disciplines to explore Dunbar’s Number’s conceptual origins, as well as the evidence supporting it, and to reflect on its wider implications in archaeology, social anthropology and medicine.

When and how did the brains of our hominin ancestors become human minds? When and why did our capacity for language or art, music and dance evolve? It is the contention of this pathbreaking and provocative book that it was the need for early humans to live in ever-larger social groups, and to maintain social relations over ever-greater distances - the ability to `think big' - that drove the enlargement of the human brain and the development of the human mind. This `social brain hypothesis', put forward by evolutionary psychologists such as Robin Dunbar, one of the authors of this book, can be tested against archaeological and fossil evidence, as archaeologists Clive Gamble and John Gowlett show in the second part of Thinking Big. Along the way, the three authors touch on subjects as diverse and diverting as the switch from finger-tip grooming to vocal grooming or the crucial importance of making fire for the lengthening of the social day. As this remarkable book shows, it seems we still inhabit social worlds that originated deep in our evolutionary past - by the fireside, in the hunt and on the grasslands of Africa.

A fascinating analysis of the evolution of religion from the internationally renowned evolutionary psychologist When did humans develop spiritual thought? What is religion's evolutionary purpose? And in our increasingly secular world, why has it endured? Every society in the history of humanity has lived with religion. In How Religion Evolved, evolutionary psychologist Professor Robin Dunbar tracks its origins back to what he terms the 'mystical stance' - the aspect of human psychology that predisposes us to believe in a transcendent world, and which makes an encounter with the spiritual possible. As he explores world religions and their many derivatives, as well as religions of experience practised by hunter-gatherer societies since time immemorial, Dunbar argues that this instinct is not a peculiar human quirk, an aberration on our otherwise efficient evolutionary journey. Rather, religion confers an advantage: it can benefit our individual health and wellbeing, but, more importantly, it fosters social bonding at large scale, helping hold fractious societies together. Dunbar suggests these dimensions might provide the basis for an overarching theory for why and how humans are religious, and so help unify the myriad strands that currently populate this field. Drawing on path-breaking research, clinical case studies and fieldwork from around the globe, as well as stories of charismatic cult leaders, mysterious sects and lost faiths, How Religion Evolved offers a fascinating and far-reaching analysis of this quintessentially human impulse - to believe.

'Fascinating...In essence, the number and quality of our friendships may have a bigger influence on our happiness, health and mortality risk than anything else in life save for giving up smoking' Guardian, Book of the Day Friends matter to us, and they matter more than we think. The single most surprising fact to emerge out of the medical literature over the last decade or so has been that the number and quality of the friendships we have has a bigger influence on our happiness, health and even mortality risk than anything else except giving up smoking. Robin Dunbar is the world-renowned psychologist and author who famously discovered Dunbar's number: how our capacity for friendship is limited to around 150 people. In Friends, he looks at friendship in the round, at the way different types of friendship and family relationships intersect, or at the complex of psychological and behavioural mechanisms that underpin friendships and make them possible - and just how complicated the business of making and keeping friends actually is. Mixing insights from scientific research with first person experiences and culture, Friends explores and integrates knowledge from disciplines ranging from psychology and anthropology to neuroscience and genetics in a single magical weave that allows us to peer into the incredible complexity of the social world in which we are all so deeply embedded. Working at the coalface of the subject at both research and personal levels, Robin Dunbar has written the definitive book on how and why we are friends.

We are the product of our evolutionary history and this history colours our everyday lives - from why we kiss to how religious we are. In How Many Friends Does One Person Need? Robin Dunbar explains how the distant past underpins our current behaviour, through the groundbreaking experiments that have changed the thinking of evolutionary biologists forever. He explains phenomena such as why 'Dunbar's Number' (150) is the maximum number of acquaintances you can have, why all babies are born premature and the science behind lonely hearts columns. Stimulating, provocative and highly enjoyable, this fascinating book is essential for understanding why humans behave as they do - what it is to be human.

Falling in love is one of the strangest things we can do - and one of the things that makes us uniquely human. But what happens to our brains when our eyes meet across a crowded room? Why do we kiss each other, forget our friends, seek a 'good sense of humour' in Lonely Hearts adverts and try (and fail) to be monogamous? How are our romantic relationships different from our relationships with friends, family or even God? Can science help us, or are we better off turning back to the poets? Basing his arguments on new and experimental scientific research, Robin Dunbar explores the psychology and ethology of romantic love and how our evolutionary programming still affects our behaviour. Fascinating and illuminating, witty and accessible, The Science of Love and Betrayal is essential reading for anyone who's ever wondered why we fall in love and what on earth is going on when we do.

Why do people resort to plastic surgery to look young? Why are stepchildren at greatest risk of fatal abuse? Why do we prefer gossip to algebra? Why must Dogon wives live alone in a dark hut for five days a month? Why are young children good at learning language but not sharing? Over the past decade, psychologists and behavioral ecologists have been finding answers to such seemingly unrelated questions by applying an evolutionary perspective to the study of human behavior and psychology. "Human Evolutionary Psychology" is a comprehensive, balanced, and readable introduction to this burgeoning field. It combines a sophisticated understanding of the basics of evolutionary theory with a solid grasp of empirical case studies.

Covering not only such traditional subjects as kin selection and mate choice, this text also examines more complex understandings of marriage practices and inheritance rules and the way in which individual action influences the structure of societies and aspects of cultural evolution. It critically assesses the value of evolutionary explanations to humans in both modern Western society and traditional preindustrial societies. And it fairly presents debates within the field, identifying areas of compatibility among sometimes competing approaches.

Combining a broad scope with the more in-depth knowledge and sophisticated understanding needed to approach the primary literature, this text is the ideal introduction to the exciting and rapidly expanding study of human evolutionary psychology.

Evolution is one of the most important processes in life. It not only explains the detailed history of life on earth, but its scope also extends into many aspects of our own contemporary behavior-who we are and how we got to be here, our psychology, our cultures-and greatly impacts modern advancements in medicine and conservation biology. Perhaps its most important claim for science is its ability to provide an overarching framework that integrates the many life sciences into a single unified whole. Yet, evolution-evolutionary biology in particular-has been, and continues to be, regarded with suspicion by many. Understanding how and why evolution works, and what it can tell us, is perhaps the single most important contribution to the public perception of science. This book provides an overview of the basic theory and showcases how widely its consequences reverberate across the life sciences, the social sciences and even the humanities. In this book, Robin Dunbar uses examples drawn from plant life, animals and humans to illustrate these processes. Evolutionary science has important advantages. Most of science deals with the microscopic world that we cannot see and invariably have difficulty understanding, but evolution deals with the macro-world in which we live and move. That invariably makes it much easier for the lay audience to appreciate, understand and enjoy. Evolution: What Everyone Needs to Know (R) takes a broad approach to evolution, dealing both with the core theory itself and its impact on different aspects of the world we live in, from the iconic debates of the nineteenth century, to viruses and superbugs, to human evolution and behavior.

The ideas in Robin Dunbar's previous book, Grooming, Gossip and the Evolution of Language, have since become scientific orthodoxy, and this looks set to make an even bigger splash Incredibly influential and popular; all of Dunbar's events for the hardback were sell-outs, and there's much more publicity to come Attractive new cover treatment to appeal to the broad popular science/psychology readership of Robert Winston and Desmond Morris

Alcohol use has a long and ubiquitous history. The prevailing tendency to view alcohol merely as a 'social problem' or the popular notion that alcohol only serves to provide us with a 'hedonic' high, masks its importance in the social fabric of many human societies both past and present. To understand alcohol use, as a complex social practice that has been exploited by humans for thousands of years, requires cross-disciplinary insight from social/cultural anthropologists, archaeologists, historians, psychologists, primatologists, and biologists. This multi-disciplinary volume examines the broad use of alcohol in the human lineage and its wider relationship to social contexts such as feasting, sacred rituals, and social bonding. Alcohol abuse is a small part of a much more complex and social pattern of widespread alcohol use by humans. This alone should prompt us to explore the evolutionary origins of this ancient practice and the socially functional reasons for its continued popularity. The objectives of this volume are: (1) to understand how and why nonhuman primates and other animals use alcohol in the wild, and its relevance to understanding the social consumption of alcohol in humans; (2) to understand the social function of alcohol in human prehistory; (3) to understand the sociocultural significance of alcohol across human societies; and (4) to explore the social functions of alcohol consumption in contemporary society. 'Alcohol in Humans' will be fascinating reading for those in the fields of biology, psychology, anthropology, archaeology, as well as those with a broader interest in addiction.

Robin Dunbar uses economic models to explore the social behavior of the gelada baboon (Theropithecus gelada), a unique species, whose social system is one of the most complex among the primates. His work illustrates the value of an approach that views social behavior as being ultimately concerned with reproduction and with the maximizing of an individual's contribution to its species' gene pool.

To understand who we are and why we are, we need to understand both modern humans and the ancestral stages that brought us to this point. The core to that story has been the role of evolving cognition--the social brain--in mediating the changes in behavior that we see in the archaeological record. This volume brings together two powerful approaches--the social brain hypothesis and the concept of the distributed mind, and compares perspectives on these two approaches from a range of disciplines, including archaeology, psychology, philosophy, sociology and the cognitive and evolutionary sciences.
A particular focus is on the role that material culture plays as a scaffold for distributed cognition, and how almost three million years of artefact and tool uses provides the data for tracing key changes in areas such as language, technology, kinship, music, social networks and the politics of local, everyday interaction in small-world societies. A second focus is on how, during the course of hominin evolution, increasingly large spatially distributed communities created stresses that threatened social cohesion.
This volume offers the possibility of new insights into the evolution of human cognition and social lives that will further our understanding of the relationship between mind and world.

How did we become the linguistic, cultured, and hugely successful apes that we are? Our closest relatives--the other mentally complex and socially skilled primates--offer tantalizing clues. In "Tree of Origin" nine of the world's top primate experts read these clues and compose the most extensive picture to date of what the behavior of monkeys and apes can tell us about our own evolution as a species.

It has been nearly fifteen years since a single volume addressed the issue of human evolution from a primate perspective, and in that time we have witnessed explosive growth in research on the subject. "Tree of Origin" gives us the latest news about bonobos, the "make love not war" apes who behave so dramatically unlike chimpanzees. We learn about the tool traditions and social customs that set each ape community apart. We see how DNA analysis is revolutionizing our understanding of paternity, intergroup migration, and reproductive success. And we confront intriguing discoveries about primate hunting behavior, politics, cognition, diet, and the evolution of language and intelligence that challenge claims of human uniqueness in new and subtle ways.

"Tree of Origin" provides the clearest glimpse yet of the apelike ancestor who left the forest and began the long journey toward modern humanity.

This accessible guide provides an introduction to evolutionary psychology - the fascinating and often controversial new discipline that studies human behavior, evolution and the mind. Starting with its origins in the work of Charles Darwin, the book covers all the key areas of evolutionary psychology, including the role played by genetics in our sexual behavior, parental decision-making, and how babies learn about and adapt to the world. In clear and straight-forward language, the book also breaks new ground in examining the debates and ethical questions raised right now by evolutionary psychology and contemplating their implications for the future of humankind.

Die Entdeckung der Gemeinsamkeit Dieses bemerkenswerte Buch, das die Evolution und die Archaologie des menschlichen Sozialverhaltens zusammenfuhrt, spannt den Bogen von den sozialen Gruppen der Steinzeit bis zu den modernen digitalen Netzwerken - und zeigt, dass wir heute in sozialen Welten leben, die sich tief in unserer evolutionaren Vergangenheit entwickelt haben. Sie werden in diesem Jahr kein wichtigeres Buch lesen. Es koennte uns ein bisschen weiser in unserer Selbsteinschatzung machen. Minerva Ein wunderbares Kompendium von Geschichte, Theorien und faszinierenden Experimenten, das Sie durchweg fesseln wird. BBC Focus In einem Stil geschrieben, der in so bewundernswerter Weise wissenschaftliches Fachvokabular und Soziologenjargon vermeidet, dass man nicht mehr als ein normales menschliches Gehirn braucht, um es zu lesen und zu verstehen ... eine sehr wertvolle Zusammenfassung unseres gegenwartigen Wissens uber die Evolution des Menschen und den moeglichen Ursprung und die Entwicklung [solcher] menschlicher Eigenschaften und Fahigkeiten ... Evolution, Denken, Kultur ist wie der Urknall: wahrscheinlich noch nicht die ganze Antwort, aber zweifellos schon die Erklarung einer grossen Zahl beobachtbarer Phanomene, und fur die Debatte und Weiterentwicklung unserer Vorstellungen uber die Ursprunge und die Evolution der menschlichen Kognition wird es auf Jahrzehnte hinaus als fuhrendes Modell dienen. Society of Antiquaries Newsletter Ein dramatischer Schlag gegen den "Steine und Knochen"-Ansatz der Archaologie. New Scientist Zugleich ein Triumph der Zusammenarbeit und eine packende Detektivgeschichte. New Statesman _____ Wann und wie entwickelte sich das Gehirn unserer fruhen Vorfahren zu einem menschlichen Gehirn? Wann und wie entstand in der Evolution unsere Fahigkeit, zu sprechen und Kunstwerke zu schaffen, zu musizieren und zu tanzen? Die Groesse der sozialen Gruppen, in denen Menschen heute leben - Angehoerige, Freunde, Bekannte -, betragt ungefahr 150 Personen. Diese "Dunbar-Zahl" liegt etwa dreifach hoeher als bei Menschenaffen und unseren altesten Vorfahren. Wie die Autoren dieses bahnbrechenden Buches darlegen, waren die fruhen Menschen im Kampf ums UEberleben gezwungen, sich zu immer groesseren Gruppen zusammenzuschliessen und zwischenmenschliche Beziehungen uber weite Distanzen aufrechtzuerhalten. Sie mussten "im Grossen denken", und dies wiederum trieb sowohl das Wachstum des menschlichen Gehirns als auch die Entstehung des menschlichen Geistes voran. Aus dem gegenseitigen Kraulen der Menschenaffen erwuchs die fur Menschen kennzeichnende sprachliche Zuwendung. Musik und Tanz verstarkten die Bindungen zwischen ihnen. Und die Beherrschung des Feuers verlangerte den Tag fur zwischenmenschliche Aktivitaten. Heute beherrschen soziale Netzwerke die Welt. Doch erstaunlicherweise entspricht die Zahl unserer Facebook- oder Twitter-Kontakte im Mittel der Dunbar-Zahl. Offenbar leben wir immer noch in einer sozialen Welt, die ihre Wurzeln tief in unserer Evolutionsvergangenheit hat - am Lagerfeuer, auf der Jagd und in den Graslandschaften Afrikas.

Other people and their behaviour are a subject of endless fascination for us. Our understanding of why we behave in certain ways can be greatly enhanced if we take an evolutionary perspective. Understanding the evolutionary pressures that have shaped human behaviour can give us a new insight into why we prefer a good gossip to a lengthy session of algebra, or why children are so good at learning language and so poor at sharing nicely with others. Human Evolutionary Psychology offers a comprehensive overview of all aspects of human evolutionary behaviour and psychology. Tackling everything from mate choice to marriage patterns, childcare to cultural evolution, Human Evolutionary Psychology critically assesses the value of evolutionary explanations to humans in both modern western society and traditional pre-industrial societies. The combination of broad scope and in-depth analysis makes it the ideal introduction to this exciting and rapidly expanding area of research.

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.
