Shoals, swarms, flocks, herds--group formation is a widespread phenomenon in animal populations. It raises several interesting questions for behavioral ecologists. Why do animals form and live in groups, and what factors influence the ways in which they do this? What are the costs and benefits to an anmimal of group living? How are these influenced by ecological factors?

One of the distinctive features of humans is their unique sociality. Humans live in organized societies that are characterized by a high level of interdependence of group members in various aspects of life, ranging from the economic phenomenon of labour division to providing emotional support to others. Under these circumstances, the capacity to track social connections within and between groups has great adaptive value in managing everyday life. We may understand the importance and adaptive value of tracking the scope of culturally shared knowledge if we consider the importance of cultural norms in guiding behaviour. To become a competent member of their cultural group one must be able to conform to the group's specific behavioural norms and to accumulate culturally shared knowledge. Acquiring this knowledge is essential for successful social interactions. In contrast to current dominant explanatory theories emphasizing that social category formation is simply rooted in humans’ need to belong and affiliate with a group, the aim of this e-book is to provide evidence that, in addition to its affiliative role, children form social categories for epistemic purposes. We show that children use specific cues, like kinship, patterns of resource allocation and consensus to understand group cohesion (Section 1). Once children figured out who is in-group and who is out-group, they show a significant in-group bias in attention, acting and learning (Section 2). Yet, this in-group bias can be attenuated by induced synchronous behavior (Section 3).

Cheetahs of the Serengeti Plains is the most comprehensive account of carnivore social behavior to date. Synthesizing more than a decade of research in the wild, this book offers a detailed account of the behavior and ecology of cheetahs. Compared with other large cats, and other mammals, cheetahs have an unusual breeding system; whereas lions live in prides and tigers are solitary, some cheetahs live in groups while others live by themselves. Tim Caro explores group and solitary living among cheetahs and discovers that the causes of social behavior vary dramatically, even within a single species. Why do cheetah cubs stay with their mother for a full year after weaning? Why do adolescents remain in groups? Why do adult males live in permanent associations with each other? Why do adult females live alone? Through observations on the costs and benefits of group living, Caro offers new insight into the complex behavior of this extraordinary species. For example, contrary to common belief about cooperative hunting in large carnivores, he shows that neither adolescents nor adult males benefit from hunting in groups. With many surprising findings, and through comparisons with other cat species, Caro enriches our understanding of the evolution of social behavior and offers new perspectives on conservation efforts to save this charismatic and endangered carnivore.

Richard D. Alexander is an accomplished entomologist who turned his attention to solving some of the most perplexing problems associated with the evolution of human social systems. Using impeccable Darwinian logic and elaborating, extending and adding to the classic theoretical contributions of pioneers of behavioral and evolutionary ecology like George Williams, William Hamilton and Robert Trivers, Alexander developed the most detailed and comprehensive vision of human social evolution of his era. His ideas and hypotheses have inspired countless biologists, anthropologists, psychologists and other social scientists to explore the evolution of human social behavior in ever greater detail, and many of his seminal ideas have stood the test of time and come to be pillars of our understanding of human social evolution. This volume presents classic papers or chapters by Dr. Alexander, each focused on an important theme from his work. Introductions by Dr. Alexander's former students and colleagues highlight the importance of his work to the field, describe more recent work on the topic, and discuss current issues of contention and interest.

Living in groups has been an animal survival strategy for millions of years. Animal Life in Groups explores the social lives of bees, meerkats, monkeys, and other animals and insects, with a special emphasis on how different groups compare to one another and how living with others benefits individuals. From hives to more complex cultures, the intricacies of community living are both fascinating and instructive about the evolution of behavior, cooperation, intelligence, and emotions.
