This chapter examines the evolution of bird brain, social contact, and birdsong. Communicative capabilities are widespread, whether in song or through other forms of intimate social contact. One mechanism for this is the regulation of information molecules in the brain such as vasopressin and oxytocin. The chapter first provides an overview of information molecules before connecting these processes to song in frogs, crickets, and birds. It then considers neurogenesis and how information molecules work in the human brain, focusing on some core biology underlying animal song and social contact. It shows that steroid hormones facilitate neuropeptide expression in many species, which underlies song tied to the regulation of the internal milieu, territorial expression, reproduction, and a much wider range of social behaviors.Less

Understanding of animal social and sexual evolution has seen a renaissance in recent years with discoveries of frequent infidelity in apparently monogamous species, the importance of sperm competition, active female mate choice, and eusocial behavior in animals outside the traditional social insect groups. Each of these findings has raised new questions, and suggested new answers about the evolution of behavioral interactions among animals. This volume synthesizes recent research on the sexual and social biology of the Crustacea, one of the dominant invertebrate groups on earth. Its staggering diversity includes ecologically important inhabitants of nearly every environment from deep-sea trenches, through headwater streams, to desert soils. The wide range of crustacean phenotypes and environments is accompanied by a comparable diversity of behavioral and social systems, including the elaborate courtship and wildly exaggerated morphologies of fiddler crabs, the mysterious queuing behavior of migrating spiny lobsters, and even eusociality in coral-reef shrimps. This diversity makes crustaceans particularly valuable for exploring the comparative evolution of sexual and social systems. Despite exciting recent advances, however, general recognition of the value of Crustacea as models has lagged behind that of the better studied insects and vertebrates. This book synthesizes the state of the field in crustacean behavior and sociobiology, and places it in a conceptually based, comparative framework that will be valuable to active researchers and students in animal behavior, ecology, and evolutionary biology. It brings together a group of experts in fields related to crustacean behavioral ecology, ranging from physiology and functional morphology, through mating and social behavior, to ecology and phylogeny. Each chapter makes connections to other non-crustacean taxa, and the volume closes with a summary section that synthesizes the contributions, discusses anthropogenic impacts, highlights unanswered questions, and provides a vision for profitable future research.Less

This chapter reviews current knowledge of the neurobiological regulation of affiliative, aggressive, sexual, and parental behavior in nonhuman primates. It focuses on social behavior expressed in the context of interactions between two or more individuals. It begins by reviewing research on the neurochemical control of primate social behavior, particularly studies of endogenous opioids, oxytocin and vasopressin, and the brain monoamine systems. It then considers the results of brain lesion studies investigating the neural substrates of primate social behavior. The chapter concludes by summarizing the main trends emerging from this literature review, and by discussing future research directions.Less

Hans Kruuk's previous Wild Otters was the first, and until now the only, book to cover both natural history and scientific research on behaviour and ecology of otters in Europe. The present book is a revision, rewrite, and update, now covering all species of otter in North America as well as Europe and elsewhere. Aimed at naturalists, scientists, and conservationists, in a personal style and with many illustrations, it describes the ecology and behaviour of some of the most charismatic and enigmatic mammals in our environment, as well as the research to understand their particular ecological problems. With over 650 references, there is up-to-date description of the most recent studies, including feeding ecology, foraging behaviour, relationships with prey species, and factors that limit populations, as well as social and breeding behaviour, molecular genetics, energetics, the problems of exposure to cold water, mortality, effects of pollution, and the serious, recent conservation problems. There are enchanting direct observations of the animals, as well as guidance about how and where to watch and study them, and what are the most serious questions facing researchers. From otters in the British and American lakes and rivers, to sea otters in the Pacific ocean, giant otters in the Amazon and other species in Africa and Asia, this book provides an enthusiastic, critical, and thorough approach to their fascinating existence, the science needed to understand it, and the threats to their survival.Less

This book offers a fundamental new theory of motor cortex organization: the rendering of the movement repertoire onto the cortex. The action repertoire of an animal is highly dimensional, whereas the cortical sheet is two-dimensional. Rendering the action space onto the cortex therefore results in a complex pattern, explaining the otherwise inexplicable details of motor cortex organization. This book includes a complete history of motor cortex research from its discovery to the present, a discussion of the major issues in motor cortex research, and an account of recent experiments that led to the book's “action map” view. Though focused on motor cortex, the book includes a range of topics from an explanation of how primates put food in their mouths, to the origins of social behavior such as smiling and laughing, to the mysterious link between movement disorders and autism.Less

As the author states at the outset of this chapter, the study of nonverbal communication is noncontroversially the study of social behavior, as nonverbal communication usually involves the expression and interpretation of nonverbal behaviors and subsequent responses to those behaviors. The study of nonverbal communication generally follows one of two main research traditions. The first tradition involves the description of nonverbal behavior, with the research goal of attempting to understand the antecedents, consequences, and sometimes the correlates of that behavior. The second research tradition involves the study of nonverbal communication skills in expression (encoding) and judgment (decoding), with the research goals of being able to differentiate skill levels, and to understand other person and situation correlates of skill level. The author also explores the good, the bad, and the ugly of nonverbal communication research, in an attempt to demonstrate the possibilities and utilities of a focus on actual social behavior.Less

This chapter provides a comparative background for the study of dog behaviour by introducing the main behavioural features of dog-like species of Canis. The main aim here is to give an understanding of evolutionary and ecological constraints that might have played an important role in shaping the behaviour of this group of predators. Most emphasis is given to the behaviour of the wolf, which is considered to be the ancestor of all dogs living today. A detailed review of the social aspects of wolf behaviour offers also a comparison to the similar traits in feral dogs.Less

This chapter considers a simple and general model of natural selection: replicator dynamics. Many animal traits and behaviors are social, in that they affect the reproductive success not just of the animal performing the behavior, but also conspecifics. Mathematical theories based on classical natural selection, which acts on direct reproduction by individuals, are able to explain the evolution of traits that are for personal advantage. However, this leaves the problem of providing an evolutionary explanation of traits and social behaviors that appear to be personally costly to the bearer, in reproductive terms, while having effects on conspecifics such as increasing their direct reproduction. This chapter uses the replicator dynamics to illustrate the action of natural selection on social behavior, including nonadditive interactions. It considers the additive and nonadditive donation game, and other social interactions, along with public goods games, threshold public goods games, and interactions in structured populations.Less

This chapter examines which of the equivalent alternative partitions of fitness, including inclusive fitness and group fitness, can be interpreted as being subject to natural selection in a meaningful way. Inclusive fitness theory can deal with subtleties such as nonadditive fitness effects and conditionally expressed phenotypes. However, selection based on inclusive fitness gives equivalent predictions to other models of apparently different evolutionary processes, such as multilevel selection. The chapter considers how we can determine whether inclusive fitness really captures the essence of social evolution and whether inclusive fitness is really maximized by the action of selection, as suggested by William D. Hamilton. It also explains what heritability measures, and whether this makes sense biologically. Finally, it discusses the problem of classifying observed social behaviors in terms of their underlying evolutionary explanations.Less

This chapter describes the intragroup social behaviour of red colobus, including grooming, reproduction, aggression, and miscellaneous behaviour. Most of the information comes from the detailed and long-term studies of two social groups of tephrosceles in Kibale. Results from the Kibale studies are compared with the only other taxa for which there are details on these topics, i.e., temminckii, badius, rufomitratus, and kirkii. The sections pertaining to reproduction deal with more than behaviour. They present information and conclusions regarding a wide range of subjects related to reproduction, such as the timing of births, interbirth intervals (IBIs), reproductive success and its relation to dominance status, age of sexual maturity, sexual swellings, twinning, etc.Less

Much current research in social psychology has demonstrated unconscious impulses or guides to situationally appropriate behavior. These come from immediate and automatic evaluative, motivational, and perceptual mental processes. These in turn come from evolution, from culture, and from imitative and vicarious early learning; in children as well as adults they provide behavioral suggestions or impulses that we commonly act on though we do not intend or are aware of those influences. It is concluded from this research that we do not need the philosophical concept of free will to explain the origin of our own action, and to insert the concept of free agency is contrary to a natural science understanding of human action.Less

This chapter provides an overview of the role of two mammalian neuropeptide hormones, oxytocin (OT) and arginine vasopressin (AVP), in the development and expression of social behaviors, including selective behaviors that are indicative of social bonds. It begins by giving a general background on social behavior in monogamous species, as well as the previously studied physiological and behavioral effects of OT and vasopressin. This is followed by a description of animal studies describing the role of OT and AVP during development. It then discusses current knowledge of possible developmental actions of OT and AVP, especially as these may be related to psychopathologies in later life.Less

More
This chapter examines how the logic of inclusive fitness theory can be mathematically formalized using the Price equation, and how that formalization can be used to derive Hamilton's rule in its simplest form, as applied to unconditional behaviors having additive effects on fitness. Various biological phenomena, such as sex allocation and working policing within eusocial insect colonies, have been analyzed by considering what strategies maximize individuals' inclusive fitness, and how observed social behaviors should correlate with quantities such as relatedness. The chapter derives Hamilton's rule by introducing some notation for the effects of behaviors on fitnesses of individuals that interact socially, to make explicit precisely how genes (and later phenotypes) affect fitness, and to give a general form of Hamilton's rule that will apply to any (unconditional, additive) behavior regardless of its details. It shows that inclusive fitness is a genuinely novel extension of the classical fitness studied by Charles Darwin, R. A. Fisher, and others.Less

This book has examined the genesis, the logic, and the generality of social evolution theory. In particular, it has presented evolutionary explanations of the many social behaviors we observe in the natural world by showing that William D. Hamilton's inclusive fitness theory provides the necessary generalization of classical Darwin–Wallace–Fisher fitness. This concluding chapter discusses the limitations of the analyses presented in this book and assesses the empirical support for inclusive fitness theory, focusing on microbial altruism, help in cooperative breeders, reproductive restraint in eusocial species, and the evolution of eusociality and cooperative breeding. It also considers more advanced topics in social evolution theory, including sex allocation, genetic kin recognition, spite, and the evolution of organismality.

In particular, it has presented evolutionary explanations of the many social behaviors we observe in the natural world by showing that William D. Hamilton's inclusive fitness theory provides the necessary generalization of classical Darwin–Wallace–Fisher fitness. This concluding chapter discusses the limitations of the analyses presented in this book and assesses the empirical support for inclusive fitness theory, focusing on microbial altruism, help in cooperative breeders, reproductive restraint in eusocial species, and the evolution of eusociality and cooperative breeding. It also considers more advanced topics in social evolution theory, including sex allocation, genetic kin recognition, spite, and the evolution of organismality. Finally, it reviews theoretical approaches to studying social evolution other than replicator dynamics and the Price equation, such as population genetics, class-structured populations, and maximization approaches.

This book is the result of a collaborative effort by eleven anthropologists and six economists, and questions the motives that underlie the ways that humans interact socially, and whether these are the same for all societies, and are part of our nature, or are influenced by our environments. Over the past decade, research in experimental economics has emphatically falsified the textbook representation of Homo economicus, with hundreds of experiments that have suggested that people care not only about their own material payoffs but also about such things as fairness, equity, and reciprocity. However, this research has left fundamental questions unanswered: are such social preferences stable components of human nature; or, are they modulated by economic, social, and cultural environments? Until now, experimental research could not address this question because virtually all subjects had been university students, and while there are cultural differences among student populations throughout the world, these differences are small compared with the full range of human social and cultural environments. A vast amount of ethnographic and historical research suggests that people's motives are influenced by economic, social, and cultural environments, yet such methods can only yield circumstantial evidence about human motives. In combining ethnographic and experimental approaches to fill this gap, this book breaks new ground in reporting the results of a large cross‐cultural study aimed at determining the sources of social (non‐selfish) preferences that underlie the diversity of human sociality. The same experiments that provided evidence for social preferences among university students were performed in fifteen small‐scale societies exhibiting a wide variety of social, economic, and cultural conditions by experienced field researchers who had also done long‐term ethnographic field work in these societies. The results, which are given in chs. 4 to 14, demonstrated no society in which experimental behaviour is consistent with the canonical model of self‐interest, and showed that variation in behaviour is far greater than previously thought, and that the differences between societies in market integration and the importance of cooperation explain a substantial portion of the variation found (which individual‐level economic and demographic variables could not). The results also trace the extent to which experimental play mirrors the patterns of interaction found in everyday life. The book has three introductory chapters that include a succinct but substantive introduction to the use of game theory as an analytical tool, and to its use in the social sciences for the rigorous testing of hypotheses about fundamental aspects of social behaviour outside artificially constructed laboratories, and an overview and summary of the results of the fifteen case studies.Less

This chapter presents an alternative view to the notion that complex social behaviors in primates require complex brain processes. It argues that social behavior in primates may be mediated by relatively simple rules that use the structure of the social environment as a scaffold. This is in opposition to the notion that social knowledge must be explicitly represented by specialized neural circuits. The complexity of the social environment is, in essence, an emergent property of these simple rules of social engagement.Less

Social behavior has long puzzled evolutionary biologists, since the classical theory of natural selection maintains that individuals should not sacrifice their own fitness to affect that of others. This book argues that a theory first presented in 1963 by William D. Hamilton—inclusive fitness theory—provides the most fundamental and general explanation for the evolution and maintenance of social behaviors in the natural world. The book guides readers through the vast and confusing literature on the evolution of social behavior, introducing and explaining the competing theories that claim to provide answers to questions such as why animals evolve to behave altruistically. Using simple statistical language and techniques that practicing biologists will be familiar with, the book provides a comprehensive yet easily understandable treatment of key concepts and their repeated misinterpretations. Particular attention is paid to how more realistic features of behavior, such as nonadditivity and conditionality, can complicate analysis. The book highlights the general problem of identifying the underlying causes of evolutionary change, and proposes fruitful approaches to doing so in the study of social evolution. It describes how inclusive fitness theory addresses both simple and complex social scenarios, the controversies surrounding the theory, and how experimental work supports the theory as the most powerful explanation for social behavior and its evolution.Less

This book demonstrates the generality of inclusive fitness theory, with particular emphasis on its fundamental evolutionary logic. It presents the basic mathematical theory of natural selection and shows how inclusive fitness theory deals with more complicated social scenarios. Topics include the Price equation, Hamilton's rule, nonadditive interactions, conditional behaviors, heritability, and maximization of inclusive fitness. This chapter provides a brief historical introduction to the problem of apparent design in biology, evolutionary explanations of this, and in particular, evolutionary explanations of individual behaviors that appear designed to benefit not the individual themselves, but other members of their species. It examines how social behaviors can be shaped by natural selection and discusses the problem of providing an evolutionary explanation of self-sacrifice by individuals, altruism in group selection, and multilevel selection theory.Less

This book presents a theory of the recent emergence of a right to security and of its protection by the criminal law in the UK. It states that the protection of such a right makes sense of the liabilities found in much of the expansive criminal legislation enacted under that government. This book identifies the normative source of the right to security in the idea of vulnerable autonomy. It demonstrates that this idea is axiomatic to political theories that have enjoyed a preponderant influence across the political mainstream, well beyond the ranks of the Labour government. It considers the continuing influence of these normative commitments on the Coalition government's policy. The book explores how the contemporary criminal law's institutionalization of a right to security differs from the law's earlier protection of security interests. It exposes the paradox presented by laws that declare their own lack of authority by threatening punishments that are justified on the assumption that the normal condition of the representative subject of law is one of feeling vulnerable to criminal victimization. The book presents unorthodox criminal law theory in two respects. First, it offers an explanatory political sociology of a contemporary trend in the criminal law's ‘special part’ rather than a philosophical treatment of the law's general principles. Second, rather than applying a pre-existing sociological or philosophical theory to the law, it develops its theoretical explanation from a detailed legal analysis and reconstruction of New Labour's flagship criminal justice policy, the Anti-Social Behaviour Order.Less
