Preface
The papers in this volume were originally presented at a conference held at King's College, Cambridge on 4-6 July 1980, to mark the culmination of the King's College Sociobiology project. For this conference, all those who had been closely involved with the project were invited to submit papers concerned with unsolved problems in sociobiology.
In order to understand how the King's Sociobiology group came to be formed it is necessary to understand that Cambridge Colleges are relatively independent of the University and some have great wealth of their own. Every so often a college that is rich enough can behave like a Renaissance patron and do something that a British university, largely dependent on State support, could rarely do. My own College, King's, decided in the midsixties to use some of its considerable resources to help subjects that looked exciting but did not have an adequate toehold within the University. It established a Research Centre in which a group of people within the same subject could hold Fellowships. Each programme was to last up to five years and, in addition to themselves, members could draw in short-term visitors, research assistants and graduate students. The idea was that a lively group would give sufficient impetus to their subject to keep it going in Cambridge after the project had ended in the Research Centre.
Early in 1975 Nick Humphrey and I, as Fellows of King's, suggested to the College that the Research Centre should establish a project in behavioural ecology. During the sixties and early seventies the fruits of numerous field studies of animals were starting to suggest coherent explanations for the ways in which social behaviour might be related to ecological conditions. The ideas were brought together by the increasingly powerful use of evolutionary theory. A mass of seemingly unrelated evidence started to make sense and the subject looked exceptionally promis-

ing. King's decided to support behavioural ecology and, once it had done so, the Convenor of the Research Centre, Donald Parry, took over the job of organising the project. Along with running a busy University Department of his own, he handled with consummate efficiency every stage from advertising the Fellowships to administering the most active phase of the programme. A lot of its subsequent success was due to his efforts.
After the project had been running for a year, its title was changed from Behavioural Ecology to Sociobiology since we wanted to include functional studies of social behaviour which were not necessarily ecological in character. The term 'Sociobiology' had been in use since the late 1940s; indeed, the present-day American Animal Behavior Society had grown out of a section of the Ecological Society of America and the American Society of Zoologists called 'Animal Behavior and Sociobiology'. However, we should, perhaps, have been quicker to realise how much opinion would be polarized by the recent attempts to inject a particular brand of biology into the social sciences. The lacerations resulting from the ensuing ideological conflict have not yet healed, and in many places 'Sociobiology' is either a battlecry or a term of abuse. Fortunately, the Research Centre project was unaffected, largely because the people who were appointed to the group were strongly committed to empirical research. Nobody who knew their work could accuse them of doing bad science. Furthermore, they would tolerate neither sloppy argument nor extravagant generalisations from studies of animals to humans.
After two years of recruiting the Sociobiology Group had four Fellows with longer-term appointments: Brian Bertram, Tim Clutton-Brock, Dan Rubenstein and Richard Wrangham. They were joined by Robin Dunbar who had been awarded one of the much prized Science Research Council Advanced Fellowships. During the course of the project Adam Lomnicki and Geoff Parker each came for one year while on sabbatical leave from their Universities. Peter Jarman, Nancy Knowlton and Napoleon Chagnon worked for shorter periods in the Research Centre and, while they did not hold Fellowships, played vigorous parts in its intellectual life. In addition, Elizabeth Thompson, who was already a Fellow of the College, brought much needed mathematical skills to bear on some of the problems that were being discussed, and Steve Albon collaborated throughout with Tim Clutton-Brock on their study of red deer. Of the numerous other people who, by their talks and discussions, contributed so much to making the years of the project exciting and enjoyable, Nick Davies, Richard Dawkins, Paul Harvey, John Maynard Smith and PeterO'Donald were especially influential.

One of the most important aspects of the Research Centre's work was the weekly seminar. The talks and the discussions they generated were excellent and, what proved crucial, attracted a regular audience from groups scattered throughout Cambridge and East Anglia. People from different Departments and research groups suddenly found that they had interesting things to say to each other. The Research Centre was operating exactly as it should do and providing a focus for discussion and an impetus for further research. After four productive years which culminated in the conference from which this book has been produced, the Sociobiology Group has now dispersed. What remains behind is a widespread enthusiasm for studies of the evolution of behaviour and behavioural ecology and, at the same time, cool sanity about the issues. That legacy, along with each member's personal contribution to research, is the lasting achievement of the King's Sociobiology Group.

Acknowledgments
It is a very real pleasure to thank the Provost and Fellows of King's College for their interest, help and support in the Sociobiology Project over the last five years. For all of us, our time in the Research Centre provided opportunities for research and collaboration which would have been unavailable elsewhere. We are particularly grateful to Pat Bateson and Nick Humphrey for instigating the project; to Donald Parry and Herbert Huppert who administered the Research Centre together with the board of managers, for their help, sympathy and toleration in dealing with our various needs; to Hazel Clarke, the Research Centre's administrative secretary, for secretarial help and unflagging good humour; and to the staff of King's College for their part in making King's a pleasant place to work. We are also grateful to the staff of the Department of Zoology, the Sub-department of Animal Behaviour, and the Computer Centre, all of which provided us with specialized facilities unavailable in the Research Centre. Finally, we should like to thank the large number of colleagues who participated in the Research Centre's activities and whose stimulating interest and encouragement were the spur for so many of our activities.
