Research on the evolution of social behaviour has been dominated by genetic relatedness for a long time; however, both recent empirical studies and theoretical concepts give growing evidence for ecological factors acting as very prominent additional or alternative driving forces in social evolution. Now the time is ripe to investigate similarities and differences in the course of social evolution in different animals. This book brings together renowned researchers working on sociality in different animals. For the first time, they compile the evidence for the importance of ecological factors in the evolution of social life, ranging from invertebrate to vertebrate social systems, and evaluate its importance versus that of relatedness.

The study of animal behaviour has become one of the fastest growing b- logical disciplines in recent decades. This development can be easily - ferred, for example, from the steady increase in the total number of pub- cations on any aspect of animal behaviour, in particular also in journals with a more general readership (e. g. Nature, Proceedings of the Royal - ciety or Current Biology), the ever-increasing number of participants at - ternational conferences (e. g. IEC or ISBE), and from the growing numbers of students choosing courses in this field. This development has several causes, of which I find three particularly compelling. First, it is incre- ingly being appreciated that behaviour is the crucial level at which an in- vidual's genotype and phenotype interface with the environment. Rec- nising behaviour as the main mechanism animals employ to ascertain their homeostasis, growth, survival and reproduction therefore provides a deep understanding of organismal integration and adaptation.Second, the ast- ishing success of the study of animal behaviour also has importantly to do with the intellectual flexibility and methodological inter-disciplinarity - quired for comprehensive analyses of behaviour. Today, students of beh- iour are jacks-of-all-trades; importing, applying and improving methods from many neighbouring disciplines, such as molecular genetics, physi- ogy or micro-electronics, as well as concepts and theories from less ob- ous sources, such as economics or sociology, for example.
