This chapter describes repertoire-based methods for detecting and quantifying the social transmission of behavior based on a “snapshot” of the behavioral repertoires of individuals or groups. Repertoire-based methods often take the form of a group contrast approach, where the researcher attempts to ascertain whether different groups have different behavioral repertoires, which might be caused by a higher rate of social transmission within groups than between them. The chapter first considers approaches that can be applied to determine whether group differences in behavior exist, including the group contrasts approach and the method of exclusion. In particular, it discusses methods for assessing the genetic hypothesis and the ecological hypothesis. It also presents a model-fitting approach and a causal modeling framework. Finally, it highlights the limitations of studying social learning based solely on differences in repertoires.Less

This chapter is concerned with the Cambrian explosion. It considers only one particular kind of explanation for the Cambrian radiation: that major innovations in animal body plan were produced from relatively few genetic changes of large phenotypic effect. It investigates the developmental genetic hypothesis of the origin and maintenance of body plans. This chapter suggests that the genetic architecture underlying body plans was not set during the Cambrian and has been immutable since. It shows that the link between body plan and phylum can become blurry when the minor phyla are considered.Less
