This chapter investigates the emergence of novel traits that distinguish dogs from their ancestors. It does so from a proximal perspective; that is, what kind of mechanisms are behind the phenotypic difference between wolf and dog. It discusses the evolutionary mechanisms causing phenotypic changes; and similarities and differences between wolves and dogs. It argues that the difference between dogs and wolves cannot be attributed to a single, specific genetic or developmental process. Dogs seem to be an example of mosaic evolution where various phenotypic traits have been dissociated and the changes have been controlled by a wide array of genetic and epigenetic mechanisms.

Keywords:   dog behaviour, wolves, novel traits, phenotypic differences
