evolution in toothed whales.  Trends in Ecology and Evolution 13:


 Two contrasting results emerge from comparisons of the social systems
 of several odontocetes with terrestrial mammals.  Researchers have
 identified remarkable convergence in prominent features of the social
 systems of odontocetes such as the sperm whale and bottlenose dolphin
 with a few well-known terrestrial mammals such as the elephant and
 chimpanzee.   In contrast, studies on killer whales and Baird's
 beaked whale reveal novel social solutions to aquatic living.  The
 combination of convergent and novel features in odontocete social
 systems promise a more general understanding of the ecological
 determinants of social systems in both terrestrial and aquatic
 habitats, as well as the relationship between relative brain size and
 social evolution.
