Abstract:
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.
