Pearson, H.C. 2011. Sociability of female bottlenose dolphins (Tursiops 
spp.) and chimpanzees (Pan troglodytes): understanding evolutionary 
pathways toward social convergence. Evolutionary Anthropology 20: 85-95 

On the northern tip of New Zealand’s South Island, bottlenose dolphins (
Tursiops truncatus) occasionally pass through Admiralty Bay in large, 
fast-traveling groups of 100 or so individuals. Watching such a group race 
and splash through the water is reminiscent of a stampeding herd of 
ungulates, cetaceans’ closest terrestrial ancestors. At other times, 
smaller social groups of bottlenose dolphins appear in the bay and provide 
a glimpse of the behavioral complexity that dolphins share with their 
distant relatives, the primates. Despite being evolutionarily separated 
for 95 million years and evolving in vastly different environments, 
cetaceans and primates share striking similarities in behavior, 
socioecological problem-solving, life-history patterns, and cognitive 
capacity. By comparing attributes shared by primates and cetaceans, 
distraction from phylogenetic ‘‘noise’’ is minimized and our understanding 
of evolutionary pathways is enhanced. In particular, cetaceans provide a 
powerful outgroup for studying the evolution of primate social 
organization.
