Dogs are more skillful than great apes at a number of
tasks in which they must read human communicative signals indicatingthe location of hidden food. In this study, we found that wolveswho
were raised by humans do not show these same skills, whereasdomestic
dog puppies only a few weeks old, even those that havehad little human
contact, do show these skills. These findingssuggest that during the
process of domestication, dogs have beenselected for a set of
social-cognitive abilities that enable themto communicate with humans
in unique ways.
