Pat Goodman, an animal behaviorist at Wolf Park in Battle Ground, Ind., gives a meat treat to a captive-bred wolf as a reward for choosing the correct paint can in experiments coordinated by University of Florida scientists. The scientists found that, confronted with a person pointing at one of two paint cans, wolves were just as likely as dogs to approach or smell the correct can. The results call into question the common notion that dogs have evolved a special sensitivity to their human masters during 14,000 years of domestication.
