The recent fatal attack of a SeaWorld trainer by the orca Tilikum has led to renewed questions about how humans should deal with potentially intelligent animals. Was Tilikum’s action premeditated, and how should that possibility influence decisions on the animal’s future treatment? Orcas, like their close relatives, dolphins, certainly seem smart, though researchers debate just how intelligent these cetaceans are and how similar their cognition is to humans. Should we ever treat such creatures like people? For centuries it seemed obvious to most people what separated them from other animals: Humans have language, they use tools, they plan for the future, and do any number of things that other animals don’t seem to do. But gradually the line between “animal” and “human” has blurred. Some animals do use tools; others solve complicated problems. Some can even be taught to communicate using sign language or other systems. Could it be that there isn’t a clear difference separating humans from other life forms?
