Dolphin Play: Evidence for Cooperation and Culture?
We agree that human culture is unique. However, we also believe that an understanding of the evolution of culture requires a comparative approach. We offer examples of collaborative behaviors from dolphin play, and argue that consideration should be given to whether various forms of culture are best viewed as falling along a continuum or as discrete categories.
