A grizzly bear, left, and a sculpture of a Steller's sea cow, upper right, are displayed as guest curator J.B. MacKinnon, centre, speaks during a media preview of the "Rewilding" exhibition at the Museum of Vancouver in Vancouver, B.C., on Tuesday February 25, 2014. The exhibition aims to challenge the perception of what is natural to Vancouver through taxidermy specimens, 3D models and media that explore the city's nature as it once was, is currently and how it could be in the future. It opens to the public Thursday and continues until September 1.DARRYL DYCK/The Canadian Press
