A multitude of academic disciplines explore the complex networks of relationships between humans and other beings. Through the lens of the Native American Graves Protection and Repatriation Act (NAGPRA), I describe human/non-human relationships as they are represented in museums and other repositories. I introduce museum “collections” and “objects,” including animals, instead as beings which may have roles, responsibilities, and agency in their relationships with living humans. Participants are invited to consider the changing relationships between human and non-human beings through time, and to reflect on how we identify non-human “beings” and our responsibilities to them in our work and lives.
