In November 2014 I worked with historical geographer, Elizabeth Hennessy, in conjunction with The Nelson Institute’s event The Anthropocene Slam: A Cabinet of Curiosities, to problematize a discussion about de-extinction. In a presentation that revolved around a cryogenic freezer deposit box, Hennessy raised questions about the promise of re-building extinct animals from frozen DNA; the physiological, technological and ethical problems that may arise. This instruction manual on how to re-build a passenger pigeon accompanies a vial of pigeon keratin DNA (the protein that builds feathers) inside the cryo box. The manual is empty; all we have is data. These objects, together with others, will be exhibited as part of the upcoming Anthropocene exhibit at the Deutsches Museum in Munich, December 2014 “ January 2016. This exhibition is a joint project between the Deutsches Museum and the Rachael Carson Center.
