In 1999 the Australian Museum in Sydney began a project to clone a thylacine from genetic material preserved since the early 20th century, but after some success the museum realized in February 2005 that the DNA had been tainted by the ethanol preservative. Fascinated with the study of species that are extinct or near extinct and the conundrum that it is impossible to prove that the thylacine does not exist, Rachel Berwick became intrigued by the initial cloning reports and focused her attention on the thylacine. Its disappearance, the rich mythology surrounding it, and the attempt to recover it inspired her Hovering Close to Zero (2000). Working from the remaining photographs of a live Tasmanian tiger and about 60 seconds of film from the 1920s, the artist produced a piece that laments loss and explores notions of recovery.
