No, your eyes are not deceiving you: there really is a giant chimpanzee currently sitting on Arts Centre Melbourne. The scuplture is of David Greybeard, the chimp that helped enable the research of Dr Jane Goodall
'David Greybeard' is a new, temporary sculpture was created by Lisa Roet to inspire thought on humanity's relationship with nature and to mark the 60th anniversary into Dr Jane Goodall's pioneering research into chimpanzees.
For those unfamiliar with Dr Goodall's work, she redefined how science perceived chimpanzees (and to a greater extent, all animals) starting with her observations on chimp behaviour. Prior to her research, it was thought that only humans were smart enough to use tools. Goodall, however, proved that chimps also used tools – a breakthrough made possible when a wild chimpanzee (which Goodall nicknamed David Greybeard) allowed her to observe his community.
