“Replaying Life’s Tape” doesn’t refer to sentimental moments or monologues seeking closure. Mariana Castillo Deball’s first Australian exhibition instead contemplates evolutionary history. The artist conceived her approach when she visited South Australia’s Ediacara Hills, where fossils of a new archaeological age were discovered in 1946. Traversing the rocky terrain, Castillo Deball envisioned creatures 600 million years old—the multicellular organisms that inhabited murky seafloors. What did they look like? In sculptures, installations, drawings, and prints, Castillo Deball imagines a world before the coming of complex forms of life. —E.C.
