Prey must constantly avoid predators, and any defensive adaptation boosts survival. Speed is a key defense-antelope are built to run, chased by sprinters like cheetahs. Over time, predators evolved to be fast, and prey evolved to be faster. Antelope also travel long distances for food. Ostriches, though flightless, are the fastest-running birds. The Golden Wheel spider escapes danger by turning into a rolling wheel. In the Race of Life, survival depends on clever, sometimes surprising adaptations. Režie: Max Serio, Bettina Dalton Rok: 2015
