This third installment of the Triumph of Life series investigates nature's "arms race" -- evolution and the survival of the fittest. The program takes an in-depth look at how creatures adapt to environmental threats to their physical safety, emphasizing how animals behave in order to protect themselves or to find food. Experts discuss how some animals have evolved to the point that their bodies provide them with the coloring they need for camouflage, while others like cheetahs have developed an extremely fast running ability. Sharper teeth, tougher body armor, and other physical traits are critical to the featured species as they try to survive their own form of an "arms race."
