Evolve is a 2008 documentary television series on History. The series premiere, "Eyes", was nominated for an Emmy for Outstanding Science, Technology and Nature Programming. Each episode attempts to explain the evolutionary origins of a particular trait of living creatures: for example, Tyrannosaurus Rex's 13-inch teeth, the gecko's "Velcro-like" toe pads, and the bald eagle's "telescopic" vision capable of spotting a hare a mile away.
The ability to react and move can often mean the difference between life and death in the animal kingdom. Some animals have evolved into championship fliers, swimmers, and runners. What are the forces that create this need for speed, and how do animal bodies adapt to go into overdrive? In this episode, find out about nature's ultimate engine, muscle, how it evolved and how it works. Meet some of the fastest species on earth.
