"Life on the Move" (Part 2) explores how animal movement ("life's glorious dance," narrator Peter Coyote calls it) began. The world's first movers: ancient sea anemones, which developed "sensory tentacles that could reach out and touch the world" some 500-million years ago. Their primary contribution: nerve and muscle tissues. "They invented wiring," biologist Ian Lawn says. "This was an amazing leap for the animal world." And one anemone evolved into jellyfish, the world's first swimmers.
