Part 1: Origins: Search for and discover the origin of today's animal life. Part 2: Life On the Move: When we think of animals, we think of movement. Surprisingly, the diverse and graceful ballet of movement may have started with a single group of creatures whose descendents were the first to harness the power of muscles and nerves.

Part 1: The First Hunter - The first animal to develop a head, eyes and a brain also pioneered a new way to survive: it would become Earth's first hunter. Dramatic new evidence points to an unlikely and oddly charismatic subject...the flatworm.

Part 1: The Conquerors: For hundreds of millions of years, animal life resided only in the oceans. And then, in one extraordinary event, something happened that enabled one group of animals to emerge from the sea. Follow scientists as they track how the shape of life transformed to create the animals that led the first successful land invasion and were the first to pioneer flight.

The Shape of Life tells the gripping and magnificent tale of the beginnings of all animal life.
