The Cambrian explosion was one of the most spectacular events in the history of life. On a short window of geological time and abundance of new animals and new body designs arose without evidence of evolutionary ancestors. Charles Darwin viewed this time as an inexplicable mystery - he had envisioned the evolution of life through a multitude of small, undirected steps, yet the fossil record revealed no such pattern of gradual development. Filmed on four continents, this documentary examines the Cambrian fossils, the explosion of life that was actually an explosion of biological information. From the assembly instructions in DNA to the embryonic blueprints that directed the first complex animals, this information points not to undirected evolution but to foresight, purpose, and Intelligent Design.
