Pikaia!

Synopsis
Science animation produced by the creators of Ghost in the Shell and Pokémon!

Near-future researchers Vince and Hanna travel back in time to the oceans of the Cambrian period over 500 million years ago, in search of the "lost code," the key to reviving the dying Earth. Join them and Pikaia, the "tester" that helps them find the lost code, as they encounter weird and wonderful creatures from the past!
The program also features academic commentary by Professor Andrew Parker from the Natural History Museum, UK, an internationally acclaimed authority on biology. Educational as well as fun, Pikaia! introduces children everywhere to the amazing biodiversity of creatures and the amusing history of evolution.
