Enhanced with spellbinding music, Ocean Origins invites us on an extraordinary adventure - 4 billion years in the world's oceans. This documentary film seeks to examine the process of evolution by looking at the many creatures of the sea that illustrate the way multi-cellular life emerged over literally billions of years. With fascinating footage of creatures that are still alive today, Ocean Origins shows how life forms diversified after the first primitive bacteria appeared - from the beginning of life until that incredible moment when the first vertebrate emerged onto dry land and opened the path to the conquest of the continents.
