BBC Walking with Monsters - Life Before Dinosaurs 1
Episode 1: Water dwellers
This episode covers the Cambrian period up through the Silurian period and the Devonian period. The majority of animal life during this age was restricted to the ocean. As the first creatures evolve in the seas, the never ending fight between the hunter and the hunted begins, although there were a few species that began moving onto land for food and into freshwater sources within the continents for a safe haven from predators. Follow the evolution of life from its small beginning to the first animals to conquer dry land.
