6. Invasion of the Land
Some 350 million years ago, evolution reached one of its most crucial stages when fish crawled from the water onto the land and became amphibians. Today, newts, salamanders, toads and frogs still survive in great quantities, and there is even one species of frog where the male gives birth from its mouth! Presented by David Attenborough.
