In this first episode Iain journeys from the spectacular caves of Vietnam to the remote deserts of Africa. He sees how plants first harnessed light from the sun and created our life-giving atmosphere. He uncovers the epic battle between the dinosaurs and the tallest trees on the planet. And, using remarkable imagery, he shows plants breathing - and for the first time talking to each other.

Ideas about the soul and the afterlife, of sin and God's purpose have shaped human thinking for thousands of years. Religious rituals remain embedded in the major events of our lives. In this thought-provoking series, evolutionary biologist Richard Dawkins asks what happens if we leave religion behind. He explores what reason and science might offer to inspire and guide our lives in religion's place. Can science bring understanding in the face of death, help us tell right from wrong, or reveal the meaning of life?

Paleontologist Professor Richard Fortey embarks on a quest to discover the extraordinary lives of rock pool creatures. To help explore this unusual environment he is joined by some of the UK's leading marine biologists in a dedicated laboratory at the National Marine Aquarium in Plymouth. Here and on the beach in various locations around the UK, startling behaviour is revealed and new insights are given into how these animals cope with intertidal life. Many popular rock pool species have survived hundreds of millions of years of Earth's history, but humans may be their biggest challenge yet.

For years our place in the universe was the subject of theologians and philosophers, but in 1960 scientist Frank Drake changed all that by using a radio telescope to search for signs of extra-terrestrial intelligence. Although the project resulted in silence, it led to one of the most seminal equations in science - the Drake Equation - which examined seven key elements necessary for ET intelligence to exist. To find out about the equation's influence, Dallas Campbell meets the scientists who have dedicated their lives to focusing on its different aspects.
