Biologists teach that all living things on Earth are related. Is there any solid evidence to back this claim? Join us as we explore the facts! We start with a close look at the origin of whales from land mammals, and then touch on the origins of several other critters, including our own species.
Indonesia's marine rainforests are under threat, and rising sea temperatures and destructive fishing practices have taken a toll. However, conservation initiatives in hundreds of protected marine zones have given hope to the giant manta rays, 300 species of coral, and six of the world's seven sea turtle species that call this ecosystem home.
David Attenborough narrates a documentary looking at the wildlife of the most stunning mountain range in the world, home to snow leopards, Himalayan wolves and Tibetan bears. Snow leopards stalk their prey among the highest peaks. Concealed by snowfall, the chase is watched by golden eagles circling above. On the harsh plains of the Tibetan plateau live extraordinary bears and square-faced foxes hunting small rodents to survive. In the alpine forests, dancing pheasants have even influenced rival border guards in their ritualistic displays. Valleys carved by glacial waters lead to hillsides covered by paddy fields containing the lifeline to the East, rice. In this world of extremes, the Himalayas reveal not only snow-capped mountains and fascinating animals but also a vital lifeline for humanity.

Sophie explores the world of silent communication in the animal kingdom and the human world - showing how much we can actually say without ever opening our mouths or making a noise. She reveals how some species have harnessed bacteria to generate light and how light messages are used by insects and deep-sea fish for a range of reasons, including attracting prey. Exploring how body language communicates huge amounts about us and other species, Professor Scott shows why a dog's wagging tail does not always mean it is happy and how humans can tell a lot about someone's state of mind from their posture alone. She reveals why yawns and smiles are contagious and how this can play a key role in social bonding and cohesion.
