The final episode deals with the evolution of the most widespread and dominant species on Earth: humans. The story begins in Africa, where, some 10 million years ago, apes descended from the trees and ventured out into the open grasslands in search of food. They slowly adapted to the habitat and grew in size. Their acute sense of vision led to them standing erect to spot predators, leaving their hands free to bear weapons. In addition, the primitive apemen also had stones that were chipped into cutting tools. Slowly, they grew taller and more upright, and their stone implements became ever more elaborate.
Groundbreaking documentary which follows a Japanese-led team of scientists as they attempt to shed light on the mysterious world of deep sea sharks. Only 50 specimens of the newly discovered 'megamouth' have ever been sighted. Over four years, scientists and film crews voyaged in midget submarines into the depths of Suruga Bay and Sagami Bay to film them. Prehistoric 'living fossil' sharks such as bluntnose sixgill sharks, goblin sharks and frilled sharks also lurk in the bay. As part of the investigation, a sperm whale carcass was placed at the bottom of the bay to attract these sharks, which were then studied and observed from the submersible vessels. Revealing in detail the previously unknown behaviour of deep sea sharks, the film unravels another of the intriguing mysteries of our planet's biodiversity. Narrated by David Attenborough.

In the second episode; India is a subcontinent surrounded by mountains. We explore the little-known Western Ghats at the edge India's south. Here are Monsoon hills covered in lush forests and tea gardens which shelter some of the greatest biodiversity in the world. But far to the north lies the mighty Himalayas - so vast they drive the climate by capturing the monsoon winds and protect India from the northern chill. It's a unique world full of life.
