It all started with the molecules. Somehow these small particles forever changed life on our planet. In a brand new BBC documentary film, thanks to recent advances in graphics technology and computer graphics, you'll see with our eyes over this process, step by step, passing through millions of years of Earth's history. From the beginning of the origin of life in the ocean and to the complex inter-species relationships. You will learn how, through evolution man became a man. Why does our body is designed specifically so, and in no way different. And that allowed people to get ahead so grandly in the development of their own immediate family — the great apes.
