As the only living beings, we humans have succeeded in colonising the entire earth, developing language and writing and networking ourselves worldwide. What are our evolutionary roots and how do they still determine our behaviour today? For the first time, a TV team accompanies the award-winning photographer Jimmy Nelson on his adventurous expeditions to the last original tribes on earth. With play scenes, the films delve into the history of the evolutionary biologist Charles Darwin. He realised that apes and humans have a common ancestor. What connects us with our closest relatives and what distinguishes us from them is explored by Leipzig developmental psychologists. They compare the behaviour of chimpanzees and children and discover the nature of humans in their capacity for empathy and cooperation. With fascinating experiments, psychologists reveal the mechanisms of mate choice and how love came into the world. Body language expert and “mind reader” Thorsten Havener unlocks the secrets of non-verbal communication.
