What is a human? Every person would like to know what or who he or she is. In her fascinating search for the molecule of life the biochemist Renée Schroeder has made groundbreaking discoveries. In her search for answers she does not hesitate to question the possibilities of genetics and in the dispute between belief and science clearly positions herself in favor of a society based on knowledge. In all this, she is never afraid addressing on taboos. The question of the origin of life leads Schroeder far beyond the boundaries of her own scientific field and towards fundamental issues of being. Where do we come from, where are we going? How does evolution work and what role does chance play? Renée Schroeder’s undogmatic approach to the boundaries of our perception opens the door to a new way of thinking and new perspectives. In this book the passionate scientist explains what applied bioethics is and what the hen-egg question means for our future, all while guiding us through the wonderful world of molecules.

70, 000 years ago, humans were first able to form a thought about something that didn't exist. What sounds simple actually marks the birth of human culture and poses the outset for a range of inventions that have formed human nature and haven't necessarily changed us for the better. We thought up myths and religions and invented languages, money and racism. Now humankind is about to complete its greatest invention: itself. Science allows us to continue our own evolution. Renée Schroeder looks back at the short period of humankind's existence, takes a detour into genetics and proclaims a new age of enlightenment.
