Is there much in life that is more intriguing than the process of formation of body and mind? The origin and development of new life is one of the greatest biological mysteries, although each of us is its embodiment. How does one fertilized egg manage to turn into trillions of cells that make up a person? This book is not just an answer to the most difficult question of science, but a fascinating, almost a fictional account that interweaves the fascinating biology of the twenty-first century with a personal journey through the world of cutting-edge scientific research. Describing her journey as a scientist, Magdalena Zernicka-Goetz guides the reader through the dance of life performed by the cells that create the human embryo.
