'Gets right to the heart of what makes us what we are.Read it!' Angela Saini, author of Inferior and Superior: The Return of Race ScienceThe popular science equivalent of Who Do You Think You Are?Popular science master Brian Clegg's new book is an entertaining tour through the science of what makes you you. From the atomic level, through life and energy to genetics and personality, it explores how the billions of particles which make up you - your DNA, your skin, your memories - have come to be. It starts with the present-day reader and follows a number of trails to discover their origins: how the atoms in your body were created and how they got to you in space and time, the sources of things you consume, how the living cells of your body developed, where your massive brain and consciousness originated, how human beings evolved and, ultimately, what your personal genetic history reveals.
