Starting with the basic questions, "What does it mean to be human?" and "What does it mean to be me ?" Who Am I? by Richard Walker is an exciting, unusual, and thought-provoking exploration of what human identity is at the most fundamental level. Sweeping through biology, biotechnology, psychology, and a range of social themes—with room for the astonishing, surprising, and the bizarre—this is a book that delves deep into our notions of who we are, and what an amazing species we have become. From how we learn language, to what light DNA studies can shed on ancient history, to why so much money is spent on fighting the aging process, and how emotions help us interpret our world, this book enlightens on a whole range of physical and metaphysical questions. Fresh, engaging design and a compelling question-and-answer text make this a book that will intrigue, inspire, and inform readers of all ages.
