I stumbled upon this audio book by sheer accident during my recent visit to a public library. The book’s title and synopsis piqued my interest, and I plunged into it eagerly. Written in a lighthearted, humorous style, in a language that is easily understood by a non-scientist, the book tells a fascinating story of evolutionary forces shaping life on our planet, of interconnectedness of all living organisms and their constant interaction among themselves and their environment. The book provides a fresh perspective on disease and explains how some hereditary conditions helped our ancestors fulfill the ultimate objective programmed into every living cell: survive and reproduce. If you have a natural curiosity and an appetite for science, this book is a must read.
