How evolution shapes our lives: essays on biology and society. Sometimes we think that evolution is something that happened in the distant past, or that it's such a slow process its impact is almost invisible. But this book shows how evolution can actually be very rapid, and it explores the implications for evolution in our lives and society. This book contains twenty-three essays that explore why understanding evolution is crucial in our lives, in everything from understanding climate change and food supply to what it means to be human itself.
