Details. Condition: BRAND NEW. Format: Paperback. ISBN: 9781780220901. Publisher: W&N (Weidenfeld & Nicolson). Age Range: Adult. Overview. Professor Tim Spector's "Identically Different: Why You Can Change Your Genes" is a groundbreaking work of popular science that challenges what readers thought they knew about heredity. Drawing on decades of research into twins, epigenetics and the microbiome, Spector reveals that our genes are far less fixed than once believed. This paperback is ideal for science-curious adults, students of biology and medicine, and anyone wanting to understand how lifestyle and environment can reshape who we become, physically and behaviourally, across a lifetime.. About the Book. As one of the world's leading experts on twin studies, Tim Spector spent years comparing identical twins who share exactly the same DNA yet often lead startlingly different lives, developing different diseases, personalities and even political views. In "Identically Different", he uses this research as a launchpad into the fast-moving science of epigenetics: the study of how genes are switched on and off by diet, stress, chemicals and early life experience. Rather than treating the genome as a fixed blueprint, Spector shows it behaves like a dynamic, responsive code capable of adapting to its surroundings and, in some cases, passing changes on to future generations.. The book ranges across cancer risk, autism, sexuality, obesity, addiction and ageing, grounding complex genetic science in relatable human stories. Spector explains how gut bacteria, nutrition and environment interact with our DNA in ways unimaginable a generation ago, questioning long-held assumptions about nature versus nurture. Written in clear, witty and accessible prose, "Identically Different" turns cutting-edge epidemiology into a compelling read for anyone curious about human identity and how our choices shape our biology.. Key Benefits. Explains epigenetics in plain English — how genes switch on and off with diet, stress and environment.. Draws on world-leading twin studies to show why identical DNA can produce very different people.. Explores real-world implications for cancer, autism, obesity, sexuality and ageing.. Written by a globally respected epidemiologist — authoritative yet highly readable.. Ideal for science students, healthcare professionals and general readers alike.. A thought-provoking gift for anyone curious about genetics, health or identity.. About the Author. Professor Tim Spector is a British epidemiologist, medical doctor and one of the world's most cited researchers in genetics and the microbiome. He leads the Department of Twin Research at King's College London and founded the TwinsUK registry, one of the largest twin studies in the world. His pioneering work on epigenetics and gut bacteria has reshaped public understanding of health and disease. Spector is also the bestselling author of "The Diet Myth" and "Spoon-Fed", making him one of the UK's most trusted voices in popular science.. Why You'll Love This Book. You'll love this book for the way it turns dense genetic science into a gripping, human story. Spector's twin studies and epigenetics research make for genuinely surprising reading, perfect for curious minds who want clear, evidence-based insight into health, identity and family history without wading through a dry, jargon-heavy textbook..
