Identically Different

A brand new and updated edition for 2024, including the latest insights on diet and weight management drugs, gene editing, cancer testing, anti-ageing, ultra-processed foods and much more

Professor Tim Spector, number one bestselling author of SPOON FED and FOOD FOR LIFE, reveals the astonishing new science that is changing everything we thought we knew about genes and identity.

Since the discovery of DNA, scientists have believed that genes are fixed entities that cannot be changed by environment. Spector's pioneering epigenetics studies, and the latest genetic research, show that our genes are more like plastic, able to change shape and evolve, and these changes can be passed on to future generations.

This dazzling guide to the hidden world of our genes will make you rethink everything from sexuality to religion, cancer to autism, politics to pubic hair, clones to bacteria, and what it is that makes us all so unique and quintessentially human.

Tim Spector's book turns genetics on its head. Lucid, surprising and with a very human face. It brings epigenetics alive. It is a great read! Michael Mosley

This science book guides us, via artful storytelling and ground breaking research using identical twins, to reconsider the flexibility and power of our genes. -- Ijeoma Onweluzo THE LADY
It is provocative stuff, but all couched in the fresh and fast-paced style of popular science. GOOD BOOK GUIDE
Spector will get you through many dinner parties. But, much more importantly, he will show how a certain kind of scientific fundamentalism collapsed under the burden of its inability to explain the world as it is - complex, flowing, changing - rather than as they would like it to be - simple and clear. Read him. SUNDAY TIMES
A fascinating and provocative book...Spector is a talented story-teller, weaving real-life accounts of identical twins into each chapter...This is an informative and thought-provoking tour of some of the most exciting areas in biology right now. Spector concludes by inviting us to imagine a future in which we see our genes as malleable, rather than as masters of our biological destiny - just one part of the endlessly complex and fascinating story of what makes each of us unique.
