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
