Originally published in 2005, this book is now republished in the Oxford Landmark Science series. Includes a new preface from the author, reflecting on recent developments and breakthroughs in the world of mitochondrial research.
Mitochondria are tiny structures located inside our cells that carry out the essential task of producing energy for the cell. They are found in all complex living things, and in that sense, they are fundamental for driving complex life on the planet. But there is much more to them than that.
Mitochondria have their own DNA, with their own small collection of genes, separate from those in the cell nucleus. It is thought that they were once bacteria living independent lives. Their enslavement within the larger cell was a turning point in the evolution of life, enabling the development of complex organisms and, closely related, the origin of two sexes. Unlike the DNA in the nucleus, mitochondrial DNA is passed down exclusively (or almost exclusively) via the female line. That's why it has been used by some researchers to trace human ancestry daughter-to-mother, to 'Mitochondrial Eve'. Mitochondria give us important information about our evolutionary history. And that's not all. Mitochondrial genes mutate much faster than those in the nucleus because of the free radicals produced in their energy-generating role. This high mutation rate lies behind our ageing and certain congenital diseases. The latest research suggests that mitochondria play a key role in degenerative diseases such as cancer, through their involvement in precipitating cell suicide.
Mitochondria, then, are pivotal in power, sex, and suicide. In this fascinating and thought-provoking book, Nick Lane brings together the latest research findings in this exciting field to show how our growing understanding of mitochondria is shedding light on how complex life evolved, why sex arose (why don't we just bud?), and why we age and die. This understanding is of fundamental importance, both in understanding how we and all other complex life came to be, but also in order to be able to control our own illnesses, and delay our degeneration and death.
"Challenging, but rewarding."
– Vanessa Thorpe, Observer
"Its the most interesting and significant addendum to Darwin's theory I think I've come across since Richard Dawkins explained how genes are the mechanism for evolution."
– Independent on Sunday
"An enthralling account [...] The author has accomplished something quite breathtaking [...] Moreover, he brings the science alive [...] he is always accessible lively , thought provoking and informative. Every Biologist should read this book."
– Biologist Philip John
" [...] for anyone interested in some of the most profound questions of 21st century science. the central proposals of Power, Sex, Suicide are clearly and forcefully propounded [...] This is a new take on why we are here. Do, please, read this book."
– John F. Allen, Nature
"Full of startling insights into the nature and evolution of life as we know it."
– The Economist
"Impressive [...] readable, provocative, and often persuasive [...] undoubtably important. This is an exciting and unusual book."
– Jonathan Hodgkin, Times Literary Supplement
"Magnificent [...] explains life's workings, fabric, and inner logic with a previously unapproachable coherence."
– Oliver Morton, Prospect Magazine
"One of the most interesting stories modern biology has to tell."
– Steven Rose, The Guardian
"An enjoyable and readable book. Nick Lane has achieved the difficult goal of taking selected aspects of a complex field and making them intelligible [...] fascinating."
– David G. Nicholls, Science
"I defy anyone to read this book and not come out amazed by the incredible subtlety, complexity, and downright unlikeliness of the mechanisms of biological construction. This book opens up the secrets with an obvious delight from Lane that the readers are likely to share."

Nick Lane is a British biochemist and writer. He was awarded the first Provost's Venture Research Prize in the Department of Genetics, Evolution, and Environment at University College London, where he is now Professor of Evolutionary Biochemistry. Professor Lane's research deals with evolutionary biochemistry and bioenergetics, focusing on the origin of life and the evolution of complex cells. He was a founding member of the UCL Consortium for Mitochondrial Research, and is leading the UCL Research Frontiers Origins of Life programme. He was awarded the 2011 BMC Research Award for Genetics, Genomics, Bioinformatics and Evolution, and the 2015 Biochemical Society Award for his sustained and diverse contribution to the molecular life sciences and the public understanding of science. His books include Oxygen: The Molecule that Made the World (OUP, 2002; 2016).
