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. Oxford Landmark Science books are 'must-read' classics of modern science writing which have crystallized big ideas, and shaped the way we think.

Mitochondria are tiny structures within all our cells, believed to have once evolved from bacteria living independent lives. Drawing on cutting edge research, this book explores the fundamental role they play in some of the biggest themes in biology: evolution, the origin of the sexes, in growth, ageing, disease, and in death. - ;Power, Sex, Suicide, Complexity, Individuality, Fertility, Prehistory, Ageing, Death. These universal themes are all linked by mitochondria - the tiny structures located inside our cells - miniature powerhouses that use oxygen to generate power. There are hundreds of them in each cell, some 10 million billion in a human being. Once considered menial slaves, mere workhorses for complex cells with nuclei, their significance is now undergoing a radical revision. Mitochondria are now seen as the key ingredient that made complex life possible at all. For two billion years, bacteria ruled the earth without ever generating true complexity - a stasis that may still grip life on other planets. Then the union of two bacterial cells led to an evolutionary big bang, from which algae, fungi, plants and animals emerged. For mitochondria were once free-living bacteria, and still retain unmistakable traits of their ancestry, including some of their original DNA. Ever since their fateful absorption, the tortuous and unpredictable relationship between the mitochondria and their host cells has forced one evolutionary innovation after another. Without mitochondria, nothing would exist of the world we know and love. Their story is the story of life itself. Today, mitochondria are central to research into human prehistory, genetic diseases, cell suicide, fertility, ageing, bioenergetics, sex and the eukaryotic cell. Piecing together puzzles from the forefront of research, this book paints a sweeping canvas that will thrill all who are interested in biology, while also contributing to evolutionary thinking and debate. This is a book full of startling insights into the nature and evolution of life, and should be read by anyone who wants to know why we're here. - ;Challenging, but rewarding. - Observer;Full of startling insights into the nature and evolution of life as we know it. - Economist Best Books of the Year, 2005;An enthralling account...The author has accomplished something quite breathtaking...moreover,he brings the science alive...he is always accessible, livley, thought-provoking, and informative.

What would biology look like if it took the problem of natural evil seriously? This book argues that biological descriptions of evolution are inherently moral, just as the biblical story of creation has biological implications. A complete account of evolution will therefore require theological input. The Dome of Eden does not try to harmonize evolution and creation. Harmonizers typically begin with Darwinism and then try to add just enough religion to make evolution more palatable, or they begin with Genesis and pry open the creation account just wide enough to let in a little bit of evolution. By contrast, Stephen Webb provides a theory of how evolution and theology fit together, and he argues that this kind of theory is required by the internal demands of both theology and biology. The Dome of Eden also develops a theological account of evolution that is distinct from the intelligent design movement. Webb shows how intelligent design properly discerns the inescapable dimension of purpose in nature but, like Darwinism itself, fails to make sense of the problem of natural evil. Finally, this book draws on the work of Karl Barth to advance a new reading of the Genesis narrative and the theology of Duns Scotus to provide the necessary metaphysical foundation for evolutionary thought.

Just as Dr Michael Mosley’s Fast Diet – the original 5:2 – alerted the world to a healthy new way to lose weight, Fast Exercise turns conventional wisdom on its head when it comes to the workout Can you really get the benefits of exercise in just a few minutes a day? Michael Mosley and Peta Bee investigate the science behind a radically different approach to exercise – one that is incredibly time efficient. Research has shown the extraordinary impact that ultra-short bursts of HIT (high intensity training) can have, whatever your age or level of fitness. In Fast Exercise, Michael Mosley, a self-confessed sloth, teams up with super-fit health journalist Peta Bee to dispel common exercise myths. They offer practical advice and a range of workouts that take just a few minutes a day and can be done any time, anywhere. Fast Exercise is for everyone: those who don’t enjoy exercise but want to lose fat and stay healthy, those who love exercise and want to enhance their performance, and those who just want to understand the science behind it all.

Milton, Evil and Literary History addresses the ways in which we read literary history according to quite specific images of growth, development, progression, flourishing and succession. Goodness has always been aligned with a life of expansion, creation, production and fruition, while evil is associated with the inert, non-relational, static and stagnant. These associations have also underpinned a distinction between good and evil notions of capitalism, where good exchange enables agents to enhance their living potential and is contrasted with the evils of a capitalist system that circulates without any reference to life or spirit. Such images of a ghostly and technical economy divorced from animating origin are both central to Milton's theology and poetry and to the theories of literary history through which Milton is read. Regarded as a radical precursor to Romanticism, Milton's poetry supposedly requires the release of his radical spiritual content from the fetters of received orthodoxy. This literary and historical imagery of releasing the radical spirit of a text from the dead weight of received tradition is, this book argues, the dominant doxa of historicism and one which a counter-reading of Milton ought to question.

The diversity of animal signals has been widely documented, and the generality of animal signals also tantalizingly suggests that there are common mechanisms that have selected for their origin. However, while much progress has been made on some fronts, we still lack a general theory about why the diversity of signaling structures exist. Our compilation will directly address this gap by focusing on an exciting new arena of sexual selection, namely using functional approaches to understand signaling. This approach is rooted in the idea that many signals are designed to transmit important functional imformation that is both important for issues of male quality (and hence male competition), and female choice. The increasing use of technology in sexual selection studies has enabled researchers to test whether signaling is either constrained by, or accurately transmits information about functional capacities. Further, in animals that fight vigorously, functional capacities such as endurance or strength may make the difference between winning and losing. This volume brings together a diverse collection of researchers who are actively investigating how function and signaling are related. These researchers use both a variety of methods and taxa to study animal signaling, and we believe that this integrative view is important to open up fresh vistas for why animal signals have evolved.

We are in the midst of a revolution. It is a scientific revolution built upon the tools of molecular biology, with which we probe and prod the living world in ways unimaginable a few decades ago. Need to track a bacterium at the root of a hospital outbreak? No problem: the offending germ's complete genetic profile can be obtained in 24 hours. We insert human DNA into E. coli bacteria to produce our insulin. It is natural to look at biotechnology in the 21st century with a mix of wonder and fear. But biotechnology is not as 'unnatural' as one might think. All living organisms use the same molecular processes to replicate their genetic material and the same basic code to 'read' their genes. The similarities can be seen in their DNA. Here, John Archibald shows how evolution has been 'plugging-and-playing' with the subcellular components of life from the very beginning and continues to do so today. For evidence, we need look no further than the inner workings of our own cells. Molecular biology has allowed us to gaze back more than three billion years, revealing the microbial mergers and acquisitions that underpin the development of complex life. One Plus One Equals One tells the story of how we have come to this realization and its implications.
