Oxygen has had extraordinary effects on life. Three hundred million years ago, in Carboniferous times, dragonflies grew as big as seagulls, with wingspans ofnearly a metre. Researchers claim they could have flown only if the air had contained more oxygen than today -probably as much as 35 per cent. Giant spiders, tree-ferns, marine rock formations and fossil charcoalsall tell the same story. High oxygen levels may also explain the global firestorm that contributed to thedemise of the dinosaurs after the asteroid impact. The strange and profound effects that oxygen has had on the evolution of life pose a riddle, which this booksets out to answer. Oxygen is a toxic gas. Divers breathing pure oxygen at depth suffer from convulsionsand lung injury. Fruit flies raised at twice normal atmospheric levels of oxygen live half as long as theirsiblings. Reactive forms of oxygen, known as free radicals, are thought to cause ageing in people. Yet ifatmospheric oxygen reached 35 per cent in the Carboniferous, why did it promote exuberant growth,instead of rapid ageing and death? Oxygen takes the reader on an enthralling journey, as gripping as a thriller, as it unravels the unexpectedways in which oxygen spurred the evolution of life and death. The book explains far more than the size ofancient insects: it shows how oxygen underpins the origin of biological complexity, the birth of photosynthesis, the sudden evolution of animals, the need for two sexes, the accelerated ageing of cloned animals like Dolly the sheep, and the surprisingly long lives of bats and birds. Drawing on this grand evolutionary canvas, Oxygen offers fresh perspectives on our own lives and deaths,explaining modern killer diseases, why we age, and what we can do about it. Advancing revelatory new ideas,following chains of evidence, the book ranges through many disciplines, from environmental sciences tomolecular medicine. The result is a captivating vision of contemporary science and a humane synthesis of ourplace in nature. This remarkable book will redefine the way we think about the world.

This book can be treated as the bible of Oxygen. I enjoyed the author's style of writing about O2 and various related topics. This is a book on the chemistry of Oxygen and how it influenced the formation of life on our planet. Read full review

User Review  - Steve - Goodreads

This is a fascinating book, arguing that the evolution of life in an oxygen atmosphere has direct implications for aging and age-related diseases. It also effectively (in my mind) argues that medical ... Read full review
