Three hundred million years ago, in Carboniferous times, dragonflies grew as big as seagulls, with wingspans of nearly a meter. Researchers claim they could have flown only if the air had contained more oxygen than today - probably as much as 35 percent. Giant spiders, tree ferns, marine rock formations, and fossil charcoals all tell the same story. High oxygen levels may also explain the global firestorm that contributed to the demise of the dinosaurs after the asteroid impact.
The strange and profound effects that oxygen has had on the evolution of life pose a riddle that this audiobook sets out to answer. Oxygen is a toxic gas. Divers breathing pure oxygen at depth suffer from convulsions and lung injury. Fruit flies raised at twice the normal atmospheric levels of oxygen live half as long as their siblings. Reactive forms of oxygen, known as free radicals, are thought to cause aging in people. Yet if atmospheric oxygen reached 35 percent in the Carboniferous, why did it promote exuberant growth instead of rapid aging and death?
Oxygen takes the listener on an enthralling journey, as gripping as a thriller, as it unravels the unexpected ways in which oxygen spurred the evolution of life and death.
About the Author
Nick Lane is a biochemist and writer. He is a Professor of Evolutionary Biochemistry in the Department of Genetics, Evolution and Environment at University College London. “Like his forebears in that same department — Steve Jones, JBS Haldane — he’s that rare species, a scientist who can illuminate the bewildering complexities of biology with clear, luminous words” (The Observer). His research focuses on the role of bioenergetics in the origin of life and the evolution of cells. Nick was awarded the first UCL Provost’s Venture Research Prize in 2009 and the 2015 Biochemical Society Award. He has published four critically acclaimed books, which have been translated into 20 languages. Life Ascending won the 2010 Royal Society Prize for Science Books. His books have been shortlisted for two other literary prizes and named a book of the year by the Economist, Independent, Times, Sunday Times and New Scientist.
