Britain's foremost astrobiologist offers an accessible and game-changing account of why life is like it is. The puzzles of life astound and confuse us like no other mystery. But in this revolutionary new book, Charles Cockell reveals how nature is far more understandable and predictable than we think. Refining Darwin's theory of natural selection, Cockell puts forward a remarkable and elegant account of why evolution has taken the paths it has. From animals to atoms, he shows that is it not biology, but physics, which is the true touchstone for understanding life in all its extraordinary forms. _______________ An intriguing and enthralling adventure into the physics of life that is all around us and inside us. Cockell provides a reminder of the seeming rarity of all this beauty but also an invitation to look up to the skies and ask 'where else might something like this be?' - Robin Ince - Presenter of BBC Radio 4's Infinite Monkey Cage Riveting... Cockell is not only a fine scientist but a fine writer too. - Sir Martin Rees - Astronomer Royal and former President of the Royal Society
