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

Magisterial and collegial, this may be the biology book of the year * Booklist *
Fascinating . . . Cockell offers surprising insights * Sean Carroll, author of The Particle at the End of the Universe *
An invaluable guide... Life is generally described as a matter of contingency: what we find in nature is the result of countless historical accidents. In The Equations of Life, Charles Cockell provides an important counterbalance to that picture. * Philip Ball, author of Critical Mass *
A lucid, provocative argument that the dazzling variety of organisms produced by 4 billion years of evolution may seem unbounded, but all follow universal laws. * Kirkus *
Enlightening and entertaining... Whether on this third rock from the Sun or another planet in a far-distant galaxy, creatures should share forms and behaviours shaped by the forces of natural selection and the fundamental laws of physics that reign throughout the universe. * Lee Billings, author of Five Billion Years of Solitude *
Fascinating. A profound exploration of the deep nexus between physics and biology. * Andreas Wagner, professor of evolutionary biology at the University of Zürich and author of Arrival of the Fittest *
