‘A highly enjoyable read with clear explanations of molecular biology and quantum physics – and then speculations in search of a borderland between them. It is not a question of whether quantum mechanics is needed to understand biochemical processes, but exactly where, and at what level. For sure we need quantum ideas to understand in detail how enzymes work. Maybe we need them too for those two great puzzles of evolution: the origin of life and the physical roots of conscious experience.’
GRAHAM CAIRNS-SMITH, author of Seven Clues to the Origin of Life
‘If you want a short course in the greatest scientific insights of the last two centuries – evolution in the nineteenth and quantum mechanics in the twentieth – Quantum Evolution is the ideal primer. Its purpose, though, isn’t to rescue the scientifically undereducated, it’s far, far more ambitious … Patient, clear and logical, a masterful job … [and] a hard, wild and amazing trip.’ DAVID BROWN, Washington Post

CONTENTS
Starlight glistens on a spaceship’s silvery hull as it cruises, unseen and unmanned, amongst the planets of a distant solar system. Guided by the encoded instructions of an alien civilization it glides past dark, rocky planetary outposts and bloated gas giants until it reaches its goal, and swings into the orbit of an inner planet. A probe is released. Retrorockets fire that adjust the probe’s trajectory, easing it slightly from the mother-ship’s geostationary orbit and turning its heat-resistant nose towards the ground. The grip of the planet’s gravity drags the probe inwards, through ever-decreasing orbits. Faster and faster it spins until, plunging through clouds, it finally emerges under a leaden sky. A parachute is released to halt the headlong dive, and the craft slowly descends to land on a rock-strewn landscape.
Minutes later, a metallic lid is drawn back, exposing a camera lens, and pictures are beamed back to the mother-ship. The camera pans across the rocky scene. The same rubble-strewn landscape is everywhere – rocks of all shapes and sizes lie sunken into fine grey sand. The air is still. Nothing moves. The camera scans the monotonous surface stretching in all directions towards the horizon – grey rocks, some precariously balanced atop others, others lie shattered, blasted by the forces of alien weather. The camera pans again, and then one rock, in shape and colour much like any other, spreads its
