Earth evolves. From first atom to molecule, mineral to magma, granite crust to single cell to verdant living landscape, ours is a planet constantly in flux. In this radical new approach to Earth's biography, senior Carnegie Institution researcher and national best-selling author Robert M. Hazen reveals how the co-evolution of the geosphere and biosphere - of rocks and living matter - has shaped our planet into the only one of its kind in the Solar System, if not the entire cosmos.

With an astrobiologist's imagination, a historian's perspective, and a naturalist's passion for the ground beneath our feet, Hazen explains how changes on an atomic level translate into dramatic shifts in Earth's makeup over its 4.567 billion year existence. He calls upon a flurry of recent discoveries to portray our planet's many iterations in vivid detail - from its fast-rotating infancy when the Sun rose every 5 hours and the Moon filled 250 times more sky than it does now, to its sea-bathed youth, before the first continents arose; from the Great Oxidation Event that turned the land red, to the globe-altering volcanism that may have been the true killer of the dinosaurs. Through Hazen's theory of "co-evolution," we learn how reactions between organic molecules and rock crystals may have generated Earth's first organisms, which in turn are responsible for more than two-thirds of the mineral varieties on the planet - thousands of different kinds of crystals that could not exist in a nonliving world.
