How did the world as we know it—from the soil beneath our feet to the air we breathe and the life that surrounds us—come to be? Geologists have proposed one set of answers while biologists have proposed another. Earth and Life is the first book to reveal why we need to listen to both voices—the physical and the biological—to understand how we and our planet became possible.
In this captivating book, Andrew Knoll traces how all life is sustained by Earth’s geological and atmospheric dynamics, and how life itself shapes the physical environment. Taking readers on a thrilling journey across four billion years of Earth history, he shows how Earth and life interact to cycle the very elements of life from rocks, water, and air, and how these and related processes control our climate, regulate our atmosphere, and support the diversification of life-forms great and small. Along the way, Knoll explains how we can draw on this history as we navigate the challenges of the Anthropocene, and how it can aid our search for life elsewhere in the universe.
Blending cutting-edge science with illuminating insights from a leading expert, Earth and Life explains how this ongoing interplay holds vital lessons for us today as humanity becomes an increasingly major voice in the conversation.
Andrew H. Knoll is the Fisher Research Professor of Natural History and Earth and Planetary Sciences, Emeritus, at Harvard University. His books include A Brief History of Earth: Four Billion Years in Eight Chapters and Life on a Young Planet: The First Three Billion Years of Evolution on Earth (¿ìɫֱ²¥). Recipient of the International Prize for Biology and the Crafoord Prize in Geosciences, he is a member of the National Academy of Sciences.
"A stimulating primer on how interactions between the planet's physical environment and living beings have shaped the world throughout time. . . . Knoll does an impressive job of lucidly explaining both geological and biological processes, providing necessary background without being pedantic. Readers will be informed and entertained."—Publishers Weekly
"A welcome look at the Earth as a single system of countless moving parts."—Kirkus Reviews
“A tour de force. Weaving together the two greatest stories on Earth—the evolution of life and of the planet itself, Andrew Knoll reveals the dynamic dialogue that created our world. There is grandeur in this new and hard-earned view. You will never look at our planet—or others—in the same way.”—Sean B. Carroll, author of A Series of Fortunate Events and The Serengeti Rules
“This book is described as a conversation, and that is indeed what it is: a jovial, engaging, witty, and enlightening fireside chat with one of the world’s eminent experts on the evolution of life and how Earth has changed over time. It feels like banter with a friend, but by the end of it, you’ll come to appreciate how life and Earth have been intertwined for four billion years, and what that means for our present, and our future.”—Steve Brusatte, New York Times bestselling author of The Rise and Fall of the Dinosaurs
“A vital guide to the intimate interplay between geology and biology over Earth’s history. Knoll tells an utterly compelling story of how life itself draws the elements needed from the fabric of the planet around it, and how the thriving world as we know it became possible.”—Lewis Dartnell, author of Origins: How the Earth Shaped Human History
“A world leader in his field for decades, Knoll provides a rigorous insider’s perspective grounded in his personal journey and stitched through every chapter. Readers will be entertained and left with a rich understanding of the intertwined evolution of Earth and its life over billions of years.”—Timothy Lyons, University of California, Riverside
“In his ambitious new book, Knoll describes the steadily maturing field of geobiology, which examines the interactions between our planet Earth and its biota. The biota are clearly dependent on planetary characteristics that enhance its habitability; yet, the planet itself is increasingly being influenced by the biota, including humans, and not all of these interactions are necessarily beneficial. Although the main part of the book is devoted to describing Earth’s long prehuman history—where the author is an acknowledged expert—the final chapters reveal his concerns about where we are currently heading. Knoll’s writing is clear and accessible and should appeal to a wide range of audiences.”—James F. Kasting, author of How to Find a Habitable Planet
