From the world-renowned geobiologist and bestselling author of A Brief History of Earth, the epic story of a planetary conversation four billion years in the making.
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 (Princeton). Recipient of the International Prize for Biology and the Crafoord Prize in Geosciences, he is a member of the National Academy of Sciences.
"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 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."
