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. Paleontologist and geobiologist Andrew Knoll reveals why we should listen to both voices—the physical and the biological—to understand how we and our planet became possible.
Surveying 4 billion years of history, he shows how Earth and life interact to cycle the elements of life from rocks, water, and air, and how these and related processes control climate, regulate the atmosphere, and support the diversification of life-forms great and small.
Knoll’s book Earth and Life: A Four Billion Year Conversation (Princeton University Press) is available for purchase.
