The eagerly anticipated conclusion to Peter Godfrey-Smith's three-part exploration of the origins of intelligence on Earth, which began with the bestselling Other Minds in 2018 and continued with Metazoa in 2020. The eagerly anticipated conclusion to Peter Godfrey-Smith's three-part exploration of the origins of intelligence on Earth, which began with the bestselling Other Minds in 2018 and continued with Metazoa in 2020. Peter Godfrey-Smith, the scuba-diving philosopher, examined the evolution of sentience in Other Minds. In Metazoa he asked how that consciousness shaped and was shaped by animal bodies. Now, in Living on Earth, he takes that line of questioning a step further, asking, how has life shaped and been shaped by our planet? He visits the largest living stromatolite fields, examples of how cyanobacteria began belching oxygen into the atmosphere as they converted carbon dioxide and water into living matter using the sun's light. The extraordinary increase in oxygen in the atmosphere resulted in an explosion in the diversity of life. And so began a riotous tangle of coevolution between plants and animals, as each changed the environment around them allowing others to utilise these new ecosystems and thus new species to evolve. From cyanobacteria, through algae on to ferns or trees or grasses, and from protists , through invertebrates and fish through the dinosaurs and on to birds and mammals – our planet has seen an explosion of life forms, all reacting to their environment and all creating new environments that allow other life to evolve. In our own evolutionary line, an initially unremarkable mammal changed in new ways, evolving to come out of the trees to inhabit new savannas and then onto inhabit the whole planet. One of the most adaptable species ever found on Earth, and arguably the species causing the most change, humans are still part of this 3.8 billion year history of life forms changing the world around them. In Living on Earth, Godfrey-Smith takes us on a grand tour of the history of life on earth. He visits Rwandan gorillas and Australian bowerbirds, returns to coral reefs and octopus dens, considers the impact of language and writing, and weighs the responsibilities our unique powers bring with them, as they relate to factory farming, habitat preservation, climate change, and the use of animals in experiments. Living on Earth shows that Humans belong to the infinitely complex system that is the Earth, and our minds are products of that system, but we are also an acting force within it. We are creatures of Earth, but we hold Earth's future in our hands. It is a responsibility that we must all understand and accept.

      Godfrey-Smith (Metazoa), a philosophy of science professor at the University of Sydney, presents a cerebral meditation on “the history of how life has changed the Earth.” He explains how three billion years ago, microorganisms called cyanobacteria started photosynthesizing, pumping oxygen into the atmosphere and paving the way for complex organisms. Ancient algae “crept onto land sometime around 450 million years ago,” Godfrey-Smith writes, describing how the emergence of forests with large root systems some 40 million years later reshaped terrain by holding together riverbanks and redirecting currents. Arguing that animals are “causes rather than evolutionary products” of their environment, Godfrey-Smith describes how some octopuses dig tunnels 50 centimeters deep and how male bowerbirds build vertical nestlike structures to impress potential mates. Unfortunately, it’s difficult to follow the author’s train of thought in the latter half of the book, which is aimed at answering, “What are minds doing here?” To “guide action,” is the author’s answer, but the broadness of that response leads to meandering discussions on the materialist view of the mind, the origin of consciousness, the relationship between written language and time, and the ethics of farming livestock. There’s no question Godfrey-Smith is an erudite and profound thinker, but he’s not always successful in organizing his ideas in ways that readers will understand. This doesn’t quite fulfill its lofty ambitions. Agent: Sarah Chalfant, Wylie Agency.
