A Times and Sunday Times Book of the Year. A Waterstones Best Book of 2020. In his acclaimed book, Other Minds, Peter Godfrey-Smith explored the mind of the octopus – the closest thing to an intelligent alien on Earth. In Metazoa, he expands his inquiry to animals at large, investigating the evolution of experience with the assistance of far-flung species. Following the evolutionary paths of a glass sponge, soft coral, banded shrimp, octopus and fish, then moving onto land and the world of insects, birds and primates like ourselves, Metazoa gathers stories together to bridge the gap between matter and mind and address one of the most important philosophical questions: what is the origin of consciousness? Combining vivid animal encounters with philosophy and biology, Metazoa reveals the impossibility of separating the evolution of our minds from the evolution of animals themselves.
