The Ancient Origins of Consciousness

A very level-headed, deeply informed, and magisterial approach to the neurobiological basis of consciousness that considers the evolutionary history, the neuroanatomy, and the behavior of extant animals. The book casts a wide net and pinpoints the origin of consciousness to the time of the Cambrian explosion.

The Ancient Origins of Consciousness will get you thinking about thinking in a way you never have before. This important, challenging, and surely controversial book opens the possibility that our world's fellow creatures are far more alert, alive, and sentient than many scientists and philosophers have previously suggested. I hope it's read widely and discussed with vigor by both academics and laypersons alike.

This book provides a much-needed evolutionary context for examining the origin and material basis of sentience and consciousness. Treating these as adaptive responses to real biological needs, each with its own evolutionary history, demystifies a subject too often framed in a top-down, primate-centric way. Progress in science often depends on first tackling the simplest available example, as with the hydrogen molecule in the case of chemical bond theory. For the biological problem of sentience and consciousness, the equivalent is to seek rudimentary forms of these phenomena as they emerge in evolution. This is the perspective of the authors, who develop their argument at some length in a thought-provoking and insightful way.

This book's argument that consciousness probably extends hugely further back in time than we commonly suppose is welcome. It is a thoughtful and immensely informative survey of evolutionary neurobiology, which is sure to become a classic in the field of consciousness studies.

[Feinberg and Mallatt's] neuroevolutionary approach is the best we will have if we are to respect the power of our own human consciousness and also to locate it within a biological framework.
