The fine details of evolutionary history and neuroanatomy are notoriously complex, and well larded with unpronounceable dog-Latin terms, and they don’t make for easy reading. But the authors write with elegance and lightness of touch, and have been blessed with a superb illustrator. As we can’t wind the tape of history back and rerun it, we’ll never be able to be sure that the story Feinberg and Mallatt tell is right in all its details, but their 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. As they cheerfully admit, neuroevolution does not solve the “hard problem”. But then perhaps it isn’t a real problem at all, but a ghostly remnant of a past dualistic way of thinking. Premios
"How is consciousness created? When did it first appear on Earth, and how did it evolve? What constitutes consciousness, and which animals can be said to be sentient? In this book, Todd Feinberg and Jon Mallatt draw on recent scientific findings to answer these questions--and to tackle the most fundamental question about the nature of consciousness: how does the material brain create subjective experience? After assembling a list of the biological and neurobiological features that seem responsible for consciousness, and considering the fossil record of evolution, Feinberg and Mallatt argue that consciousness appeared much earlier in evolutionary history than is commonly assumed. About 520 to 560 million years ago, they explain, the great "Cambrian explosion" of animal diversity produced the first complex brains, which were accompanied by the first appearance of consciousness; simple reflexive behaviors evolved into a unified inner world of subjective experiences. From this they deduce that all vertebrates are and have always been conscious--not just humans and other mammals, but also every fish, reptile, amphibian, and bird. Considering invertebrates, they find that arthropods (including insects and probably crustaceans) and cephalopods (including the octopus) meet many of the criteria for consciousness. The obvious and conventional wisdom--shattering implication is that consciousness evolved simultaneously but independently in the first vertebrates and possibly arthropods more than half a billion years ago. Combining evolutionary, neurobiological, and philosophical approaches allows Feinberg and Mallatt to offer an original solution to the 'hard problem' of consciousness"--MIT CogNet.
