The "demons" Davies has in mind are of the Maxwellian kind, taking the specific form of proteinaceous nanomachines. A few of the book's main points: (1) Biological processes can be reminiscent of computation, and the concepts of software and information flow are relevant to their description. (2) "Darwinism 2.0" recognizes evolution of evolvability itself and may thus seem to incorporate a touch of Lamarckism; mutations are not totally random, and a cell's DNA may be writable to some extent. (3) Some "demons" may permit quantum coherence to persist long enough for quantum processes to really be important in biology. (4) Tononi's Integrated Information Theory "is a laudable attempt to get to grips with consciousness in a quantitative way and to provide a theoretical underpinning based on causality and information flow."

How does life create order from chaos? And just what is life, anyway? Leading physicist Paul Davies argues that to find the answers, we must first answer a deeper question- 'What is information?' To understand the origins and nature of life, Davies proposes a radical vision of biology which sees the underpinnings of life as similar to circuits and electronics, arguing that life as we know it should really be considered a phenomenon of information storage. In an extraordinary deep dive into the real mechanics of what we take for granted, Davies reveals how biological processes, from photosynthesis to birds' navigation abilities, rely on quantum mechanics, and explores whether quantum physics could prove to be the secret key of all life on Earth. Lively and accessible, The Demon in the Machineboils down intricate interdisciplinary developments to take readers on an eye-opening journey towards the ultimate goal of science- unifying all theories of the living and the non-living, so that humanity can at last understand its place in the universe.

Biology is still a strange science, exceptions outweigh the rule when you try to make any statement, there is a lack of fundamental principles to follow and even being able to effect a measurement reliably is completely non trivial.
However this state is unlikely to remain like this forever and the direction of a new way to identify principles in biological sciences will include information as a metric and evolutionary “optionality”.
Paul Davies in this book brings something new evem to people that feel they know contemporary biological methods.
On the down side the book is less accessible than other texts by the author ans requires attentive reading. ( )
