I saw a review of this book in The Economist a couple months ago, and I had the exact same reaction as Sawyer. I'd love to see the rogues' take this on.
From what cursory browsing of the literature, it seems like it is possible that quantum effects play some role in photosynthesis and in animal magnetic navigation. This comes with several major caveats, though. The experimental evidence is highly preliminary. The modeling work is completely legit, but, as is often the case with mathematical modeling, the connection to reality is tenuous. Furthermore, even if there are quantum effects in these processes, it does not mean that they are important. It seems more likely that, even if these effects prove true, they will end up more as interesting trivia than a revolution in our understanding of biology.
Nonetheless, there is real, respected, peer-reviewed work in this field. The thing that worries me is the hype surrounding it. I cringe when I see Ted talks and mass market books getting out ahead of the science. Maybe the scientists should focus on laying the foundations for the field first, and then do the marketing second.
