One of the memorable moments involves Oliver hunting and eating crocodile, and it tastes like chicken. “What they are saying without knowing it, is that both taste like dinosaur”. Cute line. But wrong. Birds may be descended from dinosaurs, but crocodiles are not: they branched off from archosaurs. That’s the kind of sloppy thinking that typifies this book. It is sententious and second-hand. No doubt a TV series will come along in the fullness of time. Wisdom of the Ancients? Well, make your own mind up.
