Untestable Claims and the Evolution of Consciousness

No one has solved the ‘hard problem’ of consciousness until now, claim Feinberg and Mallatt; no one has bridged the ‘explanatory gap’ between mind and brain before. But they claim to have done it by finding ‘the basic requirements for consciousness’, tracing when and where these first appeared and so discovering that consciousness emerged between 560 and 520 million years ago during the Cambrian explosion. If they had really succeeded this would indeed mark the ‘Holy Grail of consciousness studies’.
