Can a mere stage play attempt to do adequate justice to the controversial theories and complex life of the great Charles Darwin…? Absolutely not. So, instead, enjoy this constantly mutating romp through every species of theatre, from music hall to panto, from melodrama to domestic realism, from Brecht to Artaud, from BBC costume drama to Sam Beckett.

And maybe, after all that, some sense of the real drama of Charles Darwin will have evolved by the end.
