I came up with a brilliant analogy this morning – that Darwin’s conclusions might serve as an analogy for art/theatre, which is continually evolving, adapting to reflect changing tastes, times, budgets and politics.   Then open Richard Eyre’s What Do I know? and read “The dictates of artistic endeavour are very harsh.  It’s a Darwinian universe whose creatures are governed by the law of survival of the fittest.”  Damn!
