Shhh! The biggest idea ever!

Natural selection's explanatory power is not just about life on this planet: it is the only theory so far suggested that could explain life on any planet. If life exists anywhere else in the universe then some version of evolution by natural selection will almost certainly turn out to underpin its existence.
But what makes natural selection so special? A powerful idea assumes little to explain much. It does lots of explanatory 'heavy lifting', while expending little in the way of assumptions or postulations. It gives you plenty of bangs for your explanatory buck. Its Explanation Ratio - what it explains, divided by what it needs to assume in order to do the explaining - is enormous.
If any reader knows of any idea that has a larger explanation ratio than
Yet the denominator (the number at the bottom of the fraction) in the explanatory equation is spectacularly small and simple. The denominator is: natural selection, the non-random survival of genes in gene pools (to put it in neo-Darwinian terms rather than
You can winnow Darwin's big idea down to a single sentence (again, this is a modern way of putting it, not quite Darwin's): 'Given sufficient time, the non-random survival of hereditary entities will generate complexity, diversity, beauty, and an illusion of design so persuasive that it is almost impossible to distinguish from deliberate intelligent design'. We don't need to add mutation to our assumptions. Mutational 'bucks' are provided free. 'Given sufficient time' is not a problem either - except for human minds struggling to take on board the terrifying magnitude of geological time. Look around you, the illusion of design is everywhere in the living world. So powerful is this illusion, so soft and comfortable and beguiling is the cotton wool over our eyes, that the spell of the illusion was only recently lifted 150 years ago today. Yes, 2009 is the 150th anniversary of Darwin's big idea - And our eyes are still accustomising to the brilliant new view.
It is mainly its power to simulate the illusion of design that makes
But intelligent design is the polar opposite of a powerful theory: its explanation ratio is pathetically titchy. The numerator is the same as
I'll end on a subtler legacy of
