This has been a banner year for Charles Darwin: the 200th anniversary of his birth, and today the 150th anniversary of the book that changed the world.
I've been posting about Darwin and his work all year, but couldn't let the day go by without saluting (and later raising a glass to) the best literary/scientific book I've ever read.
Thanks, Mr. Darwin. And may the fruits of your labor continue to inspire scientists and lay folk alike.
