It can't have escaped your notice that we're celebrating the bicentenary of Charles Darwin's birth and at the same time the 150th anniversary of the publication of the Origin of the Species.
John pointed out this curious service at Westminster Abbey to celebrate the man; go here to see how Damien Hirst is celebrating the book (see pic above)
NB If you haven't [re-]read Origin of the Species, you really should. Grasping received ideas are one thing, but as we mere hacks suspect, the received ideas might not represent all that is to be said on the subject. And for all the reverence bestowed on him and his ideas by scientists, Darwin is probably the most misunderstand writer of the modern era. So the "received" version of Darwin is quite a long way from his original work.
