Abstract
n one of the numerous movie versions of A Christmas Carol , Ebenezer Scrooge, mounting the steps to visit his dying partner, Jacob Marley, encounters a dignified gentleman sitting on a landing. "Are you the doctor?" Scrooge inquires. "No," replies the man, "I'm the undertaker; ours is a very competitive business." The cutthrought world of intellectuals must rank a close second, and few events attract more notice than a proclamation that popular ideas have died. Darwin's theory of natural selection has been a perennial candidate for burial.
