Claim CA002.2:
Marx sent a personally inscribed copy of the second edition of Das
 Kapital
to Darwin and wanted to dedicate it to him, but Darwin wrote a letter
politely declining.

Response:
-  Darwin wrote a letter declining the dedication of an unnamed book on
   atheism, but he wrote it to Edward Aveling.  Aveling's common-law wife
   was Elanor Marx, Karl's daughter, and she inherited his papers.  They
   got mixed up with Karl Marx's papers, and the letter was assumed to
   have been to Marx.  This view found ideological favor in Russia, so it
   was widely repeated.  Later, a letter from Aveling, requesting
   permission to dedicate his book The Student's Darwin to Darwin, was
   found among Darwin's papers.
   Darwin declined permission and argued that science should not address
   religious matters directly (Colp 1982; Carter 2000).
 -  Darwin did have a copy of Das Kapital, but its pages were unseparated
   when he died, so he never read it.
 -  None of this matters to the science of evolution.
